HCPLive Five – Allergy Updates at AAAAI 2025
Counting down the most impactful news at major medical meetings, it’s the HCPLive Five! This episode focuses on 5 key allergy updates from the 2025 American Academy of Allergy, Asthma, and Immunology (AAAAI) annual meeting.
Thousands of allergy experts gathered at this year’s 2025 Academy of Allergy, Asthma, & Immunology (AAAAI) annual meeting in San Diego to connect with colleagues, explore late-breaking data, and attend hundreds of sessions.
As a part of our on-site coverage, The HCPLive Allergy Team reported live from San Diego, conducting dozens of interviews and covering late-breaking research. In this iteration of the HCPLive Five, the team highlighted standout video interviews, covering topics such as insect allergy testing, chronic rhinosinusitis, omalizumab for food allergies, oral immunotherapy with autoclaved peanuts, and the WAYPOINT phase 3 trial assessing tezepelumab for nasal polyp management.
When to Test for Insect Sting Allergies, with David Golden, MD
David Golden, MD, from Johns Hopkins University, discussed the pitfalls of over-testing for insect sting allergies. He emphasized that a positive test does not confirm an allergy, as many people with positive results experience no reaction to stings.
Testing should be reserved for patients with anaphylactic reactions, as unnecessary testing can lead to undue worry and even disqualify individuals from opportunities like military service. Unlike peanut allergies, insect allergy tests do not predict reaction severity, making it crucial for clinicians to avoid misinterpreting strong test results as indicators of severe allergy risk.
Kent Lam, MD, from Eastern Virginia Medical School at Old Dominion University, discussed when allergists should refer patients with chronic rhinosinusitis for endoscopic sinus surgery; surgery is recommended when symptoms persist despite treatment with topical steroids, saline irrigation, or antibiotics.
The procedure aims to improve sinus drainage and ventilation rather than remove tissue. Lam emphasized setting patient expectations regarding risks such as bleeding, scarring, and symptom persistence.
Omalizumab Performs Better Than Oral Immunotherapy for Food Allergy, with Robert Wood, MD
Robert Wood, MD, from Johns Hopkins Medicine, discussed the OUtMATCH trial comparing omalizumab and oral immunotherapy (OIT) for food allergies. The study found omalizumab superior in the intent-to-treat analysis (36% vs 19%; P = .031), but per-protocol analysis—excluding dropouts—showed similar effectiveness (P = .66).
OIT had a high dropout rate due to side effects, while omalizumab was well tolerated. Wood emphasized the need for individualized treatment, as OIT may offer long-term immune changes, but omalizumab provides a safer alternative with fewer side effects.
A study found that peanut-allergic patients tolerated oral immunotherapy better with autoclaved peanuts than with blanched peanuts. Casey Cohen, PhD, from McGill University, explained that autoclaving—using high temperature and pressure—reduces peanut-specific immunoglobulin binding, resulting in fewer severe reactions.
In a double-blind trial of 10 participants, the median tolerated dose was significantly higher for autoclaved peanuts (300 mg vs. 9 mg). No participants required epinephrine for autoclaved peanuts, whereas all were for blanched peanuts.
Tezepelumab Lowers Nasal Polyp Severity in CRSwNP During Phase 3 WAYPOINT, with Joseph Han, MD
The phase 3 WAYPOINT trial demonstrated that tezepelumab significantly reduced nasal polyp severity in patients with severe chronic rhinosinusitis with nasal polyps (CRSwNP), lowering the need for surgery by 92%. Tezepelumab significantly improved nasal congestion, sense of smell, and overall symptom scores at 52 weeks.
Investigator Joseph Han, MD, from Eastern Virginia Medical School, highlighted the near elimination of surgery in the treatment group. These findings support tezepelumab as a promising treatment option for CRSwNP, reducing reliance on systemic steroids and surgical intervention.
