Novel thiazolidinedione derivatives of the potent antioxidant, alpha-lipoic (thioctic, 1,2-dithiolane) acid, were prepared. The prototype N-(2-[4-[2,4-dioxo(1,3-thiazolidin-5-yl)methyl]phenoxy]ethyl)-5-(1,2-dithiolan-3-yl)- N-methylpentanamide (designated BP-1003), and dithioester derivatives thereof were shown to be potent activators of peroxisome proliferator-activated receptor gamma (PPARgamma) (EC(50) range 15-101 nM) and modest activators of PPARalpha (EC(50) 5 microM). Both the relatively hydrophobic dithiolane prototype, BP-1003, and its water-soluble dithioglycinate derivative, BP-1017, were shown to inhibit the proliferation of human keratinocytes and suppress the production of interleukin-2 by human peripheral lymphocytes to a greater extent than the antidiabetic thiazolidinedione, rosiglitazone. Both oral and topical administration of BP-1017 showed significant antiinflammatory effects in the oxazolone-sensitized mouse model of allergic contact dermatitis (ACD). These findings suggest that water-soluble lipoic acid-based thiazolidinediones may be efficacious as oral and topical agents for treating inflammatory skin conditions such as contact dermatitis, atopic dermatitis, and psoriasis.

BP1003 Decreases STAT3 Expression and Its Pro-Tumorigenic Functions in Solid Tumors and the Tumor Microenvironment

Article

Overexpression and aberrant activation of signal transducer and activator of transcription 3 (STAT3) contribute to tumorigenesis, drug resistance, and tumor-immune evasion, making it a potential cancer therapeutic target. BP1003 is a neutral liposome incorporated with a nuclease-resistant P-ethoxy antisense oligodeoxynucleotide (ASO) targeting the STAT3 mRNA. Its unique design enhances BP1003 stability, cellular uptake, and target affinity. BP1003 efficiently reduces STAT3 expression and enhances the sensitivity of breast cancer cells (HER2+, triple negative) and ovarian cancer cells (late stage, invasive ovarian cancer) to paclitaxel and 5-fluorouracil (5-FU) in both 2D and 3D cell cultures. Similarly, ex vivo and in vivo patient-derived models of pancreatic ductal adenocarcinoma (PDAC) show reduced tissue viability and tumor volume with BP1003 and gemcitabine combination treatments. In addition to directly affecting tumor cells, BP1003 can modulate the tumor microenvironment. Unlike M1 differentiation, monocyte differentiation into anti-inflammatory M2 macrophages is suppressed by BP1003, indicating its potential contribution to immunotherapy. The broad anti-tumor effect of BP1003 in numerous preclinical solid tumor models, such as breast, ovarian, and pancreatic cancer models shown in this work, makes it a promising cancer therapeutic.

Bio-Path Holdings Initiates Development of Therapeutic Program for Treatment of Obesity

HOUSTON, Oct. 08, 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, today announced the initiation of a therapeutic program to develop BP1001-A for the treatment of obesity and related metabolic diseases. This program marks the first application of DNAbilize technology for development of a non-cancer application, which highlights the broad therapeutic potential of this technology. The Company also reported completion of enrollment in the third dosing cohort of its ongoing Phase 1/1b clinical trial evaluating BP1002 for the treatment of refractory/relapsed acute myeloid leukemia (AML) patients, including venetoclax-resistant patients. The cohort enrolled more quickly than projected, which underscores the ongoing need for new treatment options for these relapsed/refractory patients. “Initiating a DNAbilize development program for the treatment of obesity is an exciting expansion opportunity with the potential to treat a growing epidemic. Developing BP1001-A for the treatment of obesity should have a high probability of success as its mechanism of action has the potential to treat insulin resistance, which is the underpinning of obesity, Type 2 diabetes and other related diseases,” said Peter H. Nielsen, President and Chief Executive Officer of Bio-Path. “We expect to initiate Investigational New Drug (IND)-enabling testing of BP1001-A in the fourth quarter of 2024.” “In addition, we are pleased to report enrollment for the third dosing cohort of the Phase 1/1b clinical trial of BP1002 in refractory/relapsed AML patients has completed faster than projected. AML patients who had relapsed from frontline venetoclax-based treatment and are refractory to salvage therapy face dire survival prospects and we believe that BP1002 therapy can help these patients,” concluded Mr. Nielsen. BP1001-A for Treatment of Obesity – The disease pathology leading to obesity suggests that BP1001-A, which suppresses the adaptor protein Grb2, has the potential to treat insulin resistance, a major contributor to obesity, Type 2 diabetes and other related metabolic diseases. Bio-Path expects downregulating Grb2 expression with BP1001-A will enhance insulin sensitivity. The Company expects to begin preclinical studies to confirm these assumptions in the fourth quarter of 2024. These studies are expected to provide crucial insights into the mechanism and efficacy of BP1001-A in enhancing insulin sensitivity and reveal its therapeutic potential for obesity and Type 2 diabetes. Following successful preclinical studies, Bio-Path anticipates that a Phase 1 clinical trial would follow. Completion of Enrollment for Third Dosing Cohort of Phase 1/1b Clinical Trial of BP1002 in Refractory/Relapsed AML Patients - After the U.S. Food and Drug Administration (FDA) completed its review of data from the first two dosing cohorts in the Phase 1/1b clinical trial in refractory/relapsed AML patients, Bio-Path initiated enrollment for the third, higher-dosing cohort of 60 mg/m2. Enrollment was completed faster than projected within six weeks, which underscores the continuing need for new treatment options. By targeting the key protein involved in the venetoclax treatment at the mRNA level, BP1002 may overcome and prevent some of the mechanisms of resistance that affect venetoclax treatment.

Bio-Path Holdings Announces Publication in Biomedicines

Manuscript Highlights Therapeutic Potential of BP1003 in Variety of Cancers Marks Company’s Twenty-Second Peer-Reviewed Publication in Support of its DNAbilize® Technology HOUSTON, Sept. 16, 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, today announced a publication highlighting the therapeutic potential of BP1003 in a variety of cancer types in the peer-reviewed journal, Biomedicines. The article, titled “BP1003 Decreases STAT3 Expression and Its Pro-Tumorigenic Functions in Solid Tumors and the Tumor Microenvironment,” describes the broad anti-tumor effect of BP1003 in numerous preclinical solid tumor models including breast, ovarian, and pancreatic cancer. BP1003 is a neutral liposome incorporated with a nuclease resistant P-ethoxy antisense oligodeoxynucleotide targeting the STAT3 mRNA and its unique design enhances stability, cellular uptake, and target affinity. The article was authored by Maria Gagliardi, Ph.D., Senior Research Scientist, Michael Roberts, Director of Manufacturing Planning & Engineering, and Ana Tari Ashizawa, Ph.D., Senior Vice President of Research, Development and Clinical Design at Bio-Path Holdings. The article’s co-authors included investigators from Thomas Jefferson University and University of Texas MD Anderson Cancer Center. “Overexpression and aberrant activation of STAT3 contributes to tumorigenesis, drug resistance, and tumor-immune evasion, making it a probable cancer therapeutic target. Consequently, we believe BP1003 has the potential to enhance the efficacy of current standard of care chemotherapies in a broad range of difficult to treat cancers,” said Dr. Tari Ashizawa.
