RESUMO

In an exploratory trial treating "long COVID" with the CCR5-binding antibody leronlimab, we observed significantly increased blood cell surface CCR5 in treated symptomatic responders but not in nonresponders or placebo-treated participants. These findings suggest an unexpected mechanism of abnormal immune downmodulation in some persons that is normalized by leronlimab. Clinical Trials Registration. NCT04678830.

RESUMO

BACKGROUND: As recommended in the current prescribing information, rituximab infusions in patients with rheumatoid arthritis (RA) take 4.25 hours for the first infusion and 3.25 hours for subsequent infusions, which is a burden on patients and the health care system. We therefore evaluated the safety of infusing rituximab at a faster rate for an infusion period of 2 hours in patients with RA. METHODS: Patients with an inadequate response to anti-TNF who were rituximab-naive or -experienced received 2 courses of rituximab: Infusion 1 (Day 1) was administered over the standard 4.25 hours, and Infusions 2 (Day 15), 3 (Day 168) and 4 (Day 182) were administered over a faster 2-hour period. The primary endpoint was incidence of infusion-related reactions (IRRs) associated with Infusion 2. RESULTS: Of the 351 patients enrolled, 87% and 13% were rituximab-naive and -experienced, respectively. The incidence (95% CI) of IRRs associated with Infusion 1 was 16.2% (12.5%, 20.5%) and consistent with weighted historical incidence of 20.7% (19.4%, 22.1%). The incidence (95% CI) of IRRs associated with Infusions 2, 3, and 4 compared with respective weighted historical incidences at the standard infusion rate was 6.5% (4.1%, 9.7%) vs 8.1% (7.2%, 9.1%); 5.9% (3.5%, 9.3%) vs 11.5% (10.3%, 12.8%); and 0.7 (0.1%, 2.6%) vs 5.0% (4.2%, 6.0%), respectively. All IRRs were grade 1 or 2, except for 3 grade 3 IRRs associated with Infusion 1 and 2 grade 3 IRRs associated with Infusion 2. Four patients experienced a total of 5 grade 3 IRRs; 3 of these patients continued on to received subsequent infusions at the faster rate. There were no serious IRRs. CONCLUSION: This study demonstrated that rituximab can be administered at the faster infusion rate at the second and subsequent infusions without increasing the rate or severity of IRRs.

RESUMO

INTRODUCTION: Hyrimoz®, (GP2017 [SDZ-ADL]), is a biosimilar to Humira® (REF-ADL). SDZ-ADL was approved in 2018 by both the United States Food and Drug Administration (US FDA) and European Medicines Agency (EMA) for the indications of REF-ADL not protected by orphan exclusivity. In 2023, the US FDA and EMA also approved a citrate-free high-concentration formulation (HCF) of SDZ-ADL. TOTALITY OF EVIDENCE-THE APPROACH: Approval of SDZ-ADL was based on data gathered using the US FDA, EMA and World Health Organization (WHO)-recommended step-wise Totality of Evidence approach. This approach is a robust dataset confirming high confidence in analytical, functional, pharmacokinetic (PK) and clinical biosimilarity between the biosimilar and reference medicine determined through analytical and clinical investigation. EVIDENCE OF BIOSIMILARITY: Evidence supporting the biosimilarity of SDZ-ADL and REF-ADL was reported at each stage of investigation. Comprehensive comparative analytical and functional assessments demonstrated that SDZ-ADL was analytically indistinguishable from REF-ADL in required critical quality attributes, including receptor binding. Phase I clinical data showed PK similarity of SDZ-ADL and REF-ADL in healthy volunteers, with similar safety, tolerability and immunogenicity profiles. Phase III confirmatory efficacy and safety studies, ADACCESS (included in US/EU dossiers) and ADMYRA (separate to US/EU dossiers), both confirmed that SDZ-ADL's efficacy, safety, and immunogenicity matched REF-ADL in all patient groups with no clinically meaningful differences. More recently, this data package was the basis for a citrate-free HCF of SDZ-ADL to be developed, and its PK, safety and immunogenicity were confirmed against the initially approved formulation of SDZ-ADL. CONCLUSION: Overall, the Totality of Evidence provided for biosimilar adalimumab, SDZ-ADL, confirmed the analytical, functional and clinical similarity of SDZ-ADL to REF-ADL, supporting its regulatory approval and providing a data bridge with which to evaluate and support the approval of citrate-free HCF SDZ-ADL for clinical use.


