Bendamustine Plus Brentuximab Vedotin in HL and CD30+ PTCL in First Salvage Setting (FIL-BBV)

A Phase II Study With Bendamustine Plus Brentuximab Vedotin in Hodgkin's Lymphoma and CD30+ Peripheral T-cell Lymphoma in First Salvage Setting: the BBV Regimen.

This is a single-arm, open-label, multicenter, phase 2 clinical trial aimed at evaluating the efficacy and safety of the combination of bendamustine and brentuximab vedotin as a first salvage therapy in patients with relapsed or refractory Hodgkin's lymphoma or PTCL.

A total of 25 patients with PTCL, and 40 with Hodgkin's lymphoma are expected to be treated according to this treatment protocol.

Study Overview

• Status: Terminated
• Conditions: Lymphatic Diseases
• Intervention / Treatment: Drug: Brentuximab Vedotin; Drug: Bendamustine

Detailed Description

In the study, intravenous bendamustine will be administered at a dose of 90 mg/m2 on day 1 and 2 and brentuximab will be given intravenously at a total dose of 1.8 mg/kg on day 1 of each 21 days-based cycle, for 6 cycles. All patients achieving a CR can be considered eligible to peripheral blood stem cell mobilization (to be performed with granulocytecolony stimulating factor alone) and may proceed to an ASCT at any time after cycle 4.
