Project description:BackgroundBiologics, regardless of whether they are biosimilars or reference products, are inherently variable due to their size, complexity, and the manufacturing process involved to produce them. Since a drift or evolution of quality attributes of a biologic may impact its clinical safety or efficacy, it is critical for the manufacturer to carefully control the manufacturing process and monitor the quality attributes of a biologic.ObjectiveThe aim of this study was to demonstrate that the quality profile of the SB5 drug product has been consistent over its production history from 2013 to 2022. SB5 is a biosimilar referencing adalimumab (Humira, trademark of AbbVie Biotechnology Ltd) and SB5 has been approved by 14 regulatory authorities including the European Commission in August 2017 (brand name Imraldi™) and the US Food and Drug Administration in July 2019 (brand name Hadlima™).MethodsA total of 93 SB5 drug product batches manufactured between 2013 and 2022 were analyzed for a series of release parameters to evaluate the consistency in their critical quality attributes including purity, charge variants, and functional activities (TNF-α binding activity and TNF-α neutralizing potency).ResultsThe purity, charge variants, and functional activities of all batches were consistent over time and within the stringent acceptance criteria defined by regulatory agencies to ensure the safety and efficacy of SB5.ConclusionThe data presented in this study provide evidence that the quality of SB5 has remained consistent and tightly controlled even through process changes such as manufacturing site transfers and change in formulation.

Project description:Recombinant human follicle-stimulating hormone (r-hFSH) is widely used in fertility treatment. Although biosimilar versions of r-hFSH (follitropin alfa) are currently on the market, given their structural complexity and manufacturing process, it is important to thoroughly evaluate them in comparison with the reference product. This evaluation should focus on how they differ (e.g., active component molecular characteristics, impurities and potency), as this could be associated with clinical outcome. This study compared the site-specific glycosylation profile and batch-to-batch variability of the in-vivo bioactivity of Bemfola, a biosimilar follitropin alfa, with its reference medicinal product GONAL-f. The focus of this analysis was the site-specific glycosylation at asparagine (Asn) 52 of the α-subunit of FSH, owing to the pivotal role of Asn52 glycosylation in FSH receptor (FSHR) activation/signalling. Overall, Bemfola had bulkier glycan structures and greater sialylation than GONAL-f. The nominal specific activity for both Bemfola and GONAL-f is 13,636 IU/mg. Taking into account both the determined potency and the nominal amount the average specific activity of Bemfola was 14,522 IU/mg (105.6% of the nominal value), which was greater than the average specific activity observed for GONAL-f (13,159 IU/mg; 97.3% of the nominal value; p = 0.0048), although this was within the range stated in the product label. A higher batch-to-batch variability was also observed for Bemfola versus GONAL-f (coefficient of variation: 8.3% vs 5.8%). A different glycan profile was observed at Asn52 in Bemfola compared with GONAL-f (a lower proportion of bi-antennary structures [~53% vs ~77%], and a higher proportion of tri-antennary [~41% vs ~23%] and tetra-antennary structures [~5% vs <1%]). These differences in the Asn52 glycan profile might potentially lead to differences in FSHR activation. This, together with the greater bioactivity and higher batch-to-batch variability of Bemfola, could partly explain the reported differences in clinical outcomes. The clinical relevance of the differences observed between GONAL-f and Bemfola should be further investigated.

Project description:PurposeQX003S is a biosimilar candidate for the reference tocilizumab, Actemra®. We investigated the tolerance, variability, and pharmacokinetics (PK) of QX003S biosimilar in healthy Chinese male subjects.DesignA randomised, double-blind, two-arm, parallel study was performed to examine the bioequivalence of QX003S (8 mg/kg) with that of Actemra® as a reference drug.ResultsQX003S (N = 40) and Actemra® (N = 40) groups exhibited similar PK properties. The inter-subject variability ranged from 14.95% to 18.78%. The 90% confidence intervals of the ratios for Cmax, AUC0-t andAUC0-∞ in both groups were within the range of 80-125%. After administration, the number of subjects who tested positive for anti-drug antibodies (ADA) in the QX003S group and Actemra® groups was 6 (14.3%) and 14 (34.1%), respectively. Adverse reactions occurred in 100% and 97.6% subjects in the QX003S and Actemra® groups, respectively. The most common adverse reactions were decrease in fibrinogen level and neutrophil and leukocyte counts.ConclusionThe PK characteristics and immunogenicity exhibited by QX003S were similar to that of the reference product, Actemra®. The safety profile was similar in the two treatment groups with mild-moderate adverse effects.Trial RegistrationThe trial is registered at Chinese Clinical Trial website (http://www.chinadrugtrials.org.cn/index.html#CTR20190002)Key pointsThis was the first clinical report of a new proposed tocilizumab biosimilar, QX003S.This phase-I randomized, controlled study compared pharmacokinetics, variability,immunogenicity, and safety of QX003S vs. the approved tocilizumab product (Actemra@).The results demonstrate bioequivalence between BAT1806 and the reference products (Actemra@), as well as comparable immunogenicity, safety and tolerability profiles.

