ABSTRACT
OBJECTIVE: To investigate the clinical response at week 52 in patients with ankylosing spondylitis (AS) who received secukinumab 300 vs 150 mg after inadequate response to 150 mg at week 16. METHODS: ASLeap (NCT03350815) was a randomized, double-blind, parallel-group, multicentre, phase 4 trial. After 16 weeks of open-label secukinumab 150 mg (Treatment Period 1), patients who did not achieve inactive disease (Ankylosing Spondylitis Disease Activity Score [ASDAS] <1.3) at both Weeks 12 and 16 were considered to have an inadequate response and were randomized 1:1 to receive secukinumab 300 or 150 mg every 4 weeks until week 52 (Treatment Period 2). The primary efficacy variable was achievement of ASDAS <1.3 at week 52 using week 16 as baseline. Safety was evaluated by the incidence of treatment-emergent adverse events through week 52. RESULTS: Of 322 patients treated with secukinumab in Treatment Period 1, 207 (64.3%) had inadequate response. Similar proportions of patients with inadequate response randomized to secukinumab 300 mg (n = 101) and 150 mg (n = 105) in Treatment Period 2 completed the study (83.8% and 84.3%, respectively). At week 52, 8.8% and 6.7% of patients receiving secukinumab 300 and 150 mg, respectively, achieved ASDAS <1.3. The incidence of treatment-emergent adverse events was similar in both groups through week 52. No new safety signals were observed. CONCLUSION: Patients with AS who did not achieve ASDAS <1.3 after receiving secukinumab 150 mg for 16 weeks experienced similar clinical response and safety through week 52 regardless of dose escalation.

ABSTRACT
INTRODUCTION: The aim of this work is to evaluate secukinumab vs. placebo in a challenging-to-treat and smaller US patient subpopulation of the international FUTURE 2-5 studies in patients with psoriatic arthritis (PsA). METHODS: Data were pooled from US patients enrolled in the phase 3 FUTURE 2-5 studies (NCT01752634, NCT01989468, NCT02294227, and NCT02404350). Patients received secukinumab 300 or 150 mg with subcutaneous loading dose, secukinumab 150 mg without subcutaneous loading dose, or placebo. Categorical efficacy and health-related quality-of-life (QoL) outcomes and safety were evaluated at week 16. Subgroup analyses were performed based on tumor necrosis factor inhibitor (TNFi) status and body mass index (BMI). For hypothesis generation, odds ratios (ORs) for American College of Rheumatology (ACR) 20/50/70 and Psoriasis Area and Severity Index (PASI) 75/90/100 responses by treatment were estimated using logistic regression without adjustment for multiple comparisons. RESULTS: Of 2148 international patients originally randomized, 279 US patients were included in this pooled analysis. Mean BMI was > 30 kg/m2 and 55.2% had prior TNFi treatment. ORs for ACR20/50/70 significantly favored patients receiving secukinumab 300 mg and 150 mg with loading dose vs. placebo (P < 0.05), but not those receiving secukinumab 150 mg without loading dose vs. placebo. For PASI75, ORs favored all secukinumab groups over placebo (P < 0.05); for PASI90 and PASI100, only the secukinumab 300-mg group was significantly favored over placebo (P < 0.05). CONCLUSIONS: In this challenging sub-population of US patients with PsA, secukinumab provided rapid improvements in disease activity and QoL. Patients with PsA and active psoriasis might benefit more from secukinumab 300 mg than 150 mg.
ABSTRACT
OBJECTIVE: To report 5-year efficacy and safety of upadacitinib (UPA) in rheumatoid arthritis (RA) from the phase III long-term extension (LTE) of SELECT-NEXT. METHODS: Patients on stable conventional synthetic disease-modifying antirheumatic drugs were randomized to UPA 15 mg once daily (QD), UPA 30 mg QD, or placebo for 12 weeks. Following this, placebo-randomized patients were switched to UPA 15 mg QD or UPA 30 mg QD in the LTE; UPA-randomized patients continued their original dose. Blinding remained until dose switching from UPA 30 mg QD to UPA 15 mg QD because of approval of UPA 15 mg QD; the earliest switch occurred at week 168. Efficacy (as observed) and treatment-emergent adverse events (TEAEs) are reported through 5 years. RESULTS: Overall, 611 (92%) randomized patients entered the LTE; 271 (44%) discontinued the study drug by 5 years, primarily because of adverse events (16%). Clinical outcomes improved or were maintained at 5 years; 51% and 43% of patients achieved Clinical Disease Activity Index remission and 75% and 66% achieved Disease Activity Score in 28 joints based on C-reactive protein < 2.6 among those initially randomized to UPA 15 mg QD and UPA 30 mg QD, respectively. Proportions of patients achieving ≥ 20%/50%/70% improvement in American College of Rheumatology criteria responses increased from week 60 through 5 years. Results were similar regardless of initial randomization to UPA or placebo. TEAEs, including TEAEs of special interest, were consistent with earlier analyses and other SELECT studies. Malignancies (excluding nonmelanoma skin cancer), major adverse cardiovascular events, and venous thromboembolic events were reported infrequently. No new safety signals were observed. CONCLUSION: The 5-year benefit-risk profile for UPA in RA remains favorable. (SELECT-NEXT; ClinicalTrials.gov: NCT02675426).

