DISCOVER 2 (ACR20): CONTINUED IMPROVEMENT IN JOINT SYMPTOMS# AT 2 YEARS

View Study Design

IN DISCOVER 1:

Week 24 (primary endpoint): 52% of patients receiving TREMFYA® q8w (66/127) achieved an ACR20 response vs 22% of patients receiving placebo (28/126) (P<0.0001)1,2,6‡§

Week 16: 52% of patients receiving TREMFYA® q8w (66/127) achieved an ACR20 response vs 25% of patients receiving placebo (32/126) (P<0.0001)1,2‡§

Week 52 (NRI post hoc analysis): 60% of patients receiving TREMFYA® q8w (76/127) achieved an ACR20 response1,7‡§||††

ACR20 response in DISCOVER 1 and DISCOVER 2 at Week 16 was not part of the sequential testing procedure but was prespecified to be tested upon achieving statistical significance for ACR20 at Week 24.

NRI=nonresponder imputation.

*Year 2 represents Week 100.

The same patients may not have responded at each time point.

Through Week 24, patients were considered to be nonresponders after meeting treatment failure criteria: discontinued study agent for any reason, terminated study participation for any reason, initiated or increased the dose of disease-modifying antirheumatic drugs (DMARDs) or oral corticosteroids over baseline for PsA, or initiated protocol-prohibited medications/therapies for PsA. After Week 24, treatment failure rules were not applied.

§Patients with missing data were considered nonresponders.

||After Week 24, patients and doctors knew that all patients were on TREMFYA® (open label with a blinded dosing interval), which may have affected the results.

The DISCOVER 2 prespecified as-observed analysis from Weeks 24 to 100 is not shown.

*The same patients may not have responded at each time point.

Through Week 24, patients were considered to be nonresponders after meeting treatment failure criteria: discontinued study agent for any reason, terminated study participation for any reason, initiated or increased the dose of disease-modifying antirheumatic drugs (DMARDs) or oral corticosteroids over baseline for PsA, or initiated protocol-prohibited medications/therapies for PsA.
All the efficacy analyses through Week 24 were based on composite estimate, and missing data were considered nonresponders.

IN DISCOVER 1:

Week 24 (major secondary endpoint): 30% of patients receiving TREMFYA® q8w (38/127) achieved an ACR50 response compared with 9% of patients receiving placebo (11/126) (P<0.0001)1,2,6‡§
