RESUMEN
AIM: To compare the clinical efficacy and safety of glargine-U100 (Lantus/Gla-100) with glargine-U300 (Toujeo/Gla-300) in adult patients with type 2 diabetes (T2D) and type 1 diabetes (T1D). MATERIALS AND METHODS: A literature search on Gla-300/Gla-100 in diabetes management was conducted using the MEDLINE/Embase/Cochrane databases from inception to 10 January 2021. Eligible studies considered for inclusion were parallel-design, randomized controlled trials (RCTs). The Cochrane risk-of-bias tool was used to evaluate the quality of the included studies. The random-effects model was applied for interpretation of the results. RESULTS: Of 5348 records screened, 592 were assessed for eligibility and 15 RCTs were considered for data extraction and meta-analysis (T2D [N = 10; n = 7082]; T1D [N = 5; n = 2222]). In patients with T1D, all safety parameters were comparable between Gla-100 and Gla-300. In T2D, statistically significant differences were observed in favour of Gla-300 over Gla-100 for nocturnal and total hypoglycaemia. For efficacy parameters, a statistically and clinically significant difference favouring Gla-100 in basal insulin dose requirement was observed for both T2D and T1D. Change in HbA1c showed a statistically but not clinically significant reduction with Gla-100 compared with Gla-300 in T1D. Statistically significant but clinically less relevant differences favoured Gla-300 for control of body weight in T1D and T2D and Gla-100 for fasting blood glucose in T2D. CONCLUSIONS: Gla-100 and Gla-300 had comparable efficacy and safety profiles in both T1D and T2D populations. Gla-300 showed a lower risk of nocturnal and total hypoglycaemia, significant in insulin-experienced/exposed patients with T2D. Patients on Gla-300 required significantly more units of insulin daily than the Gla-100 group to achieve equivalent efficacy.

AIM: To establish the pharmacokinetic (PK) and pharmacodynamic (PD) equivalence of proposed biosimilar Insulin N (Biocon's Insulin-N; Biocon Biologics Ltd., Bangalore, India) and US-licensed Humulin® N (Humulin-N; Eli Lilly and Company, Indianapolis, IN, USA) in healthy subjects. MATERIALS AND METHODS: This was a phase-1, single-centre, double-blind, randomized, three-period, six-sequence, partially replicated, crossover, 24-h euglycaemic clamp study. Overall, 90 healthy subjects were randomized, of whom 85 completed the study. The subjects received either two single doses of Biocon's Insulin-N and a single dose of Humulin-N or two single doses of Humulin-N and a single dose of Biocon's Insulin-N subcutaneously at a dose of 0.4 IU/kg. The primary PK endpoints were the area under the insulin concentration-time curve from 0 to 24 h (AUCins.0-24h ) and the maximum insulin concentration (Cins.max ). The primary PD endpoints were the area under the glucose infusion rate (GIR) curve from 0 to 24 h (AUCGIR.0-24h ) and the maximum GIR (GIRmax ). RESULTS: Biocon's Insulin-N was found to be equivalent to Humulin-N for the primary PK (geometric 90% confidence interval for the least squares mean ratio: AUCins.0-24h , 100.98%-115.66% and Cins.max , 95.91%-110.16%) and PD endpoints (intra-subject variability ≥0.294; 95% upper confidence interval [(µT - µR)2 - θσ2 WR] <0; point estimates of geometric least squares mean ratio: AUCGIR.0-24h , 104.61% and GIRmax , 100.81%). The safety profile of Biocon's Insulin-N was similar to that of Humulin-N, and no serious adverse events were reported. CONCLUSION: PK and PD equivalence was shown between Biocon's Insulin-N and Humulin-N in healthy subjects, and both treatments were well tolerated and considered safe.

AIM: To establish equivalence in the pharmacokinetic (PK) and pharmacodynamic (PD) endpoints between proposed biosimilar Insulin-R (Biocon's Insulin-R) and Humulin® R using the euglycaemic clamp technique in healthy subjects. MATERIALS AND METHODS: In this phase-1 automated euglycaemic glucose clamp study, 42 healthy subjects were randomized (1:1) to receive a single dose of 0.3 IU/kg of Biocon's Insulin-R and Humulin-R. Plasma insulin concentrations and glucose infusion rates (GIRs) were assessed over 12 hours. Primary PK endpoints were area under the insulin concentration-time curve from 0 to 12 hours (AUCins.0-12h ) and maximum insulin concentration (Cins.max ). Primary PD endpoints were area under the GIR time curve from 0 to 12 hours (AUCGIR.0-12h ) and maximum GIR (GIRmax ). RESULTS: Equivalence was demonstrated between Biocon's Insulin-R and Humulin-R for the primary PK and PD endpoints. The 90% confidence intervals were within 80.00% to 125.00% limits. The PK and PD profiles were comparable. There were no significant differences in the safety profiles of the two treatments, and no serious adverse events were reported. CONCLUSION: PK and PD equivalence was demonstrated between Biocon's Insulin-R and Humulin-R in healthy subjects. Treatment with Biocon's Insulin-R and Humulin-R was well tolerated.