INTRODUCTION: Long-term therapeutic options providing durable response and tolerability are needed for psoriatic arthritis (PsA). The ongoing KEEPsAKE 2 trial is evaluating risankizumab treatment in patients with active PsA who previously had inadequate response/intolerance to ≥ 1 conventional synthetic disease-modifying antirheumatic drug (csDMARD-IR) and/or 1-2 biologic DMARDs (bDMARD-IR). Herein, we report results through 100 weeks of treatment. METHODS: KEEPsAKE 2 is a global phase 3 trial. Patients with active PsA were randomized 1:1 to double-blind subcutaneous risankizumab 150 mg or placebo (weeks 0, 4, and 16). At week 24, all patients received open-label risankizumab every 12 weeks until end of study. Efficacy endpoints included achieving ≥ 20% improvement in PsA symptoms using American College of Rheumatology criteria (ACR20), attaining minimal disease activity (MDA; meeting ≥ 5/7 criteria of low disease activity and extent), and improving in other measures. RESULTS: At the cutoff date, 345/443 (77.9%) patients were ongoing in the study. ACR20 was achieved in 57.1% and 52.5% of the continuous risankizumab and placebo/risankizumab cohorts, respectively, at week 100 and in 60.0% and 55.8%, respectively, at week 52. In week 52 responders, maintenance of ACR20 at week 100 was achieved in 74.8% (continuous risankizumab) and 78.7% (placebo/risankizumab) of patients. In the continuous risankizumab and placebo/risankizumab cohorts, respectively, MDA was achieved by 33.0% and 33.3% of patients at week 100 and by 27.2% and 33.8% at week 52. Among MDA responders at week 52, maintenance of MDA response was achieved by 83.6% and 73.0% of the continuous risankizumab and placebo/risankizumab cohorts, respectively. Risankizumab was well tolerated through week 100. CONCLUSIONS: Risankizumab demonstrated durable efficacy and tolerability through 100 weeks; most patients who achieved ACR20 and MDA responses at week 52 maintained this achievement through week 100. There were no new safety signals in patients who had csDMARD-IR and bDMARD-IR. TRIAL REGISTRATION: ClinicalTrials.gov NCT03671148.
Risankizumab, a biologic disease-modifying antirheumatic drug, helps control the body's immune system to reduce symptoms of psoriatic arthritis (a disease that inflames the joints of people who have the skin condition psoriasis). The ongoing KEEPsAKE 2 study is evaluating how well risankizumab works and how safe it is for treating adult patients with active psoriatic arthritis who previously experienced inadequate response to one or more specific types of disease-modifying anti-arthritis drugs. Patients were randomly assigned to receive either risankizumab or an inactive drug; after 24 weeks, all patients received risankizumab. At study week 100, 57% of patients who were assigned to receive continuous risankizumab since the start of the study experienced a 20% or more improvement in a measure of psoriatic arthritis symptoms using criteria established by the American College of Rheumatology (ACR20); a similar proportion of patients achieved a 20% improvement at both weeks 24 and 52. Similarly, 56% and 53% of patients who switched from inactive drug to risankizumab achieved ACR20 at weeks 52 and 100 (more than before switching to risankizumab at week 24). Minimal disease activity (MDA) was evaluated by assessing joint and skin symptoms, affected body surface area, pain, and physical function. At week 100, 33% of patients achieved MDA (both groups), which was similar to week 52. Most patients who achieved ACR20 or MDA at week 52 maintained responses at week 100. Improvements with risankizumab were seen in several other measures of treatment outcomes through week 100. Risankizumab was generally safe through 100 weeks.
