Even as many things change in the drug industry, at least one fact should stay the same in the coming years, according to analysts at EvaluatePharma. AbbVie's megablockbuster Humira will lead the world's drug sales charts in 2024, according to a new report, representing a record-breaking run that has lifted the company's fortunes along the way.

After generating sales of $18.9 billion last year, Humira will turn in $15.23 billion in 2024 sales, according to the analysts' new World Preview 2018, representing a 3% annual slip during the period. Jefferies analysts have predicted sales for the drug will peak at $20.9 billion next year.
Humira will still hold pharma's sales crown in that year, according to the report, followed by Merck's Keytruda at $12.69 billion, Celgene's Revlimid at $11.93 billion, Bristol-Myers Squibb's Opdivo at $11.25 billion and BMS and Pfizer's Eliquis at $10.54 billion. All told, worldwide prescription drug sales will reach $1.2 trillion in 2024, according to the group.
Humira's performance will come in part thanks to two settlements the drugmaker has reached with biosim developers. Under agreements with Amgen and Samsung Bioepis, biosims from those developers won't launch in the U.S. until 2023. Both deals make it less likely another biosim player could enter the market and challenge AbbVie's drug. Price hikes will also play a role, as Humira's price has more than doubled over the past 5 years.
As the analysts note, Merck's checkpoint inhibitor Keytruda will overtake Bristol-Myers' Opdivo in the oncology space, churning ahead at 19% annual growth through 2024. Rounding out the top 10 are Johnson & Johnson and AbbVie's Imbruvica, Pfizer's Ibrance, Sanofi's Dupixent, Regeneron and Bayer's Eylea and J&J's Stelara.
