Effectiveness and Safety in Administrating CNU® Capsule to Refractory Functional Dyspepsia Patients

• Status: Recruiting
• Trial end date: 2021-12-30
• Target enrollment: 0
• Participant gender: All

Summary

Refractory Functional Dyspepsia (FD) means a state that no symptom was improved in spite of appropriate treatment for the FD.

It may be challenging to discriminate the symptoms of FD from the symptoms of bile dyspepsia resulting from the biliary system. As the bile dyspepsia may induce epigastralgia as with functional dyspepsia and both imaging medical tests and blood tests show normal findings, it is difficult to discriminate it from the FD with only these tests.

Thus this study intends to perform a therapeutic use clinical study for efficacy and safety on symptom improvement by administrating CNU capsule to the patients with RFD.
