The University of Maryland Center of Excellence in Regulatory Science and Innovation (M-CERSI), in collaboration with the Food and Drug Administration (FDA), conducted research and outreach to solicit input from the public, including medical specialists, to better understand the use of certain bulk drug substances nominated for use in compounding by outsourcing facilities under section 503B of the Federal Food, Drug, and Cosmetic Act (the Act). In particular, we were interested in how drugs compounded with these bulk drug substances were used historically, and how they are currently used in clinical practice. The research will assist the FDA in its development of a list of bulk drug substances that outsourcing facilities can use in compounding under section 503B of the Act. Research for each bulk drug substance included a systematic literature review, interviews with medical experts and a survey of healthcare practitioners. Our findings for the nominated substance, carbamazepine, were summarized in this report. ; U.S. Food and Drug Administration Clinical use of bulk drug substances nominated for inclusion on the 503B Bulks List Grant number: 5U01FD005946

In order to evaluate shared or phenotype-specific genetic predisposing factors for CBZ hypersensitivity reactions, we performed a meta-analysis of two genomewide association studies (GWAS) on a total of 43 well-phenotyped Northern and Southern European CBZ-SCAR cases and 10,701 population controls and a GWAS on 12 CBZ-DILI cases and 8,438 ethnically matched population controls. HLA-A*31:01 was identified as the strongest genetic predisposing factor for both CBZ-SCAR (odds ratio (OR) = 8.0; 95% CI 4.10-15.80; P = 1.2 × 10-9 ) and CBZ-DILI (OR = 7.3; 95% CI 2.47-23.67; P = 0.0004) in European populations. The association with HLA-A*31:01 in patients with SCAR was mainly driven by hypersensitivity syndrome (OR = 12.9; P = 2.1 × 10-9 ) rather than by Stevens-Johnson syndrome/toxic epidermal necrolysis cases, which showed an association with HLA-B*57:01. We also identified a novel risk locus mapping to ALK only for CBZ-SCAR cases, which needs replication in additional cohorts and functional evaluation. ; European Union (EU) European Union (EU) Instituto de Salud Carlos III Medical Research Council UK (MRC) United States Department of Health & Human Services National Institutes of Health (NIH) - USA NIH National Institute of Allergy & Infectious Diseases (NIAID) United States Department of Health & Human Services National Institutes of Health (NIH) - USA NIH National Institute of General Medical Sciences (NIGMS) Swedish Heart-Lung Foundation Swedish Research Council MRC Centre for Drug Safety Science International Serious Adverse Events Consortium (iSAEC) National Institute for Health Research (NIHR) Nottingham Digestive Diseases Biomedical Research ...
