Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a first-in-human, open-label, multicenter, Phase 1 study to evaluate the safety, tolerability and preliminary efficacy of IPH4502 and to determine the recommended Phase 2 dose (RP2D) in advanced solid tumors that are known to express Nectin-4

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a first-in-human, open-label, multicenter, single-arm Phase 1 study, with a part 1 dose escalation guided by a Bayesian optimal interval design with backfilling (BOIN-BF), followed by a part 2 dose optimization in up to 2 selected indications. This study is to measure the safety, tolerability, pharmacokinetics, and preliminary efficacy of escalating doses of IPH4502 in patients with advanced solid tumors that are known to express Nectin-4.
