An open-label, prospective Phase III clinical study to compare polatuzumab vedotin plus rituximab, ifosfamide, carboplatin and etoposide (Pola-R-ICE) with rituximab, ifosfamide, carboplatin and etoposide (R-ICE) alone as salvage therapy in patients with primary refractory or relapsed diffuse large B-cell lymphoma (DLBCL)

Study Overview

• Status: Recruiting
• Conditions: Refractory Diffuse Large B-Cell Lymphoma; Relapsed Diffuse Large B-cell Lymphoma
• Intervention / Treatment: Drug: Polatuzumab Vedotin; Drug: Mabthera; Drug: Ifosfamide; Drug: Carboplatin; Drug: Etoposide

Detailed Description

The study is designed as an international, multicenter, open-label, two-arm, prospective phase III study to compare the treatment of polatuzumab vedotin plus rituximab, ifosfamide, carboplatin and etoposide (Pola-R-ICE) with the combination of rituximab, ifosfamide, carboplatin and etoposide (R-ICE) alone as salvage therapy in patients with primary refractory or relapsed DLBCL.

The study will involve study sites in Germany, UK, Spain, and Austria. It is planned to include 324 patients who will be randomized 1:1 to receive either treatment in the experimental arm (Pola-R-ICE) or in the standard arm (R-ICE) to end up with 308 evaluable subjects for the randomized part of the trial. Further 10 patients will be treated with Pola-R-ICE during the safety run-in phase.

The study consists of a screening/inclusion visit, three chemotherapy cycles, an end-of - treatment visit (EoT), and follow-up visits. For each subject, the total duration of the study will be approximately 3 months of treatment plus at least 21 months follow-up. The study will end when the last included patient will have passed the last follow-up visit (LPLFU). For the study as a whole, the primary outcome will be evaluated when the last included patient will have completed the 21 months follow-up period or has left the study prematurely.

For the study as a whole, the primary outcome will be evaluated when the last included patient will have completed the 21 months follow-up period or has left the study prematurely.

  (14) Ongoing treatment or study procedures within any other Investigational Medicinal Product (IMP) clinical trial with the exception of follow-up. In case of a preceding clinical trial, last application of the respective IMP(s) must have been done more than five elimination half-lives before start of study medication in this trial.
