Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The number of subjects with adverse events/serious adverse events (Phase Ib) | Throughout phase Ib (approximately 1 year) | Number of patients with adverse events and with serious adverse events including abnormal clinical observations, abnormal ECG parameters, abnormal laboratory assessments and abnormal vital signs that changed from baseline |
| The number of subjects with dose-limiting toxicity (DLT), as defined in the protocol (Phase Ib) | From first dose of study treatment until the end of Cycle 1. | A DLT occurs during Cycle 1 (the DLT assessment period) that is assessed as related to study treatment. |
| Recommended phase II dose (RP2D) (Phase Ib) | Throughout phase Ib (approximately 1 year) | RP2D will be selected upon safety, PK and efficacy data. |
| Objective Response Rate (ORR) (Phase II) | From time of Informed Consent to confirmed progressive disease (approximately 1 year) | Best response until progression, as defined by RECIST 1.1 and PCWG3 |