A biosimilar is a type of medicine that is designed to match the structure and function of a 'reference' biologic medicine. Hyrimoz® (SDZ-ADL) is a biosimilar of the adalimumab reference medicine, Humira® ([REF-ADL]). SDZ-ADL was approved in the US and Europe in 2018. For SDZ-ADL to be approved, a collection of evidence needed to be created, called the 'Totality of Evidence.' The purpose of this collection of data is to show there is a high confidence that the new biosimilar medicine matches the reference medicine, from the structure of the medicine to the effect of the medicine on the human body. For SDZ-ADL, this investigation started with comparing the physical structure and other functional properties of SDZ-ADL versus REF-ADL and ended with clinical studies in both healthy volunteers and in patients with diseases treated with adalimumab. This Totality of Evidence gathered for biosimilar adalimumab, SDZ-ADL, confirmed the similarity of SDZ-ADL to REF-ADL and therefore supported the approval of SDZ-ADL. In 2018, a citrate-free high-concentration version (high concentration formulation [HCF]) of REF-ADL was launched that matched REF-ADL. HCF REF-ADL has since become the primary formulation of REF-ADL used in practice. In 2023, a HCF version of SDZ-ADL was also approved in the US and EU based on evidence confirming that HCF SDZ-ADL matched SDZ-ADL. As SDZ-ADL had been previously confirmed to match the reference medicine, this meant that HCF SDZ-ADL could be directly compared against SDZ-ADL to confirm biosimilarity and support its approval.

RESUMO

WHAT IS THIS SUMMARY ABOUT?: This plain language summary explains, in simple terms, the results of a study from 2022 discussing a biosimilar medicine called GP2017 (called SDZ-ADL in this summary, sold as Hyrimoz®). This medicine is used to treat people with inflammatory conditions. This study investigated a new, high-concentration formulation of GP2017 (SDZ-ADL-HCF) in order to show that the high concentration option acts the same way in the body as SDZ-ADL. SDZ-ADL-HCF has been submitted for regulatory approval to health authorities on the basis of this study and was recently approved by the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA) for people with the inflammatory conditions that SDZ-ADL is used to treat. This newly developed formulation provides the option for receiving injections less often with reduced volumes which can have a positive impact on the injection experience and increase patient convenience. WHAT WAS THE AIM OF THE CURRENT STUDY?: This study looked at the pharmacokinetics of SDZ-ADL and SDZ-ADL-HCF, meaning it compared how the active medicine behaved in the body at different times after the injection of each of the formulations. The study also looked at how each formulation was recognized by the body's immune system (known as immunogenicity), and the side effects associated with each formulation. This study was randomly assigned and double-blinded, meaning that neither the participants nor the researchers knew which formulation each participant received. This reduces the risk of bias in the results. WHAT WERE THE FINDINGS FROM THE CURRENT STUDY?: The study found that an injection of SDZ-ADL-HCF resulted in similar amounts of the medicine being present within the blood as an injection of SDZ-ADL. This information was needed for the approval of SDZ-ADL-HCF. Participants also experienced similar immune reactions and the number of participants with side effects was similar between both concentrations of medicine. The results confirmed that SDZ-ADL-HCF behaves in the same way in the body and is expected to have the same treatment effects as SDZ-ADL, while at the same time offering an improved formulation with a more positive injection experience and increased patient convenience.

