Thank you, Jody. Good afternoon, everyone and thank you for joining us. We have several recent developments to discuss today. First, we are encouraged by the feedback from the FDA that provides us with valuable guidance in developing a Phase 3 trial design with MAT2203, our oral amphotericin B product, which we believe could position this important and potentially life-saving drug for the broadest label possible for the treatment of numerous invasive fungal infections. It’s not often that the Director of the Division of Infectious Diseases elects to join a Type B meeting. And we believe this is a signal of the broad support we are receiving within FDA for the development of MAT2203. We also announced earlier today that our initial in vivo study of oral messenger RNA delivery did not demonstrate preclinical activity, which resulted in the conclusion of our collaboration agreement with BioNTech. Following a few brief remarks on these developments, I will turn the call over to Dr. Terry Matkovits to provide a more detailed update on MAT2203 and our plans to pursue marketing approval, followed by Dr. Terry Ferguson to discuss this recent development with BioNTech and our other nucleic acid programs. Finally, Keith Kucinski will review our financial results for the first quarter. You may have seen findings from a recent government study that was widely covered in the media discussing the rapid spread of deadly fungal infections in U.S. healthcare facilities. This disturbing news provides us with an even greater motivation to advance our MAT2203 program through late-stage development for broad treatment of these often deadly invasive fungal infections and toward commercialization. Our optimism for the life-saving potential for our drug has increased as we have continued to amass impressive compassionate use data through our expanded access program. One particularly compelling case was…

Thanks, Jerry. And good afternoon everyone. As Jerry mentioned, we recently received official minutes from a very productive meeting with the FDA held in April. We believe that the written feedback reflects the clinical benefit the agency sees in developing a safe, targeted, orally administered form of amphotericin B for the treatment of patients with life-threatening IFIs. FDA also expressed its desire to continue to work collaboratively with us to advance development of MAT2203, while also acknowledging the impressive novelty of our LNC platform technology and its unique pharmacokinetic profile for the delivery of amphotericin B without the toxicity associated with IV administration. Importantly, the FDA provided us with the valuable guidance for pursuing MAT2203 registration in a broader IFI indication. The agency was encouraged by the impressive results from our EnACT Phase 2 trial in cryptococcal meningitis, which demonstrated that our LNC platform was able to deliver amphotericin B in a safe, well-tolerated oral form across the blood-brain barrier with unprecedented survival outcome for oral antifungal therapy. During our meeting, FDA advised us that a larger Phase 3 trial focused solely on cryptococcal meningitis would be challenging to establish the pharmacodynamic bridge necessary to support a pharmacodynamic bridge necessary to support a streamlined 505(b)(2) approval pathway in broader IFI indications since MAT2203 would be administered as combination treatment with flucytosine or fluconazole. While surprising, following robust discussion with FDA, we now believe that the revised Phase 3 aspergillus IFI study design, assessing the efficacy and safety of MAT2203 as early step down monotherapy in a comparative non-inferiority Phase 3 trial in aspergillus should establish the desired pharmacodynamic bridge to unlock the 505(b)(2) pathway to indications for the treatment of other invasive fungal infections. We expect this strategy to result in the broadest possible label for MAT2203, utilizing the most…

Thanks Terry, and good afternoon everyone. We very recently received results of an initial in vivo study of an oral mRNA delivery formulation that was conducted in collaboration with BioNTech. The results did not demonstrate oral preclinical activity. By way of background this study was conducted in healthy mice and involved oral administration of a unique, proprietary, non-LNC formulation of BioNTech-supplied reporter firefly luciferase mRNA. This new proprietary, phosphatidylserine-containing nano-formulation is distinct from our conventional LNCs, and was developed by scientists at Matinas to handle the physical complexity and biological fragility of mRNA and other large oligonucleotides. We had been quite optimistic about moving into the oral study as this new delivery technology had successfully delivered mRNA in vitro in multiple cell lines. Because of the timelines required under the BioNTech collaboration we opted to bring it forward for oral in vivo evaluation. Unfortunately, we were not successful in this initial study and our collaboration agreement with BioNTech has been concluded. In parallel to our work with BioNTech, we conducted additional internal in vivo studies with similar non-LNC mRNA formulations, and these have shown significant activity with systemic administered both intramuscularly and intraperitoneally. Our new mRNA formulations have also demonstrated impressive structural stability and continued biological activity out to at least 17 weeks at 4-degree Celsius, which compares favorably to lipid nanoparticles or LNPs. Matinas has filed numerous provisional patent applications based on these novel, unique phosphatidylserine-based formulations. With the exclusivity constraints of the BioNTech agreement expiring last month, we were able to pursue interest from others working with mRNA. We have taken this opportunity to shift our work under our agreement with national resilience to focus more on mRNA, including in vitro delivery of reporter oligonucleotides with LNP reference comparators, delivery of even larger reporter oligonucleotides, and ultimately extending…

