A Study of R-mini-MCOP in the Treatment of Elderly, Previously Untreated DLBCL

NCT06921044 | Not Yet Recruiting Phase 2

• 1 other identifier: CSPC-DED-DLBCL-K15
• Study Type: interventional
• Target: 33
• Locations: 0 countries
• Sites: N/A

Brief Summary

Research purpose： To evaluate the efficacy and safety of R-mini-MCOP in first-line treatment of primary treatment of diffuse large B-cell lymphoma (DLBCL) in elderly patients Experimental design： Single-arm, multicenter, prospective study

Conditions

Diffuse Large B-Cell Lymphoma

Keywords

Diffuse large B-cell lymphoma，; Mitoxantrone Hydrochloride liposomal

Outcome Measures

Primary Outcomes (1)

• Complete response rate （CRR）

  Complete response rate at the end of induction

  At the end of Cycle 2 (each cycle is 21 days)

Secondary Outcomes (5)

• Overall Response (CR+PR) Rate （ORR）

  At the end of Cycle 2 (each cycle is 21 days)

• 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)

• 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)

• Overall Survival (OS)

  Time between the date of enrolment and the date of death from any cause (12,24, 36 and 48 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)
