6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Myelosuppression [see Warnings and Precautions ( 5.1 )]. Myelodysplastic Syndrome and Secondary Malignancies [see Warnings and Precautions ( 5.2 )]. Pneumocystis Pneumonia [see Warnings and Precautions ( 5.3 )]. Hepatotoxicity [see Warnings and Precautions ( 5.4 )]. The most common adverse reactions (≥20% incidence) are: alopecia, fatigue, nausea, vomiting, headache, constipation, anorexia, and convulsions. (6.1) The most common Grade 3 to 4 hematologic laboratory abnormalities (≥10% incidence) in patients with anaplastic astrocytoma are: decreased lymphocytes, decreased platelets, decreased neutrophils, and decreased leukocytes.

Newly Diagnosed Glioblastoma The safety of temozolomide was evaluated in Study MK-7365-051 [see Clinical Studies ( 14.1 )]. Forty-nine percent (49%) of patients treated with temozolomide reported one or more severe or life-threatening reactions, most commonly fatigue (13%), convulsions (6%), headache (5%), and thrombocytopenia (5%). The most common adverse reactions (≥ 20%) across the cumulative temozolomide experience were alopecia, fatigue, nausea, and vomiting. Table 3 summarizes the adverse reactions in Newly Diagnosed Glioblastoma Trial. Overall, the pattern of reactions during the maintenance phase was consistent with the known safety profile of temozolomide. Table 3 Adverse Reactions (≥ 5%) in Patients Receiving Temozolomide in Newly Diagnosed Glioblastoma Trial *One patient who was randomized to radiation therapy only arm received radiation therapy and temozolomide. NOS=not otherwise specified. Note: Grade 5 (fatal) adverse reactions are included in the Grade ≥3 column.

Refractory Anaplastic Astrocytoma The safety of temozolomide was evaluated in Study MK-7365-006 [see Clinical Studies ( 14.2 )]. Myelosuppression (thrombocytopenia and neutropenia) was the dose-limiting adverse reaction. It usually occurred within the first few cycles of therapy and was not cumulative. Myelosuppression occurred late in the treatment cycle and returned to normal, on average, within 14 days of nadir counts. The median nadirs occurred at 26 days for platelets (range: 21-40 days) and 28 days for neutrophils (range: 1-44 days). Only 14% (22/158) of patients had a neutrophil nadir and 20% (32/158) of patients had a platelet nadir, which may have delayed the start of the next cycle. Less than 10% of patients required hospitalization, blood transfusion, or discontinuation of therapy due to myelosuppression. The most common adverse reactions (≥20%) were nausea, vomiting, headache, fatigue, constipation, and convulsions. Tables 4 and 5 summarize the adverse reactions and hematological laboratory abnormalities in Refractory Anaplastic Astrocytoma Trial.

In the entire safety database for which hematologic data exist (N=932), 7% (4/61) and 9.5% (6/63) of patients > 70 years experienced Grade 4 neutropenia or thrombocytopenia in the first cycle, respectively. For patients ≤ 70 years, 7% (62/871) and 5.5% (48/879) experienced Grade 4 neutropenia or thrombocytopenia in the first cycle, respectively. Pancytopenia, leukopenia, and anemia also occurred. 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of temozolomide. 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 the drug exposure. Dermatologic : Toxic epidermal necrolysis and Stevens-Johnson syndrome Immune System : Hypersensitivity reactions, including anaphylaxis. Erythema multiforme, which resolved after discontinuation of temozolomide and, in some cases, recurred upon rechallenge. Hematopoietic : Prolonged pancytopenia, which may result in aplastic anemia and fatal outcomes. Hepatobiliary : Fatal and severe hepatotoxicity, elevation of liver enzymes, hyperbilirubinemia, cholestasis, and hepatitis. Infections : Serious opportunistic infections, including some cases with fatal outcomes, with bacterial, viral (primary and reactivated), fungal, and protozoan organisms. Pulmonary : Interstitial pneumonitis, pneumonitis, alveolitis, and pulmonary fibrosis. Endocrine : Diabetes insipidus

4 CONTRAINDICATIONS Temozolomide is contraindicated in patients with a history of hypersensitivity reactions to: temozolomide or any other ingredients in temozolomide capsules; and dacarbazine, since both temozolomide and dacarbazine are metabolized to the same active metabolite 5-(3methyltriazen-1-yl)-imidazole-4-carboxamide. Reactions to temozolomide have included anaphylaxis [see Adverse Reactions ( 6.2 )]. History of hypersensitivity to temozolomide or any other ingredients in temozolomide capsules and dacarbazine.

