[PMID: 38514505 PMCID: PMC11052879 DOI: 10.1007/s12325-024-02809-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Accepted: 02/01/2024] [Indexed: 03/23/2024]
Abstract
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.

Vyas J, Johns JR, Ali FM, Singh RK, Ingram JR, Salek S, Finlay AY. A systematic review of 454 randomized controlled trials using the Dermatology Life Quality Index: experience in 69 diseases and 43 countries. Br J Dermatol 2024; 190:315-339. [PMID: 36971254 DOI: 10.1093/bjd/ljad079] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Revised: 01/31/2023] [Accepted: 03/14/2023] [Indexed: 02/18/2024]
Abstract
BACKGROUND Over 29 years of clinical application, the Dermatology Life Quality Index (DLQI) has remained the most used patient-reported outcome (PRO) in dermatology due to its robustness, simplicity and ease of use. OBJECTIVES To generate further evidence of the DLQI's utility in randomized controlled trials (RCTs) and to cover all diseases and interventions. METHODS The methodology followed PRISMA guidelines and included seven bibliographical databases, searching articles published from 1 January 1994 until 16 November 2021. Articles were reviewed independently by two assessors, and an adjudicator resolved any opinion differences. RESULTS Of 3220 screened publications, 454 articles meeting the eligibility criteria for inclusion, describing research on 198 190 patients, were analysed. DLQI scores were primary endpoints in 24 (5.3%) of studies. Most studies were of psoriasis (54.1%), although 69 different diseases were studied. Most study drugs were systemic (85.1%), with biologics comprising 55.9% of all pharmacological interventions. Topical treatments comprised 17.0% of total pharmacological interventions. Nonpharmacological interventions, mainly laser therapy and ultraviolet radiation treatment, comprised 12.2% of the total number of interventions. The majority of studies (63.7%) were multicentric, with trials conducted in at least 42 different countries; 40.2% were conducted in multiple countries. The minimal clinically importance difference (MCID) was reported in the analysis of 15.0% of studies, but only 1.3% considered full score meaning banding of the DLQI. Forty-seven (10.4%) of the studies investigated statistical correlation of the DLQI with clinical severity assessment or other PRO/quality of life tools; and 61-86% of studies had within-group scores differences greater than the MCID in 'active treatment arms'. The Jadad risk-of-bias scale showed that bias was generally low, as 91.8% of the studies had Jadad scores of ≥ 3; only 0.4% of studies showed a high risk of bias from randomization. Thirteen per cent had a high risk of bias from blinding and 10.1% had a high risk of bias from unknown outcomes of all participants in the studies. In 18.5% of the studies the authors declared that they followed an intention-to-treat protocol; imputation for missing DLQI data was used in 34.4% of studies. CONCLUSIONS This systematic review provides a wealth of evidence of the use of the DLQI in clinical trials to inform researchers' and -clinicians' decisions for its further use. Recommendations are also made for improving the reporting of data from future RCTs using the DLQI.

[PMID: 37257054 DOI: 10.1093/ajhp/zxad120] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Indexed: 06/02/2023] Open
Abstract
PURPOSE The impact of the market entry of adalimumab biosimilars on clinical practices and specialty pharmacies is explained. A roadmap is also provided for how pharmacists can successfully navigate this landscape. SUMMARY Biosimilars have previously been introduced as a mechanism to help curb biologic expenditures, with biosimilars undergoing an abbreviated regulatory approval process that focuses on biosimilarity and generating product competition. Adalimumab is currently the leading product in the biologics market, generating approximately $20 to $30 billion in sales worldwide consecutively from 2019 to 2021. Many adalimumab biosimilars are slated to enter the market in 2023 and become available for patient use. However, compared to other biosimilars, adalimumab biosimilars have several unique considerations, such as interchangeability and concentration, that will impact pharmacy practices and workflows. Because pharmacists embedded in clinical practices and specialty pharmacies will be significantly involved in the processes relating to adalimumab biosimilar implementation, adoption, and use, a primer on understanding the various adalimumab biosimilar products available and considerations surrounding these products with regard to workflow and patient use is critical. Several resources are also provided to help pharmacists successfully navigate the adalimumab biosimilar landscape. CONCLUSION The biosimilar landscape continues to evolve, and 2023 will see the launch of several adalimumab biosimilar products, which vary with regard to formulation, concentration, and interchangeability status. Pharmacists are well positioned to educate providers and patients about this landscape and help implement an efficient workflow to support adalimumab biosimilar adoption and use.

