A Phase I/Ib Study of MEK162, a MEK Inhibitor, in Combination With Carboplatin and Pemetrexed in Patients With Non-squamous Carcinoma of the Lung — MEK162  

Lungcancer Clinical Trial

Official title: A Phase I/Ib Study of MEK162, a MEK Inhibitor, in Combination With Carboplatin and Pemetrexed in Patients With Non-squamous Carcinoma of the Lung

Status Completed

Clinical Trial Summary

MEK162 has shown significant inhibition of tumor growth as a single agent in NSCLC xenograft models in mice and human cancer cells in vitro, which have KRAS and/or other mutations. These data suggest that MEK162 may provide a potential benefit in cancer indications harboring these mutations. MEK162 is currently being investigated in phase I clinical testing and has been well tolerated up to an MTD of 45mg BID in cancer patients.

There has been little change in survival benefit for patients with non-small cell lung cancer in recent years. Emerging new treatment options relying on molecular and genetic markers are being studied extensively. Thus, there has been a shift to manage non-small cell lung cancer with molecular targeted therapies in combination with standard chemotherapy. This study will be targeting patients with KRAS mutations.

Clinical Trial Description

OBJECTIVES

1.1 Primary Objectives

• To assess the safety of MEK162 administered in combination with carboplatin and pemetrexed as first line treatment in advanced non-small cell lung cancer (NSCLC).

• To determine the recommended phase II dose (RP2D) of MEK162 to be used when given in a continuous dosing schedule together with pemetrexed and carboplatin administered on a 3-weekly schedule as first line treatment in advanced NSCLC.

• To explore the efficacy (as measured by tumor response in the Phase Ib portion) of the combination of MEK162 in addition to pemetrexed and carboplatin in treatment-naïve patients with EGFR wild-type, ALK-rearrangement negative NSCLC of the lung.

1.2 Secondary Objectives

• To characterize the population pharmacokinetics of MEK162 administered in combination with carboplatin and pemetrexed (Phase I).

• To explore relationships between KRAS mutation (and sub-types) and additional genomic mutations and objective clinical response.

1.3 Trial End-points Primary Phase I • Development of dose-limiting toxicity (DLT), (defined in section 4.3) as measured with NCI CTC AE v4.

Phase Ib

• Objective response rate (ORR) as per RECIST v1.1.

Secondary Phase I • Adverse events, serious adverse events, changes in hematology and chemistry values, vital signs, ECGs.

Phase Ib

• Evaluation of response rate (RR), progression-free survival (PFS) and disease control rate (DCR) for patients with and without KRAS mutation in tumor tissue.

• Exploratory analysis of KRAS mutation sub-type.

Exploratory end-points

• A limited sampling strategy pharmacokinetic model will be used to ensure that the clearance of MEK162 is not influenced by the concurrent administration of pemetrexed-based chemotherapy. ;
