Combination of BKM120 and Bevacizumab in Refractory Solid Tumors and Relapsed/Refractory Glioblastoma Multiforme
In this phase I/II study, the investigators plan to evaluate 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.

|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)|
- To establish the optimal dose of BKM120 that can be administered in combination with a standard dose of bevacizumab. (Phase I) [ Time Frame: 18 months ] [ Designated as safety issue: No ]
- To evaluate the efficacy of the BKM120/bevacizumab combination in patients with relapsed/refractory GBM. [ Time Frame: 18 months ] [ Designated as safety issue: No ]For evaluation of efficacy, patients previously treated with bevacizumab will be considered separately from those with no previous bevacizumab treatment.
- To evaluate the toxicity of the BKM120/bevacizumab combination. [ Time Frame: 18 months ] [ Designated as safety issue: Yes ]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.
- To evaluate the pharmacokinetics of BKM120 when administered concurrently with bevacizumab [ Time Frame: 18 months ] [ Designated as safety issue: Yes ]
The purposes of PK sampling are:
- to detect any alteration in BKM120 PK caused by concurrent administration of bevacizumab
- to detect any alterations in patients receiving concurrent treatment with mild CYP3A4 inhibitors or inducers.

Combination of BKM120 and Bevacizumab
Bevacizumab 10 mg/kg IV every 2 weeks
Other Name: AvastinDrug: BKM120
BKM120 PO once daily
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.
The phase I study will determine the MTD of BKM120 when combined with bevacizumab. The Phase I portion will follow a standard dose escalation design, beginning with dose level 1. The sequence of dose escalation for BKM120 and bevacizumab is based on a starting dose of 60 mg/day for BKM120 (i.e. 50% of the MTD of BKM120 when administered as a single agent). A maximum of three BKM120 dose levels will be evaluated. Bevacizumab will be fixed at 10 mg/kg IV and will be administered every two weeks. Approximately 18 patients will be enrolled during the Phase I portion to establish the MTD.
In the Phase II portion of this study, patients with relapsed/refractory GBM following first line therapy will receive treatment with the BKM120/bevacizumab combination. Limited BKM120 pharmacokinetic evaluation will be performed on all patients treated during the Phase II portion 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).
