Brief summary: Patients with newly diagnosed MCL were treated with ZR2 regimen for 3 cycles, followed by 3 cycles of immunochemotherapy, and zebrutinib maintenance therapy for 2 years after the end of induction therapy, in order to improve the remission rate and prognosis of patients with induction therapy.

Detailed description: This is a prospective, single-arm, multicenter, Phase II clinical study evaluating sequential immunochemotherapy followed by rituximab, lenalidomide, and zebutinib combined with or without autologous hematopoietic stem cell transplantation followed by zebutinib maintenance therapy for initial treatment of capsular cell lymphoma. There are three stages: screening, treatment and follow-up. The screening period was 28 days before the first administration. Treatment period: Enrolled subjects first received 3 cycles of rituximab, lenalidomide, zebutinib without chemotherapy (21 days for one cycle), followed by 3 cycles of RDHAP immunochemotherapy (21 days for one cycle); All patients were assessed with interim Positron Emission Tomography (iPET) after 3 cycles of rituximab, lenalidomide, and zebutinib without chemotherapy. All patients will continue to receive 3 cycles Of RDHAP, followed by Treatment End Of Positron Emission Tomography. For patients who have achieved complete metabolic response (CMR) or partial metabolic response (PMR), autologous hematopoietic stem cell transplantation (ASCT) can be performed as consolidation therapy after the researchers evaluate their physical status and their personal wishes. 3 months after ASCT, PET will be reviewed for efficacy evaluation after transplantation. Zebutinib maintenance therapy was started 2 months after transplantation for 2 years. For patients without ASCT, zebutinib maintenance therapy was started directly for 2 years. The follow-up period was entered after the end of maintenance therapy. Efficacy was evaluated using Lugano2014 criteria. Patients with disease progression during non-chemotherapy treatment were directly entered into RDHAP immunochemotherapy, and patients with disease progression during immunochemotherapy were directly removed from the group and entered second-line treatment. Objective effective rate, safety index and survival data of patients were observed during the experiment. Subjects will enter the follow-up period after the study treatment is discontinued or the treatment period has been completed.

Exclusion Criteria:

* The diagnosis was leukemic mantle cell lymphoma.
* Central nervous system involvement secondary to lymphoma.
* history of other active malignant diseases within 2 years prior to study entry, but eligibility for inclusion :(1) adequately treated carcinoma in situ of the cervix; (2) local basal cell carcinoma or squamous cell carcinoma of skin; (3) Pre-existing malignant disease that is under control and has undergone local radical treatment (surgical or other forms).

Screening stage of hepatitis b surface antigen or hepatitis c virus antibody positive patients, must further by hepatitis b virus DNA (no more than 1000 iu/ml) and HCV RNA detection (shall not exceed the method detection limit), in the activity of the ruled out the need for treatment after hepatitis b or hepatitis c infection, before the experiment. Patients with hepatitis B virus carriers, stabilized hepatitis B after drug treatment and cured hepatitis C can be included.

* A history of deep vein thrombosis (DVT) or pulmonary embolism (PE) within the past 12 months.
* Patients who must take antiplatelet drugs and anticoagulant drugs at the same time due to underlying diseases and have no alternative treatment plan.
* Continuous treatment with strong and moderate CYP3A inhibitors or CYP3A inducers is required. Patients were excluded if they had taken a CYP3A potent or moderate-acting inhibitor or inducer within 7 days prior to the first administration of the study drug (or had taken these drugs for less than 5 half-lives).
* Patients deemed unsuitable for the study by other investigators.
