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...

In this paper, we describe the development of a novel statistical potential for the prediction of antibody-antigen complexes (docking), which play key role in in silico immunother- apy discovery. The developed statistical potential is then used to improve the accuracy of an existing docking algorithm. We also present a new dataset for the development and comparison of different statistical potentials and docking algorithms. One of the key features of the developed dataset is that it can be obtained almost automatically, with few optional manual steps, using the pipeline introduced in this paper.

The first global workshop on implementation of the WHO guidelines on procedures and data requirements for changes to approved biotherapeutic products adopted by the WHO Expert Committee in 2018 was held in June 2019. The workshop participants recognized that the principles based on sound science and the potential for risk, as described in the WHO Guidelines on post-approval changes, which constitute the global standard for product life-cycle management are providing clarity and helping national regulatory authorities in establishing guidance while improving time-lines for an efficient regulation of products. Consequently, the regulatory situation for post-approval changes and guideline implementation is changing but there is a disparity between different countries. While the guidelines are gradually being implemented in some countries and also being considered in other countries, the need for regional workshops and further training on post-approval changes was a common theme reiteratedmore...

Y-box binding proteins are DNA- and RNA-binding proteins with an evolutionarily ancient and conserved cold shock domain. The Y-box binding protein 1 (YB-1) is the most studied due to its abundance in somatic cells. YB-1 is involved in a variety of cellular processes, including proliferation, differentiation and stress response. Here, using Ribo-Seq and RIP-Seq we confirm that YB-1 binds a wide range of mRNAs and globally acts as a translation inhibitor. Surprisingly, YBX1 knockout results in only minor alterations in the expression of other genes, mostly caused by changes in RNA abundance. But YB-3 mRNA is an exception: it is better translated in the absence of YB-1, thereby producing an increased amount of YB-3 and thus suggesting that its synthesis is under YB-1 negative control. We have shown that the set of mRNAs bound to YB-3 is strikingly similar to that of YB-1, and that the mRNA-binding by YB-3 is enhanced in the absence of YB-1, resulting in a similar global reduction of transmore...

Protein phosphorylation cascades play a central role in the regulation of cell growth and protein kinases PKA, Sch9 and Ypk1 take center stage in regulating this process in S. cerevisiae. To understand how these kinases co-ordinately regulate cellular functions we compared the phospho-proteome of exponentially growing cells without and with acute chemical inhibition of PKA, Sch9 and Ypk1. Sites hypo-phosphorylated upon PKA and Sch9 inhibition were preferentially located in RRxS/T-motifs suggesting that many are directly phosphorylated by these enzymes. Interestingly, when inhibiting Ypk1 we not only detected several hypo-phosphorylated sites in the previously reported RxRxxS/T-, but also in an RRxS/T-motif. Validation experiments revealed that neutral trehalase Nth1, a known PKA target, is additionally phosphorylated and activated downstream of Ypk1. Signaling through Ypk1 is therefore more closely related to PKA- and Sch9-signaling than previously appreciated and may perform functionsmore...
