Presentation of IPH4102 rationale and phase I design at the cutaneous lymphoma task force meeting of the EORTC

Innate Pharma SA (the “Company” - Euronext Paris: FR0010331421 – IPH) announces that Professor Martine Bagot, Head of the Dermatology Department at the Saint-Louis Hospital in Paris and co-discoverer of the target KIR3DL2, today presented the rationale of IPH4102 for the treatment of CTCL as well as the protocol of the upcoming Phase I trial at the EORTC Cutaneous Lymphoma Task Force meeting in Turin, Italy. IPH4102 is a first-in-class cytotoxic antibody against KIR3DL2, a tumor marker specifically expressed in most subtypes of CTCL. 

Professor Martine Bagot, principal investigator of the Phase I trial, said: “The unmet need in CTCL, notably in Sézary syndrome and transformed mycosis fungoides, the most aggressive forms of CTCL, is very large. Thanks to its novel target specifically expressed by the tumor cells, IPH4102 has a unique potential for being both very effective and well tolerated”. She added: “This Phase I trial includes cohort expansions aiming at an early detection of antitumor activity. We hope that this approach will accelerate the development of IPH4102”.

The Phase I trial is an open label, multicenter study of IPH4102 in patients with relapsed/refractory cutaneous T-cell lymphomas which will be performed in Europe (France, the Netherlands, and the United Kingdom) and in the US. Participating institutions will include several hospitals with internationally recognized expertise: the Saint-Louis Hospital (Paris, France), the MD Anderson Cancer Center (Houston, Texas), the Stanford University Medical Center (Stanford, CA), the Ohio State University (Columbus, OH), the Leiden University Medical Center (Netherlands), and the Guy’s and St Thomas’ Hospital (United Kingdom). Approximately 60 patients with KIR3DL2-positive CTCL having failed at least two prior lines of treatment are expected to be enrolled in a dose-escalation / cohort expansion study. The cohort expansion is expected to be performed in 2 CTCL subtypes displaying the highest expression of KIR3DL2, transformed mycosis fungoides and Sézary syndrome, depending on the findings during the dose escalation part of the study. 

The first patient is expected to be treated in the coming weeks.
