FDA's Surprising Decision: The Neffy Epinephrine Nasal Spray Rejection and What It Means for Allergy Treatment

In a surprising turn of events, the FDA has rejected the approval of Neffy, an epinephrine nasal spray that was poised to offer a needle-free alternative to epinephrine autoinjectors, such as EpiPens.

The FDA's decision has raised eyebrows as it diverges from the typical approval process, despite the agency's advisory committee having recommended Neffy's approval in May. 

Now, the FDA is requesting additional research on Neffy, prompting a response from its manufacturer, ARS Pharmaceuticals.

ARS Pharmaceuticals expressed its astonishment at the FDA's decision and has announced its intention to appeal the agency's request for more data.

Epinephrine, a long-standing and highly effective treatment for severe allergic reactions, has been in use since 1901. 

Its reliability in reversing anaphylaxis, a life-threatening condition, is well-established.

While epinephrine is undeniably effective, its administration through injection presents a challenge for those with needle phobias, highlighting the need for needle-free alternatives.

Advocates have long been pushing for needle-free alternatives to make allergy treatment more accessible and less daunting.

One of the key concerns during the advisory committee meeting was the lack of comprehensive clinical data, especially in patients experiencing anaphylaxis.

Despite reservations about the data gap, the advisory panel voted in favor of Neffy for both adult (16-6) and child (17-5) use.
