What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • UB-VV500Genetic

    UB-VV500 is a gene therapy that generates CAR T cells that target both B-cell maturation antigen (BCMA) and G protein-coupled receptor, family C, group 5, member D (GPRC5D) in the body.

  • Rapamycin (sirolimus)Drug

    Rapamycin is a drug approved by the FDA for indications unrelated to cancer.

Study groups in NCT07735546
Study groupRoleWhat they receive
UB-VV500ExperimentalA single dose of UB-VV500 will be administered.
Receives: Genetic: UB-VV500
UB-VV500 + rapamycinExperimentalA single dose of UB-VV500 will be administered followed by treatment with rapamycin.
Receives: Genetic: UB-VV500; Drug: Rapamycin (sirolimus)

What is being measured

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

  1. Percentage of participants with common adverse events (AEs)

    Percentage of participants with commonly reported AEs overall and by severity

    Measured: Up to 2 years after UB-VV500 administration

Secondary outcomes (1)
  1. Overall response rate (ORR)

    Percentage of participants with a best overall response (BOR) of complete response (CR) or partial response (PR)

    Measured: Up to 2 years after UB-VV500 administration

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing UB-VV500 and Rapamycin (sirolimus) in people with Multiple Myeloma in Relapse and Multiple Myeloma (MM), run by Umoja Biopharma.

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 7 inclusion and 11 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: opening soon, as of the sponsor's last update on 17 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Contact Luke Walker, MD (206-227-5056, luke.walker@umoja-biopharma.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of participants with common adverse events (AEs) (time frame: Up to 2 years after UB-VV500 administration). 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 17 Aug 2026.
