(NYSE AMER: MTNB), a clinical-stage biopharmaceutical company focused on improving the intracellular delivery of nucleic acids and small molecules with its lipid nanocrystal (LNC) platform delivery technology, today reported financial results for the second quarter ended June 30, 2022, along with a corporate update. “The second quarter of 2022 through today has been a period of significant execution for our Company, and especially for our lead, late stage clinical asset, MAT2203,” commented Jerome D. Jabbour, Chief Executive Officer of Matinas. “Several meetings with the U.S. Food and Drug Administration (FDA) over the past few months have provided clarity around a flexible, streamlined approval pathway for this potentially game-changing drug, based on a single Phase 3 registration trial now scheduled to commence in the first quarter of 2023. We also remain very enthusiastic about our ongoing exclusive research collaboration with BioNTech and are diligently working toward what we believe will be a mutually beneficial licensing arrangement for the application of our proprietary LNC platform in the rapidly developing mRNA space. Additional validation of the capabilities of the LNC platform and developing an internal and external pipeline of LNC-based drug candidates continue to be key objectives for Matinas in the second half of 2022 and throughout 2023.” Second Quarter 2022 Highlights and Recent Events Internal Pipeline Progress MAT2203 Enrollment continues in Cohort 4 of the ongoing EnACT study (Encochleated Oral Amphotericin for Cryptococcal Meningitis Trial) of MAT2203 (oral amphotericin B) for the treatment of cryptococcal meningitis (CM), with 42 patients (out of a total of 56) enrolled to date. Cohort 4 is testing an all-oral regimen of MAT2203 during the 14-day induction period, followed by four additional weeks of oral consolidation therapy with MAT2203. The Company anticipates reporting topline data from Cohort 4 either late in the third quarter or early in the fourth quarter of 2022. The Company recently opened an additional site in Uganda to facilitate enrollment. With guidance from multiple positive meetings with FDA over the last few months, the Company has finalized the design of a single pivotal Phase 3 registration trial for MAT2203 supporting submission of a New Drug Application (NDA) for a simplified blanket indication for the treatment of CM. The open-label trial, which the Company expects will be partially financially supported by the National Institutes of Health, involves a three arm non-inferiority design in HIV patients with CM: (A) step-down therapy with MAT2203 with treatment continuing for 2 weeks; (B) step-down therapy with MAT2203 with treatment out to 6 weeks; and (C) a standard of care (SOC) control arm of IV amphotericin induction transitioning to fluconazole. The non-inferiority margin for both the primary and key secondary endpoints will be 10% and total enrollment is expected to be approximately 270 patients, with an adaptive, de-risking design allowing for the potential for additional patients once enrollment has reached 75%. Key trial elements include: • A primary endpoint of 2-week all-cause mortality, with a pooled analysis across the two MAT2203 treatment arms compared with SOC control to support a potential indication for the treatment of CM for up to 2 weeks. • To evaluate opportunities for extending MAT2203 therapy, a key secondary analysis of 10-week relapse free survival of optimized treatment (2-weeks or 6-weeks) against SOC will be evaluated for non-inferiority. Selection of the optimal treatment regimen will be based on predefined and protocolized clinical criteria and will then form the basis for a final NDA submission. • The Company has also received recent positive feedback from EMA on both its Request for Scientific Advice and its Orphan Drug Application; this provides alignment with FDA and positions MAT2203 for global registration in key commercial markets. External Collaborations In April 2022, Matinas and BioNTech entered an exclusive research collaboration centered on the combination of Matinas’ proprietary LNC platform technology and BioNTech mRNA formats. The companies have initiated collaborative formulation work, ultimately directed toward planned preclinical testing. The parties remain in advanced discussions for a potential option to exclusively license the LNC platform for all mRNA applications. Additional recent data from an in vivo study of oral LNC-remdesivir in mice infected with SARS-CoV-2 demonstrated significant improvement in multiple histologic markers of lung injury with oral LNC remdesivir at both Day 2 and Day 5. The study was performed in collaboration with the National Institute of Allergy & Infectious Diseases and the Department of Epidemiology at the University of North Carolina at Chapel Hill. The Company expects to engage with Gilead Sciences to discuss the data and potential expansion of the LNC-remdesivir program. LYPDISO™ While data from the Company’s clinical development program for LYPDISO are compelling, the process to identify a partner to continue the development of LYPDISO has been suspended. Planned Retirement of Raphael J. Mannino, Chief Scientific Officer The Company also announced the planned retirement of Raphael J. Mannino, Chief Scientific Officer of the Company, who joined Matinas in 2015 following its acquisition of Aquarius Biotechnologies, Inc. Dr. Mannino has informed the Company that he intends to retire from employment effective December 31, 2022, whereupon he has agreed to transition to a consulting role and will continue to serve as a key strategic advisor to the Company. “On behalf of our board of directors, stockholders and employees, I want to thank Raphael for his tremendous contributions to Matinas BioPharma, and for his dedication to the LNC platform over the past 30+ years,” said Jerome D. Jabbour, Chief Executive Officer of Matinas BioPharma. “Raphael has been a visionary in the world of intracellular drug delivery and has helped to position our Company and our technology for a very bright future. We wish him all the best in retirement, but also genuinely look forward to continued contributions from him as we seek to maximize the significant opportunity afforded by this disruptive drug delivery platform.” “I am extremely proud of all of the work that has been done on the LNC platform over the years and grateful to the talented and dedicated team at Matinas for helping us to achieve remarkable clinical results with MAT2203,” commented Raphael J. Mannino, Chief Scientific Officer of Matinas. “Although I plan to take a step back in my retirement, I could not be more excited about the scientific talent we have been able to attract to the Company and the prospects for the LNC platform, especially in the field of nucleic acids. I look forward to being a key resource for Jerry and the rest of the organization as they advance and progress this exciting technology.” Second Quarter 2022 Financial Results Cash, cash equivalents and marketable securities at June 30, 2022, were approximately $38.5 million, compared to $49.6 million at December 31, 2021. Based on current projections, the Company believes that cash on hand is sufficient to fund planned operations through 2023. For the second quarter of 2022, net loss attributable to common shareholders was $5.9 million, or a net loss of $0.03 per share (basic and diluted), compared to a net loss attributable to common shareholders of $5.0 million, or a net loss of $0.02 per share (basic and diluted), for the same period in 2021. The increase was due primarily to an increase in research and development expenses, partially offset by $1.1 million of revenue resulting from the research collaboration with BioNTech SE.
