aThe annual drug cost only includes the cost of drug therapy based on the February 2017 wholesale acquisition cost and does not include any costs associated with administration or monitoring. The annual drug costs reported in this table were an average over 3 years of treatment, assuming 100% compliance to reduce the variation of some TIMs loading dosing schedule.
bThe average discount from the wholesale acquisition cost was calculated for each drug class by comparing the 4-quarter rolling averages of net prices and wholesale acquisition cost per unit.
ACR = American College of Rheumatology improvement criteria; cDMARD = conventional disease-modifying antirheumatic drug; SC = subcutaneous; TIM = targeted immune modulator; TSS = Total Sharp Score.
