E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective is to determine if the efficacy of polatuzumab vedotin, rituximab, gemcitabine and prednisolone (POLA-R-GCP) or polatuzumab vedotin, rituximab, doxorubicin, cyclophosphamide and prednisolone (POLA-R-mini-CHP) is sufficient for further investigation in patients not fit for full dose R-CHOP chemo-immunotherapy. |
|
E.2.2 | Secondary objectives of the trial |
The secondary research objective is to assess the safety and tolerability of POLA-R-GCP or POLA-R-mini-CHP through an analysis of the frequency of adverse events (AEs) and the number of patients who discontinue therapy due to toxicity. |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary outcome is the 12-month Progression Free Survival rate which is measured as a binary covariate. Progression-free survival is defined as disease progression or recurrence, or death from any cause, (defined as days from the date of cohort assignment to event)as assessed by the investigator using the revised Lugano response criteria for malignant lymphoma (2016). |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Occurring within 12 months (from the date of cohort assignment). |
|
E.5.2 | Secondary end point(s) |
a. Toxicity: The frequency of Grade 3-4 adverse events (AEs) - Grade 3-4 toxicities occurring anytime from the start of treatment until 12 months following the last dose of treatment. Adverse events/Toxicities will be assessed according to standard National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) Version 4.0 following each cycle of treatment and at each subsequent follow-up visit until 12 months after the last dose of treatment. b. The number of patients completing the 6 planned courses of therapy in each cohort c. Investigator assessed end-of-treatment FDG-PET Response as assessed by a PET/CT scan performed at the end of treatment using the revised Lugano response criteria for malignant lymphoma (2016). d. Overall survival measured as the time from recruitment until death by any cause e. Time to next treatment f. Quality of life g. Co-morbidity/Frailty assessment pre- and post-treatment (excluding haematological co-morbidities) |
