About CAR-NKG2D

Celyad’s lead immuno-oncology product candidate, CAR-NKG2D, is a chimeric antigen receptor (CAR) T-Cell autologous therapy to treat cancer. The CAR technology developed by Celyad uses human natural killer cell (NK cell) receptor which, unlike traditional CAR technologies such as those targeting the CD19 antigen, has the potential to target ligands present on a broad range of solid tumors and blood cancers.

The research underlying this technology was originally conducted by Dartmouth College Professor Charles Sentman, and has been published in numerous peer-reviewed publications such as Journal of Immunology in 2009, Cancer Research in 2006, and Blood in 2005. CAR-NKG2D has an active Investigational New Drug (IND) application with the FDA for a Phase I clinical trial in certain hematologic cancers.

CAR-NKG2D entered a Phase I clinical trial in April 2015. 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 NKG2D CAR T-cell in certain acute myeloid leukemia and multiple myeloma patients as primary endpoints, with secondary endpoints including clinical efficacy.

About C-Cure®

Celyad’s C-Cure therapy involves taking stem cells from a patient’s own bone marrow and through a proprietary process called Cardiopoiesis, re-programming those cells to become heart cells. The cells, known as cardiopoietic cells, are then injected back into the patient’s heart through a minimally invasive procedure, with the aim of repairing damaged tissue and improving heart function and patient clinical outcomes. C-Cure is the outcome of multiple years of research conducted at Mayo Clinic (Rochester, Minnesota, USA), Celyad (Mont-Saint-Guibert, Belgium) and Cardiovascular Centre in Aalst (Aalst, Belgium).
