Despite 16 approvals in the last four years, just six biosimilars currently are being marketed stateside. The U.S. biosimilars market hasn’t progressed as anticipated, yet some experts are wondering whether the biologic follow-ons can redeem themselves with a breakout year in 2019.
The U.S. biosimilars market has a tough road ahead. The WAC list price differential between biosimilars and the originator drugs is hovering around 30%, on average, which likely isn’t speeding biosimilars’ adoption in the U.S. Rather than playing the long game and waiting for the U.S. landscape to become more attractive, some biosimilar manufacturers like Momenta are choosing to exit the market. And others like Pfizer have shuttered their preclinical biosimilar programs to focus their efforts elsewhere. On the flip side, the Trump administration has zeroed in on drug pricing and biosimilars as priorities—and, of course, the two are intertwined.
