Matinas BioPharma Announces Publication of Results from the Phase 2 EnACT Clinical Trial of MAT2203 in the IDSA Journal Clinical Infectious Diseases

BEDMINSTER, N.J., Aug. 22, 2023 (GLOBE NEWSWIRE) -- (NYSE American: MTNB), a clinical-stage biopharmaceutical company focused on delivering groundbreaking therapies using its lipid nanocrystal (LNC) platform delivery technology, announces that University of Minnesota Medical School researchers published results from the Phase 2 EnACT trial evaluating MAT2203 for the treatment of cryptococcal meningitis as a and Editor’s Choice in Clinical Infectious Diseases, an official publication of the Infectious Diseases Society of America (IDSA). MAT2203 is an oral and non-toxic, LNC formulation of the potent antifungal drug amphotericin B.

David Boulware, MD, MPH, the senior investigator of the EnACT trial and infectious disease physician at the University of Minnesota, commented, “An orally administered amphotericin that is broad spectrum and non-toxic sounds like the holy grail of antifungal medicines. While further clinical trials are needed in other fungal conditions, the EnACT trial establishes proof of concept for the safe and effective treatment of invasive fungal infections. In this randomized trial of 141 HIV-positive individuals afflicted by life-threatening cryptococcal meningitis, the oral amphotericin MAT2203 product combined with oral flucytosine appears promising for cryptococcal meningitis with antifungal activity, similar survival, and less toxicity than intravenous amphotericin B. With six weeks of LNC-enabled oral amphotericin B, statistically fewer lab abnormalities occurred than with one week of intravenous amphotericin B.”

“We are very pleased that the important EnACT data are being shared with the clinical and scientific community at large through publication in this peer-reviewed journal,” said . “The results from EnACT in cryptococcal meningitis and our experience with patients enrolled in our Compassionate/Expanded Use Access Program support our belief that MAT2203 has the potential to become an important part of the regimen for treatment of invasive fungal infections, including in the highest-need patients who require longer-term treatment and have limited or no treatment options. The publication of the EnACT data in Clinical Infectious Diseases is yet another milestone for our development program. We would like to thank all the EnACT participants, our dedicated investigators, and the entire clinical study team in Uganda for their commitment to this important clinical trial.”

About the EnACT Phase 2 Study

EnACT was a Phase 2 prospective, randomized, open-label, sequential cohort study, financially supported by the National Institute of Neurological Disorders and Stroke (NINDS) of the National Institutes of Health (NIH), evaluating the safety, tolerability, and efficacy of MAT2203 in 100 HIV-positive persons with cryptococcal meningitis compared to 41 persons randomized to receive standard of care intravenous amphotericin B.

The EnACT trial included a total of four cohorts of participants, with the first two cohorts testing MAT2203 as early step-down therapy following initial treatment with IV amphotericin B during the induction period, and the second two cohorts testing MAT2203 as potentially all oral therapy. Cohorts 1 and 3 were safety lead-ins to Cohorts 2 and 4, respectively. The induction period for all patients in each cohort (active or control) was 14 days, followed by an additional four weeks of treatment (active or control) during a consolidation/maintenance period.

About Matinas BioPharma

Matinas BioPharma is a biopharmaceutical company focused on delivering groundbreaking therapies using its lipid nanocrystal (LNC) platform delivery technology.

Matinas’ lead LNC-based therapy is MAT2203, an oral formulation of the broad-spectrum antifungal drug amphotericin B, which although highly potent, can be associated with significant toxicity. Matinas’ LNC platform provides oral delivery of amphotericin B without the significant nephrotoxicity otherwise associated with IV-delivered formulations. MAT2203 also allows for safe, longer-term use outside of a hospital setting, which could have substantial favorable pharmacoeconomic impact. MAT2203 successfully completed the Phase 2 EnACT program in cryptococcal meningitis, meeting its primary endpoint and achieving robust survival. MAT2203 is being positioned for a single pivotal Phase 3 study in the treatment of aspergillosis and other invasive fungal infections, including mucormycosis, Candida auris and other candidiasis, and certain endemic fungal infections in persons with limited treatment options who are unable to be treated with azoles or echinocandins for reasons related to drug-drug interactions, resistance or for whom these antifungal agents are unable to be used for other clinical reasons.

In addition to MAT2203, preclinical and clinical data have demonstrated that this novel technology can provide solutions to many of the challenges standing in the way of achieving safe and effective intracellular delivery of both small molecules and larger, more complex molecular cargos such as RNAi, antisense oligonucleotides, and vaccines. The combination of its unique mechanism of action and flexibility with routes of administration (including oral) positions Matinas’ LNC technology to potentially become a preferred next-generation intracellular drug delivery platform.
