Innate Pharma doses first patient in IPH4502 study

Innate Pharma (IPHA) announced the first patient was dosed in its Phase 1 study, investigating the safety and tolerability of IPH4502, an Antibody-Drug Conjugate, in patients with advanced solid tumors known to express Nectin-4. IPH4502 is a novel and differentiated topoisomerase I inhibitor ADC designed to precisely target Nectin-4, a cell adhesion molecule that is overexpressed in several types of solid tumors, including urothelial carcinoma, breast cancer, non-small cell lung cancer or gastro-intestinal cancer. IPH4502 targets tumors with a wide range of Nectin-4 expression, supporting its development beyond UC. IPH4502 differentiated topoisomerase I inhibitor payload supports its potential in patients with tumors resistant to MMAE-ADC. The Phase 1, open-label, multi-center study, includes a Part 1 Dose Escalation and a Part 2 Dose Optimization, and will assess the safety, tolerability, and preliminary efficacy of IPH4502 as a single agent in advanced solid tumors known to express Nectin-4, including but not limited to urothelial carcinoma, non-small cell lung, breast, ovarian, gastric, esophageal, and colorectal cancers. The study plans to enroll approximately 105 patients.
