Newly Diagnosed Anaplastic Astrocytoma The safety of temozolomide for the adjuvant treatment of adults with newly diagnosed anaplastic astrocytoma was derived from published literature [see Clinical Studies (14.2)]. The safety of temozolomide for the adjuvant treatment of patients with newly diagnosed anaplastic astrocytoma was consistent with the known safety profile of temozolomide. Refractory Anaplastic Astrocytoma The safety of temozolomide was evaluated in study MK-7365-006 [see Clinical Studies (14.2)]. The most common adverse reactions (≥20%) were nausea, vomiting, headache, fatigue, constipation, and convulsions.

In the entire safety database for which hematologic data exist (N=932), 7% (4/61) and 10% (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 6% (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 postapproval 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 serious 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-(3-methyltriazen-1-yl)-imidazole-4-carboxamide. Reactions to temozolomide have included anaphylaxis [see Adverse Reactions (6.2)]. History of serious hypersensitivity to temozolomide or any other ingredients in temozolomide capsules and dacarbazine. (4)

11 DESCRIPTION Temozolomide is an alkylating drug. The chemical name of temozolomide is 3,4-dihydro-3-methyl-4-oxoimidazo[5,1-d]- as -tetrazine-8-carboxamide. The structural formula of temozolomide is: The material is a white to light tan or light pink powder with a molecular formula of C 6 H 6 N 6 O 2 and a molecular weight of 194.15. The molecule is stable at acidic pH (<5) and labile at pH >7; hence temozolomide capsules, USP can be administered orally. The prodrug, temozolomide, is rapidly hydrolyzed to the active 5-(3-methyltriazen-1-yl) imidazole-4-carboxamide (MTIC) at neutral and alkaline pH values, with hydrolysis taking place even faster at alkaline pH. Each capsule for oral use contains either 5 mg, 20 mg, 100 mg, 140 mg, 180 mg, or 250 mg of temozolomide, USP. The inactive ingredients for temozolomide capsules, USP are: lactose anhydrous, sodium starch glycolate, tartaric acid, and stearic acid. The capsule shell contains gelatin, titanium dioxide, and sodium lauryl sulfate. The imprinting ink contains shellac, dehydrated alcohol, butyl alcohol, propylene glycol, strong ammonia solution, FD&C Blue # 1 Aluminum Lake (5 mg, 140 mg), yellow iron oxide (5 mg, 20 mg, 100 mg), red iron oxide (100 mg, 180 mg), titanium dioxide (100 mg, 140 mg), potassium hydroxide (100 mg, 250 mg) and black iron oxide (250 mg). spl-temozolomide-structure

(2.4) Newly Diagnosed Glioblastoma: o 75 mg/m2 once daily for 42 to 49 days concomitant with focal radiotherapy followed by initial maintenance dose of 150 mg/m2 once daily for Days 1 to 5 of each 28-day cycle for 6 cycles. May increase maintenance dose to 200 mg/m2 for Cycles 2 to 6 based on toxicity. (2.1) o Provide Pneumocystis pneumonia (PCP) prophylaxis during concomitant phase and continue in patients who develop lymphopenia until resolution to Grade 1 or less. (2.1) Adjuvant Treatment of Newly Diagnosed Anaplastic Astrocytoma: Beginning 4 weeks after the end of radiotherapy, administer temozolomide orally in a single dose on days 1 to 5 of a 28-day cycle for 12 cycles. The recommended dosage for Cycle 1 is 150 mg/m2 per day and for Cycles 2 to 12 is 200 mg/m2 if patient experienced no or minimal toxicity in Cycle 1. (2.2) Refractory Anaplastic Astrocytoma: Initial dose of 150 mg/m2 once daily on Days 1 to 5 of each 28-day cycle. (2.2) 2.1 Monitoring to Inform Dosage and Administration Prior to dosing, withhold temozolomide capsules until patients have an absolute neutrophil count (ANC) of 1.5 x 109/L or greater and a platelet count of 100 x 109/L or greater. For concomitant radiotherapy, obtain a complete blood count prior to initiation of treatment and weekly during treatment. For the 28-day treatment cycles, obtain a complete blood count prior to treatment on Day 1 and on Day 22 of each cycle. Perform complete blood counts weekly until recovery if the ANC falls below 1.5 x 109/L and the platelet count falls below 100 x 109/L. For concomitant use with focal radiotherapy, obtain a complete blood count weekly and as clinically indicated. 2.2 Recommended Dosage and Dosage Modifications for Newly Diagnosed Glioblastoma Administer temozolomide capsules once daily for 42 to 49 consecutive days during the concomitant use phase with focal radiotherapy, and then once daily on Days 1 to 5 of each 28-day cycle for 6 cycles during the maintenance use phase. Provide Pneumocystis pneumonia (PCP) prophylaxis during the concomitant use phase and continue in patients who develop lymphopenia until resolution to Grade 1 or less [see Warnings and Precautions (5.3)]. Concomitant Use Phase: The recommended dosage of temozolomide capsules is 75 mg/m2 once daily for 42 to 49 days in combination with focal radiotherapy. Focal radiotherapy includes the tumor bed or resection site with a 2 to 3 cm margin. Other administration schedules have been used. Obtain a complete blood count weekly. The recommended dosage modifications due to adverse reactions during concomitant use phase are provided in Table 1. TABLE 1: Dosage Modifications Due to Adverse Reactions During Concomitant Use Phase Adverse Reaction Interruption Discontinuation Absolute Neutrophil Count Withhold temozolomide capsules if ANC is greater than or equal to 0.5 x 10 9 /L and less than 1.5 x 10 9 /L.

