General

The most common adverse reactions in patients with B-cell malignancies were thrombocytopenia, diarrhea, fatigue, musculoskeletal pain, neutropenia, rash, anemia, bruising, nausea, hemorrhage, arthralgia, and upper respiratory tract infection.

The most common adverse reactions in patients with chronic graft-versus-host disease were fatigue, anemia, bruising, diarrhea, thrombocytopenia, musculoskeletal pain, pyrexia, muscle spasms, stomatitis, hemorrhage, nausea, abdominal pain, pneumonia, and headache.[Ref]

Cardiovascular

Hypertension occurred in 19% of 1476 patients with B-cell malignancies who received this drug in clinical trials; grade 3 or greater hypertension occurred in 8% of patients. Based on data from a subset of these patients (N=1124), the median time to onset was 5.9 months (range: 0 to 24 months). In a long-term safety analysis over 5 years of 1284 patients with B-cell malignancies treated for a median of 36 months (range: 0 to 98 months), the cumulative rate of hypertension increased over time. The prevalence for grade 3 or greater hypertension was 4% (year 0 to 1), 7% (year 1 to 2), 9% (year 2 to 3), 9% (year 3 to 4), and 9% (year 4 to 5); the overall incidence for the 5-year period was 11%.

Fatal and serious cardiac arrhythmias and cardiac failure have occurred with this drug. Deaths due to cardiac causes or sudden deaths occurred in 1% of 4896 patients who received this drug in clinical trials, including in those who received this drug in unapproved monotherapy or combination regimens. These adverse reactions occurred in patients with and without preexisting hypertension or cardiac comorbidities.

Grade 3 or greater ventricular tachyarrhythmias were reported in 0.2%, grade 3 or greater atrial fibrillation and atrial flutter were reported in 3.7%, and grade 3 or greater cardiac failure was reported in 1.3% of 4896 patients who received this drug in clinical trials, including in those who received this drug in unapproved monotherapy or combination regimens, and especially in patients with acute infections or cardiac risk factors (including hypertension, diabetes mellitus, history of cardiac arrhythmias).

Dermatologic

Gastrointestinal

Genitourinary

Hematologic

Fatal bleeding events have occurred in patients who received this drug. Major hemorrhage (grade 3 or greater, serious, or any central nervous system events, e.g., intracranial hemorrhage [including subdural hematoma], gastrointestinal bleeding, hematuria, and postprocedural hemorrhage) occurred in 4.2% of patients, with fatalities occurring in 0.4% of 2838 patients who received this drug in 27 clinical trials. Bleeding events (any grade) including bruising and petechiae occurred in 39% and excluding bruising and petechiae occurred in 23% of patients who received this drug, respectively.

Across clinical trials, 3.1% of 2838 patients who received this drug without antiplatelet or anticoagulant therapy experienced major hemorrhage. The addition of antiplatelet therapy (with or without anticoagulant therapy) increased the incidence to 4.4%, and the addition of anticoagulant therapy (with or without antiplatelet therapy) increased the incidence to 6.1%.

In 645 patients with B-cell malignancies who received this drug as a single agent, grade 3 or 4 neutropenia occurred in 23% of patients, grade 3 or 4 thrombocytopenia in 8% of patients, and grade 3 or 4 anemia in 2.8% of patients, based on laboratory measurements.

Immunologic

Metabolic

Musculoskeletal

Nervous system

Other malignancies (10%), including nonskin carcinomas (3.9%), occurred among the 1476 patients with B-cell malignancies who received this drug in clinical trials. The most frequent second primary malignancy was nonmelanoma skin cancer (6%).