Follow applicable special handling and disposal procedures. 1 Temozolomide capsules Administer temozolomide consistently with respect to food (fasting vs. nonfasting) [see Clinical Pharmacology ( 12.3 )] . To reduce nausea and vomiting, take temozolomide on an empty stomach or at bedtime and consider antiemetic therapy prior to and/or following temozolomide administration. Swallow temozolomide capsules whole. Do not open or chew capsules. If capsules are accidentally opened or damaged, take precautions to avoid inhalation or contact with the skin or mucous membranes . In case of powder contact, the hands should be washed.

1 INDICATIONS AND USAGE Temozolomide is an alkylating drug indicated for the treatment of adult patients with: Newly diagnosed glioblastoma concomitantly with radiotherapy and then as maintenance treatment. (1.1) Refractory anaplastic astrocytoma who have experienced disease progression on a drug regimen containing nitrosourea and procarbazine. (1.2) 1.1 Newly Diagnosed Glioblastoma Temozolomide capsules are indicated for the treatment of adult patients with newly diagnosed glioblastoma concomitantly with radiotherapy and then as maintenance treatment. 1.2 Refractory Anaplastic Astrocytoma Temozolomide capsules are indicated for the treatment of adult patients with refractory anaplastic astrocytoma who have experienced disease progression on a drug regimen containing nitrosourea and procarbazine.

10 OVERDOSAGE Dose-limiting toxicity was myelosuppression and was reported with any dose but is expected to be more severe at higher doses. An overdose of 2000 mg per day for 5 days was taken by one patient and the adverse reactions reported were pancytopenia, pyrexia, multi-organ failure, and death. There are reports of patients who have taken more than 5 days of treatment (up to 64 days), with adverse reactions reported including myelosuppression, which in some cases was severe and prolonged, and infections and resulted in death. In the event of an overdose, monitor complete blood count and provide supportive measures as necessary.

