Eligibility

Inclusion Criteria:

• Age=18 years, gender is not limited. Patients are voluntary to sign the informed consent form.

• B-Cell Lymphoma based on WHO classified definition: including chronic lymphocytic leukemia (CLL)/ small lymphocytic lymphoma (SLL); chronic lymphocytic leukemia with 17p-; mantle cell lymphoma (MCL); Waldenstrom's macroglobulinemia(WM); Diffuse large B-cell lymphoma (DLBL or DLBCL) etc.

• Measurable lesion: non-Hodgkin 's lymphoma requires at least a two-dimensional lesion diameter = 2 cm, chronic lymphocytic leukemia = 5000 leukemia cells / mm3, Waldenstrom's macroglobulinemia IgM = 1000 mg / dL, bone marrow lymph plasma -like cells infiltration, Histopathologically diagnosed as Diffuse Large B- Cell Lymphoma.

• Investigator judges that the treatment is needed.

• Patients, who at least failed in lymphoma treatment once and without standard therapeutic options, can't satisfy the requirement or decline treatment or failed in autologous stem cell transplantation for Diffuse Large B- Cell Lymphoma.

• ECOG (Eastern Cooperative Oncology Group) performance status 0 ~1

• Life expectancy greater than 4 months

• Ability to swallow capsules

• Hematologic functions satisfy: Neutrophils =1.5×109 / L ( according to the investigators' opinion , if they judge that the patients' neutrophil count lower than this threshold, which caused by chronic lymphocytic leukemia and bone marrow infiltration, those patients are eligible to be included. ), platelet(PLT) =75×109/L, HB=80g/L

• Renal functions satisfy: Creatinine (Cr) = 1.5 times of upper limit of normal persons; creatinine clearance rate=50ml/min (estimated by Cockcroft-Gault formula or detected by nuclear medicine scan or 24 hours urine method)

• Liver functions satisfy: AST and ALT=2.5 times of normal value, bilirubin =1.5 times of normal value

• Coagulation function: international normalized ratio (INR) and APTT = 1.5 times of normal value;

• Throughout the course of the study and 90 days of treatment interruption, female of childbearing age and fertile males who must take one of the following effective contraception measures: abstinence, barrier-type dual contraceptive methods, IUDs, administration of hormonal contraception drug.

• Male subjects are prohibited sperm donation from the start to the end of treatment within 90 days.

Exclusion Criteria:

• Patients with brain metastasis

• Disease with changes of pathological tissue types (including large cell transformation)

• Patients who received allogeneic stem cell transplantation within 6 months, or with organized incompatibility reaction (GVHD), requires immunosuppressive therapy

• Patients who received steroid anti-tumor therapy within 7 days, or receive chemotherapy within 2 weeks, or receive monoclonal antibody therapy within 4 weeks, prior to first administration of DTRMWXHS-12 capsule.

• Patients received other BTK inhibitor therapy

• Patients had early received chemotherapy but their toxicity has not been cleared (according to NCI-CTCAE 4.03, unrecovered toxicity grade =1)

• Patients who received Chinese herbal anti-tumor therapy within 1 week before the start of study

• Patient with a history of other malignant within 2 years before enrollment, except (1) adequately treated in situ cervical cancer;(2) Local basal cell carcinoma or squamous cell carcinoma (3) Local malignant tumor which has been completely treated (by surgery or other means)

• Patients with uncontrolled systemic infection requiring intravenous anti-infection treatment

• Patients received major surgery in the past 4 weeks

• Patients with HIV infection, HBs-Ag positive
