Item 8.01. Other Events.

On January 30, 2023, the Company announced, among other things, that:

LNCPlatform Internal Data Generated

Developed<br> multiple flow cytometry and florescence cell-based assays with compelling validations of intracellular uptake and gene expression<br> with our LNC formulations.
Successful<br> delivery of multiple larger nucleic acids coded with reporter genes across multiple cell lines (HeLa, HEK293, A375, etc.).
Multiple<br> oligonucleotide formulations that have demonstrated strong gene expression potency at nanogram per well dosage level, comparable<br> to industry standard Lipofectamine.
Internal<br> mRNA formulations that have shown excellent stability and remain biologically active over 10 weeks at 4^o^C storage conditions.
Multiple<br> formulations have shown little to no cytotoxicity during in vitro cell viability evaluations supporting an anticipated favorable<br> safety profile compared with other drug delivery technologies.

LNCInternal Pipeline Development

Based<br> on historical data with the LNC platform, along with recent learnings from internal work and its collaborations, the Company believes<br> the greatest chance of success in developing our own pipeline of nucleic acid drug candidates is with smaller oligonucleotides like<br> antisense oligonucleotides (ASOs) and small interfering or silencing RNA (siRNAs). The properties of these molecules are particularly<br> suited for our LNC platform, and the Company believes that its technology can facilitate oral delivery and extrahepatic targeting<br> – currently two of the greatest challenges in this developing area.
The<br> Company has commenced a research program focused on ASOs/siRNAs that it expects will generate in vitro delivery data early<br> in the second quarter of this year, followed by multiple in vivo biodistribution and animal efficacy studies in the second<br> half of 2023. If successful, the Company anticipates being in position to identify our next internal product candidate in late 2023.<br> The Company believes success in these studies could position it to develop an entire pipeline of ASO and siRNA therapies.

MAT2203(oral amphotericin B) Program

In<br> November 2022, the Biomedical Advanced Research and Development Authority (BARDA) announced an initiative seeking private sector<br> partners developing late-stage, broad-spectrum antifungal drugs to treat high priority fungal infections, including aspergillus,<br> mucormycosis, and certain forms of candidiasis. BARDA has solicited proposals from industry, and the Company believes MAT2203 is<br> a strong candidate for funding based upon its oral, well-tolerated and broad-spectrum profile, along with its recent clinical success<br> in Phase 2 with cryptococcal meningitis. The Company is scheduled to meet with BARDA during the first quarter of 2023 and has included<br> all associated costs for full development for MAT2203 in its proposal. The Company believes pausing the start of its Phase 3 clinical<br> trial in cryptococcal meningitis pending the outcome of BARDA’s evaluation of MAT2203 is the best possible course for this<br> life-saving drug. In 2021, BARDA funding for vaccines stood at $36.9 billion, therapeutics at $14.1 billion, and diagnostics at $51<br> million.
The<br> Company is preparing to submit a formal Meeting Request to the U.S. Food and Drug Administration (FDA) to discuss plans for a second<br> Phase 3 study to assess the efficacy, safety, and tolerability of MAT2203 in patients with serious, life-threatening invasive fungal<br> infections with limited treatment options. The protocol synopsis currently includes the treatment of four invasive fungal infections:<br> invasive aspergillosis, invasive candidiasis, chronic coccidioidomycosis (Valley Fever), and invasive Mucormycosis. The Company’s<br> strategy is to leverage the success and data from EnACT to limit the required size of this study. The Company currently plans to<br> enroll approximately 100 patients in a single arm design with no head-to-head active comparator, which it believes should be acceptable<br> given historical precedent and the challenges associated with the target patient population to be evaluated. The Company anticipates<br> meeting with FDA in the second quarter of 2023 to discuss its proposed design and strategy for approval. The Company believes that<br> FDA guidance on this Phase 3 study is critical to its BARDA proposal as well as to prospective domestic and global partners currently<br> evaluating MAT2203, based on feedback received to date.
The<br> success of MAT2203 in the EnACT Phase 2 clinical trial in cryptococcal meningitis has attracted the attention of clinicians and patients<br> without viable options for the treatment of a variety of fungal infections for which amphotericin B may be suitable, except for significant<br> concerns relating to the toxicity of the currently available intravenous formulations of amphotericin B. Currently, there are four<br> (4) patients who have been approved by FDA to receive MAT2203 on an emergency use basis since August of 2022, including one patient<br> suffering from both mucor and aspergillosis. Overall, these patients have responded well to treatment with notable clinical<br> improvements. The Company will continue to evaluate opportunities to provide MAT2203 on an emergency basis for patients as it believes<br> these are opportunities to showcase the safety and efficacy of MAT2203 outside clinical trial settings which represent important<br> additional patient data for both FDA and prospective partners to review.

FinancialOutlook

The<br> Company’s preliminary estimate of cash, cash equivalents and marketable securities at December 31, 2022, is approximately $28.8<br> million, subject to completion of the audit of the Company’s consolidated financial statements for the year ended December<br> 31, 2023, compared to $49.6 million at December 31, 2021. This amount may differ from the amount that will be reflected in the Company’s<br> audited 2022 financial statements. Additional information and disclosures are required for a more complete understanding of the Company’s<br> financial position and results of operations as of December 31, 2022. Based on current projections, the Company believes that cash<br> on hand is sufficient to fund planned operations into the second quarter of 2024.

ConferenceCall and Live Audio Webcast Scheduled Today, January 30 at 4:30 p.m. ET

BEDMINSTER,NJ, Jan. 30, 2023 –Matinas BioPharma (NYSE AMER: MTNB, Matinas), 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 its ongoing programs and discussing its strategic outlook for 2023.

“In 2022 we successfully demonstrated that MAT2203, our lead asset based on our lipid nanocrystal (LNC) delivery platform, could safely and effectively deliver unprecedented survival outcomes, with an oral therapy, for patients suffering from deadly fungal infections,” commented Jerome D. Jabbour, Chief Executive Officer of Matinas. “Our success with smaller molecules increased our confidence in the platform and empowered us to focus on what we believe is the real future of medicine – the ability to safely and effectively deliver therapies that affect the genetic mechanisms underlying disease. We are striving to create an internal and external pipeline of product candidates in the nucleic acid and gene therapy space that take advantage of the unique and proprietary nature of our delivery technologies. Our ongoing collaborations with BioNTech and, recently, National Resilience, have aligned Matinas with two of the world’s leading companies in the gene therapy space. These collaborations were designed to accelerate the overall development of our LNC platform and maximize the value we can obtain from third parties while providing us with critical data and information necessary to establish and develop an internal pipeline of nucleic acid therapies.”

Jabbour added, “During these uncertain economic times, we remain cognizant of our cash resources and have chosen to prioritize those activities which we believe will create the greatest shareholder value. Through these strategic choices, we have extended our cash runway into the second quarter of 2024, well beyond potential value-creating catalysts and near-term opportunities for non-dilutive funding from LNC partners and/or BARDA. We could not be more excited about what we are building at Matinas, and we believe that 2023 will be a great year for the Company and its shareholders.”
