Comparative pharmacokinetics of an adalimumab biosimilar SB5 administered via autoinjector or prefilled syringe in healthy subjects.

ABSTRACT: Purpose:The objective of this study was to demonstrate comparable pharmacokinetic (PK), safety, and tolerability parameters of the adalimumab biosimilar SB5 administered via autoinjector (AI) pen or prefilled syringe (PFS). Patients and methods:In this phase 1, randomized, open-label, single-dose, parallel-group study, healthy subjects aged 18-55 years were randomized 1:1 to a single dose of 40 mg SB5 delivered subcutaneously via AI or PFS. PK parameters, safety, and tolerability were assessed for 57 days post-dose. The primary endpoint was area under the curve (AUC) of the concentration-time curve from zero to infinity (AUCinf) and from zero to last quantifiable concentration (AUClast) and maximum serum concentration (Cmax). Equivalence was determined using predefined margins of 0.80-1.25 for the 90% CI for the ratio of SB5 AI to SB5 PFS. Results:Ninety-five subjects were randomized to each group. Mean serum concentration-time profiles were superimposable between groups. Mean values for AUCinf, AUClast, and Cmax were similar between the SB5 AI and SB5 PFS groups. For the primary endpoints, the 90% CIs for the ratio of geometric least squares means for SB5 AI to SB5 PFS ranged between 0.9503 and 1.2240, which were all within the equivalence margin of 0.80-1.25. Incidence of treatment-emergent adverse events and injection site reactions was similar between groups. Conclusion:In healthy subjects receiving a single dose of SB5 via AI or PFS, PK parameters and corresponding 90% CIs were within the predefined margins, showing bioequivalence between the two delivery methods. Safety and tolerability assessments were also similar between groups. ClinicalTrialsgov identifier:NCT02326233. EudraCT number:2014-005178-12.

Project description:IntroductionThe aim of the study was to demonstrate the bioequivalence, and compare the safety and tolerability of MSB11022, a proposed biosimilar of adalimumab, when delivered by either an autoinjector (AI) or a pre-filled syringe (PFS).MethodsIn this pharmacokinetic (PK), parallel group, open-label study, 216 healthy volunteers were randomised 1:1 to receive a single subcutaneous injection of a 40 mg/0.8 mL dose of MSB11022 administered via AI or PFS. Coprimary PK endpoints were maximum observed concentration (Cmax), area under the concentration-time curve (AUC) from time 0 to the last quantifiable concentration (AUC0-t), and AUC from time 0 extrapolated to infinity (AUC0-inf). PK equivalence between the AI and PFS administration methods was declared if the 90% confidence intervals (CIs) for the ratio of geometric least square means was entirely contained within the 80-125% equivalence margin for all coprimary endpoints. Safety and tolerability were also evaluated.ResultsThe 90% CI for the three coprimary PK endpoints (Cmax, AUC0-t and AUC0-inf) were entirely contained within the predefined equivalence margins of 80-125%. Mean serum concentration-time profiles were similar following injection via AI or PFS. Treatment-emergent adverse events (TEAEs) were comparable across both treatment groups. Study device-related TEAEs were reported by 11.3% and 13.1% of subjects in the AI and PFS treatment groups, respectively. Study drug-related TEAEs were reported by 28.3% and 34.6% of subjects in the AI and PFS treatment groups, respectively. Few subjects experienced injection-site reactions, mainly pain and erythema, regardless of the administration method.ConclusionDelivery of MSB11022 via an AI is bioequivalent to delivery via a PFS. The safety and tolerability profile of MSB11022 was comparable across administration methods. The development of an AI for MSB11022 provides a choice of self-injection devices available to patients, potentially improving treatment compliance.Trial registrationClinicalTrials.gov trial identifier: NCT04018599.