Resume temozolomide capsules at the same dose when resolution to Grade 1 or less. Discontinue temozolomide capsules if Grade 3 or 4 adverse reaction occurs. Single Agent Maintenance Use Phase: Beginning 4 weeks after concomitant use phase completion, administer temozolomide capsules once daily on Days 1 to 5 of each 28-day cycle for 6 cycles. The recommended dosage of temozolomide capsules in the maintenance use phase is: • Cycle 1: 150 mg/m2 per day on days 1 to 5. • Cycles 2 to 6: May increase to 200 mg/m2 per day on days 1 to 5 before starting Cycle 2 if no dosage interruptions or discontinuations are required (Table 1). If the dose is not escalated at the onset of Cycle 2, do not increase the dose for Cycles 3 to 6. Obtain a complete blood count on Day 22 and then weekly until the ANC is above 1.5 x 109/L and the platelet count is above 100 x 109/L. Do not start the next cycle until the ANC and platelet count exceed these levels. The recommended dosage modifications due to adverse reactions during the maintenance use phase are provided in Table 2. If temozolomide capsules are withheld, reduce the dose for the next cycle by 50 mg/m2 per day. Permanently discontinue temozolomide capsules in patients who are unable to tolerate a dose of 100 mg/m2 per day. TABLE 2: Dosage Modifications Due to Adverse Reactions During Maintenance and Adjuvant Treatment Adverse Reactions Interruption and Dose Reduction Discontinuation Absolute Neutrophil Count Withhold temozolomide capsules if ANC less than 1 x 10 9 /L. When ANC is above 1.5 x 10 9 /L, resume temozolomide capsules at reduced dose for the next cycle. Discontinue temozolomide capsules if unable to tolerate a dose of 100 mg/m2 per day. Platelet Count Withhold temozolomide capsules if platelet less than 50 x 10 9 /L. When platelet count is above 100 x 10 9 /L, resume temozolomide capsules at reduced dose for the next cycle. Discontinue temozolomide capsules if unable to tolerate a dose of 100 mg/m2 per day. Non-hematological Adverse Reactions (except for alopecia, nausea, vomiting) Withhold temozolomide capsules if Grade 3 adverse reaction occurs. When resolved to Grade 1 or less, resume temozolomide capsules at reduced dose for the next cycle. Discontinue temozolomide capsules if recurrent Grade 3 adverse reaction occurs after dose reduction, if Grade 4 adverse reaction occurs, or if unable to tolerate a dose of 100 mg/m2 per day. 2.3 Recommended Dosage and Dosage Modifications for Anaplastic Astrocytoma Adjuvant Treatment of Newly Diagnosed Anaplastic Astrocytoma Beginning 4 weeks after the end of radiotherapy, administer temozolomide capsules orally in a single dose on days 1 to 5 of a 28-day cycle for 12 cycles. The recommended dosage of temozolomide capsules is: • Cycle 1: 150 mg/m2 per day on days 1 to 5. • Cycles 2 to 12: 200 mg/m2 per day on days 1 to 5 if patient experienced no or minimal toxicity in Cycle 1. If the dose was not escalated at the onset of Cycle 2, do not increase the dose during Cycles 3 to 6. The recommended complete blood count testing and dosage modifications due to adverse reactions during adjuvant treatment are provided above and in Table 2 [see Dosage and Administration (2.2)]. Refractory Anaplastic Astrocytoma The recommended initial dosage of temozolomide capsules are 150 mg/m2 once daily on Days 1 to 5 of each 28-day cycle. Increase the temozolomide dose to 200 mg/m2 per day if the following conditions are met at the nadir and on Day 1 of the next cycle: • ANC is greater than or equal to 1.5 x 109/L, and • Platelet count is greater than or equal to 100 x 109/L. Continue temozolomide capsules until disease progression or unacceptable toxicity. Obtain a complete blood count on Day 22 and then weekly until the ANC is above 1.5 x 109/L and the platelet count is above 100 x 109/L. Do not start the next cycle until the ANC and platelet count exceed these levels. If the ANC is less than 1 x 109/L or the platelet count is less than 50 x 109/L during any cycle, reduce the temozolomide dose for the next cycle by 50 mg/m2 per day. Permanently discontinue temozolomide capsules in patients who are unable to tolerate a dose of 100 mg/m2 per day. 2.4 Preparation and Administration Temozolomide is a hazardous drug. Follow applicable special handling and disposal procedures. 1 Temozolomide capsules Take temozolomide capsules at the same time each day. Administer temozolomide capsules consistently with respect to food (fasting vs. nonfasting) [see Clinical Pharmacology (12.3)]. To reduce nausea and vomiting, take temozolomide capsules on an empty stomach or at bedtime and consider antiemetic therapy prior to and following temozolomide capsule administration. Swallow temozolomide capsules whole with water. Advise patients not to open, chew, or dissolve the contents of the capsules [see Warnings and Precautions (5.6)]. 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, wash the affected area with water immediately.

