To compare the safety, efficacy, and immunogenicity of MSB11022 (acetate-buffered formulation), an adalimumab biosimilar, with the reference product.
AURIEL-RA study was a phase 3, multicenter, randomized, double-blind, parallel group trial (NCT03052322). Patients with moderately-to-severely active rheumatoid arthritis (RA) with an inadequate response to methotrexate were randomized 1:1 to MSB11022 or reference adalimumab. The primary endpoint was the incidence of treatment-emergent adverse events of special interest (AESIs) (predefined as hypersensitivity) up to week 52. The key secondary endpoint was ACR20 (≥ 20% improvement in American College of Rheumatology core set measurements from baseline) at week 12. Other efficacy endpoints, quality of life, immunogenicity, and pharmacokinetic parameters were evaluated up to week 52. Secondary safety endpoints were evaluated up to week 52 and at a 4-month safety follow-up.
In total, 288 patients were randomized. The proportion of patients experiencing ≥ 1 treatment-emergent AESI up to week 52 was similar between trial arms: 6 patients (4.2%; 95% CI 1.56, 8.91) receiving MSB11022, and 8 patients (5.5%; 95% CI 2.41, 10.58) receiving reference adalimumab. No clinically meaningful differences in efficacy, quality of life, or immunogenicity were seen between treatment arms up to week 52. No notable difference in the incidence of treatment-emergent adverse events was observed between treatment arms up to the end of the follow-up period.
These results suggest MSB11022 and reference adalimumab are similar in patients with moderately-to-severely active rheumatoid arthritis in terms of safety, immunogenicity, and efficacy. AURIEL-RA provides evidence to support the similarity of MSB11022 and adalimumab.
• Incidences of hypersensitivity events were similar for MSB11022 (modified buffer) and reference adalimumab.
• There was no difference in local reactions between MSB11022 (modified buffer) and reference adalimumab.
• AURIEL-RA confirms the equivalence in efficacy and immunogenicity of MSB11022 (modified buffer) and reference adalimumab.
Rheumatoid arthritis (RA) is an autoimmune disease characterized by chronic inflammation of peripheral joints. Irreversible cartilage and bone destruction can occur, leading to pain, disability, and functional decline [1, 2]. Biologics, such as the tumor necrosis factor (TNF) alpha inhibitor adalimumab, have been shown to have significant efficacy in RA, including improvements in disease activity and quality of life (QoL), and in slowing radiographic progression of structural damage to joints [3,4,5]. However, biologics are expensive, and globally, many patients do not have access to these treatments .
The introduction of biosimilars has been shown to reduce healthcare costs and may enable more patients to be treated within the same budget constraints [7, 8]. In the treatment of RA, this is now reflected in international guidelines, such as those provided by the European League Against Rheumatism (EULAR), which recommend the use of cost-effective treatment approaches as long as safety and outcomes are similar and in line with established therapeutic paradigms .
MSB11022 is a proposed adalimumab biosimilar that has been shown to be structurally and functionally similar to the reference adalimumab molecule based on an extensive analytical characterization exercise . MSB11022 has been developed using two formulations: one in a citrate-based buffer, and one in an acetate-based buffer. Both contain the same pharmacologically active molecule. In a phase 1, double-blind study in healthy volunteers, bioequivalence and comparable safety, tolerability, and immunogenicity profiles were demonstrated between MSB11022 and reference adalimumab (both in a citrate-based buffer) . Therapeutic equivalence between MSB11022 and reference adalimumab (both in a citrate-based buffer) in terms of efficacy, safety, and immunogenicity was shown in the pivotal AURIEL-PsO study. In patients with moderate-to-severe chronic plaque psoriasis, the Psoriasis Area and Severity Index (PASI) 75 response rate and the mean improvement in PASI were similar between the trial arms. QoL scores and safety and immunogenicity profiles were also similar . In an additional healthy volunteer study (EMR200588-003, unpublished data), MSB11022 (acetate formulation) demonstrated bioequivalence and a comparable safety and immunogenicity profile to MSB11022 (citrate formulation).
Here we report the results from the AURIEL-RA study designed to compare the safety, immunogenicity, and efficacy of MSB11022 (acetate formulation) with reference adalimumab (citrate formulation) in patients with moderately-to-severely active RA with an inadequate response to methotrexate.
