Clinical Trials Experience
Because clinical trials are conducted under varying designs and in different patient populations, the adverse reaction rates reported in one clinical trial may not be easily compared to those rates reported in another clinical trial, and may not reflect the rates actually observed in clinical practice.
Single Agent
The data below reflect exposure to NAVELBINE as a single agent administered at a dose of 30 mg/m2 on a weekly basis to 365 patients enrolled in 3 controlled studies for metastatic NSCLC and advanced breast cancer. The population included 143 previously untreated metastatic NSCLC patients (Study 3) who received a median of 8 doses of NAVELBINE. The patients were aged 32 to 79 (median 61 years), 71% were male, 91% Caucasian, 48% had adenocarcinoma histology. The data also reflect exposure to NAVELBINE in 222 patients with previously treated advanced breast cancer who received a median of 10 doses of NAVELBINE. NAVELBINE is not indicated for the treatment of breast cancer.
Selected adverse reactions reported in these studies are provided in Tables 1 and 2. The most common adverse reactions (≥ 20%) of single agent NAVELBINE were leukopenia, neutropenia, anemia, Aspartate aminotransferase (AST) elevation, nausea, vomiting, constipation, asthenia, injection site reaction, and peripheral neuropathy. The most common (≥ 5%) Grade 3 or 4 adverse reactions were neutropenia, leukopenia, anemia, increased total bilirubin, AST elevation, injection site reaction and asthenia. Approximately 49% of NSCLC patients treated with Navelbine experienced at least one dose reduction due to an adverse reaction. Thirteen percent of patients discontinued NAVELBINE due to adverse reactions. The most frequent adverse reactions leading to NAVELBINE discontinuation were asthenia, dyspnea, nausea, constipation, anorexia, myasthenia and fever.

‡ Incidence of paresthesia plus hypesthesia.
Myelosuppression: In clinical trials, Grade 3-4 neutropenia, anemia, and thrombocytopenia occurred in 69%, 9% and 1%, respectively of patients receiving single-agent NAVELBINE. Neutropenia is the major dose-limiting toxicity.
Neurotoxicity: neurotoxicity was most commonly manifested as constipation, paresthesia, hypersthesia, and hyporeflexia. Grade 3 and 4 neuropathy was observed in 1% of the patients receiving single-agent NAVELBINE.
Injection site reactions: Injection site reactions, including erythema, pain at injection site, and vein discoloration, occurred in approximately one third of patients; 5% were severe. Phlebitis (chemical phlebitis) along the vein proximal to the site of injection was reported in 10% of patients.
Cardiovascular toxicity: Chest pain occurred in 5% of patients; myocardial infarction occurred in less than 0.1% of patients.
Pulmonary Toxicity and Respiratory Failure: Dyspnea (shortness of breath) was reported in 3% of patients; it was severe in 2%. Interstitial pulmonary changes were documented.
Other: Hemorrhagic cystitis and the syndrome of inappropriate ADH secretion were each reported in <1% of patients.
In Combination with Cisplatin
Table 3 presents the incidence of selected adverse reactions, occurring in ≥ 10% of NAVELBINE treated patients reported in a randomized trial comparing the combination of NAVELBINE 25 mg/m2 administered every week of each 28-day cycle and cisplatin 100 mg/m2 administered on day 1 of each 28-day cycle versus cisplatin alone at the same dose and schedule in patients with previously untreated NSCLC (Study 1).
Patients randomized to NAVELBINE plus cisplatin received a median of 3 cycles of treatment and those randomized to cisplatin alone received a median of 2 cycles of treatment. Thirty-Five percent of the eligible patients in the combination arm required treatment discontinuation due to an adverse reaction compared to 19% in the cisplatin alone arm. The incidence of Grade 3 and 4 neutropenia was significantly higher in the NAVELBINE plus cisplatin arm (82%) compared to the cisplatin alone arm (5%). Four patients in the NAVELBINE plus cisplatin arm died of neutropenic sepsis. Seven additional deaths were reported in the combination arm: 2 from cardiac ischemia, 1 cerebrovascular accident, 1 multisystem failure due to an overdose of NAVELBINE, and 3 from febrile neutropenia.

†Categorical toxicity grade not specified
Table 4 presents the incidence of selected adverse reactions, occurring in ≥ 10% of NAVELBINE treated patients reported in a randomized trial of NAVELBINE plus cisplatin, vindesine plus cisplatin and NAVELBINE alone in patients with stage III or IV NSCLC who had not received prior chemotherapy. A total of 604 patients received either NAVELBINE 30 mg/m2 every week plus cisplatin 120 mg/m2 on Day 1 and Day 29, then every 6 weeks thereafter (N=207), vindesine 3 mg/m2 for 6 weeks, then every other week thereafter plus cisplatin 120 mg/m2 on Days 1 and Day 29, then every 6 weeks thereafter (N=193) or NAVELBINE 30mg/m2 every week (N=204).
Patients randomized to NAVELBINE plus cisplatin received a median of 15 weeks of treatment, vindesine plus cisplatin 12 weeks and NAVELBINE received 13 weeks. Study discontinuation due to an adverse reaction was required in 27, 22 and 10% of the patients randomized to NAVELBINE plus cisplatin, vindesine plus cisplatin and cisplatin alone arms, respectively. Grade 3 and 4 neutropenia was significantly greater in the NAVELBINE plus cisplatin arm (78%) compared to vindesine plus cisplatin (48%) and NAVELBINE alone (53%). Neurotoxicity, including peripheral neuropathy and constipation was reported in 44% (Grades 3-4, 7%) of the patients receiving NAVELBINE plus cisplatin, 58% (Grades 3-4, 17%) of the patients receiving vindesine and cisplatin and 44% (Grades 3-4, 8.5%) of the patients receiving NAVELBINE alone.

Nervous system disorders: loss of deep tendon reflexes, muscular weakness, gait disturbance, headache
Ear and labyrinth disorders: vestibular disorder, hearing impaired
