(Shattuck) (Nasdaq: STTK), a biotechnology company pioneering the development of novel therapeutics targeting tumor necrosis factor (TNF) superfamily receptors for the treatment of patients with cancer and chronic immune-related diseases, today announced a strategic pipeline prioritization to include the discontinuation of its clinical program, SL-172154. The Company will turn its focus to SL-325, its DR3 antagonist antibody, and plans initial clinical development in patients with IBD, where TL1A/DR3 blocking antibodies have demonstrated compelling monotherapy efficacy. “We are disappointed that the promising complete remission rates we previously shared from our Phase 1 clinical trial did not translate to clinically meaningful improvements in median overall survival for TP53m AML and HR-MDS patients treated with SL-172154 in combination with azacitidine. We thank our clinical team and investigators for conducting an excellent clinical study, yet we must accept this result as it stands and move on to other opportunities with a higher probability of success,” said Taylor Schreiber, M.D., Ph.D., Chief Executive Officer of Shattuck. Dr. Schreiber continued, “We are announcing a strategic shift to focus on SL-325, a DR3 antagonist antibody designed to achieve a more complete blockade of the clinically validated TL1A/DR3 signaling pathway. We believe SL-325 could be a first-in-class DR3 receptor blocking antibody, and that this approach will prove more potent than blocking TL1A, for many of the same reasons that blocking PD-1 has proven more potent than blocking PD-L1.
