August 25, 2026 updated by: Fondazione Italiana Linfomi - ETS

Non-invasive Diagnostics and Monitoring of Minimal Residual Disease and Clonal Evolution in Waldenström's Macroglobulinemia and in IgM Monoclonal Gammopathy of Undetermined Significance

Multicenter retrospective and prospective observational study including patients with WM or IgM-MGUS evaluated at the time of diagnosis and during the disease course using highly sensitive techniques.

Detailed Description

Multicenter retrospective and prospective observational study including patients with WM or IgM-MGUS evaluated at the time of diagnosis and during the disease course using highly sensitive techniques such as flow cytometry, real time quantitative PCR (RT-qPCR), digital droplet PCR (dd-PCR) and NGS, in order to: evaluate the mutational status on genomic DNA or cell-free DNA and compare the results to assess the most reliable source for mutation studies; perform and compare molecular and flow cytometry analyses on bone marrow, peripheral blood (both analyses), plasma and urine samples (only molecular analysis) to assess the best source for diagnosis and MRD monitoring.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Probability Sample

Study Population

The study population will include either IgM-MGUS, asymptomatic WM or symptomatic WM patients requiring treatment. Patients in need of therapy will be treated according to recently published guidelines [49]. Patients treated with new agents, including the BTK inhibitor Ibrutinib, will be included. Patient enrolled retrospectively will constitute the learning cohort of the study, while those enrolled prospectively will constitute the validation cohort).

Description

Inclusion Criteria:

  • Diagnosis of IgM monoclonal gammopathy of undetermined significance (Ig-MGUS) or Waldenström's Macroglobulinemia (WM) according to criteria established at the second International Workshop on Waldenström's Macroglobulinemia [1]
  • Age ≥ 18 years
  • Previously untreated patients (only for the prospective cohort)
  • Symptomatic or asymptomatic disease
  • Subject understands and voluntarily signs an informed consent form approved by an Independent Ethics Committee (IEC)/Institutional Review Board (IRB)

Exclusion Criteria:

  • Active HBV, HCV or HIV infection (antiHBc+ patients with undetectable HBV-DNA are eligible to the study)

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Rate of mutation
Time Frame: 22 months
To demonstrate that the rate of mutations of MYD88 (L265P) and/or CXCR4 (S338X) detected in peripheral blood and/or urine show a negligible difference with the rate of mutations detected in bone marrow samples (BM, gold standard)
22 months
