Brief summary
The purpose of this signal seeking study was is to determine whether treatment with BKM120 demonstrates sufficient efficacy in select pathway-activated solid tumors and/or hematologic malignancies to warrant further study.
Interventions
BKM120 100 mg (oral gelatine capsules) was administered orally once daily starting from cycle 1 day 1 and will be dosed continuously every day for each 28-day cycle

| Participant Clinical Benefit Response Rate | Week 16 | Clinical benefit rate for patients with solid tumors will be assessed using RECIST 1.1 and will include responses of Complete Response (CR) or Partial Response (PR) or Stable Disease (SD) at \>=16 weeks. For hematologic tumors other appropriate hematological response criteria was applied. Response criteria: CR=Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm., PR=At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters, SD=Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study, PD= At least a 20% increase in the sum of diameter of all measured target lesions, taking as reference the smallest sum of diameter of all target lesions recorded at or after baseline |
