Innate Pharma Announces First Patient Dosed in Phase 1 Study of Its Nectin-4 Targeting Antibody Drug Conjugate IPH4502 in Selected Advanced Solid Tumors
IPH4502 is a novel and differentiated topoisomerase I inhibitor ADC conjugated to exatecan targeting Nectin-4
MARSEILLE, France, January 27, 2025--(BUSINESS WIRE)--Regulatory News:
Innate Pharma SA (Euronext Paris: IPH; Nasdaq: IPHA) ("Innate" or the "Company") today announced the first patient was dosed in its Phase 1 study (NCT06781983), investigating the safety and tolerability of IPH4502, an innovative Antibody-Drug Conjugate (ADC), 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 (UC), 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.
"We are thrilled to initiate the Phase 1 study with IPH4502, a promising therapy for patients with advanced solid tumors known to express Nectin-4," said Dr Shiraj Sen,Medical Oncologist and Phase 1 Investigator, Director of Clinical Research, NEXT Oncology-Dallas. "IPH4502 is uniquely designed to target tumors with both high and low expression of Nectin-4, offering hope for improved outcomes in a population where effective treatment options are limited, and relapses occur frequently. This study represents an important step forward in advancing innovative care for these patients."
"The initiation of this Phase 1 trial represents a significant milestone for Innate Pharma as our clinical stage pipeline now includes targeted ADCs. We are optimistic about the potential of IPH4502 to address unmet needs in the treatment of advanced solid tumors, with a well differentiated Nectin-4 targeting and the promise of ADC technology to provide a new therapeutic option for patients," added Dr Sonia Quaratino, Chief Medical Officer at Innate Pharma.
IPH4502 is a novel topoisomerase I inhibitor Antibody Drug Conjugate (ADC) conjugated to exatecan targeting Nectin-4. It is currently investigated in a Phase 1 trial in advanced solid tumors expressing Nectin-4.
Nectin-4 is a cell membrane adhesion protein overexpressed in several solid tumors, including urothelial, breast, esophageal, lung, ovarian, and pancreatic cancers, with limited expression in normal tissues.
In non-clinical models, IPH45 is well tolerated and shows anti-tumor activity in vitro and in vivo.
