Breast cancer

 

Docadex in combination with doxorubicin and cyclophosphamide is indicated for the adjuvant treatment of patients with:

•   operable node-positive breast cancer

•  operable node-negative breast cancer

 

For patients with operable node-negative breast cancer, adjuvant treatment should be restricted to patients eligible to receive chemotherapy according to internationally established criteria for primary therapy of early breast cancer (see section 5.1).

 

Docadex in combination with doxorubicin is indicated for the treatment of patients with locally advanced or metastatic breast cancer who have not previously received cytotoxic therapy for this condition.

 

Docadex monotherapy is indicated for the treatment of patients with locally advanced or metastatic breast cancer after failure of cytotoxic therapy. Previous chemotherapy should have included an anthracycline or an alkylating agent.

 

Docadex in combination with trastuzumab is indicated for the treatment of patients with metastatic breast cancer whosetumors over express HER2 and who previously have not received chemotherapy for metastatic disease.

 

Docadex in combination with capecitabine is indicated for the treatment of patients with locally advanced or metastatic breast cancer after failure of cytotoxic chemotherapy. Previous therapy should have included an anthracycline.

 

Non-small cell lung cancer

 

Docadex is indicated for the treatment of patients with locally advanced or metastatic non-small cell lung cancer after failure of prior chemotherapy.

 

Docadex in combination with cisplatin is indicated for the treatment of patients with unresectable, locally advanced or metastatic non-small cell lung cancer, in patients who have not previously received chemotherapy for this condition.

 

Prostate cancer

 

Docadex in combination with prednisone or prednisolone is indicated for the treatment of patients with hormone refractory metastatic prostate cancer.

 

Gastric Adenocarcinoma

 

Docadex in combination with cisplatin and 5-fluorouracil is indicated for the treatment of patients with metastaticgastric adenocarcinoma, including adenocarcinoma of the gastroesophageal junction, who have not received prior chemotherapy for metastatic disease.

 

Head and neck cancer

 

Docadex in combination with cisplatin and 5-fluorouracil is indicated for the induction treatment of patients with locally advanced squamous cell carcinoma of the head and neck.

The use of docetaxel should be confined to units specialised in the administration of cytotoxic chemotherapy and it should only be administered under the supervision of a physician qualified in the use of anticancer chemotherapy (see section 6.6).

 

Recommended dosage

 

For breast, non-small cell lung, gastric, and head and neck cancers, premedication consisting of an oral corticosteroid, such as dexamethasone 16 mg per day (e.g. 8 mg BID) for 3 days starting 1 day prior to docetaxel administration,unless contraindicated, can be used (see section 4.4). Prophylactic G-CSF may be used to mitigate the risk of hematological toxicities.

For prostate cancer, given the concurrent use of prednisone or prednisolone the recommended premedication regimen is oral dexamethasone 8 mg, 12 hours, 3 hours and 1 hour before the docetaxel infusion (see section 4.4).

 

Docetaxel is administered as a one-hour infusion every three weeks.

 

Breast cancer

In the adjuvant treatment of operable node-positive and node-negative breast cancer, the recommended dose ofdocetaxel is 75 mg/m² administered 1-hour after doxorubicin 50 mg/m² and cyclophosphamide 500 mg/m² every 3 weeks for 6 cycles (TAC regiment) (see also Dosage adjustments during treatment).

For the treatment of patients with locally advanced or metastatic breast cancer, the recommended dosage of docetaxel is 100 mg/m² in monotherapy. In first-line treatment, docetaxel 75 mg/m² is given in combination therapy with doxorubicin (50 mg/m²).

 

In combination with trastuzumab the recommended dose of docetaxel is 100 mg/m² every three weeks, with trastuzumab administered weekly. In the pivotal study the initial docetaxel infusion was started the day following the first dose of trastuzumab. The subsequent docetaxel doses were administered immediately after completion of the trastuzumab infusion, if the preceding dose of trastuzumab was well tolerated. For trastuzumab dosage and administration, see trastuzumab summary of product characteristics.

In combination with capecitabine, the recommended dose of docetaxel is 75 mg/m² every three weeks, combined with capecitabine at 1250 mg/m² twice daily (within 30 minutes after a meal) for 2 weeks followed by 1-week rest period. For capecitabine dose calculation according to body surface area, see capecitabine summary of product characteristics.

 

Non-small cell lung cancer

In chemotherapy naïve patients treated for non-small cell lung cancer, the recommended dose regimen is docetaxel 75 mg/m² immediately followed by cisplatin 75 mg/m² over 30-60 minutes. For treatment after failure of prior platinum-based chemotherapy, the recommended dose is 75 mg/m² as a single agent.

 

Prostate cancer

The recommended dose of docetaxel is 75 mg/m². Prednisone or prednisolone 5 mg orally twice daily is administered continuously (see section 5.1).

 

Gastric adenocarcinoma

The recommended dose of docetaxel is 75 mg/m² as a 1 hour infusion, followed by cisplatin 75 mg/m², as a 1 to 3hour infusion (both on day 1 only), followed by 5-fluorouracil 750 mg/m² per day given as a 24-hour continuous infusion for 5 days, starting at the end of the cisplatin infusion.

Treatment is repeated every three weeks. Patients must receive premedication with antiemetics and appropriatehydration for cisplatin administration. Prophylactic G-CSF should be used to mitigate the risk of hematological toxicities (See also Dosage adjustments during treatment).

 

Head and neck cancer

Patients must receive premedication with antiemetics and appropriate hydration (prior to and after cisplatin administration). Prophylactic G-CSF may be used to mitigate the risk of hematological toxicities. All patients on the docetaxel-containing arm of the TAX 323 and TAX 324 studies, received prophylactic antibiotics.

 

-                         Induction chemotherapy followed by radiotherapy (TAX 323)

For the induction treatment of inoperable locally advanced squamous cell carcinoma of the head and neck (SCCHN), the recommended dose of docetaxel is 75 mg/m² as a 1 hour infusion followed by cisplatin 75 mg/m²over 1 hour, on day one, followed by 5-fluorouracil as a continuous infusion at 750 mg/m² per day for five days. This regimen is administered every 3 weeks for 4 cycles. Following chemotherapy, patients should receive radiotherapy.

 

-                         Induction chemotherapy followed by chemoradiotherapy (TAX 324)

For the induction treatment of patients with locally advanced (technically unresectable, low probability of surgical cure, and aiming at organ preservation) squamous cell carcinoma of the head and neck (SCCHN), therecommended dose of docetaxel is 75 mg/m² as a 1 hour intravenous infusion on day 1, followed by cisplatin 100 mg/m² administered as a 30-minute to 3 hour infusion, followed by 5-fluorouracil 1000 mg/m²/day as a continuous infusion from day 1 to day 4. This regimen is administered every 3 weeks for 3 cycles. Following chemotherapy, patients should receive chemoradiotherapy.

 

For cisplatin and 5-fluorouracil dose modifications, see the corresponding summary of product characteristics.

 

Dose adjustments during treatment

 

General

Docetaxel should be administered when the neutrophil count is ≥ 1,500 cells/mm³. In patients who experienced either febrile neutropenia, neutrophil < 500 cells/mm³ for more than one week, severe or cumulative cutaneous reactions orsevere peripheral neuropathy during docetaxel therapy, the dose of docetaxel should be reduced from 100 mg/m² to 75mg/m² and/or from 75 to 60 mg/m². If the patient continues to experience these reactions at 60 mg/m², the treatment should be discontinued.

Adjuvant therapy for breast cancer

Primary G-CSF prophylaxis should be considered in patients who receive docetaxel, doxorubicin and cyclophosphamide (TAC) adjuvant therapy for breast cancer. Patients who experience febrile neutropenia and/or neutropenic infections should have their docetaxel dose reduced to 60 mg/m² in all subsequent cycles (see sections 4.4 and 4.8). Patients who experience Grade 3 or 4 stomatitis should have their dose decreased to 60 mg/m².

 

In combination with cisplatin

For patients who are dosed initially at docetaxel 75 mg/m² in combination with cisplatin and whose nadir of platelet count during the previous course of therapy is < 25,000 cells/mm³, or in patients who experience febrile neutropenia, or in patients with serious non-hematologic toxicities, the docetaxel dosage in subsequent cycles should be reduced to 65 mg/m². For cisplatin dosage adjustments, see manufacturer’s summary of product characteristics.

 

In combination with capecitabine

•  For capecitabine dose modifications, see capecitabine summary of product characteristics.

