The Patent Cliff Reemerges: Can Biopharmaceutical Leaders Innovate Quickly Enough to Maintain Their Edge?

The biopharmaceutical sector is entering a renewed phase of loss of exclusivity (LOE), echoing the “patent cliff” experienced in the early 2010s. As patents for high-value treatments like Tagrisso (osimertinib), Calquence (acalabrutinib), and Olaparib (olaparib) approach expiration, industry leaders must respond with urgency. This wave of drug loss of exclusivity affects not only established markets like the United States but also rapidly evolving regions such as India and Japan (India loss of exclusivity analysis, Japan loss of exclusivity analysis). Companies must now adopt more sophisticated loss of exclusivity strategies to protect revenues and remain competitive.

Merck: Leveraging Pipeline Strength for Long-Term Stability

Merck’s flagship immunotherapy Keytruda (pembrolizumab) is nearing the end of its market exclusivity, prompting critical attention to when Keytruda loses exclusivity. In response, Merck is pursuing a pipeline-focused strategy, channeling investments into oncology and immunology. With the introduction of Cobenfy and progress in next-generation checkpoint inhibitors and vaccine platforms, Merck is demonstrating a robust, forward-looking medical strategy for loss of exclusivity and long-term asset sustainability.

AstraZeneca: Strategic Diversification Through Scientific Innovation

Facing upcoming LOEs for Calquence (acalabrutinib) and Tagrisso (osimertinib), AstraZeneca is prioritizing diversification via research-driven development and strategic collaborations. The advancement of drugs such as Enhertu (trastuzumab deruxtecan), including a new subcutaneous formulation, underlines AstraZeneca’s loss of exclusivity pharma strategy rooted in science-led expansion. Strategic mergers and acquisitions, along with a fortified pipeline, are softening the pharma loss of exclusivity impact and preparing the company for a new generation of therapies.
