What Are the Current Market Dynamics for LIALDA?

Prevalence and Incidence of Ulcerative Colitis

• Global UC prevalence: Estimated to affect approximately 10-20 per 100,000 globally, with higher rates in North America and Europe.
• US epidemiology: Approximate prevalence of 238 per 100,000, with annual incidence rates of 8-15 per 100,000 (source: CDC, 2021).
• Implication: Rising UC cases drive demand for therapeutic agents such as LIALDA.

Therapeutic Market Segmentation

Segment	Description	Market Share (2022 Estimate)
Mesalamines (5-ASAs)	Oral and topical formulations for UC and Crohn’s disease	55%
Immunomodulators	Azathioprine, mercaptopurine	20%
Biologics	Infliximab, adalimumab, vedolizumab	20%
Corticosteroids	Prednisone, budesonide	5%

• LIALDA’s position: Represents the leading oral mesalamine formulation, with 30-40% of the mesalamine segment, positioned as an advanced-release option.

Competitive Landscape

Competitor	Product Name	Market Share (2022)	Key Differentiator
Pfizer	Asacol HD, Lialda	~40%	Once-daily dosing, improved tolerability
Gilead Sciences	Apriso	~25%	Extended-release, once daily
Salix Pharmaceuticals	Canasa, Rowasa	~15%	Rectal administration
