As the Centers for Medicare and Medicaid Services (CMS) navigates the process of negotiating drug prices, it plans to compare the cost, safety, and effectiveness of each drug with its therapeutic alternatives. How CMS selects therapeutic alternatives is a consequential decision, and there remains uncertainty about their methodology. To understand the challenges CMS will face in selecting therapeutic alternatives, we developed a methodology that leverages clinical guidelines by US medical professional associations to identify potential therapeutic alternatives for etanercept (Enbrel), one of the first 10 drugs selected for Medicare price negotiation...

BACKGROUND AND AIMS: This study aimed to assess the comparative effectiveness of the etanercept (ETN) originator (Enbrel) and ETN biosimilar SB4 (Brenzys) as first-line treatment in patients with rheumatoid arthritis (RA), while also exploring the potential cost-savings associated with this approach in Australia. METHODS: Clinical data were obtained from the Optimising Patient outcomes in rheumatoLogy Australian real-world data set. Adult patients with RA who had initiated treatment with the ETN originator or biosimilar as their first-recorded biologic or targeted synthetic disease-modifying antirheumatic drug between 1 April 2017 and 31 December 2020 were included...

This study reviewed the evidence on the usability and preference of self-injection devices of SB4 and SB5 compared with the reference product injectors. METHODS: A systematic search was conducted in PubMed using the search string "(Imraldi OR Hadlima OR SB5 OR Benepali OR Brenzys OR SB4) AND (preference) AND (device)" covering the period from 28 January 2016 (first introduction of SB4) to 31 May 2022...

Rheumatoid arthritis (RA) is a complex autoimmune disease characterized by hyperactive immune cells within the joints, which leads to inflammation, bone degeneration, and chronic pain. For several decades, frontline immunomodulators such as the anti-tumor necrosis factor (TNF) biologics adalimumab (Humira), etanercept (Enbrel), and infliximab (Remicade) have successfully managed disease progression for many patients. However, over time, patients become refractory to these treatments requiring chronic disease to be managed with conventional and more problematic disease modifying antirheumatic drugs such as methotrexate and hydroxychloroquine, and corticosteroids...

Human urinary proteins are a goldmine of natural proteins a feature that simplifies their translation to biologics. Combining this goldmine together with the ligand-affinity-chromatography (LAC) purification method, proved a winning formula in their isolation. LAC specificity, efficiency, simplicity and inherent indispensability in the search for predictable and unpredictable proteins, is superior to other separation techniques. Unlimited amounts of recombinant cytokines and monoclonal antibodies (mAb) accelerated the "triumph"...

Background: Although with the application of etanercept biosimilars in the field of rheumatoid arthritis, the evidences of their efficacy, safety, and immunogenicity are still limited. We conducted this meta-analysis to evaluate the efficacy, safety and immunogenicity of etanercept biosimilars for treating active rheumatoid arthritis compared to reference biologics (Enbrel® ). Methods: PubMed, Embase, Central, and ClinicalTrials.gov were searched for randomized controlled trials of etanercept biosimilars treated in adult patients diagnosed with rheumatoid arthritis from their earliest records to 15 August 2022...

Complex immunosuppressive therapy is prescribed in medical practice to patients with glomerulonephritis to help them overcome symptoms and prevent chronic renal failure. Such an approach requires long-term systemic administration of strong medications, which causes severe side effects. This work shows the efficiency of polymer capsule accumulation (2.8 ± 0.4 µm) containing labeled etanercept (100 μg per dose) in the kidneys of mice. The comparison of injection into the renal artery and tail vein shows the significant superiority of the intra-arterial administration strategy...

Toxic epidermal necrolysis (TEN) is a rare yet life-threatening severe cutaneous adverse reaction (SCAR) to various causative agents, including medications, vaccinations, infections, and malignancies, in addition to some other uncommon external stimuli. TEN is characterized by the sudden appearance of generalizeddusky erythematous targetoid macules with a purpuric center, which coalesces to form bullae and flaccid blisters, leading to an eventual sheet-like epidermal detachment of all necrotic areas. Extensive epidermal denudation in TEN is usually accompanied by thermoregulatory impairment, insensible fluid loss, and hemodynamic instability...

