A new formulary exclusion battle is happening in specialty drugs…and PBMs will be profiting.
Just before Christmas, Express Scripts made AbbVie’s new Viekira Pak the exclusive option for genotype 1 hepatitis C patients covered by its national preferred formulary. This week, CVS/Caremark made Sovaldi and Harvoni (both from Gilead Sciences) the exclusive options for patients with hepatitis C.
I estimate that these formulary moves, combined with specialty pharmacy dispensing, will allow the PBMs to earn as much as $2,600 to $3,100 per patient. Pretty, pretty, pretty good.
Within three years, the generic wave ends, and specialty drugs will become payers’ primary focus. Expect more formulary battles as specialty classes get crowded with multiple therapeutic alternatives.
