Long-term safety and efficacy of upadacitinib versus adalimumab in patients with rheumatoid arthritis: 5-year data from the phase 3, randomised SELECT-COMPARE study.

To assess the safety and efficacy of upadacitinib versus adalimumab from SELECT-COMPARE over 5 years. Patients with rheumatoid arthritis and inadequate response to methotrexate were randomised to receive upadacitinib 15 mg once daily, placebo or adalimumab 40 mg every other week, all with concomitant methotrexate. By week 26, patients with insufficient response to randomised treatment were rescued; patients remaining on placebo switched to upadacitinib. Patients completing the 48-week double-blind period could enter a long-term extension. Safety and efficacy were assessed through week 264, with radiographic progression analysed through week 192. Safety was assessed by treatment-emergent adverse events (TEAEs). Efficacy was analysed by randomised group (non-responder imputation (NRI)) or treatment sequence (as observed). Rates of TEAEs were generally similar with upadacitinib versus adalimumab, although numerically higher rates of herpes zoster, lymphopenia, creatine phosphokinase elevation, hepatic disorder and non-melanoma skin cancer were reported with upadacitinib. Numerically greater proportions of patients randomised to upadacitinib versus adalimumab achieved clinical responses (NRI); Clinical Disease Activity Index remission (≤2.8) and Disease Activity Score based on C reactive protein <2.6 were achieved by 24.6% vs 18.7% (nominal p=0.042) and 31.8% vs 23.2% (nominal p=0.006), respectively. Radiographic progression was numerically lower with continuous upadacitinib versus adalimumab at week 192. The safety profile of upadacitinib through 5 years was consistent with the known safety profile of upadacitinib, with no new safety risks. Clinical responses were numerically higher with upadacitinib versus adalimumab at 5 years. Upadacitinib demonstrates a favourable benefit-risk profile for long-term rheumatoid arthritis treatment.

Efficacy and safety of upadacitinib in patients with rheumatoid arthritis and inadequate response or intolerance to biological treatments: results through 5 years from the SELECT-BEYOND study.

To evaluate the efficacy and safety of upadacitinib over 5 years among patients with rheumatoid arthritis (RA) in a long-term extension (LTE) of the SELECT-BEYOND phase 3 trial. Patients refractory to ≥1 biological disease-modifying antirheumatic drug (DMARD) received upadacitinib 15 mg or 30 mg once daily or placebo, in combination with background conventional synthetic DMARD(s). At week 12, patients randomised to placebo were switched to upadacitinib 15 mg or 30 mg. All patients who completed the week 24 visit could enter the LTE for up to 5 years. Efficacy was analysed as observed and by non-responder imputation through week 260. Treatment-emergent adverse events per 100 patient-years were summarised over 5 years. Of the 498 patients randomised, 418 (84%) completed week 24 and entered the LTE. Of those who remained in the trial (n=80, upadacitinib 15 mg; n=81, upadacitinib 30 mg), 36%/36% and 81%/77% randomised to upadacitinib 15/30 mg were in Clinical Disease Activity Index (CDAI) remission or low disease activity at week 260, respectively (as observed). Approximately 47% of all patients who began in high disease activity demonstrated a CDAI improvement >12 at week 260 with upadacitinib 15/30 mg. Functional and pain-related outcomes also showed comparable improvements with both doses. Numerically higher rates of anaemia, herpes zoster and creatine phosphokinase elevation were observed with upadacitinib 30 mg vs 15 mg. No new safety issues were identified. Upadacitinib 15/30 mg continued to be effective in treating clinical and functional outcomes in patients with RA. The safety profile observed over 5 years was consistent with earlier study-specific and integrated assessments of upadacitinib treatment.

Efficacy and safety of upadacitinib in patients with active ankylosing spondylitis refractory to biologic therapy: 2-year clinical and radiographic results from the open-label extension of the SELECT-AXIS 2 study.