Project description:IntroductionPegfilgrastim-cbqv (UDENYCA®; Coherus BioSciences, Redwood City, CA, USA) is a pegfilgrastim (Neulasta®; Amgen, Thousand Oaks, CA, USA) biosimilar approved for administration by prefilled syringe (PFS). The recently approved pegfilgrastim-cbqv prefilled autoinjector (AI) was developed as another method of self-administration and to aid in-office use, providing flexibility in drug delivery. The objectives of the study were to assess the pharmacokinetics (PK) and pharmacodynamics (PD) to determine bioequivalence of the prefilled AI and the PFS for administration of pegfilgrastim-cbqv and to assess the safety profile of the prefilled AI.MethodsDuring this open-label, two-period crossover study, healthy adult males (N = 155) were randomly assigned (1:1 ratio) to receive a subcutaneous injection of pegfilgrastim-cbqv using a prefilled AI (n = 76) or a PFS (n = 79) in period 1. During period 2, participants received an injection using the other method. Primary PK and secondary PD parameters were calculated to assess the bioequivalence of the treatment as administered by the two delivery methods. Safety and immunogenicity were also assessed.ResultsThe 90% CIs of the geometric mean ratios for the PK and PD parameters were within the required range (80-125%), demonstrating bioequivalence between the pegfilgrastim-cbqv prefilled AI and PFS. Treatment-emergent adverse events (TEAEs) were reported by 75% and 74.1% of participants in the prefilled AI and PFS groups, respectively. The most common TEAEs in both treatment groups were myalgia, bone pain, and headache. AI-device-related TEAEs were injection site pain (1.4%) and injection site bruising (0.7%). The incidence of antidrug antibodies and neutralizing antibodies was low and was similar in both treatment sequences.ConclusionsThe bioequivalence of pegfilgrastim-cbqv administered using a prefilled AI and a PFS was established. The safety, including immunogenicity profiles, of pegfilgrastim-cbqv administered using the prefilled AI and the PFS were similar, with no new safety findings.

Project description:IntroductionSB5 is an approved biosimilar of adalimumab, a monoclonal anti-tumor necrosis factor (anti-TNF) antibody. This study compared pharmacokinetics (PK), safety, tolerability, and immunogenicity between a new high-concentration, low-volume, and citrate-free formulation (40 mg/0.4 ml, SB5-HC) and the current low-concentration formulation with higher volume (40 mg/0.8 ml, SB5-LC) to evaluate the bioequivalence of the two formulations.MethodsThis study was a randomized, single-blind, two-arm, parallel-group, single-dose study in healthy male subjects. Subjects were randomized to receive either SB5-HC or SB5-LC via subcutaneous injection using a pre-filled syringe. Primary endpoints were the area under the curve of the concentration-time curve from zero to infinity (AUCinf) and maximum serum concentration (Cmax). Bioequivalence was achieved if the 90% confidence intervals (CIs) for the ratios of the geometric least squares mean (LSMean) of primary endpoints were within the pre-defined bioequivalence margins of 0.80-1.25. Secondary endpoints included safety, tolerability, and immunogenicity.ResultsSubjects (n = 188) were randomized to SB5-HC (n = 94) or SB5-LC (n = 94). Baseline characteristics were comparable between the two treatment groups. The mean values for AUCinf and Cmax were similar between the SB5-HC and SB5-LC groups. For the primary endpoints, the geometric LSMean ratios (90% CI) for AUCinf and Cmax were 0.920 (0.8262-1.0239) and 0.984 (0.9126-1.0604), respectively, placing the corresponding 90% CIs well within the pre-defined bioequivalence margin of 0.80-1.25. All treatment-emergent adverse events (TEAEs) were considered mild to moderate and were reported for 44.7% and 51.1% of subjects in the SB5-HC and SB5-LC groups, respectively. Immunogenicity assessed by frequency of occurrence of anti-drug antibodies (ADAs) and neutralizing antibodies (NAbs) was comparable between groups.ConclusionsThis bridging study demonstrated PK equivalence and comparable safety and tolerability of subcutaneous injection of SB5 via SB5-HC or SB5-LC.ClinicaltrialsGOV IDENTIFIER: https://clinicaltrials.gov/ct2/show/NCT04514796 .
