Antibiotic Allergy clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Repertoire and Properties of Anti-drug Antibodies Involved in Immediate Hypersensitivity in the Operating Room

MEDIREP

Start date: April 12, 2023
Phase: N/A
Study type: Interventional

Acute per-anesthetic hypersensitivity reaction (HSA-PA) is a rapidly occurring systemic reaction following injection of a drug during anesthesia (mortality between 3 and 9%). The substances responsible for these reactions in France are curare in 60% of cases, followed by antibiotics. The main mechanism mentioned is an immediate systemic hypersensitivity immune reaction mediated by IgE antibodies (anaphylaxis). NeuroMuscular Blocking Agents (NMBA; curare) relax skeletal muscles to facilitate surgeries and permit intubation, but lead to adverse reactions: (a) severe hypersensitivity reactions (anaphylaxis) thought to rely on pre-existing anti-NMBA antibodies; (b) complications due to postoperative residual curarization. Identification of patients at risk remains suboptimal due to the lack of adequate tools to detect anti-NMBA antibodies. A capturing agent exists for only one out of the four most used NMBAs, allowing reversal of profound curarization. Case reports suggested that it might also ameliorate an ongoing anaphylaxis due to that NMBA. Based on strong preliminary results, our study proposes to characterize anti-drugs antibody repertoires in patients with various NMBA or antibiotics-anaphylaxis, describe activation pathways leading to anaphylaxis, develop and validate diagnostic and therapeutic molecules to ameliorate patient screening, NMBA-anaphylaxis and reverse profound neuromuscular block.
