Description of intervention(s) / exposure
Treatment: Drugs - Epcoritamab

Experimental: Epcoritamab Treatment - Single arm study - All patients undergo same treatment with Epcoritamab for salvage and consolidation phases.


Treatment: Drugs: Epcoritamab
Epcoritamab (Epcor) is a bispecific antibody recognizing the T-cell antigen CD3 and the B-cell antigen CD20. Epcor is a supplied as a concentrate for solution for intended subcutaneous injection. The dose must be prepared by a qualified pharmacist using aseptic technique.

Epcoritamab-Salvage treatment phase:

2-3 cycles of R-DHAOx therapy (rituximab, dexamethasone, cytarabine, oxaliplatin), given every 21 days combined with Epcoritamab subcutaneous weekly dosing (priming 0.16mg Cycle 1 Day 1, intermediate 0.8mg cycle 1 day 8, full dose 48mg from cycle 1 day 15 onwards)

Epcoritamab Consolidation phase:

6 cycles (28 days each) of subcutaneous Epcoritamab, commencing between 6-12 weeks post ASCT.

Epcoritamab dosing and timing for consolidation:

* Cycle 1 Day 1: Priming (0.16mg) dose
* Cycle 1 Day 8: intermediate (0.8mg) dose
* Cycle 1 Day 15: full dose 48mg
* Cycle 1 Day 22, Cycle 2-3 Days 1, 8, 15 and 22: 48mg
* Cycles 4 to 6 - Days 1 and 15 (fortnightly dosing): 48mg