RESUMO

OBJECTIVE: The aim of this study was to assess long-term golimumab therapy in patients with rheumatoid arthritis (RA) who discontinued previous tumour necrosis factor alpha (TNFα) inhibitor(s) for any reason. METHODS: Results through week 24 of this multicentre, randomised, double-blind, placebo-controlled study of active RA (≥4 tender, ≥4 swollen joints) were previously reported. Patients received placebo (Group 1), 50 mg golimumab (Group 2) or 100 mg golimumab (Group 3) subcutaneous injections every 4 weeks. Patients from Groups 1 and 2 with <20% improvement in tender/swollen joints at week 16 early escaped to golimumab 50 mg and 100 mg, respectively. At week 24, Group 1 patients crossed over to golimumab 50 mg, Group 2 continued golimumab 50/100 mg per escape status and Group 3 maintained dosing. Data through week 160 are reported. RESULTS: 459 of the 461 randomised patients were treated; 236/459 (51%) continued treatment through week 160. From week 24 to week 100, ACR20 (≥20% improvement in American College of Rheumatology criteria) response and ≥0.25 unit HAQ (Health Assessment Questionnaire) improvement were sustained in 70-73% and 75-81% of responding patients, respectively. Overall at week 160, 63%, 67% and 57% of patients achieved ACR20 response and 59%, 65% and 64% had HAQ improvement ≥0.25 unit in Groups 1, 2 and 3, respectively. Adjusted for follow-up duration, adverse event incidences (95% CI) per 100 patient-years among patients treated with golimumab 50 mg and 100 mg were 4.70 (2.63 to 7.75) and 8.07 (6.02 to 10.58) for serious infection, 0.95 (0.20 to 2.77) and 2.04 (1.09 to 3.49) for malignancy and 0.00 (0.00 to 0.94) and 0.62 (0.17 to 1.59) for death, respectively. CONCLUSION: In patients with active RA who discontinued previous TNF-antagonist treatment, golimumab 50 and 100 mg injections every 4 weeks yielded sustained improvements in signs/symptoms and physical function in ∼57-67% of patients who continued treatment. Golimumab safety was consistent with other anti-TNF agents, although definitive conclusions regarding long-term safety require further monitoring.

RESUMO

Long-COVID is a syndrome characterized by debilitating symptoms that persist over 3 months after infection with the SARS-CoV-2 virus. It affects 15 to 33% of COVID-19 recovered patients and has no dedicated treatment. First, we found that ß-caryophyllene and pregnenolone have a significant synergistic effect in the resolution of LPS-induced sepsis and inflammation in mice. Then we combined these two compounds with seven others and designed a unique dietary supplement formulation to alleviate long COVID inflammatory and neurological disorders. We performed a one-arm open-labeled study at a single site with 51 eligible patients from 18 states. Each participant recorded the severity level of 12 symptoms (including fatigue, weakness, cardiac and neurological symptoms, shortness of breath, gastrointestinal disorders, ageusia or anosmia, anxiety, joint pain, rash, cough, and insomnia) at baseline, 2- and 4-week time points. On average, all the symptoms were significantly milder after 2 weeks, with further improvement after 4 weeks. Importantly, each symptom was significantly attenuated in 72 to 84% of the participants. There were no significant adverse effects. Our data indicate that the use of this nutraceutical product is a safe and significantly efficient option to reduce multiple symptoms of long COVID.

RESUMO

OBJECTIVE: To assess the efficacy and safety profiles of two different rituximab retreatment regimens in patients with RA. METHODS: Four hundred and ninety-three RA patients with an inadequate response to MTX recruited into rituximab Phase II/III studies received further courses of open-label rituximab based on two approaches: (i) treatment to target (TT): patients assessed 24 weeks after each course and retreated if not in remission [DAS in 28 joints based on ESR (DAS-28-ESR) ≥ 2.6]; (ii) treatment as needed (PRN): patients retreated at the physician's discretion ≥24 weeks following the first course and ≥16 weeks following further courses, if both swollen and tender joint counts were ≥8. All courses consisted of i.v. rituximab 2 × 1000 mg 2 weeks apart plus MTX. Observed data were analysed according to treatment strategy. RESULTS: Multiple courses of rituximab maintained or improved responses irrespective of regimen. TT provided tighter control of disease activity with significantly greater improvements in DAS-28-ESR and lower HAQ-disability index scores vs PRN. TT resulted in significantly more patients achieving major clinical response. PRN resulted in recurrence of disease symptoms between courses, with TT significantly reducing the incidence of RA flares. Despite more frequent retreatment with TT compared with PRN, the rates of serious adverse events and serious infections were comparable between regimens. CONCLUSIONS: Retreatment with rituximab based on 24-week evaluations and to a target of DAS-28-ESR remission leads to improved efficacy and tighter control of disease activity compared with PRN without a compromised safety profile. TT may be the preferable rituximab treatment regimen for patients with RA.

