Business Strategy and Outlook
| Rachel Elfman |Vertex was once known for discovering Incivek, a blockbuster hepatitis C drug now overshadowed by a robust cystic fibrosis franchise with megablockbuster potential. The company's approved cystic fibrosis drugs are Kalydeco, Orkambi, Symdeko, and Trikafta, which will make Vertex eligible to treat about 90% of the CF population, assuming international and pediatric approvals. We expect Vertex to maintain its dominant position in CF, given the strong efficacy of its therapies, lengthy patents, and lack of competition, while developing pipeline candidates in other rare indications to spur growth.
