Key Factors Driving the Growth of the Ulcerative Colitis Market 

Rising ulcerative colitis prevalence

As per DelveInsight's analysis, in 2024, the US accounted for approximately  1.5 million diagnosed prevalent cases of ulcerative colitis. These are expected to increase during the forecast period (2025−2034) due to advancements in medical technology, allowing for better diagnosis and treatment.

Advancements in biologics and targeted therapies

Biologic drugs such as anti‑TNF agents, integrin antagonists, and IL‑23 inhibitors have become the backbone of treatment for moderate‑to‑severe UC, supporting strong revenue growth as adoption widens. Next‑generation targeted therapies, including oral JAK inhibitors and S1P receptor modulators, are reshaping treatment algorithms by offering high efficacy and improved convenience, thereby accelerating market expansion.

Launch of ulcerative colitis drugs 

The anticipated launch of ulcerative colitis drugs such as obefazimod (Abivax), tulisokibart (Merck), Afimkibart (RVT 3101) (Roche), MORF-057 (Eli Lilly), and others will drive the market forward in the coming years.

Ulcerative Colitis Market Analysis

For patients with mild-to-moderate ulcerative colitis, current U.S. treatment guidelines recommend beginning therapy with aminosalicylates or using corticosteroids for induction followed by aminosalicylate-based maintenance. In cases of moderate-to-severe disease, maintenance therapy after corticosteroid induction may involve immunosuppressants such as azathioprine or 6-mercaptopurine. Another option is the use of biologics, most commonly anti-TNF agents like infliximab or adalimumab, with or without immunosuppressants, to achieve and sustain mucosal healing and clinical remission. Despite these recommendations, real-world patterns of care for moderate-to-severe ulcerative colitis remain insufficiently understood.

The therapeutic landscape has broadened considerably with the approval of newer agents, including TREMFYA (guselkumab, J&J), SKYRIZI (risankizumab, AbbVie), VELSIPITY (etrasimod, Pfizer), and OMVOH (mirikizumab, Eli Lilly), demonstrating a shift toward more targeted biologics and innovative oral therapies that provide alternatives to traditional treatment approaches.

Although significant progress has been made, safety remains a major limitation in the management of ulcerative colitis. A truly safe and curative option is still lacking, and many patients experience a marked decline in quality of life. While available therapies are effective for some individuals with ulcerative colitis and Crohn's disease, many others require multiple lines of treatment, indicating a persistent unmet need for new therapeutic strategies. To address these challenges, leading pharmaceutical companies are collaborating to develop next-generation solutions.

Ulcerative Colitis Competitive Landscape

The ulcerative colitis clinical trial landscape includes some drugs in mid- and late-stage development that are expected to be approved in the near future. The emerging landscape offers a diverse range of therapeutic alternatives, including obefazimod (Abivax), tulisokibart (Merck), Afimkibart (RVT 3101) (Roche), MORF-057 (Eli Lilly), and others across different lines of treatment. 

Abivax's ABX464 is an oral, first-in-class small molecule that selectively enhances miR-124 expression in immune cells. It has shown a favorable safety profile and potent anti-inflammatory effects across preclinical studies and Phase IIa and Phase IIb induction trials for ulcerative colitis. Its mechanism of action is distinct because it markedly increases miR-124 production, a unique RNA-splicing product with anti-inflammatory properties. Clinical evidence indicates that ABX464 may help patients achieve remission and promote healing of inflammatory lesions associated with ulcerative colitis.

Merck's Tulisokibart is an investigational humanized monoclonal antibody that targets tumor necrosis factor (TNF)-like ligand 1A (TL1A). It became part of the pipeline following the acquisition of Prometheus Biosciences. The therapy is currently in Phase III clinical development for ulcerative colitis. In a Phase II study (NCT04996797), tulisokibart demonstrated superior efficacy to placebo in achieving clinical remission in patients with moderately to severely active ulcerative colitis.

The anticipated launch of these emerging therapies are poised to transform the ulcerative colitis market landscape in the coming years. As these cutting-edge therapies continue to mature and gain regulatory approval, they are expected to reshape the ulcerative colitis market landscape, offering new standards of care and unlocking opportunities for medical innovation and economic growth.

Recent Developments in the Ulcerative Colitis Market

• In November 2025, Abivax announced results from the Phase III ABTECT induction trials of obefazimod, which showed significant improvements in quality of life for patients with moderate to severe ulcerative colitis.
• In July 2025, Abivax announced positive Phase III results from both ABTECT 8-week induction trials investigating Obefazimod, its first-in-class oral miR-124 enhancer, in moderate to severely active ulcerative colitis
• In April 2025, Johnson & Johnson announced that the European Commission had approved a Marketing Authorisation for TREMFYA (guselkumab) for the treatment of adult patients with moderately to severely active ulcerative colitis.

What is Ulcerative Colitis?

Ulcerative colitis is a chronic inflammatory bowel disease that causes long-lasting inflammation and ulcers in the lining of the large intestine, primarily affecting the colon and rectum. It occurs when the body's immune system mistakenly attacks the cells of the intestinal lining, leading to symptoms such as abdominal pain, persistent diarrhea, blood or mucus in stool, fatigue, and unintended weight loss. UC typically progresses in cycles of flare-ups and remission, with symptoms intensifying and then subsiding. Although the exact cause is unknown, a combination of genetic, environmental, and immune-related factors is believed to contribute to its onset. While there is currently no cure, proper medical management, diet adjustments, and lifestyle modifications can help reduce inflammation, control symptoms, and improve quality of life for individuals living with the condition.
