Dosing Recommendations

Temozolomide for injection is available as Temodar 100-mg vials.

Refer to protocol by which member is being treated.  Numerous dosing schedules exist and depend on disease, response and concomitant therapy.  Guidelines for dosing also include consideration of absolute neutrophil count (ANC).  Dosage may be reduced, delayed or discontinued in member with bone marrow depression due to cytotoxic/radiation therapy or with other toxicities.

Newly Diagnosed GBM: 75 mg/m2 for 42 days concomitant with focal radiotherapy followed by initial maintenance dose of 150 mg/m2 once daily for Days 1-5 of a 28-day cycle of temozolomide for 6 cycles.

Refractory Anaplastic Astrocytoma: Initial dose 150 mg/m2 once daily for 5 consecutive days per 28-day treatment cycle.

The recommended dose for temozolomide as an intravenous infusion over 90 minutes is the same as the dose for the oral capsule formulation. Bioequivalence has been established only when temozolomide for injection was given over 90 minutes.

Temodar (temozolomide) is an alkylating antineoplastic agent. Temodar (temozolomide) undergoes rapid chemical conversion at physiologic pH to the active compound, monomethyl triazeno imidazole carboxamide (MTIC). The cytotoxicity of MTIC is thought to be due primarily to methylation of DNA at the O6 and N7 positions of guanine. Both temozolomide and dacarbazine are prodrugs of MTIC. The formation of Omethylguanine inhibits DNA replication through errant repair of the methyladduct and causes cell death via stimulation of p53 and apoptosis. Temodar (temozolomide) is cell-cycle non‐specific; however, cell cycle arrest usually occurs between the G2‐ and M-phases. The combination of Temodar (temozolomide) and radiation therapy results in additive effects.

Temodar (temozolomide) was approved by the U.S. Food and Drug Administration (FDA) for the treatment of adult patients with newly diagnosed glioblastoma multiforme concomitantly with radiotherapy and then as maintenance treatment. The labeling states that temozolomide is indicated for the treatment of adult patients with refractory anaplastic astrocytoma (i.e., patients who have experienced disease progression on a drug regimen containing nitrosourea and procarbazine).

Nausea and vomiting are known side effects of treatment and  should be medically treated, when they occur.  Current dosing recommendations by the manufacturer are not to withhold doses due to the adverse effects of vomiting.  Grade 3 or 4 vomiting occurred less than 1% in the clinical trials. 

Temozolomide is contraindicated in member with a history of hypersensitivity to dacarbazine.

Patient treated with Temodar (temozolomide) may experience myelosuppression, including 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. Prior to dosing, patient must have an absolute neutrophil count (ANC) ≥1.5 × 109/L and a platelet count ≥100 × 109/L. A complete blood count should be obtained on Day 22 (21 days after the first dose) or within 48 hours of that day, and weekly until the ANC is above 1.5 × 109/L and platelet count exceeds 100 × 109/L. Geriatric patient and women have been shown in clinical trials to have a higher risk of developing myelosuppression.

For treatment of newly diagnosed glioblastoma multiforme: Prophylaxis against Pneumocystis carinii pneumonia is required for all patient receiving concomitant Temodar (temozolomide) and radiotherapy for the 42‐day regimen. There may be a higher occurrence of PCP when Temodar (temozolomide) is administered during a longer dosing regimen. However, all patients receiving Temodar (temozolomide), particularly patient receiving steroids, should be observed closely for the development of PCP regardless of the regimen.

Temodar (temozolomide) should be given with caution to patient with severe hepatic disease, renal impairment (creatinine clearance < 36 ml/min), or renal failure. The pharmacokinetics of Temodar (temozolomide) has not been studied adequately in these patient populations.

Vaccination during Temodar (temozolomide) therapy should be avoided because the antibody response is suboptimal. When chemotherapy is being planned, vaccination should precede the initiation of chemotherapy by >= 2 weeks. The administration of live vaccines to immunocompromised patient should be avoided.

