neffy Designed for Ease of Use and Easy Carry For epinephrine to be effective, patients must: neffy has a simple place and press administration (no hold time) 100% of adults and children able to use neffy successfully without any training Relative Size of neffy two pack Compared to iPhone 15 and EpiPen Regularly have their device on hand Not hesitate to dose immediately after symptom onset Have a second device on hand if needed (~10% of cases) Administer the device as intended Case holds two neffy 2mg devices 6” 5.8” 3.1”
Development Program Centers on Pharmacology Studies Efficacy studies not ethical / feasible in severe Type I allergy patients neffy clinical studies developed in agreement with FDA and EMA to allow reference to historic efficacy and safety data of epinephrine injection Bracketed pharmacokinetic (PK) exposures Comparable pharmacodynamic (PD) responses > 1,200 administrations of neffy in > 700 subjects Primary Studies (2 mg dose) Patient Population EPI 15 Adult: Healthy volunteer (HCP administration) – single and repeat dosing EPI 16 Adult: Type 1 allergy patients (NAC induced rhinitis) – single dosing EPI 17 Adult: Type 1 allergy patients (self-administration) – single dosing EPI 18 Adult: Type 1 allergy patients (NAC induced rhinitis) – repeat dosing EPI 10 Pediatric: Type 1 allergy patients: ≥ 30kg (NDA), 15 ≤ 30kg (sNDA) – single dosing
Registrational studies demonstrate comparability on both PD surrogates for efficacy and PK with neffy Safety Data 2 mg neffy met all clinical endpoints PD surrogates for efficacy comparable to approved products (SBP/HR approved injection products) Rapid and significant response on PD surrogates for efficacy observed even 1 minute after dosing PK bracketed by approved products (exposures IM/SC for efficacy, < EpiPen for safety) Repeat doses (including during rhinitis) within range of approved injection products Adverse events generally mild in nature with no meaningful nasal irritation or pain up to 4 mg dose Most common adverse events (>5%) were mild nasal discomfort (9.7%) and mild headache (6%), with no correlation of nasal discomfort to pain or irritation Mean VAS pain scores between 5 to 8 out of 100 No irritation based on formal assessment No serious adverse events in any clinical study No risk of needle-related injuries or blood vessel injections with neffy PD and PK Data Response to FDA submitted on April 2, 2024 followed by up to 6-month FDA review

Multiple Attributes Contribute to neffy’s Potential Best-in-Class Epinephrine Product Profile Will patients use it? Benign safety profile – mild nasal discomfort and headache Palatable – no meaningful pain/irritation, no taste/smell Small – fits in pocket Easy to use – 100% of adults and children can use without training (even passerby’s); ability to dose not obstructed by anaphylaxis symptoms Is it safe? Benign safety profile – mild nasal discomfort (9.7%) and mild headache (6%) No risk of injury (no needle) and minimal risk of overdose even with population variability (high bioavailability, low dose) No side effects (GI, vomiting, erythema) that could confound clinical monitoring and treatment Does it work? PK/PD response shows onset within 1 minute after dosing Rapid efficacy profile in OFC anaphylaxis (100% response rate in first 15 min), as well as treatment-resistant urticaria Predictable dose-proportional PK/PD profile within range of approved injection products even under real-world co-morbidities (e.g. rhinitis) Only anaphylaxis symptom that may alter PK/dosing is rhinitis, and for neffy, no negative impact on PK/PD 99.999% reliable sprayer device – tens of millions of units sold annually in US
neffy: the first needle-free way to administer epinephrine Rapid, reliable delivery Small and easy to carry Place and Press administration Well-tolerated in extensive trials AVOIDS ALL NEEDLE-RELATED ADVERSE EVENTS
Appendix
EPI-18 Repeat Dose NAC Study Design Rationale: Study designed together with FDA to generate data on neffy’s PK/PD profile if NAC-like conditions occurred during the 10% of anaphylaxis events that require a second dose Comparator: FDA explicitly requested ARS include 0.3 mg intramuscular (IM) injection via manual syringe as the reference, and not an autoinjector, as IM is the basis for efficacy of all products Treatments: repeat doses of 2 mg neffy (normal R/L, NAC R/L – opposite nostril, NAC R/R – same nostril), repeat doses of 0.3 mg IM injection (rhinitis and normal) Population: 43 patients with seasonal allergic rhinitis who test positive with a Total Nasal Symptom Score (TNSS) of ≥5 out of 12 and a congestion score of ≥2 out of 3 during the screening NAC Spray antigen directly onto nasal mucosa to induce NAC 1st epinephrine dose within 15 min of NAC induction at peak effect t = 0 t = -15 min 2nd epinephrine dose given 10 min after 1st dose per FDA labeling t = 10 min PD response (SBP, HR) measured from baseline to 120 min t = 240 min PK (plasma epinephrine) measured from baseline to 240 min Repeat Dose NAC PK/PD Methodology (5 treatment periods, randomized, crossover)
PD response (SBP) with repeat doses of neffy with or without NAC greater or similar to repeat doses of injection Dosing 10 min apart
PD response (HR) with repeat doses of neffy with or without NAC greater or similar to repeat doses of injection Dosing 10 min apart
Exposures with repeat doses of neffy with or without NAC greater or similar to repeat doses of injection Dosing 10 min apart
Exposures with repeat doses of neffy with or without NAC greater or similar to repeat doses of injection (first 60 min) Dosing 10 min apart
