Zusammenfassung: | This study aimed to compare the pharmacokinetics, safety, and immunogenicity of the prefilled syringe (PFS) with lyophilized (LYO) recombinant human tumor necrosis factor‐α receptor II:lgG Fc fusion protein (rhTNFR:Fc) in healthy Chinese male subjects. A single‐center, randomized, open‐label, 2‐period, crossover study was performed in healthy Chinese male subjects. Subjects were randomly assigned into 2 sequences and received a subcutaneous injection of 25 mg rhTNFR:Fc PFS or rhTNFR:Fc LYO (Anbainuo), with a 35‐day washout between the 2 periods. Blood samples were collected at specified time intervals, and then serum concentrations of rhTNFR:Fc were analyzed by enzyme‐linked immunosorbent assay. The maximum serum concentration, area under the concentration‐time curve (AUC) from time 0 to the last quantifiable concentration, and AUC from time 0 to infinity were all calculated and evaluated. Meanwhile, safety and immunogenicity were also assessed. A total of 82 subjects completed the study, and six subjects withdrew for various reasons. The 90%CIs for geometric mean ratios of maximum serum concentration, AUC from time 0 to the last quantifiable concentration, and AUC from time 0 to infinity were all within the equivalence range of 80% to 125%. Safety was comparable between the 2 formulations with low immunogenicity. rhTNFR:Fc PFS exhibited similar pharmacokinetic and safety profiles of rhTNFR:Fc LYO (Anbainuo) in healthy Chinese male subjects. |
