Inclusion Criteria
1. 18-75 Years old (include 18 and 75), gender is not limited.
2. Measurable lesions by computed tomography (CT)/magnetic resonance imaging (MRI). A
measurable lesion is defined as follows: at least the longest diameter of one lymph
node >1.5cm and clearly measurable in two vertical directions, or at least the longest
diameter of one extranodal lesion >1cm (e.g., liver nodule); If only spleen or
gastrointestinal mucosa is involved, corresponding examinations and evaluations will
be conducted in the investigator's opinion.
3. The diagnosis report must contain morphology and evidence of positive cyclin D1 by
immunohistochemistry or evidence of t (11; 14). The above results are tested by
immunohistochemistry, cytogenetics or Fluorescent in situ hybridization (FISH). After
enrollment, tumor tissue (FFPE) blocks or sections must be sent to the central
laboratory for confirmation of MCL.
4. The laboratory parameters are as follows:
1. Hematology: Neutrophils = 1.0×10^9/L without growth factor or blood transfusion,
platelets = 75×10^9L (=50×10^9/L if bone marrow is involved), and hemoglobins >
9g/dL within 7 days before enrollment into the study.
2. Liver: Aspartate aminotransferase (AST)/serum glutamic oxaloacetic transaminase
(SGOT) and alanine aminotransferase (ALT)/serum glutamic pyruvic transaminase
(SGPT) = 2.5×ULN; total bilirubin = 2×ULN (< 3×ULN when diagnosed as Gilbert's
syndrome).
3. Kidney: Creatinine clearance=30 ml/min (Evaluated by estimated glomerular
filtration rate [eGFR] according to the Cockcroft-Gault Equation or the
calculation equation of each site); Cockcroft-Gault equation= Female:
(140-age)×weight(kg)×0.85/(72×serum creatinine (mg/dL)) Male: (140-age)×body
weight(kg)/(72×serum creatinine(mg/dL))
4. international normalized ratio(INR) = 1.5×ULN and activated partial
thromboplastin time (APTT) = 1.5×ULN, and for patients with acquired hemophilia
or those treated with clotting factor inhibitors or vitamin K antagonists, the
enrollment will be determined after discussion with the investigator.
5. ECOG performance status score 0-2.
6. Life expectancy > 3 months.
7. There must be documentations on relapsed or refractory lymphoma or disease progression
after systemic therapy and at least one but less than five therapies for mantle cell
lymphoma were administrated previously (1 = number of previous therapies < 5).
8. No response with the last therapy (SD or PD during the treatment), or PD after the
therapy.
9. Patients with disease recurrence at least 3 months after autologous hematopoietic stem
cell transplantation can be enrolled into the study, if there isn't any relevant
active infection.
10. Females of child-bearing potential must agree to use highly effective contraception
methods during the study and at least 180 days after the last dose of the
investigational drug. Highly effective contraception methods include abstinence,
hysterectomy, bilateral ovariectomy without menstruation for six consecutive months,
intrauterine contraception systems, hormonal contraception such as injectable
contraceptives and oral contraceptives. Males must be sterilized via either vasectomy,
or use barrier methods, while their female partners should take the effective
contraception methods mentioned above.
11. Patients are voluntary to sign the informed consent form and can understand and comply
with all study requirements.
Exclusion Criteria
1. Patients suffering from or previously suffering from CNS lymphoma.
2. Patients received other BTK inhibitors prior to enrollment. Patients who received
steroid anti-tumor therapy (a dose equivalent to>20mg/day of prednisone) within 7
days, or received chemotherapy, targeted therapy, or radiotherapy within 4 weeks, or
received anti-tumor Chinese medicinal herbs or antibody therapy within 4 weeks, prior
to first administration of DTRMWXHS-12 capsule.
3. Patients received major surgery in the past 4 weeks before screening (determined by
the investigator according to the patient's condition).
4. Patients with active bleeding or combination with anticoagulant therapy within 3-6
months.
5. Patients had undergone chemotherapy before and in whom the toxicity has not resolved
(the toxicity has not resolved to = grade 1 as per National Cancer Institute's Common
Terminology Criteria for Adverse Events (CTCAE) Version 4.03, except for hair loss,
absolute neutrophil count (ANC) and platelets). For neutrophils and platelets, please
refer to the criterion 4 [Neutrophils] and [Platelets] in the inclusion criteria.
6. Patients with a history of other active malignant diseases within 2 years prior to
enrollment into the study, excluding the following: (1) adequately treated cervical
carcinoma in situ; (2) local skin basal cell carcinoma or squamous cell carcinoma; (3)
malignant diseases that has been controlled and completely locally treated (by surgery
or other means)
7. Patients suffering from active cardiovascular diseases with clinical significance,
such as uncontrolled arrhythmia, congestive heart failure, Grade 3 or 4 heart disease
according to New York Heart Association (NYHA) Functional Classification, or those
with history of myocardial infarction within 6 months before screening.
8. QTcF>450 msecs or other significant ECG abnormalities, including second-degree
atrioventricular block type ?, third-degree atrioventricular block.
9. Patients who can't swallow capsules or with diseases significantly affect the
gastrointestinal function, such as malabsorption syndrome, gastric or intestinal
resection, symptomatic inflammatory bowel disease, or partial or complete intestinal
obstruction.
10. Uncontrolled systemic infections or infections requiring to be treated with
intravenous antibacterial agents.
11. Patients who previously received allogeneic stem cell transplantation.
12. Patients known to have been infected with human immunodeficiency virus (HIV) or active
hepatitis B or hepatitis C virus (polymerase chain reaction [PCR] or reverse
transcription- polymerase chain reaction (RT-PCR) shows positive results).
13. Hepatitis B test includes HBsAg, HBcAb and HBsAb. If the patient is HBsAg-negative but
HBcAb-positive (regardless of HBsAb), the PCR technology will be used to detect
hepatitis B virus (HBV) DNA, and the acceptable upper limit of normal in the table
below is 1000 IU/mL. Considering different PCR kits may be used by different sites,
the acceptable upper limit of normal for HBV DNA should be the normal value in the
site. Hepatitis C test includes hepatitis C virus (HCV) antibody test, and if the HCV
antibody is positive, the RT-PCR technology will be used to detect HCV RNA.
14. Pregnant or lactating women.
15. Any life-threatening disease, medical condition, or organ system dysfunction that, in
the investigator's opinion, may affect subject safety or lead to study risks.
16. Patients with poor compliance.
17. Patients who receive treatment with a potent CYP3A (cytochrome P450, family 3,
subfamily A) inhibitor or a potent CYP3A inducer within 7 days prior to enrollment.
