Physicochemical and functional characterization of MYL-1501D, a proposed biosimilar to insulin glargine.

ABSTRACT: Insulin glargine is a long-acting analogue of human insulin that has been used to manage hyperglycemia in patients with diabetes mellitus (DM) for nearly 20 years. Insulin glargine has a relatively constant concentration-time profile that mimics basal levels of insulin and allows for once-daily administration. MYL-1501D is a biosimilar insulin glargine designed to offer greater access of insulin glargine to patients, with comparable efficacy and safety to the marketed reference product. We conducted a comprehensive panel of studies based on a formal analysis of critical quality attributes to characterize the structural and functional properties of MYL-1501D and reference insulin glargine products available in the United States and European Union. MYL-1501D was comprehensively shown to have high similarity to the reference products in terms of protein structure, metabolic activity (both in vitro cell-based assays and in vivo rabbit bioassays), and in vitro cell-based assays for mitogenic activity. The structural analyses demonstrated that the primary protein sequence was identical, and secondary and tertiary structures are similar between the proposed biosimilar and the reference products. Insulin receptor binding affinity and phosphorylation studies also established analytical similarity. MYL-1501D demonstrated high similarity in different metabolic assays of glucose uptake, adipogenesis activity, and inhibition of stimulated lipolysis. Rabbit bioassay studies showed MYL-1501D and EU-approved insulin glargine are highly similar to US-licensed insulin glargine. These product quality studies show high similarity between MYL-1501D and licensed or approved insulin glargine products and suggest the potential of MYL-1501D as an alternative cost-effective treatment option for patients and clinicians.

Project description:BackgroundRegulatory approval for a biosimilar product is provided on the basis of its comparability to an originator product. A thorough physicochemical and functional comparability exercise is a key element in demonstrating biosimilarity. Here we report the characterization of a proposed biosimilar rituximab (GP2013) and originator rituximab.ObjectiveTo compare GP2013 with originator rituximab using an extensive array of routine analytical and extended characterization methods.MethodsPrimary and higher order protein structures were analyzed using a variety of methods that included high-performance liquid chromatography electrospray ionization mass spectrometry (HPLC-ESI-MS), peptide mapping with UV and MS detection, circular dichroism (CD), Fourier transform infrared (FTIR) spectroscopy, hydrogen deuterium exchange (HDX) MS, 1D (1)H nuclear magnetic resonance (NMR) spectroscopy, X-ray crystallography and differential scanning calorimetry (DSC). Charge and amino acid modifications were assessed using cation exchange chromatography (CEX) and peptide mapping using reversed-phase (RP) HPLC. Boronate affinity chromatography was used to determine the relative amount of glycation. Glycans were identified and quantified after 2-aminobenzamide (2-AB) labeling and separation using normal phase HPLC with fluorescence and MS detection, respectively. Glycan site occupancy was determined using reducing capillary electrophoresis with sodium dodecyl sulfate (CE-SDS). Size heterogeneity was determined using reducing and non-reducing CE-SDS, size exclusion chromatography (SEC) and asymmetric flow field flow fractionation (AF4). Biological characterization included a series of bioassays (in vitro target binding, antibody-dependent cell-mediated cytotoxicity [ADCC], complement-dependent cytotoxicity [CDC] and apoptosis) and surface plasmon resonance (SPR) Fc receptor binding assays.ResultsIntact mass analysis of GP2013 and the heavy and light chains using RP HPLC-ESI-MS revealed the expected molecular mass of rituximab. The amino acid sequence was shown to be identical between GP2013 and the originator rituximab. Further sequence confirmation using RP-HPLC-UV/MS peptide mapping showed non-distinguishable chromatograms for Lys-C digested GP2013 and originator rituximab. The higher order structure of GP2013 was shown to be indistinguishable from originator rituximab using a large panel of redundant and orthogonal methods. GP2013 and originator rituximab were comparable with regard to charge variants, specific amino acid modifications and the glycan pattern. GP2013 was also shown to have similar purity, aggregate and particle levels when compared with the originator. Functionally, and by using a comprehensive set of bioassays and binding assays covering a broad range of rituximab's functional activities, GP2013 could not be distinguished from originator rituximab.ConclusionGP2013 was shown to be physicochemically highly similar to originator rituximab at the level of primary and higher order structure, post-translational modifications and size variants. An extensive functional characterization package indicated that GP2013 has the same biological properties as originator rituximab.

