Herceptin Company: Roche 2019 sales: $6.08 billion Projected 2026 sales: $2.08 billion Projected CAGR: -14% Used for: HER2-positive breast cancer, stomach cancer
Like Roche's other two top-selling oncology drugs, Avastin and Rituxan, breast cancer med Herceptin faced U.S. biosimilar challengers for the first time in 2019. Unlike Herceptin's portfolio mates, however, Roche may have found a path forward for the blockbuster med as part of a combo therapy.
Herceptin hit $6.08 billion in sales in 2019, but those peak sales will soon be a thing of the past. Evaluate Pharma forecast that Roche's drug will reach just $2.08 billion in sales in 2026 with copycats on the market.
But while Herceptin's solo days as one of pharma's top-selling drugs are likely coming to a close, a combination of Herceptin and another Roche drug could keep the therapy relevant for years to come.