AIM: To establish the pharmacokinetic (PK) and pharmacodynamic (PD) equivalence of proposed biosimilar insulin 70/30 (Biocon's Insulin-70/30) and HUMULIN® 70/30 (HUMULIN-70/30; Eli Lilly and Company, IN). MATERIALS AND METHODS: In this phase 1, automated euglycaemic glucose clamp study, 78 healthy subjects were randomized (1:1) to receive a single dose of 0.4 IU/kg of Biocon's Insulin-70/30 and HUMULIN-70/30. Plasma insulin concentrations and glucose infusion rates (GIRs) were assessed over 24 hours. Primary PK endpoints were area under the insulin concentration-time curve from 0 to 24 hours - AUCins.0-24h - and maximum insulin concentration - Cins.max . Primary PD endpoints were area under the GIR time curve from 0 to 24 hours - AUCGIR.0-24h - and maximum GIR - GIRmax . RESULTS: Equivalence was shown between Biocon's Insulin-70/30 and HUMULIN-70/30 for the primary PK/PD endpoints. The 90% confidence intervals of the treatment ratios were entirely within the acceptance range of 80.00%-125.00%. The secondary PK/PD profiles were also comparable. There were no clinically relevant differences in the safety profiles of the two treatments and no serious adverse events were reported. CONCLUSION: PK/PD equivalence was demonstrated between Biocon's Insulin-70/30 and HUMULIN-70/30 in healthy subjects. Treatment with Biocon's Insulin-70/30 and HUMULIN-70/30 was well tolerated.

PURPOSE: The phase 3 HERITAGE trial demonstrated that the biosimilar trastuzumab-dkst is well tolerated with similar efficacy (measured by overall response rate [ORR] and progression-free survival [PFS]) compared with originator trastuzumab combined with taxane followed by monotherapy in patients with HER2-positive metastatic breast cancer (MBC). Herein, we present final overall survival (OS) from HERITAGE. METHODS: HERITAGE is a multicenter, double-blind, randomized, parallel-group study. Patients were randomized 1:1 to receive trastuzumab-dkst or trastuzumab plus taxane followed by continued monotherapy until disease progression. Overall survival was to be assessed at 36 months or after 240 deaths, whichever occurred first, as observed from time of randomization of last patient. RESULTS: At the final analysis (36 months), 242 patients in the intention-to-treat population had died during the study: 116 and 124 in the trastuzumab-dkst and trastuzumab groups, respectively, and 1 untreated patient from each treatment group. Median OS by Kaplan-Meier analysis was 35.0 months with trastuzumab-dkst and 30.2 months with trastuzumab. Evaluation of PFS showed a median of 11.1 months in both treatment groups. No new safety concerns were reported from week 48 until the end of the survival follow-up. CONCLUSION: This is the first phase 3 trial of a trastuzumab biosimilar to report long-term survival data similar to originator trastuzumab in patients with MBC. The comparable long-term OS between the trastuzumab-dkst and originator trastuzumab groups further supports the similarity of trastuzumab-dkst with originator trastuzumab and establishes trastuzumab-dkst as a safe and effective treatment option for patients with HER2-positive MBC.

Design of experiments (DOE), a component of Quality by Design (QbD), is systematic and simultaneous evaluation of process variables to develop a product with predetermined quality attributes. This article presents a case study to understand the effects of process variables in a bead milling process used for manufacture of drug nanoparticles. Experiments were designed and results were computed according to a 3-factor, 3-level face-centered central composite design (CCD). The factors investigated were motor speed, pump speed and bead volume. Responses analyzed for evaluating these effects and interactions were milling time, particle size and process yield. Process validation batches were executed using the optimum process conditions obtained from software Design-Expert® to evaluate both the repeatability and reproducibility of bead milling technique. Milling time was optimized to <5 h to obtain the desired particle size (d90 < 400 nm). The desirability function used to optimize the response variables and observed responses were in agreement with experimental values. These results demonstrated the reliability of selected model for manufacture of drug nanoparticles with predictable quality attributes. The optimization of bead milling process variables by applying DOE resulted in considerable decrease in milling time to achieve the desired particle size. The study indicates the applicability of DOE approach to optimize critical process parameters in the manufacture of drug nanoparticles.

