Key Eligibility Criteria
Key Eligibility Criteria Details
  • Expansion Cohort A (ccRCC): Subjects with previously treated advanced RCC with clear cell histology (including those with a sarcomatoid component) who have radiographically progressed following treatment with at least one prior systemic anticancer regimen for inoperable locally advanced or metastatic disease.
  • Expansion Cohorts B and E (nccRCC): Subjects with previously treated advanced RCC with non-clear cell histology who have radiographically progressed following treatment with at least one prior systemic anticancer regimen for inoperable locally advanced or metastatic disease.
  • Expansion Cohorts C and F (HR+ BC): Subjects with breast cancer that is hormone receptor positive (ER+ and/or PR+) and negative for human epidermal growth factor receptor 2 (HER-2) and who have radiographically progressed during or following treatment with at least one prior systemic anticancer regimen for inoperable locally advanced or metastatic disease.
  • Expansion Cohorts D and G (mCRPC): Subjects with metastatic CRPC (adenocarcinoma of the prostate). Neuroendocrine differentiation and other features permitted if adenocarcinoma is the primary histology.
  • Expansion Cohort H (CRC): Subjects with histologically confirmed unresectable, locally advanced, or metastatic adenocarcinoma of the colon or rectum who received prior fluoropyrimidine-containing chemotherapy with oxaliplatin or irinotecan.
  • Expansion Cohort I (UC, Maintenance Therapy): Subjects with histologically confirmed, unresectable, locally advanced or metastatic transitional cell carcinoma of the urothelium (including the renal pelvis, ureter, urinary bladder, or urethra) who received first-line chemotherapy of gemcitabine + cisplatin and/or gemcitabine + carboplatin.
  • Expansion Cohort J (UC, ICI-refractory): Subjects with histologically confirmed, unresectable, locally advanced or metastatic transitional cell carcinoma of the urothelium (including the renal pelvis, ureter, urinary bladder, or urethra) who progressed on or after PD-1/PD-L1 targeting ICI therapy.
  • Expansion Cohort K (UC, platinum-refractory): Subjects with histologically confirmed, unresectable, locally advanced or metastatic transitional cell carcinoma of the urothelium (including the renal pelvis, ureter, urinary bladder, or urethra) who progressed on or after first-line platinum-based combination therapy.