The AURIEL-RA study (NCT03052322; EudraCT 2016-002852-26) was a phase 3 multicenter, randomized, double-blind parallel group trial conducted from 31 January 2017 to 7 August 2018. The study was conducted in 47 centers across 6 European countries. The trial consisted of 3 periods: a 4-week screening period, a 52-week double-blind treatment period, and a 4-month safety follow-up period. Following the screening period, patients were randomized 1:1 in permuted blocks by a central interactive web response system to receive MSB11022 (acetate formulation) or reference adalimumab (Humira® citrate formulation; AbbVie Inc., North Chicago, IL, USA; European Union authorized). Patients were stratified by previous systemic therapy use: non-biologic versus biologic. Patients who previously received both biologic and non-biologic systemic therapies were assigned to the “biologic” group. The participation of patients in the previous biologic systemic therapy stratum was capped at 20% of the total number of patients randomized. The trial was double-blinded and blinding was maintained throughout the trial. Emergency unblinding did not occur. MSB11022 or reference adalimumab was administered at a dose of 40 mg subcutaneously every other week starting at baseline, up to, and including week 48.
Patients who achieved less than 20% improvement in both swollen and tender joint counts at week 24 or at any scheduled visit from week 24 up to week 52 discontinued study treatment (but participated in the safety and immunogenicity assessments).
Patients aged ≥ 18 years with a clinical diagnosis of moderately-to-severely active RA with disease duration ≥ 6 months from confirmed diagnosis were eligible for inclusion (defined by the 2010 revised American College of Rheumatology (ACR)/EULAR criteria or the 1987 Criteria of the American Rheumatology Association) [13, 14]. Patients were required to have ≥ 6 swollen joints and ≥ 6 tender joints (from the 66/68 joint count system) at screening and randomization, and either erythrocyte sedimentation rate (ESR) ≥ 28 mm/h or serum C-reactive protein (CRP) ≥ 1.0 mg/dl at screening. Patients were treated with methotrexate for ≥ 12 weeks prior to baseline with both a stable route of administration (oral or parenteral) and stable dose (10–25 mg/week) for ≥ 4 weeks prior to screening. Patients were required to be adalimumab-naïve and to have discontinued infliximab, certolizumab pegol, or golimumab at least 8 weeks prior to screening. Etanercept had to be discontinued 4 weeks prior to screening. Exposure to previous biologics was limited to one TNFα inhibitor other than adalimumab. Patients had to have no history of tuberculosis, no active tuberculosis, and no history or evidence of latent tuberculosis. Detailed exclusion criteria and prohibited medications are listed in Online Resource 2.
All subjects provided written informed consent. The study was conducted in accordance with the current International Council for Harmonisation Good Clinical Practice and the Declaration of Helsinki as well as with applicable local regulations.
The primary endpoint was the incidence of treatment-emergent adverse events of special interest (AESIs) (predefined as hypersensitivity according to Standardized MedDRA Queries [narrow] as per the latest MedDRA version) up to and including week 52. The key secondary endpoint was ACR20 at week 12 (defined as improvement of ≥ 20% from baseline in the ACR core set of measurements) . Other secondary efficacy endpoints included ACR20 at weeks 2, 4, 8, and 52, and assessments of ACR50, ACR70, Disease Activity Score 28-joint count-ESR (DAS28-ESR), Clinical Disease Activity Index (CDAI), Simplified Disease Activity Index (SDAI), and ACR/EULAR Boolean remission rates at weeks 2, 4, 8, 12, 24, and 52. QoL was assessed using the Disability Index (HAQ-DI) , 36-item Short Form Health Survey (SF-36) [17, 18], and Euro Quality of Life – 5 dimensions and 5 levels (EQ-5D-5L)  questionnaires at baseline and weeks 2, 4, 8, 12, 24, and 52 (HAQ-DI only at weeks 2, 4, and 8).
