A sample of the Gastroesophageal Reflux Disease Pipeline Review: the full chapter list, the tracker columns and two asset profiles from the report. The Research Desk reviews your request and emails it, usually within one business day.

Gastroesophageal Reflux Disease has 13 drug candidates in active clinical development, of which 6 are in Phase III, 0 in Phase II and 7 in Phase I, according to Douglas Insights' count of 142 interventional trials registered on ClinicalTrials.gov (data as of 4 Oct 2026).

The gastroesophageal reflux disease drug pipeline is the set of medicines that sponsors are still testing in people for this condition: each candidate is counted once, at the highest phase it has reached in a running or recently completed trial. Medicines already on the market and studied only in Phase IV trials are kept out of the count.

How many gastroesophageal reflux disease drugs are in each phase of development?

Douglas Insights counts 6 gastroesophageal reflux disease candidates in Phase III, 46% of the 13 assets in development; Phase II holds 0 and Phase I holds 7.

Phase III646%
Phase II00.0%
Phase I754%
Total13100%

Phase I/II candidates sit in the Phase I row and Phase II/III candidates in the Phase II row, so each gastroesophageal reflux disease asset appears in exactly one row. The 45 trials still recruiting or running carry 32% of the 142 registered trials in scope.

Which approved gastroesophageal reflux disease medicines are still in trials?

7 medicines already on the market are still being tested in gastroesophageal reflux disease Phase IV trials; Esomeprazole has the most, with 17 registered trials.

EsomeprazoleSeveral sponsors17

Post-approval gastroesophageal reflux disease trials test new doses, new patient groups and head-to-head comparisons. They set the standard of care that every candidate in development will be measured against, so the paid review profiles each one.

How many gastroesophageal reflux disease trials are recruiting patients now?

24 gastroesophageal reflux disease trials are recruiting patients and 15 more have not started recruiting yet, out of 142 interventional trials in scope; together they make up 27% of the trial base.

Registry statusTrialsShare

Status not verified2014%
Not yet recruiting1511%
Withdrawn64.2%
Terminated64.2%
Active, not recruiting42.8%
Enrolling by invitation21.4%

Terminated, suspended and withdrawn gastroesophageal reflux disease trials stay in the trial base so that a stalled programme is visible, but a candidate whose only trials stopped is no longer counted as in development.

Which companies lead the gastroesophageal reflux disease pipeline?

Addpharma Inc. leads the gastroesophageal reflux disease pipeline with 2 candidates; the top 5 sponsors hold 54% of the 13 assets, and 11 sponsors run at least one.

SponsorAssets in developmentShare
Addpharma Inc.215%
Korea United Pharm. Inc.215%
Xuanzhu Biopharmaceutical Co., Ltd.17.7%
Braintree Laboratories17.7%
Daewon Pharmaceutical Co., Ltd.17.7%

Industry sponsors lead 66 of the 142 gastroesophageal reflux disease trials (46%); universities, hospitals and public funders lead the rest. A sponsor is credited with an asset when it is the lead sponsor on most of that asset's industry trials.

Which drug types and mechanisms dominate the gastroesophageal reflux disease pipeline?

Mechanism and drug-type classification for the 13 gastroesophageal reflux disease candidates is done by the research desk asset by asset, each with a cited source, and is published in the paid review together with the white-space map.

What gastroesophageal reflux disease trial readouts are coming next?

0 gastroesophageal reflux disease candidates in Phase II or later have a registered primary completion date in the next 12 months; the next three are below, each linked to its registry record.

CandidateSponsorPhasePrimary completionRegistry
JP-1366Onconic Therapeutics Inc.Phase IIIOct 2028 (estimated)NCT07732075

Primary completion is the date a sponsor expects the last patient to finish the main measurement, so data usually follow within months. Dates marked estimated are the sponsor's own forecast on the registry and often move.

How many gastroesophageal reflux disease readouts fall in each quarter?

0 gastroesophageal reflux disease candidates in Phase II or later reach registered primary completion over the next eight quarters, with the most, 0, due in Q4 2026.

Each candidate is counted once, at its next readout. The paid catalyst calendar names every readout with its trial, sponsor and design, adds filings and regulatory decisions, and runs 24 months ahead.

Which countries host the most gastroesophageal reflux disease trials?

United States hosts the most gastroesophageal reflux disease trials, with sites in 42 of the 142 studies (30%); trials in scope run in 43 countries in all.

South Korea2115%
China1611%
Italy85.6%
Sweden53.5%
France42.8%
Egypt42.8%
Taiwan32.1%

A multinational gastroesophageal reflux disease trial is counted once in every country where it has a site, so the shares add up to more than 100%. Country spread shows where sponsors are building the evidence that regulators in each market will ask for.

Where are gastroesophageal reflux disease drugs being tested?

42 of the 142 gastroesophageal reflux disease trials (30%) have a site in the United States, 29 (20%) in Europe and 16 (11%) in China; 3 of the 13 candidates in development are tested in the US.

Rest of world5035%10national regulators

Each region's trials are the evidence its regulator will review: the FDA in the United States, the EMA (with the MHRA and Swissmedic) in Europe, the NMPA in China and the PMDA in Japan. A multinational gastroesophageal reflux disease trial counts once in every region where it has a site, so the shares add up to more than 100%. A candidate tested only outside the US and Europe is often a licensing opportunity for sponsors in those markets.

What has changed in the gastroesophageal reflux disease pipeline since the last update?

This is the first edition of the gastroesophageal reflux disease pipeline count, dated 4 Oct 2026. The next refresh is due by 2 Jan 2027, and each refresh lists the assets that entered, advanced or dropped out.

How does Douglas Insights count the gastroesophageal reflux disease pipeline?

Douglas Insights read 142 interventional trials registered on ClinicalTrials.gov for the conditions "Gastroesophageal Reflux", "GERD" and updated since 4 Oct 2021, then grouped every drug or biologic named in them into 13 unique candidates.

  1. Code names, generic names and brand names of the same molecule are merged into one candidate, and every merge is reviewed by the research desk.
  2. A candidate counts when it has a trial that is recruiting, running, or completed in the last 24 months, and at least one industry-sponsored trial.
  3. Its phase is the highest phase among those trials; placebo, standard-of-care and comparator arms are not candidates.
  4. Each figure on this page is drawn from one frozen dataset that passes ten checks before release, and the owner approves every edition.
