HOUSTON -- (BUSINESS WIRE) -- Bio-Path Holdings, Inc., (OTCQX: BPTH) (“Bio-Path”), a biotechnology company developing a liposomal delivery technology for nucleic acid cancer drugs, announced that Dr. Jorge Cortes, deputy chair and professor of medicine in the Department of Leukemia at The University of Texas MD Anderson Cancer Center, presented Phase I data from Bio-Path’s clinical trial evaluating its lead product candidate, Liposomal Grb-2 (BP-100-1.01), in hematological cancers at the 55th Annual Meeting of the American Society of Hematology (ASH) in New Orleans.
The study titled “Safety, Pharmacokinetics, and Efficacy Of BP-100-1.01 (Liposomal Grb-2 Antisense Oligonucleotide) In Patients With Refractory Or Relapsed Acute Myeloid Leukemia (AML), Philadelphia Chromosome Positive Chronic Myelogenous Leukemia (CML), Acute Lymphoblastic Leukemia (ALL), and Myelodysplastic Syndrome (MDS)” included the first five cohorts of the study. The sixth cohort of the study is ongoing, and Bio-Path expects to have enrollment completed in the first quarter of 2014.
The clinical trial was a standard dose-finding study. The starting dose was 5 mg/m2 twice weekly intravenously (IV) over two to three hours for 28 days and proceeded through doses of 10, 20, 40, and 60 mg/m2. A total of 28 patients who had failed other therapies were included in the study (19 AML, 4 MDS and 5 CML), and 18 patients were evaluable. Ten patients failed to complete the full 28-day treatment cycle due to disease progression with no toxicity.
Data from the Phase I trial demonstrated:
Disease Stabilization in MDS and AML
Experience in CML-Blast Phase
Inhibition of Target Grb-2 Protein
About Bio-Path’s Delivery Technology
Bio-Path’s drug delivery technology involves microscopic-sized liposome particles that distribute nucleic acid drugs systemically and safely throughout the human body, via simple intravenous infusion. The delivery technology is applied to single stranded (antisense) nucleic acid compounds with the potential to revolutionize the treatment of cancer and other diseases where drugable targets of disease are well characterized. The Company is currently focused on developing liposomal antisense drug candidates. Bio-Path also anticipates developing liposome tumor targeting technology, representing next-generation enhancements to the Company’s core liposome delivery technology.
About Growth Receptor Bound protein-2 (Grb-2)
The adaptor protein Growth Receptor Bound protein-2 (Grb-2) is essential to cancer cell signaling because it is utilized by oncogenic tyrosine kinases to induce cancer progression. Suppressing the function or expression of Grb-2 should interrupt its vital signaling function and have a therapeutic application in cancer. BP-100-1.01 is a neutral-charge, liposome-incorporated antisense drug substance designed to inhibit Grb-2 expression.
About Bio-Path Holdings, Inc.
Bio-Path is a biotechnology company focused on developing therapeutic products utilizing its proprietary liposomal delivery technology designed to systemically distribute nucleic acid drugs throughout the human body with a simple intravenous transfusion. Bio-Path’s lead product candidate, Liposomal Grb-2, is in a Phase I study for blood cancers and in preclinical studies for triple negative and inflammatory breast cancers. Bio-Path’s second drug candidate, also a liposomal antisense drug, is ready for the clinic where it will be evaluated in lymphoma and solid tumors.
