CR-CHOP+X in Previously Untreated DEL

Официальное название

A Prospective, Open-label Phase II Study of Chidamide Plus R-CHOP + X in Previously Untreated Diffuse Large B-cell Lymphoma with Double Expression of MYC and BCL2.

Обзор

This is a prospective, single-arm, open-label phase II clinical trial that evaluates the efficacy and safety of CR-CHOP regimen combined with different targeted drugs based on different molecular subtypes in newly diagnosed DEL patients.

Подробное описание

Participants who met the inclusion/exclusion criteria signed informed consent and received 1 course of CR-CHOP, followed by stratification of the remaining 5 cycles based on genetic subtypes. C1 plus PD1 inhibitor; C2 and C3 were treated with orelabrutinib. TP53mut plus decitabine. During chemotherapy, routine evaluation was performed after each course of treatment, and an objective comprehensive evaluation of efficacy was performed after 3 courses of treatment. Efficacy evaluation Patients with CR or PR should continue the original treatment, and patients with SD or PD should be recommended second-line salvage treatment. For the first summary evaluation after completion of all treatments, CR patients are placed on chidamide maintenance therapy (2 years recommended unless intolerable toxicity or disease progression occurs).

• 3\. Age ≥ 18 years old, ≦75 years old;
• 4\. ECOG physical status score of 0, 1 or 2;
• 5\. No previous history of malignant tumors; No other tumors occurred simultaneously;
• 6\. Patients judged by the investigator to have a life expectancy of at least 6 months;
• 7\. The patient or his legal representative must provide written informed consent prior to any research special examination or procedure;
• 8\. International prognostic Index (IPI) >1 score.

Критерии исключения

• 2\. Previously received autologous stem cell transplantation;
• 3\. Previous history of other malignant tumors, except skin basal cell carcinoma and cervical carcinoma in situ;
• 4\. Accompanied by uncontrolled cardiovascular and cerebrovascular diseases, coagulation disorders, connective tissue diseases, serious infectious diseases and other diseases;
• 5\. Primary central nervous system lymphoma;
• 6\. Left ventricular ejection fraction ≤ 50%;
• 7\. Laboratory test values at the time of screening (unless due to lymphoma): A. Neutrophils <1.5\*109/L; B. Platelet <75\*109/L; C. ALT or AST were 2 times higher than the upper limit of normal, AKP and bilirubin were 1.5 times higher than the upper limit of normal; D. Creatinine levels higher than 1.5 times the upper limit of normal;
• 8\. Other concurrent and uncontrolled medical conditions that the investigator believes will affect patient participation in the study;

If the result is positive, the treatment should also be negative before admission.
