Filippo Petti, chief executive officer at Celyad, commented, "We are excited to provide additional updates at the upcoming SITC (Free SITC Whitepaper) 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.
