Matinas BioPharma Holdings, Inc. (the “Company”) issued a press release announcing that the independent Data and Safety Monitoring Board (“DSMB”) of the EnACT study (Encochleated Oral Amphotericin for Cryptococcal Meningitis Trial) has completed a pre-specified review of the first cohort and unanimously recommended progression to the second cohort of patients. A copy of the press release is furnished as Exhibit 99.01 hereto and incorporated herein by reference.

The information in this Item 7.01 and Exhibit 99.1 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 (the “Securities Act”), or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.

On October 19, 2020, the Company announced that the independent DSMB of the EnACT study (Encochleated Oral Amphotericin for Cryptococcal Meningitis Trial) has completed a pre-specified review of the first cohort and unanimously recommended progression to the second cohort of patients. Enrollment in this next randomized EnACT cohort, with 40 active-treatment patients, is expected to begin shortly, with the next DSMB evaluation of safety and efficacy data anticipated to occur in the middle of 2021.

EnACT is a Phase 2 prospective, randomized, open-label, sequential cohort study, financially supported by the National Institutes of Health (NIH), evaluating the safety, tolerability and efficacy of MAT2203 in approximately 100 HIV-infected patients with cryptococcal meningitis. MAT2203 utilizes the Company’s LNC platform delivery technology to orally deliver the traditionally IV-only fungicidal drug, amphotericin B.

The induction period for all patients in each cohort of EnACT is 14 days, followed by an additional 4 weeks of treatment with MAT2203 for all patients during a maintenance period. In total, the trial includes four cohorts of patients, with each cohort increasing the treatment duration of MAT2203 vs. IV amphotericin B. The first cohort received IV amphotericin B for the first five days of the induction period, followed by nine days of oral administration of MAT2203. The second cohort of 40 actively treated patients will receive IV amphotericin B for the first two days of the induction period, followed by twelve days of oral administration of MAT2203. The primary efficacy endpoint will be measured at Day 14, the last day of the induction period, and will include a measure of reduction in fungal count in the cerebral spinal fluid. A control arm, which includes standard of care IV amphotericin B, is included with each cohort. An independent DSMB oversees the safety of the study and reviews all data from each cohort for safety and efficacy and makes a recommendation to proceed to the next cohort of patients.
