Tumor assessments were performed at screening, Cycle 3 Day 1, then every 2 cycles through Cycle 13, then every 3 cycles thereafter up to approximately 4 years. Each cycle is 28 days.

What was measured

A complete response is defined as complete disappearance of all target lesions. A partial response is ≥10% decrease tumor size at computed tomography (CT) or ≥15% decrease in tumor attenuation at computed tomography (CT) and no new lesions. The response rate is defined as complete response plus partial response.

Analysis population: Patients enrolled in Part 1 or Part 2 with a starting dose of 300 or 400 mg