•   For patients developing the first appearance of Grade 2 toxicity, which persists at the time of the next docetaxel/capecitabine treatment, delay treatment until resolved to Grade 0-1, and resume at 100% of the original dose.

•   For patients developing the second appearance of Grade 2 toxicity, or the first appearance of a Grade 3 toxicity, at any time during the treatment cycle, delay treatment until resolved to Grade 0-1, then resume treatment with docetaxel 55 mg/m².

•  For any subsequent appearances of toxicities, or any Grade 4 toxicities, discontinue the docetaxel dose.

 

For trastuzumab dose modifications, see trastuzumab summary of product characteristics

 

In combination with cisplatin and 5-fluorouracil

If an episode of febrile neutropenia, prolonged neutropenia or neutropenic infection occurs despite G-CSF use, the docetaxel dose should be reduced from 75 to 60 mg/m². If subsequent episodes of

complicated neutropenia occur the docetaxel dose should be reduced from 60 to 45 mg/m². In case of Grade 4 thrombocytopenia the docetaxel dose should be reduced from 75 to 60 mg/m². Patients should not be retreated with subsequent cycles of docetaxel until neutrophils recover to a level > 1,500 cells/mm³ and platelets recover to a level > 100,000 cells/mm³. Discontinue treatment if these toxicities persist. (See section 4.4).

Recommended dose modifications for gastrointestinal toxicities in patients treated with docetaxel in combination with cisplatin and 5-fluorouracil (5-FU):

Toxicity	Dosage adjustment
Diarrhoea grade 3	First episode: reduce 5-FU dose by 20%. Second episode: then reduce docetaxel dose by 20%.
Diarrhoea grade 4	First episode: reduce docetaxel and 5-FU doses by 20%. Second episode: discontinue treatment.
Stomatitis/mucositis grade 3	First episode: reduce 5-FU dose by 20%. Second episode: stop 5-FU only, at all subsequent cycles. Third episode: reduce docetaxel dose by 20%.
Stomatitis/mucositis grade 4	First episode: stop 5-FU only, at all subsequent cycles. Second episode: reduce docetaxel dose by 20%.

For cisplatin and 5-fluorouracil dose adjustments, see the corresponding summary of product characteristics.

 

In the pivotal SCCHN studies patients who experienced complicated neutropenia (including prolonged neutropenia,febrile neutropenia, or infection), it was recommended to use G-CSF to provide prophylactic coverage (eg, day 6-15) in all subsequent cycles.

Special populations

 

Patients with hepatic impairment

Based on pharmacokinetic data with docetaxel at 100 mg/m² as single agent, patients who have both elevations of transaminase (ALT and/or AST) greater than 1.5 times the upper limit of the normal range (ULN) and alkaline phosphatase greater than 2.5 times the ULN, the recommended dose of docetaxel is 75 mg/m² (see sections 4.4 and5.2). For those patients with serum bilirubin > ULN and/or ALT and AST > 3.5 times the ULN associated with alkaline phosphatase > 6 times the ULN, no dose-reduction can be recommended, and docetaxel should not be used unless strictly indicated.

In combination with cisplatin and 5-fluorouracil for the treatment of patients with gastric adenocarcinoma, the pivotal clinical trial excluded patients with ALT and/or AST > 1.5 × ULN associated with alkaline phosphatase > 2.5 × ULN, and bilirubin > 1 x ULN; for these patients, no dose-reductions can be recommended and docetaxel should not be used unless strictly indicated. No data are available in patients with hepatic impairment treated by docetaxel in combination in the other indications.

 

This medicinal product contains 400 mg ethanol per ml concentrate. This has to be taken into account in high-risk groups such as patients with liver disease.

 

Pediatric population

The safety and efficacy of Docadex in nasopharyngeal carcinoma in children aged 1 month to less than 18 years have not yet been established.

There is no relevant use of Docadex in the pediatric population in the indications breast cancer, non-small cell lung cancer, prostate cancer, gastric carcinoma and head and neck cancer, not including type II and III less differentiated nasopharyngeal carcinoma.

 

Elderly

Based on a population pharmacokinetic analysis, there are no special instructions for use in the elderly. In combination with capecitabine, for patients 60 years of age or more, a starting dose reduction of capecitabine to 75% is recommended (see capecitabine summary of product characteristics)

Hypersensitivity to the active substance or to any of the excipients listed in section 6.1. Docetaxel must not be used in patients with baseline neutrophil count of < 1,500 cells/mm3. Docetaxel must not be used in patients with severe liver impairment since there is no data available (see sections 4.2 and 4.4). Contraindications for other medicinal products also apply, when combined with docetaxel.

For breast and non-small cell lung cancers, premedication consisting of an oral corticosteroid, such as dexamethasone 16 mg per day (e.g. 8 mg BID) for 3 days starting 1 day prior to docetaxel administration, unless contraindicated, can reduce the incidence and severity of fluid retention as well as the severity of hypersensitivity reactions. For prostatecancer, the premedication is oral dexamethasone 8 mg, 12 hours, 3 hours and 1 hour before the docetaxel infusion (see section 4.2).

 

Hematology

Neutropenia is the most frequent adverse reaction of docetaxel. Neutrophil nadirs occurred at a median of 7 days, butthis interval may be shorter in heavily pre-treated patients. Frequent monitoring of complete blood counts should be conducted on all patients receiving docetaxel. Patients should be retreated with docetaxel when neutrophils recover to a level ≥ 1,500 cells/mm³ (see section 4.2).

 

In the case of severe neutropenia (< 500 cells/mm³ for seven days or more) during a course of docetaxel therapy, a reduction in dose for subsequent courses of therapy or the use of appropriate symptomatic measures are recommended (see section 4.2).

In patients treated with docetaxel in combination with cisplatin and 5-fluorouracil (TCF), febrile neutropenia andneutropenic infection occurred at lower rates when patients received prophylactic G-CSF.

Patients treated with TCF should receive prophylactic G-CSF to mitigate the risk of complicated neutropenia (febrileneutropenia, prolonged neutropenia, or neutropenic infection). Patients receiving TCF should be closely monitored, (see sections 4.2 and 4.8).

 

In patients treated with docetaxel in combination with doxorubicin and cyclophosphamide (TAC), febrile neutropenia and/or neutropenic infection occurred at lower rates when patients received primary G-CSF prophylaxis. Primary G-CSF prophylaxis should be considered in patients who receive adjuvant therapy with TAC for breast cancer tomitigate the risk of complicated neutropenia (febrile neutropenia, prolonged neutropenia, or neutropenic infection). Patients receiving TAC should be closely monitored (see section 4.2 and 4.8).

 

Hypersensitivity reactions

Patients should be observed closely for hypersensitivity reactions especially during the first and second infusions.Hypersensitivity reactions may occur within a few minutes following the initiation of the infusion of docetaxel, thus facilities for the treatment of hypotension and bronchospasm should be available. If hypersensitivity reactions occur, minor symptoms such as flushing or localized cutaneous reactions do not require interruption of therapy. However, severe reactions, such as severe hypotension, bronchospasm or generalized rash/erythema require immediate discontinuation of docetaxel and appropriate therapy. Patients who have developed severe hypersensitivity reactions should not be re-challenged with docetaxel.

 

Cutaneous reactions

Localized skin erythema of the extremities (palms of the hands and soles of the feet) with edema followed bydesquamation has been observed. Severe symptoms such as eruptions followed by desquamation which lead to interruption or discontinuation of docetaxel treatment were reported (see section 4.2).

 

Fluid retention

Patients with severe fluid retention such as pleural effusion, pericardial effusion and ascites should be monitored closely.

 

Respiratory disorders

Acute respiratory distress syndrome, interstitial pneumonia/pneumonitis, interstitial lung disease, pulmonary fibrosis and respiratory failure have been reported and may be associated with fatal outcome. Cases of radiation pneumonitis have been reported in patients receiving concomitant radiotherapy.

If new or worsening pulmonary symptoms develop, patients should be closely monitored, promptly investigated, andappropriately treated. Interruption of docetaxel therapy is recommended until diagnosis is available. Early use of supportive care measures may help improve the condition. The benefit of resuming docetaxel treatment must be carefully evaluated.

 

Patients with liver impairment

In patients treated with docetaxel at 100 mg/m² as single agent who have serum transaminase levels (ALT and/orAST) greater than 1.5 times the ULN concurrent with serum alkaline phosphatase levels greater than

2.5 times the ULN, there is a higher risk of developing severe adverse reactions such as toxic deaths including sepsis and gastrointestinal hemorrhage which can be fatal, febrile neutropenia, infections, thrombocytopenia, stomatitis, andasthenia. Therefore, the recommended dose of docetaxel in those patients with elevated liver function test (LFTs) is 75 mg/m² and LFTs should be measured at baseline and before each cycle (see section 4.2).

