Celyad to Present Update from CYAD-101 for Advanced Colorectal Cancer and Next-Generation shRNA Platform at 2020 ASCO Virtual Scientific Program

• Two accepted abstracts will be presented virtually in a prerecorded poster presentation
  
  

MONT-SAINT-GUIBERT, Belgium, April 30, 2020 (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 two abstracts have been accepted for poster presentation at the 2020 American Society for Clinical Oncology (ASCO) Virtual Scientific Program, which will be held from May 29-31, 2020. The first poster will focus on CYAD-101, the company’s first-in-class, non-gene edited, allogeneic CAR-T program for the treatment of metastatic colorectal cancer, while the second poster will highlight the company’s next-generation, short-hairpin RNA (shRNA) technology platform used in the company’s CYAD-200 series of allogeneic CAR-T product candidates.  

Filippo Petti, chief executive officer of Celyad, noted, “We’re excited to be sharing an update at the upcoming ASCO Annual Meeting on our industry-leading allogeneic CAR-T candidate CYAD-101 for the treatment of solid tumors, as well as providing an important update on progress with our next-generation shRNA platform, which allows for knockdown of multiple genes without the use of gene-editing in a single CAR-T construct."

The abstracts published today will be available on May 13 on . Following presentation at the meeting, the posters will be available on .

About CYAD-101

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 signaling of the TCR complex, which is responsible for graft-versus host disease (GvHD).

About shRNA Platform and CYAD-200 Series

The Company is focused on the development of its proprietary non-gene edited allogeneic short hairpin RNA (shRNA) SMARTvector technology platform through the CYAD-200 series of product candidates. The Company is currently evaluating several shRNA-based allogeneic CAR-T candidates, including CYAD-211, an allogeneic CAR-T therapy targeting B-cell maturation antigen (BCMA) for the treatment of relapsed/refractory multiple myeloma.

About Colorectal Cancer

Colorectal cancer is the third most common type of cancer among both men and women worldwide and is the fourth most common 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 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%.

About Celyad

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.
