About this study

Official title: The Effect of Novel Treatments in Improving Renal Outcomes Among Patients With Light Chain Cast Nephropathy

Objective 1: To test whether treatment with plasma exchange improves renal recovery in patients with light chain cast nephropathy Objective 2: To compare renal outcomes among patients treated with plasma exchange versus daratumumab-based regimens versus non-daratumumab based-regimens.

Read the detailed description

Objective 1:

We will collect data from patients treated with plasma exchange from major centers across the United States to investigate whether plasma exchange improves renal outcomes.

Specifically, we will collect data on at least 150 patients treated with plasma exchange along with 300 control patients not treated with plasma exchange.

Objective 2:

We will compare renal outcomes among patients with light chain cast nephropathy and AKI treated with plasma exchange (n=150) versus daratumumab based regimen (eg Dara-CyborD) (n=150) versus other novel regimens (e.g., CyborD or another non-daratumumab-based regimen) (n=150). We will examine whether patients who receive dara-based regimens are more likely to have renal recovery compared to patients who do not receive dara-based regimens and to patients who receive plasma exchange. Given the infrequency with which plasma exchange is performed on a single-center level, we will compare outcomes among patients treated with plasma exchange, utilizing data from the multicenter study to those patients who were treated with daratumumab-based regimens without plasma exchange versus non- daratumumab-based regimen.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The primary composite outcome is the rate of survival with renal recovery within 90 days from the diagnosis of light chain cast nephropathy.

    To meet the primary outcome, patients must be alive, not RRT-dependent (e.g., were never on dialysis/no longer on dialysis), and have a decline of at least one stage of AKI severity compared to their highest AKI stage achieved at the time of light chain cast nephropathy-associated AKI. AKI staging will be based on the Kidney Disease Improving Global Outcomes (KDIGO) criteria, where stage 1 is a 1.5-1.9-fold rise in SCr from baseline; stage 2 is a 2-2.9-fold rise from baseline; and stage 3 is a 3-fold rise in SCr from baseline or initiation of RRT. Baseline SCr is defined as the lowest SCr in the 365 days preceding the diagnosis of light chain cast nephropathy.

    Measured: 90 days

Secondary outcomes (8)
  1. The proportion of patients with Receipt of RRT within 30 days, 60 days, and 90 days following diagnosis of light chain cast nephropathy

    The proportion of patients with Receipt of RRT within 30 days, 60 days, and 90 days following diagnsosis of LCCN

    Measured: 30, 60, 90 days

  2. The proportion of patients with Progressive AKI

    Defined as progression from existing AKI (stage 2) to a higher stage (stage 3 or receipt of RRT) within 30, 60, and 90 days following diagnosis of light chain cast nephropathy. AKI staging at each of these time points will be defined based on KDIGO criteria outlined above.

    Measured: 30, 60, 90 days

  3. Survival to hospital discharge

    Survival to hospital discharge and KRT-independent among patients admitted within 30 days of the diagnosis of light chain cast nephropathy.

    Measured: 30 days

  4. Renal function (SCr) at hospital discharge

    Renal function (SCr) at hospital discharge (% increase compared to baseline) among patients who are admitted within 30 days of their diagnosis of light chain cast nephropathy

    Measured: 30 days

  5. Time to first renal recovery

    Renal recovery will be defined as not RRT-dependent, and with nadir SCr returning to <50% of baseline. This will be assessed within 180 days following the diagnosis of light chain cast nephropathy

    Measured: 180 days

  6. Kidney recovery

    at 30 (+/-15), 60 (+/-15), 90 (+/-30) days, and 180 days (+/-60 days) following the diagnosis of light chain cast nephropathy, , defined as survival, KRT-independent, and with SCr <1.5-fold baseline at each of the above time points.

    Measured: 30 (+/-15), 60 (+/-15), 90 (+/-30) days, and 180 days (+/-60 days)

  7. Overall survival at day 90, 180, 360, with day 0 defined as date of LCCN diagnosis. Patients who die within 48 hours of the diagnosis will be excluded.

    At day 90, 180, 360, with day 0 defined as date of LCCN diagnosis

    Measured: 90, 180, 360 days

  8. Adverse events

    Infection, re-hospitalization, transfusion reactions, bleeding diatheses.

    Measured: 60 days

Questions about this trial

What is this clinical trial studying?

An observational study of Multiple Myeloma and Light Chain Nephropathy, run by Brigham and Women's Hospital at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 20 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 9 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The primary composite outcome is the rate of survival with renal recovery within 90 days from the diagnosis of light chain cast nephropathy. (time frame: 90 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Jul 2026.
