The Expiry of Humira^® Market Exclusivity and the Entry of Adalimumab Biosimilars in Europe: An Overview of Pricing and National Policy Measures.

ABSTRACT: Background: From October 2018, adalimumab biosimilars could enter the European market. However, in some countries, such as Netherlands, high discounts reported for the originator product may have influenced biosimilar entry. Objectives: The aim of this paper is to provide a European overview of (list) prices of originator adalimumab, before and after loss of exclusivity; to report changes in the reimbursement status of adalimumab products; and discuss relevant policy measures. Methods: Experts in European countries received a survey consisting of three parts: 1) general financing/co-payment of medicines, 2) reimbursement status and prices of originator adalimumab, and availability of biosimilars, and 3) policy measures related to the use of adalimumab. Results: In May 2019, adalimumab biosimilars were available in 24 of the 30 countries surveyed. Following introduction of adalimumab biosimilars, a number of countries have made changes in relation to the reimbursement status of adalimumab products. Originator adalimumab list prices varied between countries by a factor of 2.8 before and 4.1 after loss of exclusivity. Overall, list prices of originator adalimumab decreased after loss of exclusivity, although for 13 countries list prices were unchanged. When reported, discounts/rebates on originator adalimumab after loss of exclusivity ranged from 0% to approximately 26% (Romania), 60% (Poland), 80% (Denmark, Italy, Norway), and 80-90% (Netherlands), leading to actual prices per pen or syringe between €412 (Finland) and €50 - €99 (Netherlands). To leverage competition following entry of biosimilar adalimumab, only a few countries adopted measures specifically for adalimumab in addition to general policies regarding biosimilars. In some countries, a strategy was implemented even before loss of exclusivity (Denmark, Scotland), while others did not report specific measures. Conclusion: Even though originator adalimumab is the highest selling product in the world, few countries have implemented specific policies and practices for (biosimilar) adalimumab. Countries with biosimilars on the market seem to have competition lowering list or actual prices. Reported discounts varied widely between countries.

Project description:BACKGROUND:This double-blind, randomized, 78-week study evaluated the efficacy, safety, immunogenicity, pharmacokinetics, and pharmacodynamics of PF-06410293, a candidate adalimumab biosimilar, versus adalimumab reference product (Humira®) sourced from the EU (adalimumab-EU) in biologic-naïve patients with active rheumatoid arthritis (RA) despite methotrexate (MTX) (10-25 mg/week). We report results for the first 26 weeks of treatment. METHODS:Patients with active RA (N = 597) were randomly assigned (1:1) to PF-06410293 or adalimumab-EU, while continuing with MTX treatment. The primary endpoint was American College of Rheumatology 20% improvement (ACR20) at week 12. Therapeutic equivalence was concluded if the two-sided 95% confidence interval (CI) for the ACR20 difference between the two arms was entirely contained within the symmetric equivalence margin (±14%). Additionally, a two-sided 90% CI was calculated by using an asymmetric equivalence margin (-12%, 15%). Secondary efficacy endpoints to week 26 included ACR20/50/70, change from baseline Disease Activity Score based on high-sensitivity C-reactive protein [DAS28-4(CRP)], European League Against Rheumatism (EULAR) response, DAS28-4(CRP) of less than?2.6, and ACR/EULAR remission. QuantiFERON-TB testing was performed at screening and week 26. RESULTS:Patients (78.7% of whom were female and whose mean age was 52.5 years) had a mean baseline RA duration of 6.8 years. The mean baseline DAS28-4(CRP) values were 5.9 (PF-06410293) and 6.1 (adalimumab-EU). The observed week-12 ACR20 values were 68.7% (PF-06410293) and 72.7% (adalimumab-EU) in the intention-to-treat population. With non-responder imputation, the treatment difference in week-12 ACR20 was -2.98% and corresponding CIs-95% CI (-10.38%, 4.44%) and 90% CI (-9.25%, 3.28%)-were entirely contained within the equivalence margins (symmetric and asymmetric, respectively). The secondary efficacy endpoints were similar between arms. Over 26 weeks, injection-site reactions occurred in 1.7% versus 2.0%, hypersensitivity events in 4.4% versus 8.4%, pneumonia in 0.7% versus 2.0%, and opportunistic infections in 2.4% versus 1.7% in the PF-06410293 and adalimumab-EU arms, respectively. One death due to myocardial infarction occurred (adalimumab-EU arm). Rates of anti-drug antibody incidence were 44.4% (PF-06410293) and 50.5% (adalimumab-EU). CONCLUSIONS:The study results demonstrate that efficacy, safety, and immunogenicity of PF-06410293 and adalimumab-EU were similar during the first 26 weeks of treatment in patients with active RA on background MTX. TRIAL REGISTRATION:ClinicalTrials.gov Identifier: NCT02480153 . First posted on June 24, 2015; EU Clinical Trials Register EudraCT number: 2014-000352-29 . Start date: October 27, 2014.

