A Phase I Clinical Study Comparing the Tolerance, Immunogenicity, and Pharmacokinetics of Proposed Biosimilar BAT1806 and Reference Tocilizumab in Healthy Chinese Men.

ABSTRACT: Objective: The study aimed to explore the bioequivalence of a proposed biosimilar BAT1806 to its reference products marketed in the EU and US (RoActemra-EU and Actemra-US) among healthy Chinese men. The tolerance, immunogenicity, and pharmacokinetics (PK) of the three drugs were also investigated. Methods: In this randomized, double-blind, single-dose, three-arm, parallel study, a single-dose of 4 mg/kg of the reference products, or the biosimilar was administered to the participants. The participants were followed up for 57 days, and PK, immunogenicity, and tolerance evaluations were completed during this period. Results: The PK parameters were similar in all three groups: BAT1806 (n = 45), RoActemra-EU (n = 42), and Actemra-US (n = 42). The 90% confidence intervals (CIs) for the ratios of C _max , AUC_0-t and AUC_0-? were 86.90-104.41% for BAT1806 vs. RoActemra-EU, 91.70-106.15% for BAT1806 vs Actemra-US, and 90.04-105.53% for Actemra-US vs RoActemra-EU. For all comparisons, the 90% CIs for the C _max , AUC_0-t , and AUC_0-? were within the predefined bioequivalence limit of 80.00-125.00%. The intersubject variability ranged from 14.5% to 21.5%, which was considerably low. Among the participants, 19 (42.2%), 10 (23.8%), and 12 (28.6%) from the BAT1806, RoActemra-EU, and Actemra-US groups were, respectively, found to be positive for anti-drug antibodies, while 14 (31.1%), nine (21.4%), and 12 (28.6%) were positive for neutralizing antibodies. Nevertheless, these antibodies did not affect the drug concentrations, and the outcomes in the bioequivalence tests were similar after sensitivity analysis. Treatment-related and treatment-emergent adverse events (TEAEs) were recorded in 27, 34, and 32 participants in the BAT1806, RoActemra-EU, and Actemra-US groups, respectively. The most common treatment-related adverse events observed were a decrease in neutrophil, and white blood cell counts. Conclusion: The PK characteristics of BAT1806 were similar to those of the reference products, RoActemra-EU and Actemra-US. Both BAT1806 and the reference products exhibited low intersubject variability and similar safety profiles.

Project description:AimsThis study aimed to demonstrate that the pharmacokinetic (PK) and pharmacodynamic (PD) profile of Sandoz proposed biosimilar pegfilgrastim (LA-EP2006) matches reference pegfilgrastim (Neulasta® ) in healthy subjects. Safety and immunogenicity were also assessed.MethodsThe phase I, randomized, double-blind, two-period crossover study consisted of two treatment periods separated by an 8-week washout period. Healthy subjects aged 18-45 were randomized to either proposed biosimilar/reference pegfilgrastim or reference pegfilgrastim/proposed biosimilar. Proposed biosimilar and reference pegfilgrastim were administered on Day 1 of each treatment period (single 6 mg subcutaneous injection). Blood samples for PK/PD analysis were taken predose and ≤336 h postdose. PK/PD similarity was claimed if 90% (PK) and 95% (PD) confidence intervals (CI) for geometric mean ratios of the area under the serum concentration-time curve (AUC) from time of dosing and extrapolated to infinity (AUC0-inf ), or to the last measurable concentration (AUC0-last ), maximum observed serum concentration (Cmax ), absolute neutrophil count (ANC) area under the effect curve from the time of dosing to the last measurable concentration (AUEC0-last ) and ANC maximum effect attributable to the therapy under investigation (Emax ) were completely contained within the predefined margin (0.8 to 1.25).ResultsOverall, 169 subjects completed the study. PK/PD similarity was demonstrated; 90% CIs of geometric mean ratio of proposed biosimilar/reference for PK: AUC0-inf (1.0559-1.2244), AUC0-last (1.0607-1.2328), Cmax (1.0312-1.1909) and 95% CIs for PD (ANC): AUEC0-last (0.9948-1.0366), Emax (0.9737-1.0169) were completely contained within predefined margin of 0.8 to 1.25. Both biologics had similar safety profiles, were well tolerated and had low incidence of anti-drug antibodies. No neutralizing or clinically relevant antibodies were detected.ConclusionsPK/PD similarity of Sandoz proposed biosimilar pegfilgrastim and reference pegfilgrastim was confirmed. No clinically meaningful differences in safety, tolerability and immunogenicity were observed in healthy subjects.