RESUMO

BACKGROUND: SDZ-ADL (GP2017; Sandoz GmbH, Austria) is an EMA-/FDA-approved adalimumab biosimilar. The effect of SDZ-ADL on quality of life (QoL) and patient-reported outcomes (PROs) was assessed as part of two phase III studies, one in patients with moderate-to-severe chronic plaque psoriasis (PsO; ADACCESS) and the other in patients with rheumatoid arthritis (RA; ADMYRA). Additionally, ADACCESS included patients with psoriatic arthritis (PsA). METHODS: ADACCESS included 465 patients with PsO, whereas ADMYRA included 353 patients with RA. Both studies evaluated and confirmed equivalent efficacy, similar safety, and immunogenicity of SDZ-ADL with reference adalimumab (ref-ADL). A third of patients underwent multiple (four) treatment switches between study treatments starting at Week 17 (ADACCESS); all patients switched from ref-ADL to SDZ-ADL at Week 24 (ADMYRA). Assessed PROs included Dermatology Life Quality Index (DLQI) and EuroQol five-dimension health status questionnaire (EQ-5D-5L) in ADACCESS, Functional Assessment of Chronic Illness Therapy-Fatigue Scale (FACIT-Fatigue) score in ADMYRA, and Health Assessment Questionnaire-Disability Index (HAQ-DI) in both studies. RESULTS: In both studies, baseline scores for all PRO assessments were comparable between the two treatment groups. In ADACCESS, mean DLQI decreased from baseline in both groups, and the mean (standard deviation [SD]) percent reductions from baseline in DLQI were comparable between groups at Week 17 (SDZ-ADL, - 64.5 [80.3]; ref-ADL, - 70.6 [41.7]), which were sustained after the switch at Week 51 ('continued SDZ-ADL,' - 79.7 [36.2]; 'continued ref-ADL,' - 80.8 [44.6]; 'switched to SDZ-ADL,' - 70.7 [32.2]; 'switched to ref-ADL,' - 69.3 [49.6]). In ADACCESS, the proportion of patients with an EQ-5D-5L score of 1 (no problems) increased from baseline for all five dimensions in all treatment groups and was comparable between treatment groups at Week 51. In ADACCESS, in patients with PsA at baseline, mean (SD) HAQ-DI scores decreased from baseline in both treatment groups, and scores were comparable between groups at Week 17 (SDZ-ADL, 0.5 [0.6]; ref-ADL, 0.5 [0.6]) and after switching at Week 51 ('continued SDZ-ADL,' 0.4 [0.5]; 'continued ref-ADL,' 0.4 [0.6]; 'switched to SDZ-ADL,' 0.5 [0.8]; 'switched to ref-ADL,' 0.7 [0.6]). In ADMYRA, proportion of patients achieving HAQ-DI in the normal range (≤ 0.5) was comparable between treatment groups at Week 24 (SDZ-ADL, 37.8%; ref-ADL, 36.3%) and after switching at Week 48 ('SDZ-ADL,' 41.6%; 'ref-ADL/switched to SDZ-ADL,' 40.0%). In ADMYRA, mean FACIT-Fatigue scores increased from baseline in both treatment groups. At Week 24, mean (SD) percent change from baseline in the FACIT-Fatigue scores was 75.4 (135.5) in SDZ-ADL and 73.0 (96.3) in ref-ADL groups; the scores were sustained after switching at Week 48. CONCLUSION: Treatment with SDZ-ADL and ref-ADL resulted in comparable improvements in PROs as well as QoL scores across the three diseases, PsO, PsA, and RA. Switching between SDZ-ADL and ref-ADL had no negative impact on PROs across the reported period. CLINICAL TRIALS. GOV IDENTIFIER: NCT02744755, NCT02016105.

