New York, USA, Nov. 24, 2025 (GLOBE NEWSWIRE) -- Chronic Refractory Cough Market is Expected to Boom by 2034 Driven by Advancements in Treatment Options | DelveInsight

The chronic refractory cough market is expected to grow due to a rising diagnosed patient pool, greater awareness and recognition of chronic cough as a distinct condition, limitations of current off-label treatments, and the anticipated launch of emerging therapies with novel mechanisms of action including camlipixant (GSK), haduvio (nalbuphine ER) (Trevi Therapeutics), Taplucainium (Nocion Therapeutics) and others to address unmet needs in refractory patients.

DelveInsight’s Chronic Refractory Cough Market Insights report includes a comprehensive understanding of current treatment practices, emerging chronic refractory cough drugs, market share of individual therapies, and current and forecasted chronic refractory cough market size from 2020 to 2034, segmented into leading markets (the US, EU4, UK, and Japan).

Key Factors Driving the Growth of the Chronic Refractory Cough Market

Rising Chronic Refractory Cough Prevalence

The US accounted for approximately 13 million 12-month prevalent cases of chronic cough in 2024. These numbers are anticipated to rise by 2034, driven by the aging population that has an increased likelihood of developing chronic conditions such as asthma, COPD, and chronic cough.

Advancements in Diagnostics

New diagnostic techniques, such as cough reflex sensitivity testing, high‑resolution computed tomography (HRCT), and improved clinical protocols, improve the precision of diagnosis for refractory cough. Better diagnosis helps in tailored therapy, which in turn supports the adoption of specialized treatments.

Launch of Emerging Chronic Refractory Cough Drugs

The introduction of new therapies, including camlipixant (GSK), haduvio (nalbuphine ER) (Trevi Therapeutics), Taplucainium (Nocion Therapeutics), and others, is anticipated to further bolster the market throughout the forecast period (2025–2034).

Chronic Refractory Cough Market Analysis

Management of refractory chronic cough requires a multidisciplinary strategy combining pharmacological and non-pharmacological approaches. Pharmacologic treatments target neural sensitization and may include neuromodulators, proton pump inhibitors (PPIs) for gastroesophageal reflux, and inhaled corticosteroids (ICS) for airway inflammation. Non-pharmacological interventions focus on symptom control and quality of life, such as speech therapy for cough suppression, cognitive-behavioral therapy for psychological contributors, and airway clearance techniques to reduce mucus and triggers.

Currently, there is no FDA-approved therapy for RCC in the United States. Pharmacologic options mainly address heightened neural sensitivity and include neuromodulators such as opiates (morphine, codeine, tramadol), gabapentin, pregabalin, amitriptyline, and baclofen, along with PPIs, ICS, and antitussives.

LYFNUA (gefapixant) has been approved in Japan (2022) and the European Union (2023) for adults with refractory or unexplained chronic cough. While it is not yet FDA-approved in the U.S., its efficacy has been recognized internationally.

The RCC treatment landscape is advancing, with several promising candidates under development, including GSK’s camlipixant (GSK5464714), Trevi Therapeutics’ haduvio (nalbuphine ER), and Nocion Therapeutics’ taplucainium, among others.

Chronic Refractory Cough Competitive Landscape

The launch of emerging therapies, such as camlipixant (GSK), haduvio (nalbuphine ER) (Trevi Therapeutics), Taplucainium (Nocion Therapeutics), and others, is expected to further positively impact the market during the forecast period (2025–2034).

GSK’s Camlipixant is an orally administered, highly selective small-molecule P2X3 receptor antagonist that targets a validated pathway for refractory chronic cough. It is currently being evaluated in two pivotal Phase III trials, CALM-I and CALM-II, with the primary endpoint measuring changes in 24-hour cough frequency at Week 12 (CALM-I) and Week 24 (CALM-II). Topline results are anticipated in the second half of 2025, with GSK planning regulatory submissions and potential approvals in H2 2026.

Trevi Therapeutics’ Haduvio is under development for chronic cough in patients with idiopathic pulmonary fibrosis (IPF) and for renal cell carcinoma (RCC). It has a dual mechanism, acting as a kappa-opioid receptor agonist and a µ-opioid receptor antagonist, allowing it to suppress cough regardless of whether the trigger originates in the lungs or the central nervous system. This dual action blocks cough signals both centrally and peripherally, reducing cough independent of the initial stimulus.

Nocion Therapeutics’ Taplucainium (formerly NTX-1175) is a charged sodium channel blocker designed to silence activated pulmonary nociceptors while minimizing systemic exposure selectively. Unlike P2X3 antagonists, it accesses nociceptors via multiple large-pore channels, providing broad, rapid, and durable antitussive effects, supported by early safety and efficacy data. The Phase IIb ASPIRE trial is assessing once-daily inhaled Taplucainium powder (NOC-110) in adults with refractory or unexplained chronic cough.

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

What is Chronic Refractory Cough?

Chronic refractory cough is a persistent cough lasting more than 8 weeks that does not respond to standard treatments, despite thorough evaluation and management of common underlying causes such as asthma, gastroesophageal reflux disease (GERD), postnasal drip, or respiratory infections. Unlike ordinary chronic coughs, which often improve once the underlying condition is treated, chronic refractory cough continues to affect patients’ quality of life, leading to physical discomfort, sleep disturbances, social embarrassment, and, at times, psychological distress. Its persistence is often linked to heightened sensitivity of the cough reflex, a condition sometimes referred to as cough hypersensitivity syndrome, which can make even minor stimuli, like cold air or talking, trigger frequent coughing.

Chronic Refractory Cough Epidemiology Segmentation

The chronic refractory cough epidemiology section provides insights into the historical and current chronic refractory cough patient pool and forecasted trends for the leading markets. In the US, the gender-specific cases of chronic cough were nearly 5.1 million and 8 million cases for males and females, respectively, in 2024. Females are more susceptible to chronic cough due to various factors, including anatomical differences in the airways and heightened sensitivity to environmental triggers.