1 INDICATIONS AND USAGE Temozolomide is an alkylating drug indicated for the treatment of adults with: • Newly diagnosed glioblastoma concomitantly with radiotherapy and then as maintenance treatment. (1.1) • Anaplastic astrocytoma. (1.2) o Adjuvant treatment of adults with newly diagnosed anaplastic astrocytoma. (1.2) o Treatment of adults with refractory anaplastic astrocytoma. (1.2) 1.1 Newly Diagnosed Glioblastoma Temozolomide capsules are indicated for the treatment of adults with newly diagnosed glioblastoma, concomitantly with radiotherapy and then as maintenance treatment. 1.2 Anaplastic Astrocytoma Temozolomide capsules are indicated for the: • adjuvant treatment of adults with newly diagnosed anaplastic astrocytoma; • treatment of adults with refractory anaplastic astrocytoma.

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-(3-methyltriazen-1-yl)-imidazole-4-carboxamide (MTIC). The cytotoxicity of MTIC is thought to be primarily due to DNA alkylation, mainly at the O6 and N7 positions of guanine, which causes DNA double strand breaks and results in programmed cell death. 12.2 Pharmacodynamics Temozolomide exposure-response relationships and the time course of pharmacodynamic response are unknown. 12.3 Pharmacokinetics Following a single oral dose of 150 mg/m 2 , the mean C max is 7.5 mcg/mL for temozolomide and 282 ng/mL for MTIC. The mean AUC is 23.4 mcg·hr/mL for temozolomide and 864 ng·hr/mL for MTIC. Following a single 90-minute intravenous infusion of 150 mg/m 2 , the mean C max is 7.3 mcg/mL for temozolomide and 276 ng/mL for MTIC. The mean AUC is 24.6 mcg·hr/mL for temozolomide and 891 ng·hr/mL for MTIC. 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 temozolomide C max and AUC decreased by 32% and 9%, respectively, and median T max increased by 2-fold (from 1 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 (CV%) apparent volume of distribution of 0.4 L/kg (13%). The mean percent bound of drug-related total radioactivity is 15%. Elimination Clearance of temozolomide is approximately 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 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 Approximately 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 recovered radioactivity in urine is unchanged temozolomide (6%), AIC (12%), temozolomide acid metabolite (2.3%), and unidentified polar metabolite(s) (17%). Specific Populations No clinically significant differences in the pharmacokinetics of temozolomide were observed based on age (range: 19 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 Clinical Studies and Model-Informed Approaches No clinically significant differences in the pharmacokinetics of temozolomide or MTIC were observed when coadministered with ranitidine. No clinically significant differences in the clearance of temozolomide or MTIC were predicted when coadministered with the following drugs: valproic acid, dexamethasone, prochlorperazine, phenytoin, carbamazepine, ondansetron, histamine-2-receptor antagonists, or phenobarbital.

