Myelosuppression manifested by neutropenia, anemia and thrombocytopenia occur with Maverex as a single agent and in combination with cisplatin. Neutropenia is the major dose-limiting toxicity with Maverex. Grade 3-4 neutropenia occurred in 53% of patients treated with Maverex at 30 mg/m2 per week. Dose adjustment due to myelosuppression occurred in 51% of patients (Study 2). In clinical trials with Maverex administered at 30 mg/m2 per week, neutropenia resulted in hospitalizations for pyrexia and/or sepsis in 8% of patients. Death due to sepsis occurred in 1% of patients. Neutropenia nadirs occur between 7 and 10 days after dosing with neutropenia count recovery usually occurring within the following 7 to 14 days.
Monitor complete blood counts prior to each dose of Maverex. Do not administer Maverex to patients with neutrophil counts less than 1,000 cells/mm3. Adjustments in the dosage of Maverex should be based on neutrophil counts obtained on the day of treatment.
Drug-induced liver injury manifest by elevations of aspartate aminotransferase and bilirubin can occur in patients receiving Maverex alone or in combination with cytotoxic agents. Assess hepatic function prior to initiation of Maverex and periodically during treatment. Reduce the dose of Maverex for patients who develop elevations in total bilirubin greater than 2 times upper limit of normal.
Severe and fatal paralytic ileus, constipation, intestinal obstruction, necrosis, and perforation occur with Maverex administration. Institute a prophylactic bowel regimen to mitigate potential constipation, bowel obstruction and/or paralytic ileus, considering adequate dietary fiber intake, hydration, and routine use of stool softeners.
Extravasation of Maverex can result in severe irritation, local tissue necrosis and/or thrombophlebitis. If signs or symptoms of extravasation occur, immediately stop administration of Maverex and institute recommended management procedures.
Sensory and motor neuropathies, including severe neuropathies, occur in patients receiving Maverex. Monitor patients for new or worsening signs and symptoms of neuropathy such as paresthesia, hyperesthesia, hyporeflexia and muscle weakness while receiving Maverex. Discontinue Maverex for NCI CTCAE Grade 2 or greater neuropathy
Pulmonary toxicity, including severe acute bronchospasm, interstitial pneumonitis, acute respiratory distress syndrome occurs with use of Maverex. Interstitial pneumonitis and ARDS included fatalities. The mean time to onset of interstitial pneumonitis and ARDS after Maverex administration was one week (range 3 to 8 days).
Interrupt Maverex in patients who develop unexplained dyspnea, or have any evidence of pulmonary toxicity. Permanently discontinue Maverex for confirmed interstitial pneumonitis or ARDS.
Maverex can cause fetal harm when administered to a pregnant woman. In animal reproduction studies in mice and rabbits, embryo and fetal toxicity were observed with administration of Maverex at doses approximately 0.33 and 0.18 times the human therapeutic dose, respectively. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, apprise the patient of the potential hazard to a fetus. Advise females of reproductive potential to use highly effective contraception during therapy with Maverex.
The following serious adverse reactions, which may include fatalities, are discussed in greater detail in other sections of the label:
Most common adverse reactions (incidence greater than or equal to 20%) are neutropenia, anemia, liver enzyme elevation, nausea, vomiting, asthenia, constipation, injection site reaction, and peripheral neuropathy (6.1)
To report SUSPECTED ADVERSE REACTIONS, contact Actavis at 1-800-432-8534 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
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 Maverex 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 Maverex. 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 Maverex in 222 patients with previously treated advanced breast cancer who received a median of 10 doses of Maverex. Maverex 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 (greater than or equal to 20%) of single agent Maverex were leukopenia, neutropenia, anemia, Aspartate aminotransferase (AST) elevation, nausea, vomiting, constipation, asthenia, injection site reaction, and peripheral neuropathy. The most common (greater than or equal to 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 Maverex experienced at least one dose reduction due to an adverse reaction. Thirteen percent of patients discontinued Maverex due to adverse reactions. The most frequent adverse reactions leading to Maverex discontinuation were asthenia, dyspnea, nausea, constipation, anorexia, myasthenia and fever.

Table 3 presents the incidence of selected adverse reactions, occurring in greater than or equal to 10% of Maverex treated patients reported in a randomized trial comparing the combination of Maverex 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 Maverex 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 Maverex plus cisplatin arm (82%) compared to the cisplatin alone arm (5%). Four patients in the Maverex 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 Maverex, and 3 from febrile neutropenia.

