“We wish biosimilar competition would efficiently lower biologics prices to the socially optimal level of marginal economic cost,” wrote Bach and coauthors. “But, in this case, the ideological preference for competition needs to be put aside for a more effective, efficient, and economically justified approach of regulating biologics as natural monopolies.”

Fourteen parties have submitted comments on the guidance; in addition to other concerns with the document, including calls for clarification on the use of non-US comparator products and the potential for the waiver of bridging studies in the biosimilar development process, some drug makers called on the FDA to clarify issues associated with lot-to-lot variation and quality attributes.

The top 3 drugs in 2018 in the United States by spending were adalimumab, insulin glargine, and etanercept, according to a study in The American Journal of Health-System Pharmacy, which also predicted that drug spending will grow 4% to 6% this year.
