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

This trial does not accept healthy volunteers

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.

Trial outcomes

Primary outcomes

1

Overall Response Rate (ORR)

The overall response rate (ORR) was defined as the proportion of participants achieving complete response (CR) or partial response (PR) based on modified IWWM6 criteria.

Time frame
Up to 12 cycles of treatment (28 days per cycle)

Secondary outcomes

1

6-month Best Response Rate

Best response on treatment was based on modified IWWM6 criteria. Including complete response (CR), very good partial response (VGPR), partial response (PR), stable disease (SD) and progressive disease (PD). Rate defined as the proportion of participants achieving the certain response.

Time frame
6 months
2

Major Response Rate (MRR)

MMR defined as proportion pf participants achieving the major response includes PR, VGPR, and CR based on IWWM6 criteria.

Time frame
Up to 12 cycles of treatment (28 days per cycle)
3

Median Time to Best Response

Best response on treatment was based on modified IWWM6 criteria. Time to event outcome estimate using Kaplan-Meier method.

Time frame
Up to 12 cycles of treatment (28 days per cycle)
4

Median Duration of Overall Response (DOR)

Duration of Overall Response (DOR), estimated using the Kaplan Meier method, is measured from the time measurement criteria are met for CR or PR (whichever is first recorded) per modified IWWM6 criteria, until the first date that recurrent or progressive disease is objectively documented. Participants without progressive disease are censored at the date of last disease assessment.

Time frame
Up to 12 cycles of treatment (28 days per cycle)