The efficacy and safety of upadacitinib in patients with ankylosing spondylitis (AS) and inadequate response/intolerance to biologic disease-modifying antirheumatic drugs (bDMARD-IR) were evaluated through 1 year in the SELECT-AXIS 2 study. Here, we assess 2-year efficacy, safety, and imaging outcomes in SELECT-AXIS 2. Patients who received continuous upadacitinib, and those who switched from placebo to upadacitinib at week 14, could enter the open-label extension (OLE). Efficacy endpoints included Assessment of SpondyloArthritis international Society (ASAS) and Axial Spondyloarthritis Disease Activity Score (ASDAS) responses, and changes from baseline in measures of disease activity, back pain, function, and quality of life. Radiographic progression was evaluated using the modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS). As observed (AO) and AO with non-responder imputation (AO-NRI) analyses were used for binary endpoints; AO with mixed-effects model for repeated measures (AO-MMRM) for continuous endpoints; and AO-analysis of covariance for mSASSS. Treatment-emergent adverse events (TEAEs) in patients receiving ≥ 1 upadacitinib dose through week 104 are presented as events (E)/100 patient-years (PY). Subgroup analyses were performed by prior tumor necrosis factor/interleukin-17 inhibitor exposure and bDMARD lack of efficacy/intolerance. Of 420 patients who entered the bDMARD-IR AS study, 409 entered the OLE, and 331 (continuous upadacitinib, n = 163; placebo to upadacitinib, n = 168) completed week 104. Improvements in efficacy measures were sustained through the OLE, with similar response rates between the continuous upadacitinib and placebo to upadacitinib groups at week 104. At week 104, 64.9% and 61.7% of patients, respectively, had achieved ASAS 40% response (AO-NRI). Mean changes from baseline were similar between the two groups at week 104 across measures (ASDAS: -2.1 and -2.0; total back pain: -4.9 and -4.6, respectively; AO-MMRM). Over 93.0% of patients showed no radiographic progression (mSASSS mean change from baseline < 2) at week 104. The overall TEAE rate was 165.2 E/100 PY, with low rates of major adverse cardiovascular and venous thromboembolic events (0.3 E/100 PY each). Upadacitinib efficacy, including very low rates of radiographic progression, was demonstrated through 104 weeks in treatment-refractory patients with active AS. Treatment was well tolerated, with no newly identified safety signals. NCT04169373.

Long-term sustainability of response to upadacitinib among patients with active rheumatoid arthritis refractory to biological treatments: results up to 5 years from SELECT-BEYOND.

To evaluate the long-term sustainability of response to the Janus kinase inhibitor upadacitinib among patients with rheumatoid arthritis and an inadequate response or intolerance to biological disease-modifying antirheumatic drugs (bDMARD-IR) in the SELECT-BEYOND phase 3 trial. Patients on background conventional synthetic DMARDs (csDMARDs) were treated once daily with upadacitinib 15 mg or placebo. Patients who completed the week 24 visit could enter a long-term extension of up to 5 years. The sustainability of response was assessed based on achievement of Clinical Disease Activity Index (CDAI), Simplified Disease Activity Index (SDAI) and Disease Activity Score 28-joint count using C-reactive protein (DAS28 (CRP)) targets and evaluated up to week 260 in all patients receiving the approved upadacitinib 15 mg dose, including those randomised to upadacitinib 15 mg and those who switched from placebo to upadacitinib 15 mg at week 12. In this bDMARD-IR population, 45% (n=104/229) and 79% (n=172/219) of patients treated with upadacitinib 15 mg plus background csDMARD(s) achieved CDAI remission or CDAI low disease activity (LDA) at any point during the 5-year study, respectively. Of those who achieved CDAI remission/LDA, 25%/43% maintained their initial response through 240 weeks of follow-up after first achieving response. Most patients who lost remission or LDA were able to recapture that response by the cut-off date. Similar overall results were observed for SDAI and DAS28 (CRP). No strong predictors of response were identified. Over three-quarters of bDMARD-IR patients achieved CDAI LDA with upadacitinib, and almost half of those maintained LDA through 240 weeks of follow-up. Remission was achieved by nearly half of all patients and maintained in approximately a quarter of those achieving remission. NCT02706847.

