Abstract

Background The PREDICT trial (NCT01255761) compared the patient-reported Routine Assessment of Patient Index Data (RAPID3) and the investigator-based Clinical Disease Activity Index (CDAI) tools in US rheumatoid arthritis (RA) patients (pts) receiving certolizumab pegol (CZP).1,2 The validated RA-specific Work Productivity Survey (WPS)3 was used to assess the impact of arthritis on pt productivity within and outside the home over the previous month.

Objectives To investigate the effect of CZP on workplace and household productivity and social participation in US RA pts with and without prior anti-TNF exposure in the PREDICT trial.

Methods Pts received CZP standard dosing regimen (400mg at Wks 0, 2, 4 [loading dose], then 200mg Q2W). The impact of RA on workplace and household productivity and daily activities was assessed by the WPS (administered Q4W until Wk24 and Q8W afterwards), stratified by pts with and without prior anti-TNF exposure. Mean WPS responses (LOCF) in the full analysis set (FAS) are summarized descriptively over 52 wks.

Results 733 pts were randomized; over half (55.5%) were prior anti-TNF failures. At baseline (BL), 38.8% and 49.4% of pts with and without prior anti-TNF exposure were employed outside the home, respectively. A high burden of RA on workplace and household productivity and social participation at BL was reported in pts with and without prior anti-TNF exposure, with on average >6 working days (anti-TNF naïve pts: mean 1.1 work days missed and 4.9 days with reduced productivity/month; prior anti-TNF pts: mean 1.8 work days missed and 6.5 days with reduced productivity/month) and >14 days of household work affected per month because of RA (anti-TNF naïve pts: mean 7.5 household work days missed and 7.4 days with reduced productivity/month; prior anti-TNF pts: mean 9.6 household work days missed and 7.8 days with reduced productivity/month; Table). Improvements were observed as early as Wk4 in both prior anti-TNF and anti-TNF naïve pts and were maintained through to Wk52. By Wk4, employed pts reported reductions in workplace absenteeism and presenteeism, as well as in the level of RA interference with work productivity (Table). Substantial improvements over time in both prior anti-TNF and anti-TNF naïve pts were also observed in household productivity and social participation.

Conclusions In RA pts initiating CZP, there were similar improvements between those with and without prior anti-TNF exposure in workplace, household productivity and social participation. These improvements were observed as early as Wk4 and maintained through Wk52.
