MONT-SAINT-GUIBERT, Belgium, July 05, 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 that Professor Dr. Eric Van Cutsem from the University Hospital of Leuven (Universitair Ziekenhuis Leuven, UZ Leuven) presented preliminary interim data from the ongoing SHRINK and alloSHRINK Phase 1 trials assessing safety and clinical activity of the NKG2D-based CAR-T therapies CYAD-01 (autologous) and CYAD-101 (allogeneic) for the treatment of metastatic colorectal cancer (mCRC) at the European Society for Medical Oncology (ESMO) 21st World Congress on Gastrointestinal Cancer (WCGIC). Following the oral and poster presentations at WCGIC, Celyad’s management team will host a conference call to discuss the initial clinical results from the SHRINK and alloSHRINK trials.
“We are encouraged by these initial results showing increased levels of cell engraftment of the non-gene edited allogeneic CAR-T candidate CYAD-101, and that following treatment with CYAD-101 we did not observe any evidence of graft versus host disease, our foremost concern with the allogeneic therapy” commented Professor Dr. Eric Van Cutsem, Gastrointestinal Oncologist at the University Hospital of Leuven. “In addition, anti-tumor activity has been observed with both the autologous CYAD-01 and allogeneic CYAD-101 candidates, in heavily pre-treated metastatic colorectal cancer patients who have received prior FOLFOX chemotherapy, providing confidence into this potential combination approach of CAR-T therapy with standard-of-care chemotherapy.”
Dr. Frédéric Lehmann, VP of Clinical Development & Medical Affairs at Celyad, commented “We are excited to share data on the first-in-class non-gene edited allogeneic CAR-T therapy CYAD-101 in metastatic colorectal cancer at ESMO GI in Barcelona. Professor Dr Van Cutsem gave us the great honor to share compelling clinical data for this novel class of NKG2D-based CAR-T therapies and the ability of the company’s novel T cell receptor Inhibiting Molecule, TIM, to reduce signalling of the TCR complex.”

Background on CYAD-01 and CYAD-101
CYAD-01 is an investigational CAR-T therapy in which a patient's T cells are engineered to express a chimeric antigen receptor (CAR) based on NKG2D, a receptor expressed on natural killer (NK) cells that binds to eight stress-induced ligands expressed on tumor cells. CYAD-101 is an investigational, non-gene edited, allogeneic (healthy donor derived) CAR-T therapy that co-expresses the NKG2D CAR of CYAD-01 and the novel inhibitory peptide TIM. The expression of TIM reduces signalling of the TCR complex, which is responsible for GvHD.
Background on SHRINK and alloSHRINK Trials
SHRINK is an open-label, dose-escalation Phase 1 trial assessing the safety and activity of CYAD-01 administered concurrently with FOLFOX chemotherapy in patients with metastatic colorectal cancer (mCRC). Patients will receive six cycles of FOLFOX (combination of 5-fluorouracil, leucovorin and oxaliplatin) chemotherapy every two weeks and three administrations of CYAD-01 every two weeks.
alloSHRINK is an open-label, dose-escalation Phase 1 trial assessing the safety and clinical activity of CYAD-101 administered concurrently with FOLFOX chemotherapy in patients with unresectable mCRC. Similar to the SHRINK trial for CYAD-01, patients will receive six cycles of FOLFOX chemotherapy every two weeks and three administrations of CYAD-101 every two weeks.
Background on THINK CyFlu Cohort
In February 2018, the THINK trial was amended to include a cohort known as THINK CyFlu. The cohort evaluated a single injection of CYAD-01 following treatment with the standard preconditioning regimen of cyclophosphamide (300 mg/m²) and fludarabine (30 mg/m²), or CyFlu.
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.
