What are orphan drugs and why are they important?

Orphan drugs are treatments for rare diseases affecting fewer than 200,000 people. They're important because they address unmet medical needs and often receive special regulatory incentives like market exclusivity, making them valuable for both patients and investors.

Why do FDA rejections benefit existing drug companies?

When the FDA rejects a new treatment, it removes competition for companies with already-approved drugs. This strengthens their market position, protects their pricing power, and extends the time they can operate without direct competitors.

What does market exclusivity mean for pharmaceutical stocks?

Market exclusivity means a company has the sole right to sell a particular treatment for a specific period. This protection allows them to set premium prices without competition, leading to higher profit margins and more predictable revenue streams.

How do high regulatory barriers protect these investments?

The complex and expensive process of getting drugs approved creates a protective moat around successful companies. New competitors must invest years and hundreds of millions in clinical trials with no guarantee of success, making it difficult to challenge established players.

What makes rare disease treatments different from regular pharmaceuticals?

Rare disease treatments serve smaller patient populations but face less competition and can command higher prices. They often receive faster regulatory review and longer exclusivity periods, creating more stable and profitable business models than mass-market drugs.
