Celyad Announces Registration of the first patient in the Belgian THINK trial
- A first colorectal cancer patient has been registered at Institut Jules Bordet.
- CAR-T NKR-2 processing started yesterday at Celyad’s manufacturing facility, in Mont-Saint-Guibert.
Mont-Saint-Guibert, Belgium - Celyad (Euronext Brussels and Paris, and NASDAQ: CYAD), a leader in the discovery and development of engineered cell-based therapies, today announced that the first patient of the Therapeutic Immunotherapy with NKR-2 (THINK) trial started cell processing in Belgium. Blood was collected from this patient and first CAR-T NKR-2 dose level infusion (3x108 cells) is expected in January 2017.
“We are pleased to announce that the first patient has been registered in our Belgian Phase Ib trial of CAR-T NKR-2. After witnessing evidence of activity in our initial safety studies, we are enthusiastic about reporting data from this trial in 2017. We look forward to expanding the trial to U.S.-based institutions and I would like to thank our clinical partners, and the Celyad team for enabling this milestone.” “This is an important moment for Celyad. The THINK trial is aimed to demonstrate that CAR-T NKR-2 cells can deeply transform the way we treat cancer patients. The team keeps on showing its awe-inspiring ability to deliver in Research and Development, and the Company has now reached a cardinal inflection point to emerge as a key player in the CAR-T space.”
Christian HomsyCEO of Celyad
About the THINK trial
THINK (THerapeutic Immunotherapy with NKR-2) is a multinational (EU/US) open-label Phase Ib study to assess the safety and clinical activity of multiple administrations of autologous CAR-T NKR-2 cells in seven refractory cancers, including five solid tumors (colorectal, ovarian, bladder, triple-negative breast and pancreatic cancers) and two hematological tumors (acute myeloid leukemia and multiple myeloma).
The trial will test three dose levels adjusted to body weight: up to 3x108, 1x109 and 3x109 CAR-T NKR-2 cells. At each dose, the patients will receive three successive administrations, two weeks apart, of CAR-T NKR-2 cells. The dose escalation part of the study will enroll up to 24 patients while the extension phase would enroll 86 additional patients.
Celyad is a clinical-stage biopharmaceutical company focused on the development of specialized cell-based therapies. The Company utilizes its expertise in cell engineering to target severe diseases with significant unmet need, including cancer. Celyad’s Natural Killer Receptor based T-Cell (NKR-T) platform has the potential to treat a broad range of solid and liquid tumors. Its lead oncology candidate, the CAR-T NKR-2, has been evaluated in a single dose escalation Phase I clinical trial to assess the safety and feasibility of CAR-T NKR-2 cells in patients suffering from AML or MM. This Phase I study was successfully completed in September 2016. Celyad was founded in 2007 and is based in Mont-Saint-Guibert, Belgium, and Boston, Massachusetts. Celyad’s ordinary shares are listed on the Euronext Brussels and Euronext Paris exchanges, and its American Depository Shares are listed on NASDAQ Global Market, all under the ticker symbol CYAD.

About Celyad’s NKR-T Cell Platform
Celyad is developing a unique CAR-T cell platform, using Natural Killer Receptor (NKR) transduced on to T lymphocytes. The platform targets a wide range of solid and hematological tumors. Unlike traditional CAR-T cell therapy, which target only one tumor antigen, Natural Killer (NK) cell receptors enable a single receptor to recognize multiple tumor antigens.
Celyad’s lead candidate, CAR-T NKR-2, is a CAR-T-Cell engineered to express the human NK receptor, NKG2D, which is an activating receptor that triggers cell killing through the binding of NKG2D to any of eight naturally occurring ligands that are known to be overexpressed on more than 80% of tumors.
Preclinical results indicate that CAR- T NKR-2 has multiple mechanisms of actions and goes beyond direct killing by signifying that its encoded T-Cells attack the tumor cells, inhibits the mechanisms that enable tumors to evade the immune system, activates and recruits anti-tumor immune cells and disrupts the blood supply to the tumor. These mechanisms promote the induction of adaptive immunity, meaning the body develops a long-term cell immune memory against specific tumor antigens of the targeted tumor.
In contrast to traditional CAR-T therapeutic approaches, and based on strong preclinical evidence, Celyad’s current NKR-2 program does not employ patient lymphodepleting pre-conditioning, thereby avoiding the toxicities associated with chemotherapy and allowing the immune system to remain intact.
Celyad is developing both autologous and allogeneic CAR-T NKR-2 administrations. For autologous CAR-T NKR-2, Celyad collects the patient’s own T-Cells and engineers them to express NKG2D in order to target cancer cells effectively. Celyad’s allogeneic platform engineers the T-Cells of healthy donors, that also express TCR Inhibitory Molecules (TIMs), to avoid having the engineered donor cells be rejected by the patient’s normal tissues (also called Graft vs. Host Disease).
The preclinical research underlying this technology was originally conducted at Dartmouth College by Dr. Charles Sentman and has been published extensively in peer-reviewed publications.
