Study Arms:
- Birabresib 20 mg CRPC Cohort-Part A (Type: EXPERIMENTAL): Participants in the CRPC cohort in Part A of the study received birabresib 20 mg orally (PO), twice a day (BID), in a fasted state for 21 consecutive days per cycle. Participants received birabresib in continuous cycles up to 24 months.
- Birabresib 20 mg NMC Cohort-Part A (Type: EXPERIMENTAL): Participants in the NMC cohort in Part A of the study received birabresib 20 mg PO, BID, in a fasted state for 21 consecutive days per cycle. Participants received birabresib in continuous cycles up to 24 months.
- Birabresib 20 mg TNBC Cohort-Part A (Type: EXPERIMENTAL): Participants in the TNBC cohort in Part A of the study received birabresib 20 mg PO, BID, in a fasted state for 21 consecutive days per cycle. Participants received birabresib in continuous cycles up to 24 months.
- NMC Cohort-Part B (Type: EXPERIMENTAL): Participants (up to 30) in Part B will receive birabresib at one dose level below the dose currently being administered in Part A of the study. Once the recommended Phase 2 dose (RP2D) from Part A is established, participants in Part B will receive birabresib at the RP2D. Participants will continue receiving birabresib at an assigned/adjusted dose level for continuous cycles up to 24 months.

Based on this trial design, predict the completion outcome and termination type (if applicable).

Answer: outcome: terminate
termination_type: lack of efficacy
