ksd-101 therapy for ebv-associated lymphomas: an exploratory clinical trial

Conditions: EBV-associated Lymphomas

Summary: 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.
