MONT-SAINT-GUIBERT, Belgium, Nov. 11, 2019 (GLOBE NEWSWIRE) -- Celyad (Euronext Brussels and Paris, and Nasdaq: CYAD), a clinical-stage biopharmaceutical company focused on the development of CAR-T cell therapies, today announced highlights from the company's NKG2D-based CAR-T clinical candidates for the treatment of metastatic colorectal cancer (mCRC), including its novel, off-the-shelf cell therapy CYAD-101 and alloSHRINK dose-escalation Phase 1 trial. Results were presented at the Society for Immunotherapy of Cancer (SITC) 34th Annual Meeting, held in Washington D.C. from November 6-10, 2019.
Dr. Frédéric Lehmann, VP of Clinical Development & Medical Affairs at Celyad, commented, "We are encouraged by the latest results from the alloSHRINK trial in metastatic colorectal cancer patients previously exposed to oxaliplatin- and irinotecan-based chemotherapies, including the tolerability profile and early antitumor activity of CYAD-101 with prior FOLFOX preconditioning chemotherapy. In particular, the lack of clinical and laboratory evidence of graft-versus-host-disease for CYAD-101, which incorporates our proprietary T-cell receptor inhibitory molecule to reduce signaling of the TCR complex, establishes proof-of-concept for this industry-leading, off-the-shelf CAR-T approach. In addition, any host-versus-graft reaction against the allogeneic CAR-T product candidate appears to be controlled by the non-myeloablativeFOLFOX chemotherapy. Overall, these encouraging data from the alloSHRINK trial warrant further evaluation of CYAD-101."
Filippo Petti, CEO of Celyad, stated, "Treatment of advanced metastatic colorectal cancer patients beyond the second line of metastatic chemotherapy remains a high unmet medical need. Our confidence in CYAD-101 has continued to build as data from the alloSHRINK trial have emerged over the past year. We look forward to the planned expansion segment of the alloSHRINK trial to further evaluate the CAR-T product candidate for refractory mCRC patients as we continue to execute on the company's vision for the treatment of patients with advanced solid tumors with allogeneic CAR-T therapies."

About CYAD-101 and alloSHRINK Trial
CYAD-101 is an investigational, non-gene edited, allogeneic (healthy donor derived) CAR-T therapy engineered to co-express a chimeric antigen receptor (CAR) based on NKG2D, a receptor expressed on natural killer (NK) cells that binds to eight stress-induced ligands and the novel inhibitory peptide TIM (T cell receptor [TCR] Inhibitory Molecule). The expression of TIM reduces signalling of the TCR complex, which is responsible for GvHD.
alloSHRINK is an open-label, dose-escalation Phase 1 trial assessing the safety and clinical activity of three consecutive administration of CYAD-101 every two weeks administered concurrently with FOLFOX (combination of 5-fluorouracil, leucovorin and oxaliplatin) chemotherapy in patients with refractory mCRC.
About Colorectal Cancer
Colorectal cancer is the third most common type of cancer among both men and women worldwide and is the fourth in terms of mortality. In 2018, approximately 1.8 million people were diagnosed with colorectal cancer with about 140,000 and 500,000 diagnoses in the United States and Europe, respectively. According to data from the American Society of Clinical Oncology (ASCO), approximately 40% of patients are diagnosed with early-stage, localized-stage disease. The five-year survival rate of localized disease is approximately 90%. In patients where the cancer has spread to distant parts of the body, as in metastatic colorectal cancer, the five-year survival rate drops to approximately 15%.
Celyad is a clinical-stage biopharmaceutical company focused on the development of specialized CAR-T cell-based product candidates and utilizes its expertise in cell engineering to target cancer. Celyad's CAR-T cell platform has the potential to treat a broad range of solid and hematologic tumors. The company's lead clinical candidate, CYAD-01, an autologous NKG2D-based CAR-T therapy, is currently being evaluated in several Phase 1 clinical trials to assess safety and clinical activity for the treatment of hematological malignancies, such as acute myeloid leukemia, and solid cancers, such as metastatic colorectal cancer. Celyad is also developing CYAD-101, an investigational, non-gene edited, allogeneic (donor derived) NKG2D-based CAR-T therapy, which is currently being evaluated in a Phase 1 trial for the treatment of patients with metastatic colorectal cancer. Celyad was founded in 2007 and is based in Mont-Saint-Guibert, Belgium, and New York, NY. Celyad's ordinary shares are listed on the Euronext Brussels and Euronext Paris exchanges, and its American Depository Shares are listed on the Nasdaq Global Market, all under the ticker symbol CYAD.