Project description:ObjectiveWe compared the efficacy, safety, and immunogenicity of a biosimilar recombinant human follicle-stimulating hormone (Folitime®) with Gonal-f® in women undergoing ovarian stimulation for in-vitro fertilization.MethodsThis randomized (1:1), multicenter, assessor-blinded, non-inferiority, parallel-group, controlled study conducted at four infertility clinics in Argentina included infertile normogonadotropic women with ages below 39 years, with menstrual cycles of 25/35 days and a body mass index of 18-32 kg/m2 undergoing assisted reproductive technology therapy. During a 5-day fixed-dose phase, the women received 225 IU/day of Folitime® (n=49) or Gonal-f® (n=44), followed by a dose-adaptation phase up to a maximum of 450 IU/day. The non-inferiority margin for oocyte retrieval was estimated at -4 oocytes (one-sided test). Immunogenicity was investigated on days 9 and 84, following the start of treatment.ResultsThe mean number of oocytes retrieved was 12.6 (SD 7.4) in the Folitime® group and 13.4 (SD 6.9) in the Gonal-f® group (per protocol analysis, 95% confidence interval = -3.82; 2.33), within the non-inferiority margin. Pregnancy rate at week 10 was 24.4% among subjects treated with Folitime® and 19.5% for subjects treated with Gonal-f®. One serious adverse drug reaction-late mild ovarian hyper stimulation syndrome and deep venous thrombosis in the left deep jugular vein-occurred in a subject treated with Folitime®. None of the subjects developed antibodies against the study drugs. There were no unexpected safety findings.ConclusionsFolitime® is non-inferior to Gonal-f®, with no differences in the safety profile and has been approved as a biosimilar in Argentina.

Project description:AimThe purpose of this study was to evaluate the extended physicochemical and biological stability of Sandoz Rixathon®/Riximyo® (SDZ-RTX) after exposure to out-of-fridge (OOF) conditions.Materials and methodsThe impact of the short-term temperature excursion on stability parameters of SDZ-RTX was simulated by subsequently exposing the three batches of SDZ-RTX (100 and 500 mg) to OOF conditions, (I) 25 ± 2 °C/60 ± 5% relative humidity (RH) and (II) 30 ± 2 °C/65 ± 5% RH, for up to 21 days after more than the claimed 36-month shelf-life storage in long-term conditions (5 ± 3 °C). Analytical methods used included the cation exchange chromatography (CEX), size exclusion chromatography (SEC), and non-reducing capillary electrophoresis-sodium dodecyl sulfate (nrCE-SDS), as well as biological activity by complement-dependent cytotoxicity (CDC)-bioactivity as well as further methods, for example, related to identity and pharmacopoeia test methods.ResultsNo notable changes were observed across all batches with respect to identity (charge and primary structure), pharmaceutical tests (clarity, visible and subvisible particles analytics, container appearance, degree of coloration, pH, osmolality, extractable volume, and container closure integrity testing), protein content by UV and microbiological parameters (sterility and bacterial endotoxins) under both OOF conditions. Only minor changes were observed for parameters evaluated via SEC, CEX, and nrCE-SDS. For potency (CDC-bioactivity) only one of the batches showed a relevant change. Even for these stability-indicating test methods, all analyzed parameters complied with the shelf-life specifications.ConclusionSDZ-RTX is safe for use even under worst-case conditions, for example, after subjecting it for up to 21 days at OOF conditions (25 ± 2 °C/60 ± 5% RH or 30 ± 2 °C/65 ± 5% RH) after the batches had reached an age that was already beyond the claimed shelf-life.

