MONT-SAINT-GUIBERT, Belgium, April 17, 2019 (GLOBE NEWSWIRE) -- Celyad (Euronext Brussels and Paris, and Nasdaq: CYAD), a clinical-stage biopharmaceutical company focused on the development of CAR-T cell-based therapies, today announced that clinical data from the SHRINK and alloSHRINK Phase 1 trials, evaluating the safety of NKG2D-based autologous and allogeneic CAR-T candidates, CYAD-01 and CYAD-101, respectively, will be presented at the upcoming European Society for Medical Oncology (ESMO) 21st World Congress on Gastrointestinal Cancer (WCGIC) to be held on July 3-6, 2019, in Barcelona, Spain.
“We are delighted for the opportunity to present updated data at the upcoming WCGIC from both our autologous and allogeneic NKG2D-based clinical candidates for the treatment of refractory metastatic colorectal cancer,” noted Frédéric Lehmann, Head of Global Clinical Development and Medical Affairs at Celyad. “We continue to build upon our clinical experience in the treatment of solid tumors with these novel immunotherapies and the oral presentation at WCGIC represents a special milestone to highlight preliminary data from the industry’s first trial investigating an ‘off-the-shelf‘ CAR-T candidate for the treatment of solid tumors. In addition, the comparable trial designs between SHRINK and alloSHRINK as well as the similar CAR constructs provide insight into autologous and allogeneic approaches in an advanced solid tumor indication.”
Abstract #631: Phase 1 studies assessing the safety and clinical activity of autologous and allogeneic NKG2D-based CAR-T therapy in metastatic colorectal cancer
Session: Short Oral Presentation
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 (donor derived) CAR-T therapy that co-expresses the NKG2D CAR of CYAD-01 and the novel inhibitory peptide TIM (T cell receptor [TCR] Inhibiting Molecule). The expression of TIM reduces signalling of the TCR complex which is responsible for Graft versus Host Disease (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 (combination of 5-fluorouracil, leucovorin and oxaliplatin) chemotherapy in patients with metastatic colorectal cancer (mCRC). Patients will receive six cycles of FOLFOX 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 refractory 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.
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 autologous and allogeneic platforms have the potential to treat a broad range of solid and hematologic tumors. After having evaluated safety, its lead oncology autologous CAR-T investigational therapy CYAD-01 (CAR-T NKG2D) is now currently being evaluated in several Phase I clinical trials to assess the clinical activity of multiple administrations of autologous CYAD-01 cells in solid cancer (metastatic colorectal cancer) and hematological tumors (acute myeloid leukemia) with or without being concurrently administered with standard-of-care treatments (preconditioning chemotherapy). Concomitantly, Celyad is developing CYAD-101, first-in-class, investigational, non-gene edited, allogeneic (donor derived) CAR-T therapy co-expressing the CAR-T NKG2D and the novel inhibitory peptide TIM (T cell receptor [TCR] Inhibiting Molecule). The expression of TIM reduces signaling of the TCR complex and could therefore potentially reduce or eliminate Graft versus Host Disease (GvHD). CYAD-101 is being evaluated in a Phase I trial for the treatment of patients with mCRC. Preliminary results are expected in second half of 2019. 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.