ABSTRACT
Denosumab is a monoclonal antibody used to reduce risk of fractures in osteoporosis. ROSALIA was a multicenter, double-blind, randomized, integrated phase I/phase III study comparing the efficacy, pharmacokinetics (PK), pharmacodynamics (PD), immunogenicity, and safety of proposed biosimilar denosumab GP2411 with reference denosumab (REF-DMAb) (Prolia®; Amgen). Postmenopausal women with osteoporosis were randomized 1:1 to 2 60-mg doses of GP2411 or REF-DMAb, one at study start and one at week 26. At week 52, the REF-DMAb group was re-randomized 1:1 to a third dose of REF-DMAb or switch to GP2411. The primary efficacy endpoint was percentage change from baseline (%CfB) in LS-BMD at week 52. Secondary efficacy endpoints were %CfB in LS-BMD, FN-BMD, and TH-BMD at weeks 26 and 78 (and week 52 for FN-BMD and TH-BMD). Primary PK and PD endpoints were the area under the serum concentration-time curve extrapolated to infinity and maximum drug serum concentration at week 26, and the area under the effect-time curve of the %CfB in serum CTX at week 26. Secondary PK and PD endpoints included drug serum concentrations and %CfB in serum CTX and P1NP during the study period. Similar efficacy was demonstrated at week 52, with 95% CIs of the difference in %CfB in LS-BMD between treatment groups fully contained within prespecified equivalence margins. Similarity in PK and PD was demonstrated at week 26. Immunogenicity was similar between groups and was not impacted by treatment switch. The rate of new vertebral fractures was comparable. Treatment-emergent adverse events were comparable between groups (63.6% [GP2411/GP2411]; 76.0% [REF-DMAb/REF-DMAb]; 76.6% [REF-DMAb/GP2411]). In conclusion, ROSALIA showed similar efficacy, PK and PD, and comparable safety and immunogenicity of GP2411 to REF-DMAb in postmenopausal osteoporosis.
Denosumab is a biologic treatment that stops bone breakdown. This clinical trial evaluated how similar GP2411 (a denosumab biosimilar in development) is compared with European-approved reference denosumab in women with post-menopausal osteoporosis. Biosimilars are highly similar to the original treatment ('reference denosumab') and may have a lower price. 263 patients were randomly assigned to receive GP2411 and 264 to reference denosumab. Treatment was given at the study beginning, at Week 26 and at Week 52. 124 patients were re-assigned at Week 52 to test the effect of changing from reference denosumab to GP2411. The study showed similarity in how the body interacts with the treatments, what effects the treatment has (both measured over 26 weeks), and bone mineral density (measured over 78 weeks). Antibody responses to GP2411 were detected in similar proportions of patients on each treatment. Reported adverse events were similar between treatments before Week 52, and from Week 52 to 78, and <5% of patients experienced serious adverse events. A change of treatment from reference denosumab to GP2411 did not affect outcomes. These results showed similarity between GP2411 and reference denosumab in this population. In future, GP2411 may enable more patients to benefit from denosumab.

OBJECTIVES: Serum urate (SU) lowering with PEGylated uricases in gout can reduce flares and tophi. However, treatment-emergent anti-drug antibodies adversely affect safety and efficacy and the currently approved PEGylated uricase pegloticase requires twice-monthly infusions. Investigational SEL-212 therapy aims to promote uricase-specific tolerance via monthly sequential infusions of a proprietary rapamycin-containing nanoparticle (ImmTOR) and pegadricase. METHODS: COMPARE was a randomized, phase 2, open-label trial of SEL-212 vs pegloticase in adults with refractory gout. SEL-212 [ImmTOR (0.15 mg/kg) and pegadricase (0.2 mg/kg)] was infused monthly or pegloticase (8 mg) twice monthly for 6 months. The primary endpoint was the proportion of participants with SU <6 mg/dl for ≥80% of the time during 3 and 6 months. Secondary outcomes were mean SU, gout flares, number of tender and/or swollen joints and safety. RESULTS: During months 3 and 6 combined, numerically more participants achieved and maintained a SU <6 mg/dl for ≥80% of the time with SEL-212 vs pegloticase (53.0% vs 46.0%, P = 0.181). The percentage reductions in SU levels were statistically greater during months 3 and 6 with SEL-212 vs pegloticase (-73.79% and -47.96%, P = 0.0161). Reductions in gout flare incidence and number of tender and/or swollen joints were comparable between treatments. There were numerical differences between the most common treatment-related adverse events of interest with SEL-212 and pegloticase: gout flares (60.2% vs 50.6%), infections (25.3% vs 18.4%) and infusion-related reactions (15.7% vs 11.5%), respectively. Stomatitis (and related terms) was experienced by eight participants (9.6%) with SEL-212 and none with pegloticase. Stomatitis, a known event for rapamycin, was associated with ImmTOR only. CONCLUSIONS: SEL-212 efficacy and tolerability were comparable to pegloticase in refractory gout. This was associated with a substantial reduction in treatment burden with SEL-212 due to decreased infusion frequency vs pegloticase. CLINICAL TRIAL REGISTRATION: NCT03905512.

