Indications for Ibrutinib

Chronic Lymphocytic Leukemia (CLL)/Small Lymphocytic Lymphoma (SLL) in adult patients.

Chronic Lymphocytic Leukemia (CLL)/Small Lymphocytic Lymphoma (SLL) with 17p deletion in adult patients.

Waldenström's Macroglobulinemia (WM) in adult patients.

Chronic Graft-Versus-Host Disease (cGVHD) in adult and pediatric patients aged 1 year and older after failure of one or more systemic therapies.

Administration Method for Ibrutinib

Ibrutinib is administered orally, once daily.

Precautions for Ibrutinib

Hemorrhage; Infections; Cardiac arrhythmias, heart failure, and sudden death; Hypertension; Cytopenias; Second primary malignancies; Tumor Lysis Syndrome (TLS); and Embryo-fetal toxicity.
