Pricing Factors
- Patent status influences pricing; patent expiry for Entecavir was in 2022 in some jurisdictions.
- Generic entry reduces prices; generic versions are priced about 30-50% lower in markets like India and China.
- Insurance coverage and payer policies impact actual patient out-of-pocket costs.
What Are Price Trends and Projections?
Historical Trends (2018–2022)
- Steady prices in developed markets; slight decrease (~5%) due to market competition.
- Price erosion accelerates upon patent expiry and after generic entry.
- Patent expiration schemes, such as in the US (2022), enable generic manufacturers to introduce lower-cost versions.
