MONT-SAINT-GUIBERT, Belgium--()--Regulatory News:

Celyad (Brussels:CYAD) (Paris:CYAD) (NASDAQ:CYAD), a clinical-stage biopharmaceutical company focused on the development of CAR-T cell therapies, today announced that abstracts highlighting clinical and translational research data from the company’s pipeline of NKG2D-based candidates focused on the treatment of metastatic colorectal cancer (mCRC), including the allogeneic cell therapy CYAD-101, were published today ahead of the Society for Immunotherapy of Cancer’s 34th Annual Meeting (SITC).

Filippo Petti, chief executive officer at Celyad, commented,We are excited to provide additional updates at the upcoming SITC annual meeting from our current CAR-T program in metastatic colorectal cancer, including translational data from multiple approaches we have pursued with our NKG2D-based candidates for the treatment of the disease. Over the past few years, we have treated over thirty metastatic colorectal cancer patients within the program assessing various conditions. We continue to be encouraged by the results and prospects for the program and, in particular, from clinical data of our lead allogeneic candidate CYAD-101 where we have observed an absence of graft versus host disease and preliminary signals of clinical activity in a refractory, difficult to treat patient population.”

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 are planned to receive consecutive cycles of FOLFOX (combination of 5-fluorouracil, leucovorin and oxaliplatin) chemotherapy every two weeks concurrently with multiple administrations of CYAD-01.

alloSHRINK is an open-label, dose-escalation Phase 1 trial assessing the safety and clinical activity of three consecutive administrations of CYAD-101 every 2 weeks administered concurrently with FOLFOX chemotherapy in patients with refractory mCRC.

In particular it should be noted that the data summarized above are preliminary in nature. There is limited data concerning safety and clinical activity following treatment with the CYAD-01, CYAD-101 and CYAD-02 drug product candidates. Our therapeutic candidates manufactured using our OptimAb process have not yet been evaluated in clinical trials. Prior clinical and preclinical results may not be repeated or observed in ongoing or future clinical studies involving the CYAD-01 and CYAD-101 drug product candidates. These forward-looking statements are further qualified by important factors and risks, which could cause actual results to differ materially from those in the forward-looking statements, including statements about: the initiation, timing, progress and results of our preclinical studies and clinical trials, and our research and development programs; our ability to advance drug product candidates into, and successfully complete, clinical trials; our ability to successfully manufacture drug product for our clinical trials, including with our OptimAb manufacturing process and with respect to manufacturing drug product with the desired number of T cells under our clinical trial protocols; our reliance on the success of our drug product candidates, including our dependence on the regulatory approval of CYAD-01, CYAD-101 and CYAD-02 in the United States and Europe and subsequent commercial success of CYAD-01, CYAD-101 and CYAD-02, both of which may never occur; the timing or likelihood of regulatory filings and approvals; our ability to develop sales and marketing capabilities; the commercialization of our drug product candidates, if approved; the pricing and reimbursement of our drug product candidates, if approved; the implementation of our business model, strategic plans for our business, drug product candidates and technology; the scope of protection we are able to establish and maintain for intellectual property rights covering our drug product candidates and technology; our ability to operate our business without infringing, misappropriating or otherwise violating the intellectual property rights and proprietary technology of third parties; cost associated with enforcing or defending intellectual property infringement, misappropriation or violation; product liability; and other claims; regulatory development in the United States, the European Union, and other jurisdictions; estimates of our expenses, future revenues, capital requirements and our needs for additional financing; the potential benefits of strategic collaboration agreements and our ability to maintain and enter into strategic arrangements; our ability to maintain and establish collaborations or obtain additional grant funding; the rate and degree of market acceptance of our drug product candidates, if approved; our financial performance; developments relating to our competitors and our industry, including competing therapies and statements regarding future revenue, hiring plans, expenses, capital expenditures, capital requirements and share performance.
