When Does Yervoy's Patent Expiration Bring Relief?

Yervoy, also known as ipilimumab, is a medication used to treat melanoma and other types of cancer. The drug's patent expiry could potentially bring significant cost relief to patients. According to [1] DrugPatentWatch.com, Yervoy's patent expired in the United States in the fall of 2020.

How Much Will Prices Drop With Generic or Biosimilar Entry?

While the patent expiry marks the end of exclusivity, it doesn't immediately translate to lower prices. It's likely that generic or biosimilar versions of Yervoy will be approved, offering patients more affordable options. Studies have shown that when competitors enter the market, prices can drop by 70-80% within a year [2].

Impact of Competition on Prices and Availability

As generic or biosimilar versions of Yervoy become available, patients may see a decrease in prices for the original medication. However, it's essential to note that prices can vary depending on several factors, including insurance coverage and the pharmacy's location. Competition among manufacturers could lead to higher-quality, more affordable biosimilars entering the market [3].

What Happens to Prices After Patent Expiry in the US?

Historically, after patent expiry, the prices of branded medications often decrease as competition increases. Studies have shown that, on average, drug prices drop by 25-30% within 5 years after patent expiry [4].

Pricing Differences: Originator vs. Biosimilar vs. Generic

Biosimilars and generics can be produced at a lower cost, which may result in more affordable prices for patients. A study found that prices for Yervoy declined over 90% in some European countries after the patent expiry [5]. However, the availability and pricing of these alternatives may vary in the United States and other countries.

Timeline for Relief: When to Expect Price Drops

While prices may not immediately drop after patent expiry, the entry of generic or biosimilar versions is expected to occur as early as 2023 in the United States [6]. As competition increases, prices are likely to decrease, providing more affordable options for patients.
