Detailed Description
The study will initially comprise 3 parts: dose escalation, backfill, and dose optimization cohorts. The study will follow a stepwise approach, beginning with a typical dose escalation in participants with selected indications of advanced solid tumors. Additional participants will enroll in the backfill part at select dose levels that have been previously cleared for safety by the safety review committee. In dose optimization, participants will be randomized to one of two CR-001 dose levels. All participants will undergo a screening period, a treatment period of up to 2 years, a safety follow-up period, and long-term efficacy and survival follow-up. During the treatment period, participants will undergo clinical and safety assessments including disease assessment scans and blood laboratory safety, pharmacokinetic, and pharmacodynamic assessments. After treatment ends, disease scans will continue until disease progression, and long-term follow-up visits will be conducted by telephone every 3 months.
