Big few weeks with #PENFAST making it to Hollywood 🎥… but this might be even better 👇 The @ProspectorTrial #PROSPECTOR1 Trial led by @Austin_Health and @TheDohertyInst is now published in @NEJMEvidence 🔥 ➡️ evidence.nejm.org/doi/full/1… ✅ First double-blind, placebo-controlled trial in #drugallergy ✅ Pilot feasibility RCT (n=120) ✅ Single-dose vs 5-day amoxicillin challenge in delayed/unknown #penicillinallergy It was feasible and safe — and showed a 6.7% increase in immune-mediated reactions in the (multi-dose) arm. Nice Editorial: ➡️ evidence.nejm.org/doi/full/1… We’re getting closer to answering the question… Is one dose ever enough? 👀 #PROSPECTOR2 now recruiting (doi: 10.1136/bmjopen-2024-094712)

Feasibility Trial of Prolonged versus Single-Dose Challenge in Penicillin Allergy

We aimed to evaluate the feasibility of conducting a multicenter, double-blind, placebo-controlled trial of prolonged (i.e., multidose) compared with single-dose amoxicillin challenge in patients w...
