Aptose Biosciences announced an equity distribution agreement with JonesTrading to sell common shares through at-the-market offerings on NASDAQ. The company can issue shares worth up to US$50 million as outlined in a prospectus filed with the SEC. Aptose focuses on developing oral kinase inhibitors for hematologic malignancies, with two candidates, tuspetinib and luxeptinib, currently in clinical trials. This strategic move may enhance capital for ongoing research and operations.
Aptose Biosciences has released a clinical update on tuspetinib, a myeloid kinase inhibitor, showing promising results in a Phase 1/2 trial for patients with relapsed/refractory acute myeloid leukemia (AML). As of October 6, 2022, 60 patients have been treated with doses ranging from 20 mg to 200 mg, achieving multiple complete remissions (CR). Tuspetinib's favorable safety profile and high response rates suggest potential for combination therapies. Additionally, luxeptinib continues to show efficacy in hematologic malignancies, with ongoing trials for modified formulations.
Aptose Biosciences Inc. (NASDAQ: APTO, TSX: APS) will present key updates at the ASH Annual Meeting on December 11, 2022. The webcast at 10:00 AM EST will cover clinical data for tuspetinib and luxeptinib. Tuspetinib, a myeloid kinase inhibitor, is in a Phase 1/2 trial for acute myeloid leukemia (AML). Key poster presentations include data on the Phase 1/2 dose escalation study of tuspetinib and luxeptinib. Additional data will be shared at the event, providing insights into the company’s advancements in oncology.
Aptose Biosciences has initiated dosing for the first patient in a continuous dosing regimen of the G3 formulation of luxeptinib for relapsed or refractory acute myeloid leukemia (AML). This Phase 1a/b clinical trial seeks to enhance drug bioavailability significantly, as the new formulation is expected to provide similar plasma exposure to the higher dose of the original formulation while reducing potential toxicity. The company is optimistic about the G3's efficacy and hopes it will yield better clinical responses in difficult-to-treat AML patients.
