Bruton tyrosine kinase Bruton tyrosine kinase (Btk) is a 659 amino acid member of a recently identified subfamily of src-related cytoplasmic tyrosine kinases (Figure 1). Expert Opinion on Investigational Drugs: Vol. Ibrutinib (Imbruvica), a small-drug inhibitor of Bruton tyrosine kinase (BTK), is currently undergoing clinical testing in patients with multiple myeloma, yet important questions on the role of BTK in myeloma biology and treatment are outstanding. Bruton’s tyrosine kinase is not essential for B cell survival beyond early developmental stages. The activation of Bruton's tyrosine kinase (Btk), a member of the Tec family of tyrosine kinases, regulates B-cell activation and development and plays an important role in antibody production. Role of Bruton's tyrosine kinase in B cell development; Btk is activated by Toll-like receptor (TLR)4 in primary macrophages and is required for normal TLR-induced IL-10 production in multiple macrophage populations. The gene contains 19 exons and the open reading frame has 1977 nucleotides. Annu Rev Immunol.

REVIEW Inhibition of Bruton´s tyrosine kinase as a novel therapeutic approach in multiple sclerosis Sebastian Torkea and Martin S. Webera,b aInstitute of Neuropathology, University Medical Center, Göttingen, Germany; bDepartment Neurology, Germany ABSTRACT Authors: Edgar Carnero Contentti, Jorge Correale View on publisher site Alert me about new mentions. Bruton tyrosine kinase inhibition is a novel therapeutic strategy targeting tumor in the bone marrow microenvironment in multiple myeloma. Harmful consequences arise when the immune system mistakes self-proteins as foreign antigens, with BTK promoting autoantibody secretion by autoreactive B cells.8,14,15 Autoimmune diseases such as multiple sclerosis (MS)16 result from this dysregulated production of autoantibodies, which leads to destruction of normal tissue.17 Malfunctioning BTK mutants have been linked to increased disease susceptibility, correlating with diminished numbers of mature B cells and immunoglobulin isotypes.18,19 BTK therefore serves as an important target for therapeutic agents that modulate innate immunity. Dose 1 of oral SAR442168 daily + placebo to match the teriflunomide tablet once daily, Oral 14 mg oral teriflunomide + placebo to match the SAR442168 tablet once daily, Annualized Adjudicated Relapse Rate : Number of confirmed protocol defined adjudicated relapses, Change in cognitive function from baseline to the EOS as assessed by the SDMT and CVLT-II where available, Time to confirmed disability improvement (CDI), defined as a ≥1.0 point decrease on the EDSS from the baseline EDSS score confirmed over at least 6 months, Brain volume loss (BVL) rate as detected by brain MRI from Month 6 to the EOS, Change in Multiple Sclerosis Quality of Life-54 (MSQoL-54) from the baseline through the EOS, Change in plasma neurofilament light chain (NfL) levels at the EOS compared to baselineC, Changes in serum immunoglobulin level at the EOS compared to baseline, Change in serum Chi3L1 levels at the EOS compared to baseline -. When the b-cell antigen receptor binds to an antigen a cascade of signals take place within the cell, which promotes the prolonged survival of the cell and cell cycle progression.

