What is being measured

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

  1. Number of Participants with progression free survival with the group taking KRd versus VRd after randomization

    Measured: 5 years

Secondary outcomes (4)

  1. The rate of MRD-negative (minimal residual disease) at indicated time points of study after randomization

    Measured: 5 years

  2. The combination of drugs (KRd vs VRd) with the best response using minimal residual disease analysis across entire treatment in high risk and low risk patients

    Measured: 5 years

  3. The combination of drugs (KRd vs VRd) safety and tolerability based on patients response

    The safety and tolerability of lenalidomide and carfilzomib will be evaluated by means of drug related Adverse Events reports.

    Measured: 5 years

  4. Evaluate the correlation between treatment outcome using KRd or VRd and pre-treatment

    Measured: 5 years

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Carfilzomib, Lenalidomide and Dexamethasone in people with Multiple Myeloma, run by University of Chicago 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 21 inclusion and 27 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: under way, not looking for participants, as of the sponsor's last update on 4 Mar 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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?

Number of Participants with progression free survival with the group taking KRd versus VRd after randomization (time frame: 5 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03729804.

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 4 Mar 2026; AzTrials last refreshed its copy on 8 Nov 2026.
