Ibrutinib is a kinase inhibitor indicated for the treatment of patients:
(1) Had received at least 1 prior therapy for mantle cell lymphoma (MCL) patients;
(2) Had received at least 1 prior therapy for chronic lymphocytic leukemia (CLL).
These indications were based on the overall remission rate. Survival or disease-related symptom improvement has not been established.
MCL: 560 mg orally once daily (4 140 mg capsules once daily)
CLL: 420 mg orally once daily (3 140 mg capsules once daily)
Oral capsule with one glass of water. Do not open or chew the capsule.
(1) Bleeding: 5% of patients with MCL had grade 3 or higher bleeding events (subdural hematoma, gastrointestinal bleeding, and hematuria). In summary, bleeding events including any grade bruising occurred in 48% of patients with MCL treated with 560 mg daily. The benefit risk profile of ibrutinib needs to be considered in patients on antiplatelet or anticoagulant therapy; Ibrutinib was stopped at least 3-7 days before surgery depending on the type of surgery and bleeding risk.
(2) Infection: surveillance of patients with fever and infection and prompt evaluation.
(3) Myelosuppression: Grade 3 or 4 pancytopenia on therapy occurred in 41% of patients. These included neutropenia (29%), thrombocytopenia (17%), and anemia (9%). Complete blood counts were checked monthly.
(4) Nephrotoxicity: fatal and severe cases have occurred while on therapy with ibrutinib. Treatment emergent increases in creatinine levels to 1.5 times the upper limit of normal occurred in 67% of patients and to 1.5 to 3 times the upper limit of normal in 9% of patients. Monitor renal function and maintain hydration.
(5) Second primary malignancies: MCL patients treated with ibrutinib had previously developed other malignancies (5%), including skin cancer (4%), and other carcinomas (1%).
(6) Embryo fetal toxicity: a fetal hazard. Counsel women about the potential risks to the fetus avoid taking medicines when pregnant.
