|Study Design:||Endpoint Classification: Pharmacokinetics Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
|Official Title:||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)|
- Number of patients experiencing a dose-limiting toxicity (DLT) as a Measure of Safety and Tolerability [ Time Frame: 18 months ] [ Designated as safety issue: Yes ]Phase 1: The optimal dose of BKM120 to administer in combination with standard dose bevacizumab determined as the highest dose at which ≤1 of 6 patients experiences a DLT assessed using NCI CTCAE v4.0.
- Median Progression-Free Survival [ Time Frame: every 8 weeks, estimated 24 months ] [ Designated as safety issue: No ]Phase 2: Measured from the date of first protocol treatment until date of tumor progression or death occurs, or date of last adequate tumor assessment analyzed using Kaplan-Meier methods..
- Frequency and severity of adverse events as a measure of toxicity. [ Time Frame: every 8 weeks, projected 24 months ] [ Designated as safety issue: Yes ]Safety will be evaluated for patients in Phase I and II based on NCI CTCAE v4.0 criteria.
- Overall Survival (OS) [ Time Frame: every 8 weeks, projected 24 months ] [ Designated as safety issue: No ]Measured as the interval from first study treatment until date of death, or date last known alive.
- Overall Response Rate [ Time Frame: every 8 weeks, projected 24 months ] [ Designated as safety issue: No ]Proportion of patients with confirmed complete or partial responses (CR or PR) according to RECIST v1.1 criteria.

This is an open-label, non-randomized Phase I study of patients with advanced refractory solid tumors followed by a Phase II study for the second-line treatment of patients with relapsed/refractory glioblastoma multiforme.
In the phase I part of the study the MTD of BKM120 when combined with bevacizumab was determined to be 60 mg/day. In the Phase II part of this study, patients with relapsed/refractory GBM following first line therapy are being treated with the BKM120/bevacizumab combination. Limited BKM120 pharmacokinetic evaluation will be performed on all patients treated during this part of the study. Patients will be reevaluated for response to treatment after 2 cycles (8 weeks). Patients with objective response or stable disease will continue treatment, with subsequent reevaluations every 8 weeks, until disease progression or unacceptable toxicity occurs.
Two populations of patients with relapsed/refractory GBM will be treated in the Phase II trial: 1) patients with no previous exposure to bevacizumab (N= 55) and 2) patients who received bevacizumab as part of first-line combined modality treatment (N= 20).
