Bendamustine Plus Subcutaneous Rituximab in Patients With Diffuse Large B-cell Lymphoma

NCT02753062 | Unknown Phase 2 DMC

• 1 other identifier: BR_PTLD
• Study Type: interventional
• Target: 22
• Locations: 1 country
• Sites: 1

Brief Summary

This is an open-label, multi-center, prospective, single arm phase 2 trial of the combination of bendamustine and rituximab in patients with PTLD, monomorphic cluster of differentiation antigen 20(CD20) positive DLBCL. The investigators want to investigate the efficacy and safety of the combination of bendamustine and rituximab in patients with previously untreated PTLD, monomorphic CD20 (+) diffuse large B-cell lymphoma.

Conditions

Diffuse Large B Cell Lymphoma

Outcome Measures

Primary Outcomes (1)

• complete response rate

  6 to 8 weeks after completion of the 6th cycle of treatment.

Secondary Outcomes (5)

• Assess response rate

  2 to 3 weeks (or start of next cycle) after completion of the 3rd cycle of treatment and 6 to 8 weeks after completion of the 6th cycle of treatment.

• Assess event-free survival

  the time from the 1st day of treatment to the first recording of disease-progression, relapse or death of any cause or failure to achieve CR after completion, assessed up to 96 months

• Assess overall survival

  the time from the 1st day of treatment to death of any cause or the date of last follow-up, assessed up to 96 months.

• Number of participants with treatment-related adverse events as assessed by CTCAE v4.0

  From the date of first drug administration until the date of the 28th days of last drug administration, assessed up to 22 weeks

• Assess health-related quality of life by EORTC QLQ-C30 (3rd edition)

  within 14 days prior to treatment start and every 12 months (± 1 months) of follow-up period until final analysis and at the time of disease progression, assessed up to 96 months

Study Arms (1)

bendamustine, rituximab

EXPERIMENTAL

Bendamustine plus subcutaneous Rituximab treatment of 6 cycles. Rituximab 1400mg subcutaneous over 5mins on day 1 and bendamustine 120mg/m2 + NS 500mL iv over 1hour on day 1 and 2.

Drug: bendamustine, rituximab

Interventions

bendamustine, rituximab DRUG

subjects will receive rituximab 375mg/m2 on day 1 and bendamustine 120mg/m2 by intravenous infusion on day 2 and 3 in the first cycle. From the 2nd to 6th cycle, rituximab will be administered subcutaneously at a fixed dose of 1400mg and bendamustine 120mg/m2 by intravenous infusion on day 1 following administration of rituximab and day 2.
