Advisors to Consider Peanut Allergy Treatment
The FDA Allergenic Products Advisory Committee meets 9/13 to consider Aimmune Therapeutics’ BLA for Palforzia (peanut allergen powder) with a proposed indication to reduce the incidence and severity of allergic reactions, including anaphylaxis after accidental exposure to peanut in patients aged 4 through 17 years with a confirmed diagnosis of peanut allergy. In a briefing paper released in advance of the meeting, agency medical reviewers say the drug met its efficacy endpoints in clinical trials, but there were some safety issues.
The reviewers say treatment with Palforzia resulted in an increased risk of allergic reactions, some of which resulted in increased epinephrine use compared to the trial group given a placebo. There also were more trial subjects in the Palforzia arm who discontinued treatment due to side effects than in the placebo arm.
FDA will be asking the committee whether the efficacy and safety data support licensure of Palforzia as a treatment to reduce the incidence and severity of allergic reactions, including anaphylaxis after accidental exposure to peanut in patients aged 4 through 17 with a confirmed diagnosis of peanut allergy.
