Switching Between Adalimumab Reference Product and BI 695501 in Patients with Chronic Plaque Psoriasis (VOLTAIRE-X): A Randomized Controlled Trial.

ABSTRACT:

Background

BI 695501 is an FDA-approved biosimilar to adalimumab reference product (RP). VOLTAIRE-X was a randomized clinical trial to assess outcomes with a biosimilar monoclonal antibody in line with the FDA requirements for designation as an 'interchangeable' biosimilar.

Objective

The aim of this study was to assess whether multiple switches between adalimumab RP and BI 695501 lead to equivalent pharmacokinetics and a similar safety and immunogenicity profile compared with continuous adalimumab RP.

Methods

We conducted a phase III, double-blind, randomized controlled trial between July 19, 2017, and April 16, 2019. There were 49 investigational sites across Europe and North America. Of 323 screened patients with moderate-to-severe chronic plaque psoriasis, 259 were treated with adalimumab RP during the run-in period. Of these, 118 and 120 were randomized to the continuous or switching arms, respectively. Interventions consisted of a run-in period with adalimumab RP 80 mg subcutaneously (SC) on Day 1, then 40 mg SC every other week (EOW) Weeks 2-12. Patients were then randomized to receive adalimumab RP 40 mg EOW Weeks 14-48 (continuous arm) or BI 695501 40 mg Weeks 14 and 16, adalimumab RP 40 mg Weeks 18 and 20, and BI 695501 40 mg EOW Weeks 22 to 48 (switching arm); all interventions were given SC. Primary endpoints were pharmacokinetics parameters, area under the plasma concentration-time curve (AUC_τ,30-32) and maximum observed drug plasma concentration (C_max,30-32), measured after the third switch during the Week 30-32 dosing interval.

Results

238 patients (mean [standard deviation] age 44.9 [13.8]; 66.0% male) were treated in the switching (n = 118) or continuous arms (n = 120). Adjusted mean C_max,30-32 was 7.08 and 7.00 μg/mL in the switching and continuous treatment arms, respectively; adjusted mean AUC_τ,30-32 was 2025.8 and 1925.9 μg h/mL. Point estimate for mean ratio for AUC_τ,30-32 was 105.2% (90.2% confidence interval [CI] 96.6-114.6), and 101.1% (90.2% CI 93.3-109.7) for C_max,30-32. Both CIs were within a predefined bioequivalence range of 80.0-125.0%. Treatment-emergent adverse events led to discontinuation in 0.8% and 1.7% of patients in the switching and continuous treatment arms, and Psoriasis Area and Severity Index (PASI) scores were highly similar in the two arms across the entire trial period.

Conclusions

Pharmacokinetic equivalence was demonstrated, with highly similar efficacy and immunogenicity, and comparable safety observed in patients with chronic plaque psoriasis who received either adalimumab RP continuously or who switched between adalimumab RP and BI 695501.

Project description:Psoriasis affects 1-3% of the population, in some people causing changes to the nails and joints in addition to skin lesions. We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of systemic drug treatments, topical drug treatments, and non-drug treatments (other than ultraviolet light) for chronic plaque psoriasis? What are the effects of ultraviolet light treatments for chronic plaque psoriasis? What are the effects of combined treatment with drugs plus ultraviolet light on chronic plaque psoriasis? What are the effects of combined systemic plus topical drug treatments for chronic plaque psoriasis? We searched: Medline, Embase, The Cochrane Library, and other important databases up to August 2007 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). We found 122 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. In this systematic review we present information relating to the effectiveness and safety of the following interventions: acupuncture, adding calcipotriol (topical) to psoralen plus ultraviolet light A or ultraviolet light B, adding oral retinoids to psoralen plus ultraviolet A (PUVA), alefacept, balneotherapy, ciclosporin, dithranol, T cell-targeted therapies, cytokine blocking agents, emollients (alone or plus ultraviolet light B), etanercept, fish oil supplementation, fumaric acid derivatives, Goeckerman treatment, heliotherapy, infliximab, Ingram regimen, keratolytics (salicylic acid, urea), leflunomide, methotrexate, oral pimecrolimus, phototherapy plus balneotherapy, psoralen plus ultraviolet A, psychotherapy, oral retinoids (alone or with ultraviolet light B), systemic drug treatments plus topical vitamin D derivatives, tars, tazarotene, topical corticosteroids (alone or plus oral retinoids), topical Vitamin D derivatives, ultraviolet light A, and ultraviolet light B.

