Trial of MEK Inhibitor and PI3K/mTOR Inhibitor in Subjects With Locally Advanced or Metastatic Solid Tumors

MSC1936369B (pimasertib) single dose capsule was administered at dose of 15 milligram (mg), 30 mg, 60 mg, 90 mg orally in successive 21-day cycles.Dose escalation was proceeded until Maximum Tolerated Dose (MTD) was reached. Once the MTD was reached, enrollment began in four disease-specific expansion cohorts at either the MTD or a lower dose recommended by the Safety Monitoring Committee. The four expansion cohorts enrolled subjects with Breast Cancer, Non-Small Cell Lung Cancer (NSCLC), Melanoma, and Colorectal Cancer.

SAR245409 (PI3K and mTOR inhibitor) capsule was administered orally at a dose of 30 mg, 50 mg, 70 mg and 90 mg in successive 21-day cycles. Dose escalation was proceeded until MTD was reached. Once the MTD was reached, enrollment began in four disease-specific expansion cohorts at either the MTD or a lower dose recommended by the Safety Monitoring Committee. The four expansion cohort enrolled subjects with Breast Cancer, NSCLC, Melanoma, and Colorectal Cancer.

MSC1936369B (pimasertib) capsule was administered twice daily orally at a dose of 60 mg and 45 mg in successive 21-day cycles. Dose escalation proceeded until MTD was reached. The maximum tolerated dose of MSC1936369B (pimasertib) was combined with a lower dose of SAR245409 (PI3K and mTOR inhibitor).
