The Unmet Need 9 Intraductal Microcatheters • Provides alternative to Systemic delivery, which has: - Systemic adverse effects - Limited tumor drug level • ATOS microcatheter technology may: - Increase drug to tumor ratio - Improve efficacy - Reduce toxicity - CAR - T cells may follow lymphatic migration of cancer Topical Endoxifen for Density • No FDA approved treatment • 10 million women (1) • Tamoxifen use minimal Oral Endoxifen for Refractory • Up to 500,000 tamoxifen patients under - treated (too - little E ndoxifen ) (2, 3) • Raising E ndoxifen levels may reduce risk of recurrent or new lesions (1) National Cancer Inst.: Prevalence of Mammographically Dense Breasts in the United States (Retrieved from: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4200066 / ) (2) Breast Care (Basel): Clinical Relevance of CYP2D6 Genetics for Tamoxifen Response in Breast Cancer ( Retrieved from: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2931018 / ) (3) Cancer.net: Hormonal Therapy for Early - Stage Hormone Receptor - Positive Breast Cancer (Retrieved from: https://www.cancer.net/research - and - advocacy/asco - care - and - treatment - recommendations - patients/hormonal - therapy - early - stage - hormone - receptor - positive - breast - cancer )



Endoxifen – Rationale for Development 10 • Develop TWO formulations for two large unmet medical needs: – Topical to reduce density: less than 5% of patients at increased risk of breast cancer will take oral t amoxifen because of actual or perceived side effects (1) – Oral: up to 50% of patients taking tamoxifen are refractory (2) – Tamoxifen Treatment Delay: it takes 50 - 200 days for tamoxifen to have treatment effect • Extensive existing data on Tamoxifen (1) Patient reluctance toward tamoxifen for breast cancer primary prevention, Ann. Surg O n col , 2001 Aug 8(7):580 - 5 (2) Data from Defined Health: SERM Report January 2017



• Low levels of circulating Endoxifen during tamoxifen adjuvant therapy correlate to an increased risk of recurrent or new breast cancers • Identified as an independent risk factor • Known and unknown causes for low endoxifen levels during tamoxifen therapy • Most active tamoxifen metabolite • It may save more lives Why Endoxifen? 11



Endoxifen - Overview 12 • Most active metabolite of tamoxifen • Tamoxifen has been widely studied • Tamoxifen is a pro - drug • Up to 50% of patients can’t make enough E ndoxifen (1) Tamoxifen Endoxifen (1) Breast Care (Basel): Clinical Relevance of CYP2D6 Genetics for Tamoxifen Response in Breast Cancer ( Retrieved from: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2931018 / )

Endoxifen – Phase 1 Clinical Trial 15 • Study started in Q2 2017 in Australia; completed Q3 2017 • Pharmacokinetics; safety and tolerability • Placebo controlled, double - blinded • 48 female volunteers • Oral and topical arms at varying dose levels • Single, 28 day repeat dose



Endoxifen – Preliminary Phase 1 Results 16 All objectives in both topical and o ral arms successfully met: • Safety: no clinically significant safety signals and no clinically significant adverse events. • Tolerability: tolerated at each dose level through out the study. • Pharmacokinetics : • Topical - crossed the skin barrier when applied daily to the breast, as demonstrated by low but measurable Endoxifen blood levels detected in a dose - dependent fashion. • Oral - demonstrated blood levels that have been associated with a therapeutic effect in the adjuvant setting in women with breast cancer.



Oral Endoxifen – Potentially Faster Therapy 17 Atossa Oral Endoxifen May Solve the “Tamoxifen Delay” Endoxifen Source Time to Steady State Oral Tamoxifen (daily) Approx. 50 to 200 days (1) Atossa Oral Endoxifen (daily) 7 days (1) https ://www.ncbi.nlm.nih.gov/pmc/articles/PMC3357105/



Oral Endoxifen 18 Oral Endoxifen may solve the “Tamoxifen Delay” • Low Endoxifen levels in breast cancer patients who take oral tamoxifen correlate with an increased risk of developing new tumors or recurrence • Steady - state of Endoxifen in the serum as a metabolite from daily oral tamoxifen occurs approx. 50 to 200 days from the initiation of dosing (depending on the metabolism capabilities of the patient’s liver) • Steady - state of Endoxifen in the serum derived from Atossa’s oral Endoxifen occurs in seven days Atossa Oral Endoxifen may provide Endoxifen levels weeks or months earlier than Tamoxifen



Single Dose Pharmacokinetics Time, hours Pharmacokinetics Summary – Oral Study 19 Potential Therapeutic Level Time to maximum Endoxifen level is less than 8 hours



Oral Tamoxifen Yields Much Slower Blood Levels of Endoxifen 50 to >200 days to reach endoxifen steady - state levels Reference: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3357105/ The difference is metabolizer status 20 Oral Tamoxifen Pharmacokinetics



Endoxifen / Tamoxifen – Treatment Timeline 29 Days +29 Days This is 25 th percentile on breast cancer growth rate in women 50 - 59, as measured by mammography (1) (1) https://breast - cancer - research.biomedcentral.com/articles/10.1186/bcr2092 Oral Endoxifen Oral Tamoxifen 28



Oral Endoxifen – Refractory Clinical Trial Design 22 Entry Criteria: Pre - menopausal ER + breast cancer patients on tamoxifen Measure Endoxifen Levels >TBD nM Endoxifen Continue on tamoxifen (20 mg/day) ≤TBD nM Endoxifen Add Oral Endoxifen (2 or 4 mg/day)



Endoxifen Regulatory Pathway 23 Program could qualify for designation under the 505(b)(2) status. Advantages: • A single clinical study of safety and efficacy • Limited additional clinical or pre - clinical studies • Multi - year market exclusivity possible



Intraductal Microcatheters 24 • Potential advantages: higher local drug/CAR - T exposure; lower systemic concentrations (lower toxicity) vs systemically delivered agents; potential for lymphatic migration of T - cells • 1 issued and 3 pending patent app’s (US and PCT) for intraductal delivery of drugs and CAR - T • Kite Pharma acquisition by Gilead; Juno acquired by Celgene ; FDA approved Novartis's Kymriah ™ for B - cell Acute Lymphoblastic Leukemia



Intraductal Microcatheters 25 • Phase 2 study for delivery of fulvestrant in patients with DCIS or breast cancer (initiated at Columbia; transferred to Montefiore) • Advantages: potentially higher local drug exposure and lower systemic concentrations vs systemically delivered agents • Fulvestrant is FDA approved for intramuscular administration (AstraZeneca); opportunities with other drugs and biotherapeutics
