About this study

Official title: Efficacy and Safety of DLBS2411 Compared to Omeprazole in the Management of Gastroesophageal Reflux Disease (GERD)

This is a 2-arm, prospective, double-blind double-dummy, randomized-controlled study comparing DLBS2411 at a dose of 250 mg twice daily with omeprazole at a dose of 20 mg twice daily, given before morning and evening meals, for an 8-week course of therapy. Subjects should avoid taking meals 2-3 hours before bedtime.

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.

Recent study of DLBS2411 which was conducted in healthy volunteers, demonstrated the effective role and safety of DLBS2411 in suppressing intragastric acidity. Having such mechanisms of action, DLBS2411 is hypothesized to benefit patients with gastric acid disorders such as in gastroesophageal reflux disease (GERD).

Read the detailed description

There will be 2 groups of treatment; each group will consist of 129 subjects with the treatment regimens for 8 weeks:

Treatment I : 1 capsule of Omeprazole 20 mg and 1 placebo caplet of DLBS2411, twice daily Treatment II : 1 caplet of DLBS2411 250 mg and 1 placebo capsule of omeprazole, twice daily

Each study medication will be administered twice daily, 30 minutes before morning (the first) and evening (the last) meals.

The eligible subjects will be randomly allocated to receive study medication (Treatment 1 or Treatment 2) for 8 weeks of treatment, in a double blind fashion. They will be asked to come to the clinic every 4-week interval throughout the study period. Treatment Group 1 will receive Omeprazole twice daily and Placebo DLBS2411 twice daily. While Treatment Group 2 will receive DLBS2411 twice daily and Placebo Omeprazole twice daily.

Subjects will be evaluated for treatment efficacy at baseline and at interval of 4 weeks over the 8-week course of therapy. Throughout the 8-week therapy, subjects should record the frequency (presence and absence) of each of GERD symptoms (heartburn, regurgitation, epigastric pain, nausea) daily in the provided Patient's Diary. The severity of each symptom experienced should also be self-evaluated and recorded.

The safety profile of study medication other than vital signs and adverse event will be measured at baseline and end of study.

Along the study, subjects should avoid taking meals 2-3 hours before bedtime. All subjects will be under direct supervision of a medical doctor during the study period.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Healing rate by endoscopy

    Healing rate is defined as proportion of subjects with either complete or achieving lower endoscopic grade of esophagitis (according to the Los Angeles (LA) classification) at Week 8 (end of study).

    Measured: 8 weeks

Secondary outcomes (10)
  1. Changes in GERD Questionnaire (GERDQ) sum scores

    Changes in GERDQ sum scores from baseline to Week 4 and Week 8 of treatment.

    Measured: 4 and 8 weeks

  2. Composite heartburn and regurgitation response rate

    Composite heartburn and regurgitation response rate: defined as proportion of subjects with neither heartburn nor acid regurgitation during the last 7 days (complete resolution of heartburn and acid regurgitation) by Week 4 and Week 8.

    Measured: 4 and 8 weeks

    Regurgitation response rate: defined as proportion of subjects with no regurgitation during the last 7 days (complete resolution of regurgitation) by Week 4 and Week 8 (end of study).

    Measured: 4 and 8 weeks

  5. Overall response rate

    Overall response rate: defined as proportion of subjects with controlled GERD symptoms by Week 4 and 8 of treatment, defined as proportion categorized as:

    • complete relief (no GERD symptoms during the last 7-day);
    • partial relief (a decrease in frequency but not complete relief of GERD symptoms during the last 7-day); and
    • no response (increase or no change in frequency of GERD symptoms).

    Measured: 4 and 8 weeks

  6. Vital sign

    Vital sign (blood pressure) from baseline to every follow-up visit including end of study

    Measured: 4 and 8 weeks

  7. Electrocardiography (ECG)

    Electrocardiography (ECG) at baseline and at the end of study

    Measured: 8 weeks

  8. Liver function

    Liver function (serum alanine aminotransferase (ALT), serum aspartate aminotransferase (AST), alkaline phosphatase, total bilirubin)from baseline to every follow-up visit including end of study

    Measured: 4 and 8 weeks

  9. Renal function

    Renal function (serum creatinine and blood urea nitrogen (BUN) level) from baseline to every follow-up visit including end of study

    Measured: 4 and 8 weeks

  10. Adverse event

    Adverse event, will be observed throughout the study conduct

    Measured: 4 and 8 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Omeprazole and DLBS2411 in people with Gastroesophageal Reflux Disease (GERD), run by Dexa Medica Group at 5 sites in Indonesia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 7 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in Indonesia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Very low recruitment rate. The Study Site classifies as tertiary referral hospital. Therefore, GERD Patients being referred to the site are mostly those with comorbidities included in the exclusion criteria.). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Healing rate by endoscopy (time frame: 8 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Jan 2021.
