Gastroesophageal Reflux Disease Market in the US to Show Promising Growth at a CAGR of 6% During the Forecast Period (2025-2034) | DelveInsight

The gastroesophageal reflux disease market continues to be constrained by a limited number of approved treatment options and persistent unmet needs, particularly among patients who do not achieve adequate control with PPIs. Nevertheless, advancements in diagnostic approaches and the introduction of next-generation therapies, such as BLI5100 (Braintree Laboratories), linaprazan glurate (Cinclus Pharma), and others, are expected to sustain market growth from 2025 to 2034.

Gastroesophageal Reflux Disease Market Summary

• The market size for gastroesophageal reflux disease was found to be USD 3.3 billion in the United States in 2024.
• VOQUEZNA established its early presence as the first US P-CAB, and is projected to expand rapidly over the next decade as demand rises for faster and more durable acid suppression beyond conventional PPIs.
• The United States recorded approximately 33 million diagnosed prevalent GERD cases in 2024, highlighting the substantial and growing clinical burden of reflux disease across the population.
• Leading gastroesophageal reflux disease companies, such as Braintree Laboratories, Cinclus Pharma, and others, are developing new GERD treatment drugs that can be available in the GERD market in the coming years. 
• The promising gastroesophageal reflux disease therapies in clinical trials include BLI5100 (Tegoprazan), Linaprazan glurate, and others.

Key Factors Driving the Growth of the Gastroesophageal Reflux Disease Market 

• Rising GERD Prevalence: According to DelveInsight, the United States recorded approximately 33 million diagnosed prevalent GERD cases in 2024, highlighting the substantial and growing clinical burden of reflux disease across the population.
• Dominance of VOQUEZNA: VOQUEZNA (vonoprazan), developed by Phathom Pharmaceuticals, is the first approved PCAB for GERD in the US and delivers faster onset, more consistent acid suppression, and superior early healing versus lansoprazole, positioning it as a strong option for patients with high acid burden, nocturnal symptoms, or relapse during PPI tapering.
• Launch of Emerging Therapies: During the forecast period (2025–2034), pipeline candidates such as BLI5100 (tegoprazan) (Braintree Laboratories), Linaprazan glurate (Cinclus Pharma), and others are expected to drive growth in the 7MM GERD market.
• Emerging Role of Tegoprazan in Acid Suppression Therapy: The introduction of Tegoprazan, a potassium-competitive acid blocker, in Phase III trials presents an opportunity to address unmet needs and expand treatment options.

Gastroesophageal Reflux Disease Market Analysis

• GERD management is still dominated by generic PPIs and H2RAs, driven by long-standing physician familiarity and widespread OTC availability.
• Despite their use, PPIs show several drawbacks, including delayed onset of action, variable and incomplete acid suppression, reduced nocturnal control, and limited healing efficacy in moderate-to-severe erosive esophagitis (LA Grade C/D).
• Developed by Phathom Pharmaceuticals, VOQUEZNA is the first PCAB-approved for GERD in the U.S., offering faster onset, more consistent acid suppression, and superior early healing compared with lansoprazole.
• VOQUEZNA is well-suited for patients with high acid burden, persistent nocturnal symptoms, or relapse during PPI tapering.
• Two next-generation PCABs, BLI5100 (tegoprazan) from Braintree Laboratories (Sebela Pharmaceuticals) and linaprazan glurate from Cinclus Pharma, are in late-stage development and are expected to expand treatment options and compete with VOQUEZNA for patients inadequately controlled on standard PPI therapy.

Gastroesophageal Reflux Disease Competitive Landscape

BLI5100 (tegoprazan) from Braintree Laboratories (Sebela Pharmaceuticals) and linaprazan glurate from Cinclus Pharma are in late-stage development and are expected to compete with VOQUEZNA by providing additional options for patients who remain inadequately controlled on standard PPI therapy.

Braintree Laboratories' BLI5100 (tegoprazan) is a next-generation potassium-competitive acid blocker (P-CAB) to treat acid-related gastrointestinal disorders. Administered orally, it achieves rapid and durable suppression of gastric acid by directly blocking the proton pump within parietal cells, through a mechanism independent of H⁺/K⁺-ATPase activation that characterizes proton pump inhibitors (PPIs). Its molecular architecture allows interaction nearer the luminal surface of the pump, supporting a faster onset of action compared with conventional PPIs and potentially other P-CABs. BLI5100 is currently under evaluation in two Phase III clinical studies in the United States for erosive esophagitis and non-erosive reflux disease (NERD).

Cinclus Pharma's Linaprazan glurate is also a next-generation P-CAB and serves as the prodrug of linaprazan, originally discovered by AstraZeneca. It features a differentiated mechanism of action, enhanced pharmacokinetic properties, and the potential for improved therapeutic effectiveness. Clinical data indicate greater gastric acid suppression than that achieved with existing treatment options. The agent is being advanced for patients with moderate-to-severe erosive GERD and Helicobacter pylori infection who have an inadequate response to currently available therapies.

The anticipated launch of these emerging therapies are poised to transform the gastroesophageal reflux disease market landscape in the coming years. As these cutting-edge therapies continue to mature and gain regulatory approval, they are expected to reshape the gastroesophageal reflux disease market landscape, offering new standards of care and unlocking opportunities for medical innovation and economic growth.

Recent Developments in the Gastroesophageal Reflux Disease Market

• In October 2025, Cinclus Pharma Holding reported that it received favorable guidance from the US FDA following a recent Chemistry, Manufacturing, and Controls (CMC) meeting, endorsing the continued development of its lead candidate, linaprazan glurate.
• In October 2025, Phathom Pharmaceuticals announced that the results of additional analyses from its pivotal Phase III pHalcon-NERD-301 trial evaluating VOQUEZNA (vonoprazan) tablets in patients with NERD have been published in the American Journal of Gastroenterology.

What is Gastroesophageal Reflux Disease?

Gastroesophageal reflux disease (GERD) is a chronic digestive disorder in which stomach acid and, at times, bile flow back into the esophagus, the tube that connects the mouth to the stomach. This backflow, known as acid reflux, occurs when the lower esophageal sphincter (LES), a ring of muscle at the junction of the esophagus and stomach, becomes weak or relaxes inappropriately. Repeated exposure of the esophagus to stomach acid can irritate and damage its lining, leading to symptoms such as persistent heartburn, acid regurgitation, chest discomfort, difficulty swallowing, and chronic cough. If left untreated, GERD can result in complications including esophagitis, strictures, Barrett's esophagus, and an increased risk of esophageal cancer.