Antidrug antibodies (ADAs) and neutralizing antibodies (NAbs) were assessed at baseline and at scheduled visits at weeks 2, 4, 12, 24, 36, and 52. Blood samples were taken pre-dose and serum concentrations were quantified using a validated enzyme-linked immunosorbent assay. The incidence of ADAs was assessed using a highly sensitive and drug-tolerant validated bioanalytical method based on the Meso Scale Discovery Electrochemiluminescent platform (Meso Scale Diagnostics, Rockville, MD, USA). The assay sensitivity was 86.4 ng/mL with a drug tolerance of 250 μg/mL at the low positive control level of 129.6 ng/mL. In addition, all patients had blood samples taken for population pharmacokinetic (PK) assessment pre-first dose, and then prior to dosing on weeks 2, 4, 12, 24, 36, and 52.
Secondary safety endpoints included the incidence of treatment-emergent adverse events (TEAEs) and serious adverse events (SAEs) up to week 52 and at the 4-month safety follow-up. Injection site pain was evaluated using a 0–100 visual analogue scale (VAS) after 3 consecutive administrations of study drug (weeks 4, 6, and 8). Pain was evaluated immediately post-injection, and at 15 min and 1 h post-injection.
The primary endpoint was evaluated using the safety analysis set, which consisted of all randomized patients who received at least one dose of study drug. The incidence of treatment-emergent AESIs and 95% CIs were calculated for each treatment group. 95% CIs for the difference in incidence between groups were also calculated for any observed clinical events of AESIs (hypersensitivity) observed in ≥ 3% of patients. Therefore, the study was descriptive, and a sample size of approximately 260 patients was chosen to ensure at least 100 patients remained in each treatment arm at week 52. According to scientific advice from the European Medicines Agency, this sample size is informative for a study primarily focusing on safety in a biosimilar setting . As such, this study was not powered to demonstrate equivalence between MSB11022 and reference adalimumab, and there was no hypothesis tested to justify the sample size.
For the key secondary endpoint, ACR20 at week 12, 95% CIs were calculated for each treatment group. This analysis was performed in both the per-protocol (PP; all randomized and treated patients without important protocol deviations) and intention-to-treat (ITT; all randomized patients) sets. Other secondary endpoints, including efficacy and QoL endpoints, were assessed using the PP and ITT sets, and were summarized descriptively according to the type of outcome. Immunogenicity and safety data, including injection site pain, were summarized descriptively using the safety analysis set. PK data were summarized using the PK analysis set. Analyses exploring associations between PK and immunogenicity and between PK and efficacy also used the PK analysis set.
Disposition and demographics
A total of 288 patients were randomized (ITT: MSB11022, n = 143; reference adalimumab, n = 145). (Fig. 1). All randomized patients received at least one dose of study drug and were included in the safety analysis set. Seven patients (4.9%) in the MSB11022 arm and 12 patients (8.3%) in the reference adalimumab arm were excluded from the PP analysis (PP: MSB11022, n = 136; reference adalimumab, n = 133). Reasons for exclusion from the PP set included being assigned to an incorrect randomization stratum with respect to systemic therapy previously received, using prohibited medication(s) and/or therapies at any time during the study, being < 80% compliant to subcutaneous injection administration, ACR20 could not be calculated at week 12, compliance was below 80% up to week 10, and discontinuing treatment before week 12. Patient demographics and baseline characteristics were similar between treatment arms (Table 1). In both treatment arms, the median number of injections was 25 and the median duration of exposure was 50 weeks.
Few treatment-emergent AESIs of hypersensitivity were reported during the study. The proportions of patients who experienced ≥ 1 hypersensitivity AESI by week 52 was similar across treatment arms: 6 patients (4.2%; 95% CI 1.56, 8.91) in the MSB11022 arm and 8 patients (5.5%; 95% CI 2.41, 10.58) in the reference adalimumab arm (Fig. 2). The types of hypersensitivity reactions recorded were comparable between treatment arms (Table 2). Two hypersensitivity reactions qualified as SAEs: one event of dermatitis (grade 3) in the reference adalimumab arm, and one anaphylactic reaction (grade 4) in the MSB11022 arm, which was considered to be treatment-related. Both events occurred after the completion of the study treatment. The first patient was hospitalized with a generalized erythematous exfoliating dermatitis of the whole body with scalp involvement and secondary superinfection. After 10 days of treatment, the subject was discharged from hospital with significant resorption of the lesions with no new eruptions and improvement of pruritus-related symptoms. The second patient experienced dyspnea, dizziness, vertigo, and nausea 30 min after administration of last study dose of MSB11022. The event resolved with treatment (chloropyramine and methylprednisolone). No subjects permanently discontinued treatment or withdrew from the study due to hypersensitivity, and there were no deaths reported subsequent to a hypersensitivity reaction.
