Aptose to Hold Clinical Update and Data Review of AML Drug Tuspetinib on Sunday, December 11th

Data to be presented in poster at ASH Annual Meeting


SAN DIEGO and TORONTO, Dec. 07, 2022 (GLOBE NEWSWIRE) -- Aptose Biosciences Inc. (“Aptose” or the “Company”) (NASDAQ: APTO, TSX: APS), a clinical-stage precision oncology company developing highly differentiated oral kinase inhibitors to treat hematologic malignancies, today announced that the company’s management team will provide a corporate update on Sunday, December 11, 2022, at 10:00 AM EST / 9:00 CST, in conjunction with poster presentations at the 64th American Society of Hematology (ASH) Annual Meeting and Exposition, being held in New Orleans, LA. The webcast event will include a comprehensive review of current clinical data for Aptose’s lead compound tuspetinib, formerly HM43239, a myeloid kinase inhibitor, as well as an update on luxeptinib, Aptose’s oral, dual lymphoid and myeloid kinase inhibitor.

Tuspetinib, administered as a once-daily oral tablet, is a precision targeted kinase inhibitor designed to suppress a select handful of kinases known to drive the proliferation of acute myeloid leukemia (AML) but avoids other kinases that can compromise safety. The data review will highlight results from the recently completed Phase 1/2 dose escalation clinical trial of tuspetinib.