Purpose: Bimekizumab is a monoclonal IgG1 antibody that selectively inhibits interleukin (IL)-17F in addition to IL-17A, key drivers of chronic inflammation. Bimekizumab must be injected subcutaneously and so patients require self-injection options that meet their preferences. This study evaluated safe and effective self-injection of bimekizumab by patients with psoriatic arthritis using the 1 mL safety syringe (SSy) or the 1 mL auto-injector (AI). Patients and Methods: The DV0004 devices study (NCT04109976) was a sub-study of BE VITAL, a multicenter, open-label extension of BE OPTIMAL (NCT03895203) and BE COMPLETE (NCT03896581) in patients with active psoriatic arthritis. After receiving training, patients subcutaneously self-injected bimekizumab 160 mg at Baseline and Week 4. The primary and secondary endpoints were the proportion of patients self-injecting bimekizumab safely and effectively at Week 4 and Baseline, respectively. Patient self-injection experience was evaluated using the pain visual analog scale (VAS) and the Self-Injection Assessment Questionnaire (SIAQ). Results: Overall, 214 patients were randomized 1:1 at Baseline. All evaluable patients safely and effectively self-injected bimekizumab at Week 4 (SSy: n=105; AI: n=104) and Baseline (SSy: n=106; AI: n=106). Mean pain VAS scores were generally low at Week 4 (SSy: 11.0; AI: 11.4) and Baseline (SSy: 9.5; AI: 14.9). High mean pre- and post-injection SIAQ scores (≥6.7) were observed for both devices indicating a positive overall patient experience with self-injection. Self-injection was well tolerated with no reports of treatment-emergent adverse device effects (TEADEs), serious TEADEs or discontinuations due to TEADEs. Four non-device-related injection site reactions during the sub-study were reported in the parent study; all were mild, did not lead to discontinuation and resolved without treatment. All devices maintained their structural and functional integrity post-use. Conclusion: All patients self-injected subcutaneous bimekizumab safely and effectively using either device at Baseline and Week 4. Overall, patients reported a positive self-injection experience.
ABSTRACT
INTRODUCTION: This observational study evaluated response in patients with rheumatoid arthritis (RA) who switched from an interleukin-6 receptor inhibitor (IL-6Ri) to a Janus kinase inhibitor (JAKi) and vice versa. METHODS: Adult patients with RA, who initiated IL-6Ri or JAKi (following discontinuation of JAKi or IL-6Ri, respectively) during/after December 2012 and had a 6-month follow-up visit were enrolled. Clinical outcomes were evaluated at baseline and the follow-up visit. Continuous outcomes included Clinical Disease Activity Index (CDAI), Health Assessment Questionnaire (HAQ), pain, fatigue, tender joint count, swollen joint count, Physician Global Assessment (MDGA), Patient Global Assessment (PtGA), and morning stiffness duration. Categorical outcomes included the proportion of patients achieving CDAI low disease activity (LDA), remission, and minimal clinically important differences (MCIDs) for HAQ, pain, fatigue, MDGA, and PtGA. Continuous outcomes were summarized as mean changes from baseline, and categorical outcomes as response rates. Differences in the outcome measures between groups were evaluated using linear and logistic regression models. RESULTS: Between IL-6Ri (n = 100) and JAKi initiators (n = 129), no significant differences were noted for continuous outcomes. Within both groups, a significant proportion of patients achieved LDA, remission, and MCIDs for other measures, although the odds of achieving LDA were higher among IL-6Ri (vs. JAKi) initiators with moderate-to-severe disease (adjusted odds ratio: 3.30 [1.01, 10.78]). CONCLUSIONS: Patients with RA can achieve improvement in response when switching between IL-6Ri and JAKi. Although both therapies affect the IL-6 pathway, there are distinct mechanisms of action, which likely contribute to their clinical improvement, when reciprocally switched as follow-on treatments.
ABSTRACT
OBJECTIVES: To evaluate the safety, efficacy and response duration of four different dosing regimens of dazodalibep (DAZ), a non-antibody biological antagonist of CD40L, in patients with rheumatoid arthritis (RA). METHODS: This double-blind study included adult patients with moderate-to-severe active RA with a positive test for serum rheumatoid factor and/or anticitrullinated protein antibodies, an inadequate response to methotrexate, other conventional disease-modifying antirheumatic drugs or tumour necrosis factor-α inhibitors, and no prior treatment with B-cell depleting agents. Eligible participants were randomised equally to five groups receiving intravenous infusions of DAZ or placebo. The primary endpoint was the change from baseline in the Disease Activity Score-28 with C reactive protein (DAS28-CRP) at day 113. Participants were followed through day 309. RESULTS: The study randomised 78 eligible participants. The change from baseline in DAS28-CRP (least squares means±SE) at day 113 was significantly greater for all DAZ groups (-1.83±0.28 to -1.90±0.27; p<0.05) relative to PBO (-1.06±0.26); significant reductions in DAS28-CRP were also observed for all DAZ groups at day 309. The distribution of adverse events was generally balanced among DAZ and PBO groups (74% and 63%, respectively). There were four serious adverse events deemed by investigators to be unrelated to study medication. CONCLUSIONS: DAZ treatment for all dosage regimens significantly reduced DAS28-CRP at day 113 relative to PBO. The safety data suggest an acceptable safety and tolerability profile. Treatment effects at day 113 and the prolonged duration of responses after DAZ cessation support the use of longer dosing intervals. TRIAL REGISTRATION NUMBER: NCT04163991.

