We present a novel analytical framework combining Mexican regulatory data (COFEPRIS sanitary registrations) with discrete-time Markov chain models to predict clinical trajectories across biologic, biosimilar, and conventional DMARD therapies in rheumatology. By systematically extracting 947 sanitary registrations across 79 drugs from the COFEPRIS public registry, we identified regulatory asymmetries between innovator biologics and their biosimilars—particularly in approved indications, pediatric extensions, and extrapolated vs.

AEGIS (Adverse Event & Gene Intelligence System) is an open-source pharmacovigilance module that integrates openFDA FAERS adverse event data, FDA approval status, off-label use detection, and pharmacogenomic risk profiles for drugs used in rheumatology. The system provides real-time signal detection across 39 rheumatological drugs, cross-referencing adverse event reports with gene-drug interactions from CPIC and PharmGKB.