Extended Maintenance Temozolomide for Newly Diagnosed Glioblastoma

Gramatzki and colleagues (2017) examined an association with survival of modifying the current standard of care for patients with newly diagnosed glioblastoma of surgery followed by radiotherapy plus concurrent and 6 cycles of maintenance temozolomide chemotherapy (TMZ/RT → TMZ) by extending TMZ beyond 6 cycles.  The German Glioma Network cohort was screened for patients with newly diagnosed glioblastoma who received TMZ/RT → TMZ and completed greater than or equal to 6 cycles of maintenance chemotherapy without progression.  Associations of clinical patient characteristics, molecular markers, and residual tumor determined by magnetic resonance imaging (MRI) after 6 cycles of TMZ with progression-free survival (PFS) and overall survival (OS) were analyzed with the log-rank test.  Multi-variate analyses using the Cox proportional hazards model were performed to assess associations of prolonged TMZ use with outcome; 61 of 142 identified patients received at least 7 maintenance TMZ cycles (median of 11, range of 7 to 20).  Patients with extended maintenance TMZ treatment had better PFS (20.5 months, 95 % confidence interval [CI]: 17.7 to 23.3, versus 17.2 months, 95 % CI: 10.2 to 24.2, p = 0.035) but not OS (32.6 months, 95 % CI: 28.9 to 36.4, versus 33.2 months, 95 % CI: 25.3 to 41.0, p = 0.126).  However, there was no significant association of prolonged TMZ chemotherapy with PFS (hazard ratio [HR] = 0.8, 95 % CI: 0.4 to 1.6, p = 0.559) or OS (HR = 1.6, 95 % CI: 0.8 to 3.3, p = 0.218) adjusted for age, extent of resection, KPS, presence of residual tumor, O6-methylguanine DNA methyltransferase (MGMT) promoter methylation status, or isocitrate dehydrogenase (IDH) mutation status.  The authors concluded that these findings may not support the practice of prolonging maintenance TMZ chemotherapy beyond 6 cycles.  This study provided Class III evidence that in patients with newly diagnosed glioblastoma, prolonged TMZ chemotherapy did not significantly increase PFS or OS.

Chronic Lymphocytic Leukemia

Rao and co-workers (2017) reported a case of incidentally diagnosed chronic lymphocytic leukemia (CLL) in a patient with glioblastoma, which responded completely following standard treatment of the glioblastoma with TMZ and cranial irradiation.  The patient remained without an evidence of CLL until his death from recurrent glioblastoma.  The authors stated that further study of TMZ for the treatment of CLL is indicated.

Diffuse Large B-Cell Lymphoma

Cencini and associates (2017) noted that central nervous system (CNS) relapse is an infrequent; but severe complication for patients with diffuse large B-cell lymphoma (DLBCL) associated with poor prognosis.  Intravenous prophylaxis with high-dose methotrexate has shown promising results but is rarely feasible in elderly and/or nephropathic patients.  A 83-year old woman with CNS relapse occurred 6 months after chemoimmunotherapy.  The patient was defined ineligible for radiotherapy (RT) and started oral TMZ 250-mg daily for 5 consecutive days without any improvement after 1st cycle.  These researchers administered lenalidomide 25-mg daily for 21 days every 28 days together with TMZ 250-mg daily for 5 days every 28 days.  The patient experienced a rapid improvement of general and cognitive conditions; gadolinium-enhanced brain MRI showed a wide reduction of neoplastic tissue.  Patients maintained good clinical conditions with mild treatment toxicity until the end of the 6th cycle, when brain MRI showed disease progression and the patient died 1 month later.  The authors suggested lenalidomide could be a feasible option for CNS relapse in elderly DLBCL patients and it could be associated in future studies with other cytotoxic agents such as TMZ.

