Risk of IFI in Patients with Hematologic Malignancy is Increasing and Mortality Rates are High • Increased risk is attributed to host defense impairment due to intensive cytotoxic chemotherapies, HSCT, ablative radiation therapy, use of corticosteroids, cyclosporine, and new immunosuppressive agents. • In a cohort of 11,802 Italian patients with hematologic malignancy there were 538 (4.6%) proven or probably IFI. Sixty - nine percent occurred in patients with AML. • IFI - attributable mortality rate was 39% 5 64 53 42 33 0 10 20 30 40 50 60 70 Zygomycosis Fusariosis Aspergillosis Candidemia Rate (%) Adapted from Pagano et al. 2006.

Structure of Nanocochleate Formulations 7 Cargo Molecules Intercalate into the Phospholipid Bilayer Interior

 

 

Cochleate - Mediated Delivery into Activated Cells • Cochleates are actively taken up by activated cells such as infected macrophages and virus infected cells, resulting in delivery of cargo molecules directly into the interior of the cell • The normal low concentration of calcium within the cytoplasm of cells causes cochleates to unroll and release their contents • The presence of calcium outside the macrophage prevents the cochleate from opening • Once inside the macrophage, the low level of calcium, (1,000 – 10,000 times lower) causes the cochleate to open, releasing the drug. The drug tends to stay within the cell, and defuses out slowly 8 Low Calcium Environment 1 2 Cochleate opens up under low calcium environment and releases anti - infective into macrophage cell 3 Macrophage travels to infected tissues and delivers anti - infective Macrophage Cell Cochleate enters macrophage cell High Calcium Environment

 

 

Cochleates Can Change the Pharmacokinetics and Biodistribution of Drugs 9 Macrophage Free Drug • Free drug in the extracellular milieu must cross the cell membrane in order to be effective against intracellular microorganisms. • High plasma and interstitial drug levels are needed. • A relatively low percentage of circulating drug enters the cell. • Drugs with these properties have difficulty treating intracellular infections. • High circulating drug levels can result in nonspecific toxicity. Drug - Cochleate Macrophage Free Drug Cochleate Model of Drug Delivery - The “Trojan Horse” Hypothesis Traditional Model of Drug Delivery • High calcium concentrations in gastrointestinal secretions, serum and interstitial fluid stabilize the drug - cochleate crystal • Drug cochleates enter the circulatory system, diffuse into tissues and/or are taken up by “activated” and/or infected cells • Intracellular levels of drug - cochleates increase and reach high levels • The low intracellular calcium concentration causes the drug - cochleates to open, releasing their cargo, the cochleates • Lower plasma levels are required to reach efficacious intracellular drug concentrations • These lower plasma levels may result in less systemic toxicity

MAT2203 Product Profile 12 Fungicidal; Broad Spectrum Few Drug – Drug Interactions Cochleate Benefits • Amphotericin B is perhaps the broadest spectrum antifungal agent • Amphotericin is not metabolized through typical liver pathways and does not experience the drug - drug interactions typically seen with many triazole antifungal agents; Allows for broader use with complicated oncology regimens • Cochleates are designed to provide oral bioavailability , dramatic reduction in toxicity and targeted delivery

 

 

13 Combined 12 - Year Exclusivity QIDP and Fast Track Designations to Date: • Treatment of Invasive Candidiasis • Treatment of Aspergillus • Prevention of IFI due to immunosuppressive therapy Orphan Drug Status: 7 Years Exclusivity QIDP: 5 Years Exclusivity US Regulatory Environment Provides Solid Market Exclusivity Opportunity Through GAIN and Orphan - Drug Acts Potential for Orphan Drug Designations

 

 

MAT2203 – IFI Prophylaxis is a Significant Value Driver • On September 7, 2016, MTNB announced FDA grant of QIPD and Fast Track designations for MAT2203 for: “Prevention of invasive fungal infections (IFI) due to immunosuppressive therapy” • Due to significant drug - drug interaction and lack of oral delivery forms, very few antifungals are approved for the prophylactic use in patients on immunosuppressive therapy – a significant unmet clinical need remains • Amphotericin B (currently only available for intravenous infusion), the antifungal compound in MAT2203, has very few drug - drug interactions with cancer/transplant therapies • The lipid - crystal nano - particle delivery system for MAT9001 significantly reduces toxicities associated with amphotericin B, while making the compound absorbable in the body by convenient oral administration IFI Prophylaxis: • Broad population: US prevalence of leukemia is approximately 340,000 (111,000 acute forms of leukemia) plus ~51,000 transplants annually (20,000 stem cell + 31,000 organ transplants) • Treatment period extended over the entire high - risk episode: typically 6 - 14 weeks, depending on patient type • Significant reduction of morbidity and mortality in target patient population • Significant savings in cost of treatment of IFI in high cost ICU or similar hospital environment, justifying economics of prevention IFI Treatment: • Limited population: annually 46,000 Candidiasis + 5,000 Aspergillosis cases in US (>90% of IFI) • Treatment period limited: typically 1 - 3 weeks, depending on patient condition and improvement • Significant morbidity and mortality rate in patients with IFI; mortality risk 40% - 90%, depending on fungal species • Significant cost of treatment for IFI, adding ~$50,000 per IFI case in 2016 dollars 14
