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 chronic lymphocytic leukemia (CLL), non-Hodgkin’s lymphoma (NHL), acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), 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:

CG-806: Phase 1a/b

CG-806 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.

CG-806: Phase 1a/b

CG-806 is in a Phase 1a/b clinical trial for the treatment of patients with relapsed or refractory AML.

APTO-253: Phase 1b

APTO-253 is in a Phase 1b clinical trial for the treatment of patients with relapsed or refractory AML and high risk MDS.
