BEDMINSTER, N.J., Aug. 10, 2021 (GLOBE NEWSWIRE) -- Matinas BioPharma Holdings, Inc. (NYSE AMER: MTNB), a clinical-stage biopharmaceutical company focused on improving the intracellular delivery of critical therapeutics through its paradigm-changing lipid nanocrystal (LNC) platform delivery technology, today reported financial results for the second quarter ended June 30, 2021, along with a corporate update.

Second Quarter Highlights and Looking Ahead

Completed patient enrollment in Cohort 2 of the EnACT study (Encochleated Oral Amphotericin for Cryptococcal Meningitis Trial); DSMB evaluation of available safety and efficacy data from Cohort 2 expected in September 2021. The Company plans to announce efficacy and safety data from the first two cohorts of EnACT together with Dr. David Boulware, Principal Investigator, following the DSMB evaluation.
Following the EnACT data announcement, the Company plans to meet with the U.S. Food and Drug Administration (FDA) in the fourth quarter of 2021 to discuss the potential for approval of MAT2203 under one or more accelerated regulatory pathways for important anti-infective medicines that address significant unmet medical needs in small or vulnerable patient populations.
The Company expects to initiate a Phase 1 single ascending dose (SAD) pharmacokinetic study of MAT2501 in healthy volunteers in the fourth quarter of 2021. Initiation of the Phase 1 SAD study follows positive feedback received from the FDA on the Company's ongoing preclinical toxicology and efficacy studies of MAT2501 conducted in collaboration with the Cystic Fibrosis Foundation (CFF).
The Company and NIAID have successfully completed in vitro studies of various LNC formulations of Gilead's antiviral drug remdesivir. Selected LNC-remdesivir formulations were tested for antiviral activity against SARS-CoV2 WA strain in Caco-2 cells. Unformulated remdesivir active (GS-5734, in DMSO) was tested as a comparison. LNC formulations tested in this model demonstrated meaningful antiviral activity compared to free remdesivir, with a favorable toxicity profile. Based on these results, NIAID is preparing to initiate an in vivo efficacy study of the most potent LNC-remdesivir formulation. Results are expected in the fourth quarter of 2021.

"We are very excited to have provided an in-depth look at our LNC platform during our R&D Day in June. We believe that our platform has the potential to become the next generation in safe and effective intracellular drug delivery," commented Jerome D. Jabbour, Chief Executive Officer of Matinas. "We have made great progress with MAT2203 and MAT2501, both of which represent large potential commercial opportunities for Matinas. Completion of Cohort 2 of EnACT provides an important milestone and further validation for our LNC platform. In addition to potentially demonstrating that MAT2203 can be a safe and effective step-down oral therapy for patients with cryptococcal meningitis, we believe that the data from Cohort 2 will support a key regulatory interaction later in 2021 for a potential early registration pathway for MAT2203 as step-down therapy for patients suffering from cryptococcal meningitis. In addition, recent positive feedback from the FDA on our ongoing preclinical program with MAT2501 now positions us to initiate the Phase 1 SAD study for MAT2501 in the fourth quarter of 2021."

"Finally, we are extremely pleased with the positive in vitro data that we have reviewed from NIAID with our LNC-remdesivir formulations," continued Mr. Jabbour. "The success of our LNC platform in vitro has provided further evidence that our LNC platform can be utilized to orally administer drugs currently otherwise limited to intravenous delivery. An oral version of Gilead's remdesivir could become an essential tool in the fight against COVID-19, as it may permit administration earlier in the disease course as well as potential for prophylactic use, should clinical studies validate such an approach. We are honored to continue to partner with NIAID on this important project and look forward to additional in vivo data later in 2021."

Second Quarter 2021 Financial Results

Cash, cash equivalents and marketable securities at June 30, 2021, were approximately $59.8 million, compared to $58.7 million at December 31, 2020. Based on current projections, the Company believes that cash on hand is sufficient to fund operations into 2024.

For the second quarter of 2021, net loss attributable to common shareholders was $5.0 million, or a net loss of $0.02 per share (basic and diluted), compared to a net loss attributable to common shareholders of $5.8 million, or a net loss of $0.03 per share (basic and diluted), for the same period in 2020. The decrease was due primarily to a reduction in research and development expenses, as more fully described below.

Research and development expenses for the second quarter of 2021 were $2.5 million, compared to $3.4 million for the same period in 2020. The decrease was primarily due to the completion of the ENHANCE-IT study of LYPDISO in January 2021.

General and administrative expenses for the second quarter of 2021 were $2.3 million, essentially unchanged compared to $2.4 million in the same period in 2020.

Conference Call and Webcast Details

The Company will host a live conference call and webcast to discuss these results today, Tuesday, August 10, 2021, at 8:00 a.m. ET.

To participate in the call, please dial (877) 407-5976 (Toll-Free) or (412) 902-0031 (Toll) and reference conference ID 13720567. The live webcast will be accessible on the Investors section of Matinas' website, www.matinasbiopharma.com, and archived for 90 days.

About Matinas BioPharma

Matinas BioPharma is a biopharmaceutical company focused on improving the intracellular delivery of critical therapeutics through its paradigm-changing lipid nanocrystal (LNC) delivery platform. The Company is developing its own internal portfolio of products as well as partnering with leading pharmaceutical companies to develop new formulations that take full advantage of the unique characteristics of the LNC platform.

Preclinical and clinical data have demonstrated that this novel technology can provide solutions to many of the complex 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 in both the formulation and route of administration (including oral), position Matinas' LNC technology to potentially become the preferred next-generation intracellular drug delivery vehicle and an important improvement 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. EnACT is nearing the completion of enrollment of its second cohort of patients, with the next DSMB evaluation of safety and efficacy data anticipated to occur in September 2021.

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 expects to enter a Phase 1 human clinical trial later in 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 (CF).

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®. The Company has initiated a process to identity and potentially secure a partner to continue development of LYPDISO.
