ACR20 Response Rate

The tofacitinib clinical development programme to assess efficacy and safety included 2 multicentre, randomised, double-blind, placebo-controlled, confirmatory trials in 816 patients 18 years of age and older (PsA-I and PsA-II).1

Although other doses have been studied, the recommended dose of tofacitinib is 5 mg BID. Tofacitinib 10 mg BID is not recommended for the treatment of PsA.

The PsA-I study was a 12-month clinical trial conducted in 422 patients who had an inadequate response to a nonbiologic DMARD (67% and 33% were IRs to 1 nonbiologic DMARD and ≥2 nonbiologic DMARDs, respectively) and who were naïve to treatment with a TNF blocker. 

The PsA-II study was a 6-month clinical trial conducted in 394 patients who had an inadequate response to at least 1 approved TNF blocker (66%, 19% and 15% were IRs to 1 TNF blocker, 2 TNF blockers and ≥3 TNF blockers, respectively).

Example

    

Subjects with missing data were treated as non-responders. 
*Subjects received 1 concomitant nonbiologic DMARD.  
N is the number of randomised and treated patients.    

    

​​​​​​The percentage of ACR20 responders by visit for the PsA-I study is shown in the figure below. Similar responses were observed in the PsA-II study. In both the studies, improvements in the ACR20 response on tofacitinib were observed at the first visit after baseline (Week 2).