RESUMO

BACKGROUND: Tumour necrosis factor alpha (TNFalpha) inhibitors are frequently used to treat rheumatoid arthritis, but whether use of a different TNFalpha inhibitor can improve patient response is unknown. We assess the efficacy and safety of the TNFalpha inhibitor golimumab in patients with active rheumatoid arthritis who had previously received one or more TNFalpha inhibitors. METHODS: 461 patients with active rheumatoid arthritis from 82 sites in 10 countries were randomly allocated by interactive voice response system, stratified by study site and methotrexate use, to receive subcutaneous injections of placebo (n=155), 50 mg golimumab (n=153), or 100 mg golimumab (n=153) every 4 weeks between Feb 21, 2006, and Sept 26, 2007. Allocation was double-blind. Eligible patients had been treated with at least one dose of a TNFalpha inhibitor previously. Patients continued stable doses of methotrexate, sulfasalazine, hydroxychloroquine, oral corticosteroids, and non-steroidal anti-inflammatory drugs. The primary endpoint was achievement at week 14 of 20% or higher improvement in American College of Rheumatology criteria for assessment of rheumatoid arthritis (ACR20). At week 16, patients who had less than 20% improvement in tender and swollen joint counts were given rescue therapy and changed treatment from placebo to 50 mg golimumab, or from 50 mg to 100 mg golimumab. Drug efficacy was assessed by intention to treat and safety was assessed according to the study drug given. This study is registered with ClinicalTrials.gov, number NCT00299546. FINDINGS: Patients had discontinued previous TNFalpha inhibitors because of lack of effectiveness (269 [58%] patients) or reasons unrelated to effectiveness (246 [53%] patients), such as intolerance and accessibility issues. Patients had active disease, which was indicated by a median of 14.0 (IQR 9.0-22.0) swollen and 26.0 (16.0-41.0) tender joints for the whole group. 28 (18%) patients on placebo, 54 (35%) patients on 50 mg golimumab (odds ratio 2.5 [95% CI 1.5-4.2], p=0.0006), and 58 (38%) patients on 100 mg golimumab (2.8 [1.6-4.7], p=0.0001) achieved ACR20 at week 14. Two patients were never treated, and 57 patients did not complete the study because of adverse events, unsatisfactory treatment effect, loss to follow-up, death, or other reasons. 155 patients on placebo, 153 on 50 mg golimumab, and 153 on 100 mg golimumab were assessed for drug efficacy. For weeks 1-16, serious adverse events were recorded in 11 (7%) patients on placebo, 8 (5%) on 50 mg golimumab, and 4 (3%) on 100 mg golimumab. For weeks 1-24, after some patients were given rescue therapy, serious adverse events were recorded in 15 (10%) patients on placebo, 14 (5%) on 50 mg golimumab, and 8 (4%) on 100 mg golimumab. INTERPRETATION: Golimumab reduced the signs and symptoms of rheumatoid arthritis in patients with active disease who had previously received one or more TNFalpha inhibitors.

RESUMO

BACKGROUND: Sandoz adalimumab SDZ-ADL (GP-2017) is an approved adalimumab biosimilar with similar efficacy and comparable safety and immunogenicity to reference adalimumab (ref-ADL) as confirmed by analytical, pharmacokinetic and confirmatory studies. ADMYRA, a phase III double-blind study, was conducted with an aim to generate efficacy, safety and immunogenicity comparability data in patients with moderate-to-severe rheumatoid arthritis (RA) having inadequate response to disease-modifying anti-rheumatic drugs (DMARDs) including methotrexate (MTX). The study also evaluated an aspect of 'switching' reference product to the biosimilar in terms of efficacy, safety and immunogenicity up to Week 48. METHODS: Eligible patients (N = 353) were randomized 1:1 to receive subcutaneous (sc) SDZ-ADL 40 mg (n = 177) or ref-ADL (n = 176) every other week from Week 0 to Week 24. At Week 24, all patients with at least a moderate response by Disease Activity Score-28 including high-sensitivity C-reactive protein (DAS28-CRP) in the SDZ-ADL group continued SDZ-ADL (n = 159), and in the ref-ADL group were switched to SDZ-ADL (n = 166), treated for up to 46 weeks. The primary endpoint was change in DAS28-CRP from baseline at Week 12. Other efficacy endpoints included proportion of patients with European League Against Rheumatism (EULAR) response, EULAR remission, Boolean remission, safety and immunogenicity. RESULTS: The DAS28-CRP score changes from baseline at Week 12 were similar between SDZ-ADL (- 2.16) and ref-ADL (- 2.18) with a mean difference (95% CI) of 0.02 (- 0.24 to 0.27), which was within the pre-specified equivalence margin of ± 0.6. After switching treatment from ref-ADL to SDZ-ADL, the mean DAS28-CRP change was similar between the SDZ-ADL and 'ref-ADL/switched SDZ-ADL' group (- 3.09 vs - 3.05). The proportion of patients with good/moderate EULAR response was 69.2%/29.0% in the SDZ-ADL group and 68.0%/29.6% in the 'ref-ADL/switched SDZ-ADL' group. The proportion of patients in EULAR remission was 51.4% and 54.4% and in Boolean remission was 16.8% and 21.6% for SDZ-ADL and 'ref-ADL/switched SDZ-ADL' groups, respectively. The secondary endpoints were similar across the treatment groups. The incidence of adverse events (AEs) and injection-site reactions were low and similar between SDZ-ADL and 'ref-ADL/switched SDZ-ADL' groups (AEs 70.6% vs 68.8%, injection-site reactions 4.0% vs 6.3%), and most of these patients experienced AEs of mild or moderate severity. Antidrug antibodies were detected in 24.2% and 25.6% of patients treated with SDZ-ADL and 'ref-ADL/switched SDZ-ADL', respectively, from baseline to Week 48, of which 72.5% in SDZ-ADL and 79.1% in 'ref-ADL/switched SDZ-ADL' groups were neutralizing. CONCLUSIONS: In patients with moderate-to-severe RA who had an inadequate response to DMARDs, SDZ-ADL demonstrated a similar efficacy and a comparable safety and immunogenicity profile to ref-ADL. Efficacy was sustained after switching from ref-ADL to SDZ-ADL with no impact on safety (NCT02744755).

