5. The level of organ function must meet the following requirements:
Bone marrow:
1. Absolute neutrophil count (ANC) ≥ 1000 /μL (if recent bone marrow biopsies or smears
prove tumor progression, this index can be < 1000/μL).
2. Hemoglobin (HGB) ≥ 9g/dL.
3. Platelet count (PLT) ≥ 1000000/μL (if recent bone marrow biopsies or smears prove

Liver function:
In patients with serum bilirubin ≤ 1.5 ×upper limit of normal value (ULN) or Gilbert
syndrome, the total bilirubin is less than 3.0 × ULN and direct bilirubin is within the
normal range.
Serum creatinine < 1.5×ULN; Alanine aminotransferase (ALT), Aspartate aminotransferase
(AST)or Alkaline phosphatase (ALP) ≤ 2.5 ×ULN.
When there is liver metastasis, ALT, AST or ALP ≤ 5 × ULN.
6.Non-pregnant women and male and female subjects who did not consider fertility during and
after the trial, or who had preserved sperm or eggs in vitro before the trial, or
reconsidered fertility according to reproductive function 5 years after the end of the
trial.
7.After a comprehensive understanding, the subjects were willing to sign the informed
consent form.
Note 1: relapse or refractory is defined as follows:
Chronic Lymphoblastic Leukemia: subjects who are ineffective after at least 2 chemotherapy
regimens, and the subjects are not suitable or refuse to transplant. Relapse: the patient
reached Complete Response (CR) or Partial Response (PR), and Progressive Disease (PD) ≥ 6
months later. Refractory: failed treatment (without CR or PR) or PD less than 6 months
after the last chemotherapy.
Malignant Lymphoma: refractory or relapse after at least 2 chemotherapy regimens.
Multiple Myeloma: relapse or refractory is defined as relapse or disease progression after
at least 2 chemotherapy regimens (refractory occurred during the last chemotherapy or
within 60 days after the last medication).
Note 2: Malignant Lymphoma includes B-cell non-Hodgkin's lymphoma, B-cell Hodgkin's
lymphoma, diffuse large B-cell lymphoma, T-cell lymphoma and so on.
Note 3: If the subjects can provide test results to confirm the nature of the disease and
the researchers determine that the nature of the disease has not changed, there is no need
for reexamination.
Note 4: For subjects with malignant lymphoma, the lesions are measured by computed
tomography (CT) or magnetic resonance imaging (MRI) or positron emission tomography (PET) /
PET-CT. Bone marrow biopsy or smear may be performed in the evaluation of curative effect.
For subjects with multiple myeloma, it can be accepted that bone marrow biopsy or smear may
be performed during the evaluation of the curative effect.
For subjects with chronic lymphoblastic leukemia, it can be accepted that bone marrow
biopsy or smear may be performed during the evaluation of the curative effect.
