- Healthy Volunteers: f

Study Arms:
- Ixazomib/Carboplatin (Type: EXPERIMENTAL): Accelerated dose-escalation phase with a single-patient cohort per dose level until defined DLT is observed during cycle 1, or until dose level 4 is reached. At this dose level the cohort is expanded to three patients and dose escalation reverts to a conventional 3+3 escalation design.~Intervention (experimental): Ixazomib; po; 3mg escalated to 4mg; day 1, 8, 15 Intervention (backbone): AUC 1.5 escalated to AUC 2.5; day 1, 8, 15

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