OBJECTIVE: Preliminary evidence suggests that vagus nerve stimulation (VNS) may have some benefit in patients with rheumatoid arthritis (RA); however, prior studies have been small and/or uncontrolled; this study aimed to address that gap. METHODS: This randomized, double-blind, sham-controlled trial enrolled patients aged 18 to 75 years with active RA who had failed conventional synthetic disease-modifying antirheumatic drugs (DMARDs) and were naïve to biologic and/or targeted synthetic DMARDs. All patients received an auricular vagus nerve stimulator and were randomized 1:1 to active stimulation or sham. The primary endpoint was the proportion of patients achieving 20% improvement in American College of Rheumatology criteria (ACR20) at week 12. Secondary endpoints included mean changes in disease activity score of 28 joints with C-reactive protein (DAS28-CRP) and Health Assessment Questionnaire-Disability Index (HAQ-DI). RESULTS: A total of 113 patients (mean age 54 years; 82% female) enrolled, and 101 patients (89.4%) completed week 12. ACR20 response at week 12 was 25.0% for active stimulation versus 26.9% for sham (difference vs. sham, -1.9; 95% CI, -18.8, 14.9, P = 0.823). The least square mean ± SE change in DAS28-CRP was -0.95 ± 0.16 for active stimulation and -0.66 ± 0.16 for sham (P = 0.201); in HAQ-DI it was -0.19 ± 0.06 for active stimulation and -0.02 ± 0.06 for sham (P = 0.044). Adverse events occurred in 17 patients (15%); all were mild or moderate. CONCLUSION: Auricular VNS did not meaningfully improve RA disease activity. If VNS with other modalities is pursued in the future for the treatment of RA, larger, controlled studies will be needed to understand its utility.

BACKGROUND: Peresolimab is a humanized IgG1 monoclonal antibody designed to stimulate the endogenous programmed cell death protein 1 (PD-1) inhibitory pathway. Stimulation of this pathway would be a novel approach to the treatment of patients with autoimmune or autoinflammatory diseases. METHODS: In this phase 2a, double-blind, randomized, placebo-controlled trial, we assigned, in a 2:1:1 ratio, adult patients with moderate-to-severe rheumatoid arthritis who had had an inadequate response to, a loss of response to, or unacceptable side effects with conventional synthetic disease-modifying antirheumatic drugs (DMARDs) or to biologic or targeted synthetic DMARDs to receive 700 mg of peresolimab, 300 mg of peresolimab, or placebo intravenously once every 4 weeks. The primary outcome was the change from baseline to week 12 in the Disease Activity Score for 28 joints based on the C-reactive protein level (DAS28-CRP). The DAS28-CRP ranges from 0 to 9.4, with higher scores indicating more severe disease. The primary comparison was between the 700-mg group and the placebo group. Secondary outcomes included the percentages of patients with American College of Rheumatology 20 (ACR20), ACR50, and ACR70 responses - defined as improvements from baseline of 20%, 50%, and 70% or more, respectively, in the numbers of tender and swollen joints and in at least three of five important domains - at week 12. RESULTS: At week 12, the change from baseline in the DAS28-CRP was significantly greater in the 700-mg peresolimab group than in the placebo group (least-squares mean change [±SE], -2.09±0.18 vs. -0.99±0.26; difference in change, -1.09 [95% confidence interval, -1.73 to -0.46]; P<0.001). The results of the analyses of secondary outcomes favored the 700-mg dose over placebo with respect to the ACR20 response but not with respect to the ACR50 and ACR70 responses. Adverse events were similar in the peresolimab and placebo groups. CONCLUSIONS: Peresolimab showed efficacy in a phase 2a trial in patients with rheumatoid arthritis. These results provide evidence that stimulation of the PD-1 receptor has potential efficacy in the treatment of rheumatoid arthritis. (Funded by Eli Lilly; ClinicalTrials.gov number, NCT04634253.).

