Rheumatoid arthritis

Disproportionate articular pain is a frequent phenomenon in rheumatoid arthritis and responds to treatment with sarilumab

Rheumatology (Oxford)Published Post hoc analysis of randomised controlled trials and open-label extensions

Authors' conclusion

About one-quarter of patients with RA experienced DP, which responded well to sarilumab.

Study context

Population
RA patients in phase 3 randomized controlled trials (RCTs) MOBILITY, TARGET and MONARCH and their open-label extensions (OLEs); DP defined as TJC28 − SJC28 ≥71,531 sarilumab 200 mg patients from RCTs
Comparison
Sarilumab 200 mg vs placebo or adalimumab 40 mg, in patients with and without disproportionate articular pain
  • Sarilumab 200 mgn = 1,531
Methodological detailspooled data from phase 3 RCTs (MOBILITY, TARGET, MONARCH)
  • Pooled data from phase 3 RCTs (MOBILITY, TARGET, MONARCH)

Primary result

As reported in the abstract

Prevalence of baseline disproportionate articular pain (DP)

Sarilumab 200 mg

23%

353 of 1531

Further findings

Low disease activity in RCTs

More sarilumab-treated patients achieved low disease activity vs comparators, regardless of baseline DP status

DP status in OLEs

Patients more likely to lose rather than gain DP status
