About IPH4102:

KIR3DL2 is an inhibitory receptor of the KIR family, normally expressed on a subset of normal NK cells and specifically expressed in most subtypes of the orphan indication of CTCL. This group of rare cutaneous lymphomas of T lymphocytes has a poor prognosis with few therapeutic options at advanced stages.

IPH4102 is a first-in-class anti-KIR3DL2 humanized cytotoxic antibody, designed to selectively deplete CTCL cancer cells. Potent antitumor properties of IPH4102 were shown against human CTCL cells in vitro and in vivo in a mouse model of KIR3DL2+ tumors, in which IPH4102 reduced tumor growth and improved survival. The efficacy of IPH4102 was further evaluated in laboratory assays using the patients' own natural killer (NK) cells against their primary tumor samples in presence of IPH4102. These latter studies were performed in patients with Sézary Syndrome, the leukemic form of CTCL with the worst prognosis. In these experiments, IPH4102 selectively and efficiently induced killing of the patients' CTCL cells. These results were published in Cancer Research in 2014. A Phase I trial is expected to start in 2015.

IPH4102 was granted orphan drug status in the European Union for the treatment of CTCL. Biomarker tools are being developed in parallel to monitor KIR3DL2 expression in patients.