GP2017-HCF, a high concentration formulation, demonstrates similar pharmacokinetics, immunogenicity and safety to GP2017, an approved adalimumab biosimilar. Expert Opin Biol Ther 2023; 23:749-758. [PMID: 36039657 DOI: 10.1080/14712598.2022.2117546] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Accepted: 08/23/2022] [Indexed: 11/04/2022]
Abstract
BACKGROUND GP2017 is an adalimumab biosimilar. The objective of this study is to compare the pharmacokinetics (PK) of GP2017 in its approved formulation and GP2017-high concentration formulation (HCF) in a randomized, double-blind, two-arm PK bridging study. RESEARCH DESIGN AND METHODS Healthy male subjects received a single 40 mg subcutaneous injection of either GP2017-HCF (n = 162) or GP2017 (n = 168). PK, safety, and immunogenicity were assessed over 72 days post-injection. RESULTS The 90% confidence intervals [CIs] of geometric mean ratios between GP2017-HCF and GP2017 for Cmax, AUC0-inf, AUC0-360 and AUC0-last were within the pre-defined margin of 0.80 to 1.25; thus, PK comparability between GP2017-HCF and GP2017 was demonstrated. Subgroup analysis of PK comparability by anti-drug antibody (ADA) subpopulation showed that the 90% CIs of geometric mean ratios between GP2017-HCF and GP2017 for Cmax, AUC0-inf, AUC0-360 and AUC0-last were within the margin of 0.80 to 1.25 in ADA-positive and ADA-negative subjects. The proportions of subjects with positive ADA responses and with neutralizing antibodies were comparable between the GP2017-HCF and GP2017 groups. GP2017-HCF and GP2017 were well tolerated, and there were no reports of deaths or other serious adverse events. CONCLUSION Results show PK comparability between GP2017-HCF and GP2017 and comparable safety and tolerability.

SAUDI JOURNAL OF MEDICINE & MEDICAL SCIENCES 2023; 11:150-156. [PMID: 37252022 PMCID: PMC10211417 DOI: 10.4103/sjmms.sjmms_517_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/15/2022] [Revised: 11/15/2022] [Accepted: 03/13/2023] [Indexed: 05/31/2023]
Abstract
Background In patients with rheumatoid arthritis (RA), hematological indices and ratios have been reported to be related to the severity of illness, and thus could potentially be useful determinants of quality of life (QoL). Objective To evaluate the association between hematological indices or ratios, which serve as biomarkers of disease activity, and the QoL of RA patients. Materials and Methods This study was carried out in the Rizgary Teaching Hospital in the Kurdistan region of Iraq between December 01, 2021, and March 31, 2022. All female patients with a confirmed diagnosis of RA and aged ≥18 years were included. Data relating to the disease activity score (DAS-28), biochemical measurements of the profile, and hematological indices and ratios were assessed. The QoL of each patient was assessed using the Quality of Life-Rheumatoid Arthritis II (QoL-RA II) and the World Health Organization-Quality of Life (WHOQOL-BREF) scales. Results A total of 81 participants were included, with a median disease duration of 9 years. The median values of the hematological indices were as follows: mean corpuscular volume, 80 fL; platelet count 282 × 103/mm3; mean platelet volume, 9.7 fL; neutrophil-to-lymphocyte ratio, 2.76; and platelet-to-lymphocyte ratio, 170.5. In six of the eight domains of the QoL-RA II scale, the median score was ≤5, indicating poor QoL. The transformed scores of WHOQOL-BREF domains were <50. Multivariate regression analysis showed significant inverse correlations between plateletcrit and the health domains. The area under the curve of the physical, psychological, and environmental domains was <0.5 at a cutoff value of plateletcrit of 0.25. Conclusions In RA patients, hematological indices and ratios could serve as a QoL assessment tool, particularly plateletcrit, as higher plateletcrit (≥0.25) were found to negatively impact the physical health, psychological, and environmental domains.

