Research in Crohn’s Disease poised to change the Treatment Landscape

04 May Research in Crohn’s Disease poised to change the Treatment Landscape

Crohn’s is an inflammatory bowel disease characterized by chronic inflammation of the gastrointestinal tract, chronic diarrhea, abdominal cramps, rectal bleeding and constipation to name a few. It is estimated that Crohn’s disease affects 780,000 Americans, with the highest prevalence being between the ages of 15 and 35.

Research in recent years points to genetics, hereditary factors and environmental factors as the most likely cause for the disease while improper diet and stress are known to aggravate the condition. According to a report by the Centers for Disease Control and Prevention (CDC) there are 3.1–14.6 new diagnosis of Crohn’s per 100,000 people each year. The economic burden of this disease is an estimated $25,282–$26,192 per annum according to a study.

The current treatment options include therapeutics such as immunomdulators, aminosalicylates, antibiotics antidiarrheals and steroids. There is no cure available and the medication is essentially to provide symptomatic relief. Surgery is an option and according to an estimate by the NIDDK nearly 60 percent of people will need surgery within 20 years of a Crohn’s disease diagnosis.

A report by Grand View Research predicts that the market for Crohn’s Therapeutics will reach USD 4.7 billion by 2025, growing at a CAGR of 2.4%. Increasing awareness, government and regulatory support to innovative treatment solutions along with improved diagnostic services will aid the growth of the market.

We take a look at some companies that are engaged in addressing the unmet needs in this field.