Project description:PurposeBevacizumab is a recombinant humanized monoclonal antibody that inhibits vascular endothelial growth factor-specific angiogenesis in some cancers. MYL-1402O is a proposed bevacizumab biosimilar.MethodsThe primary objective of this single-center, randomized, double-blind, three-arm, parallel-group, phase 1 study in healthy male volunteers was to evaluate bioequivalence of MYL-1402O to EU and US-reference bevacizumab, and EU-reference bevacizumab to US-reference bevacizumab. The primary pharmacokinetic parameter was area under the serum concentration-time curve from 0 extrapolated to infinity (AUC0-∞). Pharmacokinetic parameters were analyzed using general linear models of analysis of variance. Secondary endpoints included safety and tolerability.ResultsOf 111 enrolled subjects, 110 were included in the pharmacokinetic analysis (MYL-1402O, n = 37; EU-reference bevacizumab, n = 36; US-reference bevacizumab, n = 37). Bioequivalence was demonstrated between MYL-1402O and EU-reference bevacizumab, MYL-1402O and US-reference bevacizumab, and between EU- and US-reference bevacizumab where least squares mean ratios of AUC0-∞ were close to 1, and 90% CIs were within the equivalence range (0.80-1.25). Secondary pharmacokinetic parameters (AUC from 0 to time of last quantifiable concentration [AUC0-t], peak serum concentration [Cmax], time to Cmax, elimination rate constant, and elimination half-life) were also comparable, with 90% CIs for ratios of AUC0-t and Cmax within 80-125%. Treatment-emergent adverse events were similar across all three treatment groups and were consistent with clinical data for bevacizumab.ConclusionMYL-1402O was well tolerated and demonstrated pharmacokinetic and safety profiles similar to EU-reference bevacizumab and US-reference bevacizumab in healthy male volunteers. No new significant safety issues emerged (ClinicalTrials.gov, NCT02469987; ClinicalTrialsRegister.eu EudraCT, 2014-005621-12; June 12, 2015).

Project description:PurposeThis phase III study compared the efficacy and safety of proposed biosimilar MYL-1402O with reference bevacizumab (BEV), as first-line treatment for patients with stage IV non-squamous non-small-cell lung cancer.Patients and methodsPatients were randomly assigned (1:1) to receive MYL-1402O or bevacizumab with carboplatin-paclitaxel up to 18 weeks (6 cycles), followed by up to 24 weeks (8 cycles) of bevacizumab monotherapy. The primary objective was comparison of overall response rate (ORR), based on independently reviewed best tumor responses as assessed during the first 18 weeks. ORR was analyzed per US Food and Drug Administration (ratio of ORR) and European Medicines Agency (difference in ORRs) requirements for equivalence evaluation. Secondary end points included progression-free survival, disease control rate, duration of response, overall survival, safety, and immunogenicity over a period of 42 weeks, and pharmacokinetics (up to 18 weeks).ResultsA total of 671 patients were included in the intent-to-treat population. The ratio of ORR was 0.96 [confidence interval (CI) 0.83, 1.12] and the difference in ORR was -1.6 (CI -9.0, 5.9) between treatment arms; CIs were within the predefined equivalence margins. Overall, the incidence of treatment-emergent adverse events and serious adverse events was comparable. Treatment-emergent anti-drug antibody (ADA) positivity was transient, with no notable differences between treatment arms (6.5% versus 4.8% ADA positivity rate in MYL-1402O versus BEV, respectively). The incidence of neutralizing antibody post-baseline was lower in the MYL-1402O arm (0.6%) compared to the bevacizumab arm (2.5%).ConclusionsMYL-1402O is therapeutically equivalent to bevacizumab, based on the ORR analyses, with comparable secondary endpoints.Trial registry informationEU Clinical Trials Register, Registration # EudraCT no. 2015-005141-32https://www.clinicaltrialsregister.eu/ctr-search/search?query=2015-005141-32.Plain language summaryPrevious studies established bioequivalence of the proposed bevacizumab biosimilar MYL-1402O to reference bevacizumab. In this randomized, double-blind, phase III trial, MYL-1402O (n = 337) demonstrated comparable efficacy to bevacizumab (n = 334) in treating advanced non-squamous non-small-cell lung cancer per Food and Drug Administration and European Medicines Agency requirements for equivalence; the ratio of objective response rate (ORR) was 0.96 [90% confidence interval (CI) 0.83, 1.12] and the difference in ORR (MYL-1402O:bevacizumab) was -1.6 (95% CI -9.0, 5.9). Median progression-free survival at 42 weeks was comparable: 7.6 (7.0, 9.5) with MYL-1402O versus 9.0 (7.2, 9.7) months (p = 0.0906) with bevacizumab, by independent review. Treatment-emergent adverse events leading to death (2.4% vs 1.5%), serious adverse events (17.6% vs 16.7%), and antidrug antibodies (6.5% vs 4.8%), were comparable in the MYL-1402O vs bevacizumab arms, respectively. The incidence of neutralizing antibody post-baseline was lower with MYL-1402O (0.6%) than with bevacizumab (2.5%). These findings confirm therapeutic equivalence of MYL-1402O to bevacizumab, providing opportunities for improving access to bevacizumab.
