Exclusion Criteria:

• Current central nervous system involvement or suspected patients and those with a history of this condition
• Previously received systemic treatment for MCL, including BTKi.
• Uncontrolled active systemic fungal, bacterial, or viral infections (defined as persistent signs/symptoms related to the infection despite the use of appropriate antibiotics, antiviral therapy, and/or other treatments with no improvement).

  2. Subjects with positive hepatitis C antibodies must have an HCV-RNA negative result before the first dose. Subjects with positive hepatitis C PCR results will not be eligible for this study.

• Clinically severe cardiovascular diseases, including:

  1. Myocardial infarction occurring within the 6 months prior to screening;
  2. Unstable angina occurring within 3 months prior to screening;
  3. Clinically significant arrhythmias (e.g., sustained ventricular tachycardia, ventricular fibrillation, torsades de pointes ventricular tachycardia);

  6. III or IV congestive heart failure as defined by the New York Heart Association (NYHA)
• History of severe hemorrhagic disorders, such as hemophilia A, hemophilia B, von Willebrand disease, or a history of spontaneous bleeding requiring blood transfusion or other medical interventions.
• History of deep vein thrombosis (DVT) or pulmonary embolism (PE) in the past 12 months
• History of significant cerebrovascular disease/events within 6 months prior to the first administration of the investigational drug, including stroke or intracranial hemorrhage.
• Unable to swallow capsules or having significant gastrointestinal functional disorders, such as malabsorption syndrome, gastric or small intestine resection, symptomatic inflammatory bowel disease, or partial or complete intestinal obstruction.

If the patient has taken strong or moderate CYP3A inhibitors or inducers within 7 days prior to the first dose of the investigational drug (or has taken these drugs for less than 5 half-lives), they cannot be enrolled. Patients using moderate CYP3A inhibitors can be considered for the study after at least a 7-day washout period.

• Pregnant or breastfeeding women
• Hypersensitivity to any investigational drug
• Any mental or cognitive impairment that may limit their understanding, execution, and compliance with the informed consent form and the study.
• Subjects with drug abuse and alcoholism
