Description
(extracted from source data)
DESCRIPTION Acalabrutinib is an orally available second-generation, irreversible inhibitor of Bruton agammaglobulinemia tyrosine kinase (BTK), being investigated for its potential antineoplastic activity (in multiple haematologic malignancies and solid tumours), as well as a potential therapy for rheumatoid arthritis.
PHARMACODYNAMICS When a dosage of acalabrutinib 100 mg twice daily is administered, a median steady state Bruton Tyrosine Kinase (BTK) occupany of approximately ≥ 95% in peripheral blood is maintained over 12 hours allowing for the inactivation of BTK throughout the recommended dosing interval [FDA Label].; ; Additionally, it has been shown that a single dose of acalabrutinib that is four-fold the maximum recommended single dose (ie. 100 mg) does not appear to prolong QTc interval to any clinically significant extent (ie. ≥ 10 ms) [FDA Label].
MOA Mantle Cell Lymphoma (MCL) is a rare yet aggressive type of B-cell non-Hodgkin lymphoma (NHL) with poor prognosis [A31253, L1008]. Subsequently, relapse is common in MCL patients and ultimately represents disease progression [L1008].; ; Lymphoma occurs when immune system lymphocytes grow and multiply uncontrollably. Such cancerous lymphocytes may travel to many parts of the body, including the lymph nodes, spleen, bone marrow, blood, and other organs where they can multiply and form a mass(es) called a tumor. One of the main kinds of lymphocytes that can develop into cancerous lymphomas are the body's own B-lymphocytes (B-cells) [L1008].; ; Bruton Tyrosine Kinase (BTK) is a signalling molecule of the B-cell antigen receptor and cytokine receptor pathways. Such BTK signaling causes the activation of pathways necessary for B-cell proliferation, trafficking, chemotaxis, and adhesion [FDA Label].; ; Acalabrutinib is a small molecule inhibitor of BTK. Both acalabrutinib and its active metabolite, ACP-5862, act to form a covalent bond with a cysteine residue (Cys481) in the BTK active site, leading to inhibition of BTK enzymatic activity [A31253, L1008]. As a result, acalabrutinib inhibits BTK-mediated activation of downstream signaling proteins CD86 and CD69, which ultimately inhibits malignant B-cell proliferation and survival [L1008].; ; Whereas ibrutinib is typically recognized as the first-in-class BTK inhibitor [A31253], acalabrutinib is considered a second generation BTK inhibitor primarily because it demonstrates highter selectivity and inhibition of the targeted activity of BTK while having a much greater IC50 or otherwise virtually no inhibition on the kinase activities of ITK, EGFR, ERBB2, ERBB4, JAK3, BLK, FGR, FYN, HCK, LCK, LYN, SRC, and YES1 [A31253]. ; ; In effect, acalabrutinib was rationally designed to be more potent and selective than ibrutinib, all the while demonstrating fewer adverse effects - in theory - because of the drug's minimized bystander effects on targets other than BTK.
HALF-LIFE After administering a single oral dose of 100 mg acalabrutinib, the median terminal elimination half-life of the drug was found to be 0.9 (with a range of 0.6 to 2.8) hours [FDA Label].; ; The half-life of the active metabolite, ACP-5862, is about 6.9 hours [FDA Label].
DESCRIPTION Acalabrutinib is an orally available second-generation, selective and irreversible inhibitor of Bruton tyrosine kinase (BTK) , being investigated for its potential antineoplastic activity (in multiple haematologic malignancies and solid tumours), as well as a potential therapy for rheumatoid arthritis. Acalabrutinib covalently bonds to Cysteine-481 in BTK. (GtoPdb)
DESCRIPTION Acalabrutinib (ACP-196) is an orally active, irreversible, and highly selective second-generation BTK inhibitor. Acalabrutinib binds covalently to Cys481 in the ATP-binding pocket of BTK. Acalabrutinib demonstrates potent on-target effects and efficacy in mouse models of chronic lymphocytic leukemia (CLL)[1][2]. Acalabrutinib is a click chemistry reagent, itcontains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

DESCRIPTION Acalabrutinib is currently indicated for the treatment of adult patients with Mantle Cell Lymphoma (MCL) who have received at least one prior therapy (PKIDB)
DESCRIPTION Acalabrutinib is an orally available inhibitor of Bruton's tyrosine kinase (BTK) with potential antineoplastic activity. It prevents the activation of the B-cell antigen receptor (BCR) signaling pathway. It also plays an important role in B lymphocyte development, activation, signaling, proliferation and survival. (Enamine Bioactive Compounds)
DESCRIPTION Acalabrutinib (ACP-196), also known as ACP-196, is an orally available inhibitor of Bruton's tyrosine kinase (BTK) with potential antineoplastic activity. Upon administration, ACP-196 inhibits the activity of BTK and prevents the activation of the B-cell antigen receptor (BCR) signaling pathway. This prevents both B-cell activation and BTK-mediated activation of downstream survival pathways. This leads to an inhibition of the growth of malignant B cells that overexpress BTK. BTK, a member of the src-related BTK/Tec family of cytoplasmic tyrosine kinases, is overexpressed in B-cell malignancies; it plays an important role in B lymphocyte development, activation, signaling, proliferation and survival.
