Effectiveness and Safety in Administrating CNU® Capsule to Refractory Functional Dyspepsia Patients
Study Details
Study Description
Brief 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.

Detailed Description
Functional Dyspepsia means a pain or discomfort of epigastrium originated from the stomach or duodenum without any causative organic or metabolic disease. For its standard criteria, "Rome IV diagnosis criteria" was used, where more than on symptoms including bothersome postprandial fullness, early satiation, epigastric pain, and epigastric soreness should have been elicited at least 6 months before and continued for at least 3 months in total.
Refractory Functional Dyspepsia means a state that no symptom was improved in spite of appropriate treatment for the functional dyspepsia.
The pathogenesis of Functional Dyspepsia has not been fully identified yet. Its standard therapies include prokinetics, analgesics, H2-receptor antagonists, proton pump inhibitors, antacids, serotonin receptor antagonists, proton pump inhibitors, antacids, serotonin receptor antagonists, and antidepressants. As these therapies has lower efficacy and drug related adverse reactions, the RFD patients who do not respond to medication need another therapeutic option.
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.
Therefore even though the epigastralgia or upper abdominal discomfort met the Rome IV criteria for the FD, the possibility that it, in part was actually resulted from the bile dyspepsia cannot be eliminated.
The CNU capsule is a choleretic used for bile dyspepsia as a complex agent of trihydrated magnesium salt of kenodeoxycholic acid and ursodeoxycholic acid, which are being marketed.
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.

Outcome Measures
Primary Outcome Measures
- Improvement of symptoms [12weeks after CNU capsules]
The primary outcome variable will be the percentage of subjects to report that they are improved or unchanged or deteriorated or No assessable in overall symptoms compared to baseline on a 7-point Global Overall Symptom Scale (GOS). The GOS is assessed on a 7-point scale, with the severity scale from 1 (Normal, not at all ill) through to 7 (Among the most severely ill patients).
Secondary Outcome Measures
- The Total Number of subjects Experiencing at Least one Adverse Event During the study [for 12 weeks]
An Adverse Event (AE) is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.
