Aptose Biosciences (NASDAQ: APTO, TSX: APS) received a positive decision from the Nasdaq Hearings Panel, granting an extension until March 31, 2025 to meet continued listing requirements. The company must demonstrate compliance with two key criteria: maintaining minimum shareholders' equity of $2.5 million and achieving a minimum bid price of $1.00 for at least 10 consecutive business days.
Following the November 21 hearing, Aptose has made significant progress, including closing an $8 million public offering, securing a clinical development agreement with the National Cancer Institute for tuspetinib development in AML and MDS, and presenting clinical data at ASH supporting tuspetinib triplet therapy for newly diagnosed AML patients.
Aptose Biosciences (NASDAQ: APTO, TSX: APS) announced the publication of preclinical data for tuspetinib (TUS) in Cancer Research Communications. The study demonstrates TUS's effectiveness as an oral kinase inhibitor for treating acute myeloid leukemia (AML). Key findings show that TUS inhibits specific oncogenic signaling kinases in AML, effectively kills AML cell lines, and shows enhanced activity when combined with venetoclax (VEN) or azacitidine (AZA).
The research revealed TUS's favorable pharmacokinetic profile supporting once-daily dosing and its ability to prolong survival in multiple AML models. Aptose is currently enrolling newly diagnosed AML patients in a Phase 1/2 clinical study for the TUS+VEN+AZA triplet combination therapy.
Aptose Biosciences presented clinical data for tuspetinib (TUS) at the 66th ASH Annual Meeting, highlighting its potential in treating acute myeloid leukemia (AML). The data supports the advancement of TUS+VEN+AZA triplet therapy for newly diagnosed AML patients.
Key findings show that TUS as a single agent achieved 60% and 42% CR/CRh rates with 80mg in FLT3 mutated and all-comer VEN-naïve AML respectively. In combination therapy, TUS+VEN showed 40% ORR with 80mg TUS + 400mg VEN in FLT3 mutated patients, with 83% of these patients having failed prior-VEN treatment.
The drug demonstrated favorable safety profiles both as monotherapy and in combination, with no dose-limiting toxicities through 160mg daily dosing, no drug-related discontinuations, and no deaths.
Aptose Biosciences (NASDAQ: APTO, TSX: APS) has entered into a Cooperative Research and Development Agreement (CRADA) with the National Cancer Institute (NCI) to develop tuspetinib for AML and MDS treatment.
