Effectiveness and Safety of Ustekinumab for Moderate to Severely Active Crohn's Disease: Results from an Early Access Program in Brazil.

ABSTRACT: This prospective, observational, open-label study aimed to provide access to ustekinumab prior to market authorization and assess its safety and effectiveness in patients with Crohn's disease (CD) refractory to anti-tumor necrosis factor-α and conventional drugs in Brazil. Patients with a diagnosis of moderate-to-severe active CD for ≥3 months before screening received ustekinumab in a single intravenous induction dose (~6 mg/kg) at week 0, and a 90 mg maintenance dose, subcutaneously, every 8 or 12 weeks, from week 8 through to 80. Serious adverse events (SAE), adverse drug reactions (ADR), clinical response (per CD Activity Index and Harvey Bradshaw Index (HBI) scores), remission (per HBI scores), biomarkers (C-reactive protein (CRP) and fecal calprotectin (FC)) and endoscopic improvemen
