About this trial
This study is being done to determine if epcoritamab can be used to treat participants with previously treated Waldenstrom Macroglobulinemia (WM).
The names of the study drug involved in this study is:
-Epcoritamab (a type of antibody)
Eligibility criteria
Qualifiers
A diagnosis of lymphoplasmacytic lymphoma/WM that is CD20+ by immunophenotype or immunohistochemistry confirmed by bone marrow biopsy/aspirate (fresh or archival tissue acceptable) at time of most recent progression. All degrees of CD20 positivity will be accepted.
Serum IgM level >2x upper limit of normal (ULN)
Meeting criteria for initiation of treatment per IWWM2 criteria [Kyle Semin Oncol 2002], including but not limited to hyperviscosity syndrome, peripheral neuropathy, cold agglutinin disease, cryoglobulinemia, amyloidosis, cytopenias due to bone marrow infiltration, symptomatic or bulky lymph nodes, symptomatic splenomegaly, constitutional symptoms not otherwise explained by other causes, signs of organ dysfunction secondary to WM
At least one prior line of treatment that was discontinued either due to intolerance or disease progression
Disqualifiers
Participants who have disease that has transformed to aggressive lymphoma
Participants with symptomatic or suspected hyperviscosity syndrome or IgM levels greater than 4000 mg/dL who are unable to undergo plasmapheresis to decrease the risk of an IgM flare. Participants who can undergo plasmapheresis will be eligible as long as they undergo the procedure prior to first treatment dose.
Participants who are receiving any other investigational agent
Washout from prior therapy: BTKi: no less than5 half-lives prior to epcoritamab to prevent BTKi rebound and rituximab: no less than 4 weeks (28 days) from last dose.
