- Patent Protection Extended: Pfizer has reached a settlement with Hikma, Cipla, and Dexcel to extend the patent protection for Vyndamax until June 2031, providing the company with additional time to develop new blockbuster drugs, thereby enhancing its market competitiveness.
- Revenue Growth Support: Vyndamax and its related drugs generated $6.3 billion in revenue for Pfizer in 2025, reflecting a 17% increase and accounting for 10% of total revenue, indicating that Pfizer can maintain revenue stability despite slowing COVID vaccine sales.
