Kapecitabin Zentiva description

sponsored

Kapecitabin Zentiva is an orally-administered chemotherapeutic agent used in the treatment of metastatic breast and colorectal cancers. Kapecitabin Zentiva is a prodrug, that is enzymatically converted to fluorouracil (antimetabolite) in the tumor, where it inhibits DNA synthesis and slows growth of tumor tissue.

Kapecitabin Zentiva dosage

Standard

Dosage: Monotherapy: Colon, Colorectal and Breast Cancer:The recommended monotherapy starting dose of Kapecitabin Zentiva is 1250 mg/m2 administered twice daily (morning and evening; equivalent to 2500 mg/m2 total daily dose) for 2 weeks followed by a 7-day rest period.

Combination Therapy: Breast Cancer:In combination with docetaxel, the recommended starting dose of Kapecitabin Zentiva is 1250 mg/m2 twice daily for 2 weeks followed by a 7-day rest period, combined with docetaxel at 75 mg/m2 as a 1 hour intravenous infusion every 3 weeks. Premedication, according to the docetaxel labeling, should be started prior to docetaxel administration for patients receiving the Kapecitabin Zentiva plus docetaxel combination.

Colon, Colorectal, Gastric and Oesophagogastric Cancer:In combination treatment (except with irinotecan), the recommended starting dose of Kapecitabin Zentiva is 800 to 1000 mg/m2 administered twice daily for 2 weeks followed by a 7-day rest period, or 625 mg/m2 twice daily when administered continuously. For combination with irinotecan (XELIRI), the recommended starting dose of Kapecitabin Zentiva is 800 mg/m2 administered twice daily for 2 weeks followed by a 7-day rest period in combination with irinotecan 200 mg/m2 on day 1 of each three week cycle.

The inclusion of bevacizumab in a combination regimen has no effect on the starting dose of Kapecitabin Zentiva. Adjuvant treatment in patients with stage III colon cancer is recommended for a total of 6 months.

Premedication to maintain adequate hydration and anti-emesis according to the cisplatin and oxaliplatin product information should be started prior to cisplatin administration for patients receiving the Kapecitabin Zentiva plus cisplatin or oxaliplatin combination.

Kapecitabin Zentiva dose is calculated according to body surface area. The following tables show examples of the standard and reduced dose calculations for a starting dose of Kapecitabin Zentiva of either 1250 mg/m2 or 1000 mg/m2.

Dosage Adjustments During Treatment: General: Toxicity due to Kapecitabin Zentiva administration may be managed by symptomatic treatment and/or modification of the Kapecitabin Zentiva dose (treatment interruption or dose reduction). Once the dose has been reduced it should not be increased at a later time.

For those toxicities considered by the treating physician to be unlikely to become serious or life-threatening treatment can be continued at the same dose without reduction or interruption.

Dosage modifications are not recommended for Grade 1 events. Therapy with Kapecitabin Zentiva should be interrupted if a Grade 2 or 3 adverse experience occurs. Once the adverse event has resolved or decreased in intensity to Grade 1, Kapecitabin Zentiva therapy may be restarted at full dose or as adjusted according to Table 7. If a Grade 4 experience occurs, therapy should be discontinued or interrupted until the experience has resolved or decreased to Grade 1, and therapy can then be restarted at 50% of the original dose. Patients taking Kapecitabin Zentiva should be informed of the need to interrupt treatment immediately if moderate or severe toxicity occurs. Doses of Kapecitabin Zentiva omitted for toxicity are not replaced.

Haematology: Patients with baseline neutrophil counts of <1.5 x 109/L and/or thrombocyte counts of <100 x 109/L should not be treated with Kapecitabin Zentiva. If unscheduled laboratory assessments during a treatment cycle show grade 3 or 4 haematologic toxicity, treatment with Kapecitabin Zentiva should be interrupted.

Table 7 shows the recommended dose modifications following toxicity related to Kapecitabin Zentiva:

General Combination Therapy: Dose modifications for toxicity when Kapecitabin Zentiva is used in combination with other therapies should be made according to Table 7 above for Kapecitabin Zentiva and according to the appropriate Prescribing Information for the other agent(s).

At the beginning of a treatment cycle, if a treatment delay is indicated for either Kapecitabin Zentiva or the other agent(s), then administration of all agents should be delayed until the requirements for restarting all drugs are met.

During a treatment cycle for those toxicities considered by the treating physician not to be related to Kapecitabin Zentiva, Kapecitabin Zentiva should be continued and the dose of the other agent adjusted according to the appropriate Prescribing Information.

If the other agent(s) have to be discontinued permanently, Kapecitabin Zentiva treatment can be resumed when the requirements for restarting Kapecitabin Zentiva are met.

This advice is applicable to all indications and to all special populations.

Special Dosage Instructions: Patients with Hepatic Impairment Due to Liver Metastases: In patients with mild to moderate hepatic impairment due to liver metastases, no starting dose adjustment is necessary. However, such patients should be carefully monitored. Patients with severe hepatic impairment have not been studied.