INTRODUCTION: Upadacitinib (UPA) is an oral, selective Janus kinase inhibitor that has demonstrated favorable efficacy with an acceptable safety profile across a global, phase 3 program in rheumatoid arthritis (RA). This phase 2 open-label extension investigated the efficacy and safety of UPA through 6 years of treatment. METHODS: Patients from two phase 2b trials (BALANCE-1 and -2) enrolled in BALANCE-EXTEND (NCT02049138) and received open-label UPA 6 mg twice daily (BID). Dose increases to 12 mg BID were required for patients with < 20% improvement in swollen or tender joint counts at weeks 6 or 12 and permitted for those not achieving Clinical Disease Activity Index (CDAI) low disease activity (LDA; CDAI 2.8 to ≤ 10). Dose reduction to UPA 6 mg BID was permitted only for safety or tolerability reasons. After January 2017, the 6/12 mg BID doses were replaced by 15/30 mg once-daily extended-release equivalents. Efficacy and safety were monitored up to 6 years of UPA treatment; outcomes included rates of achievement of LDA or remission. Data were analyzed for patients who received the lower UPA dose throughout; titrated up to the higher UPA dose from weeks 6 or 12; or titrated to the higher UPA dose and back down. RESULTS: Overall, 493 patients entered BALANCE-EXTEND ('Never titrated', n = 306; 'Titrated up', n = 149; 'Titrated up and down', n = 38), and 223 patients (45%) completed the 6-year study. Total cumulative exposure was 1863 patient-years. Rates of LDA and remission were maintained through 6 years. Overall, 87%/70%/73% of patients in the 'Never titrated'/'Titrated up'/'Titrated up and down' groups achieved CDAI LDA at week 312, while the respective rates of Disease Activity Score 28 with C-reactive protein meeting LDA and remission criteria were 85%/69%/70% and 72%/46%/63%. Improvements in patient-reported outcomes were similar among the three groups. No new safety signals were identified. CONCLUSIONS: In this open-label extension of two phase 2 studies, UPA demonstrated sustained efficacy and an acceptable safety profile through 6 years of treatment in patients who completed the study. These data support a favorable long-term benefit-risk profile of UPA in patients with RA. TRIAL REGISTRATION: Trial registration number: NCT02049138.
ABSTRACT
INTRODUCTION: SEL-212 is a developmental treatment for uncontrolled gout characterized by serum uric acid (sUA) levels ≥ 6 mg/dl despite treatment. It comprises a novel PEGylated uricase (SEL-037; also called pegadricase) co-administered with tolerogenic nanoparticles containing sirolimus (rapamycin) (SEL-110; also called ImmTOR®), which mitigates the formation of anti-drug antibodies (ADAs) against uricase and SEL-037 (PEGylated uricase), thereby enabling sustained sUA control (sUA < 6 mg/dl). The aim of this study was to identify appropriate dosing for SEL-037 and SEL-110 for use in phase 3 clinical trials. METHODS: This open-label phase 2 study was conducted in adults with symptomatic gout and sUA ≥ 6 mg/dl. Participants received five monthly infusions of SEL-037 (0.2 or 0.4 mg/kg) alone or in combination with three or five monthly infusions of SEL-110 (0.05-0.15 mg/kg). Safety, tolerability, sUA, ADAs, and tophi were monitored for 6 months. RESULTS: A total of 152 adults completed the study. SEL-037 alone resulted in rapid sUA reductions that were not sustained beyond 30 days in most participants due to ADA formation and loss of uricase activity. Levels of ADAs decreased with increasing doses of SEL-110 up to 0.1 mg/kg, with anti-uricase titers < 1080 correlating with sustained sUA control and reductions in tophi. Overall, 66% of evaluable participants achieved sUA control at week 20 following five monthly doses of SEL-037 0.2 mg/kg + SEL-110 0.1-0.15 mg/kg, whereas only 26% achieved sUA control at week 20 when SEL-110 was withdrawn after week 12. Compared to other dose combinations, SEL-037 0.2 mg/kg + SEL-110 0.15 mg/kg achieved the greatest sUA control at week 12 and was well-tolerated with no safety concerns. CONCLUSION: Results provide continued support for the use of multiple monthly administrations of SEL-037 0.2 mg/kg + SEL-110 0.1-0.15 mg/kg in clinical trials for SEL-212.

ABSTRACT
BACKGROUND: Biologic therapies are often prescribed for patients with rheumatoid arthritis (RA) who have inadequate responses to or are intolerant of methotrexate (MTX) and patients with poor prognostic indicators. This post hoc analysis evaluated effectiveness and safety of intravenous golimumab + MTX vs golimumab without MTX in RA patients. METHODS: AWARE, a real-world, prospective and pragmatic, Phase 4 study, compared effectiveness and safety of golimumab and infliximab in biologic-naïve and biologic-experienced patients. All treatment decisions were at the discretion of the treating rheumatologist. Effectiveness was evaluated by mean change in CDAI scores at Months 6 and 12. Safety was monitored through approximately 1 year. RESULTS: Among 685 golimumab-treated patients, 420 (61%) received concomitant MTX during the study and 265 (39%) did not receive MTX after enrollment; 63% and 72%, respectively, discontinued the study. Relative to golimumab without MTX, golimumab + MTX patients had shorter mean disease duration (8.7 vs 10.0 years) and a lower proportion received prior biologics (60% vs 72%); mean ± standard deviation (SD) baseline CDAI scores were similar (30.8 ± 15.1 and 32.6 ± 15.4). Mean ± SD changes from baseline in CDAI scores at Months 6 and 12, respectively, were similar with golimumab + MTX (- 10.2 ± 14.2 and - 10.8 ± 13.8) and golimumab without MTX (- 9.6 ± 12.9 and - 9.9 ± 13.1). The incidence of adverse events/100 patient-years (PY) (95% confidence interval [CI]) was 155.6 (145.6, 166.1) for golimumab + MTX and 191.2 (176.2, 207.1) for golimumab without MTX; infections were the most common type. The incidence of infusion reactions/100PY (95% CI) was 2.1 (1.1, 3.6) for golimumab + MTX versus 5.1 (2.9, 8.3) for golimumab without MTX; none were considered serious. For golimumab + MTX versus golimumab without MTX, rates/100PY (95% CI) of serious infections, opportunistic infections, and malignancies were 2.6 (1.5, 4.3) versus 7.0 (4.4, 10.6), 0.9 (0.3, 2.0) versus 2.6 (1.1, 5.0), and 3.0 (1.7, 4.7) versus 1.0 (0.2, 2.8), respectively. CONCLUSIONS: Mean change in CDAI score in the golimumab without MTX group was generally similar to that of the golimumab + MTX group through 1 year, regardless of prior biologic therapy. Adverse events were consistent with the known IV golimumab safety profile. These results provide real world evidential data that may assist healthcare providers and patients with RA in making informed treatment decisions.

