Metastatic Castration-resistant Prostate Cancer, Metastatic Solid Tumor, Non-small Cell Lung Cancer, Triple Negative Breast Cancer
Conditions
Brief summary
The study consists of Phase 1a (dose escalation) and Phase 1b (dose expansion). In Phase 1a, sequential cohorts of subjects will receive escalating doses of ITC-6146RO to determine maximum tolerated dose (MTD) and/or optimal biological dose (OBD). In Phase 1b, the recommended phase 2 dose (RP2D) chosen from Phase 1a will be evaluated to further investigate safety, tolerability, pharmacokinetic (PK) and anti-tumor efficacy of ITC-6146RO.
Interventions
ITC-6146RO will be administered as an intravenous (IV) infusion at protocol-specified dose levels and schedules in Phase 1a (dose escalation) and Phase 1b (dose expansion).