Patients with Renal Impairment:In patients with moderate renal impairment [creatinine clearance 30-50 mL/min (Cockroft and Gault)] at baseline, a dose reduction to 75% for a starting dose of 1250 mg/m2 is recommended. In patients with mild renal impairment (creatinine clearance 51-80 mL/min), no adjustment in starting dose is recommended.

Careful monitoring and prompt treatment interruption is recommended if the patient develops a Grade 2, 3, or 4 adverse event with subsequent dose adjustment as outlined in Table 7 previously. If the calculated creatinine clearance decreases during treatment to a value below 30 mL/min, Kapecitabin Zentiva should be discontinued. The dose adjustment recommendations for patients with moderate renal impairment apply both to monotherapy and combination use. For dosage calculations, see Tables 5 and 6.

Children:The safety and efficacy of Kapecitabin Zentiva in children have not been established.

Elderly: For Kapecitabin Zentiva monotherapy, no adjustment of the starting dose is needed. However, severe Grade 3 or 4 treatment-related adverse events were more frequent in patients over 80 years of age compared to younger patients.

When Kapecitabin Zentiva was used in combination with other agents, elderly patients (≥65 years) experienced more Grade 3 and Grade 4 adverse drug reactions (ADRs) and ADRs that led to discontinuation, than younger patients. Careful monitoring of elderly patients is advisable.

In Combination with Docetaxel: An increased incidence of Grade 3 or 4 treatment-related adverse events and treatment-related serious adverse events was observed in patients 60 years of age or more. For patients 60 years of age or more treated with the combination of Kapecitabin Zentiva plus docetaxel, a starting dose reduction of Kapecitabin Zentiva to 75% (950 mg/m2 twice daily) is recommended. For dosage calculations, see Table 5.

Coumarin Anticoagulants: Altered coagulation parameters and/or bleeding have been reported in patients taking Kapecitabin Zentiva concomitantly with coumarin-derivative anticoagulants eg, warfarin and phenprocoumon. These events occurred within several days and up to several months after initiating Kapecitabin Zentiva therapy and in a few cases, within 1 month after stopping Kapecitabin Zentiva. In a clinical interaction study, after a single 20-mg dose of warfarin, Kapecitabin Zentiva treatment increased the AUC of S-warfarin by 57% with a 91% increase in INR value. Patients taking coumarin-derivative anticoagulants concomitantly with Kapecitabin Zentiva should be monitored regularly for alterations in their coagulation parameters (PT or INR) and the anticoagulant dose adjusted accordingly.

Cytochrome P450 (CYP450) 2C9 Substrates: No formal drug-drug interaction studies with Kapecitabin Zentiva and other drugs known to be metabolized by the CYP450 2C9 isoenzyme have been conducted. Care should be exercised when Kapecitabin Zentiva is co-administered with these drugs.

Phenytoin: Increased phenytoin plasma concentrations have been reported during concomitant use of Kapecitabin Zentiva with phenytoin. Formal drug-drug interaction studies with phenytoin have not been conducted, but the mechanism of interaction is presumed to be inhibition of the CYP2C9 isoenzyme system by Kapecitabin Zentiva. Patients taking phenytoin concomitantly with Kapecitabin Zentiva should be regularly monitored for increased phenytoin plasma concentrations.

Drug-Food Interaction: In all clinical trials, patients were instructed to take Kapecitabin Zentiva within 30 min after a meal. Since current safety and efficacy data are based upon administration with food, it is recommended that Kapecitabin Zentiva be administered with food.

Antacid: The effect of an aluminium hydroxide and magnesium hydroxide-containing antacid on the pharmacokinetics of Kapecitabin Zentiva was investigated in cancer patients. There was a small increase in plasma concentrations of Kapecitabin Zentiva and 1 metabolite (5'DFCR); there was no effect on the 3 major metabolites (5'DFUR, 5-FU and FBAL).

Leucovorin Folinic Acid: The effect of leucovorin on the pharmacokinetics of Kapecitabin Zentiva was investigated in cancer patients. Leucovorin has no effect on the pharmacokinetics of Kapecitabin Zentiva and its metabolites. However, leucovorin has an effect on the pharmacodynamics of Kapecitabin Zentiva and its toxicity may be enhanced by leucovorin.

Sorivudine and Analogues: A clinically significant drug-drug interaction between sorivudine and 5-FU, resulting from the inhibition of dihydropyrimidine dehydrogenase by sorivudine, has been described in the literature. This interaction, which leads to increased fluoropyrimidine toxicity, is potentially fatal. Therefore, Kapecitabin Zentiva should not be administered with sorivudine or its chemically related analogues eg, brivudine. There must be at least a 4-week waiting period between the end of treatment with sorivudine or its chemically related analogues eg, brivudine and start of Kapecitabin Zentiva therapy.

Oxaliplatin: No clinically significant differences in exposure to Kapecitabin Zentiva or its metabolites, free platinum or total platinum occured when Kapecitabin Zentiva or oxaliplatin were administered in combination with or without bevacizumab.

Bevacizumab: There was no clinically significant effect of bevacizumab on the pharmacokinetic parameters of Kapecitabin Zentiva or its metabolites.