Please refer to this study by its ClinicalTrials.gov identifier (NCT number): NCT04410991. Session Title: B Cell Biology & Targets In Autoimmune & Inflammatory Disease Poster. The gene encoding the BTK molecule was isolated in 1993 and was named independently at the time as B cell progenitor kinase and agammaglobulinemia tyrosine kinase [5, 6]. However, the role of BTK in the CNS is unknown. Secondary end points included annualized relapse rate and change from baseline on the Expanded Disability Status Scale.37 Among the 267 patients randomized, those who received 75 mg evobrutinib once daily had significantly fewer gadolinium-enhancing lesions at weeks 12 through 24 compared with placebo; however, covalent binding combined with a high daily dose was found to induce liver injury.29,37 Additional statistical analysis revealed no dose response nor any effect of evobrutinib on annualized relapse rate or disability progression.37, SAR442168 is also a potent, covalent, selective, BBB-penetrant BTK inhibitor that has demonstrated a dose-dependent protection from MS induction alongside no serious medication-related adverse events in participants (with 7.5- to 120.0-mg daily doses) in a phase 1 trial (NCT04171310).38 Encouraging results from the phase 2B trial39 reported in April 2020 revealed an 85% relative reduction in new gadolinium-enhancing lesions in the 60-mg group with a mean number of new lesions of 0.13 (P = .03) compared with 0.76 in the 30-mg group, 0.77 in the 15-mg group, 1.39 in the 5-mg group, and 1.03 with placebo.40 In addition, patients in the 60-mg group demonstrated an 89% relative reduction in new or enlarging T2 hyperintense lesions (P <.0001) at 12 weeks, with a mean number of lesions of 0.23 compared with 1.30 in the 30-mg group, 1.32 in the 15-mg group, 1.90 in the 5-mg group, and 2.12 in the placebo group; however, the trial did not consider disease development readouts such as relapse rates and MS progression.40 Based on the results, manufacturer Sanofi plans to initiate 4 phase 3 pivotal trials.40, Biogen’s BIIB091 is still in early stages of development, with its ongoing phase 1 clinical trial (NCT03943056) expected to reach primary completion sometime in spring 2020.41.

However, rituximab is incapable of penetrating the blood-brain barrier (BBB) or lymphoid organs and is unsuccessful in slowing disease progression.23,28 To overcome the limitations of mAbs,28 MS treatment efforts have turned to BTK inhibitors (FIGURE).29, The ideal BTK inhibitor would be a rapidly reversible, BBB-penetrant, highly selective, modulatory approach to target B-cell activation without widespread depletion of B cells.8,9,23,30,31 Rather, the B-cell response to BCR stimuli is lowered, tolerogenic B cells are maintained, and antigen-mediated proinflammatory activation is neutralized.8,12,15,31 BTK is already a target in treatment of lymphoma, leukemia, and rheumatoid arthritis via the prominent BTK inhibitor ibrutinib.

The nervous system is consequently “short-circuited,” potentially permanently.26, Treatments for MS aim to shorten the duration and severity of relapses, prolong the time between relapses, and delay progression of disability.27 The most well-studied type of therapy targeting B cells consists of monoclonal antibodies (mAbs) that deplete B cells through mechanisms of antibody-dependent cellular cytotoxicity and apoptosis.23 Rituximab, for example, a mAb targeting the B-cell antigen CD20, depletes B cells and reduces T cells in the cerebrospinal fluid.

Bruton Tyrosine Kinase (BTK), a Tec family nonreceptor tyrosine kinase1 critical for the development of B cells and several other hematopoietic lineages2 (except for T cells, plasma cells, and natural killer cells3), is a recent focus of therapeutics.4 BTK informs immune responses by acting as an early downstream amplification enzyme of the B-cell antigen receptor (BCR)5-8 and cytokine receptor pathways.8,9 BTK signaling influences antigen presentation on B cells10 and is essential to the production of antibodies, proinflammatory cytokines and chemokines, and cell adhesion molecules.11,12 Through these mechanisms, BTK helps transmit the signals that allow immune cells to respond to foreign antigens by targeting the cells presenting them for destruction.13-15.

The lack of selective BTK inhibitors to date has partly limited progress in developing drugs that target BTK for autoimmune diseases, where the tenant is held that long term therapy in nonlife threatening diseases […] Primary Progressive Multiple Sclerosis (PPMS) Study of Bruton's Tyrosine Kinase (BTK) Inhibitor SAR442168 (PERSEUS) (PERSEUS) The safety and scientific validity of this study is the responsibility of the study sponsor and investigators.
