Daratumumab in Treatment of PGNMID and C3 GN

August 26, 2022 updated by: Fernando Fervenza

Single-center Phase 2 Open-label Trial Evaluating Efficacy and Safety of Daratumumab in Treatment of Patients With Proliferative Glomerulonephritis With Monoclonal Immune Deposits and C3 Glomerulopathy Associated With Monoclonal Gammopathy

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study is an open-label phase 2 trial of the safety and efficacy of daratumumab, in the treatment of PGNMID and C3GN associated with monoclonal gammopathy. Subjects will be screened at outpatient Nephrology Clinic visit appointments and interested qualified subjects will be consented and offered participation in this trial. Once consent has been obtained baseline values will be established and subjects will begin treatment and follow-up for the next 12 months. Daratumumab will be administered once weekly for 8 weeks and then once every 2 weeks for 8 additional doses. Patients will be followed for a total of 12 months (6 months after the last infusion). A final visit for evaluation and collection of lab samples will be conducted at the end of the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Time Frame: 1 year
Number of treatment-emergent adverse events as defined as major infection (defined as the development of pneumonia, severe urinary tract infection/pyelonephritis, sepsis, meningitis), grade 3 or 4 anemia, leukopenia, or thrombocytopenia.

Secondary Outcome Measures

Secondary Outcome Measures
