Phase I/II Study of the Combination of BKM120 and Bevacizumab in Patients With Refractory Solid Tumors (Phase I) and Relapsed/Refractory Glioblastoma Multiforme (Phase II)
In this phase I/II study,investigators are evaluating the feasibility and efficacy of the combination of BKM120, an oral inhibitor of PI3 kinase, and bevacizumab in the treatment of patients with relapsed/refractory GBM. In the Phase I part of the trial, the optimal BKM120 dose to be administered with a standard dose of bevacizumab will be determined in patients with refractory solid tumors. Although it is unlikely that the concurrent administration of bevacizumab will alter the pharmacokinetics of BKM120, limited pharmacokinetic sampling will be performed on all patients treated during the Phase II portion of the study. Assuming this combination is feasible, the Phase II portion of the study will proceed, using the doses determined in the Phase I portion. In the phase II portion, eligible patients will be limited to those with recurrent/progressive GBM following 1st line combined modality therapy.

Conditions
- Glioblastoma Multiforme
Interventions
- Bevacizumab
- BKM120
Primary outcomes
- Number of Phase I Patients Receiving 60mg or 80mg BKM120 Experiencing a Dose-Limiting Toxicity (DLT) to Determine the Optimal Dosage — Collected from day of first dose to the end of the first treatment cycle, up to 28 days
The optimal dose of BKM120 to administer in combination with standard dose bevacizumab determined as the dose at which ≤1 of 6 patients experiences a DLT assessed using NCI CTCAE v4.03 during Cycle 1 (28 days). The optimal dose of BKM120 was determined to be 60 mg by mouth (PO), once a day for each 28 day cycle along with bevacizumab, administered 10 mg/kg intravenously (IV) on Day 1 and Day 15 of each 28 day cycle. - Median Progression-Free Survival (PFS) in Phase II Participants - Prior Bevacizumab and Bevacizumab Naive — every 8 weeks for up to 33 months
Two groups of patients in the Phase II trial will be considered separately, 1) participants who have not received previous bevacizumab and 2) participants who have received bevacizumab as part of first-line treatment. PFS is measured from the date of first protocol treatment until date of disease progression or death occurs, or date of last adequate tumor assessment using RANO or McDonald criteria. McDonald disease progression criteria: a 25% or greater increase in sum of the diameters of lesions, new lesions, or clinical deterioration (McDonald et al, 1990). RANO disease progression criteria: a 25% or greater increase in the enhancing lesions sum compared with smallest tumor measurement, significant increase in T2/FLAIR nonenhancing lesion on stable or increasing corticosteroids, new lesions, or clinical deterioration (Wen et al 2010)
