Precision Oncology for Therapies of Tomorrow

Aptose Biosciences is a science-driven clinical-stage biotechnology company developing first-in-class targeted agents to address the unmet clinical need in acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), chronic lymphocytic leukemia (CLL), non-Hodgkin’s lymphoma (NHL), and other hematologic malignancies.

Broad Applicability Across the Hematology Spectrum

Our drug candidates have been designed to provide safe single agent efficacy in multiple adjacent indications, as well as enhance the efficacy of other anti-cancer therapies and regimens without overlapping toxicities.

Our Clinical Trials in Hematologic Malignancies

Currently, we have three ongoing clinical trials with our investigational drug candidates:

HM43239: Phase 1/2

HM43239 is in a Phase 1/2 clinical trial for the treatment of patients with relapsed or refractory AML

Luxeptinib: Phase 1a/b

Luxeptinib is in a Phase 1a/b clinical trial for the treatment of patients with B-cell malignancies, including CLL and NHL, who have failed or are intolerant to the standard treatments available.

Luxeptinib: Phase 1a/b

Luxeptinib is in a Phase 1a/b clinical trial for the treatment of patients with relapsed or refractory AML and high risk MDS.
