BEDMINSTER, N.J., Jan. 25, 2022 (GLOBE NEWSWIRE) -- Matinas BioPharma Holdings, Inc. (NYSE AMER: MTNB), a clinical-stage biopharmaceutical company focused on redefining the intracellular delivery of nucleic acids and small molecules with its lipid nanocrystal (LNC) platform technology, today is providing a business update on each of its ongoing programs and discussing its strategic outlook for 2022.

“We made tremendous progress in 2021, completely transitioning our Company and significantly advancing our LNC platform technology,” commented Jerome D. Jabbour, Chief Executive Officer of Matinas. “Despite the resurgence of COVID-19 with both Delta and Omicron variants, our team was able to deliver compelling data for MAT2203 in the first three cohorts of the EnACT trial, which then facilitated an important and highly productive End of Phase 2 meeting with the U.S. Food and Drug Administration (FDA) in December of 2021. Based upon FDA’s support and feedback, we are preparing to expand the EnACT trial to provide additional confirmatory data in support of MAT2203 as step-down therapy for induction treatment, which we believe could position us to submit a New Drug Application (NDA) in late 2023.”

Jabbour added, “We continue to be pleased with our collaborations with Genentech and NIAID/Gilead, and each has yielded encouraging data in support of our LNC platform which will lead to further studies during 2022. Finally, during 2021 we conducted an internal evaluation of our LNC platform and believe that applying our proprietary and differentiated intracellular delivery technology to complex nucleic acids represents a highly promising opportunity. We anticipate expanding the application of our technology into this area, both internally and in partnership with carefully selected third parties during 2022.”

Key Program Updates and Anticipated Upcoming Milestones

MAT2203 Program (oral amphotericin B, with targeted delivery, under development for the treatment and prevention of invasive fungal infections, including cryptococcal meningitis)

  • Additional analyses of final data from Cohort 2 of EnACT demonstrated (i) survival at Day 30 (early survival) of 98% in patients receiving MAT2203 vs. 88% in patients receiving IV Amphotericin B (SOC); and (ii) culture conversion (sterility) assessed at any time during the trial of 97% in patients receiving MAT2203 and 76% in patients receiving SOC.
  • Positive FDA Meeting in December 2021 reinforced FDA’s ongoing commitment to anti-infective drug development generally and to MAT2203 specifically. The FDA expressed no concerns with any data generated to date related to the efficacy, safety, or tolerability of MAT2203. Additional confirmatory evidence was requested for an indication for step-down therapy during induction treatment, but there was no requirement for a separate stand-alone study or enrollment of U.S. patients. The FDA expressed openness to an expansion of EnACT to include a new Cohort 5 to run alongside Cohort 4 in Uganda, increasing the number of clinical sites from two to five to streamline the development program in support of an accelerated NDA submission. The Company is planning to meet with FDA in the second quarter of 2022 to finalize cohort design, including sample size required for non-inferiority and discussing potential primary endpoint of 30-day survival. NIH financial support of EnACT expansion anticipated and the Company continues to evaluate the timing for submission of an application for Breakthrough Designation.
  • Key chemistry, manufacturing, and controls (CMC) meeting with FDA to be scheduled late in the first quarter of 2022 to discuss and evaluate MAT2203 formulation in support of a potential NDA submission in late 2023.
  • Cohort 4 of EnACT has commenced in Uganda, with six patients enrolled to date. Cohort 4 is designed to study an all-oral regimen of MAT2203 during the 14-day induction period, followed by four additional weeks of oral consolidation therapy with MAT2203. Cohort 4 is comprised of 40 patients on MAT2203 and a control group of 16 patients receiving IV amphotericin B. Enrollment in this open-label cohort is expected to complete in the second quarter of 2022, with availability of topline interim data anticipated in the third quarter of 2022.
  • Additional preclinical studies of MAT2203 are planned to investigate the treatment of invasive fungal infections, such as Candida auris and mucormycosis (black fungus), to position MAT2203 for label expansion. Data is expected in the second half of 2022.
  • Company plans to submit a formal Request for Scientific Advice to the European Medicines Agency (EMA) by the second quarter of 2022 to align and plan for expanding the regulatory footprint for MAT2203 globally.

LNC Platform Collaborations

  • NIAID/Gilead – In the fourth quarter of 2021, the National Institute of Allergy and Infectious Diseases (NIAID), together with the Department of Epidemiology at the University of North Carolina at Chapel Hill (UNC), conducted an in vivo test of our LNC formulation of Gilead Science’s remdesivir (LNC-RDV) in a standard genetically modified mouse model of SARS-CoV-2 infection. In this animal model, orally administered LNC-RDV reduced viral titers and improved clinical parameters of body weight and congestion scores five days following infection, with effects similar to those seen with subcutaneous administered remdesivir. Following discussion with both NIAID and Gilead, these highly encouraging results position LNC-RDV for further in vivo work to be conducted at UNC and supported by NIAID. This preclinical study is anticipated to commence late in the first quarter of 2022, with data expected in the second half of 2022.
  • Genentech – Genentech recently extended this collaboration for another year, through 2022. The original agreement provided for cooperation on up to three proprietary Genentech compounds for initial in vitro testing. Two of the programs have been completed. Each demonstrated the successful intracellular delivery of LNC-formulated small molecules and oligonucleotides, without accompanying toxicity. Genentech is evaluating the third proprietary compound to provide the Company for testing, and the Company anticipates additional data from this program during 2022.

