AbbVie's Upadacitinib (ABT-494) Meets All Primary and Ranked Secondary Endpoints in Second Phase 3 Study in Rheumatoid Arthritis
- SELECT-BEYOND, the second study in the robust SELECT program, demonstrated positive results with both doses (15 mg and 30 mg once-daily) meeting the primary endpoints in a difficult-to-treat patient population, over half of whom had previously been treated with two or more biologics(1)
- Both doses achieved low disease activity in over 40 percent of patients at week 12 and over 50 percent of patients at week 24(1)
- The safety profile of upadacitinib was consistent with previously reported studies, with no new safety signals detected(1-4)
- Upadacitinib, an oral agent engineered by AbbVie to selectively inhibit JAK1, is being studied as a once-daily therapy in rheumatoid arthritis in the SELECT program and across multiple immune-mediated diseases(5-12)
NORTH CHICAGO, Ill., Sept. 11, 2017 /PRNewswire/ -- AbbVie (NYSE: ABBV), a global research and development based biopharmaceutical company, today announced positive top-line results from the Phase 3 SELECT-BEYOND clinical trial evaluating upadacitinib (ABT-494), an investigational oral JAK1-selective inhibitor, in patients with moderate to severe rheumatoid arthritis (RA) who did not adequately respond or were intolerant to treatment with biologic DMARDs (bDMARDs).1 Results showed that after 12 weeks of treatment, both once-daily doses of upadacitinib (15 mg and 30 mg) met the study's primary endpoints of ACR20* and low disease activity (LDA)**.1 All ranked secondary endpoints were also achieved with both doses.1 Upadacitinib is not approved by regulatory authorities and safety and efficacy have not been established.
"We are very pleased with the positive results for upadacitinib in the SELECT-BEYOND trial. Particularly exciting is the proportion of patients who achieved clinical remission by week 12 and 24, despite having inadequate responses with previous biologic therapies," said Michael Severino, M.D., executive vice president, research and development and chief scientific officer, AbbVie. "Together with previously reported results from SELECT-NEXT, these data further support the potential for upadacitinib to be a meaningful treatment option for rheumatoid arthritis patients. We continue to build upon our leadership in immunology as we advance the development program for upadacitinib across a broad range of immune-mediated diseases."
Rheumatoid arthritis is a chronic and debilitating disease that affects an estimated 23.7 million people worldwide.13 Despite progress in the treatment of RA, many patients still do not achieve remission or low disease activity targets.14
"This trial strengthens previous upadacitinib study results in patients who do not respond adequately to biologic therapies. For these patients, therapeutic options are limited, and the unmet medical need is high," said Mark Genovese, M.D., professor of immunology and rheumatology, Stanford University and an investigator in the study. "More than half of upadacitinib patients achieved low disease activity by week 24. These results in difficult-to-treat patients further demonstrate the potential of upadacitinib to be an important new treatment option in rheumatoid arthritis."
Results at week 12 showed that of patients receiving an oral once-daily dose of 15 mg or 30 mg upadacitinib, ACR20/50/70* response was achieved in 65/34/12 percent of patients with the 15 mg dose, respectively, and 56/36/23 percent with the 30 mg dose, respectively, compared to 28/12/7 percent in the placebo group.1 These results were statistically significant compared to placebo (p<0.001) for all comparisons except ACR70 for the 15 mg dose.1
Additionally, a significantly higher proportion of upadacitinib patients in both doses achieved LDA and clinical remission targets at week 12 compared to patients receiving placebo (p<0.001).1 Low disease activity was achieved by 43 percent and 42 percent of patients in the 15 mg and 30 mg groups, respectively, compared to 14 percent of patients receiving placebo.1 Clinical remission was achieved by 29 percent and 24 percent of patients in the 15 mg and 30 mg groups, respectively, compared to 10 percent of patients receiving placebo.1
Results continued to be encouraging through week 24.1 Of patients treated with upadacitinib from study entry, ACR20/50/70* response was achieved in 62/43/22 percent of patients with the 15 mg dose and 59/43/24 percent with the 30 mg dose at week 24.1 Low disease activity was achieved by 52 percent of patients receiving either dose of upadacitinib.1 Clinical remission was achieved by 32 percent and 35 percent of patients in the 15 mg and 30 mg groups, respectively.1 Comparisons to placebo cannot be made at week 24, since all placebo patients received either upadacitinib 15 mg or 30 mg beginning at week 12.1

Not all ranked and non-ranked secondary endpoints shown. Statistical comparisons to placebo were not conducted for week 24 values since no patients received placebo beyond week 12.

In this study, the safety profile of upadacitinib was consistent with previously reported Phase 2 trials and the Phase 3 SELECT-NEXT clinical trial.1-4 No new safety signals were detected.1 During the placebo-controlled period, serious adverse events occurred in 5/7/0 percent of patients in the 15 mg/30 mg/placebo groups, respectively.1 There were two deaths reported during the study.1 One was a patient in the 15 mg dose group with cause of death unknown.1 The second was a patient in the 30 mg dose group who presented with fever and diarrhea, subsequent heart failure and presumed pulmonary embolism (PE) during hospitalization.1 Inclusive of the case mentioned above, a total of two cases of PE and no deep vein thrombosis (DVT) were reported during the placebo-controlled period. In the previously reported Phase 3 SELECT-NEXT trial, no cases of DVT or PE occurred.15 Across the SELECT RA program, including both, the placebo-controlled and extension periods, the rate of DVT and PE remains consistent with the background rate for the RA patient population.1,4,15-16
Further results of SELECT-BEYOND, the second of six studies in the SELECT RA clinical trial program, will be presented at a future medical meeting and published in a peer-reviewed publication.
AbbVie is continuing to evaluate the potential of upadacitinib across several immune-mediated conditions. Phase 3 trials of upadacitinib in psoriatic arthritis are ongoing, and it is also being investigated to treat Crohn's disease, ulcerative colitis, ankylosing spondylitis and atopic dermatitis.7-12
About SELECT-BEYOND1
SELECT-BEYOND is a Phase 3, multicenter, randomized, double-blind, placebo-controlled study designed to evaluate the safety and efficacy of two once-daily doses (15 mg and 30 mg) of upadacitinib in adult patients with moderate to severe rheumatoid arthritis who are on a stable dose of conventional synthetic DMARDs (csDMARDs) and have had an inadequate response or intolerance to bDMARDs. The primary endpoints included the percentage of subjects achieving an ACR20 response and low disease activity (LDA) after 12 weeks of treatment. Secondary endpoints included proportion of patients achieving ACR50 and ACR70 response at week 12. More information on this trial can be found at www.clinicaltrials.gov (NCT02706847).
