). 5 x 109 / L and platelets ≥100 x 109 / L. 0 x 109 / L or the platelet count is <50 x 109 / L during any cycle, the next cycle should be reduced one dose level. Dose levels include 100 mg / m2, 150 mg / m2, and 200 mg / m2. The lowest recommended dose is 100 mg / m2.
Dose modification for ACH-TEMOZOLOMIDE should be based on toxicities according to nadir ANC or platelet counts. Since women taking temozolomide capsules were reported to have a higher incidence of grade 4 neutropenia and thrombocytopenia than men in the first cycle of therapy, they must be closely monitored for abnormal neutrophil and platelet counts.
2 Recommended Dose and Dosage Adjustment Adults Patients with Newly Diagnosed Glioblastoma Multiforme: Concomitant Phase ACH-TEMOZOLOMIDE is administered at a dose of 75 mg / m2 daily for 42 days concomitant with radiotherapy (60 Gy administered in 30 fractions) followed by maintenance ACH-TEMOZOLOMIDE for 6 cycles.
No dose reductions are recommended; however, dose interruptions may occur based on patient tolerance. 5 x 109 / L; platelet count ≥100 x109 / L; common toxicity criteria (CTC) non-hematological toxicity Grade ≤1 (except for alopecia, nausea and vomiting).
During treatment a complete blood count should be obtained weekly. ACH-TEMOZOLOMIDE dosing should be interrupted or discontinued during concomitant phase according to the hematological and non-hematological toxicity criteria as noted in Table 1.

ACH-TEMOZOLOMIDE (temozolomide) Page 6 of 53 Maintenance Phase Four weeks after completing the ACH-TEMOZOLOMIDE + RT (Radiotherapy) phase, ACH- TEMOZOLOMIDE is administered for an additional 6 cycles of maintenance treatment.
Dosage in Cycle 1 (maintenance) is 150 mg / m2 once daily for 5 days followed by 23 days without treatment. 5 x 109 / L, and the platelet count is ≥ 100 x 109 / L. If the dose was not escalated at Cycle 2, escalation should not be done in subsequent cycles.
The dose remains at 200 mg / m2 per day for the first 5 days of each subsequent cycle except if toxicity occurs. Dose reductions during the maintenance phase should be applied according to Tables 2 and 3. During treatment a complete blood count should be obtained on day 22 (21 days after the first dose of ACH-TEMOZOLOMIDE).
and 4 DOSAGE AND ADMINISTRATION/Administration). Patients treated with temozolomide who experience myelosuppression, may experience prolonged pancytopenia, which may result in aplastic anemia, which in some cases has resulted in a fatal outcome.
In some cases, exposure to concomitant medications associated with aplastic anemia, including carbamazepine, phenytoin, and sulfamethoxazole / trimethoprim, complicates assessment. Hepatic/Biliary/Pancreatic Hepatotoxicity, including liver enzyme elevation, hyperbilirubinemia, cholestasis and hepatitis, has been observed with temozolomide use in the post-market setting (see 8 ADVERSE REACTIONS/Post-Market Adverse Drug Reactions).
Hepatic injury, including fatal hepatic failure, has been reported in patients treated with temozolomide. Baseline liver function tests should be performed prior to treatment initiation. If abnormal, physicians should assess the benefit/risk prior to initiating temozolomide including the potential for fatal hepatic failure.
For patients on a 42 day treatment cycle liver function tests should be repeated midway during this cycle. For all patients, liver function tests should be checked after each treatment cycle. For patients with significant liver function abnormalities, physicians should assess the benefit/risk of continuing treatment.
Liver toxicity may occur several weeks or more after the last treatment with temozolomide. In the absence of formal studies in patients suffering from severe hepatic dysfunction the treating physician should use his discretion in weighing the benefits of using ACH-TEMOZOLOMIDE in this patient population against the potential risks.
Additionally, hepatitis due to hepatitis B virus (HBV) reactivation, in some cases resulting in death, has been reported. Patients should be screened for HBV infection before treatment initiation. Patients with evidence of current or prior HBV infection should be monitored for clinical and laboratory signs of hepatitis or HBV reactivation during and for several months following treatment with ACH- TEMOZOLOMIDE.