MAT2501 Program (oral amikacin, with targeted delivery, under development for the treatment of nontuberculous mycobacterial (NTM) lung disease, including infections in patients with cystic fibrosis (CF))

  • A single ascending dose (SAD) study of MAT2501 in healthy volunteers is ongoing with data expected later in the second quarter of 2022.
  • In the fourth quarter of 2021, the Cystic Fibrosis Foundation (CFF) provided an additional grant award in connection with ongoing preclinical work in support of MAT2501, bringing the total amount of CFF financial support for MAT2501 to over $4.5 million.
  • Long-term preclinical toxicology studies planned for 2022 and protocol design for Phase 2 in consultation with the CFF are ongoing. Phase 2 trials of MAT2501 for the treatment of NTM are expected to commence in 2023, pending additional financial support from the CFF.

LYPDISO™ Program (next generation, prescription-only omega-3 fatty acid-based composition under development for treatment of cardiovascular and metabolic conditions, including hypertriglyceridemia)

  • A global process to identity and potentially secure a partner to continue development of LYPDISO remains ongoing. Interest in this legacy non-LNC based cardiovascular asset has emerged from a collection of companies and Matinas is evaluating several strategic alternatives. Further update is anticipated in the second quarter of 2022.

Financial Outlook

The Company’s preliminary, unaudited estimate of cash, cash equivalents and marketable securities at December 31, 2021, is approximately $49.9 million, subject to completion of the audit of the Company’s consolidated financial statements for the year ended December 31, 2021. This compares to $58.7 million at December 31, 2020. Based on current projections, the Company believes that cash on hand is sufficient to fund planned operations through 2023.

At the Special Meeting of Stockholders held on January 26, 2021, stockholders of Matinas approved an amendment to the Company’s Certificate of Incorporation to effect a reverse stock split of our common stock at a ratio in the range of 1-for-2 to 1-for-15, with such reverse stock split to be effected at such ratio, time, and date, if at all, as determined by the Company’s Board of Directors in its sole discretion. Following a review of the Company and its strategic positioning, the Board of Directors has determined that it is not in the best interest of the Company or its stockholders to effect a reverse split.

About Matinas BioPharma

Matinas BioPharma is a biopharmaceutical company focused on redefining the intracellular delivery of nucleic acids and small molecules with its lipid nanocrystal (LNC) platform technology. The Company is developing its own internal portfolio of products as well as partnering with leading pharmaceutical companies to develop novel formulations that capitalize on the unique characteristics of the LNC platform.

Preclinical and clinical data have demonstrated that this novel technology can provide solutions to many of the challenges in achieving safe and effective intracellular delivery, for both small molecules and larger, more complex molecules, such as mRNA, DNA plasmids, antisense oligonucleotides and vaccines. The combination of a unique mechanism of action and flexibility with formulation and in route of administration (including oral), position Matinas’ LNC technology to potentially become the preferred next-generation intracellular drug delivery vehicle with distinct advantages over both lipid nanoparticles and viral vectors.

MAT2203 is an oral, LNC formulation of the highly effective, but also highly toxic, antifungal medicine amphotericin B, primarily used as a first-line treatment for invasive fungal infections. MAT2203 is currently in a Phase 2 open-label, sequential cohort study (EnACT) in HIV-infected patients with cryptococcal meningitis. The DSMB unanimously approved the progression of EnACT into Cohort 4 in December of 2021. Cohort 4 commenced in January of 2022, with data expected in the second half of 2022.

MAT2501 is an oral, LNC formulation of the broad-spectrum aminoglycoside antibiotic amikacin, primarily used to treat chronic and acute bacterial infections. With the support of the Cystic Fibrosis Foundation, MAT2501 is currently undergoing important preclinical studies and commenced a Phase 1 human clinical trial in the fourth quarter of 2021. MAT2501 would be the first and only oral aminoglycoside, and is being positioned with an initial indication for the treatment of nontuberculous mycobacterial (NTM) lung disease, including infections in patients with cystic fibrosis.

LYPDISO™, is a prescription-only omega-3 fatty acid-based composition, comprised primarily of EPA and DPA, intended for the treatment of cardiovascular and metabolic conditions. This next-generation omega-3 therapy has been shown in two head-to-head studies to provide effective triglyceride-lowering and significantly higher EPA blood levels than Vascepa®. A global process to identity and potentially secure a partner to continue development of LYPDISO remains ongoing.
