    2.3 Preparation and Administration

    Temozolomide is a cytotoxic drug. Follow applicable special handling and disposal procedures.1

    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/or following temozolomide capsules 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.

  • 4 CONTRAINDICATIONS

    Temozolomide capsules are 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-(3-methyltriazen-1-yl)-imidazole-4-carboxamide.

    Reactions to temozolomide capsules have included anaphylaxis [see Adverse Reactions (6.2)].

  • 5 WARNINGS AND PRECAUTIONS

    5.1 Myelosuppression

    Myelosuppression, including pancytopenia, leukopenia and anemia, some with fatal outcomes, have occurred with temozolomide capsules [see Adverse Reactions (6.1, 6.2)]. Geriatric patients and women have been shown in clinical trials to have a higher risk of developing myelosuppression.

    Prior to dosing, patients must have an ANC of 1.5 x 109/L or greater and a platelet count of 100 x 109/L or greater.

    For the concomitant phase with radiotherapy, obtain a complete blood count prior to initiation of treatment and weekly during treatment [see Dosage and Administration (2.1)].

    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 [see Dosage and Administration (2.1, 2.2)].

    5.2 Myelodysplastic Syndrome and Secondary Malignancies

    Cases of myelodysplastic syndrome and secondary malignancies, including myeloid leukemia, have been observed following temozolomide capsule administration.

    5.3 Pneumocystis Pneumonia

    Pneumocystis pneumonia (PCP) can occur in patients receiving temozolomide capsules. The risk of PCP is increased in patients receiving steroids or with longer treatment regimens.

    For patients with newly diagnosed glioblastoma, provide PCP prophylaxis for all patients during the concomitant phase. Continue in patients who experience lymphopenia until resolution to grade 1 or less [see Dosage and Administration (2.1)].

    Monitor all patients receiving temozolomide capsules for the development of lymphopenia and PCP.

    5.4 Hepatotoxicity

    Fatal and severe hepatotoxicity have been reported in patients receiving temozolomide. Perform liver tests at baseline, midway through the first cycle, prior to each subsequent cycle, and approximately two to four weeks after the last dose of temozolomide.

    5.5 Embryo-Fetal Toxicity

    Based on findings from animal studies and its mechanism of action, temozolomide capsules can cause fetal harm when administered to a pregnant woman. Adverse developmental outcomes have been reported in both pregnant patients and pregnant partners of male patients. Oral administration of temozolomide to rats and rabbits during the period of organogenesis resulted in embryolethality and polymalformations at doses less than the maximum human dose based on body surface area.

    Advise pregnant women of the potential risk to the fetus. Advise females of reproductive potential to use effective contraception during treatment with temozolomide capsules and for at least 6 months after the final dose. Because of potential risk of genotoxic effects on sperm, advise male patients with female partners of reproductive potential to use condoms during treatment with temozolomide capsules and for at least 3 months after the final dose. Advise male patients not to donate semen during treatment with temozolomide capsules and for at least 3 months after the final dose [see Use in Specific Populations (8.1, 8.3)].

  • 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)].

    6.1 Clinical Trials Experience

    Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

    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.

    Note: Grade 5 (fatal) adverse reactions are included in the Grade ≥3 column.

    When laboratory abnormalities and adverse reactions were combined, Grade 3 or Grade 4 neutrophil abnormalities including neutropenic reactions were observed in 8% of patients, and Grade 3 or Grade 4 platelet abnormalities including thrombocytopenic reactions, were observed in 14% of patients.

    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.

    Hematological Toxicities for Advanced Gliomas

    In clinical trial experience with 110 to 111 females and 169 to 174 males (depending on measurements), females experienced higher rates of Grade 4 neutropenia (ANC < 0.5 x 109/L) and thrombocytopenia (< 20 x 109/L) than males in the first cycle of therapy (12% vs. 5% and 9% vs. 3%, respectively).

    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

  • 8 USE IN SPECIFIC POPULATIONS

    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 capsules 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/m2 (0.38 and 0.75 times the human dose of 200 mg/m2) in rats and rabbits, respectively, during the period of organogenesis (Gestation Days 8-12) caused numerous malformations of the external and internal organs and skeleton in both species. In rabbits, temozolomide at the 150 mg/m2 dose (0.75 times the human dose of 200 mg/m2) 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 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 capsules [see Use in Specific Populations (8.1)].

    Contraception

    Females

    Temozolomide capsules 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 capsules 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 capsules 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 capsules and for at least 3 months after the final dose.

    Infertility

    Temozolomide capsules may impair male fertility [see Nonclinical Toxicology (13.1)]. Limited data from male patients show changes in sperm parameters during treatment with temozolomide capsules; however, no information is available on the duration or reversibility of these changes.

    8.4 Pediatric Use

    Safety and effectiveness of temozolomide capsules 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.

    8.5 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)].

    8.6 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).

  • 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.

  • 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:

    structure

    The material is a white to light tan/light pink powder with a molecular formula of C6H6N6O2 and a molecular weight of 194.15. The molecule is stable at acidic pH (<5) and labile at pH >7; hence temozolomide can be administered orally and intravenously. 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.