Thank you, Terry. Today we reported revenue for the first quarter of 2023 of $1.1 million, which was generated from our research collaborations with BioNTech and Genentech. We had no revenue for the first quarter of 2022. Total cost and expenses for the first quarter of 2023 were $6 million compared with $7 million for the first quarter of 2022, the decrease was primarily attributable to lower manufacturing costs of clinical trial materials partially offset by higher headcount. Our net loss for the first quarter of 2023 was $5.5 million or $0.03 per share, this compares with the net loss for the first quarter of 2022 of $6 million, also $0.03 per share. Our cash, cash equivalents and marketable securities as of March 31, 2023 were $24.9 million. Based on current projections, we believe our cash is sufficient to fund planned operations into the second half of 2024. With that, I’ll turn the call back to Jerry.

Jerry Jabbour

Analyst

Thanks Keith. In summary, MAT2203 has been established as a highly promising treatment for serious and often deadly fungal infections. Survival data from our Phase 2 EnACT study in cryptococcal meningitis combined with the growing evidence of clinical impact in the treatment of invasive fungal infections through compassionate use in our expanded access program have provided a solid basis upon which to engage FDA in a thoughtful and productive discussion on the Phase 3 program designed to have the broadest clinical impact, resulting in a significant commercial opportunity for potential partners. FDA’s feedback, guidance and willingness to engage collaboratively have placed us in a stronger position to advance development of this life-saving drug. We’re excited to finalize and submit our planned protocol to FDA for final review and obtain a big piece of the puzzle on unlocking partner value and government funding support. We remain on track with a later stage impactful clinical asset and one we continue to build a company around. While the recent in vivo study result with a novel oral messenger RNA delivery formulation, we conducted with BioNTech may represent a short-term setback. We are reminded that our goal of oral delivery of messenger RNA is ambitious and has to date not been accomplished by anyone else. Through our collaboration with BioNTech, we generated promising in vitro data followed by in vivo data demonstrating that our delivery technology could successfully deliver large nucleic acids like messenger RNA systemically. Even if the Holy Grail of oral delivery remains elusive at this point in time. We remain committed to expanding our understanding of the capabilities of our platform technologies and continue to believe they have the potential to provide differentiated delivery of nucleic acids through programs with National Resilience with messenger RNA and internal programs focused on LNC delivery of siRNA and small molecules. The second half of this year should yield multiple opportunities for additional data and expansion of our platform. We’re grateful for your continued support and will continue to diligently advance our promising technologies and resulting therapies for the benefits of patients globally. With that, we have finished our prepared remarks. And I will now turn the call back over to our operator, Paul, to facilitate a question-and-answer session. Paul?

Thanks Paul. While we’re waiting for that first question, I’d like to mention that we have been invited to present at the JMP Healthcare Conference next Monday, May 15 in New York. The presentation will be webcast and will be available on the IR calendar page of the company website. Okay, Paul, can we have that first question, we’re ready.

Hey Jerry. Thanks for the presentation. I really appreciate it. Just had a question about the BioNTech collaboration. Over the past year you had mentioned that the deal was almost over the finish line or near the finish line. Can you just talk a little bit about what happened, and where we are right now with BioNTech?

Jerry Jabbour

Analyst

Sure. I didn’t catch your name. What’s your name, and where you’re from?

Unidentified Analyst

Gregg. Gregg, I’m an individual investor, Alexander.

Jerry Jabbour

Analyst

Okay. So Gregg, thanks for the question. I know that the BioNTech relationship has been on the minds of investors since we first announced it last April. And it’s a relationship we’re really excited about and scientifically being able to collaborate with a group like BioNTech, represented a great opportunity for us. And BioNTech came to the table with money on the table and ready to support us, and – but I think everyone recognizes that and certainly BioNTech did too, that we went into that relationship, having not yet demonstrated our ability to encapsulate and deliver messenger RNA. But the opportunity that the oral bioavailability could present for that particular nucleic acid was worth the work. And so the parties collaborated together over a year, certain aspects of that agreement, put BioNTech in position to want to potentially discuss a license agreement, which the parties did over the course of the last 12 months. As the year advanced and the work proceeded we developed a series of encouraging in vitro data where we showed the ability to encapsulate and get penetration essentially in a lab. And the decision was made at that time by BioNTech that they would like to wait for the in vivo data. And so we were full steam ahead towards an in vivo study, one-single study that BioNTech planned. We worked with their reporter, luciferase messenger RNA, encapsulated it, gave that product to them for the conduct of that study in April. And very recently, they shared the results of that study. Due to constraints on that agreement, I can’t go into a lot of the details around what was discussed with BioNTech, but they made it clear and we parted ways in a very cordial manner, but that they were going to focus on…

Thank you. Our next question is from Julian Harrison with BTIG. Please proceed with your question.