For patients with serum bilirubin levels > ULN and/or ALT and AST > 3.5 times the ULN concurrent with serum alkaline phosphatase levels > 6 times the ULN, no dose-reduction can be recommended, and docetaxel should not be used unless strictly indicated.

In combination with cisplatin and 5-fluorouracil for the treatment of patients with gastric adenocarcinoma, the pivotal clinical study excluded patients with ALT and/or AST > 1.5 × ULN associated with alkaline phosphatase > 2.5 × ULN, and bilirubin> 1 x ULN; for these patients, no dose-reductions can be recommended and docetaxel should not be used unless strictly indicated. No data are available in patients with hepatic impairment treated by docetaxel in combination in the other indications.

 

Patients with renal impairment

There are no data available in patients with severely impaired renal function treated with docetaxel.

 

Nervous system

The development of severe peripheral neurotoxicity requires a reduction of dose (see section 4.2). Since Docadexcontains ethanol (400 mg ethanol per ml concentrate), consideration should be given to possible central nervous system and other effects.

 

Cardiac toxicity

Heart failure has been observed in patients receiving docetaxel in combination with trastuzumab, particularlyfollowing anthracycline (doxorubicin or epirubicin) containing chemotherapy. This may be moderate to severe and has been associated with death (see section 4.8).

 

When patients are candidates for treatment with docetaxel in combination with trastuzumab, they should undergobaseline cardiac assessment. Cardiac function should be further monitored during treatment (e.g. every three months) to help identify patients who may develop cardiac dysfunction. For more details see Summary of Product Characteristics of trastuzumab.

 

Eye disorders

Cystoid macular edema (CMO) has been reported in patients treated with docetaxel. Patients with impaired vision should undergo a prompt and complete ophthalmologic examination. In case CMO is diagnosed, docetaxel treatment should be discontinued, and appropriate treatment initiated (see section 4.8).

 

Others

Contraceptive measures must be taken by both men and women during treatment and for men at least 6 months after cessation of therapy (see section 4.6).

 

The concomitant use of docetaxel with strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, clarithromycin,indinavir, nefazodone, nelfinavir, ritonavir, saquinavir, telithromycin and voriconazole) should be avoided (see section 4.5).

 

Ethanol

Docadex contains 400 mg ethanol per ml concentrate. Harmful for those suffering from alcoholism.

To be taken into account in pregnant or breast-feeding women, children and high-risk groups such as patients with liver disease or epilepsy.

 

The amount of alcohol in this medicinal product may alter the effects of other medicinal products.

The amount of alcohol in this medicinal product may impair the patient’s ability to drive of use machines.

Additional cautions for use in adjuvant treatment of breast cancer

 

Complicated neutropenia

For patients who experience complicated neutropenia (prolonged neutropenia, febrile neutropenia, or infection), G-CSF and dose reduction should be considered (see section 4.2).

 

Gastrointestinal reactions

Symptoms such as early abdominal pain and tenderness, fever, diarrhea, with or without neutropenia, may be early manifestations of serious gastrointestinal toxicity and should be evaluated and treated promptly.

 

Congestive heart failure (CHF)

Patients should be monitored for symptoms of congestive heart failure during therapy and during the follow up period. In patients treated with the TAC regimen for node positive breast cancer, the risk of CHF has been shown to be higher during the first year after treatment (see sections 4.8 and 5.1).

 

Leukemia

In the docetaxel, doxorubicin, and cyclophosphamide (TAC) treated patients, the risk of delayed myelodysplasia or myeloid leukemia requires hematological follow-up.

 

Patients with 4+ nodes

As the benefit observed in patient with 4+ nodes was not statistically significant on disease-free survival (DFS) andoverall survival (OS), the positive benefit/risk ratio for TAC in patients with 4+ nodes was not fully demonstrated at the final analysis (see section 5.1).

 

Elderly patients

There are limited data available in patients > 70 years of age on docetaxel use in combination with doxorubicin and cyclophosphamide.

 

Of the 333 patients treated with docetaxel every three weeks in a prostate cancer study, 209 patients were 65 years of age or greater and 68 patients were older than 75 years. In patients treated with docetaxel every three weeks, the incidence of related nail changes occurred at a rate ≥ 10% higher in patients who were 65 years of age or greater compared to younger patients. The incidence of related fever, diarrhea, anorexia, and peripheral edema occurred at rates ≥ 10% higher in patients who were 75 years of age or greater versus less than 65 years.

 

Among the 300 (221 patients in the phase III part of the study and 79 patients in the phase II part) patients treated withdocetaxel in combination with cisplatin and 5-fluorouracil in the gastric cancer study, 74 were 65 years of age or older and 4 patients were 75 years of age or older. The incidence of serious adverse events was higher in the elderly patients compared to younger patients. The incidence of the following adverse events (all grades): lethargy, stomatitis, neutropenic infection occurred at rates ≥ 10% higher in patients who were 65 years of age or older compared to younger patients.

Elderly patients treated with TCF should be closely monitored.

 

During the post marketing experience a high number of delayed infusion site adverse reactions were reported for docetaxel, concentrate for solution for infusion. Although the mechanism of these reactions is not known at present it was observed that they occur close to the infusion site, several days of the last docetaxel cycle and have a “burn-like” appearance. In some cases, vesicles and vein hyperpigmentation were reported. No correlation with docetaxel cycle number was noted and re-occurrence was not always seen with re-exposure. In most of the cases the patients recovered or were recovering at the time of reporting.

In vitro studies have shown that the metabolism of docetaxel may be modified by the concomitant administration ofcompounds which induce, inhibit or are metabolized by (and thus may inhibit the enzyme competitively) cytochrome P450-3A such as cyclosporine, ketoconazole and erythromycin. As a result, caution should be exercised when treating patients with these medicinal products as concomitant therapy since there is a potential for a significant interaction.

 

In case of combination with CYP3A4 inhibitors, the occurrence of docetaxel adverse reactions may increase, as a result of reduced metabolism. If the concomitant use of a strong CYP3A4 inhibitor (e.g., ketoconazole, itraconazole, clarithromycin, indinavir, nefazodone, nelfinavir, ritonavir, saquinavir, telithromycin and voriconazole) cannot be avoided, a close clinical surveillance is warranted and a dose- adjustment of docetaxel may be suitable during the treatment with the strong CYP3A4 inhibitor (see section

4.4). In a pharmacokinetic study with 7 patients, the co-administration of docetaxel with the strong CYP3A4 inhibitor ketoconazole leads to a significant decrease in docetaxel clearance by 49%.

Docetaxel pharmacokinetics in the presence of prednisone was studied in patients with metastatic prostate cancer.Docetaxel is metabolized by CYP3A4 and prednisone is known to induce CYP3A4. No statistically significant effect of prednisone on the pharmacokinetics of docetaxel was observed.

 

Docetaxel is highly protein bound (> 95%). Although the possible in vivo interaction of docetaxel with concomitantlyadministered medication has not been investigated formally, in vitro interactions with tightly protein-bound agents such as erythromycin, diphenhydramine, propranolol, propafenone, phenytoin, salicylate,sulfamethoxazole and sodium valproate did not affect protein binding of docetaxel. In addition, dexamethasone did not affect protein binding of docetaxel. Docetaxel did not influence the binding of digitoxin.

 

The pharmacokinetics of docetaxel, doxorubicin and cyclophosphamide were not influenced by their coadministration. Limited data from a single uncontrolled study were suggestive of an interaction between docetaxel and carboplatin.When combined to docetaxel, the clearance of carboplatin was about 50% higher than values previously reported for carboplatin monotherapy.

 

Docadex contains 400 mg ethanol per ml concentrate. In higher doses (7.5 ml concentrate (150 mg) contains 3 g ethanol) the amount of alcohol may alter the effects of other medicines.

Pregnancy

There is no information on the use of docetaxel in pregnant women. Docetaxel has been shown to be both embryotoxic and fetotoxic in rabbits and rats, and to reduce fertility in rats. As with other cytotoxic medicinal products, docetaxel may cause fetal harm when administered to pregnant women. Therefore, docetaxel must not be used during pregnancy unless clearly indicated.

Women of childbearing age receiving docetaxel should be advised to avoid becoming pregnant, and to inform the treating physician immediately should this occur.

