Tailored Therapeutic Model According to the Expression of Genes in Inflammatory Bowel Disease Patients

Not Applicable
Completed
Conditions
Inflammatory Bowel Diseases
Interventions
Genetic: genotyping for three genes (TPMT, NUDT15 and FTO)
Other: non-genotyping
Registration Number
NCT03719118
Lead Sponsor
Yonsei University
Brief Summary

This study is a randomized controlled study conducted at five tertiary university hospitals. Patients who are 20-80 years old, diagnosed as having Inflammatory Bowel Disease(IBD) and who are planned to start thiopurines for the first time for the treatment of IBD are enrolled. Patients are assigned to the genotyping group or to the non-genotyping group. The patients who carry any heterozygotic variant among the three genes receive 50 mg azathioprine (AZA) or 25 mg of 6-mercaptopurine, while those who have any homozygotic variant are recommended to take other alternative drugs. The patients who do not carry any genetic variant or are assigned in non-genotyping group receive the standard dose of thiopurines based on the conventional approach.

Patients in the non-genotyping group receive the standard dose of thiopurines based on the conventional approach.
