Disease Overview:
Inflammatory bowel disease (IBD) is a chronic condition that affects the intestines. It develops when the body's immune system mistakenly targets healthy cells in the digestive tract, leading to persistent inflammation and tissue damage that does not resolve without treatment.
Ulcerative Colitis (UC)
- Ulcerative colitis (UC) is the most common type of inflammatory bowel disease (IBD).
- UC affects the inner lining of the colon and rectum, causing complete damage to the lining.
Crohn's Disease
- Crohn’s disease is a type of inflammatory bowel disease (IBD) that can affect any part of the digestive tract, from the mouth to the anus.
- It inflames areas of the intestine walls, causing patches of damage that can reach the outer lining
Epidemiology Analysis (Current & Forecast)
The prevalence of IBD is increasing due to the aging population worldwide. DataM estimates 359k incidence cases in 2023, with global prevalent cases of 4.84 million.

Approved Drugs (Current SoC) - Sales & Forecast
IBD treatment algorithm depends on the stage of the disease. Combination therapy provides good remission rates. Biologics are the most promising therapeutic option for IBD in the current scenario.
The current standard of care includes:
1. Aminosalicylates (5-ASA):
- Mesalamine: Available under brand names such as Lialda, Asacol, Pentasa, and Apriso, mesalamine is commonly used to treat mild to moderate ulcerative colitis by reducing inflammation in the lining of the colon.
- Sulfasalazine: Sold as Azulfidine, this medication combines sulfapyridine and 5-ASA, effective in treating mild to moderate ulcerative colitis and, in some cases, Crohn's disease.
2. Corticosteroids:
- Prednisone and Budesonide: These are utilized for the short-term management of moderate to severe IBD flare-ups due to their potent anti-inflammatory effects. Long-term use is generally avoided because of potential side effects.
3. Immunomodulators:
- Azathioprine and Mercaptopurine: These agents suppress the immune system to reduce inflammation and are often used when patients do not respond to standard therapies or to maintain remission.
4. Biologic Therapies:
- Anti-TNF Agents: Medications like infliximab (Remicade) and adalimumab target tumor necrosis factor-alpha (TNF-α), a pro-inflammatory cytokine, and are used in moderate to severe cases of IBD.
- Integrin Receptor Antagonists: Vedolizumab (Entyvio) is approved for adults with moderate to severe ulcerative colitis or Crohn's disease who have had an inadequate response to conventional therapy.
5. Janus Kinase (JAK) Inhibitors:
- Tofacitinib: An oral medication approved for moderate to severe ulcerative colitis, it works by inhibiting Janus kinase enzymes involved in the inflammatory process.
6. Recently Approved Treatments:
- Omvoh (mirikizumab): Approved by the U.S. FDA for the treatment of adults with moderate to severe Crohn's disease, expanding its previous indication for ulcerative colitis.
- Tremfya (guselkumab): Initially approved for psoriasis, its use has been expanded to include treatment for adults with ulcerative colitis.

Unmet Needs
Despite advancements in IBD therapies, several gaps remain in treatment options, patient outcomes, and disease management.
Below are some key unmet needs in IBD care:
Unmet Need | Challenges | Potential Solutions |
Disease Modification & Long-Term Remission | Current treatments manage symptoms but do not alter disease progression. | Develop therapies that prevent complications like fibrosis and strictures. |
More Effective & Safer Therapies | Only 30-40% of patients achieve remission, and many lose response over time. Some treatments have serious side effects. | Improve drug efficacy, reduce immunosuppressive risks, and develop new mechanisms of action. |
Faster-Acting Treatments | Many drugs take weeks to months to show effects, leaving patients with prolonged symptoms. | Develop rapid-onset therapies for acute disease flares. |
Personalized & Predictive Treatment | No reliable way to predict which drug will work best for each patient. | Use biomarkers and precision medicine approaches to tailor treatments. |
Treatment for Fibrosis & Strictures | No FDA-approved drugs specifically target fibrosis and strictures in Crohn’s disease. | Research antifibrotic drugs to prevent complications and reduce the need for surgery. |
Better Non-Invasive Monitoring | Colonoscopies are invasive, expensive, and inconvenient for regular monitoring. | Develop more reliable stool, blood, and imaging-based monitoring tools. |
Management of Extraintestinal Manifestations | Many IBD patients suffer from joint, skin, and eye inflammation, which current drugs do not effectively treat. | Develop therapies that address both intestinal and systemic symptoms. |
Mental Health & Quality of Life | High rates of anxiety and depression among IBD patients, but mental health care is often overlooked. | Integrate psychological support into IBD treatment plans. |
Cost & Access to Treatment | Biologic drugs are expensive, and insurance barriers delay treatment access. | Improve affordability, reduce insurance restrictions, and expand biosimilar availability. |
Pediatric & Elderly Treatment Gaps | Many clinical trials exclude children and older adults, leading to limited data on safe treatment. | Conduct more research to optimize therapies for these populations. |
Competitive Landscape and Market Positioning
The inflammatory bowel disease (IBD) market is highly competitive, with numerous pharmaceutical companies investing in innovative therapies to address unmet medical needs. The market includes biologics, small molecules, and emerging therapies, with companies competing based on efficacy, safety, cost, and patient convenience.
