About this study

Official title: A Phase II Study of CART-ddBCMA for the Treatment of Patients With Relapsed or Refractory Multiple Myeloma

A Phase II study of anitocabtagene-autoleucel (formerly CART-ddBCMA) for patients with relapsed or refractory multiple myeloma. Anitocabtagene-autoleucel is a BCMA-directed CAR-T cell therapy.

Read the detailed description

This is a Phase II open-label study of anitocabtagene-autoleucel * in patients with relapsed or refractory multiple myeloma (MM). The study will have the following sequential phases: screening, enrollment, pre-treatment with lymphodepleting chemotherapy, treatment with anitocabtagene-autoleucel , and follow-up. If necessary, bridging therapy is allowed to control growth of MM disease while anitocabtagene-autoleucel is being manufactured.

Following a single infusion of anitocabtagene-autoleucel both safety and efficacy data will be assessed. Efficacy will be assessed monthly for the first 6 months, then quarterly up to 2 years, or upon patient relapse. The primary analysis will be conducted approximately 13 months after the final patient is dosed. This will allow approximately 12 months follow up from the time of the last observed response on study.

Long-term safety data will be collected under a separate long-term follow up study for up to 15 years per health authority guidelines.

*Anitocabtagene-autoleucel drug product consists of autologous T cells that have been genetically modified ex vivo to express a D-domain Chimeric Antigen Receptor (CAR), followed by a cluster of differentiation 8 (CD8) hinge and transmembrane region that is fused to the intracellular signaling domains for 4-1BB and CD3ξ, that specifically recognizes B-cell maturation antigen (BCMA). The active substance of anitocabtagene-autoleucel is CAR+ CD3+ T cells that have undergone ex vivo T-cell activation, gene transfer by replication-deficient lentiviral vector, and expansion.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing anitocabtagene-autoleucel in people with Multiple Myeloma, run by Kite, A Gilead Company at 18 sites 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 22 inclusion and 29 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 11 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 18 sites 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Overall Response Rate (ORR) (time frame: 24 Months). 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 11 Feb 2026.