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Temozolomide is not directly active but undergoes rapid nonenzymatic conversion at physiologic pH to the reactive compound 5-(3methyltriazen-1-yl)-imidazole-4-carboxamide (MTIC). The cytotoxicity of MTIC is thought to be primarily due to alkylation of DNA. Alkylation (methylation) occurs mainly at the O 6 and N 7 positions of guanine. 12.3 Pharmacokinetics Following a single oral dose of 150 mg/m 2 , the mean C max value for temozolomide was 7.5 mcg/mL and for MTIC was 282 ng/mL. The mean AUC value for temozolomide was 23.4 mcg·hr/mL and for MTIC was 864 ng·hr/mL. Following a single 90-minute intravenous infusion of 150 mg/m 2 , the mean C max value for temozolomide was 7.3 mcg/mL and for MTIC was 276 ng/mL. The mean AUC value for temozolomide was 24.6 mcg·hr/mL and for MTIC was 891 ng·hr/mL. Temozolomide exhibits linear kinetics over the therapeutic dosing range of 75 mg/m 2 /day to 250 mg/m 2 /day. Absorption The median T max is 1 hour. Effect of Food The mean C max and AUC decreased by 32% and 9%, respectively, and median T max increased by 2-fold (from 1 hour to 2.25 hours) when temozolomide capsules were administered after a modified high-fat breakfast (587 calories comprised of 1 fried egg, 2 strips of bacon, 2 slices of toast, 2 pats of butter, and 8 oz whole milk). Distribution Temozolomide has a mean apparent volume of distribution of 0.4 L/kg (%CV=13%). The mean percent bound of drug-related total radioactivity is 15%. Elimination Clearance of temozolomide is about 5.5 L/hr/m 2 and the mean elimination half-life is 1.8 hours. Metabolism Temozolomide is spontaneously hydrolyzed at physiologic pH to the active species, MTIC and to temozolomide acid metabolite. MTIC is further hydrolyzed to 5-amino-imidazole-4-carboxamide (AIC), which is known to be an intermediate in purine and nucleic acid biosynthesis, and to methylhydrazine, which is believed to be the active alkylating species. Cytochrome P450 enzymes play only a minor role in the metabolism of temozolomide and MTIC. Relative to the AUC of temozolomide, the exposure to MTIC and AIC is 2.4% and 23%, respectively. Excretion About 38% of the administered temozolomide total radioactive dose is recovered over 7 days: 38% in urine and 0.8% in feces. The majority of the recovery of radioactivity in urine is unchanged temozolomide (6%), AIC (12%), temozolomide acid metabolite (2.3%), and unidentified polar metabolite(s) (17%). Specific Populations No clinically meaningful differences in the pharmacokinetics of temozolomide were observed based on age (range: 19 years to 78 years), gender, smoking status (smoker vs. non-smoker), creatinine clearance (CLcr) of 36 to 130 mL/min/m 2 , or mild to moderate hepatic impairment (Child Pugh class A and B). The pharmacokinetics of temozolomide has not been studied in patients with CLcr < 36 mL/min/m 2 , end-stage renal disease on dialysis, or severe hepatic impairment (Child-Pugh class C). Drug Interaction Studies Effect of Other Drugs on Temozolomide Pharmacokinetics In a multiple-dose study, administration of temozolomide capsules with ranitidine did not change the C max or AUC values for temozolomide or MTIC. A population analysis indicated that administration of valproic acid decreases the clearance of temozolomide by about 5% . A population analysis did not demonstrate any influence of coadministered dexamethasone, prochlorperazine, phenytoin, carbamazepine, ondansetron, histamine-2-receptor antagonists, or phenobarbital on the clearance of orally administered temozolomide.

13.2 Animal Toxicology and/or Pharmacology Toxicology studies in rats and dogs identified a low incidence of hemorrhage, degeneration, and necrosis of the retina at temozolomide doses equal to or greater than 125 mg/m 2 (0.63 times the human dose of 200 mg/m 2 ). These changes were most commonly seen at doses where mortality was observed.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Temozolomide is carcinogenic in rats at doses less than the maximum recommended human dose. Temozolomide induced mammary carcinomas in both males and females at doses 0.13 to 0.63 times the maximum human dose (25 mg/m 2 to 125 mg/m 2 ) when administered orally on 5 consecutive days every 28 days for 6 cycles. Temozolomide also induced fibrosarcomas of the heart, eye, seminal vesicles, salivary glands, abdominal cavity, uterus, and prostate, carcinomas of the seminal vesicles, schwannomas of the heart, optic nerve, and harderian gland, and adenomas of the skin, lung, pituitary, and thyroid at doses 0.5 times the maximum daily dose. Mammary tumors were also induced following 3 cycles of temozolomide at the maximum recommended daily dose. Temozolomide is a mutagen and a clastogen. In a reverse bacterial mutagenesis assay (Ames assay), temozolomide increased revertant frequency in the absence and presence of metabolic activation. Temozolomide was clastogenic in human lymphocytes in the presence and absence of metabolic activation. Temozolomide impairs male fertility. Temozolomide caused syncytial cells/immature sperm formation at doses of 50 mg/m 2 and 125 mg/m 2 (0.25 times and 0.63 times the human dose of 200 mg/m 2 ) in rats and dogs, respectively, and testicular atrophy in dogs at 125 mg/m 2 .

