Bio-Path Holdings Presents Data from Ongoing Phase 2 Combination Study of Prexigebersen for Treatment of Acute Myeloid Leukemia at European Hematology Association Congress

Encore Presentation Highlights Positive Results from Interim Analysis Demonstrating Significant Clinical Improvement and Tolerable Safety Profile for Prexigebersen Combination in High-Risk Patients

HOUSTON, June 14, 2024 (GLOBE NEWSWIRE) -- Bio-Path Holdings, Inc., (NASDAQ:BPTH), a biotechnology company leveraging its proprietary DNAbilize® liposomal delivery and antisense technology to develop a portfolio of targeted nucleic acid cancer drugs, presented interim results from the Company’s Phase 2 study of prexigebersen (BP1001) in combination with decitabine and venetoclax for the treatment of acute myeloid leukemia (AML) in a poster presentation at 2024 European Hematology Association (EHA) Congress, on June 14, 2024 in Madrid, Spain.

Jorge Cortes, M.D., Director of the Georgia Cancer Center, presented data showing prexigebersen continues to be well-tolerated and has now demonstrated compelling efficacy results in two reporting cohorts including evaluable newly diagnosed AML patients and evaluable refractory/relapsed AML patients, both of which exceeded outcomes with frontline therapy.

“It was a pleasure to present these compelling data to an audience of European oncologists who treat AML patients and understand the continued great need for new therapeutic options,” said Peter Nielsen, Chief Executive Officer of Bio-Path. “Given that our study is being conducted in the U.S., this encore presentation is an important step towards educating global oncology leaders on the benefits of prexigebersen and its potential to be another tool in their fight against AML.”

Data Highlights

In Cohort 1, 31 newly diagnosed patients were enrolled; 20 evaluable patients (9 male: 45%) with a median age of 75 years (range, 69 - 84), treated with at least one cycle of prexigebersen, decitabine and venetoclax, had adverse-risk (n=12, 2017 ELN guidelines) or secondary AML (sAML; n=7) evolved from myelodysplastic syndromes (n=4), chronic myelomonocytic leukemia (n=1) or treatment-related AML (n=2). Fifteen patients (75% of evaluable; 54% of enrolled) achieved complete remission (CR), CRh (CR with partial recovery of peripheral blood counts), or CRi (CR with incomplete hematologic recovery); two patients achieved partial remission (PR) and two patients achieved stable disease (SD).

In Cohort 2, 38 relapsed/refractory patients were enrolled; 23 evaluable patients (13 male: 57%) with a median age of 63 years (range, 24 - 89), treated with at least one cycle of prexigebersen, decitabine and venetoclax, had adverse-risk (n=13) or sAML (n=5). Twelve patients (55% of evaluable; 32% of enrolled) achieved CR/CRi/CRh; one patient achieved PR, eight patients achieved SD and one patient had treatment failure.

Among the evaluable patients of both cohorts, adverse events were consistent with those expected with decitabine and venetoclax and/or AML, including fatigue (72%), anemia (60%) and neutropenia (49%), while the most frequent severe adverse events were febrile neutropenia (26%) and sepsis (5%). Given these promising interim results, Bio-Path expects to continue enrollment of up to 98 and 54 evaluable patients for Cohorts 1 and 2, respectively.
