MYL-1601D is a proposed biosimilar of originator insulin aspart, Novolog^®/NovoRapid^® (Ref-InsAsp-US/Ref-InsAsp-EU).

This study assessed the immunogenicity, efficacy, and safety of MYL-1601D with Ref-InsAsp-US in patients with type 1 diabetes mellitus (T1D).

This was a 24-week, open-label, randomized, phase III study. Patients were randomized 1:1 to mealtime MYL-1601D or Ref-InsAsp-US in combination with insulin glargine (Lantus SoloSTAR^®) once daily. The treatment-emergent antibody response (TEAR) rate (defined as patients who were anti-insulin antibody [AIA] negative at baseline and became positive at any timepoint post-baseline or patients who were AIA positive at baseline and demonstrated a 4-fold increase in titer values at any timepoint post-baseline) was the primary endpoint. The study also compared the change from baseline in glycated hemoglobin (HbA1c), fasting plasma glucose (FPG), prandial, basal, and total daily insulin, 7-point self-monitored blood glucose (SMBG) profiles, immunogenicity, and adverse events (AEs) including hypoglycemia.

In total, 478 patients were included in the intent-to-treat analysis (MYL-1601D: 238; Ref-InsAsp-US: 240) set. The 90% confidence interval (CI) for the primary endpoint was within the pre-defined equivalence margin of ±11.7% and the treatment differences (SE) in TEAR responders between the treatment groups was - 2.86 (4.16) with 90% CI - 9.71 to 3.99. The mean (SD) changes from baseline for HbA1c, FPG, and insulin dosages were similar in both groups at week 24. The safety profiles including hypoglycemia, immune-related events, AEs, and other reported variables were similar between the treatment groups at week 24.

MYL-1601D demonstrated similar immunogenicity, efficacy, and safety profiles to Ref-InsAsp-US in patients with T1D over 24 weeks. CLINICAL TRIAL REGISTRATION CLINICALTRIALS.GOV: NCT03760068.

Bevacizumab is a recombinant humanized monoclonal antibody that inhibits vascular endothelial growth factor-specific angiogenesis in some cancers. MYL-1402O is a proposed bevacizumab biosimilar.

The 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.

Of 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.

MYL-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).

Process chromatography is commonly used for purification of therapeutic proteins. Most chromatography skids that are used in such operations utilize single ultraviolet (UV) absorbance for monitoring and quantification of protein content. While the signal from such UV measurement is linear with respect to protein concentration at low values of protein concentrations, as the concentration increases across an eluting product peak, it goes manifold over the linear range, resulting in saturation of the UV signal and as a result incomplete quantification of the protein concentration. This can hamper our ability to decide on where to pool the process chromatography peak. It is evident that a simple, fast, and cost-effective methodology for on-line estimation of protein concentration is the need of the hour. In this paper, a multi-wavelength UV-based approach has been proposed for dilution-free on-line concentration estimation in the range of 0.8-100 g/L. Stable absorbance regions are picked up in the proposed approach from the multi-wavelength UV spectra, thereby offering a solution to the problem of saturation and non-linearity of the UV signal that is otherwise observed at higher concentrations. Further, using chemometrics tools such as principal component analysis (PCA) and partial least squares (PLS), the model has been validated for rapid quantification of protein concentration from the spectra. The predictions from the model were comparable to values measured using an existing UV-based offline method with an R² of>98%. The proposed process analytical technology (PAT) tool was successfully tested online and exhibited<8% variability and could effectively be used from capture to formulation to enable dilution-free online concentration measurement of IgG. The proposed tool is a simple, low-cost alternative to other methods and could enable integrated/continuous operations throughout the downstream train.