    Temozolomide Capsules USP, for oral use, contain either 5 mg, 20 mg, 100 mg, 140 mg, 180 mg, or 250 mg of temozolomide USP.

    The inactive ingredients are as follows: lactose anhydrous, colloidal silicon dioxide, sodium starch glycolate, tartaric acid, and stearic acid.

    The body of the capsules is made of gelatin and titanium dioxide, and are opaque white. The cap is also made of gelatin, and the colors vary based on the dosage strength. The capsule body and cap are imprinted with pharmaceutical branding ink, which contains shellac, dehydrated alcohol, isopropyl alcohol, butyl alcohol, propylene glycol, purified water, strong ammonia solution, potassium hydroxide, and black iron oxide.

    • Temozolomide Capsules USP 5 mg: The green cap contains gelatin, titanium dioxide, iron oxide yellow, and FD&C Blue #1.
    • Temozolomide Capsules USP 20 mg: The gold cap contains gelatin and iron oxide yellow.
    • Temozolomide Capsules USP 100 mg: The pink cap contains gelatin, titanium dioxide, FD&C Blue #1, D&C Red # 40 and FD&C Yellow #6
    • Temozolomide Capsules USP 140 mg: The blue cap contains gelatin, FD&C Blue #1. D&C Red # 28 and FD&C Red #40.
    • Temozolomide Capsules USP 180 mg: The dark orange cap contains gelatin, titanium dioxide, FD&C Blue #1, FD&C Red #40 and FD&C Yellow #6.
    • Temozolomide Capsules USP 250 mg: The white opaque cap contains gelatin and titanium dioxide.
  • 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 alkylation of DNA. Alkylation (methylation) occurs mainly at the O6 and N7 positions of guanine.

    12.3 Pharmacokinetics

    Following a single oral dose of 150 mg/m2, the mean Cmax 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.

    Temozolomide exhibits linear kinetics over the therapeutic dosing range of 75 mg/m2/day to 250 mg/m2/day.

    Absorption

    The median Tmax is 1 hour.

    Effect of Food

    The mean Cmax and AUC decreased by 32% and 9%, respectively, and median Tmax increased by 2-fold (from 1-2.25 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/m2 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: 19-78 years), gender, smoking status (smoker vs. non-smoker), creatinine clearance (CLcr) of 36 to 130 mL/min/m2, 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/m2, 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 Cmax 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 NONCLINICAL TOXICOLOGY

    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 (25-125 mg/m2) 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/m2 (0.25 and 0.63 times the human dose of 200 mg/m2) in rats and dogs, respectively, and testicular atrophy in dogs at 125 mg/m2.

    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/m2 (0.63 times the human dose of 200 mg/m2). These changes were most commonly seen at doses where mortality was observed.

  • 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/m2 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/m2 or 200 mg/m2 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

    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/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.

    • Use a condom for birth control (contraception) during treatment and for at least 3 months after taking your final dose of temozolomide capsules.
    • Do not donate semen during treatment and for at least 3 months after your final dose of temozolomide capsules.

    See the section “What are the possible side effects of Temozolomide Capsules?” for more information about side effects.

    What are Temozolomide Capsules?

    Temozolomide capsules are a prescription medicine used to treat adults with certain brain cancer tumors.

    It is not known if temozolomide capsules are safe and effective in children.

    Who should not take Temozolomide Capsules?

    Do not take temozolomide capsules if you:

    • have had an allergic reaction to temozolomide or any of the other ingredients in temozolomide capsules. See the end of this leaflet for a list of ingredients in temozolomide capsules. Symptoms of an allergic reaction with temozolomide capsules may include: a red itchy rash, or a severe allergic reaction, such as trouble breathing, swelling of the face, throat, or tongue, or severe skin reaction. If you are not sure, ask your doctor.
    • have had an allergic reaction to dacarbazine (DTIC), another cancer medicine.

    What should I tell my doctor before taking Temozolomide Capsules?

    Tell your doctor about all your medical conditions, including if you:

    • have kidney problems
    • have liver problems
    • are pregnant or plan to become pregnant. See “What is the most important information I should know about Temozolomide Capsules?”
    • are breast-feeding or plan to breastfeed. It is not known if temozolomide passes into breast milk. Do not breastfeed during treatment and for at least 1 week after your last dose of temozolomide capsules.

    Tell your doctor about all the medicines you take, including prescription and non-prescription medicines, vitamins, and herbal supplements. Especially tell your doctor if you take a medicine that contains valproic acid.

    Know the medicines you take. Keep a list of them and show it to your doctor and pharmacist when you get a new medicine.

    How should I take Temozolomide?

    Temozolomide may be taken two different ways:

    • you may take temozolomide by mouth as a capsule, or
    • you may receive temozolomide as an intravenous (IV) injection into a vein.

    Your doctor will decide the best way for you to take temozolomide. Take temozolomide exactly as prescribed by your doctor.

    There are two common dosing schedules for taking temozolomide depending on the type of brain cancer tumor that you have.

