Highlights • Interim data from first two patients in National Institutes of Health (NIH) conducted Phase 2a study of MAT2203 for the treatment of refractory mucocutaneous candidiasis infection • Two out of two patients met the primary endpoint in achieving ≥ 50% clinical response • Patients reported meaningful Quality of Life improvements • Objective evidence of effect were also observed, decreased severity of lesions, decreased quantitative fungal cultures. • No serious adverse events reported to date during the course of the study • MAT2203 was well tolerated with majority of adverse events observed to date being mild in severity and unrelated to MAT2203 • Both patients elected to enroll in the long - term extension study 3

 

 

Background • MAT2203: Novel encochleated formulation of a proven molecule, amphotericin B, a broad spectrum fungicidal agent - Novel oral delivery through nanoparticle formulation - Ability to convert an IV - only administered drug into an oral formulation - Early evidence of better tolerability with lower toxicity • Product profile fits well with difficult to evaluate and treat patient populations seen at the NIH - Patients require long term therapy due to chronic drug resistant fungal infections - MAT2203 offers convenient oral dosing of amphotericin B with the favorable safety profile needed for chronic therapy • Interim data from first two patients in NIH - conducted Phase 2a study of MAT2203 for the treatment of refractory mucocutaneous candidiasis infection • Establishes POC in nonlethal fungal infections in immunocompromised patients 4

 

 

Collaboration with NIH • Collaboration with NIH began with IND enabling studies • NIH is conducting the study • Advanced Phase 2a study with enrollment and dosing of first two patients • Study subjects chosen because of inherent impaired immuno - compensation, long term fungal infection of over 20 years and anti - fungal drug resistence except for amphotericin B • Edmund C. Tramont, MD, MACP, FIDSA - Co - Investigator of the study - National Institutes of Health, National Institute Allergy and Infectious Diseases - Associate Director for Special Projects, DCR/NIAID/NIH - Former Director, Division of AIDS, NIAID/NIH, Consultant to the Surgeon General in Infectious Diseases 5

 

 

Key Unmet Need Drivers 1. Increasing resistance to presently available antifungal therapies 2. Increasing numbers of immunocompromised hosts/patients 6

 

 

Amphotericin B Value/Strengths of Amphotericin B • Amphotericin B is the most broad spectrum fungicidal agent • Gold standard of therapy for the treatment of all fungal infections • Little to no clinical resistance has developed in over 60 years of use Limitations of Amphotericin B • IV dosing • Toxicity (renal, hypokalemia) is observed at the same dose level required for efficacy and increases with therapy over 1 - 2 weeks 7

 

 

Refractory Mucocutaneous Candidiasis Infection in Hereditary Immunocompromised Patients • Autosomal Dominant Hyper IgE Syndrome (HIES or Job’s Syndrome) - HIES is a hereditary condition resulting in a weak immune system, involving STAT3 gene and resulting in IL - 17 and IL - 18 signaling deficiencies - Typical features: eczema, high serum IgE levels and characteristic facial and skeletal abnormalities - Highly susceptible to micro - organisms that colonize human bodies but seldom cause disease in healthy people , Candida (mucocutaneous candidiasis), recurrent Staphylococcus aureus and Pseudomonas infections • Refractory Mucocutaneous Candidiasis Infection - Persistent superficial infections of the skin, mucous membranes, and nails with Candida organisms - Limited treatment options due to resistance and toxicity associated with prolonged use of currently approved anti - fungal therapies - Inadequate response to standard amphotericin B “swish - and - swallow” 8 Because of the very weak immune system, the anti - infective medication has to do almost the entire job on its own, with little help from the patients immune system

MAT2203 Phase 2a Study Protocol • Open - label, dose - titration trial of MAT2203 (oral cochleate amphotericin B) • Evaluate up to 16 patients to determine the efficacy, safety, tolerability and pharmacokinetics of MAT2203 in treating recurring or refractory mucocutaneous candidiasis infections • Subjects: hereditary immuno - deficiency patients with refractory candida mucocutaneous infections – most patients will be infected with azole resistant candida • Study Design: 10 Initial MAT2203 dose 200 mg/day, for 14 days Significant Clinical Response Limited Clinical Response Extended treatment to 28 days Titrate dose to 400 mg/day or further titrated to 800 mg/day for an additional 14 days at each higher dose – total treatment up to 56 days

 

 

Interim Data - Safety Highlights • Oral treatment with MAT2203 for up to 54 days was well tolerated • No serious adverse events reported • Reported adverse events were mostly mild in severity and unrelated to MAT2203 • No signs of nephrotoxicity, hypokalemia or hepatoxicity (measured by ALT and AST) 11

Interim Data - Efficacy Highlights • Two out of two patients achieved ≥ 50% subjective and objective clinical response - Both patients reported improved quality of life, e.g. able to eat a greater variety of foods, including those that are acidic and spicy • Two out of two patients achieved objective responses, verifying the subjective responses - Both patients experienced improvements in fungal culture response - Both patients mucocutaneous lesions improved: less inflammation, less pain on scrapping of the lesions for culture 15

Interim Data Study Conclusion • Two patients with AD - HIES or Job’s Syndrome with long - standing azole resistant mucocutaneous candidiasis responded clinically to oral treatment with MAT2203 • Oral treatment with MAT2203 for up to 54 days was well tolerated - Reported adverse events were mostly mild in severity and unrelated to MAT2203 - There were no serious adverse events reported • There were no signs of nephrotoxicity, hypokalemia or hepatoxicity after oral dosing for 54 days in Patient 01 and 40 days in Patient 02 • Both patients elected to enroll in the long - term extension study 19

 

 

Clinical Unmet Needs • Increasing resistance to presently available antifungal therapies • Increasing number of patients being rendered immunocompromised by advancements in medicine - NIH is in the vanguard of studying immunocompromised patients, the number of which is expected to increase due to the growing use of immuno - compromising drugs for transplants, cancer chemotherapies, and autoimmune diseases • Since antifungal therapy usually requires prolonged administration, there is a need for an oral, safe and effective antifungal therapy, that can be dosed conveniently over time • An effective and non - toxic oral amphotericin B could address these unmet needs 20

 

 

MAT2203 Development Program and Next Steps • Company takeaways - Response results likely predictive of study outcome - Safe long - term use supports development strategy towards preventative treatment • Second Phase 2 – next data readout: vulvovaginal candidiasis (VVC) – key objectives - With oral delivery, demonstrate safety and efficacy comparable to fluconazole (gold standard for the treatment of primary/uncomplicated VVC) - Expecting data from VVC before end of June • Interim results from this study are significant steps toward: - Establishing POC for the MAT2203 product - Providing validation of technology platform - Strengthening our position to also evaluate range of fungal infections, e.g. aspergillosis, coccidiomycosis, cryptococcosis , histoplasmosis, blastomycosis , molds - Strengthening our position to impact and change treatment paradigms 21

 

 

Prevention of Invasive Fungal Infections (IFI) Represents a Significant Market Opportunity 22

 

 

MAT2203: IFI Prevention is a Significant Value Driver • QIPD and Fast Track designations granted by FDA for MAT2203 - “Prevention of invasive fungal infections (IFI) due to immunosuppressive therapy” • Represents significant unmet clinical need - very few antifungals are approved for the preventative use in patients on immunosuppressive therapy • Amphotericin B (currently only available for IV infusion) is not liver - metabolized and has very few drug - drug interactions with cancer/transplant therapies • Encochleated amphotericin B (MAT2203) is designed to significantly reduce toxicities associated with the amphotericin B molecule, while making the compound absorbable in the body by convenient oral administration 23