Key secondary endpoint
Efficacy data are presented for the ITT population, and similar results were observed in the PP population. The proportion of patients who achieved ACR20 at week 12 was similar between MSB11022 and reference adalimumab (MSB11022: n = 113 [79.6%]; reference adalimumab: n = 114 [80.9%]; 95% CI for treatment difference −10.55, 8.04). This similarity was maintained up to week 52 (Fig. 3a).
Other efficacy endpoints
The ACR50 and ACR70 response rates (Fig. 3a), DAS28-ESR scores (Fig. 3b), and SDAI and CDAI scores (Online Resource 3) were also similar between the MSB11022 and reference adalimumab treatment arms at scheduled visits up to week 52 in the ITT population and PP populations.
Quality of life endpoints and pain scores
EQ-5D-5L index values, EQ-5D-5L VAS, SF-36 scores, and HAQ-DI scores were similar for MSB11022 versus reference adalimumab at weeks 24 and 52 (Online Resource 4).
Injection site pain scores were low in both treatment arms at week 4, and further decreased with subsequent injections in the ITT population (Online Resource 5). The majority of patients experienced a 0 or very low pain score: based on third quartile data, at least 75% of patients reported a score immediately post-injection of ≤ 6 (out of 100) at week 4, ≤ 3 at week 6, and ≤ 2 at week 8.
Immunogenicity and pharmacokinetics
During the 52-week treatment period, 80.4% and 71.7% of patients in the MSB11022 and reference adalimumab treatment arms had at least one positive ADA result, and 39.9% and 39.3% of patients in the MSB11022 and reference adalimumab arms, respectively, had a positive NAb result (Fig. 4). At week 12, the mean (SD) adalimumab trough level for MSB11022 and reference adalimumab was 8,490 (2,291) ng/mL and 7,570 (3,169) ng/mL, respectively, in ADA-negative patients, and 5,070 (3,657) ng/mL and 5,050 (3,514) ng/mL, respectively, in ADA-positive patients. No meaningful differences in ACR20 response rates were reported at scheduled visits up to week 52 when looking separately at ADA-positive and ADA-negative status (Online Resource 6a).
For MSB11022 and reference adalimumab, the mean trough serum concentrations at week 24 were 6,380 ng/mL and 6,550 ng/mL, and at week 52, these were 5,610 ng/mL and 5,330 ng/mL, respectively, with similar concentrations across groups at all time points up to week 52. The presence of ADA had an impact on adalimumab trough concentrations, where ADA-positive subjects had lower trough concentrations compared with ADA-negative subjects; this trend was similar for both MSB11022 and reference adalimumab (Online Resource 6b). The influence of ADA on PK parameters was similar across treatment groups. Lower mean trough concentrations were also observed in the ADA-positive subjects who tested NAb-positive compared with those who tested NAb-negative (data not shown).
Other safety endpoints
The incidence of TEAEs up to week 52 was similar between the treatment arms (MSB11022: n = 83 [58.0%]; reference adalimumab: n = 93 [64.1%]; Table 2. A lower proportion of patients in the MSB11022 compared with the reference adalimumab treatment arm permanently discontinued treatment due to TEAEs (4.2% vs 9.7%). In the 4-month safety follow-up, only 6 patients in each arm experienced a TEAE; none of which were considered to be treatment-related. Few patients experienced an SAE during the treatment period or during the 4-month safety follow-up (Table 2). There was no notable imbalance between the treatment arms.
There were three deaths reported in the study. One patient died of unknown causes prior to randomization. One patient died in the reference adalimumab arm during the treatment period following arteriosclerosis in the coronary artery and myocardial ischemia; this was considered to be unrelated to the treatment. One patient died of unknown causes in the reference adalimumab arm during the 4-month safety follow-up. This was also considered to be unrelated to the treatment.