14 CLINICAL STUDIES 14.1 Newly Diagnosed Glioblastoma The efficacy of temozolomide was evaluated in Study MK-7365-051, a randomized (1:1), multicenter, open-label trial. Eligible patients were required to have newly diagnosed glioblastoma. Patients were randomized to receive either radiation therapy alone or concomitant temozolomide 75 mg/m 2 once daily starting the first day of radiation therapy and continuing until the last day of radiation therapy for 42 days (with a maximum of 49 days), followed by temozolomide 150 mg/m 2 or 200 mg/m 2 once daily on Days 1 to 5 of each 28-day cycle, starting 4 weeks after the end of radiation therapy and continuing for 6 cycles. In both arms, focal radiation therapy was delivered as 60 Gy/30 fractions and included radiation to the tumor bed or resection site with a 2- to 3-cm margin. PCP prophylaxis was required during the concomitant phase, regardless of lymphocyte count and continued until recovery of lymphocyte count to grade 1 or less. The major efficacy outcome measure was overall survival. A total of 573 patients were randomized, 287 to temozolomide and radiation therapy and 286 to radiation therapy alone. At the time of disease progression, temozolomide was administered as salvage therapy in 161 patients of the 282 (57%) in the radiation therapy alone arm and 62 patients of the 277 (22%) in the temozolomide and radiation therapy arm. The addition of concomitant and maintenance temozolomide to radiation therapy for the treatment of patients with newly diagnosed glioblastoma showed a statistically significant improvement in overall survival compared to radiotherapy alone ( Figure 1 ). The hazard ratio (HR) for overall survival was 0.63 (95% CI: 0.52, 0.75) with a log-rank P <0.0001 in favor of the temozolomide arm. The median survival was increased by 2.5 months in the temozolomide arm. Figure 1 Kaplan-Meier Curves for Overall Survival (ITT Population) in Newly Diagnosed Glioblastoma Trial 14.2 Refractory Anaplastic Astrocytoma The efficacy of temozolomide was evaluated in Study MK-7365-006, a single-arm, multicenter trial. Eligible patients had anaplastic astrocytoma at first relapse and a baseline Karnofsky performance status (KPS) of 70 or greater. Patients had previously received radiation therapy and may also have previously received a nitrosourea with or without other chemotherapy. Fifty-four patients had disease progression on prior therapy with both a nitrosourea and procarbazine and their malignancy was considered refractory to chemotherapy (refractory anaplastic astrocytoma population). Temozolomide capsules were given on Days 1 to 5 of each 28-day cycle at a starting dose of 150 mg/m 2 /day. If ANC was ≥1.5 x 10 9 /L and platelet count was ≥100 x 10 9 /L at the nadir and on Day 1 of the next cycle, the temozolomide dose was increased to 200 mg/m 2 /day. The major efficacy outcome measure was progression-free survival at 6 months and the additional efficacy outcome measures were overall survival and overall response rate. In the refractory anaplastic astrocytoma population (n=54), the median age was 42 years (range: 19 to 76); 65% were male; and 72% had a KPS of >80. Sixty-three percent of patients had surgery other than a biopsy at the time of initial diagnosis. Of those patients undergoing resection, 73% underwent a subtotal resection and 27% underwent a gross total resection. Eighteen percent of patients had surgery at the time of first relapse. The median time from initial diagnosis to first relapse was 13.8 months (range: 4.2 months to 6.3 years). In the refractory anaplastic astrocytoma population, the overall response rate (CR+PR) was 22% (12 of 54 patients) and the complete response rate was 9% (5 of 54 patients). The median duration of all responses was 50 weeks (range: 16 to 114 weeks) and the median duration of complete responses was 64 weeks (range: 52 to 114 weeks). In this population, progression-free survival at 6 months was 45% (95% CI: 31%, 58%) and progression-free survival at 12 months was 29% (95% CI: 16%, 42%). Median progression-free survival was 4.4 months. Overall survival at 6 months was 74% (95% CI: 62%, 86%) and 12-month overall survival was 65% (95% CI: 52%, 78%). Median overall survival was 15.9 months. Image