Project description:IntroductionPF-06881894 is a proposed biosimilar to pegfilgrastim (Neulasta®). This study evaluated the pharmacodynamic/pharmacokinetic (PD/PK) equivalence, immunogenicity, and safety of PF-06881894 vs pegfilgrastim reference products (US- and EU-Neulasta®) in healthy volunteers.MethodsA phase 1, open-label, randomized, crossover study was conducted to assess the pharmacologic equivalence and safety of a single 6-mg dose of PF-06881894, pegfilgrastim-US, and pegfilgrastim-EU. The primary PD endpoints were area under the effect-versus-time curve for absolute neutrophil count (ANC) from dose administration to 288 h postdose, and maximum observed ANC value among subjects confirmed negative for anti-pegfilgrastim antibodies. Primary PK variables included area under the serum pegfilgrastim-versus-time curve from the time of dose administration to time infinity and maximum observed serum pegfilgrastim concentration. A second phase 1, open-label, randomized (1:1), parallel-group, non-inferiority study was conducted to assess the immunogenicity and safety of multiple 6-mg doses of PF-06881894 versus pegfilgrastim-US. The primary endpoint for the immunogenicity study was the proportion of subjects with both negative baseline and confirmed positive postdose anti-pegfilgrastim antibodies at any time during the study.ResultsAcross the single- and multiple-dose studies (N = 153 and N = 420 treated subjects, respectively), demographics for age (18-65 years), male gender (n = 264/573), and white race (n = 423/573) were similar. Three-way PD/PK equivalence of PF-06881894, pegfilgrastim-US, and pegfilgrastim-EU was demonstrated with the primary PD endpoints and primary PK variables being completely contained within the predefined 90% confidence interval acceptance limits (80-125%). The non-inferiority of PF-06881894 versus pegfilgrastim-US in terms of immunogenicity was established according to the prespecified non-inferiority margin (≤10%). Overall, there were no clinically meaningful differences in safety profiles among or between study groups.ConclusionsSingle-dose PF-06881894 demonstrated PD/PK equivalence and comparable safety with US- and EU-pegfilgrastim reference products. Multiple-dose PF-06881894 demonstrated immunogenicity non-inferiority to pegfilgrastim-US with comparable safety. Both studies contributed to the totality of evidence supporting biosimilarity.Trial registrationClinicalTrials.gov identifiers: NCT02629289; NCT03273842 (C1221005).

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:Background:Following the functional and physicochemical characterization of a proposed biosimilar, comparative clinical studies help to confirm biosimilarity by demonstrating similar safety and efficacy to the reference product in a sensitive patient population. Patients and methods:LA-EP2006 is a proposed biosimilar that has been developed for pegfilgrastim, a long-acting form of granulocyte colony-stimulating factor for the prevention of neutropenia. The current analysis reports data pooled from two independent, multinational, prospective, randomized, controlled, double-blind phase III studies of similar design comparing the safety and efficacy of reference pegfilgrastim with LA-EP2006 in patients with breast cancer receiving myelotoxic (neo)adjuvant TAC (docetaxel, doxorubicin, and cyclophosphamide) chemotherapy and requiring granulocyte colony-stimulating factor. Results:A total of 624 patients were randomized in the PROTECT-1 and PROTECT-2 studies (NCT01735175; NCT01516736) (LA-EP2006: n?=?314; reference: n?=?310). Baseline characteristics of patients were well balanced across treatment groups. The primary end point, mean duration of severe neutropenia in the first chemotherapy cycle was similar in both the LA-EP2006 and reference groups (1.05?±?1.055 days versus 1.01?±?0.958 days), with a treatment difference of?-?0.04 days [95% confidence interval (CI): -0.19 to 0.11] that met the equivalence criteria (the 95% CI were within the defined margin of?±1?day). Secondary end points, such as the nadir of absolute neutrophil count and the incidence of febrile neutropenia, were also similar between LA-EP2006 and reference pegfilgrastim. The safety and tolerability profile of LA-EP2006 was similar to that observed with reference pegfilgrastim, and there were no reports of neutralizing antibodies. Conclusions:This pooled analysis confirms, as a part of totality of evidence approach, that the proposed biosimilar pegfilgrastim LA-EP2006 has a comparable efficacy and safety profile to reference pegfilgrastim in patients with breast cancer receiving TAC chemotherapy.
