简要总结
This study aimed to investigate the efficacy and safety of DEP (liposomal doxorubicin, etoposide and methylprednisolone) together with PD-1 antibody as an treatment for EBV associated hemophagocytic lymphohistiocytosis.
详细描述
PD-1 antibody added to the DEP regimen （with or without asparaginases） in EBV-HLH,

研究组 & 干预措施
DEP combine with PD-1 antibody
doxorubicin (doxorubicin hydrochloride liposome injection) 25 mg/m2 day 1; etoposide 100 mg/m2 was administered day1; methylprednisolone 1.5mg/kg days 1 to 3,then 0.25mg/kg day 4 to 14; sintilimab injection 200mg day 4. This regimen was repeated after 2 weeks.
干预措施: DEP combine with PD-1 antibody (Drug)
结局指标
主要结局
Evaluation of treatment response
时间窗: Change from before and 2,4,6 and 8 weeks after initiating DEP combine with PD-1 antibody therapy
The primary observed endpoint is the objective remission rate (ORR): cases that include complete remission (CR) and partial remission (PR).CR was defined as normalization of all of the quantifiable symptoms and laboratory markers of HLH, including levels of sCD25, ferritin, and triglyceride; hemoglobin; neutrophil counts; platelet counts; and alanine aminotransferase (ALT). PR was defined as at least a 25% improvement in 2 or more quantifiable symptoms and laboratory markers as follows: sCD25 response was\>1.5-fold decreased; ferritin and triglyceride decreased at least 25%; for patients with an initial neutrophil count of\<0.5 ×109/L, a response was defined as an increase by at least 100% to\>0.5× 109/L; for patients with a neutrophil count of 0.5 to 2.0 × 109/L, an increase by at least 100% to \>2.0 × 109/L was considered a response; and for patients with ALT \>400 U/L, response was defined as an ALT decrease of at least 50%.
次要结局
- EBV-DNA(Change from before and 2,4,6 and 8 weeks after initiating DEP combine with PD-1 antibody therapy)
- Survival(3 months after the intervention)
- Adverse events that are related to treatment(2,4,6 and 8 weeks after initiating DEP combine with PD-1 antibody therapy)