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 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 and 125 mg/m 2 (0.25 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 .

PHARMACIST INFORMATION SHEET IMPORTANT DISPENSING INFORMATION For every patient, dispense Temozolomide in its original package, making sure each container lists the strength per capsule and that patients take the appropriate number of capsules from each package. Please see the dispensing instructions below for more information. What is temozolomide ? [See Full Prescribing Information, Indications and Usage (1).] Temozolomide is an oral alkylating agent for the treatment of newly diagnosed glioblastoma multiforme and refractory anaplastic astrocytoma. How is temozolomide dosed? [See Full Prescribing Information, Recommended Dosage and Dosage Modifications for Newly Diagnosed Glioblastoma (2.1), Recommended Dosage and Dosage Modifications for Refractory Anaplastic Astrocytoma (2.2).] The physician calculates the daily dose of temozolomide capsules for a given patient based on the patient’s body surface area (BSA). Round off the resulting dose to the nearest 5 mg. An example of the dosing may be as follows: the initial daily dose of temozolomide in milligrams is the BSA multiplied by mg/m 2 /day (e.g., a patient with a BSA of 1.84 is 1.84 x 75 mg = 138, or 140 mg/day). Adjust the dose for subsequent cycles according to nadir neutrophil and platelet counts in the previous cycle and at the time of initiating the next cycle. How might the dose of temozolomide be modified for Refractory Anaplastic Astrocytoma? [See Full Prescribing Information, Recommended Dosage and Dosage Modifications for Refractory Anaplastic Astrocytoma (2.2).] The initial dose is 150 mg/m 2 orally once daily for 5 consecutive days per 28-day treatment cycle. Increase the temozolomide capsules dose to 200 mg/m 2 /day for 5 consecutive days per 28-day treatment cycle if both the nadir and day of dosing (Day 29, Day 1 of next cycle) absolute neutrophil counts (ANC) are greater than or equal to 1.5 × 10 9 /L (1,500/µL) and both the nadir and Day 29, Day 1 of next cycle platelet counts are greater than or equal to 100 × 10 9 /L (100,000/µL). During treatment, obtain a complete blood count on Day 22 (21 days after the first dose), and weekly until the ANC is above 1.5 × 10 9 /L (1,500/µL) and the platelet count exceeds 100 × 10 9 /L (100,000/µL). Do not start the next cycle of temozolomide until the ANC and platelet count exceed these levels. If the ANC falls to less than 1 × 10 9 /L (1,000/µL) or the platelet count is less than 50 × 10 9 /L (50,000/µL) during any cycle, reduce the dose for the next cycle by 50 mg/m 2 . Permanently discontinue temozolomide capsules in patients who are unable to tolerate a dose of 100 mg/m 2 per day. Patients should continue taking temozolomide until their physician determines that their disease has progressed or until unacceptable side effects or toxicities occur. In the clinical trial, treatment could be continued for a maximum of 2 years, but the optimum duration of therapy is not known. Physicians may alter the treatment regimen for a given patient. Dosing for Patients with Newly Diagnosed Glioblastoma Multiforme [See Full Prescribing Information, Recommended Dosage and Dosage Modifications for Newly Diagnosed Glioblastoma (2.1).] Concomitant Phase Treatment Schedule Administer temozolomide orally at 75 mg/m 2 daily for 42 days concomitant with focal radiotherapy (60 Gy administered in 30 fractions), followed by maintenance temozolomide for 6 cycles. No dose reductions are recommended; however, dose interruptions may occur based on patient tolerance. Continue the temozolomide dose throughout the 42-day concomitant period up to 49 days if all of the following conditions are met: absolute neutrophil count greater than or equal to 1.5 × 10 9 /L, platelet count greater than or equal to 100 ×10 9 /L, and nonhematological adverse reactions less than or equal to Grade 1 (except for alopecia, nausea and vomiting). During treatment, obtain a complete blood count weekly. Interrupt or discontinue temozolomide dosing during the concomitant phase according to the hematological and nonhematological toxicity criteria [see Table 1 in the Full Prescribing Information, Recommended Dosage and Dosage Modifications for Newly Diagnosed Glioblastoma (2.1)] . Pneumocystis pneumonia (PCP) prophylaxis is required during the concomitant administration of temozolomide and radiotherapy, and should be continued in patients who develop lymphocytopenia until resolution to Grade 1 or less. Maintenance Phase Treatment Schedule Four weeks after completing the temozolomide and radiotherapy phase, administer temozolomide for an additional 6 cycles of maintenance treatment. Dosage in Cycle 1 (maintenance) is 150 mg/m 2 once daily for 5 days followed by 23 days without treatment. At the start of Cycle 2, escalate the dose to 200 mg/m 2 , if the nonhematologic adverse reactions for Cycle 1 are Grade less than or equal to 2 (except for alopecia, nausea and vomiting), absolute neutrophil count (ANC) is greater than or equal to 1.5 × 10 9 /L, and the platelet count is greater than or equal to 100 × 10 9 /L. If the dose was not escalated at Cycle 2, do not escalate the dose in subsequent cycles. Maintain the dose at 200 mg/m 2 per day for the first 5 days of each subsequent cycle except if toxicity occurs. During