DLBS2411 Treatment For Functional Dyspepsia

Randomized Controlled Trial of DLBS2411 Treatment For Functional Dyspepsia

This is a 2-arm, prospective, double-blind, randomized and placebo-controlled study using DLBS2411 at a dose of 250 mg twice daily (before morning and evening meals), for a 4-week course of therapy, for the treatment of patients with functional dyspepsia (FD), and an additional 8 weeks after end of therapy (Week 12) for follow-up visit.

The bioactive fraction of DLBS2411 has been proved at cellular and genetic levels to have an antiulcer effect through both suppressing the gastric acidity and enhancing gastric mucosal protection. The anti-secretory effect of DLBS2411 is exerted through the inhibition of H+/K+ ATPase 'pump' as well as down-regulation of the H+/K+ ATPase gene expression, thus suppressing gastric acid secretion; while its cytoprotective defense mechanism works through the promotion of cyclooxygenase-2 (COX-2) derived prostaglandin (PgE2) synthesis, thus promoting gastrointestinal submucosal blood-flow, stimulating secretion of gastric-epithelial mucous and bicarbonate; anti-oxidative activity; and endothelial-nitric oxide (NO) formation. The mechanism altogether demonstrated DLBS2411's protective capacity to the gastric and colon mucosa by promoting mucous synthesis and stimulating mucosal blood flow.

Having such mechanisms of action, DLBS2411 is hypothesized to benefit subjects with gastric acid disorders such as in functional dyspepsia, gastro-intestinal reflux disease (GERD), peptic-ulcer, and irritable bowel syndrome (IBS).

Study Overview

• Status: Recruiting
• Conditions: Functional Dyspepsia
• Intervention / Treatment: Drug: Placebo caplet of DLBS2411; Drug: DLBS2411

Detailed Description

Study population will be patients with functional dyspepsia (FD) who come to the study site. There will be 100 subjects (50 subjects in each group) planned to be enrolled in the study.

There will be 2 groups of treatment; Treatment 1: placebo DLBS2411 caplet Treatment 2: DLBS2411 250 mg caplet Each study medication will be administered 1 caplet twice daily, 30 minutes before meal, in the morning and evening.

Eligible subjects will be randomly allocated to receive either Treatment 1 or Treatment 2 for 4 weeks, in a double blind fashion. Subjects will be instructed to come to the clinic every 2-week interval throughout the 4-week study period (at Week 2, and 4, respectively) and 8 weeks after the end of therapy (Week 12), for efficacy evaluation. The safety evaluation will be performed at Baseline and End of therapy (Week 4). Adverse events will be monitored at baseline and every follow-up visit including End of study (Week 12).

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Short-Form Nepean Dyspepsia Index (SF-NDI)	Change of disease specific quality of life as measured by short-form NDI (SF-NDI) after 4 weeks of therapy (Week 4). The SF-NDI consists of 10 quality-of-life (QoL)-items, each of which is measured by 5-point Likert scales from 0 (not at all or not applicable), 1 (a little), 2 (moderately), 3 (quite a lot) to 4 (extremely). The lower score indicates an improved outcome.	Week 4

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Short-Form Nepean Dyspepsia Index (SF-NDI)	Change of disease specific quality of life as measured by short-form NDI (SF-NDI) after 2 weeks of therapy (Week 2) and additional 8 weeks after end of therapy (Week 12). The SF-NDI consists of 10 quality-of-life (QoL)-items, each of which is measured by 5-point Likert scales from 0 (not at all or not applicable), 1 (a little), 2 (moderately), 3 (quite a lot) to 4 (extremely). The lower score indicates an improved outcome.	Week 2 and 12
Visual Analogue Scale (VAS)	Change of the individual symptom intensity as indicated by Visual Analogue Scale (VAS) reduction after 2 and 4 weeks of therapy and 8 weeks after the end of therapy (Week 2, 4 and 12, respectively). The VAS of pain intensity is rated from 0 to 100 on a 100-mm line, with the end points indicating: no pain (0) and the worst pain it could possible be (100).	Week 2, 4, and 12
The proportion of subjects reaching adequate / satisfactory relief from FD symptoms	The proportion of subjects reaching adequate / satisfactory relief from FD symptoms based on subjects" subjective evaluation on overall symptom relief at Week 2, Week 4 and additional 8 weeks after end of therapy (Week 12)	Week 2, 4, and 12
