The net prices that health plans paid for medicines — after subtracting rebates, discounts, and fees — fell by 2.8% in last year’s fourth quarter, the largest decline ever measured by SSR Health, a research firm that tracks the pharmaceutical industry and its pricing trends.
A key reason for the big drop — which dwarfed the 0.4% decline seen at the same time a year earlier — was pricing pressure on the Humira treatment for rheumatoid arthritis and psoriasis. Over the past year, nine biosimilar versions of the medicine were launched by other companies seeking favorable placement on formularies, the lists of drugs for which health insurance coverage is available.
As these companies battled to win placement, the Humira net price fell to roughly $29,800 at the end of last year from $48,000 at the end of 2022, a nearly 38% drop, the SSR analysis found. In fact, the entire category of rheumatoid arthritis medicines saw a 30% decline in annual net pricing, the largest such drop among all type of drugs. Meanwhile, net prices for psoriasis treatments fell nearly 10%.