treatment, obtain a complete blood count on Day 22 (21 days after the first dose) and weekly until the ANC is above 1.5 × 10 9 /L (1,500/µL) and the platelet count exceeds 100 × 10 9 /L (100,000/µL). Do not start the next cycle of temozolomide until the ANC and platelet count exceed these levels. Base dose reductions during the next cycle on the lowest blood counts and worst nonhematologic adverse reactions during the previous cycle. Apply dose reductions or discontinuations during the maintenance phase [see Table 2 in the Full Prescribing Information, Recommended Dosage and Dosage Modifications for Newly Diagnosed Glioblastoma (2.1)] . How is temozolomide taken? [See Full Prescribing Information, Preparation and Administration, temozolomide capsules (2.3).] Advise patients to take each day’s dose with a full glass of water, preferably on an empty stomach or at bedtime. Taking the medication on an empty stomach or at bedtime may help ease nausea. If patients are also taking anti-nausea or other medications to relieve the side effects associated with temozolomide, advise them to take these medications prior to and/or following administration of temozolomide capsules. Advise patients that temozolomide capsules should be swallowed whole and NEVER CHEWED . Advise patients that they SHOULD NOT open or split the capsules. If capsules are accidentally opened or damaged, advise patients to take rigorous precautions with the capsule contents to avoid inhalation or contact with the skin or mucous membranes. In case of powder contact, advise the patients to wash their hands. Advise patients to keep this medication away from children. What should the patient avoid during treatment with temozolomide capsules? [See Full Prescribing Information, Use in Specific Populations, Pregnancy (8.1), Lactation (8.2), Females and Males of Reproductive Potential (8.3).] There are no dietary restrictions for patients taking temozolomide capsules. Temozolomide capsules may affect testicular function and may cause birth defects. Advise male patients to exercise adequate birth control measures. Advise female patients to avoid becoming pregnant while receiving this drug. Advise pregnant women of the potential risk to the fetus. Advise females of reproductive potential to use effective contraception during treatment and for at least 6 months after the last dose. Advise males of reproductive potential to use condoms during treatment and for at least 3 months after the last dose. Advise male patients not to donate semen during treatment with temozolomide and for at least 3 months after the final dose. It is not known whether temozolomide is excreted into breast milk. Because of the potential for serious adverse reactions in breastfed children, advise women not to breastfeed while taking temozolomide capsules and for at least 1 week after the last dose. What are the side effects of temozolomide capsules? [See Full Prescribing Information, Adverse Reactions (6).] Alopecia, fatigue, nausea, and vomiting are the most common side effects associated with temozolomide capsules. Noncumulative myelosuppression is the dose-limiting toxicity. Patients should be evaluated periodically by their physician to monitor blood counts. Other commonly reported side effects reported by patients taking temozolomide capsules are headache, constipation, anorexia, and convulsions. How is temozolomide capsules supplied? [See Full Prescribing Information, How Supplied/Storage and Handling (16).] Temozolomide is available as capsules in 5 mg, 20 mg, 100 mg, 140 mg, 180 mg, and 250 mg strengths. Temozolomide capsules contain a white capsule body with a white cap. Imprinting ink colors vary based on the dosage strength. Temozolomide Capsules Strength Imprinting Ink Color 5 mg Green 20 mg Yellow 100 mg Pink 140 mg Blue 180 mg Reddish brown 250 mg Black The 5 mg, 20 mg, 100 mg, 140 mg, 180 mg, and 250 mg capsule strengths are available in 5 count, 14 count and 20 count bottle packs and 5 count and 20 count blister packs. The 5 mg, 20 mg, 100 mg, 140 mg, and 180 mg capsule strengths are also available in 15 count blister packs. How is temozolomide dispensed? Dispense each strength of temozolomide in its original package (one strength per one container). Follow the instructions below: Based on the dose prescribed, determine the number of each strength of temozolomide capsules needed for the full 42 or 5 day cycle as prescribed by the physician. For example, in a 5 day cycle, 275 mg/day would be dispensed as five 250 mg capsules, five 20 mg capsules and five 5 mg capsules. Label each container with the appropriate number of capsules to be taken each day. Dispense to the patient, making sure each container lists the strength (mg) per capsule and that he or she understands to take the appropriate number of capsules of temozolomide from each package to equal the total daily dose prescribed by the physician. How can temozolomide be ordered? Temozolomide can be ordered from your wholesaler. It is important to understand if temozolomide is being used as part of a 42 day regimen or as part of a 5 day course. Remember to order enough temozolomide for the appropriate cycle. For example: a 5 day course of 360 mg/day would require the following to be ordered: two 5 count packages of 180 mg capsules. a 42 day course of 140 mg/day would require the following to be ordered: three 14 count packages of 140 mg capsules.