Metastatic Colorectal Cancer

Pishvaian and colleagues (2018) noted that poly(adenosine diphosphate ribose) polymerase (PARP) inhibitors such as veliparib are potent sensitizing agents and have been safely combined with DNA-damaging agents such as TMZ.  The sensitizing effects of PARP inhibitors are magnified when cells harbor DNA repair defects.  In a single-arm, open-label, phase-II clinical trial, these investigators examined the disease control rate (DCR) after 2 cycles of veliparib plus TMZ in patients with metastatic colorectal cancer (mCRC) refractory to all standard therapies.  A total of 50 patients received TMZ (150 mg/m2/day) on days 1 to 5 and veliparib (40 mg twice-daily) on days 1 to 7 of each 28-day cycle.  Another 5 patients with mismatch repair-deficient (dMMR) tumors were also enrolled; 20 additional patients were then treated with TMZ at 200 mg/m2/day.  Archived tumor specimens were used for immunohistochemistry (IHC) to assess mismatch repair, phosphatase and tensin homolog deleted on chromosome 10 (PTEN), and O(6)-methylguanine-DNA methyltransferase (MGMT) protein expression levels.  The combination was well-tolerated, although some patients needed dose reductions for myelosuppression.  The primary end-point was successfully met with a DCR of 24 % and 2 confirmed partial responses (PRs).  The median PFS was 1.8 months, and the median OS was 6.6 months; PTEN protein expression and MGMT protein expression were not predictors of DCR.  There was also a suggestion of worse outcomes for patients with dMMR tumors.  The authors concluded that in this heavily pre-treated mCRC population, a combination of veliparib and TMZ was well-tolerated with TMZ doses up to 200 mg/m2/day, and it was clinically active.  They stated that PARP inhibitor-based therapy merits further exploration in patients with mCRC.

Myxopapillary Ependymomas

Fujiwara and colleagues (2018) noted that myxopapillary ependymomas are intra-dural tumors that grow from the terminal filum of the spinal cord.  Although they are classified as WHO grade I, they sometimes cause cerebrospinal fluid (CSF) dissemination or local recurrence.  In this report, these investigators described a case in which TMZ showed remarkable efficacy on a recurrent spinal myxopapillary ependymoma.  A 26-year old woman underwent resection of an intra-dural myxopapillary ependymoma at L5 initially.  Although an en bloc total resection, including the capsule, could be achieved, she needed 2 additional tumor resection surgeries with post-operative radiotherapy at L4 and at L3 (2 and 6 years after the initial surgery, respectively).  Moreover, 4 years after the initial surgery, a disseminated metastatic tumor occurred at T11/12 and local radiotherapy was not effective.  After the 3rd surgery, an aggressive adjuvant therapy was necessary because there was a high risk of another recurrence.  Therefore, TMZ was administered for 1 year.  After 6 months of TMZ treatment, remarkably, the disseminated metastatic tumor at T11/12 had disappeared completely.  Presently, 6 years after finishing the TMZ treatment, the follow-up MRI has shown no recurrence in the brain and whole spine.  The authors concluded that TMZ is usually used in the treatment of glioblastoma and, recently, it has been reported to be effective for the lower grade spinal gliomas including spinal intramedullary ependymomas.  However, for myxopapillary ependymomas, there has been no report that TMZ is effective.  According to these findings, TMZ could be one of the possible candidates for adjuvant therapy in multiple recurrent myxopapillary ependymomas.  These preliminary findings need to be further investigated.


Dubois and associates (2018) stated that in phase-I testing, alisertib tablets with irinotecan and TMZ showed significant anti-tumor activity in patients with neuroblastoma.  This study sought to confirm activity of this regimen; evaluate an alisertib oral solution (OS); and evaluate biomarkers of clinical outcomes.  These researchers conducted a 2-stage, phase-II clinical trial of alisertib tablets (60 mg/m2/dose x 7 days), irinotecan (50 mg/m2/dose IV x 5 days), and TMZ (100 mg/m2/dose orally x 5 days) in patients with relapsed or refractory neuroblastoma.  The primary end-point was best objective response.  A separate cohort was treated with alisertib at 45 mg/m2 using OS instead of tablets.  Exploratory analyses sought to identify predictors of toxicity, response, and PFS using pooled data from phase-I, phase-II, and OS cohorts.  A total of 20 and 12 eligible patients were treated in the phase-II and OS cohorts, respectively.  Hematologic toxicities were the most common adverse events (AEs).  In phase-II, 4 PRs were observed in 19 evaluable patients (21 %).  The estimated PFS at 1 year was 34 %.  In the OS cohort, 3 patients (25 %) had 1st cycle dose-limiting toxicity (DLT).  Alisertib OS at 45 mg/m2 had significantly higher median Cmax and exposure compared to tablets at 60 mg/m2.  Higher alisertib trough concentration was associated with 1st cycle DLT, while MYCN amplification was associated with inferior PFS.  The authors concluded that this combination showed anti-tumor activity, particularly in patients with MYCN non-amplified tumors; data on an alisertib oral solution expanded the population able to be treated with this agent.