Development of rheumatoid arthritis after methotrexate in anticitrullinated protein antibody-negative people with clinically suspect arthralgia at risk of rheumatoid arthritis: 4-year data from the TREAT EARLIER trial.

Prevention of rheumatoid arthritis has become a definitive target. However, whether prevention of anti-citrullinated protein antibody (ACPA)-negative rheumatoid arthritis is possible is still unknown. We aimed to assess the efficacy of a 1-year course of methotrexate on the development of rheumatoid arthritis in ACPA-negative people with clinically suspect arthralgia and predicted increased risk of rheumatoid arthritis. For this follow-up analysis, we used 4-year data from the TREAT EARLIER trial, a randomised, double-blind, placebo-controlled, proof-of-concept trial conducted in the southwest region of the Netherlands from which we analysed data collected between April 16, 2015, and Sept 11, 2023. ACPA-positive and ACPA-negative adults aged 18 years or older with arthralgia and subclinical joint inflammation who were at risk of developing rheumatoid arthritis were eligible for enrolment. For TREAT EARLIER, participants were randomly assigned (1:1) to active treatment or placebo. Active treatment consisted of a single intramuscular glucocorticoid injection (120 mg of methylprednisolone) upon inclusion, then a 1-year course of methotrexate. Placebo consisted of a single placebo injection followed by a 1-year course of placebo tablets. Trial visits occurred every 4 months during the first 2 years, at which clinical and questionnaire data were collected. Total follow-up was 4 years. For this analysis, participants were stratified via a prediction model into low risk, increased risk, and high risk of developing persistent, clinically apparent inflammatory arthritis. The primary outcome was development of rheumatoid arthritis, defined as the presence of clinically apparent inflammatory arthritis and clinical diagnosis of rheumatoid arthritis, and was assessed in all TREAT EARLIER participants. Severity of subclinical joint inflammation, physical functioning, and grip strength in ACPA-negative participants was studied in each risk group over a period of 2 years. 901 people with clinically suspect arthralgia were assessed for eligibility and 236 were enrolled in TREAT EARLIER. All 236 participants were included in the intention-to-treat analysis and 217 (92%) completed 4-year follow-up. 154 (65%) of 236 participants were women and 82 (35%) were men, 182 (77%) were ACPA-negative and 54 (23%) were ACPA-positive. Of the 182 randomly assigned ACPA-negative participants, none were predicted to be at high risk of developing persistent, clinically apparent inflammatory arthritis, 66 (36%) at increased risk, and 116 (64%) at low risk. Of the 54 ACPA-positive participants, 24 (44%) were predicted to be at high risk, 30 (56%) at increased risk, and none at low risk. After 4 years, 52 (22%) of 236 participants had developed the primary outcome of rheumatoid arthritis (25 [21%] of 119 in the treatment group and 27 [23%] of 117 in the placebo group). Of the 66 ACPA-negative participants predicted to be at increased risk, three (9%) of 35 in the treatment group developed the primary outcome compared with nine (29%) of 31 in the placebo group (hazard ratio 0·27, 95% CI 0·07-0·99; p=0·034). Of the 116 ACPA-negative participants predicted to be at low risk, four (8%) of 53 in the treatment group met the primary outcome compared with six (10%) of 63 in the placebo group (0·79, 0·22-2·80; p=0·71). Thus, after risk stratification, a 1-year course of methotrexate was associated with a reduced rate of development of ACPA-negative rheumatoid arthritis in participants with predicted increased risk of developing the disease. Subclinical joint inflammation, physical functioning, and grip strength persistently improved upon treatment in ACPA-negative participants with increased risk of developing rheumatoid arthritis, but not in those with low risk. Risk stratification can be helpful in trials of ACPA-negative people with clinically suspect arthralgia to identify participants who could benefit from treatment to prevent development of rheumatoid arthritis.
