ImCheck Publishes Comprehensive Overview of the Development Results of Its First-in-class Cancer Immunotherapeutic Targeting BTN3A to Activate Gamma-delta T Cells in Science Translational Medicine

  • Publication underscores ImCheck’s pioneering role in Vγ9Vδ2 T cell-based immunotherapy capable of bridging to the adaptive antitumor immune response through a novel family of immune checkpoint targets
  • Evaluation details ICT01’s progression from bench to bedside describing factors that enabled ICT01 to overcome limitations of prior efforts to activate Vγ9Vδ2 T cells for the treatment of cancer

ImCheck Therapeutics announced today the publication of the preclinical to clinical development of its lead immuno-oncology program, ICT01. The publication in the medical journal Science Translational Medicine details ImCheck’s butyrophilin (BTN)-based immuno-oncology approach and positions ImCheck as a pioneer in a nascent field of immunomodulation. ICT01 is a fully-humanized anti-BTN3A monoclonal antibody designed to selectively activate gamma 9 delta 2 (Vγ9Vδ2) T cells through all three isoforms of BTN3A (1/2/3), which are expressed on the surface of innate and adaptive immune cells and overexpressed on the tumor cells of a number of solid and hematologic cancers.

The article, titled “Development of ICT01, a first-in-class, anti-BTN3A antibody for activating Vγ9Vδ2 T cell-mediated anti-tumor immune response” describes the molecular mechanism of how ICT01 activates Vγ9Vδ2 T cells in a pAg-independent and BTN3A isoform-agnostic manner, overcoming the two key limitations of prior efforts to activate Vγ9Vδ2 T cells. In the first-in-human EVICTION Phase I/IIa clinical trial, ICT01 demonstrated selective activation of Vγ9Vδ2 T cells, causing them to rapidly migrate out of the circulation and into tumor tissue. Furthermore, ICT01-activated Vγ9Vδ2 T cells secrete IFNγ and TNFa that expands the anti-tumor immune response by recruiting CD3 and CD8 T cells into tumors.

“This very comprehensive publication describes the bench-to-bedside story of ICT01 and presents in detail ImCheck’s novel and differentiated immunotherapeutic approach,” said Paul Frohna, PharmD, Chief Medical Officer of ImCheck. “ICT01’s unique design circumvents prior limitations of activating Vγ9Vδ2 T cells in cancer patients, making it a promising candidate for the treatment of a broad range of cancers. We look forward to building upon these published results in an upcoming presentation at the SITC 2021 Annual Meeting.”

“Our mission is to apply our scientific expertise and clinical leadership with the BTN superfamily of immunomodulators to bring innovative therapeutics to patients. The publication of these findings in Science Translational Medicine exemplifies our leadership in BTN research as a promising avenue of investigation for cancer immunotherapy and supports the further development of our pipeline of other BTN-targeted programs,” stated Pierre d’Epenoux, Chief Executive Officer of ImCheck Therapeutics.

The publication was authored by ImCheck scientists in collaboration with the laboratory of Prof. Daniel Olive, Professor of Immunology and Director of the Oncology Research Programs at Aix Marseille University and the company’s scientific founder.

Confo Therapeutics Enters Collaborative Agreement With Regeneron

Confo Therapeutics Enters Collaborative Agreement With Regeneron

— Confo will work together with Regeneron to apply its GPCR drug discovery platform to enable functional antibody discovery —

Ghent, Belgium – November 30, 2021 – Confo Therapeutics today announced that it has entered into a collaborative agreement with Regeneron Pharmaceuticals, Inc. whereby Confo’s technology platform, which uses conformationally selective VHH antibodies – ConfoBodies® – to stabilize GPCRs (G protein-coupled receptors) in disease-relevant conformations, will be applied with the goal of enabling the discovery of novel therapeutic antibody drug candidates. The agreement will leverage Confo’s expertise in addressing two GPCR targets for which functional antibodies are needed. Confo will be entitled to an upfront payment, research funding, and potential clinical, regulatory, and commercial payments. Further details regarding the agreement have not been disclosed.

Confo’s ConfoBody-based technology platform aims to overcome the limitations of drug discovery on GPCRs, the largest and most diverse group of membrane receptors targeted by approximately 30% of all commercialized drugs.

“With ten medicines approved by regulatory authorities, Regeneron is regarded in our industry as one of the most effective antibody discovery and development companies, with a successful track record of translating scientific insight into effective and innovative treatments. Working with them underscores the significant potential of our technology platform, in particular our new application to generate antibody drug candidates, and its promise to unveil GPCR drug targets and overcome a range of limitations of current approaches,” commented Cedric Ververken, Chief Executive Officer of Confo Therapeutics.

Christel Menet, Chief Scientific Officer of Confo Therapeutics added: “We value this opportunity to showcase the strength of this new addition to our technology suite and participate in what we hope will be the development of successful new antibody-based therapies. Parallel to this, we continue on our own drug development path, and drive innovative small molecule and biological therapeutics into our own pipeline.”

About Confo Therapeutics

Confo Therapeutics’ unparalleled technology stabilizes functional conformations of GPCRs (G protein-coupled receptors) to uncover a wide range of previously inaccessible drug targets. This platform combined with the pharmacologic and biologic insight it provides, allows Confo to build a multi-indication pipeline of drug candidates with the vision of transforming therapeutic outcomes for patients with severe illnesses lacking disease-modifying treatments. Confo Therapeutics was spun out of Vrije Universiteit Brussel (VUB) and VIB in 2015. Supported by international life-science focused investors and led by an experienced team of entrepreneurial professionals and scientists from successful biopharmaceutical companies, Confo Therapeutics benefits from the rich scientific and innovative ecosystem in Belgium.
