AB Science announces the first presentation of preclinical results for
compound AB8939 in the 61st ASH Annual Meeting online program
AB Science SA (NYSE Euronext - FR0010557264 - AB) announces today the first presentation of preclinical study results showing that compound AB8939 is capable of counteracting resistance to oncology treatments.
Entitled, ‘Anticancer Activity of a Highly Potent Small Molecule Tubulin Polymerization Inhibitor, AB8939’, the full abstract and presentation schedule are accessible online from the conference website: https://ash.confex.com/ash/2019/webprogram/Paper122540.html.
This presentation will be delivered at the conference by Pr Olivier Hermine, MD, PhD. Olivier Hermine is Professor of Hematology at Paris V-René Descartes University, Chief of Adult Hematology at Hospital Necker (Paris), member of the French Académie des Sciences and author of 365 international publications.
Professor Olivier Hermine commented: “AB8939 seems particularly well-suited for treatment of relapsed/refractory AML (acute myeloid leukemia), being P-glycoprotein-insensitive and having demonstrated potent activity in relevant chemoresistant AML models. AML is a serious life-threatening condition and the most common cause of leukemia-related mortality. Chemoresistance is a major obstacle to frontline AML drugs with no standard regimen to date for the treatment of relapsed/refractory patients”.
As reported in the above referenced abstract, a series of in vitro preclinical studies provide proof-of-concept that AB8939 has broad applicability as a potent anticancer drug, particularly in tumors of hematopoietic and lymphoid tissues, including acute myeloid leukemia (AML). Notably, AB8939 is able to circumvent two major resistance mechanisms, namely multidrug resistance P-glycoprotein (Pgp) and myeloperoxidase (MPO) mediated resistance, thereby conferring an important advantage over traditional tubulin inhibitors.
These data show that AB8939 is a highly potent Pgp-independent, next-generation microtubule-destabilizer drug for cancer therapy, in particular, difficult to treat hematopoietic tumors such as relapsed/refractory AML. A first in human, phase 1 trial evaluating AB8939 in AML patients unfit to receive intensive chemotherapy in second and third-line will be initiated in 2020. The European Medicine Agency (EMA) has validated the clinical development program for AB8939 in AML through a Scientific Advice procedure.
AB8939 is a novel microtubule destabilizing agent that is differentiated from other drugs of this class primarily by its inability to be transported by P-glycoprotein, thereby having potential to overcome Pgp-dependent multidrug resistance in cancer patients.
