  • A study was conducted in Brazil to evaluate the effectiveness and safety of ustekinumab (UST) in treating ulcerative colitis (UC), a condition with limited real-world data in Latin America.
  • The research included 50 patients with moderate-to-severe UC, focusing on their clinical and endoscopic remission after one year of UST treatment; 50% achieved clinical remission, while 36% achieved endoscopic remission.
  • The safety profile revealed that 20% of patients were hospitalized and 18% discontinued the drug mainly due to lack of effectiveness, but the treatment persistence rate at 24 months was 73.7%.