Comparison of Efficacy and Safety of Original and Biosimilar Adalimumab in Active Rheumatoid Arthritis in a Real-World National Cohort. MEDICINA (KAUNAS, LITHUANIA) 2022; 58:medicina58121851. [PMID: 36557052 PMCID: PMC9784493 DOI: 10.3390/medicina58121851] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/21/2022] [Revised: 12/08/2022] [Accepted: 12/14/2022] [Indexed: 12/23/2022]
Abstract
Background and Objectives: Real-world evidence should reflect the evidence obtained from controlled trials; therefore, the study aimed to compare biosimilar adalimumab (bADA) to original adalimumab (oADA) in terms of efficacy and safety in a real-life national cohort of rheumatoid arthritis (RA) patients. Materials and Methods: The following study is a prospective observational study in which we analyzed patients treated with reimbursed biologics from the Romanian Registry of Rheumatic Diseases (RRBR). RA cases must fulfill the 2010 classification criteria, as well as specific inclusion and exclusion criteria. The RRBR database was queried for all RA patients starting oADA or bADA (FKB327, GP2017, MSB11022, SB5 available) from 2 May 2019 (the first bADA initiation) until 26 March 2022 (study search date). Results: The study included 441 patients who started oADA (48.3%) or bADA (51.7%) in the same time period. At baseline, patients starting bADA had a significantly higher mean age and lower prevalence of women. After the first six months of treatment, there were no significant differences between the oADA and bADA regarding rates of Boolean (15.0% vs. 12.3%, p = 0.401), DAS28-CRP (32.4% vs. 34.2%, p = 0.686) and SDAI (16.4% vs. 14.0%, p = 0.483) remission rates. There were 107 cases of adverse events (AE): 81.3% on oADA and 18.7% on bADA. Notably, 51.4% of AE were infections. Regarding severity, 49.5% of AEs were mild, 34.6% were moderate, and 15.9% were severe. Conclusion: Biosimilar adalimumab showed similar efficacy and safety to original adalimumab after the first six months of treatment in RA patients from a national registry.

Abstract
Purpose This review aims to provide an overview of the impact of TNFis biosimilars, with marketing authorization, in patient-reported outcome measures (PROMs) scores and explore how PROMs endpoints might add value in biosimilars uptake in RA patients. Patients and Methods A comprehensive search of Medline, Scopus, Lilacs, and CINAHL databases was performed for papers published between January 2012 and December 2021. For inclusion, studies had to be prospective, published in a peer-reviewed journal, published in English or Spanish language; studies using PROMs as an outcome measure. After screening title and abstracts and assessing the remaining full texts fulfilling the inclusion criteria, 31 papers were used in this narrative review. Results PROMs were used as secondary outcomes in included studies. The most frequently employed domains to assess biosimilar efficacy include physical function, patient global assessment (PtGA), health-related quality of life (HRQoL), and fatigue. The results of randomized clinical trials uniformly showed that mean change in PROMs scores is comparable between biosimilar and reference biologic treatment groups. However, open-label and real-world studies revealed high rates of discontinuation of therapy, mainly for subjective worsening of disease activity or non-specific adverse events. Even without objective clinical evidence of inflammation, patients who are considered to have active disease (higher scores on PtGA) have higher discontinuation rates of biosimilars. The available information suggests that the nocebo effect is the most likely cause for the discontinuation of biosimilars. Conclusion There is scarce literature surrounding the impact of biosimilars in PROMs, especially in open-label studies. In real-life studies, biosimilars have a higher discontinuation rate than reference products. TNFis biosimilars treatment efficacy in RA depends on disease activity and other factors such as PtGA and fatigue. The nocebo effect is the best explanation for biosimilar’s discontinuation.