    • People with certain brain cancer tumors take or receive temozolomide:
      • o One time each day for 42 days in a row (possibly 49 days depending on side effects) along with receiving radiation treatment. This is one cycle of treatment.
      • o After this, your doctor may prescribe 6 more cycles of temozolomide as “maintenance” treatment. For each of these cycles, you take or receive temozolomide one time each day for 5 days in a row and then you stop taking it for the next 23 days. This is a 28-day maintenance treatment cycle.
    • People with certain other brain cancer tumors take or receive temozolomide:
      • o One time each day for 5 days in a row only, and then stop taking it for the next 23 days. This is one cycle of treatment (28 days).
      • o Your doctor will watch your progress on temozolomide and decide how long you should take it. You might take temozolomide until your tumor gets worse or for possibly up to 2 years.
    • If your doctor prescribes a treatment regimen that is different from the information in this leaflet, make sure you follow the instructions given to you by your doctor.
    • Your doctor may change your dose of temozolomide, or tell you to stop temozolomide for a short period of time or permanently if you have certain side effects.
    • Your doctor will decide how many treatment cycles of temozolomide that you will receive, depending on how you respond to and tolerate treatment.

    Temozolomide Capsules:

    • Take temozolomide capsules exactly as your doctor tells you to.
    • Temozolomide capsules contain a white capsule body with a color cap and the colors vary based on the dosage strength. Your doctor may prescribe more than one strength of temozolomide capsules for you, so it is important that you understand how to take your medicine the right way. Be sure that you understand exactly how many capsules you need to take on each day of your treatment, and what strengths to take. This may be different whenever you start a new cycle.
    • Do not take more temozolomide capsules than prescribed.
    • Talk to your doctor or pharmacist before taking your dose if you are not sure how much temozolomide to take. This will help to prevent taking too much temozolomide and decrease your chances of getting serious side effects.
    • Take each day’s dose of temozolomide capsules at one time, with a full glass of water.
    • Swallow temozolomide capsules whole. Do not chew, open, or split the capsules.
    • Take temozolomide capsules at the same time each day.
    • Take temozolomide capsules the same way each time, either with food or without food.
    • If temozolomide capsules are accidentally opened or damaged, be careful not to breathe in (inhale) the powder from the capsules or get the powder on your skin or mucous membranes (for example, in your nose or mouth). If contact with any of these areas happens, flush the area with water.
    • To help reduce nausea and vomiting, try to take temozolomide capsules on an empty stomach or at bedtime. Your doctor may prescribe medicine to help prevent or treat nausea, or other medicines to reduce side effects with temozolomide capsules.
    • See your doctor regularly to check your progress. Your doctor will check you for side effects.
    • If you take more temozolomide capsules than prescribed, call your doctor or get emergency medical help right away.

    What are the possible side effects of Temozolomide Capsules?

    Temozolomide capsules can cause serious side effects, including:

    • See “What is the most important information I should know about Temozolomide Capsules?”
    • Decreased blood cell counts. Temozolomide capsules can affect your bone marrow and cause you to have decreased blood cell counts. Decreased white blood cell count, red blood cell count and platelet count are common with temozolomide capsules but it can also be severe and lead to death.
      • o Your doctor will do blood tests regularly to check your blood cell counts before you start and during treatment with temozolomide capsules.
      • o Your doctor may need to change the dose of temozolomide capsules, or when you get it depending on your blood cell counts.
      • o People who are age 70 or older and women have a higher risk for developing decreased blood cell counts during treatment with temozolomide capsules.
    • Secondary cancers. Blood problems such as myelodysplastic syndrome (MDS) and new cancers (secondary cancers), including a certain kind of leukemia, can happen in people who take temozolomide capsules. Your doctor will monitor you for this.
    • Pneumocystis pneumonia (PCP). PCP is an infection that people can get when their immune system is weak. Temozolomide capsules decrease white blood cells, which makes your immune system weaker and can increase your risk of getting PCP.
      • o People who are taking steroid medicines or who stay on temozolomide capsules for a longer period of time may have an increased risk of getting PCP infection.
      • o Anyone who takes temozolomide capsules will be watched carefully by their doctor for low blood cell counts and this infection.
      • o Tell your doctor if you have any of the following signs and symptoms of PCP infection: shortness of breath, or fever, chills, dry cough.
    • Liver problems. Liver problems can happen with temozolomide capsules and can sometimes be severe and lead to death. Your doctor will do blood tests to check your liver function before you start taking temozolomide capsules, during treatment, and about 2 to 4 weeks after your last dose of temozolomide capsules.

    Common side effects of temozolomide capsules include:

    • hair loss
    • feeling tired
    • nausea and vomiting
    • headache
    • constipation
    • loss of appetite
    • convulsions
    • rash
    • diarrhea
    • unable to move (paralysis) on one side of the body
    • weakness
    • fever
    • dizziness
    • coordination problems
    • viral infection
    • memory loss
    • sleep problems

    Temozolomide Capsules can affect fertility in males and may affect your ability to father a child. Talk with your doctor if fertility is a concern for you.