The dominant method for generating Chinese hamster ovary (CHO) cell lines that produce high titers of biotherapeutic proteins utilizes selectable markers such as dihydrofolate reductase (Dhfr) or glutamine synthetase (Gs), alongside inhibitory compounds like methotrexate (MTX) or methionine sulfoximine (MSX), respectively. Recent work has shown the importance of asparaginase (Aspg) for growth in media lacking glutamine-the selection medium for Gs-based selection systems. We generated a Gs/Aspg double knockout CHO cell line and evaluated its utility as a novel dual selectable system via co-transfection of Gs-Enbrel and Aspg-Enbrel plasmids...

BACKGROUND: To analyze therapy adherence, safety, and outcome in adult patients with juvenile idiopathic arthritis (JIA) treated with the etanercept biosimilar Benepali® (Biogen Inc, Cambridge, USA). METHODS: Data from the prospective registry, JuMBO (Juvenile arthritis MTX/Biologics long-term Observation), were used for the analysis. JuMBO is a long-term observational cohort study. It follows adult patients with JIA who were formerly included in the national JIA biologic register (BiKeR Registry)...

Although several randomized clinical trials have confirmed that there is no difference in efficacy between etanercept and its biosimilar versions in the treatment of rheumatoid arthritis (RA), limited real-world evidence is available. We conducted a cohort study to compare the effectiveness and treatment persistence between the reference etanercept (ETN) and the biosimilar GP2015 in RA patients in a real-life setting. Adults with a diagnosis of RA who initiated treatment with ETN or GP2015, between January 2007 and December 2019, were included...

AIM: YLB113 biosimilar was evaluated in an open-label extension single-arm study to assess long-term safety, efficacy, and immunogenicity in patients with rheumatoid arthritis (RA). We also report post-hoc results on the incidence of injection-site reactions (ISRs) and injection-site erythema (ISE) from a phase III study. METHOD: Participants from the phase III, double-blind, randomized, 96 week equivalence study who completed the final visit received 50 mg YLB113 subcutaneously every 2 weeks...

OBJECTIVE: To compare the effectiveness and safety of original (Enbrel®) and biosimilar (Benepali®) etanercept in Biologic Disease-modifying Antirheumatic Drug (bDMARD)-naïve patients, measured by persistence rates over 36 months of follow-up. METHODS: A retrospective multicentre observational study using data collected prospectively from The Rheumatic Diseases Portuguese Registry (Reuma.pt) was performed, including patients with: age ≥ 18 years old; diagnosis of Rheumatoid Arthritis (RA), Psoriatic Arthritis (PsA) or Spondyloarthritis (SpA) (axial or peripheral) with active disease and biologic-naïve who initiated treatment with etanercept as the first line biological treatment after 2010...

Previously, N-acetyl-l-arginine (NALA) suppressed the aggregation of intravenous immunoglobulins (IVIG) more effectively and with a minimum decrease in transition temperature (Tm ) than arginine monohydrochloride. In this study, we performed a comparative study with etanercept (commercial product: Enbrel®), where 25 mM arginine monohydrochloride (arginine) was added to the prefilled syringe. The biophysical properties were investigated using differential scanning calorimetry (DSC), dynamic light scattering (DLS), size-exclusion chromatography (SEC), and flow-imaging microscopy (FI)...

OBJECTIVE: Since the expiry of the patents on originator anti-TNF agents in Europe, France has authorized the sale of biosimilars. The penetration rate of anti-TNF agents and their biosimilars, and the cost savings driven by the introduction of biosimilars appears to vary widely. This study aimed to describe the market share of anti-TNFs and their biosimilars, and the cost savings generated by the introduction of biosimilars in French hospitals 5 years ago. METHODS: The pharmaceutical component of the French national uniform hospital discharge data set database (PMSI) was used to study sales of infliximab, etanercept and adalimumab originators and biosimilars, and to estimate cost savings generated by the introduction of biosimilars onto the market, using the historical tariffs of the originators...
