Cancer drug could ease rare nerve disorder
NCT ID NCT07392229
First seen Jun 25, 2026 · Last updated Aug 28, 2026 · Updated 2 times
Summary
This study tests whether zanubrutinib, a drug used for certain blood cancers, can improve nerve function in people with anti-MAG neuropathy—a rare condition causing numbness, weakness, and balance problems. About 50 adults in Italy will take the drug for 12 months. Researchers will check if symptoms get better using standard nerve tests.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Zanubrutinib (a targeted cancer drug that blocks a protein called BTK)
- What this could lead to
- If successful, this could offer a new treatment option for a rare nerve disease that currently has few effective therapies.
- What could go wrong
- This is an early-phase trial with only 50 participants and no placebo group, so results may not be definitive. The drug also carries risks like infection and bleeding.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria (MAIN): * age ≥18 years; * diagnosis of anti-MAG antibody polyneuropathy; * neurophysiological (ENG/EMG) evidence of a demyelinating polyneuropathy with evidence of disproportionately prolonged distal motor latency in one or more nerves -excluding the median nerve if related to carpal tunnel syndrome * IgM monoclonal protein underlying MGUS (based on the WHO definition of clonal lympho- plasmocytes \<10%), Waldenstrom macroglobulinemia (based on the WHO definition of clonal lympho-plasmocytes ≥10%), marginal zone lymphoma, chronic lymphocytic leukemia or low- grade lymphoma not otherwise specified; * presence of anti MAG antibodies (titer ≥ 7.000 BTU); * neurophysiological (ENG/EMG) evidence of demyelinating polyneuropathy. Exclusion Criteria (MAIN): * Previous treatment with BTK inhibitors * Aggressive non-Hodgkin lymphoma or IgM multiple myeloma * Evidence of moderate or severe motor nerve axonal damage, defined when occurring diffuse polyneuropathic denervation or a recruitment pattern lower than intermediate in ≥50% of muscles examined, and/or INCAT at lower limbs ≥4. * ECOG \>3 * Use of strong CYP3A inducers within 14 days prior to the first dose of zanubrutinib
