MSC2015103B in Solid Tumors

A Phase I Dose-Escalation First-In-Human Trial to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of the Oral MEK Inhibitor MSC2015103B Administered With Two Different Treatment Schedules in Subjects With Advanced Solid Tumors

The main purpose of this study is to test the experimental drug, MSC2015103B at different dose levels and on different treatment schedules, to see whether it is safe and can be tolerated when given to subjects once a day one day per week over a 21-day period or once a day three times per week over a 21-day period. The investigators would also like to find out how MSC2015103B is broken down by the body.

Additional purposes of the trial are to assess side effects of MSC2015103B and to find out whether MSC2015103B has anti-cancer effects. In addition, the investigators would like to explore pharmacokinetics.

CR: The disappearance of all target and non-target lesions and normalization of tumor marker level; PR: At least a 30% decrease in the sum of the longest diameter of target lesions, taking as reference the sum of the longest diameter at baseline.	Every 6 Weeks until complete response or till data cut-off date 15 July 2013
Percentage of Subjects With Clinical Benefit	Clinical benefit was to be confirmed by CR, PR or stable disease (SD) lasting at least 6 weeks (using RECIST v1.0) during treatment. CR: The disappearance of all target and non-target lesions and normalization of tumor marker level; PR: At least a 30% decrease in the sum of the longest diameter of target lesions, taking as reference the sum of the longest diameter at baseline; SD: Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum of the longest diameter since treatment started.
