Bruton tyrosine kinase (Btk) is expressed in B-lymphocytes, myeloid cells and platelets, and Btk-inhibitors (BTKi) are used to treat patients with B-cell malignancies, developed against autoimmune diseases, have been proposed as novel antithrombotic drugs, and been tested in patients with severe COVID-19. However, mild bleeding is …
Background: . Covalent Bruton tyrosine kinase inhibitors (BTKi) have transformed the treatment landscape of mantle cell lymphoma (MCL). Despite the efficacy of covalent BTKi, treatment failure often occurs through development of resistance or intolerance. Pirtobrutinib, a highly selective, non-covalent (reversible) BTKi, inhibits both wildtype and …
In patients with R/R MCL previously treated with a BTKi, CAR T-cell therapy with brexu-cel or lisocabtagene maraleucel (liso-cel) resulted in high response rates and improved survival [12••, 52].In ZUMA-2, brexu-cel in patients with R/R MCL resulted in an ORR of 93% with 67% of patients achieving CR (median follow-up, 17.5 months); …

2 TREATMENT STATUS OF BTKi IN B-CELL LYMPHOMA. In a study of ibrutinib monotherapy for treatment-naïve (TN) or refractory (R/R) CLL/SLL patients, the overall response rate (ORR) was 87% for TN patients and 89% for R/R patients, and the five-year progression-free survival (PFS) rates were 92% and 44%, respectively. 8 …
A review. Bruton tyrosine kinase inhibitors (BTKi) have significantly changed the treatment landscape for patients with B-cell malignancies, including chronic lymphocytic leukemia, Waldenstrom macroglobulinemia, mantle cell lymphoma, and marginal zone lymphoma. Unfortunately, patients with BTKi-resistant disease have shortened survival.
Purpose of Review The purpose of this review is to summarize the epidemiology, mechanisms, and management of cardiovascular complications of Bruton's Tyrosine Kinase inhibitors (BTKIs). Recent Findings Ibrutinib increases the risk of atrial fibrillation, bleeding, and hypertension compared with non-BTKI therapies. The evidence …
Patients with mantle cell lymphoma progressing on Bruton's tyrosine kinase inhibitor (BTKi) have very poor prognosis and there is currently no standard of care. In this retrospective cohort study, patients progressing on BTKi received R-BAC (rituximab, bendamustine, cytarabine). Overall response rat …
August 24, 2022 (HORSHAM, PA) – The Janssen Pharmaceutical Companies of Johnson & Johnson announced today that the U.S. Food and Drug Administration (FDA) has approved IMBRUVICA ® (ibrutinib) for the treatment of pediatric patients one year and older with chronic graft-versus-host disease (cGVHD) after failure …
Bruton TK (BTK) is a nonreceptor, cytoplasmic tyrosine kinase (TK) that phosphorylates tyrosine residues with a phosphate group from adenosine triphosphate (ATP) (Figure A). 5 BTK is a signal transducer of various B cell receptors (BCRs), pattern recognition receptors (PRRs), chemokines, cytokines, and Fc receptors present on all immune cells ...

Inhibition of Bruton's Tyrosine Kinase (BTKi) is now viewed as a promising next-generation B-cell-targeting therapy for autoimmune diseases including multiple sclerosis (MS). Surprisingly little is known; however, about how BTKi influences MS disease-implicated functions of B cells. Here, we demonstrate that in addition to its …
Understanding the effect of BTKi's on humoral immunity is timely because BTKi's are widely used and vaccination against coronavirus disease 2019 is urgently needed. In 2 open-label, single-arm clinical trials, we measured the effect of BTKi's on de novo immune response against recombinant hepatitis B vaccine (HepB-CpG) and recall …
ORR per Lugano criteria 2014 is defined as the percentage of participants achieving a CR or PR. CR defined as EITHER CR by imaging (computed tomography [CT]): all lymph nodes normal (none ≥15 mm) and normal liver and spleen OR complete metabolic response (CMR): score of 1, 2 or 3 on the 5-point scale assessing fluorodeoxyglucose …
Bruton Tyrosine Kinase (BTK) inhibitors inhibit the enzyme BTK, which is a crucial part of the B-cell receptor signaling pathway. Certain B-cell leukemias and lymphomas use B-cell receptor signaling for growth and survival. The rationale for using BTK inhibitors in cancer, therefore, is to block this signaling and trigger cell death (of …
Tirabrutinib. Tirabrutinib (ONO/GS-4059, ONO-WG-307), known as the second generation of BTK inhibitor, shows potent and selective effect on inhibiting BTK by blocking auto-phosphorylation at the Tyr223 position [20,21]. From: Protein Kinase Inhibitors as Sensitizing Agents for Chemotherapy, 2019. View all Topics.
Background The more selective second-generation BTK inhibitors (BTKi) Acalabrutinib and Zanubrutinib and the first-generation BTKi Ibrutinib are highlighted by their clinical effectiveness in mantle cell lymphoma (MCL), however, similarities and differences of their biological and molecular effects on anti-survival of MCL cells induced by these BTKi …
Bruton's tyrosine kinase (BTK) is an essential component of multiple signaling pathways that regulate B cell and myeloid cell proliferation, survival, and functions, making it a promising therapeutic target for various B cell malignancies and inflammatory diseases. Five small molecule inhibitors have shown remarkable efficacy and have been approved …