Project description:FSH glycosylation varies in two functionally important aspects: microheterogeneity, resulting from oligosaccharide structure variation, and macroheterogeneity, arising from partial FSHβ subunit glycosylation. Although advances in mass spectrometry permit extensive characterization of FSH glycan populations, microheterogeneity remains difficult to illustrate, and comparisons between different studies are challenging because no standard format exists for rendering oligosaccharide structures. FSH microheterogeneity is illustrated using a consistent glycan diagram format to illustrate the large array of structures associated with one hormone. This is extended to commercially available recombinant FSH preparations, which exhibit greatly reduced microheterogeneity at three of four glycosylation sites. Macroheterogeneity is demonstrated by electrophoretic mobility shifts due to the absence of FSHβ glycans that can be assessed by Western blotting of immunopurified FSH. Initially, macroheterogeneity was hoped to matter more than microheterogeneity. However, it now appears that both forms of carbohydrate heterogeneity have to be taken into consideration. FSH glycosylation can reduce its apparent affinity for its cognate receptor by delaying initial interaction with the receptor and limiting access to all of the available binding sites. This is followed by impaired cellular signaling responses that may be related to reduced receptor occupancy or biased signaling. To resolve these alternatives, well-characterized FSH glycoform preparations are necessary.

Project description:IntroductionBI 695501 has shown similar efficacy, safety, and immunogenicity to the adalimumab reference product, Humira®. We present two phase 1 studies comparing the pharmacokinetics, safety, and immunogenicity of BI 695501 delivered via autoinjector (AI) vs. prefilled syringe (PFS).MethodsBoth trials were randomized, open-label, parallel-group studies undertaken in subjects aged ≥ 18-65 years. VOLTAIRE®-AI (NCT02606903) recruited healthy, Caucasian, male, non-athletic volunteers with BMI ≥ 18 to ≤ 30 kg/m2. VOLTAIRE®-TAI (NCT02899338) recruited healthy men and women with BMI > 17.5 to < 35 kg/m2. In both studies, a single dose of BI 695501 40 mg was administered via AI or PFS to the abdomen (VOLTAIRE®-AI) or thigh (VOLTAIRE®-TAI). The observation period was 43/57 days and the safety follow-up was 70 days. Co-primary endpoints were AUC0-1032 or AUC0-1368, Cmax, and AUC0-∞. Safety and immunogenicity were assessed.ResultsSubjects (VOLTAIRE®-AI: N = 71; VOLTAIRE®-TAI: N = 162) were randomized to AI (n = 35; n = 81) or PFS (n = 36; n = 81). Baseline characteristics were balanced between treatment groups in each study. Total exposure of BI 695501 was similar for both groups; adjusted geometric mean ratios for AUC0-∞, AUC0-1032, and Cmax were 106.17, 104.09, and 114.83%, respectively, for VOLTAIRE®-AI; 103.19, 101.71 (AUC0-1368), and 100.11% for VOLTAIRE®-TAI. In both studies, similar immunogenicity was observed between groups in terms of frequency of binding and neutralizing anti-drug antibody-positive subjects. Incidence of adverse events was similar for both groups.ConclusionsPharmacokinetics and immunogenicity of BI 695501 delivered via AI were similar to administration using a PFS, independent of injection site. No differences are expected between AI and PFS use in clinical practice.FundingBoehringer Ingelheim.

Project description:BackgroundBiosimilars must meet stringent regulatory requirements, both at the time of authorization and during their lifecycle. Yet it has been suggested that divergence in quality attributes over time may lead to clinically meaningful differences between two versions of a biologic. Therefore, this study investigated the batch-to-batch consistency across a range of parameters for released batches of the etanercept biosimilar (SB4) and infliximab biosimilar (SB2).MethodsSB4 (Benepali®) and SB2 (Flixabi®) were both developed by Samsung Bioepis and are manufactured in Europe by Biogen at their facility in Hillerød, Denmark. A total of 120 batches of SB4 and 25 batches of SB2 were assessed for consistency and compliance with specified release parameters, including purity, post-translational glycosylation (SB4 only), protein concentration, and biological activity.ResultsThe protein concentration, purity, tumor necrosis factor-α (TNF-α) binding, and TNF-α neutralization of all batches of SB4 and SB2 were within the strict specification limits set by regulatory agencies, as was the total sialic acid (TSA) content of all batches of SB4.ConclusionsQuality attributes of SB4 and SB2 batches showed little variation and were consistently within the rigorous specifications defined by regulatory agencies.

