BIND Therapeutics and Synergy Pharmaceuticals Announce Collaboration to Develop ACCURINS® with Proprietary Uroguanylin Analogs for Targeting Gastrointestinal Receptors on Tumors

CAMBRIDGE, Mass. & NEW YORK--(BUSINESS WIRE)-- BIND Therapeutics, Inc. (NASDAQ: BIND), a clinical-stage nanomedicine company developing targeted and programmable therapeutics called ACCURINS®, and Synergy Pharmaceuticals Inc. (NASDAQ: SGYP), a biopharmaceutical company pioneering the development of uroguanylin analogs as potential new treatments for functional gastrointestinal (GI) disorders and inflammatory bowel disease (IBD), today announced they have entered into a research collaboration to engineer ACCURINS® incorporating Synergy's proprietary uroguanylin analogs to explore the potential targeting of guanylate cyclase-C (GC-C) receptors expressed on tumors, specifically GI malignancies. Upon achievement of proof-of-concept, the companies anticipate expanding the collaboration to enhance the potential effect of uroguanylin-based ACCURINS® by incorporating therapeutic payloads.

"This collaboration represents another important advance as we develop ACCURINS® with the potential to target a broad range of cells with novel therapeutic payloads," said Jonathan Yingling, Ph.D., chief scientific officer, BIND Therapeutics. "The versatility of our platform is demonstrated by our wide range of collaborations and the ability to leverage our technology platform in a wide variety of applications. We believe the complementary technologies of Synergy and BIND have the potential to generate novel uroguanylin-based therapies that could have a profound impact on the treatment of diseases."

Uroguanylin is a naturally occurring GI peptide and activator of the intestinal GC-C receptor, which is a known target for stimulating a variety of physiological responses. Plecanatide, Synergy's lead uroguanylin analog for functional GI disorders, successfully completed phase 3 clinical trials for chronic idiopathic constipation (CIC) in 2015, and the Company recently filed a new drug application (NDA) for plecanatide to treat CIC. Synergy also recently announced positive data on its second uroguanylin analog, dolcanatide, in a phase 1b proof-of-concept study in ulcerative colitis patients.

"We are pleased to collaborate with BIND Therapeutics on this project, which we believe can broaden the potential therapeutic applications of our proprietary uroguanylin-based platform," said Kunwar Shailubhai, Ph.D., M.B.A., chief scientific officer and executive vice president of Synergy Pharmaceuticals. "BIND's ACCURIN technology has been shown to target diseased tissues with a wide variety of therapeutic payloads. We have separately presented data showing that uroguanylin analogs specifically bind to different types of colorectal polyps and tumor in mice. Together, we believe that we can create uroguanylin-based ACCURINS® that have the potential to provide new treatment options in GI cancer."

This early research collaboration is not expected to have a material financial impact on Synergy Pharmaceuticals or BIND Therapeutics.

About ACCURINS®

ACCURINS®, a new class of targeted therapeutics developed using BIND's Medicinal Nanoengineering® platform, are nanoparticles engineered to have a profound impact on the treatment of disease. The elegant and novel design of ACCURINS® allow for prolonged circulation, controlled and tunable release and selective targeting of a therapeutic payload to diseased tissue or cells while avoiding immune surveillance detection and systemic toxicities.

ACCURINS® can be engineered for multiple therapeutic applications and have the potential to integrate numerous payloads, including highly potent drugs with mechanism-based toxicities that limit therapeutic benefit, DNA, RNA, proteins and immunotherapy agents. This attribute enables ACCURINS® to target multiple diseases, including cancer, inflammatory, vascular, and infectious disease.

About BIND Therapeutics

BIND Therapeutics is a clinical-stage nanomedicine company developing a pipeline of ACCURINS®, its novel targeted therapeutics designed to increase the concentration and duration of therapeutic payloads at disease sites while reducing exposure to healthy tissue. BIND is leveraging its Medicinal Nanoengineering® platform to develop a pipeline of ACCURINS® targeting hematological and solid tumors and has a number of strategic collaborations with biopharmaceutical companies to develop ACCURINS® in areas of high unmet need. BIND's lead drug candidate, BIND-014, is a prostate-specific membrane antigen (PSMA) -targeted ACCURIN that contains docetaxel, a clinically-validated and widely-used cancer chemotherapy drug. BIND is currently evaluating BIND-014 in the phase 2 iNSITE 1 trial for non-small cell lung cancer, or NSCLC, with squamous histology. In addition, BIND is enrolling patients in the iNSITE 2 clinical trial with BIND-014 for advanced cancers of the cervix and head and neck. BIND is advancing BIND-510, its second PSMA-targeted ACCURIN drug candidate containing vincristine through important preclinical gating studies to potentially position it for an Investigational New Drug (IND) application filing with the U.S. Food and Drug Administration. BIND is also developing ACCURINS® designed to inhibit PLK1 and KSP, both of which BIND believes are promising anti-mitotic targets that have been limited in the clinic due to systemic toxicity at or below their therapeutic doses.

BIND has announced ongoing collaborations with Pfizer Inc., AstraZeneca AB, F. Hoffmann-La Roche Ltd., Merck & Co., or Merck (known as Merck Sharp & Dohme outside the United States and Canada), Macrophage Therapeutics (a subsidiary of Navidea Biopharmaceuticals) and Synergy Pharmaceuticals to develop ACCURINS® based on their proprietary therapeutic payloads and/or targeting ligands. BIND's collaboration with AstraZeneca has resulted in the Aurora B Kinase inhibitor ACCURIN AZD2811, which became the second ACCURIN candidate to enter clinical development. BIND's collaboration with Pfizer has resulted in the selection of an ACCURIN candidate that is entering IND-enabling studies.

About Synergy Pharmaceuticals Inc.

Synergy Pharmaceuticals (NASDAQ: SGYP) is a biopharmaceutical company focused on the development and commercialization of novel GI therapies. Synergy's proprietary GI platform is based on uroguanylin and includes two lead product candidates - plecanatide and dolcanatide. Plecanatide is Synergy's first uroguanylin analog currently being developed for two functional GI disorders, CIC and irritable bowel syndrome with constipation (IBS-C). Plecanatide is a 16-amino acid peptide that is structurally identical to uroguanylin with the exception of a single amino acid change. Taken as a tablet once-a-day, plecanatide is designed to mimic the function of uroguanylin by working locally in the upper GI tract to activate and regulate fluid movement required for healthy bowel function. In 2015, Synergy announced positive phase 3 data in two CIC clinical trials and on January 29, 2016 the company filed a NDA with plecanatide for CIC. Synergy is continuing to progress two phase 3 clinical trials with plecanatide for IBS-C. The company expects top-line results from the first phase 3 IBS-C trial in 1H 2016 and results from the second phase 3 IBS-C trial are expected in 2H 2016. Synergy intends to file its second NDA with plecanatide for IBS-C by year-end 2016. Dolcanatide is Synergy's second uroguanylin analog currently being explored for ulcerative colitis. Dolcanatide is designed to be an analog of uroguanylin with enhanced resistance to standard digestive breakdown by proteases in the intestine. In January 2016, Synergy announced positive phase 1b data with dolcanatide in patients with mild-to-moderate ulcerative colitis and the company is presently evaluating plans for further clinical development in IBD.
