Efficacy and safety of biosimilar insulins compared to their reference products: A systematic review.

ABSTRACT: For nearly a century, no generic form of insulin has been available in the United States. However, the first biosimilar insulin, Basaglar, was approved by the U.S. Food and Drug Administration in 2015, and subsequently Admelog and Lusduna in 2017.To summarize the scientific evidence comparing the safety, efficacy, pharmacokinetics, and pharmacodynamics of biosimilar and reference insulin products.We conducted a systematic review using PubMed, Cochrane, Embase, Latin America and Caribbean Health Sciences, South Asian Database of Controlled Clinical Trials, and IndiaMED from their inception through January 14, 2018.We included randomized controlled trials (RCTs) comparing safety, clinical efficacy, pharmacokinetics and pharmacodynamics of any biosimilar insulin with a reference product in adults regardless of sample size and location.Two researchers independently reviewed all titles, abstracts and text; extracted data; and performed quality assessments.Efficacy, safety, pharmacokinetics, and pharmacodynamics of biosimilar and reference insulin products.Of 6945 articles screened, 11 studies were included in the data synthesis. LY2963016, Basalog, Basalin, and MK-1293 were compared to Lantus while SAR342434 was compared to Humalog. Three trials enrolled healthy volunteers, five enrolled type 1 diabetics, and two enrolled type 2 diabetics. One study enrolled both healthy and type 1 diabetics. Of the eleven studies, six examined pharmacokinetic and/or pharmacodynamic parameters and five examined clinical efficacy and immunogenicity. All studies included adverse events. All PK and/or PD studies showed that comparable parameters of biosimilar and reference products were within the pre-specified equivalence margins. Clinical studies suggested similar clinical efficacy and immunogenicity. Adverse events were similar between the groups across all studies.Few published studies have compared biosimilar and reference insulins, though those that did suggest that the biosimilars have comparable safety and clinical efficacy as its reference product.

Project description:BackgroundIncreasing availability of competing biosimilar alternatives makes it challenging to make treatment decisions. The purpose of this review is to evaluate the comparative efficacy and safety of ultra-long-/long-/intermediate-acting insulin products and biosimilar insulin compared to human/animal insulin in adults with type 1 diabetes mellitus (T1DM).MethodsMEDLINE, EMBASE, CENTRAL, and grey literature were searched from inception to March 27, 2019. Randomized controlled trials (RCTs), quasi-experimental studies, and cohort studies of adults with T1DM receiving ultra-long-/long-/intermediate-acting insulin, compared to each other, as well as biosimilar insulin compared to human/animal insulin were eligible for inclusion. Two reviewers independently screened studies, abstracted data, and appraised risk-of-bias. Pairwise meta-analyses and network meta-analyses (NMA) were conducted. Summary effect measures were mean differences (MD) and odds ratios (OR).ResultsWe included 65 unique studies examining 14,200 patients with T1DM. Both ultra-long-acting and long-acting insulin were superior to intermediate-acting insulin in reducing A1c, FPG, weight gain, and the incidence of major, serious, or nocturnal hypoglycemia. For fasting blood glucose, long-acting once a day (od) was superior to long-acting twice a day (bid) (MD - 0.44, 95% CI: - 0.81 to - 0.06) and ultra-long-acting od was superior to long-acting bid (MD - 0.73, 95% CI - 1.36 to - 0.11). For weight change, long-acting od was inferior to long-acting bid (MD 0.58, 95% CI: 0.05 to 1.10) and long-acting bid was superior to long-action biosimilar od (MD - 0.90, 95% CI: - 1.67 to - 0.12).ConclusionsOur results can be used to tailor insulin treatment according to the desired results of patients and clinicians and inform strategies to establish a competitive clinical market, address systemic barriers, expand the pool of potential suppliers, and favor insulin price reduction.Prospero registrationCRD42017077051.

