Mont-Saint-Guibert, Belgium – Celyad (Euronext Brussels and Paris, and NASDAQ: CYAD), a leader in the discovery and development of engineered cell therapies, with clinical programs in cardiovascular diseases and immuno-oncology, today announced that an oral presentation titled “Validation of Manufacturing NKG2D Chimeric Antigen Receptor T Cells for a First-in Human Trial in AML/MDS and Multiple Myeloma” will be made at the American Society of Gene & Cell Therapy (ASGCT) 19th Annual Meeting May 4-7 in Washington DC.
Dr. Frédéric Lehmann, Head of Immuno-Oncology at Celyad: “We are pleased that the application to present the validation of our cell manufacturing process was selected for an oral presentation. It highlights the importance and interest in our NKR-2 clinical program marking a positive step forward. This technology has great potential and we are looking forward to completing the Phase I.”
About Celyad’s NKR-T program
NKR stands for Natural Killer Receptor. NKG2D CAR T-cells are now called NKR-2 T-cells and the product development name is NKR-2.
Existing CAR-T cells are engineered using constructs encoding an antibody single chain variable fragment, the signaling domain of CD3 zeta and one or more co-stimulatory domain(s). In contrast to existing CAR-T cells, Celyad’s lead immuno-oncology product candidate, NKR-2, is a T-Cell encoded to express the human Natural Killer activating receptor, NKG2D. Using the human Natural Killer cell receptor, unlike traditional CAR technologies, has the potential to:
Bind to 8 different ligands that are expressed by a vast majority of cancer cells, both hemaetological and solid malignancies.
Target and kill tumors as well as the blood vessels that feed them and also express the ligands of the NKG2D receptor.
Target and kill the inhibitory mechanisms preventing the tumor from evading the immune system.
Induces adaptive auto-immune response thanks to the creation of a long term cell memory against the targeted tumor.
The research underlying this technology was originally conducted by Dartmouth College Professor Charles Sentman, and has been published in numerous peer-reviewed publications. NKR-2 has an active Investigational New Drug (IND) application with the FDA for a Phase I clinical trial. The full data readout from the Phase I dose escalation trial is expected in mid-2016.
The trial is designed to assess the safety and feasibility of NKR-2 in acute myeloid leukemia and multiple myeloma patients, with secondary endpoints including clinical activity. The safety follow-up period post-infusion has been decreased to 21 days after approval by the U.S. Food and Drug Administration (FDA) and Institutional Review Board (IRB).