Julian Harrison

Analyst

Hi. Congrats on the progress, and thank you for taking my questions. First on MAT2203, I was wondering if you could just remind us that the opportunity in post-transplant prophylaxis patients and what the development strategy might be there going forward? And then on the LNC technology, you noted that you plan to continue with in vivo distribution and efficacy studies in the back half of this year. I’m curious if this will include oral dosing or are you going to focus in other routes of administration there? And also when might we expect data from these additional studies? Thanks.

Jerry Jabbour

Analyst

Sure. Julian, thanks very much, and welcome to the story. We’re thrilled to have you working with us with BTIG. So I want Dr. Matkovits to weigh in here, but prophylaxis has long been in our sights for those investors that have been around for a number of years. Prophylaxis is actually where this drug was targeted and heading based upon its unique profile. Any time you can take a broad spectrum drug that’s going to be effective against a lot of different bugs, works in immunocompromised patients and has the ability to be given orally given the increased incidence of immunocompromised patients developing fungal infections, prophylaxis is a natural place you would take a drug like MAT2203. When Dr. Matkovits joined, we smartly sort of pivoted that to let’s prove we can treat the fungal infections first, but we never lost sight of the opportunity that prophylaxis brings. And certainly, it is there and very much a large part of the value proposition. But Terry, why don’t you shed a little light on that?

Terry Matkovits

Analyst

Sure. Thanks, Jerry, and thanks for the question, Julian. So we believe that through the clinical program that we have generated data from in patients with invasive fungal infections, we’ve really highlighted the three critical attributes of our oral MAT2203 that we believe ideally positions this drug for the prophylaxis setting in patients post-transplant. And that includes the ability to administer orally the favorable long-term safety profile of our drug and the significant safety profile that allows the drug to be administered without any risk or any drug-drug interactions. So those three pivotal components of our drug, we believe, ideally and uniquely positions our drug to really replace oral azole therapy in the prophylaxis setting. And in fact, I can say from our recent experience at ECCMID during IDWeek last year, we have had significant inbound interest clinicians, who are treating patients, who are immunocompromised and has expressed interest in being part of our clinical program as we expand into the prophylaxis indication.

Julian Harrison

Analyst

Great, thank you.

Jerry Jabbour

And then, Julian, let me touch on the second part of your question, nucleic acids. One of the best things that come out of the last year, specifically our work with BioNTech is we showed we have some pretty impressive scientists internally. And I say that because we started utilizing lipid nano-crystals, but when we recognized that there was going to have to be optimization there that was going to change the time lines of our relationship with BioNTech, in less than six months, the internal team here essentially came up with a novel phosphatidylserine based lipid-nanoparticle that didn’t have cytotoxicity in vivo, that was able to target cells, that was able to demonstrate activity and that continued in an in vivo environment. And so when you think about the historical legacy of lipid nanoparticles in the 20-plus years it took to get a therapy approved using lipid nanoparticles, the fact that the team here was able to do that in such a short period of time is frankly remarkable. And it gives us a couple of different opportunities. We do think that there is a size issue with the larger oligos, which represent a challenge for lipid nanocrystals, getting things to embed themselves in the buy layer. And so it gives us an opportunity to do two things. So with the National Resilience, we’re going to be focused more on systemic delivery, a huge need for IV, particularly in the vaccine area. So, we’re going to work with them utilizing this next-generation phosphatidylserine nanoparticle technology. But our internal work, smaller oligos are different. So siRNA for us still represents an important oral opportunity. We are targeting inflammation in oncology there, but it will be at least at present, our belief is that we can successfully encapsulate siRNA and deliver it with our LNCs. We’ve done that with other smaller oligos. But maybe Terry Ferguson, you want to shed some light on that. But our expectation, Julian, in the second half of this year is that we’ll have data with both.

Terry Ferguson

Analyst

Yes, Jerry, to build on what you were saying, I think, that it’s important to recognize that with the – as a result of the work that we’ve been doing with mRNA and our first opportunity with mRNA, we learned a lot. And it’s a different kind of cargo to be able to deliver. And we developed a specialized system for delivery of large oligos, it just didn’t work orally. Our LNC technology, the traditional LNC technology, the nanocrystals is available orally. Dr. Matkovits highlighted the success and progress of our MAT2203 program. But our ongoing work focusing on the smaller oligos, the siRNAs, the ASOs is taking advantage of exactly that technology and the strengths of what we’ve been able to prove and prior work that has shown delivery in vitro and in vivo of small oligos. So that work will probably be more focused in the oral direction.

Julian Harrison

Thanks, Paul. Thanks to everyone for joining us today and for your interest in Matinas. We are very excited about our company’s future, we are very excited about our ability to save lives with MAT2203 and we are very excited about the potential we have with a number of different delivery technologies going forward in nucleic acid. We look forward to reporting our progress during our Q2 investor call in August. And should we have developments before then, we certainly will be informing the market as soon as we can. Thanks, and have a great evening.
