AboutMatinas BioPharma

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

Preclinicaland clinical data have demonstrated that this novel technology can provide solutions to many of the complex challenges in achieving safeand effective intracellular delivery, for both small molecules and larger, more complex molecules, such as mRNA, DNA plasmids, antisenseoligonucleotides 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 deliveryvehicle and an important improvement over both lipid nanoparticles and viral vectors.

MAT2203is an oral, LNC formulation of the highly effective, but also highly toxic, antifungal medicine amphotericin B, primarily used as a first-linetreatment for invasive fungal infections. MAT2203 is currently in a Phase 2 open-label, sequential cohort study (EnACT) in HIV-infectedpatients with cryptococcal meningitis. Enrollment in Cohort 3 of EnACT commenced following unanimous approval from the Data and SafetyMonitoring Board (DSMB) and is now fully enrolled. DSMB evaluation of Cohort 3 data and potential cohort progression is expected priorto the end of 2021.

MAT2501is an oral, LNC formulation of the broad-spectrum aminoglycoside antibiotic amikacin, primarily used to treat chronic and acute bacterialinfections. With the support of the Cystic Fibrosis Foundation, MAT2501 is currently undergoing important preclinical studies and commenceda Phase 1 human clinical trial in the fourth quarter of 2021. MAT2501 would be the first and only oral aminoglycoside, and is being positionedwith an initial indication for the treatment of nontuberculous mycobacterial (NTM) lung disease, including infections in patients withcystic fibrosis.

LYPDISO™,is a prescription-only omega-3 fatty acid-based composition, comprised primarily of EPA and DPA, intended for the treatment of cardiovascularand metabolic conditions. This next-generation omega-3 therapy has been shown in two head-to-head studies to provide effective triglyceride-loweringand significantly higher EPA blood levels than Vascepa^®. The Company has initiated a process to identity and potentiallysecure a partner to continue development of LYPDISO.
