ECIs, events of clinical interest; UTI, urinary tract infection.
ECIs were based on combined AE terms for infections, bleeding events, hypertension, and second primary malignancies, excluding nonmelanoma skin and on a single AE term for atrial fibrillation.
Other cardiac events occurring in >1 patient included tachycardia (n = 8; all grade 1), sinus tachycardia (n = 3; all grade 1), palpitations (n = 3 [grade 1, n = 2; grade 2, n = 1]), and angina pectoris (n = 2; both grade 2).
Age range: 68 to 79 y.
Most common bleeding events (all grade, ≥15%) were contusion (42%), petechiae (18%), and ecchymosis (16%).
Includes 1 grade 1 AE (retinal hemorrhage) and 3 grade 3 AEs (hematuria, traumatic intracranial hemorrhage, and upper gastrointestinal hemorrhage).
Most common infections (all grade, ≥15%) were upper respiratory tract infections (44%) and sinusitis (21%); among patients with opportunistic infections, grade 2 fungal infection, grade 2 coccidioidomycosis, and grade 2 herpes zoster were reported in 1 patient each, and 1 patient experienced both grade 3 perineal infection fungal and grade 3 herpes zoster.
Acalabrutinib dosing was delayed in 10 patients because of infection AEs; 2 patients discontinued acalabrutinib because of grade 3 UTI and grade 4 sepsis.
