"The initial dose is 80mg/day. If the treatment is ineffective after 4 weeks, and under the condition of good safety, the investigator will judge that the dosage should be added to 80mg twice/day，or a higher dose for oral maintenance. The maximum dose is 160mg twice a day. The duration of zanubrutinib is 24 weeks.~In case of intolerable adverse reactions, such as severe infection, severe bleeding, hematopenia, arrhythmia, etc., investigator can reduce the dose of zanubrutinib, or withdraw from clinical trials as appropriate."
