Ibrutinib is a novel oral tyrosine kinase inhibitor that irreversibly binds and inhibits tyrosine-protein kinase BTK (Bruton tyrosine kinase). BTK has been found to be important in the function of B-cell receptor signaling and therefore in the maintenance and expansion of various B-cell malignancies including chronic lymphocytic leukemia (CLL) and mantle cell lymphoma (MCL). Targeting BTK with ibrutinib has been found to be an effective strategy in treating these malignancies. Phase I clinical testing in non-Hodgkin's lymphomas and CLL showed that the drug was extremely well tolerated with no major dose-limiting toxicities and a 54% overall response rate. Subsequently, two phase Ib/II studies were performed on patients with CLL, one in relapsed/refractory CLL and one in previously untreated elderly patients with CLL. Both of these studies continued to show good tolerability of the drug and an overall response rate of about 71% with extended duration of response. Another phase II study using ibrutinib in relapsed/refractory MCL was conducted and also showed that it was well tolerated with an overall response rate of 68% and extended duration of response. Due to these results, the U.S. Food and Drug Administration granted accelerated approval for ibrutinib in November 2013 for patients with MCL who had received at least one prior therapy and in February 2014 for patients with CLL who had received at least one prior therapy. This review will discuss the preclinical pharmacology, pharmacokinetics and clinical efficacy to date of ibrutinib in the treatment of CLL and MCL.

Fatal bleeding events have occurred in patients treated with IMBRUVICA. Grade 3 or higher bleeding events (subdural hematoma, gastrointestinal bleeding, hematuria and post procedural hemorrhage) have occurred in up to 6% of patients. Bleeding events of any grade, including bruising and petechiae, occurred in approximately half of patients treated with IMBRUVICA. The mechanism for the bleeding events is not well understood. IMBRUVICA may increase the risk of hemorrhage in patients receiving antiplatelet or anticoagulant therapies. Consider the benefit-risk of withholding IMBRUVICA for at least 3 to 7 days pre and post-surgery depending upon the type of surgery and the risk of bleeding.

Ibrutinib acquired an accelerated approval for the treatment of mantle cell lymphoma who have received at least one prior therapy. 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. Ibrutinib is indicated for the treatment of chronic lymphocytic leukemia (CLL) who have at least one prior therapy. 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. Ibrutinib is indicated for the treatment of chronic lymphocytic leukemia (CLL) with 17p deletion. 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. Ibrutinib is indicated for the treatment of patients with Waldenstrom's Macroglobulinemia (WM). 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.

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. Clinical studies for relapsed/refractory CLL in phase I and II showed an approximate 71% of overall response rate.. In the case of relapsed/refractory mantle cell lymphoma, approximately 70% of the tested patients presented a partial or complete response.. 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.

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.
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.
Volume of Distribution
The volume of distribution at steady-state of ibrutinib is in approximately 10,000 L.
Clearance
In patients with normal renal function, the clearance rate is in the range of 112-159 ml/min.
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.
Since 2014, Ibrutinib has been available as a new drug for the treatment of leukemic diseases. Ibrutinib (Imbruvica) is metabolized in the liver mainly by the isoenzyme CYP3A4 and to a minor extent by CYP2D6. Simultaneous application of Imbruvica and consumption of foods containing secondary metabolites strongly inhibiting the CYP3A4 isoform, could significantly influence the toxicity of this drug. This article references the respective foods.

The elimination half-life of ibrutinib is of approximately 4-6 hours.
Ibrutinib is an inhibitor of Brutons 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-.

... In this study we report for the first time that ibrutinib is cytotoxic to malignant plasma cells from patients with multiple myeloma (MM) and furthermore that treatment with ibrutinib significantly augments the cytotoxic activity of bortezomib and lenalidomide chemotherapies. We describe that the cytotoxicity of ibrutinib in MM is mediated via an inhibitory effect on the nuclear factor-(k)B (NF-(k)B) pathway. Specifically, ibrutinib blocks the phosphorylation of serine-536 of the p65 subunit of NF-(k)B, preventing its nuclear translocation, resulting in down-regulation of anti-apoptotic proteins Bcl-xL, FLIP(L) and survivin and culminating in caspase-mediated apoptosis within the malignant plasma cells....

Mantle cell lymphoma (MCL) is an aggressive B-cell malignancy that characteristically shows overexpression of cyclin-D1 due to an alteration in the t(11;14)(q13;q32) chromosomal region. Although there are some promising treatment modalities, great majority of patients with this disease remain incurable. The B-cell antigen receptor (BCR) signaling plays a crucial role in B-cell biology and lymphomagenesis. Bruton tyrosine kinase (BTK) has been identified as a key component of the BCR signaling pathway. Evidence suggests that the blockade of BTK activity by potent pharmacologic inhibitors attenuates BCR signaling and induces cell death. Notably, the expression levels and the role of BTK in MCL survival are still elusive. Here, we demonstrated a moderate to strong BTK expression in all MCL cases (n=19) compared to benign lymphoid tissues. Treatment of MCL cell lines (Mino or Jeko-1) with a potent BTK pharmacologic inhibitor, Ibrutinib, decreased phospho-BTK-Tyr(223) expression. Consistent with this observation, Ibrutinib inhibited the viability of both Mino and JeKo-1 cells in concentration- and time-dependent manners. Ibrutinib also induced a concentration-dependent apoptosis in both cell lines. Consistently, Ibrutinib treatment decreased the levels of anti-apoptotic Bcl-2, Bcl-xL, and Mcl-1 protein. These findings suggest that BTK signaling plays a critical role in MCL cell survival, and the targeting of BTK could represent a promising therapeutic modality for aggressive lymphoma.

Ibrutinib is a small-molecule inhibitor of Bruton's tyrosine kinase (BTK). Ibrutinib forms a covalent bond with a cysteine residue in the BTK active site, leading to inhibition of BTK enzymatic activity. BTK is a signaling molecule of the B-cell antigen receptor (BCR) and cytokine receptor pathways. BTK's role in signaling through the B-cell surface receptors results in activation of pathways necessary for B-cell trafficking, chemotaxis, and adhesion. Nonclinical studies show that ibrutinib inhibits malignant B-cell proliferation and survival in vivo as well as cell migration and substrate adhesion in vitro.