ABSTRACT
OBJECTIVE: To evaluate the long-term safety and efficacy of sarilumab with/without conventional synthetic (cs)DMARDs in RA. METHODS: The analyses evaluated two open-label extensions (OLEs): EXTEND and MONARCH OLE, which included patients from six randomized trials. Patients received sarilumab 200 mg once every 2 weeks (q2w) for at least 264 weeks up to 516 weeks (EXTEND: Sarilumab Monotherapy and Sarilumab + csDMARD groups) or for 276 weeks (MONARCH OLE: Continuation and Switch groups). Primary endpoints included safety, immunogenicity and changes in laboratory parameters. Secondary endpoints included clinical signs and symptoms along with health-related quality-of-life (HRQOL) questionnaires. RESULTS: The Sarilumab Monotherapy (n = 111), Continuation (n = 165) and Switch (n = 155) groups received sarilumab monotherapy, while the Sarilumab + csDMARD group (n = 1910) received sarilumab in combination with csDMARDs. Incidence of one or more treatment-emergent adverse events was 126 (Sarilumab Monotherapy group), 169 (Sarilumab + csDMARD group), 159 (Continuation group) and 159 (Switch group) events/100 patient-years. Neutropenia was the most common adverse event. Neutropenia was not associated with an increased incidence of infections. Most neutropenia cases normalized on-treatment. Adverse events of special interests, such as malignancies, major adverse cardiovascular events, venous thromboembolism and gastrointestinal perforations, were rare. Immunogenicity was low and not associated with hypersensitivity reactions or discontinuations due to lack or loss of efficacy. Improvements in clinical signs and symptoms and HRQOL, observed during the initial blinded trials, were maintained throughout the OLE assessment period. CONCLUSIONS: Long-term sarilumab treatment with/without csDMARDs in patients with RA revealed no new safety findings. Efficacy and HRQOL were maintained or further increased over the open-label assessment period.

OBJECTIVE: The study objective was to evaluate the safety, tolerability, pharmacodynamics, and preliminary efficacy of ATI-450 with methotrexate in patients with rheumatoid arthritis (RA). METHODS: A parallel-assignment, placebo-controlled, investigator-blinded/patient-blinded multicenter study evaluated patients with moderate-to-severe RA aged 18 to 70 years. Eligible patients were randomized (1:1) to ATI-450 50-mg oral tablets twice daily or placebo with a stable weekly dose of methotrexate for 12 weeks. The primary objective was to assess ATI-450 safety and tolerability. The secondary objectives were to assess the median percentage change from baseline high-sensitivity C-reactive protein (hs-CRP) levels, the mean change from baseline in Disease Activity Score in 28 joints based on CRP level (DAS28-CRP) and Rheumatoid Arthritis Magnetic Resonance Imaging Score hand-wrist assessments of synovitis or bone erosion at week 12, and the proportion of patients with American College of Rheumatology 20/50/70 (ACR 20/50/70) and with DAS28-CRP scores of less than 2.6. The exploratory outcomes were change from baseline in endogenous and ex vivo-stimulated cytokine levels. RESULTS: ATI-450 was well tolerated with no severe adverse events reported. ATI-450 reduced median hs-CRP levels by 42% or more at all posttreatment timepoints. In the ATI-450 group, a mean (median) decrease in DAS28-CRP score of 2.0 (2.1) was observed at week 12; proportions of patients with an ACR 20/50/70 response in the per-protocol population were 60%, 33%, and 20%, respectively, at week 12. Endogenous plasma levels of key inflammatory cytokines (tumor necrosis factor α, macrophage inflammatory protein 1ß, interleukin 6, interleukin 8) were reduced across the 12 treatment weeks. CONCLUSION: This is the first clinical study demonstrating that selective mitogen-activated protein kinase (MAPK)-activated protein kinase 2 (MK2) pathway blockade leads to a sustained antiinflammatory effect. This suggests that targeting the MK2 pathway mitigates the tachyphylaxis observed with p38 MAPK inhibitors in RA and supports further exploration.
