|---|---|---|---|---|---|
| Group 1 | Phase I Arm 1 Level 1, PLX038 (PEGylated SN38) 1.3 g/m^2 and Rucaparib 400 mg | Phase I - Participants with solid tumors enrolled to PLX038 (PEGylated SN38) and rucaparib escalation dose levels.~PLX038, every 3 weeks, 1.3 g/m\^2, intravenous (IV); Rucaparib, days 3-19 twice a day (BID), total dose, 400 mg by mouth (PO)~PLX038: Phase I: Dose escalation will follow the classical 3+3 trial design by Fibonacci sequence. Phase II: Maximum tolerated dose (MTD) identified in phase I. PLX038 (PEGylated SN38) will be administered as a 1 hour (-10 minutes / +30 minutes) intravenous (IV) infusion on Day 1 of each cycle (21 days).~Rucaparib: Phase I: Dose escalation will follow the classical 3+3 trial design by Fibonacci sequence. Phase II: Maximum tolerated dose (MTD) identified in phase I. Rucaparib will be given orally at designated dose twice a day on days 5 to 19 of every 21-day cycle. | 1 | 8 | OG000 |
