Matinas BioPharma Holdings, Inc. (the "Company") issued a press release announcing positive efficacy and safety data from the first two cohorts of patients in the ongoing Encochleated Oral Amphotericin for Cryptococcal Meningitis Trial ("EnACT") of MAT2203 (oral amphotericin B) for the treatment of cryptococcal meningitis. A copy of the press release is furnished as Exhibit 99. 1 hereto and incorporated herein by reference.

The Company created a presentation which includes the data from EnACT trial (the "Presentation") which it intends to use during a planned conference call on September 13, 2021 and then at various conferences and investor meetings. The Presentation is attached hereto as Exhibit 99.2.

The Company updated its corporate presentation (the "Corporate Presentation") which it intends to use at various conferences and investor meetings. The Corporate Presentation is attached hereto as Exhibit 99.3.

The information in this Item 7.01 and Exhibits 99.1, 99.2 and 99.3 attached hereto shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or otherwise subject to the liabilities of that Section, nor shall such information be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.




Item 8.01. Other Events.

On September 13, 2021, the Company announced positive efficacy and safety data from the first two cohorts of patients in the ongoing Encochleated Oral Amphotericin for Cryptococcal Meningitis Trial (EnACT) of MAT2203 (oral amphotericin B) for the treatment of cryptococcal meningitis, which is being sponsored by the National Institute of Allergy and Infectious Diseases ("NIAID").

The EnACT independent Data and Safety Monitoring Board ("DSMB") recently completed a pre-specified review of available safety and efficacy data from Cohort 2 (stepdown to MAT2203 after two days of IV amphotericin) and unanimously recommended progression to the second half of the study. Enrollment in Cohort 3 of EnACT (the safety lead-in for Cohort 4, which will be an all-oral MAT2203 treatment regimen) has commenced and is expected to complete by the end of 2021.

Topline Results from Cohort 2 of EnACT

Key topline results from Cohort 2 of EnACT include eradication of the fungal infection, survival, and safety, including longer term use of MAT2203 beyond the 2-week induction period.

Potent Early Fungicidal Activity (EFA), Cerebrospinal Fluid (CSF) Sterilization, with No Evidence of Breakthrough Infections During Treatment with MAT2203

? The primary endpoint in EnACT is EFA, a measurement of cerebrospinal fluid

fungal clearance. EFA is a well-validated quantitative measure of the efficacy

of antifungal agents and is a key surrogate marker for survival. EFAs of less

than 0.20 log10 Cryptococcus colony forming units (CFUs) per mL CSF per day

are associated with significantly higher mortality and worse clinical

outcomes1. EFA measured above this threshold is clinically meaningful and

represents robust fungal clearance. In the second cohort of EnACT, the mean

EFA achieved with patients treated with MAT2203 was 0.38 log10 CFU/mL/day,

with 95% confidence intervals (0.30 to 0.46) significantly higher than the

prespecified primary endpoint threshold of >0.20.

  ? All patients treated with MAT2203 who completed the induction phase achieved
    sterile CSF cultures during treatment (either during induction or early
    consolidation phases).

  ? There was no evidence of breakthrough or relapsed cryptococcal infections
    observed in any of the patients during treatment with MAT2203 through 10
    weeks.




Survival



  ? In Cohort 2, overall survival was 95% in 40 patients randomized to receiving
    MAT2203.




Safety



  ? In both Cohorts 1 and 2, MAT2203 showed no evidence of renal toxicity or
    electrolyte abnormalities attributable to MAT2203, no major safety signals,
    and no use-limiting tolerability issues, even with longer-term treatment with
    MAT2203 extended beyond induction into the consolidation phase, from week 2 to
    week 6.

The Company is preparing to engage with the U.S. Food and Drug Administration ("FDA") to review these data as supportive of a potential early approval of MAT2203 as step-down therapy. These data may also set the stage for potential longer-term treatment options, including prophylaxis, for patients dealing with, or at risk for, deadly invasive fungal infections without the toxicities usually associated with IV amphotericin.

The EnAct trial demonstrated that two days of intravenous amphotericin B followed by rapid transition to oral LNC amphotericin B therapy was well tolerated, resulted in excellent CSF clearance of the Cryptococcus yeast, and had a 95% survival to date.