8.5 Geriatric Use In the Newly Diagnosed Glioblastoma trial, Study MK-7365-051, 15% of patients were 65 years and older. This study did not include sufficient numbers of patients aged 65 years and older to determine differences in effectiveness from younger patients. No overall differences in safety were observed between patients ≥65 years and younger patients. In the Refractory Anaplastic Astrocytoma trial, Study MK-7365-0006, 4% of patients were 70 years and older. This study did not include sufficient numbers of patients aged 70 years and older to determine differences in effectiveness from younger patients. Patients 70 years and older had a higher incidence of Grade 4 neutropenia (25%) and Grade 4 thrombocytopenia (20%) in the first cycle of therapy than patients less than 70 years of age [see Warnings and Precautions ( 5.1 ), Adverse Reactions ( 6.1 )] .

8.4 Pediatric Use Safety and effectiveness of temozolomide have not been established in pediatric patients. Safety and effectiveness of temozlomide capsules were assessed, but not established, in 2 open-label studies in pediatric patients aged 3 to18 years. In one study, 29 patients with recurrent brain stem glioma and 34 patients with recurrent high-grade astrocytoma were enrolled. In a second study conducted by the Children's Oncology Group (COG), 122 patients were enrolled, including patients with medulloblastoma/PNET (29), high grade astrocytoma (23), low grade astrocytoma (22), brain stem glioma (16), ependymoma (14), other CNS tumors (9), and non-CNS tumors (9). The adverse reaction profile in pediatric patients was similar to adults.

8.1 Pregnancy Risk Summary Based on its mechanism of action [see Clinical Pharmacology ( 12.1 )] and findings from animal studies, temozolomide can cause fetal harm when administered to a pregnant woman. Available postmarketing reports describe cases of spontaneous abortions and congenital malformations, including polymalformations with central nervous system, facial, cardiac, skeletal, and genitourinary system anomalies with exposure to temozolomide during pregnancy. These cases report similar adverse developmental outcomes to those observed in animal studies. Administration of temozolomide to rats and rabbits during the period of organogenesis caused numerous external, internal, and skeletal malformations at doses less than the maximum human dose based on body surface area (see Data) . Advise pregnant women of the potential risk to a fetus. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data Five consecutive days of oral administration of temozolomide at doses of 75 mg/m 2 and 150 mg/m 2 (0.38 and 0.75 times the human dose of 200 mg/m 2 ) in rats and rabbits, respectively, during the period of organogenesis (Gestation Days 8 to 12) caused numerous malformations of the external and internal organs and skeleton in both species. In rabbits, temozolomide at the 150 mg/m 2 dose (0.75 times the human dose of 200 mg/m 2 ) caused embryolethality as indicated by increased resorptions.

Because of the potential for serious adverse reactions, including myelosuppression from temozolomide in the breastfed children, advise women not to breastfeed during treatment with temozlomide and for at least 1 week after the final dose. 8.3 Females and Males of Reproductive Potential Pregnancy Testing Verify pregnancy status in females of reproductive potential prior to initiating temozolomide [see Use in Specific Populations ( 8.1 )] . Contraception Females Temozolomide can cause embryo-fetal harm when administered to a pregnant woman [see Use in Specific Populations ( 8.1 )] . Advise females of reproductive potential to use effective contraception during treatment with temozolomide and for at least 6 months after the last dose. Males Because of the potential for embryofetal toxicity and genotoxic effects on sperm cells, advise male patients with pregnant partners or female partners of reproductive potential to use condoms during treatment with temozolomide and for at least 3 months after the final dose [see Use in Specific Populations ( 8.1 ), Nonclinical Toxicology ( 13.1 )] . Advise male patients not to donate semen during treatment with temozolomide and for at least 3 months after the final dose. Infertility Temozolomide may impair male fertility [see Nonclinical Toxicology ( 13.1 ) ] . Limited data from male patients show changes in sperm parameters during treatment with temozolomide; however, no information is available on the duration or reversibility of these changes. 8.4 Pediatric Use Safety and effectiveness of temozolomide have not been established in pediatric patients. Safety and effectiveness of temozlomide capsules were assessed, but not established, in 2 open-label studies in pediatric patients aged 3 to18 years.
