Helicobacter pylori (H. pylori) Infection - Market Insights, Epidemiology, and Market Forecast - 2036

Helicobacter pylori (H. pylori) Insights and Trends

• According to DelveInsight's analysis, H. pylori infection market size was found to be ~USD 270 million in the leading markets (the United States, the EU4 (Germany, France, Italy, and Spain), the United Kingdom) in 2025.
• H. pylori infection burden is decreasing overall due to improved hygiene, sanitation, living conditions, and widespread antibiotic use, which have reduced transmission, especially in younger generations. However, prevalence remains high in Spain in both children and adults because of persistent intrafamilial transmission, historical high infection rates in older cohorts, and regional socioeconomic and household crowding factors that continue to support early-life exposure and ongoing spread.
• There is a growing emphasis on "precision medicine" for H. pylori infection, utilizing molecular testing (e.g., PCR) to detect resistance mutations (such as 23S rRNA for clarithromycin) prior to treatment, allowing for tailored therapy rather than empirical guessing.
• The persistence of high eradication failure rates has significant clinical and public health implications, prolonging exposure to H. pylori-associated disease and exacerbating downstream effects of repeated treatment, particularly the emergence of antibiotic resistance.
• The current H. pylori treatment landscape includes key combination therapies such as omeprazole magnesium, amoxicillin, and rifabutin (TALICIA), vonoprazan-based dual and triple regimens (VOQUEZNA DUAL/VOQUEZNA TRIPLE PAK), and bismuth, metronidazole, and tetracycline (PYLERA), reflecting ongoing optimization of eradication strategies and adaptation to resistance patterns.
• While the emerging H. pylori infection pipeline remains limited, with only a few therapies currently in development, including ifasutenizol (TNP-2198; TenNor Therapeutics), Linaprazan glurate (Cinclus Pharma), and Tegoprazan/RQ-00000004 (RaQualia Pharma/HK-inno.N/Braintree).
• A major unmet need in H. pylori infection is the lack of updated epidemiological and antibiotic resistance data, particularly in developed countries, limiting accurate disease burden assessment and hindering optimized prevention and treatment strategies.

Helicobacter pylori (H. pylori) Infection Understanding and Treatment Algorithm

Helicobacter pylori (H. pylori) Infection Overview and Diagnosis

Helicobacter pylori (H. pylori) is a spiral-shaped, flagellated, gram-negative, microaerophilic bacterium that infects the stomach lining. The infection is usually acquired in childhood and can persist for years if untreated, often leading to chronic gastritis and peptic ulcer disease, and increasing the risk of gastric cancer and MALT lymphoma.

The diagnosis of active H. pylori infection requires detection of the bacterium and its activity, using noninvasive or invasive methods. Non-invasive tests, primarily the UBT and SAT, are highly sensitive and specific, whereas serologic IgG testing cannot reliably distinguish active from past infection. Invasive approaches, including upper endoscopy with biopsy, provide confirmatory evidence through histology, RUT, culture, or PCR; culture offers definitive specificity and enables antibiotic susceptibility testing, but is technically demanding and less sensitive. Standard clinical practice confirms infection using either two positive noninvasive tests or at least two positive invasive tests (e.g., histology plus urease).

Current Helicobacter pylori (H. pylori) Infection Treatment

Treatment of H. pylori infection in children and adolescents aims for high eradication rates and is guided by bacterial susceptibility to clarithromycin (CLA) and metronidazole (MET), as well as the child's age and weight. For CLA- and MET-susceptible strains, standard first-line triple therapy with a PPI, amoxicillin, and clarithromycin for 14 days is preferred, with clarithromycin replaceable by metronidazole after treatment failure. In areas with high or unknown clarithromycin resistance, optimized bismuth quadruple therapy (PPI, bismuth, tetracycline or amoxicillin in younger children, and metronidazole) is recommended, while alternative regimens include rifabutin-based triple therapy (TALICIA) or vonoprazan-amoxicillin dual therapy (VOQUEZNA). Sequential therapy may be considered for fully susceptible strains but should be avoided in resistant infections. For strains resistant to both CLA and MET, or when susceptibility is unknown, bismuth quadruple therapy is preferred, with rescue therapy guided by susceptibility testing to maximize eradication.

Helicobacter pylori (H. pylori) Infection Epidemiology

Key Findings from H. pylori Infection Epidemiological Analysis and Forecast

• According to DelveInsight's estimates, the total diagnosed prevalent cases of H. pylori infection in the 6MM were approximately ~148 million in 2025.
• In 2025, Spain accounted the highest number of diagnosed prevalent cases of H. pylori infection while the UK accounted for the least number of cases of the total diagnosed prevalent population in EU4 and the UK.
• In the US, age-specific trends in H. pylori infection show a clear correlation with increasing age, with prevalence generally rising among older adults. The infection is often acquired in childhood, and prevalence increases across adult age groups, reflects historical exposure and slower decline in older cohorts.

Helicobacter pylori (H. pylori) Infection Market Outlook

The H. pylori infection treatment landscape is undergoing a gradual shift as rising antibiotic resistance challenges traditional eradication regimens based on proton pump inhibitors and standard antibiotics. Recently approved therapies such as TALICIA (rifabutin-based triple therapy) and VOQUEZNA (vonoprazan-based dual and triple regimens) represent key advancements in eradication strategies. TALICIA targets resistant strains through rifabutin's bactericidal activity by inhibiting bacterial RNA polymerase, while VOQUEZNA introduces a PCAB mechanism that provides stronger and more sustained acid suppression compared to conventional PPIs, thereby improving eradication outcomes and expanding treatment options.

With advancing candidates such as rifasutenizol (TenNor Therapeutics), the field is evolving toward targeted antibacterial therapies designed to overcome resistant H. pylori strains and address unmet eradication needs.

Overall, launch of novel eradication therapies, increasing awareness of antibiotic resistance, and improved diagnostic practices are expected to drive steady growth in the 6MM H. pylori infection market from 2022-2036, with strong commercial implications for both marketed products and the emerging pipeline.

• Among the 6MM, the United States accounted for the largest market size of H. pylori infection. i.e., ~USD 230 million in 2025.
• In 2036, among all the therapies for H. pylori Infection, the highest revenue is estimated to be generated by Vonoprazan (VOQUEZNA Dual & Triple Pak), in the United States.
• Regional dynamics show the US leading in market revenue, while European markets exhibit steady growth, reflecting increasing antibiotic resistance awareness and greater adoption of novel regimens such as vonoprazan- and rifabutin-based therapies.
