ABSTRACTBackgroundAVT02 is an adalimumab biosimilar, with bioequivalence previously established along with clinical similarity. This study assessed the pharmacokinetic (PK) similarity of a single dose of 100 mg/mL AVT02 administered via prefilled syringe (PFS) or autoinjector (AI).Research design and methodsIn this open-label, 2-arm, parallel-group study, healthy adults were randomized 1:1 to receive one 40 mg (100 mg/mL) dose of AVT02 subcutaneously via PFS (N = 102) or AI (N = 105). Primary PK parameters (Cmax, AUC0-tand AUC0-inf) were evaluated up to Day 64 of the study. Secondary PK parameters, safety, tolerability and immunogenicity were also assessed.ResultsThe 90% CIs for the ratio of geometric least squares means were contained within the pre-specified 80–125% equivalence margins for the primary PK parameters, demonstrating bioequivalence of AVT02 when administered by PFS or AI. The incidence of treatment-emergent adverse events was comparable between the two groups, with a low frequency of injection site reactions observed. Immunogenicity profiles were also similar between the two groups.ConclusionBioequivalence was demonstrated for a single dose of AVT02 administered via PFS or AI. These results will help to increase availability of devices for patients, enabling treatment choice and flexibility.