Fewer injection site reactions (ISRs) were reported in the MSB11022 arm compared with the reference adalimumab arm, 13 patients (9.1%) reported 56 ISRs with MSB11022 and 33 patients (22.8%) reported 298 ISRs with reference adalimumab. A large proportion of reported ISRs concentrated on a small number of subjects experiencing multiple repeat ISRs. The most commonly reported ISRs were erythema, pruritus, and pain, which accounted for more than half of all reported events.
There was no notable pattern in terms of AESIs, TEAEs, or ISRs between the treatment arms with regard to ADA status or NAb status.
The results of this study indicate that MSB11022 (acetate formulation) and reference adalimumab are similar with regard to safety, immunogenicity, and efficacy in patients with moderately-to-severely active RA while on stable treatment with methotrexate. This patient population is the most robustly studied population in phase 3 studies of adalimumab in RA  and represents a large proportion of patients receiving adalimumab. RA is also an example of a sensitive setting to investigate potential differences in immunogenicity, given the immunogenicity observed with TNF inhibitors in RA . These results add to the evidence of similarity between the molecule MSB11022 and reference adalimumab, as demonstrated previously in patients with psoriasis in the AURIEL-PsO study  and provide data for the acetate formulation in this disease population.
There were few treatment-emergent hypersensitivity reactions up to week 52, and no differences were observed between treatment arms. The incidence of TEAEs was comparable up to week 52 and at the 4-month follow-up across both treatment groups, and no new safety signals were observed. A trend towards reduced incidence of ISRs was observed with MSB11022 compared with the reference product. However, this result was skewed by the fact that a small number of patients experienced a high number of events.
The results for the efficacy endpoints consistently indicated similarity between MSB11022 and the reference product, with similar proportions of patients in the MSB11022 and reference adalimumab arms achieving ACR20 at week 12. This similarity was maintained at all scheduled visits up to week 52. Similar efficacy between MSB11022 and reference adalimumab in RA was further confirmed with DAS28-ESR, CDAI and SDAI scores, and also in evaluations of QoL. This supports the findings of the AURIEL-PsO study, which demonstrated that MSB11022 was clinically similar to reference adalimumab in terms of the efficacy endpoints .
An evaluation of immunogenicity is a key part of the clinical assessment of biosimilars. In this study, there were no clinically meaningful differences in the incidence of ADAs and NAbs between treatment arms up to week 52. This is consistent with the results reported in the AURIEL-PsO study . Of note, the incidence of ADAs and NAbs was considerably higher than was reported in the pivotal studies for reference adalimumab . This may reflect the use of more sensitive and drug-tolerant assays than were used in earlier studies  and is consistent with other recent adalimumab studies . Similar to the AURIEL-PsO study, in which PASI75 was the primary efficacy parameter, no differences in efficacy as measured by ACR20 response rates were reported between ADA-positive and ADA-negative patients in AURIEL-RA. The difference in ACR20 response rate observed in patients stratified by ADA status is comparable (Online Resource 6a). This observation stands out when compared with published data [26, 27] and may be due to the highly sensitive and drug-tolerant assay used for detecting ADAs. While adalimumab mean trough levels in ADA-negative patients are higher than for ADA-positive patients in both arms in our study, published data have indicated that adalimumab trough levels of 5–8 μg/mL are sufficient to reach adequate clinical response in patients with RA, and clinical effect was observed even in patients with adalimumab concentrations as low as 3 μg/mL .
The main limitation of this study is that it is descriptive only and was not powered to show equivalence between MSB11022 and reference adalimumab for any endpoint. In general, safety and tolerability studies are not powered due to the statistical challenges in analyzing safety and tolerability events, which cannot all be anticipated when designing a trial. Therefore, the European Medicines Agency recommends that, in most trials, safety implications are best addressed by applying descriptive statistical methods to the data, supplemented by calculation of CIs wherever this aids interpretation . Similar concerns around uncertainty apply to studying immunogenicity  and its effect on safety, PK parameters, and efficacy [31, 32]. In addition, no switch arm was included, so no data on the impact of switching from reference adalimumab to MSB11022 in RA are available.
In conclusion, MSB11022 and reference adalimumab are comparable in terms of safety, immunogenicity, and efficacy. Furthermore, the results of the AURIEL-RA study in patients with RA are consistent with the results of the AURIEL-PsO study in patients with psoriasis, despite differences in the formulations tested in the two studies. This supports the overall biosimilarity concept for the MSB11022 molecule.