Pituitary Tumors

Barkhoudarian and colleagues (2018) noted that invasive, medically-refractory, and multiply-recurrent pituitary adenomas pose a rare but nevertheless significant challenge to conventional management modalities; TMZ has been reported to be useful as an adjunctive treatment in some patients.  These investigators described the efficacy of TMZ when used early in the management of invasive prolactinoma.  In this case-report, a 56-year old man presented with an invasive, refractory macroprolactinoma; and had failed long-term dopamine agonists, stereotactic radiosurgery and multiple trans-sphenoidal surgical resections, with persistent hyperprolactinemia and tumor progression.  He was consequently started on TMZ, and during the 11 cycles of TMZ therapy, the patient's prolactin level decreased from 696 ng/ml to 15.2 ng/ml with a greater than 90 % decrease in tumor size.  Nearly 6 years after discontinuing chemotherapy, the patient remained in sustained remission (prolactin level 3.1 ng/ml) requiring only 1.5 mg of cabergoline weekly, without radiographic or clinical evidence of tumor recurrence.  The authors concluded that TMZ could be effective in the management of medically and surgically refractory, invasive atypical prolactinomas resulting in normalization of prolactin levels and control of tumor size.  These researchers encouraged the inclusion of TMZ in the management of refractory, recurrent, and invasive prolactinomas, as a 4rth-line treatment strategy, after dopamine agonist treatment, trans-sphenoidal resection, and radiation therapy; they particularly advocated the early use of TMZ in aggressive and otherwise refractory prolactinomas.  This was a single-case study; its findings need to be further investigated.

Syro and associates (2018) reviewed the mechanism of action of TMZ as alkylating agent, its interaction with deoxyribonucleic acid repair systems, therapeutic effects in pituitary tumors, unresolved issues, and future directions relating to new possibilities of targeted therapy.  These investigators stated that overcoming and treating TMZ resistance has been a difficult clinical challenge.  Although medical management of TMZ resistance is limited at this time, great strides to understand its underlying mechanisms are being taken.  They stated that it is evident that arduous challenges persist and that it is crucial that research focus on the development of novel drugs that either enhance the effectiveness of TMZ or overcome its resistance.

Furthermore, an UpToDate review on “Management of hyperprolactinemia” (Synder, 2018) does not mention temozolomide as a therapeutic option.

