Bio-Path Holdings Presents Interim Data from Phase 2 Study Evaluating Prexigebersen as a Treatment for Acute Myeloid Leukemia at the 60th Annual American Society of Hematology Annual Meeting

HOUSTON, Dec. 03, 2018 (GLOBE NEWSWIRE) — Bio-Path Holdings, Inc., (NASDAQ: BPTH), a biotechnology company leveraging its proprietary DNAbilize® antisense RNAi nanoparticle technology to develop a portfolio of targeted nucleic acid cancer drugs, today announced that previously announced interim data from the Company’s Phase 2 study evaluating prexigebersen as a treatment for acute myeloid leukemia (AML) were presented in a poster at the 2018 American Society of Hematology (ASH) Annual Meeting and Exposition, taking place from December 1-4, 2018 in San Diego, CA.

Maro Ohanian, M.D., Assistant Professor of the Department of Leukemia at The University of Texas MD Anderson Cancer Center, presented the poster titled, “Interim Safety and Efficacy of Lower Intensity Induction Therapy with Intravenous Prexigebersen (BP1001) in Patients with Untreated Acute Myeloid Leukemia (AML).” The poster reviewed interim data from the Company’s open-label Phase 2 study evaluating the efficacy and safety of prexigebersen in conjunction with low-dose cytarabine (LDAC), a therapeutic regimen well established in treatment of AML patients who cannot or elect not to be treated with more intensive chemotherapy.  The primary objective of the study is to determine whether the combination of prexigebersen and LDAC provides greater efficacy than what would be expected with LDAC alone in this de novo patient population. 

Prexigebersen was safely administered to patients with untreated AML, who were considered unsuitable for standard chemotherapy. Of the 17 evaluable patients, there were four patients (24%) who achieved complete responses and four patients with stable disease including one patient who achieved a morphologic leukemia free state and two patients who had significantly reduced bone marrow blasts.  In total, 47% of the evaluable patients showed some form of response, including stable disease, to the combination treatment. Efficacy data are encouraging in this challenging population in which the majority of patients had secondary AML or adverse-risk AML, and compares favorably to the reported CR (complete remission), CRp (complete remission with incomplete platelet recovery), and CRi (complete remission with incomplete hematologic recovery) rate with LDAC alone of 7-13%1

“We are excited to be presenting these important data at ASH before an audience of world-leading scientists and oncologists, as they demonstrate the potential for the combination of prexigerbesen and LDAC to safely and effectively treat these de novo AML patients, including doubling the complete response to treatment compared to LDAC treatment alone,” noted Peter H. Nielsen, chief executive officer of Bio-Path. “We look forward to presenting final data from this study as we expect they will provide even better results for these patients suffering with AML.”
