Is this trial a fit for you?

Likely a good fit

Adults with measurable locally advanced or metastatic solid tumors (for example hepatocellular carcinoma, biliary tract, endometrial, cervical, ovarian, gastric/gastroesophageal, colorectal, or non-small cell lung cancer), ECOG 0–1, life expectancy ≥3 months, adequate organ function, and who are progressing on or ineligible for standard therapies are ideal candidates.

Probably not a fit

Patients with poor performance status (ECOG ≥2), life expectancy under three months, inadequate organ function, other active malignancies within the past three years, or contraindications to required procedures are unlikely to benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

The trial tests CR-001 as a monotherapy in adults with locally advanced or metastatic solid tumors through Phase 1 dose-finding and Phase 2 dose optimization stages. It begins with dose escalation to identify the maximum tolerated or optimal biologic dose, includes backfill cohorts at dose levels cleared for safety, and then randomizes participants in dose optimization to one of two CR-001 dose levels. Participants receive up to two years of treatment with regular safety labs, pharmacokinetic and pharmacodynamic sampling, and disease assessment scans, with scans continuing after treatment until disease progression. Long-term efficacy and survival follow-up are conducted by telephone every three months.

Why it matters

Potential benefit: If successful, CR-001 could provide a new treatment option with an acceptable safety profile for patients whose advanced solid tumors have progressed on or are unsuitable for standard therapies.

How similar studies have gone: Other therapies targeting PD-1 and VEGF pathways have shown benefit in several tumor types, but CR-001 as a monotherapy in this early-phase setting is novel and has not yet shown proven clinical benefit.
