Summary
Brief summary (as posted)
An open-label, two-part Phase I/Ib study of RP12146 in adult patients with locally advanced or metastatic solid tumors. The first part (Part 1) is a Phase I dose-escalation, 3+3 design, open-label, MTD determination study and will enroll patients who have tumors known to harbour DNA repair deficiencies. The second part (Part 2) is a Phase Ib, dose-expansion at the MTD (or optimal dose) and will enroll patients with a confirmed deleterious HRR mutation in their tumor as identified by a central genomics testing laboratory.
