Protocol of Reintroduction of Beta-lactams in Children at Low Risk of Anaphylaxis.

Study Purpose

The purpose of this study is to establish the rationale for the practice of performing an oral reintroduction test without previous skin tests in children at low risk of IgE-mediated reaction or drug-induced toxidermia, and to confirm the criteria for a drug reintroduction test could be performed without previous skin tests, without subsequent risk of reaction for the child. The primary endpoint will be the risk of a severe IgE-mediated or delayed hypersensitivity reaction in children who received beta-lactam drug reintroduction protocol prior to skin testing.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages N/A - 16 Years

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