 

Breastfeeding

Docetaxel is a lipophilic substance, but it is not known whether it is excreted in human milk. Consequently, because of the potential for adverse reactions in nursing infants, breast feeding must be discontinued for the duration of docetaxel therapy.

 

Contraception in males and females

An effective method of contraception should be used during treatment.

 

Fertility

In non-clinical studies, docetaxel has genotoxic effects and may alter male fertility (see section 5.3). Therefore, men being treated with docetaxel are advised not to father a child during and up to 6 months after treatment and to seek advice on conservation of sperm prior to treatment.

No studies on the effects on the ability to drive and use machines have been performed.

Docadex contains 400 mg ethanol per ml concentrate.

In higher doses (7.5 ml concentrate (150 mg docetaxel) contains3 g ethanol) the amount of alcohol may impair the ability to drive or use machines.

Summary of the safety profile for all indications

 

The adverse reactions considered to be possibly or probably related to the administration of docetaxel have been obtained in:

• 1312 and 121 patients who received 100 mg/m² and 75 mg/m² of docetaxel as a single agent respectively
• 258 patients who received docetaxel in combination with doxorubicin 406 patients who received docetaxel in combination with cisplatin
• 92 patients treated with docetaxel in combination with trastuzumab,
• 255 patients who received docetaxel in combination with capecitabine,
• 332 patients who received docetaxel in combination with prednisone or prednisolone (clinically important treatment related adverse events are presented).
• 1276 patients (744 and 532 in TAX 316 and GEICAM 9805 respectively) who received docetaxel in combination with doxorubicin and cyclophosphamide (clinically important treatment related adverse events are presented).
• 300 gastric adenocarcinoma patients (221 patients in the phase III part of the study and 79 patients in the phase II part) who received docetaxel in combination with cisplatin and 5-fluorouracil (clinically important treatment related adverse events are presented).
• 174 and 251 head and neck cancer patients who received docetaxel in combination with cisplatin and 5-fluorouracil (clinically important treatment related adverse events are presented).

 

These reactions were described using the NCI Common Toxicity Criteria (grade 3 = G3; grade3-4 = G3/4; grade 4 = G4), the COSTART and the MedDRA terms. Frequencies are defined as: very common (≥ 1/10), common (≥1/100 to <1/10), uncommon (≥1/1,000 to <1/100), rare (≥ 1/10,000 to < 1/1,000), very rare (<1/10,000), not known (cannot be estimated from available data).

Within each frequency grouping, undesirable effects are presented in order of decreasing seriousness.

The most commonly reported adverse reactions of docetaxel alone are: neutropenia (which was reversible and not cumulative; the median day to nadir was 7 days and the median duration of severe neutropenia

(< 500 cells/mm³) was 7 days), anemia, alopecia, nausea, vomiting, stomatitis, diarrhea and asthenia. The severity of adverse events of docetaxel may be increased when docetaxel is given in combination with other chemotherapeutic agents.

 

For combination with trastuzumab, adverse events (all grades) reported in ≥ 10% are displayed. There was an increased incidence of SAEs (40% vs. 31%) and Grade 4 AEs (34% vs. 23%) in the trastuzumab combination arm compared to docetaxel monotherapy.

 

For combination with capecitabine, the most frequent treatment-related undesirable effects (≥ 5%) reported in a phaseIII study in breast cancer patients failing anthracycline treatment are presented (see capecitabine summary of product characteristics).

 

The following adverse reactions are frequently observed with docetaxel:

 

Nervous system disorders

The development of severe peripheral neurotoxicity requires a reduction of dose (see sections 4.2 and 4.4). Mild to moderate neuro-sensory signs are characterized by paresthesia, dysesthesia or pain including burning. Neuro-motor events are mainly characterized by weakness.

 

Skin and subcutaneous tissue disorders

Reversible cutaneous reactions have been observed and were generally considered as mild to moderate. Reactions were characterized by a rash including localized eruptions mainly on the feet and hands (including severe hand andfoot syndrome), but also on the arms, face or thorax, and frequently associated with pruritus. Eruptions generallyoccurred within one week after the docetaxel infusion. Less frequently, severe symptoms such as eruptions followed by desquamation which rarely lead to interruption or discontinuation of docetaxel treatment were reported (see sections 4.2 and 4.4). Severe nail disorders are characterized by hypo- or hyperpigmentation and sometimes pain and onycholysis.

 

General disorders and administration site conditions

Infusion site reactions were generally mild and consisted of hyper pigmentation, inflammation, redness or dryness of the skin, phlebitis or extravasation and swelling of the vein. Fluid retention includes events such as peripheral edema and less frequently pleural effusion, pericardial effusion, ascites, and weight gain. The peripheral edema usually starts at the lower extremities and may become generalized with a weight gain of 3 kg or more. Fluid retention is cumulative in incidence and severity (see section 4.4).

Immune system disorders

Hypersensitivity reactions have generally occurred within a few minutes following the start of the infusion ofdocetaxel and were usually mild to moderate. The most frequently reported symptoms were flushing, rash with or without pruritus, chest tightness, back pain, dyspnea and fever or chills. Severe reactions were characterized by hypotension and/or bronchospasm or generalized rash/erythema (see section 4.4).

Rare: bleeding episodes associated with grade 3/4 thrombocytopenia

 

Nervous system disorders

Reversibility data are available among 35.3% of patients who developed neurotoxicity following docetaxel treatment at 100 mg/m² as single agent. The events were spontaneously reversible within 3 months.

 

Skin and subcutaneous tissue disorders

Very rare: one case of alopecia non-reversible at the end of the study. 73% of the cutaneous reactions were reversible within 21 days.

 

General disorders and administration site conditions

The median cumulative dose to treatment discontinuation was more than 1,000 mg/m² and the median time to fluid retention reversibility was 16.4 weeks (range 0 to 42 weeks). The onset of moderate and severe retention is delayed(median cumulative dose: 818.9 mg/m²) in patients with premedication compared with patients without premedication (median cumulative dose: 489.7 mg/m²); however, it has been reported in some patients during the early courses of therapy.

Description of selected adverse reactions in breast cancer for docetaxel 100 mg/m² in combination with trastuzumab

 

Cardiac disorders

Symptomatic cardiac failure was reported in 2.2% of the patients who received docetaxel plus trastuzumab comparedto 0% of patients given docetaxel alone. In the docetaxel plus trastuzumab arm, 64% had received a prior anthracycline as adjuvant therapy compared with 55% in the docetaxel arm alone.

 

Blood and lymphatic system disorders

Very common: Hematological toxicity was increased in patients receiving trastuzumab and docetaxel, compared withdocetaxel alone (32% grade 3/4 neutropenia versus 22%, using NCI-CTC criteria). Note that this is likely to be an underestimate since docetaxel alone at a dose of 100 mg/m² is known to result in neutropenia in 97% of patients, 76% grade 4, based on nadir blood counts. The incidence of febrile neutropenia/neutropenic sepsis was also increased in patients treated with Herceptin plus docetaxel (23% versus 17% for patients treated with docetaxel alone).

Description of selected adverse reactions for adjuvant therapy with docetaxel 75 mg/m² in combination with doxorubicin and cyclophosphamide in patients with node-positive (TAX 316) and node-negative (GEICAM 9805) breast cancer

 

Cardiac disorders

In study TAX316, 26 patients (3.5%) in the TAC arm and 17 patients (2.3%) in the FAC arm experienced congestive heart failure. All except one patient in each arm were diagnosed with CHF more than 30 days after the treatment period. Two patients in the TAC arm and 4 patients in the FAC arm died because of cardiac failure.

In GEICAM 9805 study, 3 patients (0.6 %) in TAC arm and 3 patients (0.6 %) in FAC arm developed congestive heart failure during the follow-up period. One patient in TAC arm died because of dilated cardiomyopathy.

 

Nervous system disorders

Peripheral sensory neuropathy was observed to be ongoing during follow-up in10 patients out of the 84 patients with peripheral sensory neuropathy at the end of the chemotherapy in the node positive breast cancer study (TAX316).

 

Skin and subcutaneous tissue disorders

In study TAX316, alopecia persisting into the follow-up period after the end of chemotherapy was reported in 687 of 744 TAC patients and 645 of 736 FAC patients. At the end of the follow-up period (actual median follow-up time of 96 months), alopecia was observed to be ongoing in 29 TAC patients (3.9%) and 16 FAC patients (2.2%).

