Merck & Co.’s recent acquisition of Verona Pharma for $10 billion marks a significant milestone for the company, as it has spent the last two decades developing a respiratory drug known as Ohtuvayre. Despite the fact that the drug’s principal patent expired before former President Joe Biden took office, Merck and Wall Street analysts are optimistic about its potential for blockbuster sales.
Ohtuvayre received U.S. approval in 2024, making it the first new type of inhaled treatment for chronic obstructive pulmonary disorder (COPD) in many years. The drug works by relaxing airway muscles and reducing inflammation, providing relief to patients with the lung disorder. Sales of Ohtuvayre have been strong, reaching $71 million in the first quarter alone, with projections suggesting it could generate up to $4 billion in annual revenue.
In order to achieve and maintain such high sales figures, Merck will need to protect and expand the intellectual property surrounding Ohtuvayre. CEO Robert Davis expressed confidence in the company’s ability to safeguard the drug’s patent rights through the mid-2030s. This means that Ohtuvarye may not face competition for nearly three decades after its main compound was initially patented in 2003.
Verona Pharma, the original developer of Ohtuvayre, faced numerous challenges in bringing the drug to market, including setbacks in clinical trials and the need to raise funds through borrowing and share sales. Despite these obstacles, the company persisted and eventually saw success with Ohtuvayre’s approval in 2024.
One key aspect of protecting Ohtuvayre’s market exclusivity is its intellectual property, particularly its composition of matter patent. While this patent expired in 2020, other patents related to the drug’s formulation, manufacturing, and methods of use are still in effect. Additionally, Ohtuvayre’s use of a standard jet nebulizer device limits the scope for additional patent protections.
The FDA’s Orange Book lists several patents for Ohtuvayre, with the most critical one expiring in the mid-2030s. This formulation patent covers the technology necessary to maintain the drug’s stability in varying temperatures, making it a crucial piece of intellectual property for Merck to defend.
Analysts have noted that the strength of this specific patent may not be as robust as others for branded molecules, but the unique challenges of maintaining drug stability in an inhaled medicine make it essential. Even if generic competitors manage to invalidate patents after 2031, Merck’s acquisition of Verona Pharma could still prove to be a sound investment, particularly if Ohtuvayre reaches its projected peak revenue.
For Merck, Ohtuvayre represents a potential source of revenue diversification, helping to offset future financial losses when patents for its current top-selling drug, Keytruda, expire. This strategic move by Merck demonstrates its commitment to securing its position in the pharmaceutical market and ensuring a strong pipeline of innovative treatments for patients. Verona Pharma, a leading pharmaceutical company, is currently conducting phase 2 trials for the development of dry powder and pressurized “metered dose” inhalers. These trials are a crucial step in the company’s efforts to establish additional formulation or device patents, further solidifying its position in the market.
Dry powder inhalers and pressurized metered dose inhalers are innovative delivery systems that allow for precise and effective administration of medication directly to the lungs. By studying these technologies in phase 2 trials, Verona Pharma is positioning itself as a key player in the development of advanced inhalation therapies.
The company’s focus on these inhaler technologies reflects its commitment to improving patient outcomes and advancing the field of respiratory medicine. By investing in research and development, Verona Pharma is able to stay ahead of the curve and offer cutting-edge solutions to patients with respiratory conditions.
In addition to the clinical benefits of these inhaler technologies, Verona Pharma stands to gain valuable intellectual property through the establishment of new patents. This not only protects the company’s investment in research and development but also ensures that it remains a leader in the field of respiratory medicine.
As Verona Pharma continues to progress through phase 2 trials, the company is laying the groundwork for future success. With a focus on innovation and a dedication to improving patient care, Verona Pharma is poised to make a significant impact in the world of respiratory medicine.
