Phase 1/2 CTO + Bevacizumab for Recurrent Glioma Post-Bevacizumab Failure
A Phase 1/2 Trial of Carboxyamidotriazole Orotate (CTO) Alone or in Combination With Bevacizumab for Adult Patients With Recurrent Malignant Glioma Post-Bevacizumab Failure
The primary objectives of the study are to determine the maximum tolerated dose (MTD) of Carboxyamidotriazole Orotate (CTO) when combined with standard dosing of bevacizumab among patients with recurrent malignant glioma (WHO grade III or IV) that have previously failed bevacizumab (Phase 1); to determine the activity of CTO alone in bevacizumab-failure WHO grade IV malignant glioma patients (Phase 2, Arm 1); to determine the activity of CTO plus bevacizumab in bevacizumab-failure WHO grade IV malignant glioma patients (Phase 2, Arm 2).
This study was terminated early due to funding issues. At the time of termination, the study was still in Phase 1 and no MTD for the combination of CTO and bevacizumab had been determined for this population. Phase 2 will not proceed.

Detaljerad beskrivning
In Phase 1 of the study, we will conduct a dose-escalation study of the combination of CTO with the standard dosing of bevacizumab among patients with recurrent malignant glioma (WHO Grade III or IV) that have previously failed bevacizumab. All patients will have also received standard treatment with radiation therapy and temozolomide prior to enrollment on study.
The Phase 2 portion of this study will investigate two novel treatment regimens sequentially. Each regimen will include 25 patients with recurrent WHO grade IV malignant glioma who have been treated in the past with standard radiation therapy, temozolomide, and bevacizumab. All patients must have failed therapy while on bevacizumab. Subjects in the first treatment regimen will receive CTO alone and subjects in the second treatment regimen will receive the combination of CTO and bevacizumab together.
Note: This study was terminated early due to funding issues. At the time of termination, the study was still in Phase 1 and no MTD for the combination of CTO and bevacizumab had been determined for this population. Phase 2 will not proceed.

Phase 1: Determine the Maximum Tolerated Dose (MTD) of CTO when combined with standard dosing of bevacizumab
Tidsram: 1 year
|
A standard "3+3" design to determine the MTD of CTO in combination with bevacizumab.
Subjects will be administered CTO orally on a continuous daily dosing schedule, while subjects will receive bevacizumab (10 mg/kg) every 2 weeks.
Cohorts of 3-6 subjects will accrue at each dose level of CTO, beginning with 225 mg/m2, until MTD is defined.
The MTD is the highest dose level at which ≤ 1 out of 6 experienced a dose limiting toxicity (DLT).