Project description:AimsThe aim of the study was to compare the pharmacokinetics (PK), safety and tolerability of the proposed adalimumab biosimilar MSB11022 (Merck) with Humira(®) (AbbVie), sourced from both the US (US reference product [US-RP]) and Europe (European reference medicinal product [EU-RMP]).MethodsIn this phase 1 double-blind, parallel group trial (EMR200588-001), 213 healthy volunteers were randomized 1 : 1 : 1 to receive a single dose (40 mg) of MSB11022, US-RP or EU-RMP in order to achieve 80% power assuming a 5% difference among groups and a 10% dropout rate. Following a preplanned blinded sample size re-assessment after more than 50% of the originally planned subjects had been observed, the sample size was increased to 237 (79 per arm) to ensure 213 completers. Primary PK endpoints analyzed by non-compartmental methods, were area under the curve (AUC) from time 0 extrapolated to infinity (AUC(0,∞)), maximum observed concentration (Cmax ), and AUC from time 0 to the last quantifiable concentration (AUC(0,tlast )). PK equivalence was declared if the 90% CI for the test : reference ratio lay within the 80-125% equivalence margin. Bioequivalence was demonstrated if all three PK parameters met the PK equivalence criteria. Safety and tolerability were also evaluated.ResultsMean serum concentration-time profiles for the three treatments were similar. MSB11022 demonstrated PK equivalence to US-RP and EU-RMP for all primary endpoints. The geometric means of AUC(0,∞), Cmax and AUC(0,tlast ) following a single dose of MSB11022 were 2276.05 μg ml(-1) h, 3.44 μg ml(-1) and 1983.90 μg ml(-1) h, respectively. Adverse events (AEs) were similar across all groups, with treatment-emergent AEs (TEAEs) reported by 62.8%, 56.3% and 62.0% of subjects within the MSB11022, US-RP and EU-RMP groups, respectively. Most of the TEAEs were considered mild and unrelated to study drug. No deaths or severe AEs related to the study drug were reported.ConclusionsBioequivalence between MSB11022, US-RP and EU-RMP was demonstrated. Safety, tolerability and immunogenicity profiles were similar between subjects receiving MSB11022 and US-RP or EU-RMP. These data support the further clinical evaluation of MSB11022 as a proposed biosimilar of adalimumab.

