A Risk Stratified Sequential Treatment With Rituximab, Brentuximab Vedotin and Bendamustine (RBvB)
A Phase II Multicenter Open Label Risk Stratified Sequential Treatment With Rituximab, Brentuximab Vedotin and Bendamustine (RBvB) in Patients Newly Diagnosed.
This is an open label, risk-stratified, sequential treatment, phase 2 study of newly diagnosed post-transplant lymphoproliferative disorders with positive CD20 and CD30 expression. It includes an induction phase with rituximab and brentuximab vedotin (RBv), followed by a treatment phase with RBv or RBv in combination with bendamustine (RBvB) based on response to induction.
The primary end point is treatment efficacy measured as the overall response rate (ORR) and progression free survival (PFS).

Detailed Description
Post-Transplant Lymphoproliferative Disorders (PTLD) are defined by the revised 2017 edition of the WHO Classification of Tumours of Haematopoietic and Lymphoid Tissues as "lymphoid or plasmacytic proliferations that develop as a consequence of immunosuppression in a recipient of a solid organ, bone marrow or stem cell allograft". Within this definition 4 distinct categories exist, including: (1) Non-destructive PTLDs (plasmacytic hyperplasia, infectious mononucleosis, and florid follicular hyperplasia) (2) Polymorphic PTLD; (3) Monomorphic PTLD and (4) Classical Hodgkin Lymphoma type PTLD.
The incidence of PTLD varies between different transplanted organs. Across all transplants monomorphic PTLD is the most common accounting for 75% of all cases. Lymphoma derived of B- cell origin account for the majority of cases (70%), while T-cell neoplasms represent a small minority (5%). Within monomorphic PTLD 50% of cases demonstrate association with the Epstein Barr Virus (EBV). Polymorphic PTLD accounts for 15-20% of all PTLD cases with the majority demonstrating EBV involvement. Early lesions account for 5% of PTLD and are all uniformly associated with EBV as are all the cases of Classic Hodgkin Lymphoma type PTLD.
The current understanding of the pathogenesis of PTLD is incomplete. Despite concerted efforts, the investigators are unable to predict who will develop PTLD and do not understand why only 1 - 2% of all transplant recipients develop these disorders.

Arms and Interventions
Participant Group / ArmParticipant Group / Arm |
Intervention / TreatmentIntervention / Treatment |
|---|---|
|
Active Comparator: Low Risk
Low risk patients (those in complete response (CR) after induction) will receive rituximab (375mg/m2) and brentuximab vedotin (1.8mg/m2) on day 1 of 21 day cycles, for 4 cycles.
|
Rituximab is dosed at 375mg/m2 as an intravenous infusion.
No adjustments are necessary for hepatic or renal impairment.
Dosing will be done on baseline weight and height, however in patients who experience a >10% change in weight dosing will be readjusted.
Other Names:
Brentuximab vedotin is to be given as intravenous infusion at a dose of 1.2mg/kg during induction and 1.8mg/kg with each cycle.
Dose reductions to 1.2mg/kg are allowed at investigator discretion.
Other Names:
|
|
Active Comparator: High Risk
High risk patients (those who do not achieve a CR after induction), will receive rituximab (375mg/m2) and brentuximab vedotin (1.8mg/m2) on day 1 and bendamustine (90mg/m2) on day 1-2 of 21 day cycles for up to 8 cycles.
Interim imaging will be performed in cycle 4 (days 14-21) and patients achieving CR will receive additional 2 cycles for a total of 6, patients achieving partial response (PR) will receive 4 additional cycles.
