PSORIATIC ARTHRITIS
SELECT-PsA 1
ACR20 for RINVOQ vs placebo at Week 12 was a primary, multiplicity-controlled endpoint.
DATA LIMITATIONS: Data not labelled as a primary or ranked secondary endpoint were prespecified non-ranked endpoints not controlled for multiplicity with nominal p-values; therefore, treatment differences could represent chance findings. No conclusions regarding these comparisons can be made.
Non-responder imputation: Patients dropping out of the study for any reason were considered non-responders.

SELECT-PsA 1: Inhibition of structural joint damage progression at Week 24 (linear extrapolation)1,2
Proportion of patients with no radiographic progression (mTSS change ≤0.5) was higher with RINVOQ vs placebo at Week 24 (96% vs 92%, nominal P≤0.05) and at Week 56† - (97% vs 89%, nominal p≤0.001)1,5

Subjects rescued at Week 16 were imputed as non-responders in the resolution of enthesitis and dactylitis at Week 24.

#RINVOQ 15 mg did not meet superiority vs adalimumab for ACR20 response, thus statistical significance vs placebo regarding proportion of patients achieving resolution of dactylitis could not be tested under the hierarchical analysis plan. Subjects rescued at Week 16 were imputed as non-responders in the resolution of enthesitis and dactylitis at Week 24.

SELECT-PsA 1: Minimal disease activity at Week 24 (NRI)2,6
*p≤0.001 vs placebo, comparison adjusted for multiplicity. Subjects rescued at Week 16 were imputed as non-responders in the MDA analysis. Minimal disease activity with RINVOQ vs placebo at Week 24 was a key ranked secondary, multiplicity-controlled endpoint. Non-responder imputation: Patients dropping out of the study for any reason were considered non-responders
†Minimal Disease Activity is achieved when meeting 5 of 7 criteria7
- Tender joint count ≤1
- Swollen joint count ≤1
- PASI ≤1 or BSA-PsO ≤3%
- Patient pain NRS ≤1.5
- Patient Global Disease Activity NRS ≤2
- HAQ-DI ≤0.5
- Tender entheseal points (LEI) ≤1
SELECT-PsA 1: A Phase 3 randomised, double-blind study assessing the efficacy and safety of RINVOQ, compared to placebo and adalimumab in PsA patients with an inadequate response or intolerance to at least one non-biologic DMARD.2
The approved dose of RINVOQ is 15mg QD. Upadacitinib 30mg QD is not an approved dose.
All subjects received x-rays of hands and feet at screening, Week 24, Week 56, Week 104, and Week 152. At Week 16, rescue therapy was offered to subjects classified as non-responders (defined as not achieving at least 20% improvement in TJC and SJC at both Week 12 and Week 16). At Week 24, all placebo subjects were switched to RINVOQ 15mg OD or upadacitinib 30mg OD (1:1 ratio) regardless of response.
Endpoints:
Primary endpoint: ACR20 response at Week 12 for RINVOQ vs placebo
Key secondary endpoints:
Statistically significantly greater improvement with RINVOQ vs placebo in:
- mTSS at Week 24
- Resolution of enthesitis at Week 24
- PASI75 response at Week 16
- sIGA 0/1 and >2 point improvement at Week 16
- MDA at week 24
- HAQ-DI at Week 12
- SF-36 PCS at Week 12
- FACIT-F at Week 12
