Bio-Path Holdings Provides Clinical Update and 2018 Business Outlook

HOUSTON, Dec. 29, 2017 -- 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 provided an update from several clinical programs and provided a 2018 business overview.

“We are very excited about the potential for Bio-Path as we enter 2018. The year ahead is expected to be highlighted by a variety of value-creating milestones across a number of important clinical development programs aimed at further validating our DNAbilize platform as a potential treatment for a variety of oncology indications,” stated Peter H. Nielsen, chief executive officer of Bio-Path Holdings. “We continue to advance our unique platform technology to address a number of cancers that remain unresponsive to current treatment paradigms.”

“We are very encouraged about the potential for our DNAbilize technology, which is supported by compelling earlier data that show prexigebersen to be safe and efficacious against a wide range of cancer indications and are hopeful that these positive data will be replicated in our ongoing late-stage clinical trials,” continued Mr. Nielsen. 

Phase 2 Study of Prexigebersen in De Novo AML Patients

Bio-Path is conducting a Phase 2 clinical trial of its lead drug candidate, prexigebersen, in combination with frontline therapy low dose cytarabine (LDAC) in de novo acute myeloid leukemia (AML) patients who are ineligible or unwilling to undergo intensive induction therapy.  The single arm trial is designed for up to 54 evaluable patients with an interim analysis performed after 19 patients. 

To-date in this study, over 50 potential patients have been pre-screened, 26 patients have been screened, 23 patients have been enrolled and 17 patients have been deemed evaluable with 6 additional patients currently undergoing treatment. Bio-Path expects the 19 patient pre-specified analysis to be completed in early 2018, at which time the assessment of these patients will be addressed by Bio-Path.

Plans for a pivotal trial will be discussed with the FDA if these results exceed expectations for current standard of care therapy.

Phase 2a Study of Prexigebersen in Accelerated and Blast Phase CML Patients

Bio-Path today announces the initiation of its Phase 2a clinical study of prexigebersen for the treatment of chronic myeloid leukemia (CML). The trial is being conducted at The University of Texas MD Anderson Cancer Center as a potential salvage therapy for accelerated and blast phase CML patients. Two cohorts of three evaluable patients each will be enrolled to evaluate two doses (60 mg/m2 and 90 mg/m2) of prexigebersen in combination with the front-line treatment dasatinib. 

Phase 1 Study of BP1002 in Refractory or Relapsed Lymphoma Patients

In 2018, Bio-Path intends to initiate a Phase 1 clinical trial of BP1002, an antisense RNAi nanoparticle targeting the Bcl-2 protein, in refractory or relapsed lymphoma patients. The clinical trial would evaluate the safety of BP1002 in several dose escalating cohorts to determine a maximum tolerated dose and/or optimal biologically active dose.
