"We’re encouraged by the preclinical data from our next-generation JAK2 program being presented at EHA (Free EHA Whitepaper) today," said Andrew Robbins, Cogent’s President and Chief Executive Officer. "This highly selective, potent inhibitor of JAK2 V617F has the potential to address the underlying mutational driver of disease while mitigating off-target hematological effects. We are rapidly advancing this program and remain on track to submit our Investigational New Drug application in 2026."
JAK2 V617F is the most prevalent molecular abnormality in BCR-ABL-negative myeloproliferative neoplasms (MPNs), occurring in approximately 95% of patients with polycythemia vera and 50% of patients with primary myelofibrosis or essential thrombocythemia. The poster highlights CGT1145, a potent inhibitor of the JAK2 V617F mutation with >100x selectivity over JAK2 WT and the JAK1/3 isoforms, along with high oral bioavailability and low clearance across species. CGT1145 has the potential to eradicate JAK2 V617F myeloproliferative neoplasm propagating cells and induce molecular remission with improved hematologic tolerability.
