Stopping 5-ASA Therapy in Inactive Crohn's Disease

  • 5-ASA Withdrawal
  • Limited to 1580 patients
  • 1 Location

Crohn’s disease (CD) is a chronic inflammatory bowel disease characterized by diarrhea and
abdominal pain. Treatments include:

o 5-aminosalicylates, also known as 5-ASA (e.g. Asacol, Pentasa, Mezavant, Salofalk, and
o Steroids (e.g. Entocort, prednisone)
o Immunomodulators (e.g. Imuran, Purinethol, Rheumatrex)
o Biologics (e.g. Remicade, Humira, Entyvio)

5-ASAs are the most commonly prescribed drug class for CD however there is uncertainty regarding their effectiveness for treating CD. Despite this, doctors continue to prescribe a potentially ineffective treatment which, aside from costs ($23M in Canada/year), possibly delays the use of more effective treatments that could reduce the risk of preventable complications in patients, such as surgery.

The STATIC study is trying to determine if patients who stop taking their 5-ASA do no worse than those who continue taking their 5-ASA. Participants will be monitored for complications, surgeries or hospitalizations. The results of this study have potential to improve the lives of patients, change physician prescribing practice, and reduce health care costs.