BACKGROUND: Itolizumab, an anti-CD6 monoclonal antibody, down-regulates COVID-19-mediated inflammation and the acute effects of cytokine release syndrome. This study aimed to evaluate the safety and efficacy of itolizumab in hospitalized COVID-19 patients with PaO2/FiO2 ratio (PFR) ≤200 requiring oxygen therapy. RESEARCH DESIGN AND METHODS: This multicenter, single-arm, Phase 4 study enrolled 300 hospitalized adults with SARS-CoV-2 infection, PFR ≤200, oxygen saturation ≤94%, and ≥1 elevated inflammatory markers from 17 COVID-19 specific tertiary Indian hospitals. Patients received 1.6 mg/kg of itolizumab infusion, were assessed for 1 month, and followed-up to Day 90. Primary outcome measures included incidence of severe acute infusion-related reactions (IRRs) (≥Grade-3) and mortality rate at 1 month. RESULTS: Incidence of severe acute IRRs was 1.3% and mortality rate at 1 month was 6.7% (n = 20/300). Mortality rate at Day 90 was 8.0% (n = 24/300). By Day 7, most patients had stable/improved SpO2 without increasing FiO2 and by Day 30, 91.7% patients were off oxygen therapy. Overall, 63 and 10 patients, respectively, reported 123 and 11 treatment-emergent adverse events up to Days 30 and 90. No deaths were attributable to itolizumab. Patient-reported outcomes showed gradual and significant improvement for all five dimensions on EQ-5D-5L. CONCLUSION: Itolizumab demonstrated acceptable safety with a favorable prognosis in hospitalized COVID-19 patients.

BACKGROUND AND OBJECTIVES: MYL-1402O is a bevacizumab (Avastin®) biosimilar. Pharmacokinetic and safety similarity of MYL-1402O and reference Avastin® authorized in the European Union (EU-Avastin®) and the US (US-Avastin®) was demonstrated in healthy subjects (phase I, NCT02469987). The key objectives of this study were to establish a population pharmacokinetic (PopPK) model on pooled data from the phase I and phase III clinical studies to assess pharmacokinetic linearity of MYL-1402O and Avastin® across dose ranges, to assess the pharmacokinetic similarity of MYL-1402O and Avastin® in patients with non-squamous non-small cell lung cancer (nsNSCLC), and to explore potential covariates to account for systematic sources of variability in bevacizumab exposure. METHODS: Efficacy and safety of MYL-1402O compared with EU-Avastin® was investigated in a multicenter, double-blind, randomized, parallel-group study in patients with stage IV nsNSCLC (phase III, NCT04633564). PopPK models were developed using a nonlinear mixed effects approach (NONMEM® 7.3.0). RESULTS: The pharmacokinetics of Avastin® and MYL-1402O were adequately described with a two-compartment linear model. Fourteen covariates were found to be statistically significant predictors of bevacizumab pharmacokinectics. The impact of each covariate on area under the concentration-time curve, half-life, and maximum plasma concentration was modest, and ranges were similar between the treatment groups, MYL-1402O and EU-Avastin®, in patients with nsNSCLC. The pharmacokinectics of bevacizumab appeared to be linear. CONCLUSIONS: PopPK analysis revealed no significant differences between pharmacokinetics of MYL-1402O and Avastin® in patients with nsNSCLC. The developed PopPK model was considered robust, as it adequately described bevacizumab pharmacokinetics in healthy participants and nsNSCLC patients.

BACKGROUND: Efficacy and safety of ultra-rapid acting oral prandial insulin Tregopil was compared with insulin aspart (IAsp) in patients with type 2 diabetes (T2D) on insulin glargine and metformin. RESEARCH DESIGN AND METHODS: In this open-label, active-controlled trial, patients with T2D, HbA1c ≥7%-≤9% and 2-h postprandial glucose (PPG) ≥180 mg/dL were randomized 1:1:1 to Tregopil (30 mg, n = 30; 45 mg, n = 31) and IAsp, n = 30. Primary outcome was change from baseline (CFB) in HbA1c at week 24. Secondary outcomes included PPG excursion (PPGE) and PPG assessed from standardized test meal (STM) and 9-point self-monitored blood glucose. RESULTS: The observed mean HbA1c did not improve at week 24 in Tregopil groups (30 mg [0.15%], 45 mg [0.22%] vs. a reduction in IAsp group [-0.77%]). Combined Tregopil group showed better 1-h PPGE control versus IAsp following STM (CFB, estimated treatment difference, 95% CI, -45.33 mg/dL [-71.91, -18.75], p = 0.001) and 1-h PPG trended toward better control. Tregopil showed lower PPGE at 15 min versus IAsp. Clinically significant hypoglycemia was lower with Tregopil versus. IAsp (rate ratio: 0.69). CONCLUSIONS: Tregopil demonstrated an ultrafast, short-duration prandial profile with good safety. While Tregopil's early postprandial effects were comparable to IAsp, its late postprandial effects were inferior. TRIAL REGISTRATION: The trial is registered at ClinicalTrials.gov (CT.gov identifier: NCT03430856).