In GEICAM 9805 study, alopecia persisted into the follow-up period (median follow-up time of 10 years and 5months) and was observed to be ongoing in 49 patients (9.2 %) in TAC arm and 35 patients (6.7 %) in FAC arm.Alopecia related to study drug started or worsened during the follow-up period in 42 patients (7.9

%) in TAC arm and 30 patients (5.8 %) in FAC arm.

 

General disorders and administration site conditions

In study TAX316, peripheral edema was observed to be ongoing in 19 patients out of the 119 patients with peripheral edema in the TAC arm and 4 patients out of the 23 patients with peripheral edema in the FAC arm. In study GEICAM 9805, lymphoedema was observed to be ongoing in 4 of the 5 patients in TAC arm and in 1 ofthe 2 patients in FAC arm at the end of the chemotherapy, and did not resolve during the follow- up period (median follow-up time of 10 years and 5 months). Asthenia persisted into the follow-up period (median follow-up time of 10 years and 5 months) and was observed to be ongoing in 12 patients (2.3 %) in TAC arm and 4 patients (0.8 %) in FAC arm.

 

Reproductive system and breast disorders

Amenorrhea was observed to be ongoing during follow-up in 121 patients out of the 202 patients with amenorrhea at the end of the chemotherapy in study TAX316.

In GEICAM 9805 study, amenorrhea persisted into the follow-up period (median follow-up time of 10 years and 5months) and was observed to be ongoing in 18 patients (3.4 %) in TAC arm and 5 patients (1.0

%) in FAC arm.

 

Acute leukemia / Myelodysplastic syndrome

After 10 years of follow up in study TAX316, acute leukemia was reported in 4 of 744 TAC patients and in 1 of 736 FAC patients. Myelodysplastic syndrome was reported in 2 of 744 TAC patients and in 1 of 736 FAC patients.

After 10 years of follow-up in GEICAM 9805 study, acute leukemia occurred in 1 of 532 (0.2%) patients in TAC arm. No cases were reported in patients in FAC arm. No patient was diagnosed with myelodysplastic syndrome in either treatment groups.

There were a few reports of overdose. There is no known antidote for docetaxel overdose. In case of overdose, the patient should be kept in a specialized unit and vital functions closely monitored. In cases of overdose, exacerbation of adverse events may be expected. The primary anticipated complications of overdose would consist of bone marrowsuppression, peripheral neurotoxicity and mucositis. Patients should receive therapeutic G-CSF as soon as possible after discovery of overdose. Other appropriate symptomatic measures should be taken, as needed.

Pharmacotherapeutic group: Antineoplastic agents, ATC Code: L01CD 02

 

Preclinical data

 

Mechanism of action

 

Docetaxel is an antineoplastic agent which acts by promoting the assembly of tubulin into stable microtubules andinhibits their disassembly which leads to a marked decrease of free tubulin. The binding of docetaxel to microtubules does not alter the number of protofilaments.

 

Docetaxel has been shown in vitro to disrupt the microtubular network in cells which is essential for vital mitotic and interphase cellular functions.

 

Pharmacodynamic effects

 

Docetaxel was found to be cytotoxic in vitro against various murine and human tumor cell lines and against freshlyexcised human tumor cells in clonogenic assays. Docetaxel achieves high intracellular concentrations with a long cell residence time. In addition, docetaxel was found to be active on some but not all cell lines over expressing the p-glycoprotein which is encoded by the multidrug resistance gene. In vivo, docetaxel is schedule independent and has a broad spectrum of experimental antitumor activity against advanced murine and human grafted tumors.

Docetaxel in combination with doxorubicin and cyclophosphamide: adjuvant therapy

 

Patients with operable node-positive breast cancer (TAX 316)

 

Data from a multicenter open label randomized study support the use of docetaxel for the adjuvant treatment of patientswith operable node-positive breast cancer and KPS ≥ 80%, between 18 and 70 years of age. After stratification according to the number of positive lymph nodes (1-3, 4+), 1491 patients were randomized to receive either docetaxel 75 mg/m² administered 1-hour after doxorubicin 50 mg/m² and cyclophosphamide 500 mg/m² (TAC arm), or doxorubicin 50 mg/m² followed by fluorouracil 500 mg/m² and cyclophosphamide 500 mg/m² (FAC arm). Both regimens were administered once every 3 weeks for 6 cycles. Docetaxel was administered as a 1-hour infusion, all other medicinal products were given as intravenous bolus on day one. G-CSF was administered as secondary prophylaxis to patients who experienced complicated neutropenia (febrile neutropenia, prolonged neutropenia, or infection). Patients on the TAC arm received antibiotic prophylaxis with ciprofloxacin 500 mg orally twice daily for 10 days starting on day 5 of each cycle, or equivalent. In both arms, after the last cycle of chemotherapy, patients with positive estrogen and/or progesterone receptors received tamoxifen 20 mg daily for up to 5 years. Adjuvant radiation therapy was prescribed according to guidelines in place at participating institutions and was given to 69% of patients who received TAC and 72% of patients who received FAC. Two interims analyses and one final analysis were performed. The first interim analysis was planned 3 years after the date when half of study enrollment was done. Thesecond interim analysis was done after 400 DFS events had been recorded overall, which led to a median follow-up of 55 months. The final analysis was performed when all patients had reached their 10-year follow-up visit (unless they had a DFS event or were lost to follow- up before). Disease-free survival (DFS) was the primary efficacy endpoint and Overall survival (OS) was the secondary efficacy endpoint.

 

A final analysis was performed with an actual median follow up of 96 months. Significantly longer disease- freesurvival for the TAC arm compared to the FAC arm was demonstrated. Incidence of relapses at 10 years was reduced in patients receiving TAC compared to those who received FAC (39% versus 45%, respectively) i.e. an absolute risk reduction by 6% (p=0.0043). Overall survival at 10 years was also significantly increased with TAC compared to FAC (76% versus 69%, respectively) i.e. an absolute reduction of the risk of death by 7% (p = 0.002). As the benefit observed in patients with 4+ nodes were not statistically significant on DFS and OS, the positive benefit/risk ratio for TAC in patients with 4+ nodes was not fully demonstrated at the final analysis. Overall, the study results demonstrate apositive benefit risk ratio for TAC compared to FAC. TAC-treated patient subsets according to prospectively defined major prognostic factors were analyzed.

Patients with operable node-negative breast cancer eligible to receive chemotherapy (GEICAM 9805)

 

Data from a multicenter open label randomized trial support the use of docetaxel for the adjuvant treatment of patients with operable node-negative breast cancer eligible to receive chemotherapy. 1060 patients were randomized to receive either docetaxel 75 mg/m² administered 1-hour after doxorubicin 50 mg/m² and cyclophosphamide 500 mg/m² (539patients in TAC arm), or doxorubicin 50 mg/m² followed by fluorouracil 500 mg/m² and cyclophosphamide 500 mg/m²(521 patients in FAC arm), as adjuvant treatment of operable node-negative breast cancer patients with high risk of relapse according to 1998 St. Gallen criteria (tumor size >2 cm and/or negative ER and PR and/or high histological/nuclear grade (grade 2 to 3) and /or age <35 years). Both regimens were administered once every 3 weeks for 6 cycles. Docetaxel was administered as a 1-hour infusion, all other drugs were given intravenously on day 1 every three weeks. Primary prophylactic G-CSF was mademandatory in TAC arm after 230 patients were randomized. The incidence of Grade 4 neutropenia, febrile neutropenia and neutropenic infection was decreased in patients who received primary G-CSF prophylaxis (see section 4.8). In both arms, after the last cycle of chemotherapy, patients with ER+ and/or PgR+ tumors received tamoxifen 20 mg once a day for up to 5 years. Adjuvant radiation therapy was administered according to guidelines in place at participating institutions and was given to 57.3% of patients who received TAC and 51.2% of patients who received FAC.

 

One primary analysis and one updated analysis were performed. The primary analysis was done when all patients had afollow-up of greater than 5 years (median follow-up time of 77 months). The updated analysis was performed when all patients had reached their 10-year (median follow up time of 10 years and 5 months) follow-up visit (unless they had a DFS event or were lost to follow-up previously). Disease-free survival (DFS) was the primary efficacy endpoint and Overall survival (OS) was the secondary efficacy endpoint.

At the median follow-up time of 77 months, significantly longer disease-free survival for the TAC arm compared to the FAC arm was demonstrated. TAC-treated patients had a 32% reduction in the risk of relapse compared to those treated with FAC (hazard ratio = 0.68, 95% CI (0.49-0.93), p = 0.01). At the median follow up time of 10 years and 5months, TAC treated patients had a 16,5% reduction in the risk of relapse compared to those treated with FAC (hazardratio = 0.84, 95% CI (0.65-1.08), p=0.1646). DFS data were not statistically significant but were still associated with a positive trend in favors of TAC.