Project description:ImportanceThe efficacy of adalimumab biosimilars is similar to that of brand-name adalimumab (Humira, hereinafter originator) in clinical trials. However, limited knowledge about real-world data exists for adalimumab biosimilars.ObjectiveTo assess the outcomes following a mandatory nonmedical switch from adalimumab originator to adalimumab biosimilars in patients with psoriasis.Design, setting, and participantsThis cohort study assesses the outcomes following a switch from adalimumab originator to an adalimumab biosimilar. Patients in the Biological Treatment in Danish Dermatology (DERMBIO) registry, a Danish nationwide registry of all patients treated with biologics (including biosimilars) for psoriasis since 2007, were assessed for eligibility. All patients who switched from adalimumab originator to an adalimumab biosimilar between November 1, 2018, and May 1, 2019, were included in the adalimumab biosimilar cohort. All patients with a visit between May 1, 2017, and November 1, 2017, treated with adalimumab originator were included in the adalimumab originator cohort. Data were analyzed from June 1, 2020, to October 10, 2021.ExposureSwitch from adalimumab originator to an adalimumab biosimilar.Main outcomes and measuresThe primary outcome was 1-year drug retention in patients switching to adalimumab biosimilars compared with patients treated with adalimumab originator. Crude and adjusted retention rates for the adalimumab biosimilar cohort were compared with the adalimumab originator cohort with Cox proportional hazards regression using robust variance.ResultsA total of 348 patients were included in the adalimumab biosimilar cohort (mean [SD] age, 52.2 [13.6] years; 251 [72.1%] male) and 378 patients in the adalimumab originator cohort (mean [SD] age, 51.1 [14.1] years; 272 [72.0%] male). The 1-year drug retention rates were 92.0% (95% CI, 89.0%-94.9%) for the adalimumab biosimilar cohort and 92.1% (95% CI, 89.4%-94.8%) for the adalimumab originator cohort. Similar hazard ratios were observed between the 2 cohorts. The crude hazard ratios were 1.02 (95% CI, 0.61-1.70; P = .94) for all causes of drug discontinuation, 0.82 (95% CI, 0.39-1.73; P = .60) for insufficient effect, and 1.41 (95% CI, 0.52-3.77; P = .50) for adverse events for the adalimumab biosimilar cohort when compared with the adalimumab originator cohort.Conclusions and relevanceIn this cohort study from Denmark, a nonmedical switch from adalimumab originator to adalimumab biosimilars was not associated with drug retention.

Project description:BackgroundPharmaceutical spending has been increasing rapidly for years and is higher than ever before. To control the rising costs, countries are implementing regulatory frameworks such as (internal) reference pricing, price cuts or generics substitution. Internal reference pricing establishes a reference price within a country which serves as the maximum level of reimbursement for a group of pharmaceuticals. Price setting in the German market is especially relevant for many European countries, which use Germany as a reference country for their own price setting.MethodsWe evaluate pharmaceutical price dynamics for not reference priced pharmaceuticals (NRPs) as well as for reference priced pharmaceuticals (RPs) in Germany-referring to the internal reference price system. 64,862 medication packs have been extracted from the German pharmaceutical pricing register Lauer-Taxe. For each pack, we extracted detailed data on the company, manufacturer rebates, pharmacy retail prices, reference prices, co-payments, import quotas, and discount agreements. We then investigated price setting and dynamics of NRPs vs. RPs for all 14 indication areas by ATC code level 1.ResultsThe average manufacturer price per pack was 604.84€ for NRPs and 112.11€ for RPs. Similar differences were found for the wholesale price and the pharmacy retail price. The reference price was-as expected-0.00€ for NRPs, and 154.40€ for RPs. NRP packs were imported in 42.38%, while RP packs were imported only in 24.62%. Highest average pharmacy retail prices could be found in the therapeutic areas 'antineoplastic and immunomodulating agents' (1711.47€), 'systemic hormonal preparations' (1331.95€), and 'blood and blood forming organs' (1260.58€). We detected high fluctuations in pharmacy retail prices per indication, as well as for reference prices per indication. The indications with the highest number of reference price regulated medical packs are 'cardiovascular system', 'musculo-skeletal system', and 'nervous system'. Highest co-payments were found in the indications 'antineoplastic and immunomodulating agents', 'blood and blood forming organs', and 'antiinfectives for systemic use'.ConclusionPrice setting and price dynamics vary substantially between NRP and RP medication packs. Further, we saw major differences across all indication areas as well as when comparing medication packs launched by top 20 pharma companies vs. the rest.