Table 4 presents the incidence of selected adverse reactions, occurring in greater than or equal to 10% of Maverex treated patients reported in a randomized trial of Maverex plus cisplatin, vindesine plus cisplatin and Maverex alone in patients with stage III or IV NSCLC who had not received prior chemotherapy. A total of 604 patients received either Maverex 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 Maverex 30mg/m2 every week (N=204).
Patients randomized to Maverex plus cisplatin received a median of 15 weeks of treatment, vindesine plus cisplatin 12 weeks and Maverex received 13 weeks. Study discontinuation due to an adverse reaction was required in 27, 22 and 10% of the patients randomized to Maverex plus cisplatin, vindesine plus cisplatin and cisplatin alone arms, respectively. Grade 3 and 4 neutropenia was significantly greater in the Maverex plus cisplatin arm (78%) compared to vindesine plus cisplatin (48%) and Maverex alone (53%). Neurotoxicity, including peripheral neuropathy and constipation was reported in 44% (Grades 3-4, 7%) of the patients receiving Maverex 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 Maverex alone.

The following adverse reactions have been identified during post-approval use of Maverex. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Infections and infestations: pneumonia
Immune system disorders: anaphylactic reaction, pruritus, urticaria, angioedema
Nervous system disorders: loss of deep tendon reflexes, muscular weakness, gait disturbance, headache
Ear and labyrinth disorders: vestibular disorder, hearing impaired
Cardiac disorders: tachycardia
Respiratory disorders: pulmonary edema
Vascular disorders: pulmonary embolism, deep vein thrombosis, hypertension, hypotension, flushing, vasodilatation
Gastrointestinal disorders: mucosal inflammation, dysphagia, pancreatitis
Skin disorders: generalized cutaneous reactions (rash)
Musculoskeletal and connective tissue disorders: jaw pain, myalgia, arthralgia
General disorders and administration site conditions: injection site rash, urticaria, blistering, sloughing of skin
Injury, poisoning and procedural complications: radiation recall phenomenon, dermatitis, esophagitis
Laboratory abnormalities: electrolyte imbalance including hyponatremia
Other: tumor pain, back pain, abdominal pain
Exercise caution in patients concurrently taking drugs known to inhibit drug metabolism by hepatic cytochrome P450 isoenzymes in the CYP3A subfamily. Concurrent administration of Maverex with an inhibitor of this metabolic pathway may cause an earlier onset and/or an increased severity of adverse reactions.
Teratogenic Effects: Pregnancy Category D
Risk Summary
Maverex can cause fetal harm when administered to a pregnant woman. In animal reproduction studies in mice and rabbits, embryo and fetal toxicity were observed with administration of Maverex at doses approximately 0.33 and 0.18 times the human therapeutic dose, respectively. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, apprise the patient of the potential hazard to a fetus.
Animal Data
In a mouse embryofetal development study, administration of a single dose of Maverex at a dose level of 9 mg/m2 or greater (approximately 0.33 times the recommended human dose based on body surface area) was embryotoxic and fetotoxic. Maverex was embryotoxic and fetotoxic to pregnant rabbits when administered every 6 days during the period of organogenesis at doses of 5.5 mg/m2 (approximately 0.18 times the recommended human dose based on body surface area) or greater. At doses that did not cause maternal toxicity in either species, Maverex administration resulted in reduced fetal weight and delayed ossification.
It is not known whether this drug is present in human milk. Because many drugs are present in human milk and because of the potential for serious adverse reactions in nursing infants from Maverex, a decision should be made whether to discontinue nursing or discontinue the drug taking into account the importance of the drug to the mother.
The safety and effectiveness of Maverex in pediatric patients have not been established. Results from a single-arm study of Maverex administered at the dose of 33.75 mg/m2 or at the dose of 30mg/m2 (for 11 patients) every week during 6 weeks followed by 2 weeks of rest was evaluated (courses of 8 weeks). Forty-six patients age 1 to 25 (median 11 years) with recurrent solid malignant tumors, including rhabdomyosarcoma or undifferentiated sarcoma (N=21 patients), neuroblastoma (N= 4 patients), and central nervous system (CNS) tumors (N=21 patients) were enrolled. The most significant grade 3 or 4 hematological adverse reactions were neutropenia (70%) and anemia (33%). The most significant grade 3 or 4 non-hematological toxicity adverse reactions were motor (15%) or cranial (13%) neuropathy, hypoxia (13%) and dyspnea (11%). Objective tumor response was observed in 2 out of 21 patients with rhabdomyosarcoma or undifferentiated sarcoma. No objective tumor response was observed in patients with CNS tumors (N=21) or neuroblastoma (N=4).
Of the 769 number of patients who received Maverex alone and Maverex in combination with Cisplatin in studies 1, 2 and 3, 247 patients were 65 years of age or older. No overall differences in safety, efficacy and pharmacokinetic parameters were observed between these patients and younger patients..
The influence of hepatic impairment on the pharmacokinetics of Maverex has not been evaluated, but the liver plays an important role in the metabolism of Maverex. Elevations of aspartate aminotransferase occur in greater than 60% of the patients receiving Maverex alone. Therefore, exercise caution in patients with hepatic impairment. Reduce the dose of Maverex for patients with bilirubin elevation.
Contraception
Females
Maverex can cause fetal harm when administered to a pregnant woman. Advise female patients of reproductive potential to use highly effective contraception during therapy with Maverex.
Males
Maverex may damage spermatozoa. Males with female sexual partners of reproductive potential should use highly effective contraception during and for 3 months after therapy with Maverex.
Fertility
Males
Based on animal findings, Maverex may cause decreased fertility in males
There is no known antidote for overdoses of Maverex. Overdoses involving quantities up to 10 times the recommended dose (30 mg/m2) have been reported. The toxicities described were consistent with those listed in the ADVERSE REACTIONS section including paralytic ileus, stomatitis, and esophagitis. Bone marrow aplasia, sepsis, and paresis have also been reported. Fatalities have occurred following overdose of Maverex. If overdosage occurs, general supportive measures together with appropriate blood transfusions, growth factors, and antibiotics should be instituted as deemed necessary by the physician.
Maverex tartrate, USP is a semi-synthetic vinca alkaloid for intravenous injection. Chemically, Maverex tartrate, USP is 3',4'-didehydro-4'-deoxy-C'-norvincaleukoblastine [R--2, 3-dihydroxybutanedioate (1:2)(tartrate)] and has the following structure:

Study 2 was a randomized, 3-arm, open-label, multicenter trial of Maverex plus cisplatin, vindesine plus cisplatin and Maverex alone for the treatment of patients with stage III or IV NSCLC who had not received prior chemotherapy. The study was conducted in Europe. A total of 612 patients were randomized 1:1:1 to receive Maverex 30 mg/m2 every week of a 6-week cycle plus cisplatin 120 mg/m2 on Day 1 and Day 29, then every 6 weeks thereafter (N=206); and 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=200) or Maverex 30mg/m2 every week of a 6-week cycle (N=206). The main efficacy outcome measure was to compare overall survival between Maverex plus cisplatin and vindesine plus cisplatin. The other efficacy outcome measure was to compare overall survival in the better of the two combination regimens to that of Maverex alone.
Patient demographics were in general similar between arms: the median age of the overall population was 60 years (range 30 to 75), 90% were male, 78% had WHO performance status of 0 or 1. Tumor characteristics were in general similar with the exception of histologic subtype of NSCLC. Adenocarcinoma was the histologic subtype in 32% of patients in the Maverex plus cisplatin arm, 40% of patients in vindesine plus cisplatin arm and 28% of patients on the Maverex alone arm. Ten percent of the patients had stage IIIA disease, 28% stage IIIB and 50% stage IV. Twelve percent of the patients had received prior surgery or radiotherapy.
The efficacy results of Study 2 are presented in Table 8.

The safety and efficacy of Maverex as a single agent was evaluated in one randomized multi-center trial.
Study 3 was a randomized, open-label clinical trial of Maverex or 5-Fluorouracil (5-FU) plus leucovorin (LV) in patients with Stage IV NSCLC who had not received prior chemotherapy A total of 211 patients were randomized 2:1 to receive Maverex 30 mg/m2 weekly of a 8-week cycle (N=143) or 5-FU 425 mg/m2 bolus intravenously plus LV 20 mg/m2 bolus intravenously daily for 5 days of a 4-weeks cycle (N=68).
Patient demographics and disease characteristics were in general similar between arms. In the overall population, the median age was 61 years (range 32 to 83), 74% were male, 88% were Caucasian, 46% had adenocarcinoma histology. Fifty percent of the patients had Karnofsky performance status greater than or equal to 90 in the Maverex arm compared to 38% in the 5-FU and LV arm.
The primary efficacy outcome of the study was overall survival. The median survival time was 30 weeks versus 22 weeks for patients receiving Maverex versus 5-FU/LV, respectively (P=0.06). Partial objective responses were observed in 11.1% (95% CI=6.2%, 17.9%) and 3.5% (95% CI=0.4%, 11.9%) of patients who received Maverex and 5-FU/LV, respectively.