RESUMO

Background The inflammatory reflex plays a role in regulating innate and adaptive immunity by modulating cellular and molecular inflammatory pathways. The vagus nerve is a major constituent of the inflammatory reflex and studies have shown that the reflex can be activated by electrical stimulation of the vagus nerve. In this first in-human pilot study, we assessed the safety and efficacy of a novel miniaturised vagus nerve stimulation (VNS) device for the treatment of multidrug-refractory rheumatoid arthritis. METHODS: Participants with moderately to severely active rheumatoid arthritis and prior insufficient response to two or more biological disease-modifying anti-rheumatic drugs or Janus kinase inhibitors with at least two different modes of action were enrolled in a two-stage study done at five clinical research sites in the USA. Stage 1 was open label; participants were implanted with a miniaturised VNS device, which was activated for 1 min once a day. In stage 2, participants were randomly assigned (1:1:1) to receive active stimulation (1 min once a day or 1 min four times a day) or sham stimulation (device implanted but not activated), with the sites and participants masked to treatment assignment. The primary outcome was incidence of treatment-emergent adverse events. Clinical efficacy was assessed as a key secondary outcome. The study was registered with ClinicalTrials.gov, NCT03437473. FINDINGS: 14 patients were enrolled between March 13 and Aug 8, 2018. Three patients received stimulation in stage 1 and, following safety review board approval, the remaining 11 patients were implanted during stage 2 and randomly assigned to receive 1 min of stimulation once daily (n=3), 1 min of stimulation four times daily (n=4), or no stimulation (n=4) for 12 weeks. There were no device-related or treatment-related serious adverse events. Surgery-related adverse events were Horner's syndrome and vocal cord paralysis (in one patient each), which resolved without clinically significant sequelae. No deaths were recorded. INTERPRETATION: VNS with a miniaturised neurostimulator was safe and well tolerated and reduced signs and symptoms of rheumatoid arthritis in patients with multidrug-refractory disease. These results support further evaluation in a larger randomised sham-controlled study. FUNDING: SetPoint Medical.

RESUMO

Low-field extremity magnetic resonance imaging (MRI) has been developed as an alternative method for detecting inflammatory changes and structural damage associated with rheumatoid arthritis (RA). Studies have shown that extremity MRI is able to predict future joint damage in patients with early RA and is more sensitive than conventional radiography at detecting joint erosions. This report uses four different cases to illustrate how extremity MRI can be used to monitor disease activity and inform treatment decisions during the management of RA in the routine clinical practice setting.