Project description:BackgroundMultiple switches (transitions) between biosimilars of the same reference biologic are now a reality, and they are expected to become more common in the future as more biosimilars enter the market. Switching between two biosimilars of the same reference biologic is generally driven by affordability, formulary requirements, or the relocation/travel of the patient. Evidence of whether switching between biosimilars of the same reference biologic provides similar safety and efficacy profiles is reviewed here.MethodsA systematic search was undertaken using electronic databases (to December 2021): Biosis, Embase, MEDLINE, and EBM Reviews/Cochrane Database of Systematic Reviews via Ovid. Publications were evaluated for effectiveness and/or safety data linked to switching from one biosimilar to another.ResultsThe systematic search yielded 982 citations. After eliminating duplicates, 626 citations remained for the initial title/abstract screening phase. Following the initial screening, 240 records were chosen; more thorough examination yielded 35 citations. After comprehensive screening and expert advice, 23 studies were selected, of which 13 were published in peer-reviewed journals; the remainder have been published as abstracts. Overall, 3657 patients were included in these studies. All studies were observational in nature; no randomized clinical trials were identified. The studies were heterogeneous in size, design, and endpoints. Across the studies, data are provided on safety, effectiveness, immunogenicity, pharmacokinetics, patient retention, patient and physician perceptions, and drug-use patterns. The majority of studies examined switches between biosimilar infliximabs, although switches between biosimilar adalimumabs, etanercepts, and rituximabs were also identified. Two use-pattern studies and one case report were also detected and are discussed.ConclusionWithin the limitations of this systematic review, available data suggests that biosimilar-to-biosimilar switching is a safe and effective clinical practice, although it is not covered by current health authority regulations or guidance. No reduction in effectiveness or increase in adverse events was detected in biosimilar-to-biosimilar switching studies conducted to date.

Project description:BackgroundPertuzumab is a humanized monoclonal antibody for the treatment of breast cancer. HLX11 is a biosimilar of pertuzumab developed by Shanghai Henlius Biotech, Inc. We conducted a bioequivalence study for HLX11 and pertuzumab (United States [US]-, European Union [EU]-, and China [CN]-approved products).ObjectivesThis study compared the biosimilarity in pharmacokinetics (PK), safety, and immunogenicity between HLX11 and reference pertuzumab (approved in the US, the EU, and CN) in healthy Chinese male participants after a single infusion and further characterized the PK profile of HLX11.MethodsEligible individuals were randomized 1:1:1:1 to receive a single dose of 420 mg HLX11, US-, EU-, or CN-pertuzumab via intravenous infusion over 60 min. The primary endpoints were maximum serum drug concentration (Cmax), area under the serum concentration-time curve (AUC) from time 0 to time of the last quantifiable concentration (AUC0-t), and AUC from time 0 to infinity (AUC0-∞). PK bioequivalence was established if the 90% confidence intervals (CIs) of the geometric mean ratios of the primary endpoints were between 80.0 and 125.0%. Secondary endpoints included other PK parameters, safety, and immunogenicity.ResultsA total of 160 participants were enrolled and randomly assigned to each group (n = 40 per group). The 90% CIs of the geometric mean ratios of the primary endpoints were all within the prespecified equivalence margins (HLX11 vs. pertuzumab [US-, EU-, CN-approved products]: Cmax 97.03-115.06%, 91.39-109.80%, 94.53-110.65%; AUC0-t 87.65-99.68%, 87.07-100.79%, 86.29-101.09%; AUC0-∞ 87.66-99.90%, 87.54-101.05%, 89.23-103.20%). The incidence of adverse drug reactions was comparable across the four groups. The presence of anti-drug antibodies or neutralizing antibodies had no obvious effect on PK.ConclusionThe PK, safety, and immunogenicity of HLX11 were highly similar to those of reference pertuzumab (US-, EU-, CN-approved products). The established bioequivalence supports further clinical trials of HLX11 in cancer treatment.Trial registrationThis study was registered with ClinicalTrials.gov (NCT04411550) and Chinadrugtrials.org.cn (CTR20200618).

