DrugBank Accession Number

DB09053

Background

Ibrutinib is a small molecule that acts as an irreversible potent inhibitor of Burton's tyrosine kinase. It is designated as a targeted covalent drug and it presents a very promising activity in B cell malignancies.⁴ Ibrutinib was developed by Pharmacyclics Inc and in November 2013 was FDA-approved for the treatment of mantle cell lymphoma. Later, in February 2014, ibrutinib was approved for the treatment of chronic lymphocytic leukemia and it is also indicated for the treatment of patients with Waldenström's Macroglobulinemia.¹³ Ibrutinib has also been approved by the EMA for the treatment of chronic lymphocytic leukemia and mantle cell lymphoma.⁴ Ibrutinib was approved for use in chronic graft versus host disease in August 2017 ¹².

Pharmacology

Indication

Ibrutinib acquired an accelerated approval for the treatment of mantle cell lymphoma who have received at least one prior therapy.^Label Mantle cell lymphoma (MCL) is a B-cell non-Hodgkin lymphoma that develops in the outer edge of a lymph node. MCL is usually diagnosed at late stages and it is easily spread into bone marrow, spleen, liver and gastrointestinal tract.¹⁴

Ibrutinib is indicated for the treatment of chronic lymphocytic leukemia (CLL) who have at least one prior therapy.^Label CLL is a type of cancer caused by an overproduction of lymphocytes by the bone marrow. Some of the symptoms include swollen lymph nodes and tiredness.¹⁵

Ibrutinib is indicated for the treatment of chronic lymphocytic leukemia (CLL) with 17p deletion.^Label CLL with 17p is a type of leukemia in which a deletion in 17p disrupts the tumor suppressor p53 by deleting one allele of the TP53 gene. The remaining allele is mainly inactivated and thus, this type of leukemia is unresponsive to p53-dependent treatments.⁵

Ibrutinib is indicated for the treatment of patients with Waldenstrom's Macroglobulinemia (WM).^Label WM, also called lymphoplasmacytic lymphoma, is a type of non-Hodgkin lymphoma in which the cancer cells make large amounts of macroglobulin. The macroglobulin is a monoclonal protein that corresponds to the type of IgM antibodies and the unrestricted formation of this protein causes typical symptoms such as excessive bleeding and effects in vision and nervous system.¹⁶

Pharmacodynamics

In vitro studies have shown an induction of CLL cell apoptosis even in presence of prosurvival factors. It has also been reported an inhibition of CLL cell survival and proliferation as well as an impaired in cell migration and a reduction in the secretion of chemokines such as CCL3 and CCL4. The latter effect has been shown to produce regression in xenograft mouse models.⁶

Clinical studies for relapsed/refractory CLL in phase I and II showed an approximate 71% of overall response rate.^7,8. In the case of relapsed/refractory mantle cell lymphoma, approximately 70% of the tested patients presented a partial or complete response.^7,9. In clinical trials for relapsed/refractory diffuse large B-cell lymphoma, a partial response was found in between 15-20% of the patients studied; while for patients with relapsed/refractory Waldenstrom's macroglobulinemia, a partial response was observed in over 75% of the patients tested. Finally, for patients with relapsed/refractory follicular lymphoma, a partial to complete response was obtained in approximately 54% of the patients.⁷

Mechanism of action

Ibrutinib is an inhibitor of Bruton’s tyrosine kinase (BTK). It forms a covalent bond with a cysteine residue in the active site of BTK (Cys481), leading to its inhibition. The inhibition of BTK plays a role in the B-cell receptor signaling and thus, the presence of ibrutinib prevents the phosphorylation of downstream substrates such as PLC-γ.⁶

Absorption

Ibrutinib is rapidly absorbed after oral administration and it presents a Cmax, tmax and AUC of approximately 35 ng/ml, 1-2 hour and 953 mg.h/ml respectively.¹¹

Volume of distribution

The volume of distribution at steady-state of ibrutinib is in approximately 10,000 L.¹¹

Protein binding

Irreversible plasma protein binding increases gradually over time and reaches 25% of the administered dose 8 hours after initial administration. From the plasma proteins, ibrutinib has been shown to be mainly bound to albumin and to bind to α1 AGP.³ The irreversible protein binding of ibrutinib to plasma proteins can account for 97.3% of the administered dose.¹¹

Metabolism

Three metabolic pathways have been identified according to the possible metabolites. These pathways are the hydroxylation of the phenyl group (M35), the opening of the piperidine with a reduction of the primary alcohol (M34) and the oxidation to a carboxylic acid and epoxidation of the ethylene followed by a hydrolysis to the formation of dihydrodiol (PCI-45227). The latter metabolite presents also 15 times lower inhibitory activity against BTK. The metabolism of ibrutinib is mainly performed by CYP3A5 and CYP3A4. and in a minor extent it is seen to be performed by CYP2D6.³

Route of elimination

The cumulative excretion of ibrutinib in urine is of about 7.8% of the administered dose and most of this excretion is found during the first 24 hours after administration. In feces, the cumulative excretion accounts for 80% of the administered dose and the excretion occurs within 48 hours of the initial administration. The total excretion of ibrutinib during the first 168 hours after initial administration accounts for 88.5% of the administered dose.³

Half-life

The elimination half-life of ibrutinib is of approximately 4-6 hours.¹¹

Clearance

In patients with normal renal function, the clearance rate is in the range of 112-159 ml/min.³