RESUMO

OBJECTIVE: Two surveys were conducted with patients with rheumatologic diseases to evaluate perceptions of different routes of administration (intravenous [IV] or subcutaneous [SC]) for biologic therapy. METHODS: In Survey I, patient preferences toward biologic treatment were evaluated at a rheumatology practice in Buffalo, New York. In Survey II, Canadian patients enrolled in the BioAdvance patient support program and scheduled to receive IV biologic therapy were asked about their opinions of IV treatment. RESULTS: In Survey I, 243 rheumatology patients participated. Median patient age was 60 years, 76% were female, and 44% were naive to treatment with biologic agents. Among biologic-naive patients, the majority (56%) were open to either SC or IV treatment; biologic-naive women were more likely than men to express a preference for the route of administration. In Survey II, 1,598 patients from the BioAdvance program (including 306 rheumatology patients) completed the full survey. Among the rheumatology patients, the median age was 49 years, 58% were female, and 61% had not previously taken biologics before enrolling in the BioAdvance program. The median rating of IV favorability (on a 10-point scale, with higher numbers indicating increased favorability) recalled by rheumatology patients was 5 prior to their first program infusion, which increased to 9 after multiple treatment infusions. CONCLUSION: These survey results indicate that patients with rheumatoid arthritis are generally open to IV treatment and express high satisfaction with IV therapy. Additional patient and provider education may improve shared decision-making regarding biologic therapy administration options.

RESUMO

OBJECTIVE: To evaluate patient perspectives regarding utilization of intravenous (IV) therapy for inflammatory arthritis (IA). METHODS: This was a single-center, noninterventional, patient questionnaire-based study of adult IA patients currently receiving IV biologics. At a single visit, patients completed the questionnaire comprising 30 questions centered on their experience receiving an intravenously administered therapy to treat their IA. The questionnaire included questions on patient demographics, disease characteristics, and previous biologic treatment for IA (subcutaneous [SC] and IV). Patients rated their level of agreement with statements regarding satisfaction with current IV biologic therapy and potential advantages and disadvantages of IV biologic therapy using a 5-point Likert scale (1= strongly disagree, 5= strongly agree). RESULTS: One hundred patients were enrolled and completed the survey; 66% were female and the mean age was 58 years. Before IV treatment, 97% of patients received information regarding therapy options. Ninety patients ranked their satisfaction with current IV therapy as 4 or 5. The proportion of patients with an "extremely favorable" perception of IV therapy increased from 33% to 71% following initiation of their current medication. Thirty-one patients had previously received SC therapies to treat their IA. CONCLUSION: These results demonstrated an overall favorable perception of IV therapy among this patient population. Patients previously treated with SC therapy also had a positive shift in the perception of IV therapy after initiating IV therapy. Patients' perception and preference for treatment options should be highly considered by the treating physician during or as part of a shared decision-making process.

RESUMO

INTRODUCTION: The aim of this study was to assess long-term golimumab therapy in rheumatoid arthritis (RA) patients who discontinued previous tumor necrosis factor-α (TNF)-inhibitor(s). METHODS: Patients enrolled into this multicenter, randomized, double-blind, placebo-controlled study of active RA (≥4 tender, ≥4 swollen joints) received placebo (Group 1) or golimumab 50 mg (Group 2) or 100 mg (Group 3) injections every 4 weeks. Patients in Groups 1 and 2 with inadequate response at week 16 escaped to golimumab 50 and 100 mg, respectively. At week 24, Group 1 patients crossed-over to golimumab 50 mg, Group 2 continued golimumab 50/100 mg per escape status, and Group 3 maintained dosing. During the long-term-extension (LTE), golimumab 50 mg could be increased to 100 mg, and 100 mg could be decreased to 50 mg. Data through 5 years are reported for all patients (safety) and patients using methotrexate (efficacy, intention-to-treat (ITT) analysis with last-observation-carried-forward for missing data and non-responder imputation for unsatisfactory efficacy discontinuations). RESULTS: In total, 459 of 461 randomized patients received the study agent, 304 of whom were methotrexate-treated and included in efficacy analyses. Through week 256, the proportions of methotrexate-treated patients achieving American-College-of-Rheumatology (ACR) responses were 37.6% to 47.0% for ACR20, 21.4% to 35.0% for ACR50, and 7.8% to 17.0% for ACR70 response across randomized groups. Golimumab safety through week 268 was generally consistent with that at week 24 and week 160 and other anti-TNF agents. CONCLUSIONS: In some patients with active RA discontinuing previous TNF-antagonist therapy, golimumab safety and efficacy, assessed conservatively with ITT analyses, was confirmed through 5 years.
