In the pursuit of relief for the millions suffering from chronic cough, a condition that persists despite treatment, pharmaceutical giant Merck faced a significant setback. The company’s latest candidate, gefapixant, aimed at alleviating the distress of refractory chronic cough (RCC) and unexplained chronic cough (UCC) in adults, did not meet the substantial evidence of effectiveness as per the Food and Drug Administration (FDA).
On December 20, 2023, the FDA issued a complete response letter to Merck, which is based in Rahway, New Jersey. This letter indicates that the drug, which had reached the final stages of approval, failed to demonstrate the efficacy required for marketing authorization. While the details of the FDA’s feedback are confidential, Merck has publicly acknowledged that the concerns did not pertain to the safety of gefapixant, which may suggest that the treatment’s performance in clinical trials fell short in demonstrating a significant benefit for patients.
Chronic cough is a condition defined as a cough lasting more than eight weeks, which can lead to significant physical discomfort, social embarrassment, and reduced quality of life. RCC is particularly challenging as it persists despite interventions, while UCC lacks an identifiable cause. For patients, the impact is more than just physical—it’s a relentless disruption to their daily lives.
The quest for an effective treatment has been fraught with difficulty. A chronic cough can stem from multiple underlying conditions, such as asthma, gastroesophageal reflux disease (GERD), or postnasal drip. However, in cases of UCC, the lack of a clear cause leaves patients and doctors struggling for solutions. Merck’s gefapixant promised a new approach, one that targeted the nerves believed to be responsible for triggering the cough reflex.
Experts in the field of respiratory medicine have weighed in on the FDA’s decision, noting that while the outcome is disappointing, it underscores the rigorous standards required for new therapies. Clinical trials are the cornerstone of this process, designed to assess not just safety but also effectiveness before a drug can be deemed suitable for widespread use.
Statistics on chronic cough reveal the prevalence of the condition and the need for new treatments. Studies suggest that in the United States alone, approximately 10% of the population suffers from a chronic cough at any given time. Internationally, the numbers are thought to be similar.
Merck has stated that it will review the FDA’s feedback thoroughly to determine the necessary next steps. This could involve additional studies or modifications to the existing data to address the efficacy concerns raised. Patients and healthcare providers alike are keenly awaiting updates, hoping for a positive resolution that brings forward a new, effective treatment option.
The situation also highlights the complexities of drug development, especially for conditions with such variability as chronic cough. Success in the pharmaceutical industry is a delicate balance between innovation, regulation, and patient needs. Companies like Merck are constantly navigating these waters, aiming to bring forth solutions while adhering to the highest standards of safety and effectiveness.

FAQs
What is refractory chronic cough (RCC)? RCC is a persistent cough that continues despite attempts to treat any underlying conditions. It can significantly impact quality of life and is often difficult to manage due to its elusive nature.
What does a complete response letter from the FDA mean? A complete response letter from the FDA is an official notification that the agency has completed its review of a new drug application but has determined that the application is not ready for approval in its present form.
Are there any safety concerns associated with gefapixant? According to Merck, the complete response letter issued by the FDA regarding gefapixant was not related to safety issues. Instead, it pertained to the lack of substantial evidence of the drug’s effectiveness.
How prevalent is chronic cough in the general population? Research suggests that around 10% of the population in the United States experiences chronic cough at any given time. This condition is not only common but also significantly affects individuals’ well-being.
Will Merck continue to pursue approval for gefapixant? Merck is currently reviewing the FDA’s feedback and will determine the next steps. This may involve additional studies or revisions to address the efficacy concerns raised by the FDA.
