KSD-101 Therapy for EBV-associated Lymphomas: an Exploratory Clinical Trial

KSD-101 Therapy for EBV-associated Lymphomas: an Exploratory Clinical Trial

The main purpose of this study is to determine the tolerability and feasibility of KSD-101 in patients with EBV-associated haematologic neoplasms,to observe the characteristics of dose-limiting toxicity (DLT)and to explore the range of effective dose.

Inclusion Criteria:

1. The patient or his legal guardian participated voluntarily and signed the informed consent form.
2. A patient aged 18 - 70 years ( inclusive ) on the day of signing the informed consent form, male or female.
3. A patient who is diagnosed with EBV-associated Lymphomas，and fail to respond or relapse after conventional treatment, or voluntarily choose therapeutic DC vaccines as the salvage therapy.
4. ECOG performance score 0 - 1.
5. Meet apheresis or intravenous blood collection criteria and no other contraindications.
6. Adequate organ function:Hematology: neutrophils of ≥1×10^9 /L , hemoglobin of ≥ 70 g / L, platelets of ≥ 50 ×10^9 / L. Liver function: ALT, AST ≤ 3 × ULN and TBIL ≤ 1.5 × ULN.Renal function: creatinine ≤ 1.5 × ULN. Cardiac function: left ventricular ejection fraction LVEF ) ≥ 40%. Coagulation function: fibrinogen ≥ 1.0 g / L, activated partial thromboplastin time ( APTT ) ≤ 1.5 × ULN, prothrombin time ( PT ) ≤ 1.5 × ULN.
7. A patient who has a lymph node area where subcutaneous injection can be performed.

Exclusion Criteria:

5. Patients had an uncontrollable infectious disease within the first 4 weeks of enrollment（ except the CTCAE toxicity grade is less than 2 of genitourinary infections and upper respiratory tract infections , EBV infection）
6. A patient who has serious underlying diseases (such as cardiovascular disease, respiratory disorder, renal insufficiency, coagulation disorder, autoimmune disease or immunodeficiency disease, etc.).
7. A patient who has had other active malignancies within the last 3 years, unless curable and clearly cured, such as basal or squamous cell carcinoma, carcinoma in situ of cervix or breast, etc.
