Z-Taxel Injection

Paclitaxel Injection, USP is indicated as subsequent therapy for the treatment of advanced carcinoma of the ovary. As first-line therapy, Paclitaxel Injection, USP is indicated in combination with cisplatin. Paclitaxel Injection, USP is indicated for the adjuvant treatment of node-positive breast cancer administered sequentially to standard doxorubicin-containing combination chemotherapy. In the clinical trial, there was an overall favorable effect on disease-free and overall survival in the total population of patients with receptor-positive and receptor-negative tumors, but the benefit has been specifically demonstrated by available data (median follow-up 30 months) only in the patients with estrogen and progesterone receptor-negative tumors (see CLINICAL STUDIES, Breast Carcinoma ). Paclitaxel Injection, USP is indicated for the treatment of breast cancer after failure of combination chemotherapy for metastatic disease or relapse within 6 months of adjuvant chemotherapy. Prior therapy should have included an anthracycline unless clinically contraindicated. Paclitaxel Injection, USP, in combination with cisplatin, is indicated for the first-line treatment of non-small cell lung cancer in patients who are not candidates for potentially curative surgery and/or radiation therapy. Paclitaxel Injection, USP is indicated for the second-line treatment of AIDS-related Kaposi's sarcoma.

Boxed warning. Paclitaxel should be administered under the supervision of a physician experienced in the use of cancer chemotherapeutic agents. Appropriate management of complications is possible only when adequate diagnostic and treatment facilities are readily available. Anaphylaxis and severe hypersensitivity reactions characterized by dyspnea and hypotension requiring treatment, angioedema, and generalized urticaria have occurred in 2 to 4% of patients receiving Paclitaxel in clinical trials. Fatal reactions have occurred in patients despite premedication. All patients should be pretreated with corticosteroids, diphenhydramine, and H 2 antagonists (see DOSAGE AND ADMINISTRATION ). Patients who experience severe hypersensitivity reactions to Paclitaxel should not be rechallenged with the drug. Paclitaxel therapy should not be given to patients with solid tumors who have baseline neutrophil counts of less than 1,500 cells/mm 3 and should not be given to patients with AIDS-related Kaposi's sarcoma if the baseline neutrophil count is less than 1,000 cells/mm 3. In order to monitor the occurrence of bone marrow suppression, primarily neutropenia, which may be severe and result in infection, it is recommended that frequent peripheral blood cell counts be performed on all patients receiving Paclitaxel. All patients should be pretreated with corticosteroids, diphenhydramine, and H 2 antagonists. (see DOSAGE AND ADMINISTRATION ). Bone marrow suppression (primarily neutropenia) is dose-dependent and is the dose-limiting toxicity. Neutrophil nadirs occurred at a median of 11 days. Paclitaxel should not be administered to patients with baseline neutrophil counts of less than 1,500 cells/mm 3 (<1,000 cells/mm 3 for patients with KS). Frequent monitoring of blood counts should be instituted during Paclitaxel treatment. Patients should not be re-treated with subsequent cycles of Paclitaxel until neutrophils recover to a level >1,500 cells/mm 3 (>1,000 cells/mm 3 for patients with KS) and platelets recover to a level >100,000 cells/mm 3. Severe conduction abnormalities have been documented in <1% of patients during Paclitaxel therapy and in some cases requiring pacemaker placement. Abridged from the full prescribing information.

Pooled Analysis of Adverse Event Experiences from Single-Agent Studies Data in the following table are based on the experience of 812 patients (493 with ovarian carcinoma and 319 with breast carcinoma) enrolled in 10 studies who received single-agent Paclitaxel Injection. Two hundred and seventy-five patients were treated in 8, Phase 2 studies with Paclitaxel doses ranging from 135 to 300 mg/m 2 administered over 24 hours (in 4 of these studies, G-CSF was administered as hematopoietic support). Three hundred and one patients were treated in the randomized Phase 3 ovarian carcinoma study which compared 2 doses (135 or 175 mg/m 2 ) and 2 schedules (3 or 24 hours) of Paclitaxel. Two hundred and thirty-six patients with breast carcinoma received Paclitaxel (135 or 175 mg/m 2 ) administered over 3 hours in a controlled study. TABLE 10.

None of the observed toxicities were clearly influenced by age. Disease-Specific Adverse Event Experiences First-Line Ovary in Combination For the 1,084 patients who were evaluable for safety in the Phase 3 first-line ovary combination therapy studies, TABLE 11 shows the incidence of important adverse events. For both studies, the analysis of safety was based on all courses of therapy (6 courses for the GOG- 111 study and up to 9 courses for the Intergroup study). TABLE 11.
