Study of IDO Inhibitor and Temozolomide for Adult Patients With Primary Malignant Brain Tumors
Glioblastoma Multiforme, Glioma, Gliosarcoma
About this trial
This is an interventional treatment trial for Glioblastoma Multiforme focused on measuring glioblastoma multiforme, glioma, gliosarcoma, malignant brain tumor
Eligibility Criteria
Inclusion Criteria:
- Histologically proven intracranial glioblastoma multiforme (WHO grade IV glioma) or gliosarcoma. In addition, the Phase 1b cohort will include patients with progressive WHO grade III glioma.
- Patients will be eligible if the original histology was lower grade glioma and a subsequent diagnosis of glioblastoma or gliosarcoma is made.
- Unequivocal radiographic evidence for tumor progression by MRI. It is understood that some patients may be resected prior to enrolling onto protocol
- Patients must have completed a course of radiation therapy and at least 2 adjuvant cycles of temozolomide for the phase 2 component.
- Patients enrolling onto Cohort 2b who have been taken off bevacizumab must have had at least a 28 day washout from any previous administration of bevacizumab. It is preferred that patients who fail bevacizumab prior to trial entry remain on bevacizumab in the trial.
- Prior temozolomide is not required for the phase 1 component; prior radiation is required for the phase 1 arm.
- Patients must be on a steroid dose less than or equal to 2 mg of dexamethasone daily (or equivalent), and this dose must not have increased for at least 14 days prior to obtaining the enrollment.
- ECOG performance status ≤1 or Karnofsky ≥70%.
- Age between 16
- Must be 28 days from the administration of any investigational agent or prior cytotoxic therapy with the following exceptions:
- Must be 14 days from administration of non-cytotoxic agents (e.g., bevacizumab (except COHORT 2b), interferon, tamoxifen, thalidomide, cis-retinoic acid, tyrosine kinase inhibitor, etc.).
Exclusion Criteria:
- Prior invasive malignancy that is not low-grade glioma, high-grade glioma, glioblastoma, or gliosarcoma (except non-melanomatous skin cancer or carcinoma in situ of the cervix) unless the patient has been disease free and off therapy for that disease for a minimum of 3 years.
- Patients on the phase 2 portion of the study may not have more than 2 prior regimens for recurrent disease for glioblastoma/gliosarcoma. Patients on the phase 1 portion of the study may not have had more than 3 prior regimens.
- Systemic corticosteroid therapy > 2 mg of dexamethasone daily (or equivalent) at study enrollment.
- Active or history of autoimmune disease

Phase 1B patients will receive Indoximod given in escalating doses. Initial dosing will be 600 mg BID by mouth with escalation planned to 1200 mg BID by mouth. The medication should be taken twice daily for 28 days each cycle. Temozolomide will also be given by mouth at 150 mg/m^2 x 5 days at all dosing levels of indoximod. Each cycle is 28 days. Patients will continue until they experience disease progression or toxicity.
Bevacizumab naïve phase II patients who will receive indoximod with temozolomide. Indoximod will be dosed at 1200mg BID. Temozolomide will be dosed at 150 mg/m2 and may be escalated up to 200 mg/m2.
Phase II patients who will receive indoximod with temozolomide and bevacizumab who have previously been treated with bevacizumab. Indoximod will be dosed at 1200mg BID. Temozolomide will be dosed at 150 mg/m2 and may be escalated up to 200 mg/m2. Bevacizumab will be dosed at 10mg/kg.
Phase II patients who will receive indoximod with temozolomide and stereotactic radiosurgery. Indoximod will be dosed at 1200mg BID. Temozolomide will be dosed at 150 mg/m2 and may be escalated up to 200 mg/m2. Single fraction SRS dose will be 16 or 20 Gy depending on target volume. The total 5-fraction SRT dose will be 27.5 Gy.
