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.
