Preclinical data in lung cancer cell lines showed that EGFR mutation can potentially be a positive predictor for sensitivity to BKM120. Furthermore, when the erlotinib-resistant model H1975 (LR858 and T790M mutation) was treated with BKM120, significant tumor control was observed (Novartis internal data). Therefore, combining BKM120 with erlotinib could potentially down-modulate PI3K-Akt activity resulting in a synergistic effect on cell growth inhibition and enhancing the response to erlotinib.
Name: BKM120 and Erlotinib
Description: Percentage of patients who are alive and progression-free at 3 months (APF3) from first treatment.
Measure: Progression Free Survival at 3 Months Time: 3 monthsDescription: Defined as the time from first treatment until death from any cause.
Measure: Overall Survival Time: every 3 months after study treatment, projected 24 monthsDescription: Defined as the time from complete or partial response (CR or PR) until objective tumor progression. Tumor measurements will be obtained using CT scans of chest, abdomen and pelvis and assessed per RECIST v 1.1. Complete response (CR) is defined as a disappearance of all lesions; partial response (PR) is defined as at least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking the baseline sum LD as reference. Stable Disease (SD) is defined as neither sufficient shrinkage to qualify for PR, nor sufficient increase to qualify for progressive disease, taking as reference the smallest (nadir) sum LD since start of treatment.
Measure: Duration of Response Time: every 8 weeks for 12 months, then every 12 weeks thereafter, estimated 18 monthsDescription: Defined as the percentage of complete and partial responses (CR + PR) among all patients. Complete response (CR) is defined as a disappearance of all lesions; partial response (PR) is defined as at least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking the baseline sum LD as reference. Stable Disease (SD) is defined as neither sufficient shrinkage to qualify for PR, nor sufficient increase to qualify for progressive disease, taking as reference the smallest (nadir) sum LD since start of treatment.
Measure: Objective Response Rate Time: every 8 weeks for 12 months, then every 12 weeks thereafter, estimated 18 monthsDescription: Adverse events will be graded using CTCAE v4.3. and will be collected until 30 days after the discontinuation of study treatment for each participant. A non-serious adverse event is any untoward medical occurrence. A serious adverse event (SAE) is an event that meets one or more of the following: results in death; is life-threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; is a congenital anomaly/birth defect; requires intervention to prevent permanent impairment or damage. Specific AE and SAE terms are provided in the Adverse event module.
Measure: Number of Participants With Serious and Non-serious Adverse Events as a Measure of Safety. Time: Every 2 weeks for 8 weeks, then every 8 weeks thereafter, estimated 24 monthsAllocation: N/A
