Study Endpoints
Primary Endpoints
Objective Response Rate (ORR)
Tumor assessments performed every 6 weeks, up to 30 days after the last dose of dalantercept and/or disease progression, up to approximately 2 years.

ORR is defined as the proportion of patients who met criteria for complete response or partial response. Patients were evaluable for ORR if they had at least one measurable lesion at baseline and at least one disease assessment after baseline. RECIST version 1.1 was used to evaluate efficacy. In addition, patients who developed clinical or radiological progression of disease prior to the scheduled tumor assessment were also considered evaluable for response. The response rate was estimated as the proportion of patients evaluable for response who meet the criteria for complete (CR) and partial response (PR). Per RECIST v1.1 for target lesions and assessed by MRI: complete response (CR), disappearance of all target lesions; partial response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; overall response (OR) = CR + PR.

Secondary Endpoints

Up to 43 days from initiation of treatment.
Progression Free Survival (PFS)
Tumor assessments performed every 6 weeks, up to 30 days after the last dose of dalantercept and/or disease progression, up to approximately 2 years.
