Lee HA, Kim S, Seo H, Kim S. A phase I, randomized, double-blind, single-dose pharmacokinetic study to evaluate the biosimilarity of SB16 (proposed denosumab biosimilar) with reference denosumab in healthy male subjects. Expert Opin Investig Drugs 2023; 32:959-966. [PMID: 37870163 DOI: 10.1080/13543784.2023.2273510] [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: 09/05/2023] [Accepted: 10/17/2023] [Indexed: 10/24/2023]
Abstract
BACKGROUND SB16 is a biosimilar to reference denosumab (DEN). This study assessed pharmacokinetic (PK) equivalence and evaluated pharmacodynamic (PD), safety, tolerability, and immunogenicity between SB16, European Union-sourced DEN (EU-DEN), and United States-sourced DEN (US-DEN). RESEARCH DESIGN AND METHODS In this double-blind, parallel group, and single-dose study, healthy male subjects were randomized 1:1:1 to receive a single 60 mg dose of either SB16, EU-DEN, or US-DEN subcutaneously. PK, PD, safety, and immunogenicity were evaluated for 197 days. Primary PK endpoints were area under the concentration-time curve (AUC) from time zero to infinity, AUC from time zero to the last quantifiable concentration, and maximum serum concentration (Cmax). Equivalence was determined if 90% confidence intervals (CIs) for the ratio of geometric least squares means (LS Means) were within the equivalence margin of 0.80 to 1.25. RESULTS A total of 168 subjects (56 per treatment group) were randomized. All of the corresponding 90% CI of geometric LS Means ratio of primary PK parameters were within the pre-defined equivalence margin. PD, safety, and immunogenicity profiles were also comparable between the treatment groups. CONCLUSION This study demonstrated PK bioequivalence between SB16, EU-DEN, and US-DEN in healthy male subjects. TRIALREGISTRATION CT.gov identifier: NCT04621318.

Infliximab Efficacy May Be Linked to Full TNF-α Blockade in Peripheral Compartment-A Double Central-Peripheral Target-Mediated Drug Disposition (TMDD) Model. Pharmaceutics 2021; 13:pharmaceutics13111821.

Abstract
Infliximab is an anti-TNF-α monoclonal antibody approved in chronic inflammatory bowel diseases (IBD). This study aimed at providing an in-depth description of infliximab target-mediated pharmacokinetics in 133 IBD patients treated with 5 mg/kg infliximab at weeks 0, 2, 14, and 22. A two-compartment model with double target-mediated drug disposition (TMDD) in both central and peripheral compartments was developed, using a rich database of 26 ankylosing spondylitis patients as a reference for linear elimination kinetics. Population approach and quasi-steady-state (QSS) approximation were used. Concentration-time data were satisfactorily described using the double-TMDD model. Target-mediated parameters of central and peripheral compartments were respectively baseline TNF concentrations (RC0 = 3.3 nM and RP0 = 0.46 nM), steady-stated dissociation rates (KCSS = 15.4 nM and KPSS = 0.49 nM), and first-order elimination rates of complexes (kCint = 0.17 day−1 and kPint = 0.0079 day−1). This model showed slower turnover of targets and infliximab-TNF complex elimination rate in peripheral compartment than in central compartment. This study allowed a better understanding of the multi-scale target-mediated pharmacokinetics of infliximab. This model could be useful to improve model-based therapeutic drug monitoring of infliximab in IBD patients.

Infliximab Treatment Does Not Lead to Full TNF-α Inhibition: A Target-Mediated Drug Disposition Model. Clin Pharmacokinet 2021; 61:143-154. [PMID: 34351609 DOI: 10.1007/s40262-021-01057-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 07/06/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND AND OBJECTIVE Infliximab, an anti-tumour necrosis factor (TNF)-α monoclonal antibody, has been approved in chronic inflammatory disease, including rheumatoid arthritis, Crohn's disease and ankylosing spondylitis. This study aimed to investigate and characterise target-mediated drug disposition of infliximab and antigen mass turnover during infliximab treatment. METHODS In this retrospective cohort of 186 patients treated with infliximab for rheumatoid arthritis, Crohn's disease or ankylosing spondylitis, trough infliximab concentrations were determined from samples collected between weeks 0 and 22 after treatment initiation. Target-mediated pharmacokinetics of infliximab was described using target-mediated drug disposition modelling. Target-mediated elimination parameters were determined for rheumatoid arthritis and Crohn's disease, assuming ankylosing spondylitis with no target-mediated elimination. RESULTS The quasi-equilibrium approximation of a target-mediated drug disposition model allowed a satisfactory description of infliximab concentration-time data. Estimated baseline TNF-α amounts were similar in Crohn's disease and rheumatoid arthritis (R0 = 0.39 vs 0.46 nM, respectively), but infliximab-TNF complex elimination was slower in Crohn's disease than in rheumatoid arthritis (kint = 0.024 vs 0.061 day-1, respectively). Terminal elimination half-lives were 13.5, 21.5 and 16.5 days for rheumatoid arthritis, Crohn's disease and ankylosing spondylitis, respectively. Estimated amounts of free target were close to baseline values before the next infusion suggesting that TNF-α inhibition may not be sustained over the entire dose interval. CONCLUSIONS The present study is the first to quantify the influence of target antigen dynamics on infliximab pharmacokinetics. Target-mediated elimination of infliximab may be complex, involving a multi-scale turnover of TNF-α, especially in patients with Crohn's disease. Additional clinical studies are warranted to further evaluate and fine-tune dosing approaches to ensure sustained TNF-α inhibition.