Gilis-Januszewska and co-workers (2018) noted that aggressive pituitary tumors causing Cushing's disease are very rare, difficult to treat, and usually resistant to conventional therapy.  There is growing evidence for the use of TZM as 1st-line chemotherapy in tumors resistant to repeated neurosurgery, radiotherapy and adrenalectomy.  These researchers presented the response to TMZ in a rare case of an aggressive pituitary tumor in the course of Cushing's disease and reviewed the literature referring to similar cases.  In this report, these investigators presented the case of a 61-year old man who was diagnosed with Cushing's disease in the course of a pituitary invasive macro-adenoma in 2011.  The patient underwent 4 transphenoidal non-radical neurosurgeries (2012, 2013) with rapid tumor progression, repeated non-radical bilateral adrenalectomy (2012, 2013) and stereotactic radiotherapy, and gamma knife surgery (2013, 2015).  Histopathological examination revealed macro-adenoma with high cell polymorphism and the presence of Crooke's cells, Ki- less than 2 %.  Since 2015 the patient has been treated with 6 cycles of TMZ (320 mg per day for 5 consecutive days, 28-day cycle) with clinical and biochemical improvement and stabilized tumor size and no side effects; TMZ was continued for up to 9 cycles with a stable serum level of cortisol and ACTH being observed.  However, clinical symptoms like headaches, visual field impairment, and finally hearing loss started to progress from the 8th cycle.  After the 9th cycle of TMZ, there was a sudden increase in the size of the tumor, impairment of the cortisol and ACTH level, marked deterioration of the clinical status with the recurrence of severe headaches, narrowing of the visual field and hearing loss.  At the beginning of 2016, a sudden clinical status and sight deterioration, strong headaches, drop of the right eyelid with widening of the pupil were observed.  The patient died in February 2016.  The authors concluded that the findings of this case suggested that the response to the TMZ treatment monotherapy in aggressive pituitary tumor causing Cushing's disease could be partial and restricted to 7 to 8 cycles followed by rapid progression of the tumor mass; thus further research should be performed regarding new methods to extend the responsiveness and duration of TMZ treatment and to examine predictors of responsiveness.

Almalki and colleagues (2017) stated that pituitary tumors represent 10 to 15 % of all intra-cranial tumors; of these, prolactinomas account for 40 to 50 % of cases.  Prolactinomas usually respond well to dopamine agonists (DA) as 1st-line therapy.  However, treatment resistance remains a concern.  Temozolomide is an oral alkylating agent that has shown promise in treating aggressive pituitary adenomas and carcinomas that are resistant to other therapies.  To-date, no control trials have been undertaken and only single-case reports of pituitary tumors treated with TMZ have been published.  These investigators performed a systematic literature search for studies reporting the use of TMZ for the treatment of prolactinomas that were resistant to standard therapy.  A total of 42 reported cases were identified and included in this analysis: 23 cases of prolactin-secreting adenomas and 19 of prolactin-secreting carcinomas.  Prior to TMZ administration, patients had exhibited tumor progression and had previously undergone various treatments including surgery, radiotherapy, and drug therapy.  Tumor shrinkage was reported in 76 % of patients.  Reduced prolactin levels were observed in 75 % of patients, while normalization of prolactin was reported in 8 %; TMZ failure occurred in 20.6 % of cases.  Most patients exhibited no serious adverse effects.  The authors concluded that TMZ has potential for the treatment of highly aggressive and resistant prolactin-secreting adenomas and carcinomas, as demonstrated by tumor shrinkage or complete response (CR) and normalization of hormone hyper-secretion, and exhibited good tolerability and few side effects.

Aydogan and associates (2018) noted that treatment of aggressive pituitary tumors may be challenging; TMZ is a promising agent when conventional treatment methods fail.  These researchers presented the findings of 3 patients with aggressive pituitary tumors with atypical morphology, who were resistant to conventional treatments and treated with TMZ; 1st case had a somatotroph adenoma, 2nd case had a corticotroph adenoma, and the 3rd a macro-prolactinoma.  These investigators also reviewed the literature reporting TMZ efficacy in corticotroph, mammotroph and somatotroph tumors of the pituitary; TMZ, 150 to 200 mg/m2 for 5 days in a 28-day schedule was given to all patients.  Among the 3 patients studied in this report, even though only the case of macro-prolactinoma had a favorable response to TMZ treatment, both radiological and hormonal recurrences occurred 30 months after cessation of TMZ treatment.  Then TMZ treatment was applied again.  Cases of corticotroph and somatotroph had progressed under TMZ treatment and patients were lost due to mass effect of the tumor.  Review of the literature demonstrated 67.3 %, 60 % and 26.7 % overall response rates (ORRs) to the TMZ treatment in prolactinoma, corticotropinoma and somatostatinoma cases, respectively.  The authors concluded that there is still a need to define response criteria uniformly to TMZ treatment in aggressive pituitary tumors and the duration of response should be reported for reliable evaluation of results.
