Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Epcoritamab
Treatment: Drugs - Epcoritamab, lenalidomide and rituximab

Experimental: Arm A - EPCORITAMAB (EPCOR-ONLY)

Experimental: Arm B - EPCORITAMAB, LENALIDOMIDE AND RITUXIMAB (EPCOR-R2)


Treatment: Drugs: Epcoritamab
Epcoritamab will be administered as a 28-day cycle. In Cycle 1 and 2, epcoritamab will be given with step up dosing in Cycle 1. From Cycle 3 onwards dosing will be on Day 1 and 15 of each cycle.

Treatment: Drugs: Epcoritamab, lenalidomide and rituximab
Treatment with epcoritamab will be administered following the same dosing schedule as Arm A. On days where rituximab and/or lenalidomide are also due, epcoritamab should be administered last.

Patients will receive lenalidomide once daily on Day 1-21 of each 28-day cycle, starting at Cycle 1 through to Cycle 6.

Patients will receive rituximab administered by intravenous (IV) infusion on Day 1, 8, 15 and 22 of Cycle 1 and on Day 1 only of Cycles 2-6.

7. Adequate haematological function documented within 7 days prior to randomisation
8. Adequate cardiac function.
9. Adequate renal function, documented within 7 days prior to randomisation
