## What Matinas Biopharma Holdings does

Matinas BioPharma Holdings, Inc. is a clinical-stage biopharmaceutical company focused on therapies built on its lipid nanocrystal (LNC) platform. Its lead product candidate, MAT2203, is an oral form of amphotericin B, a highly potent antifungal drug that the company says has been made oral, safe and well-tolerated for prolonged administration in patients with life-threatening invasive fungal infections. After the EnACT Phase 2 trial in cryptococcal meningitis, MAT2203 was positioned for a single Phase 3 registration trial, the ORALTO trial, in support of a New Drug Application for invasive aspergillosis in patients with limited treatment options. Following an 80% reduction in workforce, the company paused further clinical development of MAT2203 and continues to seek one or more development or commercialization partners. The company says it will require either a partnership transaction or additional capital before commencing the ORALTO trial. It keeps the MAT2203 Investigational New Drug application active with the FDA, maintains an Expanded/Compassionate Use Access Program, and maintains its obligations under a license agreement with Rutgers University. It has also paused internal development of LNC programs in oncology and inflammatory diseases while it evaluates strategic alternatives for them.

| Product or program | What it is | Stage |
|---|---|---|
| MAT2203 | Oral amphotericin B antifungal for invasive fungal infections | Phase 2 completed; ORALTO Phase 3 awaits partnership or capital |
| LNC platform | Lipid nanocrystal delivery technology for small molecules and oligonucleotides | Internal pipeline paused |
