BMS' Zeposia and AbbVie's Skyrizi Shake Up First-Line Prescribing Patterns in the US Ulcerative Colitis and Crohn's Disease Markets, Spherix Reports

US gastroenterologists estimate that just under 60% of their ulcerative colitis (UC) and 55% of their Crohn's disease (CD) patients treated with a biologic or small molecule are on their first-line advanced systemic therapy. Over the past eighteen months, the US inflammatory bowel disease (IBD) market has become increasingly competitive with the market entry of BMS' Zeposia and AbbVie's Rinvoq for the treatment of UC and AbbVie's Skyrizi in CD, which have had material changes to new start IBD treatment patterns.
