The Ministry of Health of the Russian Federation has authorized a Russian originator drug for the treatment of unresectable or metastatic melanoma. The product was developed by BIOCAD, a biotechnology company; it is a fixed dose combination of two monoclonal antibodies, nurulimab and prolgolimab.
The Ministry of Health of the Russian Federation has authorized prolgolimab for the treatment of lung cancer, expanding the current list of indications. Authorization of the new indication was based, among other things, on the results of the BCD-100-3/DOMAJOR Phase III clinical trial.
Background: BCD-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 efcacy and safety of BCD-021 and reference bevacizumab in combination with paclitaxel and carboplatin in a frst-line treatment of inoperable or advanced non-squamous non-smallcell lung cancer (NSCLC). Methods: Patients 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 efcacy of BCD-021 and reference bevacizumab. Equivalence margins for 95% CI for the diference in the overall respmore...
The aim of this double-blind, placebo-controlled, phase III CORONA clinical trial was to evaluate the efficacy and safety of IL-6 receptor inhibitor levilimab (LVL) in subjects with severe COVID-19. The study included 217 patients. The eligible were men and non-pregnant women aged 18 years or older, hospitalized for severe COVID-19 pneumonia. 206 subjects were randomized (1:1) to receive single subcutaneous administration of LVL 324 mg or placebo, both in combination with standard of care (SOC). 204 patients received allocated therapy. After the LVL/placebo administration in case of deterioration of symptoms, the investigator could perform a single open-label LVL 324 mg administration as the rescue therapy. The primary efficacy endpoint was the proportion of patients with sustained clinical improvement on the 7-category ordinal scale on Day 14. All efficacy data obtained after rescue therapy administration were considered missing. For primary efficacy analysis, all subjects with missinmore...
Prolgolimab is an IgG1 anti–PD-1 (programmed cell death protein 1) monoclonal antibody containing the Fc-silencing ‘LALA’ mutation. We assessed the efficacy and safety of two dosing regimens of prolgolimab in patients with advanced melanoma in a multicenter open-label parallel-arm phase II trial (MIRACULUM). We present the final analysis after 1 year of follow-up and additional efficacy results from 2 years of follow-up.
BCD-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.
BCD-020 is a proposed rituximab biosimilar, which has shown high similarity to rituximab in quality and nonclinical studies in vitro and in vivo. International multicenter clinical trial was conducted to compare efficacy and safety of BCD-020 and reference rituximab in adult (older than 18 years) patients with indolent lymphomas (follicular lymphoma grade 1-2, splenic marginal zone lymphoma, and nodal marginal zone lymphoma). Pharmacokinetics, pharmacodynamics, and immunogenicity were also studied. Patients with no previous biologic treatment for lymphoma were randomly assigned 1:1 to receive BCD-020 or comparator 375 mg/m2 for 4 weeks. Primary study outcome was day 50 overall response rate defined as complete or partial remission. Equivalence range was −20% to 20% for 95% CI for overall response rates difference. Secondary outcomes included adverse events, pharmacokinetics, pharmacodynamics, and immunogenicity. One hundred seventy-four patients were enrolled, 89 in BCD-020 arm and 85 more...
OBJECTIVES: Netakimab (NTK) is a humanised monoclonal antibody targeting interleukin-17A, previously investigated in a phase 1 trial in healthy volunteers. Here, we report the results of a phase 2 trial, conducted to assess safety and pharmacokinetics (PK), to establish a therapeutic dose of NTK in a target population of patients with active ankylosing spondylitis (AS). METHODS: 89 patients with active AS, despite non-steroidal anti-inflammatory (NSAID) drug treatment, were randomised to receive 40, 80 or 120 mg of subcutaneous NTK or placebo at weeks 0, 1, 2 and q2wk thereafter until week 12. The primary endpoint was to achieve a proportion of patients with ≥20% improvement in Assessment of Spondyloarthritis. RESULTS: Rates of ASAS20 response at week 16 for NTK with 95%CI for difference in ASAS20 rates NTK vs. placebo were 72.73% [1.69%;58.05%], 81.82% [12.36%;65.56%], 90.91% [23.71%;72.39%] at doses of 40, 80 and 120 mg. The response rate in the placebo arm was 42.86%. The pre-specifmore...
BCD-055 is a biosimilar of innovator infliximab (IFX). Here we present the 54-week results from phase 3 clinical study in patients with rheumatoid arthritis (RA). The aim of this study was to demonstrate the equivalent efficacy and safety of BCD-055 and IFX in patients with active rheumatoid arthritis. 426 adults with active RA were enrolled. Patients were randomized into 2 study arms in 2:1 ratio to receive BCD-055 or IFX innovator in dose of 3 mg/kg at week 0, 2, 6 and then every 8 weeks up to week 54. Primary efficacy endpoint was the rate of American College of Rheumatology (ACR) 20 response at week 14. The equivalence margin was set as 15%. Immunogenicity and safety were also assessed. Rate of ACR20 at week 14 in PP (Per-Protocol) population was 71.2% in BCD-055 group and 67.9% in IFX group. Difference in ACR20 rates between groups was 3.2% with 95% CI [- 7.0%; 13.5%] (р = 0.587). Throughout 54-week study period, both groups were characterized by similar rates of ACR20/50/70 respomore...
PD-1/PD-L1-based therapy has been named a revolution in cancer treatment. By the end of 2018, more than 100 anti-PD-1 and anti-PD-L1 antibodies were in various stages of development, and more than 2000 clinical trials with their use have been registered. Characterization of such antibodies requires a bioassay to determine their biological activity. In this study, we developed a cell-based bioassay for analyzing the activity of anti-PD-1 and anti-PD-L1 antibodies. We chose reporter system consisting of two cell lines and compared several approaches for activation of effector cell line based on superantigens, soluble anti-CD3 antibodies, transmembrane anti-CD3 antibodies, chimeric antigenic receptors (CARs) and bispecific T-cell engager antibodies. The bispecific T-cell engager antibodies offer several advantages over the other approaches. We characterized the bioassay and demonstrated its applicability for analyzing the activity of anti-PD-1 and anti-PD-L1 antibodies. The proposed bioasmore...
