| Primary | Objective Response Rate (ORR) Using Response Evaluation Criteria for Solid Tumors (RECIST 1.1) | Objective Response Rate (ORR) is defined as the number of patients achieving a complete response (CR) or partial response (PR) based on RECIST 1.1 criteria. CR = disappearance of all target lesions, PR is =>30% decrease in sum of diameters of target lesions. Subjects who discontinue due to clinical progression prior to post-baseline tumor assessments were considered as non-responders. | | Posted | | Count of Participants | | Participants | | 27 months | | | | ID | Title | Description |

Per RECIST 1.1 criteria, CR = disappearance of all target lesions, Partial Response (PR) is =>30% decrease in sum of diameters of target lesions, Progressive Disease (PD) is >20% increase in sum of diameters of target lesions. | There were no responses (PR or CR) observed in Arm A; therefore, the number of analyzed participants is zero. 3 participants achieved response in Arm B. | Posted | | Median | Full Range | months | | 27 months | | | | ID | Title | Description |