Objective: Efficacy and safety of Itolizumab, an immunomodulatory mAb, in treating moderate-to-severe acute respiratory distress syndrome (ARDS) due to cytokine release in COVID-19 patients was evaluated in a multi-centric, open-label, two-arm, controlled, randomized, phase-2 study.Methods: Patients were randomized (2:1) to Arm-A (best supportive care [BSC]+Itolizumab) and Arm-B (BSC). Primary outcome of interest was reduction in mortality 30-days after enrollment.Results: Thirty-six patients were screened, five treated as first-dose-sentinels and rest randomized, while four patients were screen-failures. Two patients in Arm-A discontinued prior to receiving one complete infusion and were replaced. At end of 1-month, there were three deaths in Arm-B, and none in Arm-A (p = 0.0296; 95% CI = -0.3 [-0.61, -0.08]). At end of study, more patients in Arm-A had improved SpO2 without increasing FiO2 (p = 0.0296), improved PaO2 (p = 0.0296), and reduction in IL-6 (43 vs 212 pg/ml; p = 0.0296) and tumor necrotic factor-α (9 vs 39 pg/ml; p = 0.0253) levels. Transient lymphopenia (Arm-A: 11 patients) and infusion reactions (7 patients) were commonly reported treatment-related safety events.Conclusion: Itolizumab is a promising, safe and effective immunomodulatory therapy for treatment of ARDS due to cytokine release in COVID-19 patients, with survival and recovery-benefit.

Aims: Preclinical comparative similarity studies of trastuzumab-dkst, a Herceptin® biosimilar, are reported. Materials & methods: Primary sequence and higher order structure and pharmacological mechanisms of action were compared using multiple techniques. Pharmacokinetics and repeat-dose toxicity were assessed in cynomolgus monkeys. Results: Primary structures were identical; secondary and tertiary structures were highly similar. Non-significant differences were observed for charge heterogeneity. Twelve of 13 glycan species were highly similar, with slightly higher total mannose levels in trastuzumab-dkst. FcγR and FcRn binding activity was highly similar. Each drug equally inhibited HER2+ cell proliferation, demonstrating equivalent relative potency in mediating HER2+ cell cytolysis by antibody-dependent cellular cytotoxicity. Pharmacokinetic and toxicological profiles in cynomolgus monkeys were similar. Conclusion: Trastuzumab-dkst, US-licensed trastuzumab and EU-approved trastuzumab demonstrate high structural and functional similarity.

BACKGROUND: Trastuzumab-dkst is a biosimilar of trastuzumab. The phase 3 HERITAGE trial demonstrated equivalent overall response rate (ORR) with trastuzumab-dkst or originator trastuzumab at 24 weeks in patients with HER2-positive metastatic breast cancer receiving chemotherapy. We now present the correlation of ORR with progression-free survival (PFS) for maintenance monotherapy with trastuzumab-dkst vs trastuzumab at 48 weeks of treatment, and the safety, tolerability, and immunogenicity. METHODS: HERITAGE is a multicenter, double-blind, randomized, parallel-group, phase 3 study. Patients were randomized 1:1 to receive trastuzumab-dkst or trastuzumab in combination with taxane followed by continued monotherapy until disease progression. The analysis included PFS at 48 weeks to support the primary efficacy endpoint of ORR and safety, tolerability, and immunogenicity of trastuzumab-dkst vs trastuzumab as maintenance monotherapy. RESULTS: Of 500 randomized patients, 342 entered the monotherapy phase; 214 patients received ≥48 weeks of treatment. There were no statistically significant differences between PFS, ORR, or interim overall survival at week 48 between trastuzumab-dkst and trastuzumab. Week 24 ORR was highly correlated with week 48 PFS (rb = 0.75). Cumulative treatment-emergent adverse events (TEAEs) and serious AEs were similar in both groups, with few grade ≥3 TEAEs. Immunogenicity was low and similar in both groups at 48 weeks. CONCLUSION: The correlation between ORR and PFS supports the design of first-line metastatic trials assessing biosimilar trastuzumab. Overall, trastuzumab-dkst and trastuzumab were well tolerated with similar efficacy, including ORR and PFS, in combination with a taxane followed by monotherapy.
