Tuspetinib is being developed for frontline AML therapy as part of the TUS+VEN+AZA triplet for newly diagnosed AML patients ineligible to receive intensive chemotherapy. Tuspetinib, a convenient once daily oral agent that potently targets SYK, FLT3, mutated KIT, JAK1/2, and RSK2 kinases, avoids many typical toxicity concerns observed with other agents and has the potential to treat the larger AML populations, not just narrow subpopulations. In the recently conducted Phase 1/2 APTIVATE trial in a very ill and heavily pre-treated relapsed or refractory (R/R) AML population, tuspetinib as a single agent (TUS) and in combination with venetoclax (TUS+VEN) safely achieved broad activity across various difficult-to-treat AML subpopulations. This included patients with prior-VEN, prior-FLT3 inhibitor (FLT3i) and prior-hematopoietic stem cell transplantation (HSCT) therapies, those with highly adverse genetics - including mutations in TP53 and RAS genes, and those with mutated or unmutated (wildtype) FLT3 genes.
“Initiation of the trial is a key milestone for Aptose. AML treatment has rapidly shifted to combination therapies, and we are pleased to include tuspetinib as part of TUS+VEN+AZA triplet combination therapy in patients with newly-diagnosed AML – representing a new patient population for TUS,” said William G. Rice, Chairman, President and Chief Executive Officer. “We thank our investigators for their enthusiasm and our clinical team for activating the TUSCANY triplet study. As one of our investigators noted, if TUS brings added efficacy to frontline treatment of a broad array of AML patients without the added toxicities that are plaguing some other agents, we may have a game changer in TUS.”
TUSCANY: TUS+VEN+AZA Triplet Phase 1/2 StudyThe triplet Phase 1/2 study is designed to test various doses and schedules of TUS in combination with standard of care dosing of azacitidine and venetoclax. TUS will be administered in 28-day cycles, beginning with 40mg, with dose escalations planned after safety review of each dose level. A planned 12 sites in the US will enroll in the TUSCANY trial with anticipated enrollment of 18-24 patients by mid-late 2025.
More information on the TUSCANY Phase 1/2 study can be found on www.clinicaltrials.gov (here).
About AptoseAptose Biosciences is a clinical-stage biotechnology company committed to developing precision medicines addressing unmet medical needs in oncology, with an initial focus on hematology. The Company's small molecule cancer therapeutics pipeline includes products designed to provide single agent efficacy and to enhance the efficacy of other anti-cancer therapies and regimens without overlapping toxicities. The Company has two clinical-stage oral kinase inhibitors under development for hematologic malignancies: tuspetinib (TUS), an oral, kinase inhibitor that has demonstrated activity as a monotherapy and in combination therapy in patients with relapsed or refractory acute myeloid leukemia (AML) and is being developed as a frontline triplet therapy in newly diagnosed AML; and luxeptinib (CG-806), an oral, dual lymphoid and myeloid kinase inhibitor in Phase 1 a/b stage development for the treatment of patients with relapsed or refractory hematologic malignancies.
