Summary  This single‐arm, multicentre, phase I study is the first study of zanubrutinib, a potent, specific, irreversible Bruton tyrosine kinase (BTK) inhibitor, in Chinese patients with relapsed/refractory B‐cell malignancies. The objectives were to evaluate safety and preliminary anti‐tumour activity. Forty‐four patients received zanubrutinib 320 mg once daily (QD) ( n  = 10) or 160 mg twice daily (BID) ( n  = 34) until disease progression or unacceptable toxicity. 29.5% of patients received zanubrutinib for at least two years. The most common adverse event (AE) and the most common grade 3 or higher AE was neutrophil count decreased (54.5% and 25.0% respectively). Two patients (4.5%) discontinued treatment due to AEs and one treatment‐emergent AE led to death. All haemorrhagic events were grade 1–2 (except for one non‐serious grade 3 purpura). No second primary malignancies, tumour lysis syndrome, or atrial fibrillation/flutter occurred. The overall response rate was 52.3% (complete response rate, 18.2%). Patients with all cancer subtypes benefited from treatment.  BTK  C481S/R or L528W mutations were found in zanubrutinib‐progressive patients. The safety/efficacy profiles of patients treated with 320 mg QD and 160 mg BID were comparable and similar daily area under the curve (AUC) was achieved. Overall, zanubrutinib was well tolerated and either of these two regimens is clinically practical.