2 Geriatrics Geriatrics (≥70 years old): Evidence from clinical studies and experience suggests that use in the geriatric population is associated with differences in safety or effectiveness. (see 7 WARNINGS AND PRECAUTIONS) 2 CONTRAINDICATIONS • ACH-TEMOZOLOMIDE is contraindicated in patients who have a history of hypersensitivity reaction to its components or to dacarbazine (DTIC).
• The use of ACH-TEMOZOLOMIDE is not recommended in patients with severe myelosuppression. 3 SERIOUS WARNINGS AND PRECAUTIONS BOX Serious Warnings and Precautions ACH-TEMOZOLOMIDE should be prescribed by a qualified healthcare professional who is experienced in the use of antineoplastic therapy.
The following are clinically significant adverse events: • Myelosuppression including Neutropenia and Thrombocytopenia and prolonged pancytopenia, which may result in aplastic anemia, which in some cases has resulted in a fatal outcome (see 7 WARNINGS AND PRECAUTIONS/Hematologic/ Myelosuppression).
• Hepatic injury, including fatal hepatic failure, has been reported in patients treated with temozolomide (see 7 WARNINGS AND PRECAUTIONS/ Hepatic/Biliary/Pancreatic). ACH-TEMOZOLOMIDE may have to be discontinued or the dose may have to be adjusted (see 4 DOSAGE AND ADMINISTRATION).

Malignant Gliomas Showing Recurrence or Progression after Standard Therapy:
Adult patients: In patients previously untreated with chemotherapy, ACH-TEMOZOLOMIDE is administered at a dose of 200 mg / m2 once daily for 5 days per 28-day cycle. For patients previously ACH-TEMOZOLOMIDE (temozolomide) Page 7 of 53 treated with chemotherapy, the initial dose is 150 mg / m2 once daily for 5 days, to be increased in the second cycle to 200 mg / m2 once daily for 5 days, providing there is no hematologic toxicity (see 7 WARNINGS AND PRECAUTIONS).
In the reference controlled trial of GBM, the majority of patients treated with temozolomide (90%) received more than one cycle and 22% of patients received 6 or more cycles. These patients received a total of 484 cycles of temozolomide capsules in total; 60% of cycles at 200 mg / m2 / day and 36% at 150 mg / m2 / day.
In the single arm AA trial, 93% of patients received more than one cycle and 25% of patients continued on study for 12 months or greater. Eighty-eight percent of patients were receiving either their initial dose or a higher dose at the last cycle.
However, limited experience is available on the prolonged use of temozolomide in this patient population. ACH-TEMOZOLOMIDE therapy can be continued until disease progression. 4 Administration ACH-TEMOZOLOMIDE Capsules ACH-TEMOZOLOMIDE should be […]
Therapy should be discontinued for patients with evidence of active hepatitis B infection. ACH-TEMOZOLOMIDE (temozolomide) Page 10 of 53 Infection Cases of herpes simplex encephalitis (HSE), including cases with fatal outcomes, were reported mostly in association with concomitant radiotherapy.
All patients, particularly those with previous herpes simplex infection need to be monitored for signs and symptoms of HSE during the treatment. Monitoring and Laboratory Tests Baseline liver function tests should be performed prior to treatment initiation.
If abnormal, physicians should assess the benefit / risk prior to initiating temozolomide including the potential for fatal hepatic failure. For patients on a 42 day treatment cycle liver function tests should be repeated midway during this cycle.
For all patients, liver function tests should be checked after each treatment cycle. Liver toxicity may occur several weeks or more after the last treatment with temozolomide. Patients should also be screened for HBV infection before treatment initiation.
Patients with evidence of current or prior HBV infection should be monitored for clinical and laboratory signs of hepatitis or HBV reactivation during and for several months following treatment with ACH-TEMOZOLOMIDE. Therapy should be discontinued for patients with evidence of active hepatitis B infection.
