PG - 1166-1173 LID - 10.1002/cpdd.939 [doi] AB - This open-label, single-dose, randomized, parallel-group, 2-arm phase 1 bioequivalence (BE) study assessed the pharmacokinetics (PK), safety, and tolerability of PF-06410293 (ADL-PF), an adalimumab (ADL) biosimilar, following administration by prefilled pen (PFP) or prefilled syringe (PFS). A total of 164 healthy adult subjects were randomized (1:1) to receive ADL-PF (40 mg subcutaneously) in the lower abdomen or upper anterior thigh by PFS or PFP; 163 subjects were included in the primary PK analysis. The concentration-time profiles of the ADL-PF PFS and PFP treatment arms were similar. The 90% confidence intervals for the test/reference ratios of the primary end points (area under the serum concentration-time profile from time 0 to 2 weeks after dosing and maximum observed serum concentration) fell within the 80.00%-125.00% prespecified margin for BE. Comparable numbers of subjects experienced adverse events (AEs) between treatment groups, and injection-site pain was similar at all times and for the 2 injection-site locations. This study demonstrated the BE of ADL-PF following subcutaneous administration using either a PFS or PFP device. ADL-PF by PFS or PFP injection was well tolerated, with the distribution of AEs, including injection-site reactions, being similar between treatment arms. CI - (c) 2021 Pfizer Inc.