 

At the median follow-up time of 77 months, overall survival (OS) was longer in the TAC arm with TAC- treated patients having a 24% reduction in the risk of death compared to FAC (hazard ratio = 0.76, 95% CI (0.46-1.26, p = 0.29). However, the distribution of OS was not significantly different between the 2 groups. At the median follow uptime of 10 years and 5 months, TAC-treated patients had a 9% reduction in the risk of death compared to FAC-treated patients (hazard ratio = 0.91, 95% CI (0.63-1.32)).

The survival rate was 93.7% in the TAC arm and 91.4 % in the FAC arm, at the 8-year follow-up timepoint, and 91.3 % in the TAC arm and 89 % in the FAC arm, at the 10-year follow-up timepoint.

 

The positive benefit risk ratio for TAC compared to FAC remained unchanged.

 

TAC-treated patient subsets according to prospectively defined major prognostic factors were analyzed in the primary analysis (at the median follow-up time of 77 months) (see table below):

The estimated hazard ratio was using Cox proportional hazard model with treatment group as the factor.

 

Docetaxel as single agent

Two randomized phase III comparative studies, involving a total of 326 alkylating or 392 anthracycline failuremetastatic breast cancer patients, have been performed with docetaxel at the recommended dose and regimen of 100 mg/m² every 3 weeks.

 

In alkylating-failure patients, docetaxel was compared to doxorubicin (75 mg/m² every 3 weeks). Without affecting overall survival time (docetaxel 15 months vs. doxorubicin 14 months, p=0.38) or time to progression (docetaxel 27weeks vs. doxorubicin 23 weeks, p=0.54), docetaxel increased response rate (52% vs. 37%, p=0.01) and shortened time to response (12 weeks vs. 23 weeks, p=0.007). Three docetaxel patients (2%) discontinued the treatment due to fluid retention, whereas 15 doxorubicin patients (9%) discontinued due to cardiac toxicity (three cases of fatal congestive heart failure).

 

In anthracycline-failure patients, docetaxel was compared to the combination of Mitomycin C and Vinblastine (12mg/m² every 6 weeks and 6 mg/m² every 3 weeks). Docetaxel increased response rate (33% vs. 12%, p < 0.0001), prolonged time to progression (19 weeks vs. 11 weeks, p=0.0004) and prolonged overall survival (11 months vs. 9 months, p=0.01).

 

During these two-phase III studies, the safety profile of docetaxel was consistent with the safety profile observed in phase II studies (see section 4.8).

 

An open-label, multicenter, randomized phase III study was conducted to compare docetaxel monotherapy and paclitaxel in the treatment of advanced breast cancer in patients whose previous therapy should have included ananthracycline. A total of 449 patients were randomized to receive either docetaxel monotherapy 100 mg/m² as a 1-hour infusion or paclitaxel 175 mg/m² as a 3 hour infusion. Both regimens were administered every 3 weeks.

Without affecting the primary endpoint, overall response rate (32% vs 25%, p=0.10), docetaxel prolonged median timeto progression (24.6 weeks vs 15.6 weeks; p < 0.01) and median survival (15.3 months vs 12.7 months; p=0.03).

More grade 3/4 adverse events were observed for docetaxel monotherapy (55.4%) compared to paclitaxel (23.0%).

 

Docetaxel in combination with doxorubicin

One large randomized phase III study, involving 429 previously untreated patients with metastatic disease, has been performed with doxorubicin (50 mg/m²) in combination with docetaxel (75 mg/m²) (AT arm) versus doxorubicin (60 mg/m²) in combination with cyclophosphamide (600 mg/m²) (AC arm). Both regimens were administered on day 1 every 3 weeks.

 

Time to progression (TTP) was significantly longer in the AT arm versus AC arm, p=0.0138. The median TTP was 37.3 weeks (95%CI :33.4 - 42.1) in AT arm and 31.9 weeks (95% CI: 27.4 - 36.0) in AC arm.

Overall response rate (ORR) was significantly higher in the AT arm versus AC arm, p=0.009. The ORR was 59.3% (95%CI : 52.8 - 65.9) in AT arm versus 46.5% (95%CI : 39.8 - 53.2) in AC arm.

 

In this study, AT arm showed a higher incidence of severe neutropenia (90% versus 68.6%), febrile neutropenia (33.3% versus 10%), infection (8% versus 2.4%), diarrhea (7.5% versus 1.4%), asthenia (8.5% versus 2.4%), and pain (2.8% versus 0%) than AC arm. On the other hand, AC arm showed a higher incidence of severe anemia (15.8% versus 8.5%)than AT arm, and, in addition, a higher incidence of severe cardiac toxicity: congestive heart failure (3.8% versus 2.8%), absolute LVEF decrease ≥ 20% (13.1

% versus 6.1%), absolute LVEF decrease ≥ 30% (6.2% versus 1.1%). Toxic deaths occurred in 1 patient in the AT arm (congestive heart failure) and in 4 patients in the AC arm (1 due to septic shock and 3 due to congestive heart failure). In both arms, quality of life measured by the EORTC questionnaire was comparable and stable during treatment and follow-up.

 

Docetaxel in combination with trastuzumab

Docetaxel in combination with trastuzumab was studied for the treatment of patients with metastatic breast cancer whose tumors overexpress HER2, and who previously had not received chemotherapy for metastatic disease. Onehundred eighty-six patients were randomized to receive docetaxel (100 mg/m²) with or without trastuzumab; 60% of patients received prior anthracycline based adjuvant chemotherapy. Docetaxel plus trastuzumab was efficacious in patients whether or not they had received prior adjuvant anthracyclines. The main test method used to determine HER2positivity in this pivotal study was immunohistochemistry (IHC). A minority of patients were tested using fluorescence in-situ hybridization (FISH). In this trial, 87% of patients had disease that was IHC 3+, and 95% of patients entered haddisease that was IHC 3+ and/or FISH positive. Efficacy results are summarized in the following table:

Parameter	Docetaxel plus trastuzumab1 n=92	Docetaxel1 n=94
Response rate (95% CI)	61% (50-71)	34% (25-45)
Median duration of response (months) (95% CI)	11.4 (9.2- 15.0)	5.1 (4.4- 6.2)
Median TTP (months) (95% CI)	10.6 (7.6- 12.9)	5.7 (5.0- 6.5)

Docetaxel in combination with capecitabine

Data from one multicenter, randomized, controlled phase III clinical study support the use of docetaxel in combination with capecitabine for treatment of patients with locally advanced or metastatic breast cancer after failure of cytotoxic chemotherapy, including an anthracycline. In this study, 255 patients were randomized to treatment with docetaxel (75 mg/m² as a 1 hour intravenous infusion every 3 weeks) and capecitabine (1250 mg/m² twice daily for 2 weeks followed by 1-week rest period). 256 patients were randomized to treatment with docetaxel alone (100 mg/ m² as a 1 hour intravenous infusion every 3 weeks). Survival was superior in the docetaxel +capecitabine combination arm(p=0.0126). Median survival was 442 days (docetaxel + capecitabine) vs. 352 days (docetaxel alone). The overall objective response rates in the all-randomized population (investigator assessment) were 41.6% (docetaxel + capecitabine) vs. 29.7% (docetaxel alone); p = 0.0058. Time to progressive disease was superior in the docetaxel + capecitabine combination arm (p < 0.0001). The median time to progression was 186 days (docetaxel + capecitabine) vs. 128 days (docetaxel alone).

 

Non-small cell lung cancer

 

Patients previously treated with chemotherapy with or without radiotherapy

In a phase III study, in previously treated patients, time to progression (12.3 weeks versus 7 weeks) and overallsurvival were significantly longer for docetaxel at 75 mg/m² compared to Best Supportive Care. The 1-year survival rate was also significantly longer in docetaxel (40%) versus BSC (16%). There was less use of morphinic analgesic (p < 0.01), non-morphinic analgesics (p < 0.01), other disease related medications (p=0.06) and radiotherapy (p < 0.01) in patients treated with docetaxel at 75 mg/m² compared to those with BSC.

The overall response rate was 6.8% in the evaluable patients, and the median duration of response was 26.1 weeks.

