Isatuximab in Patients With Monoclonal Gammopathy of Renal Significance
What this study is about
The purpose of this study is to see whether Isatuximab can help improve kidney function of participants with MGRS. Isatuximab is approved by the Food and Drug Administration (FDA) for the treatment of adult patients with multiple myeloma, but it is not approved by the FDA to treat MGRS. This means that the use of isatuximab in this study is considered 'experimental'.

Isatuximab is approved by the Food and Drug Administration (FDA) for the treatment of adult patients with multiple myeloma, but it is not approved by the FDA to treat MGRS. This means that the use of isatuximab in this study is considered 'investigational'.
Interventions
DRUG
Isatuximab
Isatuximab in IV form (10mg/kg q weekly x 4 doses followed by 10mg/kg q 2 weeks) for a total of 6 month duration. Doses should be initiated at 175 mg/hour up to a maximum of 400 mg/hour. Isatuximab (SAR) is monoclonal antibody (mAb).
Primary outcome measures
Overall Renal Response Rate
Time frame: Up to 6 months
Renal response defined as a decrease in 24-hour proteinuria by \>50% at any point post therapy.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Renal biopsy proven diagnosis of an MGRS disorder including the following: 1. Proliferative glomerulonephritis with monoclonal immunoglobulin deposits (PGNMID) 2. C3 glomerulopathy associated with monoclonal gammopathy 3. Non-Amyloid Fibrillary Glomerulonephritis 4. Light chain Proximal Tubulopathy 5. Immunotactoid Glomerulopathy A concurrent diagnosis of Monoclonal gammopathy (with +ve Serum and/or Urine protein electrophoresis or Bone marrow biopsy) is required in patients with C3 glomerulopathy but not for other disorders. Patients with concurrent MGUS, non-high risk smoldering myeloma are eligible for enrollment. 2. Measurable Proteinuria ≥1gram over 24 hours. 3. Prior Therapy: Newly diagnosed as well as patients with previous therapy but persistent renal dysfunction and persistent proteinuria ≥1gram over 24 hours are eligible for enrollment. Patients who received a prior cluster of differentiation 38 (CD38) antibody therapy are not eligi

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