14 CLINICAL STUDIES 14.1 Newly Diagnosed Glioblastoma The efficacy of temozolomide was evaluated in MK-7365-051 ( NCT00006353 ), 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 overall survival was 14.6 months in the temozolomide arm and 12.1 months for radiation therapy alone arm. FIGURE 1: Kaplan-Meier Curves for Overall Survival (ITT Population) in Patients with Newly Diagnosed Glioblastoma in MK-7365-051 spl-temozolomide-figure-1 14.2 Anaplastic Astrocytoma Newly Diagnosed Anaplastic Astrocytoma The efficacy of temozolomide for the adjuvant treatment of newly diagnosed anaplastic astrocytoma was derived from studies of temozolomide in the published literature. Temozolomide was evaluated in CATNON (NCT00626990), a randomized, open-label, multicenter trial, where the major efficacy outcome measure was overall survival. 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/m2/day. If ANC was ≥1.5 x 109/L and platelet count was ≥100 x 109/L at the nadir and on Day 1 of the next cycle, the temozolomide dose was increased to 200 mg/m2/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.

8.5 Geriatric Use In MK-7365-051, 15% of patients with newly diagnosed glioblastoma 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. The CATNON trial did not include sufficient numbers of patients aged 65 years and older to determine differences in safety or effectiveness when compared to younger patients. In MK-7365-006, 4% of patients with refractory anaplastic astrocytoma 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)]. In the entire safety database for which hematologic data exist (N=932), 7% (4/61) and 10% (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 6% (48/879) experienced Grade 4 neutropenia or thrombocytopenia in the first cycle, respectively. Pancytopenia, leukopenia, and anemia also occurred.

8.4 Pediatric Use Safety and effectiveness of temozolomide have not been established in pediatric patients. Safety and effectiveness of temozolomide capsules were assessed, but not established, in 2 open-label studies in pediatric patients aged 3 to 18 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 findings from animal studies and its mechanism of action [see Clinical Pharmacology (12.1)], 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 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.

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. 8.2 Lactation There are no data on the presence of temozolomide or its metabolites in human milk, the effects on a breastfed child, or the effects on milk production. Because of the potential for serious adverse reactions, including myelosuppression from temozolomide in the breastfed children, advise women not to breastfeed during treatment with temozolomide and for 1 week after the last dose. 8.3 Females and Males of Reproductive Potential Temozolomide can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1)]. Pregnancy Testing Verify pregnancy status in females of reproductive potential prior to initiating temozolomide [see Use in Specific Populations (8.1)] . Contraception Females Advise females of reproductive potential to use effective contraception during treatment with temozolomide and for 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 3 months after the last 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 3 months after the last 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.

Pancytopenia, leukopenia, and anemia also occurred. 8.6 Renal Impairment No dosage adjustment is recommended for patients with creatinine clearance (CLcr) of 36 to 130 mL/min/m2 [see Clinical Pharmacology (12.3)]. The recommended dose of temozolomide has not been established for patients with severe renal impairment (CLcr <36 mL/min/m2) or for patients with end-stage renal disease on dialysis. 8.7 Hepatic Impairment No dosage adjustment is recommended for patients with mild to moderate hepatic impairment (Child Pugh class A and B) [see Clinical Pharmacology (12.3) ]. The recommended dose of temozolomide has not been established for patients with severe hepatic impairment (Child-Pugh class C).