What are the possible side effects of Kapecitabin Zentiva?

Clinical Trials: Adverse drug reactions (ADRs) considered by the investigator to be possibly, probably, or remotely related to the administration of Kapecitabin Zentiva have been obtained from clinical studies conducted with Kapecitabin Zentiva monotherapy (in adjuvant therapy of colon cancer, in metastatic colorectal cancer and metastatic breast cancer), and clinical studies conducted with Kapecitabin Zentiva in combination with different chemotherapy regimens for multiple indications. ADRs are added to the appropriate category in the tables below according to the highest incidence from the pooled analysis of seven clinical trials. Within each frequency grouping ADRs are listed in descending order of seriousness. Frequencies are defined as very common ≥1/10, common ≥5/100 to <1/10 and uncommon ≥1/1000 to <1/100.

Kapecitabin Zentiva Monotherapy: Safety data of Kapecitabin Zentiva monotherapy were reported for patients who received adjuvant treatment for colon cancer and for patients who received treatment for metastatic breast cancer or metastatic colorectal cancer. The safety information includes data from a phase III trial in adjuvant colon cancer (995 patients treated with Kapecitabin Zentiva and 974 treated with i.v. 5-FU/LV) and from 4 phase II trials in female patients with breast cancer (N=319) and 3 trials (1 phase II and 2 phase III trials) in male and female patients with colorectal cancer (N=630). The safety profile of Kapecitabin Zentiva monotherapy is comparable in patients who received adjuvant treatment for colon cancer and in those who received treatment for metastatic breast cancer or metastatic colorectal cancer. The intensity of ADRs was graded according to the toxicity categories of the NCIC CTC Grading System.

Skin fissures were reported to be at least remotely related to Kapecitabin Zentiva in less than 2% of the patients in seven completed clinical trials (N=949).

The following ADRs represent known toxicities with fluoropyrimidine therapy and were reported to be at least remotely related to Kapecitabin Zentiva in less than 5% of patients in seven completed clinical trials (N=949): Gastrointestinal Disorders: Dry mouth, flatulence, ADRs related to inflammation/ulceration of mucous membranes such as esophagitis, gastritis, duodenitis, colitis, gastrointestinal hemorrhage.

Cardiac Disorders: Edema lower limb, cardiac chest pain including angina, cardiomyopathy, myocardial ischemia/infarction, cardiac failure, sudden death, tachycardia, atrial arrhythmias including atrial fibrillation, and ventricular extrasystoles.

Nervous System Disorders: Taste disturbance, insomnia, confusion, encephalopathy, and cerebellar signs such as ataxia, dysarthria, impaired balance, abnormal coordination.

Infections and Infestations: ADRs related to bone marrow depression, immune system compromise, and/or disruption of mucous membranes, such as local and fatal systemic infections (including bacterial, viral, fungal etiologies) and sepsis.

Blood and Lymphatic System Disorders: Anemia, bone marrow depression/pancytopenia.

Skin and Subcutaneous Tissue Disorders: Pruritus, localized exfoliation, skin hyperpigmentation, nail disorders, photosensitivity reactions, radiation recall syndrome.

General Disorders and Administration Site Conditions: Pain in limb, chest pain (non-cardiac).

Eye: Eye Irritation.

Respiratory: Dyspnoea, cough.

Musculoskeletal: Back pain, myalgia, arthralgia.

Psychiatric Disorders: Depression.

Hepatic failure and cholestatic hepatitis have been reported during clinical trials and post-marketing exposure. A causal relationship with Kapecitabin Zentiva treatment has not been established.

Kapecitabin Zentiva in Combination Therapy: Table 9 lists ADRs associated with the use of Kapecitabin Zentiva in combination therapy with different chemotherapy regimens in multiple indications and occurred in addition to those seen with monotherapy and/or at a higher frequency grouping. The safety profile was similar across all indications and combination regimens. These reactions occurred in ≥5% of patients treated with Kapecitabin Zentiva in combination with other chemotherapies. Adverse drug reactions are added to the appropriate category in Table 9 according to the highest incidence seen in any of the major clinical trials. Some of the adverse reactions are reactions commonly seen with chemotherapy (e.g. peripheral sensory neuropathy with docetaxel or oxaliplatin) or with bevacizumab (e.g. hypertension); however, an exacerbation by Kapecitabin Zentiva therapy cannot be excluded.

Hypersensitivity reactions (2%) and cardiac ischaemia/infarction (3%) have been reported commonly for Kapecitabin Zentiva in combination with other chemotherapy but in less than 5% of patients.

Rare or uncommon ADRs reported for Kapecitabin Zentiva in combination with other chemotherapy are consistent with the ADRs reported for Kapecitabin Zentiva monotherapy or the combination product monotherapy.

Laboratory Abnormalities: Table 10 displays laboratory abnormalities observed in 995 patients (adjuvant colon cancer) and 949 patients (metastatic breast and colorectal cancer), regardless of relationship to treatment with Kapecitabin Zentiva.

Post-Marketing: The following ADRs have been identified during post-marketing exposure:

Laboratory Abnormalities: No text.
