The FDA accepted for review the New Drug Application (NDA) for neffy for the emergency treatment of allergic reactions (type I) including anaphylaxis in adults and children ≥30 kg (66 lbs). If approved by the FDA, neffy would be the first non-injectable treatment available to patients with allergic reactions (type I) including anaphylaxis. Prescription Drug User Fee Act (PDUFA) target action date is in mid-2023 [8].

Nov 20ARS announces acceptance of MAA submission by EMA. The MAA submission includes data from multiple clinical studies showing that 1 mg of Neffy achieves epinephrine exposures that are similar to a 0.3 mg epinephrine IM injection, with rapid absorption and clinical response based on surrogate endpoints. A dosage strength of 0.65 mg is under development for children weighing between 15kg and 30kg and is expected to be filed shortly after the initial approval [3].

Trial or other data

Oct 22The NDA submission to the FDA is based on data from four primary registration studies supporting that a 2 mg intranasal dose of neffy met all clinical endpoints recommended by regulators and that its pharmacokinetics were within the range of approved epinephrine injection products. These data included studies in adults, with self-administration and caregiver administration, as well as in children with Type I allergies ≥30 kg (66 lbs). In addition, neffy has been well-tolerated to date with more than 500 individuals receiving at least one dose, and many with repeat administration. The majority of adverse events in clinical trials were mild in nature without any meaningful nasal irritation or pain [8].
Sep 21The company anticipated 60% of epinephrine pen users will switch to Neffy immediately and 80% within two years [4].
Aug 21PI trial to evaluate the pharmacokinetics of epinephrine intranasal spray in patients with upper respiratory tract infections starts recruiting (NCT04930900). The two-treatment, open-label, sequential, crossover trial intends to enrol 12 patients aged 18-55 years in Australia. Completion of primary outcome data expected Oct 2021 [6].
Jun 19ARS announce topline results from EPI-04 study (n=36). Study demonstrates intranasal adrenaline spray has a similar pharmacokinetic profile to IM adrenaline in patients with allergic rhinitis, however, the former showed a faster time to peak exposure [2].
