Study & Design

• Study Type: INTERVENTIONAL
• Study Design: SINGLE_GROUP

Primary Outcome Measures

Name	Time	Method
Complete response rate （CRR）	At the end of Cycle 2 (each cycle is 21 days)	Complete response rate at the end of induction

Secondary Outcome Measures

Name	Time	Method
Duration of response (DOR)	From the date when criteria for response are met (CR or PR) until the date of progression or relapse. Patients without relapse or progression or death from other causes will be censored at their last assessment date (24 months from response date)
Overall Survival (OS)	Time between the date of enrolment and the date of death from any cause (12,24, 36 and 48 months)
Overall Response (CR+PR) Rate （ORR）	At the end of Cycle 2 (each cycle is 21 days)	Overall Response (CR+PR) rate at the end of induction
Progression-free survival (PFS)	Time between the date of enrolment and the date of disease progression, relapse or death from any cause (12,24 months)
Event Free Survival (EFS)	From the date of enrolment to the date of disease progression, relapse from CR, initiation of subsequent systemic anti-lymphoma therapy after the least 6 cycles of RI-CHOP (each cycle is 21 days), or death whichever occurs first (24, 36 and 48 months)
