ICT01

BTN3A activating antibody in clinical trial in immuno-oncology

ICT01

About this program

ICT01 is a humanized, monoclonal antibody that activates γ9δ2 T cells, which are part of the innate immune system that is responsible for immunosurveillance for malignancy and infection, by targeting BTN3A (also known as CD277), a member of the butyrophilin superfamily of immuno-modulatory targets.

BTN3A is expressed on the surface of innate and adaptive immune cells (T cells, B cells and NK cells) and is overexpressed on a number of solid tumors (e.g., bladder, breast, colon, gastric, melanoma, ovarian and prostate) and hematologic cancers (e.g., leukemia & lymphoma). BTN3A appears essential for the activation of the anti-tumor immune response of γ9δ2 T cells.

ICT01 selectively activates circulating γ9δ2 T cells that leads to migration of γ9δ2 T cells out of the circulation and into target tissue (e.g., tumors or infection site).  ICT01 has been shown to have anti-tumor activity against a range of cancers in in vitro and in vivo tumor models.

Clinical development: EVICTION (EValuation of ICT01 in Immuno-ONcology) First-in-human, international, multi-center trial

ImCheck initiated its Phase I/IIa clinical trial with ICT01 in the first quarter of 2020. Named EVICTION (EValuation of ICT01 in Immuno-ONcology), the study is a first-in-human, two-part, open-label clinical trial to assess the safety, tolerability and activity of ICT01 as monotherapy and in combination with an immune checkpoint inhibitor in patients with advanced, relapsed/refractory cancer, including both solid and hematologic tumors that express BTN3A. The trial is an international, multicenter study that will be conducted in Europe with clinical trial applications planned in the United Kingdom and the United States.

ImCheck’s first clinical trial started in 2020

Our entry into the clinic is a significant milestone for ImCheck and is the result of rigorous translational research needed for a first-in-human trial. ICT01 is followed by a robust pipeline of exciting antibody discovery programs addressing novel targets in immuno-oncology and auto-immunity.
