Treatment Details

Interventions

• KZR-261 (Monoclonal Antibodies)

Trial Overview The study tests KZR-261's safety and effectiveness against various solid tumors including melanoma and colorectal cancer. It has two parts: Dose Escalation to find the safe dosage level and Dose Expansion to further evaluate this dose in specific cancers. The goal is also to determine the best Phase 2 dose.

Participant Groups

Group I: KZR-261 with standard therapy: open-label Experimental Treatment 1 Intervention

Part 1 (Dose Escalation) The initial dose cohort of the Dose Escalation will receive 1.8 mg/m2 of KZR-261. Subjects will receive 3 doses in a 28-day cycle. ___________________________________________ Part 2 (Dose Expansion) Following safety review of all Dose Escalation cohorts and determination of the maximum tolerated dose (MTD) or maximum administered dose (MAD), KZR-261 will be evaluated for safety and preliminary efficacy in 4 tumor-specific cohorts and 1 all-tumor cohort to determine the recommended phase 2 dose (RP2D). The 4 tumor-specific cohorts will include: * melanoma (including uveal melanoma) * colorectal cancer * prostate cancer * mesothelioma
