Open-label Trial of Daratumumab in Treatment of PGNIMD and C3 GN

Overview

  • Study type

    Interventional
  • Study phase

    II
  • Study IDs

  • Describes the nature of a clinical study. Types include:

    • Observational study — observes people and measures outcomes without affecting results.
    • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
    • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
  • During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study

This study is being done to see if daratumumab is safe and effective in the treatment of proliferative glomerulonephritis with monoclonal immune deposits (PGNMID) and C3 glomerulopathy associated with monoclonal gammopathy (C3GN). This is an inflammatory disease in the kidney due to the production of abnormal proteins. There are no known standard effective treatments for patients with PGNMID and C3GN secondary to monoclonal gammopathy. These diseases are caused by abnormal production of proteins (monoclonals) by abnormal clones. Daratumamb has been shown to be effective in treating patients with multiple myeloma a disease which also caused by over production of monoclonal proteins from abnormal clones. Everyone in this study will receive daratumumab.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.
