Frequently asked questions about IPH4502

What is IPH4502 used for?

IPH4502 is an investigational small molecule antibody-drug conjugate (ADC) being developed for the treatment of advanced or metastatic solid tumors. It is currently in Phase 1 clinical development and is not yet approved by regulatory authorities.

What does IPH4502 target?

IPH4502 targets Nectin-4, a cell surface protein commonly expressed in various solid tumors. As an antibody-drug conjugate, it is designed to deliver a cytotoxic payload specifically to Nectin-4-expressing cancer cells, potentially reducing damage to healthy tissues.

Who is developing IPH4502?

IPH4502 is being developed by Innate Pharma S.A., a biopharmaceutical company listed on the stock exchange under the ticker symbol IPHA. The company is conducting clinical trials to evaluate the safety and tolerability of this investigational drug.

What phase is IPH4502 in?

IPH4502 is currently in Phase 1 clinical development. It is an investigational drug, meaning it has not been approved by the FDA or any other regulatory agency. The ongoing Phase 1 trial is assessing its safety and tolerability in patients with advanced solid tumors.

What clinical trials is IPH4502 in?

IPH4502 is being evaluated in a Phase 1 clinical trial with the identifier NCT06781983, titled 'Safety and Tolerability of IPH4502 in Patients With Advanced Solid Tumors.' The trial is active but not recruiting, with an estimated enrollment of 145 participants across the United States and France.

Is IPH4502 the same as Nectin-4 ADC?

IPH4502 is a Nectin-4-targeting antibody-drug conjugate (ADC). While it specifically targets Nectin-4, it is a distinct investigational drug candidate developed by Innate Pharma. It is not the same as other Nectin-4 ADCs, such as enfortumab vedotin, which is a different product.
