Study Endpoints
Primary Endpoints
Incidence of Adverse Events (Part 1 Only)
Up to 24 months

Safety and tolerability endpoint evaluation via incidence of dose limiting toxicities (DLTs), serious adverse events (SAEs), treatment emergent adverse events (TEAE)

Maximum Tolerated Dose (Part 1 Only)
Up to 24 months

The maximum tolerated dose (MTD) for SW-682, if any, will be based on safety and tolerability during the first 28 days of treatment in Cycle 1.

Recommended Dose for Expansion (Part 1 Only)
Up to 24 months

The recommended dose for expansion (RDE) will be determined based on all safety, tolerability, pharmacokinetics (PK), preliminary antitumor efficacy, and other available data from Part 1 of the study.

Objective Response Rate (Part 2 Only)
Up to 24 months

Objective response rate (ORR), defined as the proportion of participants with confirmed CR or PR using RECIST v1.1, mRECIST for mesothelioma, and/or GCIG CA-125 for ovarian cancer, as applicable, assessed by the investigator.

Secondary Endpoints
Change in plasma and urine concentrations of SW-682
Up to 24 months
Objective Response Rate (Part 1 Only)
Up to 24 months

Phase 1 Dose Escalation Cohorts Ranging in DoseEXPERIMENTALParticipants with advanced solid tumors with or without Hippo pathway mutations will receive SW-682 tablets administered orally in continuous 28-day cycles. SW-682 dosage and frequency of administration will vary by cohort.
Part 2 Dose Expansion Cohort 1EXPERIMENTALParticipants with mesothelioma with or without NF2 mutations will receive SW-682 tablets administered orally in continuous 28-day cycles at the recommended dose for expansion, based on Part 1 data.
Part 2 Dose Expansion Cohort 2EXPERIMENTALParticipants with advanced solid tumors with NF2 mutations will receive SW-682 tablets administered orally in continuous 28-day cycles at the recommended dose for expansion, based on Part 1 data.
Part 2 Dose Expansion Cohort 3EXPERIMENTALParticipants with advanced solid tumors with other Hippo pathway mutations identified during Part 1 (Phase 1a) dose escalation will receive SW-682 tablets administered orally in continuous 28-day cycles at the recommended dose for expansion, based on Part 1 data.
Part 2 Dose Expansion Cohort 4EXPERIMENTALParticipants will receive SW-682 tablets administered orally in continuous 28-day cycles at the recommended dose for expansion, based on Part 1 data, with appropriate combination therapy, identified based on Part 1 data.