ABSTRACT
OBJECTIVES: To present safety and efficacy of the JAK1 preferential inhibitor filgotinib in Japanese patients with prior inadequate response (IR) to methotrexate (MTX) from a 52-week randomised controlled parent study (PS) and long-term extension (LTE) through June 2020. METHODS: The PS (NCT02889796) randomised MTX-IR patients to filgotinib 200 (FIL200) or 100 mg (FIL100), adalimumab (ADA) 40 mg, or placebo; all took stable background MTX. At week (W) 24, placebo patients were rerandomised to FIL200 or FIL100. The primary endpoint was W12 American College of Rheumatology 20% improvement; safety was assessed by adverse event (AE) reporting. For the LTE (NCT03025308), eligible filgotinib patients continued FIL200/FIL100; ADA patients were rerandomised (blinded) to FIL200 or FIL100; all continued MTX. RESULTS: In all, 114/147 Japanese patients completed the PS, 115 enrolled in LTE, and 103 remained on study in June 2020. In the PS, AEs were consistent with the overall population, and W24 efficacy was maintained or improved through W52, comparable with the overall population. LTE AE incidences were similar between doses; filgotinib efficacy was consistent from baseline to W48 and similar between PS ADA and filgotinib patients. CONCLUSIONS: Among MTX-IR Japanese patients, filgotinib maintained efficacy over 1 year; LTE safety was consistent with the PS.

OBJECTIVE: Characterize safety of the Janus kinase-1 preferential inhibitor filgotinib (FIL) in Japanese patients with moderately to severely active rheumatoid arthritis (RA). METHODS: Data from three Phase 3 trials (NCT02889796, NCT02873936, and NCT02886728) and a long-term extension (NCT03025308) through September 2019 were integrated; patients received ≥1 dose of FIL 200 (FIL200) or 100 mg (FIL100) daily, or placebo (PBO). We calculated exposure-adjusted incidence rates (EAIRs) per 100 patient-years FIL exposure (100PYE) for treatment-emergent adverse events (TEAEs) and adverse events of special interest. RESULTS: Among 3691 total patients and 6080.7 PYE, 229 Japanese patients received FIL for 311.4 PYE (median 1.5, maximum 2.5 years). During the 12-week PBO-controlled period, serious TEAEs and TEAEs leading to study drug disruption were comparable between FIL and PBO. Serious infection rates were 1.9%, 0%, and 2% for FIL200, FIL100, and PBO during the PBO-controlled period; long-term FIL200 and FIL100 EAIRs were 3.8 and 2.1/100PYE. No herpes zoster (HZ) or major adverse cardiovascular events (MACEs) occurred during the PBO-controlled period; long-term FIL200 and FIL100 EAIRs were 3.0 and 2.1/100PYE (HZ) and 0.6 and 0/100PYE (MACE). CONCLUSION: Long-term FIL treatment (median 1.5, maximum 2.5âyears exposure) was well tolerated at 100- and 200-mg doses in Japanese patients with RA.

INTRODUCTION: This exploratory analysis of FINCH 1 (NCT02889796) examined filgotinib (FIL) efficacy and safety in a subgroup of patients with rheumatoid arthritis (RA) and inadequate response to methotrexate (MTX; MTX-IR) who had four poor prognostic factors (PPFs). METHODS: Patients with MTX-IR received placebo up to week (W)24 or FIL200 mg, FIL100 mg, or adalimumab up to W52; all received MTX. Efficacy and safety data were stratified by four PPFs versus fewer than four PPFs: seropositivity, high-sensitivity C-reactive protein (CRP) ≥ 6 mg/L, Disease Activity Score in 28 joints with CRP > 5.1, and erosions on X-rays. RESULTS: At baseline, 687/1755 patients had four PPFs. At W12, whether with four PPFs or fewer than four PPFs, response rates on all American College of Rheumatology (ACR) measures were significantly greater with FIL200 and FIL100 versus placebo. At W52, FIL200 ACR20/50/70 response rates remained at least numerically higher versus adalimumab in both subgroups. At W52, FIL200 reduced modified total Sharp score (mTSS) change versus adalimumab in patients with four or fewer than four PPFs. CONCLUSIONS: In high-risk (four PPFs) patients with MTX-IR RA, FIL200 and FIL100 showed similar reductions in disease activity versus placebo at W12 as in patients with fewer than four PPFs. mTSS in patients receiving FIL200 changed little from W24 to W52, while that in patients receiving FIL100 progressed comparably to patients who received adalimumab. Tolerability was comparable across treatment arms and subgroups.
