SW-682 in Advanced Solid Tumors

Key Inclusion Criteria:

• Histologically confirmed, metastatic, or unresectable solid cancer that has either not responded to or progressed during or after appropriate prior systemic anticancer therapy including chemotherapy, immunotherapy, radiation therapy, or appropriate targeted therapy, or for which there is no treatment available or prior SOC therapy was not tolerated and for which there is no further SOC treatment available

• Part 1: must have one of the following:

  • Mesothelioma with or without NF2 mutations
  • Advanced solid tumors with NF2 mutations
  • Advanced solid tumors with other Hippo pathway mutations or fusions (e.g., FAT1, LATS1/2, YAP fusions; WWTR1-CAMTA1 in EHE).

• Part 2: must have the tumor histology and oncogenic mutation or genomic aberration specific to each dose expansion cohort defined below:

  • Cohort 1: Participants with mesothelioma with or without NF2 mutations
  • Cohort 2: Participants with advanced solid tumors with NF2 mutations
  • Cohort 3: Participants with advanced solid tumors with other Hippo pathway mutations identified during Part 1 (Phase 1a) dose escalation
  • Cohort 4: SW-682 with appropriate combination therapy.

• In both parts, participants should have known oncogenic mutation identified by Next Generation Sequencing or local assay

• Must have archival tumor tissue or agree to a fresh tumor biopsy at screening

• Measurable disease per RECIST 1.1

• Eastern Cooperative Oncology Group (ECOG) performance status of ≤1

• Adequate bone marrow, kidney, hepatic, and coagulation function

Key Exclusion Criteria:

• Evidence of symptomatic CNS metastases, leptomeningeal carcinomatosis, or untreated spinal cord compression
• Clinically significant cardiac disease or abnormal cardiac parameters
• Preexistence or inheritance of a familial renal syndrome
• Concomitant non-anti-arrhythmic medications that are known to prolong the QTc interval
• Concomitant medicines that are known strong/moderate inhibitors or inducers of cytochrome P450 3A4 (CYP3A4) and/or CYP1A2 within 14 days or 5 half-lives before the first dose of study treatment
• Concomitant medicines that are known sensitive substrates of CYP3A4, CYP2C19, CYP2D6, CYP1A2, and/or CYP2B6 within 14 days or 5 half-lives before the first dose of study treatment
• Concomitant medicines that are known sensitive substrates of PGP, BCRP, OATP1B1, OATP1B3, OAT1, OAT3, MATE1, MATE2-K, OCT2
• Clinically significant active infection (bacterial, fungal, or viral)