Project description:BackgroundMSB11022 is a proposed adalimumab biosimilar.ObjectivesTo compare the efficacy, safety and immunogenicity of MSB11022 with reference adalimumab.MethodsAURIEL-PsO was a double-blind randomized controlled equivalence trial, in which patients with moderate-to-severe chronic plaque-type psoriasis were randomized 1 : 1 to MSB11022 or reference adalimumab. The primary end point was ≥ 75% improvement in Psoriasis Area and Severity Index (PASI 75) at week 16, with a prespecified equivalence interval of ± 18%. Patients with a ≥50% improvement in PASI at week 16 were eligible to enter a double-blind extension period: patients receiving MSB11022 continued treatment, and patients receiving reference adalimumab were rerandomized 1 : 1 either to continue reference adalimumab or to switch to MSB11022. Other efficacy end points and safety, immunogenicity and pharmacokinetic parameters were evaluated at scheduled visits up to weeks 52 (efficacy and immunogenicity), 54 and 66 (safety).ResultsIn total, 443 patients were randomized. The difference in PASI 75 response rates at week 16 between the treatment arms was -1·9%, and the 95% confidence interval (-7·8% to 4·1%) was within the prespecified equivalence interval. No notable difference in the incidence of treatment-emergent adverse events was observed between treatment arms up to the end of the trial, and no new safety signals were observed. Following treatment switch at week 16, no clinically meaningful differences in safety or immunogenicity were seen between treatment arms through to the end of the observation period.ConclusionsTherapeutic equivalence between MSB11022 and reference adalimumab was demonstrated. AURIEL-PsO provides evidence to support the similarity of both products with regard to efficacy, safety and immunogenicity. What's already known about this topic? Adalimumab is a fully human antitumour necrosis factor-α monoclonal antibody, indicated for the treatment of multiple inflammatory disorders, including psoriasis, psoriatic arthritis, rheumatoid arthritis, inflammatory bowel diseases and ankylosing spondylitis. MSB11022 is a proposed adalimumab biosimilar that has shown structural and functional similarity to the reference product in an extensive analytical comparability exercise. MSB11022 has demonstrated bioequivalence and comparable safety and immunogenicity profiles in a phase I study in healthy volunteers. What does this study add? This phase III study confirmed equivalent efficacy for MSB11022 and reference adalimumab in patients without any immunomodulation comedication in moderate-to-severe chronic plaque-type psoriasis at week 16. The efficacy, safety and immunogenicity of MSB11022 and reference adalimumab were similar over the respective observation periods (week 52 for efficacy and immunogenicity, week 66 for safety). A switch from reference adalimumab to MSB11022 at week 16 did not impact efficacy, safety or immunogenicity.

Project description:BackgroundAdalimumab (ADA) (Humira® , AbbVie Inc., U.S.A.) is approved by the European Medicines Agency for children aged ≥ 4 years with severe plaque psoriasis.ObjectivesTo evaluate the long-term efficacy and safety of ADA in children with severe plaque psoriasis.MethodsResults are presented from the 52-week long-term extension (LTE) of the randomized, double-blind, double-dummy, phase III trial, in children with severe plaque psoriasis (results from prior periods have been published). Patients aged ≥ 4 and < 18 years were randomized 1 : 1 : 1 to ADA 0·8 mg kg-1 (40 mg maximum) or 0·4 mg kg-1 (20 mg maximum) every other week or to methotrexate (MTX) 0·1-0·4 mg kg-1 (25 mg maximum) weekly. The 16-week initial treatment (IT) period was followed by a 36-week withdrawal period and a 16-week retreatment period. Patients could enter the LTE at prespecified time points to receive ADA 0·8 mg kg-1 (blinded or open label) or ADA 0·4 mg kg-1 (blinded), or to remain off treatment. Efficacy is reported for patient groups according to doses received in the IT and LTE periods.ResultsOf the 114 patients randomized in the IT period, 108 entered the LTE (n = 36 in each group); 93 received ADA 0·8 mg kg-1 . Efficacy (≥ 75% improvement from baseline in Psoriasis Area and Severity Index) was maintained or improved from entry to the end of the LTE: MTX(IT)/ADA 0·8(LTE) 31-86% of patients; ADA 0·4(IT)/0·4 or 0·8(LTE) 28-47%; ADA 0·8(IT)/0·8(LTE) 50-72%. No serious infections occurred in the LTE.ConclusionsAfter 52 weeks of long-term ADA treatment in children aged 4-18 years with severe plaque psoriasis, disease severity was reduced and maintained or further improved, as demonstrated by efficacy outcomes. No new safety risks were identified. What's already known about this topic? The results from the first three periods of this phase III trial in children aged 4-18 years with severe plaque psoriasis suggest that adalimumab is a safe and efficacious treatment option in this population. What does this study add? This is the first study to evaluate long-term treatment of adalimumab in children with severe psoriasis, and the first to evaluate switching from methotrexate to adalimumab in this population.

Project description:BackgroundThis phase 3 trial is the first to evaluate the efficacy and safety of treatment with the systemic TNF-α inhibitor, adalimumab, for Chinese patients with moderate-to-severe plaque psoriasis.MethodsIn the 12-week, double-blind, placebo-controlled Period A, patients were randomized 4 : 1 to receive adalimumab 40 mg every-other-week (following a single 80 mg dose), or placebo every-other-week. In the subsequent 12-week, open-label, Period B, all patients received adalimumab 40 mg every-other-week starting at week 13, following a single, blinded dose at week 12 of adalimumab 80 mg or matching placebo (for patients receiving placebo or adalimumab in Period A respectively). In Period A, efficacy was analysed for all randomized patients and safety for all patients receiving ≥1 dose of the study drug.ResultsFor the 425 patients in this study (87 placebo; 338 adalimumab), a higher percentage randomized to adalimumab achieved the primary endpoint of ≥75% improvement from baseline in PASI score (PASI 75) at week 12: placebo 11.5% (10/87); adalimumab 77.8% (263/338; P < 0.001). Physician's Global Assessment of clear to minimal was achieved at week 12 by 14.9% placebo (13/87) and 80.5% adalimumab (272/338; P < 0.001). For patients who received adalimumab at any time during the study (All-adalimumab Population), treatment-emergent adverse events (AEs) were reported by 63.4%; the most common was upper respiratory infection (16.1%). Serious AEs were reported by 3.5% of the All-adalimumab Population, and serious infectious AEs by 1.2%, which include lung infection, pneumonia and tuberculosis [2 (0.5%) patients each]. There was one death (chronic heart failure).ConclusionIn these Chinese patients with moderate-to-severe psoriasis, a significantly greater percentage treated with adalimumab compared with placebo achieved efficacy endpoints at week 12 and efficacy was sustained to week 24. Safety results were consistent with the known adalimumab safety profile; no new safety signals were identified in the 24 weeks of treatment.