Project description:BackgroundBCD-021 is a bevacizumab biosimilar which was shown to be equivalent to reference bevacizumab in a wide panel of physicochemical studies as well as preclinical studies in vitro and in vivo. International multicenter phase III clinical trial was conducted to compare efficacy and safety of BCD-021 and reference bevacizumab in combination with paclitaxel and carboplatin in a first-line treatment of inoperable or advanced non-squamous non-small-cell lung cancer (NSCLC).MethodsPatients with no previous treatment for advanced non-squamous NSCLC were randomly assigned 3:2 to BCD-021 or reference bevacizumab and were treated with bevacizumab + paclitaxel + carboplatin. Therapy continued for 6 cycles (every 3 weeks), until progression of the disease or unbearable toxicity. The primary study endpoint was the overall response rate. The study goal was to prove the equivalent efficacy of BCD-021 and reference bevacizumab. Equivalence margins for 95% CI for the difference in the overall response rates were set at [-18%; 18%], for 90% CI for the ratio of overall response rate were set at [67%; 150%].ResultsIn total 357 patients were enrolled in the study, 212 in the BCD-021 group and 145 in the reference bevacizumab group. The ORR was 34.63% in the BCD-022 group and 33.82% in the reference bevacizumab group. Limits of 95% CI for the difference in overall response rates between the groups were [-9.47%; 11.09%]. Limits of 90% CI for the ratio of overall response rate between the groups were [79.6%; 131.73%]. For both approaches CI lied within predetermined equivalence margins. Profile of adverse events (AEs) was similar between the groups (any AEs were reported in 86.89% of patients in BCD-021 group and 89.05% of patients in reference group). No unexpected adverse reactions were reported throughout the study. No statistically significant differences regarding anti-drug antibody occurrence rate was found between BCD-022 (n=4; 1.96%) and comparator (n=5; 3.65%). Both drug products showed low occurrence rate and short life of anti-bevacizumab antibodies. Pharmacokinetics assessment after 1st and 6th study drug injection also demonstrated equivalent PK parameters by all outcome measures.ConclusionsThus, the results of this study demonstrated therapeutic equivalence of bevacizumab biosimilar BCD-021 and referent bevacizumab drug.Trial registrationThe trial was registered with ClinicalTrials.gov (Study Number NCT01763645, date of registration 09/01/2013).

Project description:BackgroundBCD-022 is a trastuzumab biosimilar which was shown to be equivalent to reference trastuzumab in a wide panel of physicochemical studies as well as preclinical studies in vitro and in vivo. International multicenter phase III clinical trial was conducted to comparatively assess efficacy and safety of BCD-022 and reference trastuzumab in combination with paclitaxel used as the therapy of metastatic HER2(+) breast cancer. Pharmacokinetics and immunogenicity were also studied.MethodsPatients with no previous treatment for metastatic HER2(+) breast cancer were randomly assigned 1:1 to BCD-022 or reference trastuzumab and were treated with trastuzumab + paclitaxel. Therapy continued for 6 cycles of therapy (every 3 weeks), until progression of the disease or unbearable toxicity. Primary study endpoint was overall response rate. Study goal was to prove equivalent efficacy of BCD-022 and reference trastuzumab. Equivalence margins for 95% CI for difference in overall response rates were set at [- 20%; 20%].ResultsIn total 225 patients were enrolled into the study, 115 in BCD-022 arm and 110 in reference trastuzumab arm. Overall response rate was 49.6% in BCD-022 arm and 43.6% in reference trastuzumab arm. Limits of 95% CI for difference of overall response rates between arms were [(- 8.05)-19.89%], thus, they lied within predetermined equivalence margins [- 20%; 20%]. Profile of adverse events was similar between groups (any AEs were reported in 93.81% of patients in BCD-022 arm and 94.55% of patients in reference arm). No unexpected adverse reactions were reported throughout the study. No statistically significant differences regarding antibody occurrence rate (either BAb or NAb) was found between BCD-022 (n = 3; 2.65%) and comparator (n = 4; 3.64%). Both drug products are characterized with low occurrence rate and short life of anti-trastuzumab antibodies. Pharmacokinetics assessment after 1st and 6th study drug injection also demonstrated equivalent PK parameters by all outcome measures: AUC0-504, Сmах, Тmax, T1/2. Analysis of Ctrough did not reveal any significant inter-group differences as well.ConclusionsThus, results of this study have demonstrated therapeutic equivalence of trastuzumab biosimilar BCD-022 and referent trastuzumab drug.Trial registrationThe trial was registered with ClinicalTrials.gov (Study Number NCT01764022 ). The date of registration was January 9, 2013.