 

Docetaxel in combination with platinum agents in chemotherapy-naïve patients

In a Phase III study, 1218 patients with unresectable stage IIIB or IV NSCLC, with KPS of 70% or greater, and who did not receive previous chemotherapy for this condition, were randomized to either docetaxel (T) 75 mg/m² as a 1 hour infusion immediately followed by cisplatin (Cis) 75 mg/ m² over 30-60 minutes every 3 weeks, docetaxel 75 mg/ m² as a 1 hour infusion in combination with carboplatin (AUC 6 mg/ml•min) over 30-60 minutes every 3 weeks, or vinorelbine (V) 25 mg/ m² administered over 6-10 minutes on days 1, 8, 15, 22 followed by cisplatin 100 mg/ m²administered on day 1 of cycles repeated every 4 weeks.

Secondary end-points included change of pain, global rating of quality of life by EuroQoL-5D, Lung Cancer Symptom Scale, and changes in Karnosfky performance status. Results on these end-points were supportive of the primary end-points results.

 

For docetaxel/carboplatin combination, neither equivalent nor non-inferior efficacy could be proven compared to the reference treatment combination VCis.

 

Prostate cancer

 

The safety and efficacy of docetaxel in combination with prednisone or prednisolone in patients with hormonerefractory metastatic prostate cancer were evaluated in a randomized multicenter Phase III study. A total of 1006 patients with KPS ≥ 60 were randomized to the following treatment groups:

Docetaxel 75 mg/m² every 3 weeks for 10 cycles.

Docetaxel 30 mg/m² administered weekly for the first 5 weeks in a 6 week cycle for 5 cycles. Mitoxantrone 12 mg/m² every 3 weeks for 10 cycles.

All 3 regimens were administered in combination with prednisone or prednisolone 5 mg twice daily, continuously.

 

Patients who received docetaxel every three weeks demonstrated significantly longer overall survival compared to thosetreated with mitoxantrone. The increase in survival seen in the docetaxel weekly arm was not statistically significant compared to the mitoxantrone control arm. Efficacy endpoints for the docetaxel arms versus the control arm are summarized in the following table:

Given the fact that docetaxel every week presented a slightly better safety profile than docetaxel every 3 weeks, it is possible that certain patients may benefit from docetaxel every week.

 

No statistical differences were observed between treatment groups for Global Quality of Life.

 

Gastric adenocarcinoma

 

A multicenter, open-label, randomized study, was conducted to evaluate the safety and efficacy of docetaxel for the treatment of patients with metastatic gastric adenocarcinoma, including adenocarcinoma of the gastroesophageal junction, who had not received prior chemotherapy for metastatic disease. A total of 445 patients with KPS>70 were treated with either docetaxel (T) (75 mg/m² on day 1) in combination with cisplatin (C) (75 mg/m² on day 1) and 5-fluorouracil (F) (750 mg/m² per day for 5 days) or cisplatin (100 mg/m² on day 1) and 5-fluorouracil (1000 mg/m² per day for 5 days). The length of a treatment cycle was 3 weeks for the TCF arm and 4 weeks for the CF arm. The median number of cycles administered per patient was 6 (with a range of 1-16) for the TCF arm compared to 4 (with a range of 1-12) for the CF arm. Time to progression (TTP) was the primary endpoint. The risk reduction of progression was 32.1% and was associated with a significantly longer TTP (p=0.0004) in favor of the TCF arm. Overall survival was also significantly longer (p=0.0201) in favor of the TCF arm with a risk reduction of mortality of 22.7%.

Efficacy results are summarized in the following table:

Subgroup analyses across age, gender and race consistently favored the TCF arm compared to the CF arm.

 

A survival update analysis conducted with a median follow-up time of 41.6 months no longer showed a statisticallysignificant difference although always in favors of the TCF regimen and showed that the benefit of TCF over CF is clearly observed between 18 and 30 months of follow up.

 

Overall, quality of life (QoL) and clinical benefit results consistently indicated improvement in favor of the TCF arm. Patients treated with TCF had a longer time to 5% definitive deterioration of global health status on the QLQ-C30 questionnaire (p=0.0121) and a longer time to definitive worsening of Karnofsky performance status (p=0.0088) compared to patients treated with CF.

 

Head and neck cancer

 

Induction chemotherapy followed by radiotherapy (TAX323)

The safety and efficacy of docetaxel in the induction treatment of patients with squamous cell carcinoma of the head and neck (SCCHN) was evaluated in a phase III, multicenter, open-label, randomized trial (TAX323). In this study, 358 patients with inoperable locally advanced SCCHN, and WHO performance status 0 or 1, were randomized to one of two treatment arms. Patients on the docetaxel arm received docetaxel (T) 75 mg/m² followed by cisplatin (P) 75 mg/m² followed by 5-fluorouracil (F) 750 mg/m² per day as a continuous infusion for 5 days. This regimen was administered every three weeks for 4 cycles in case at least a minor response (≥ 25% reduction in bidimensional measured tumor size) was observed after 2 cycles. At the end of chemotherapy, with a minimal interval of 4 weeks and a maximal interval of 7 weeks, patients whose disease did not progress received radiotherapy (RT) according to institutional guidelines for 7 weeks (TPF/RT). Patients on the comparator arm received cisplatin (P) 100 mg/m² followed by 5- fluorouracil (F) 1000 mg/m² per day for 5 days. This regimen was administered every three weeks for 4 cycles in case at least a minor response (≥ 25% reduction in bidimensional measured tumor size) was observed after 2 cycles. At the end of chemotherapy, with a minimal interval of 4 weeks and a maximal interval of 7 weeks, patients whose disease did not progress received radiotherapy (RT) according to institutional guidelines for 7 weeks (PF/RT). Locoregional therapy with radiation was delivered either with a conventional fraction (1.8 Gy - 2.0 Gy once a day, 5 days per week for a total dose of 66 to 70 Gy), or accelerated/hyper fractionated regimens of radiation therapy (twice a day, with a minimum interaction interval of 6 hours, 5 days per week). A total of 70 Gy was recommended for accelerated regimens and 74 Gy for hyper fractionated schemes. Surgical resection was allowed following chemotherapy, before or after radiotherapy. Patients on the TPF arm received antibiotic prophylaxis with ciprofloxacin 500 mg orally twice daily for 10 days starting on day 5 of each cycle, or equivalent. The primary endpoint in this study, progression-free survival (PFS), was significantly longer in the TPF arm compared to the PF arm, p = 0.0042 (median PFS: 11.4 vs. 8.3 months respectively) with an overall median follow up time of 33.7 months. Median overall survival was also significantly longer in favor of the TPF arm compared to the PF arm (median OS: 18.6 vs. 14.5 months respectively) with a 28% risk reduction of mortality, p =0.0128.

Quality of life parameters

Patients treated with TPF experienced significantly less deterioration of their Global health score compared to those treated with PF (p=0.01, using the EORTC QLQ-C30 scale).

 

Clinical benefit parameters

The performance status scale, for head and neck (PSS-HN) subscales designed to measure understandability of speech,ability to eat in public, and normalcy of diet, was significantly in favor of TPF as compared to PF. Median time to first deterioration of WHO performance status was significantly longer in the TPF arm compared to PF. Pain intensity score improved during treatment in both groups

indicating adequate pain management.

 

Induction chemotherapy followed by chemoradiotherapy (TAX324)

The safety and efficacy of docetaxel in the induction treatment of patients with locally advanced squamous cellcarcinoma of the head and neck (SCCHN) was evaluated in a randomized, multicenter open-label, phase III, study (TAX324). In this study, 501 patients, with locally advanced SCCHN, and a WHO performance status of 0 or 1, were randomized to one of two arms. The study population comprised patients with technically unresectable disease, patients with low probability of surgical cure and patients aiming at organ preservation. The efficacy and safety evaluation solely addressed survival endpoints and the success of organ preservation was not formally addressed. Patients on the docetaxel arm received docetaxel (T) 75 mg/m² by intravenous infusion on day 1 followed by cisplatin (P) 100 mg/m²administered as a 30-minute to three-hour intravenous infusion, followed by the continuous intravenous infusion of 5-fluorouracil (F) 1000 mg/m²/day from day 1 to day 4. The cycles were repeated every 3 weeks for 3 cycles. All patients who did not have progressive disease were to receive chemoradiotherapy (CRT) as per protocol (TPF/CRT). Patients on the comparator arm received cisplatin (P) 100 mg/m² as a 30-minute to three-hour intravenous infusion on day 1 followed by the continuous intravenous infusion of 5-fluorouracil (F) 1000 mg/m²/day from day 1 to day 5. The cycles were repeated every 3 weeks for 3 cycles. All patients who did not have progressive disease were to receive CRT as per protocol (PF/CRT).