Project description:BackgroundComplications of bone metastases such as skeletal-related events lead to the impaired functional status and quality of life including death in patients with bone metastasis from solid tumors. Denosumab (XGEVA®) is indicated for the prevention of skeletal-related events in bone metastasis patients with solid tumors. The biosimilar product LY01011, a fully human anti-receptor activator of nuclear factor kappa-B ligand monoclonal antibody, was developed to be compared with the reference product denosumab.Material and methodsA randomized, double-blind, single-dose, parallel-controlled phase 1 study was conducted in healthy Chinese subjects. A total of 168 enrolled subjects were randomly assigned in a 1:1 ratio to receive a single 120 mg dose of LY01011 (n = 85) or denosumab (n = 83) subcutaneously. The primary pharmacokinetic (PK) parameters, including maximum plasma concentration (Cmax) and area under the concentration-time curve from time zero to last quantifiable concentration (AUC0→t), were collected and measured for evaluation. Other secondary PK parameters included AUC0- ∞, Tmax, CL/F, λz, t1/2, Vd/F, etc. Pharmacodynamics (PD), safety and immunogenicity profiles were also accounted for data analysis.ResultsThe geometric mean ratios (GMRs) of LY01011 and denosumab for the primary PK parameters such as Cmax and AUC0→t were 98.13% and 100.32%. The 90% confidence intervals (CIs) were all within the acceptance range of 80%-125%. The GMRs of the PD parameters including AUEC0→t and Emax were 98.71% and 99.80%, which fell within the pre-defined acceptance range of 80%-125%. The results also demonstrated PK similarity even if Cmax and AUC0→∞ had been used as primary endpoints. Safety profiles were tolerable and similar between groups. 4 (4.7%) and 2 (2.4%) subjects had experienced Grade 3 or above treatment-emergent adverse events (TEAEs) in LY01011 group and denosumab group. 3 subjects were reported to have serious adverse events (SAEs). None of the Grade 3 or above TEAEs and SAEs were related to the study drug, LY01011. No subject was tested anti-drug antibody (ADA) positive in both groups prior to the study drug administration. Following the study drug administration, only one subject in denosumab group was tested ADA positive, whereas no subject with ADA positive was reported in LY01011 group. No neutralizing antibody (Nab) was detected in either group throughout the study.ConclusionsThe study demonstrated PK and PD similarity of LY01011, a denosumab biosimilar, to denosumab in healthy Chinese subjects, with comparable safety and immunogenicity profiles.

Project description:Insulin glargine is a long-acting insulin analog, which plays an important role in the treatment of diabetes mellitus. Biosimilar products of insulin glargine can provide patients with additional safe, high-quality, and potentially cost-effective options for treating diabetes. This article presents a randomized, double-blind, single-dose, two-treatment, four-period, replicate crossover, euglycemic clamp study which was designed to evaluate the PK and PD similarity between the recombinant insulin glargine developed by Wanbang (test) and Lantus® (reference) in healthy volunteers. Subjects received subcutaneous administration of the insulin glargine formulation (0.4 U/kg) on two occasions for the test and reference drug, respectively, and a 20% dextrose solution was infused at variable rate to clamp the blood glucose concentrations at 0.3 mmol/L below the subjects' fasting glucose for 24 h. Taking advantage of the improved sensitivity of the bioanalytical method applied and the solution of the matrix stability problem, the parent insulin glargine was determined in the vast majority of plasma samples using a fully validated UHPLC-MS/MS method. The PK characteristics of the parent insulin glargine were revealed for the first time: after subcutaneous injection, concentrations of the parent insulin glargine increased to a relative high level within 3 h, and then, a relatively flat concentration-time profile lasting for at least 12 h post-dose was observed. For the first time, the pharmacokinetic parameters of the parent insulin glargine were used as endpoints for similarity evaluation, which complied with the regulatory guidance better and made the similarity conclusion more powerful. The ratios of geometric means of all PK and PD endpoints were close to 100.00%. For the PK endpoints (AUC0-24h, Cmax, AUC0-12h, and AUC12-24h of the parent insulin glargine and its metabolite M1), the 90% confidence intervals of geometric mean ratios of test to reference were entirely contained within 80.00%-125.00%. For the PD endpoints [AUCGIR(0-24h), GIRmax, AUCGIR(0-12h), and AUCGIR(12-24h)], the 95% confidence intervals of geometric mean ratios of test to reference were entirely contained within 80.00%-125.00%. Based on the above mentioned results, it can be concluded that the PK and PD characteristics of the biosimilar drug developed by Wanbang are similar to those of Lantus.
