BEDMINSTER, N.J., June 20, 2016 (GLOBE NEWSWIRE) -- Matinas BioPharma Holdings, Inc. (OTCQB:MTNB), a clinical-stage biopharmaceutical company focused on identifying and developing safe and effective broad spectrum therapeutics for the treatment of serious and life-threatening infections, today presented preclinical data on its investigational drug, MAT2501 (orally-administered encochleated amikacin) for chronic and acute bacterial infections, including non-tuberculous mycobacteria (NTM) and multi-drug resistant gram-negative bacterial infections, at the American Society for Microbiology’s Interscience Conference of Antimicrobial Agents and Chemotherapy (ASM Microbe/ICAAC 2016) scientific meeting being held June 16th – 20th in Boston, MA.
The abstract entitled “Oral Encochleated Amikacin Demonstrates Reduced Toxicity Compared to Intravenous Amikacin in Rats” was presented today in a poster session focused on antimicrobial resistance and the approaches on how to fight against it. MAT2501 is a broad spectrum aminoglycoside antibiotic agent delivered in the Company’s proprietary lipid-crystal nano-particle cochleate formulation technology.
"This study of our orally administered cochleate technology, in comparison to I.V. administration of amikacin, continues to increase our belief in our potential to deliver this powerful anti-infective at a lower toxicity and offer a new treatment option for immunocompromised patients with chronic and resistant gram-negative infections," said Roelof Rongen, Chief Executive Officer. "We look forward to continue exploring the benefit and potential of our formulation of amikacin utilizing our proprietary lipid-crystal nano-particle cochleate technology."
In the study, rats were administered 50 or 200 mg/kg/day doses of oral MAT2501 and were studied in 0.66 M NaCl, in 1mM bile salts, or in 2 mM bile salts for 7 days. In comparison, rats were administered amikacin utilizing intravenous (I.V.) delivery at 200 mg/kg/day oral and at 50 mg/kg/day. Parameters that were evaluated include mortality/morbidity, clinical observations, body weights, plasma drug levels, toxicokinetic analysis, clinical pathology, necropsy observations, organ weights, and histopathology. Across dose groups MAT2501 provided 100 fold lower plasma levels of amikacin than the I.V. dose. There was a noteworthy trend toward a lower exposure on Day 7 versus Day 1 in several dose groups. The various changes seen in all treatment groups were of minimal toxicologic significance. The study found that in three different vehicle formulations, MAT2501 was well-tolerated at 50 and 200 mg/kg for 7 days.
The Company recently received Orphan Drug and QIDP designations by the U.S. Food and Drug Administration (FDA) for MAT2501 for the treatment of non-tuberculous mycobacteria (NTM) infections and expects to commence the initial study in the Phase 1 program in 2016.
MAT2501 is an orally-administered, encochleated formulation of the broad spectrum IV-only aminoglycoside antibiotic agent amikacin, which utilizes the Company’s proprietary, lipid-crystal, nanoparticle delivery technology. Amikacin is currently used to treat different types of chronic and acute bacterial infections, including NTM infections and various multidrug-resistant gram negative bacterial infections. IV-administered amikacin is associated with major side effects including nephrotoxicity and ototoxicity (permanent loss of hearing) with long-term use. MAT2501 is specifically designed to provide targeted delivery of the potent antibiotic amikacin while providing a significantly improved safety and tolerability profile. In preclinical studies MAT2501 demonstrated oral bioavailability and targeted delivery of amikacin directly to the site of infection in both pulmonary (lung) and disseminated NTM infections. Matinas recently received FDA clearance to initiate a Phase 1 clinical study of MAT2501 for the treatment of non-tuberculous mycobacterium infections. The FDA has also designated MAT2501 as a QIDP and an Orphan Drug for the treatment of NTM infections. The Company intends to initially develop MAT2501 for the treatment of NTM infections and will also explore the development of MAT2501 for the treatment of a variety of multi-drug resistant, gram negative bacterial infections. If approved, we believe MAT2501 would become the first orally bioavailable aminoglycoside and represent a significant improvement over existing therapies from a treatment and health economic perspective.
About Matinas BioPharma
Matinas BioPharma is a clinical-stage biopharmaceutical company focused on identifying and developing safe and effective broad spectrum therapeutics for the treatment of serious and life-threatening infections. The Company's proprietary, disruptive technology utilizes lipid-crystal nano-particle cochleates to nano-encapsulate existing drugs, making them safer, more tolerable, less toxic and orally bioavailable. The Company's lead drug candidate is MAT2203, an orally-administered, encochleated formulation of amphotericin B (a broad spectrum fungicidal agent). The Company has an open Investigational New Drug (IND) application for MAT2501, which is an orally-administered, encochleated formulation of amikacin (a broad spectrum aminoglycoside antibiotic agent) for acute bacterial infections, including non-tuberculous mycobacterium (NTM) and multi-drug resistant gram negative bacterial infections. In addition, the Company is exploring development and partnership options for MAT9001, a prescription-only omega-3 fatty acid-based composition under development for hypertriglyceridemia, which has shown superiority versus Vascepa® (icosapent ethyl) in reducing serum triglycerides, Total- and Non-HDL-Cholesterol, apolipoproteins and PCSK9 levels.
The Company's lead anti-infective product candidates, MAT2203 and MAT2501, position Matinas BioPharma to become a leader in the safe and effective delivery of anti-infective therapies utilizing its proprietary lipid-crystal nano-particle cochleate formulation technology.
