Phase 1/2 Clinical Trial of CP-506 (HAP) in Monotherapy or With Carboplatin or ICI

Summary

A modular, first time in human, open label, multiple dose, accelerated escalation with cohort expansion study of the safety and pharmacokinetics of intravenous infusion of CP-506, a tumor agnostic Hypoxia Activated Prodrug in patients with HRD/FAD solid tumours or tumor types with high incidence of HRD/FAD in monotherapy or in combination with carboplatin or patients with solid tumour and oligoprogressive disease receiving immune checkpoint inhibitors (ICI): a phase I-IIa clinical trial
