neffy clinical program supports NDA
filed and accepted by FDA NDA submission accepted by FDA in Q4 2022; Target PDUFA action date anticipated in mid-2023 FDA confirmed three primary registration studies required for neffy approval EPI-17: Self-administration in Type I allergy patients
(n=42) EPI-15: Single dose and twice dosing in healthy volunteers (n=42) EPI-16: Nasal challenge in allergic rhinitis patients (n=36) neffy meets the endpoints discussed with FDA in completed clinical studies* Criteria (Cmax, tmax, early partial
AUCs) is comparability to epinephrine injection products (bracketed by approved products) IM needle & syringe is the gold standard and reference-listed drug Primary outcomes for all trials: PK (bioavailability) and PD (SBP, HR) EPI-10 pediatric
trial interim data included in NDA submission, FDA requested Data in subjects aged 4 to 18 (single-arm, non-comparative expected in 2022) to support pediatric labeling *Pending review by the FDA

IV, SC or IM dosing depending on technique All approved products have indistinguishable clinical effect and time to observed clinical benefit: ~90% resolution on first dose within the first 5 to 15 minutes observed for both IM and autoinjectors in
literature and practice All products approved based on only PK, despite significant PK differences - (i.e. not bioequivalent to each other) PD is supportive *Baseline corrected

neffy market exclusivity potential
until at least 2038 Issued composition of matter patent (US10,576,156) on Intravail + epinephrine provides foundational exclusivity blocking any generic products. Method of treatment patents (US11,173,209; US11,191,838) block other alkyl
glycosides. Issued method of treatment patent (US10,682,414) blocks any intranasal epinephrine product using a different technology using a low dose (<2.5 mg) PCT patent granted in Europe (EP19751807), UK (GB2583051), Japan (JP6941224), Australia
(AUS2019217643) and Korea (10-2375232) with same composition of matter and method of treatment claims as the US Extensive studies in the lab and clinic completed to develop a proprietary product with expected NCE-like exclusivity EXPECTED LAUNCH

Commercial Opportunity and
MULTIPLE LEVERS OF CURRENT MARKET
GROWTH Significant existing US market opportunity for neffy penetration CURRENT ~$1 BILLION1 ANNUAL EPINEPHRINE MARKET IS THE IMMEDIATE OPPORTUNITY 1 SEC filings, IQVIA data and ARS payer research data on file 2 ARS market research data on file (n =
75 physicians, n = 150 patients), 3 IQVIA extended unit data ~3.3M Patients have injectable today (~10 million devices)3 ~16M diagnosed patients with severe type I allergic reactions (claims data) Consistent market growth +5% y/y in the last ~15
years Promotional responsiveness +31% historic lift from Mylan No meaningful promotion today More devices per patient Potential for twice as many neffy devices annually vs. injectables ~2.5M Former patients discontinued or did not fill Rx in last 3
years Up to 40M total type I allergy patients (epidemiology)
Physicians supportive of adopting
neffy into practice Would prescribe neffy if their patients asked for it 100% 10 = MAJOR ADVANCE / 1 = NOT AN ADVANCE AT ALL 8.5 out of 10 rating viewed as a major advance in therapy n = 75 Physicians No difference in uptake of neffy by physician
neffy addresses the unmet need and
is better aligned with what healthcare providers, patients and parents want 65% to 72% OF THE TIME, PEOPLE WHO USE AN OTC WOULD USE neffy FIRST 69% OF PEOPLE WOULD USE neffy SOONER THAN CURRENT AUTOINJECTOR OF NON-FILLING
PATIENTS STATED THEY WOULD ASK THEIR PHYSICIAN ABOUT neffy RX 75% n = 150 Current Users OF PATIENTS EXPECTED TO SWITCH TO neffy ~80% n = 100 Non-fillers
Caregivers are enthusiastic about
neffy and its benefits Source: ARS Consumer Quant Research, 2022 Q29/68. How long would you estimate it took from the time the symptoms started before you used your device? Q75. The last time you/your child had an allergic reaction, you said you
used your/your child's device within XX minutes. If you had had this epinephrine nasal spray device instead of your/your child's current device, how quickly do you believe you would have used it after your/your child's initial
symptoms of the reaction? Q76. On a scale of 1-10, how much impact would each of the following have to motivate you to use this epinephrine nasal spray device sooner than your/your child's current device? Q77. On a scale of 1-10, how likely
would each of the following be if you were to have this new epinephrine nasal spray device instead of your/your child's current device? This is fantastic. Much easier than jabbing the thigh. - Father We are talking about someone's
life and lifestyle here. Great improvement. - Mother I don't have a co-pay, but I'd get this for my daughters even if I have to pay $50. - Mother I want this. Is it available yet? Let me know when it is, I will literally call
the doctor from my car. - Mother " " " "