Patients in both treatment arms were to receive 7 weeks of CRT following induction chemotherapy with a minimum interval of 3 weeks and no later than 8 weeks after start of the last cycle (day 22 to day 56 of last cycle). Duringradiotherapy, carboplatin (AUC 1.5) was given weekly as a one-hour intravenous infusion for a maximum of 7 doses. Radiation was delivered with megavoltage equipment using once daily fractionation (2 Gy per day, 5 days per week for 7 weeks, for a total dose of 70-72 Gy). Surgery on the primary site of disease and/or neck could be considered at any time following completion of CRT. All patients on the docetaxel-containing arm of the study received prophylactic antibiotics. The primary efficacy endpoint in this study, overall survival (OS) was significantly longer (log-rank test, p = 0.0058) with the docetaxel- containing regimen compared to PF (median OS: 70.6 versus 30.1 months respectively), with a 30% risk reduction in mortality compared to PF (hazard ratio (HR) = 0.70, 95% confidence interval (CI) = 0.54-0.90) with an overall median follow up time of 41.9 months. The secondary endpoint, PFS, demonstrated a 29% risk reduction of progression or death and a 22-month improvement in median PFS (35.5 months for TPF and 13.1 for PF). This was also statistically significant with an HR of 0.71; 95% CI 0.56-0.90; log-rank test p = 0.004. Efficacy results are presented in the table below:

Pediatric population

 

The European Medicines Agency has waived the obligation to submit the results of studies with docetaxel in all subsets of the paediatric population in breast cancer, non-small cell lung cancer, prostate cancer, gastric carcinoma and head and neck cancer, not including type II and III less differentiated nasopharyngeal carcinoma (see section 4.2 for information on pediatric use).

Absorption

The pharmacokinetics of docetaxel have been evaluated in cancer patients after administration of 20-115 mg/m² in Phase I studies. The kinetic profile of docetaxel is dose independent and consistent with a three- compartmentpharmacokinetic model with half-lives for the α, β and γ phases of 4 min, 36 min and 11.1 h, respectively. The late phase is due, in part, to a relatively slow efflux of docetaxel from the peripheral compartment.

 

Distribution

Following the administration of a 100 mg/m² dose given as a one-hour infusion a mean peak plasma level of

3.7 µg/ml was obtained with a corresponding AUC of 4.6 h.µg/ml. Mean values for total body clearance and steady-state volume of distribution were 21 l/h/m² and 113 l, respectively. Inter individual variation in total body clearance was approximately 50%. Docetaxel is more than 95% bound to plasma proteins.

 

Elimination

A study of ¹⁴C-docetaxel has been conducted in three cancer patients. Docetaxel was eliminated in both the urine and fecal following cytochrome P450-mediated oxidative metabolism of the tert-butyl ester group, within seven days, the urinary and fecal excretion accounted for about 6% and 75% of the administered radioactivity, respectively. About 80% of the radioactivity recovered in fecal is excreted during the first 48 hours as one major inactive metabolite and 3 minorinactive metabolites and very low amounts of unchanged medicinal product.

 

Special populations

 

Age and gender

A population pharmacokinetic analysis has been performed with docetaxel in 577 patients. Pharmacokinetic parameters estimated by the model were very close to those estimated from Phase I studies. The pharmacokinetics of docetaxel were not altered by the age or sex of the patient.

 

Hepatic impairment

In a small number of patients (n=23) with clinical chemistry data suggestive of mild to moderate liver functionimpairment (ALT, AST ≥ 1.5 times the ULN associated with alkaline phosphatase ≥ 2.5 times the ULN), total clearance was lowered by 27% on average (see section 4.2).

 

Fluid retention

Docetaxel clearance was not modified in patients with mild to moderate fluid retention and there are no data available in patients with severe fluid retention.

 

Combination therapy

 

Doxorubicin

When used in combination, docetaxel does not influence the clearance of doxorubicin and the plasma levels of doxorubicinol (a doxorubicin metabolite). The pharmacokinetics of docetaxel, doxorubicin and cyclophosphamide were not influenced by their coadministration.

 

Capecitabine

Phase I study evaluating the effect of capecitabine on the pharmacokinetics of docetaxel and vice versa showed noeffect by capecitabine on the pharmacokinetics of docetaxel (Cmax and AUC) and no effect by docetaxel on the pharmacokinetics of a relevant capecitabine metabolite 5’-DFUR.

 

Cisplatin

Clearance of docetaxel in combination therapy with cisplatin was similar to that observed following monotherapy. Thepharmacokinetic profile of cisplatin administered shortly after docetaxel infusion is similar to that observed with cisplatin alone.

 

Cisplatin and 5-fluorouracil

The combined administration of docetaxel, cisplatin and 5-fluorouracil in 12 patients with solid tumors had no influence on the pharmacokinetics of each individual medicinal product.

 

Prednisone and dexamethasone

The effect of prednisone on the pharmacokinetics of docetaxel administered with standard dexamethasone premedication has been studied in 42 patients.

 

Prednisone

No effect of prednisone on the pharmacokinetics of docetaxel was observed.

The carcinogenic potential of docetaxel has not been studied.

 

Docetaxel has been shown to be mutagenic in the in vitro micronucleus and chromosome aberration test in CHO-K1cells and in the in vivo micronucleus test in the mouse. However, it did not induce mutagenicity in the Ames test or the CHO/HGPRT gene mutation assay. These results are consistent with the pharmacological activity of docetaxel.

 

Undesirable effects on the testis observed in rodent toxicity studies suggest that docetaxel may impair male fertility.

This medicinal product must not be mixed with other medicinal products except those mentioned in 6.6.

Unopened vial: 24 months. After opening of the vial: Each vial is for single use and should be used immediately after opening. If not used immediately, in-use storage times and conditions are the responsibility of the user. Once added to the infusion bag: From a microbiological point of view, reconstitution/dilution must take place in controlled and aseptic conditions and the medicinal product should be used immediately. If not used immediately, in-use storage times and conditions are the responsibility of the user. Once added as recommended into the infusion bag, the docetaxel infusion solution, if stored below 25°C, in non-PVC bags, is stable for 8 hours. It should be used within 8 hours (including the one hour infusion intravenous administration). In addition, physical and chemical in-use stability of the infusion solution prepared as recommended has been demonstrated for 3 days when stored between 2 to 8°C protected from light. Docetaxel infusion solution is supersaturated, therefore may crystallize over time. If crystals appear, the solution must no longer be used and shall be discarded.

Store below 30°C.

Store in the original package in order to protect from light. Do not refrigerate or freeze.

For storage conditions after opening of the vials and of the diluted medicinal product, see section 6.3.

Docadex is an antineoplastic agent and, as with other potentially toxic compounds, caution should be exercised when handling it and preparing Docadex solutions. Cytotoxic agents should be prepared for administration only by personnel who have been trained in the safe handling of such preparations. Refer to local cytotoxic guidelines before commencing. The use of gloves is recommended. If Docadex concentrate or infusion solution should come into contact with skin, wash immediately and thoroughly with soap and water. If Docadex concentrate or infusion solution shouldcome into contact with mucous membranes, wash immediately and thoroughly with water.

 

Preparation of the solution for infusion

More than one vial of Docadex 20 mg/ml concentrate for solution for infusion may be necessary to obtain the required dose for individual patients. Based on the required dose for the patient expressed in mg, aseptically withdraw thecorresponding volume of 20 mg/ml docetaxel from the appropriate number of vials using graduated syringes fitted with a needle. For example, a dose of 140 mg docetaxel would require 7 ml of Docadex 20 mg/ml concentrate for solution for infusion.

 

For doses below 192 mg of docetaxel, inject the required volume of Docetaxel 20 mg/ml concentrate for solution for infusion into a 250 ml infusion bag or bottle containing either 250 ml of 50 mg/ml (5%) glucose solution for infusion or 9 mg/ml (0.9%) sodium chloride solution for infusion. For doses exceeding 192 mg of docetaxel more than 250 ml of the infusion solution is required, as the maximum concentration of docetaxel is 0.74 mg per ml of infusion solution.

 

Mix the infusion bag or bottle manually using a rocking motion. The diluted solution should be used within 8 hoursand should be aseptically administered as a 1-hour infusion at room temperature and normal lighting conditions.

 

Administration

For instructions on administration see Section 4.2.

 

As with all parenteral products, this medicinal product should be visually inspected prior to use and solutions containing a precipitate should be discarded.

 

Any unused product or waste material should be disposed of in accordance with local requirements.
