Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Age ≥ 18 years.
  • Able to understand and provide a signed informed consent that fulfills the relevant IRB or Independent Ethics Committee (IEC) guidelines.
  • Histologically-confirmed recurrent or unresectable chordoma that would require radiation as a primary means for treatment.

  • Have at least 1 measurable lesion of ≥ 1.0 cm.
  • Must have a recent formalin-fixed, paraffin-embedded (FFPE) tumor biopsy specimen following the conclusion of the most recent anticancer treatment and be willing to release the specimen for prospective and exploratory tumor molecular profiling. If an historic specimen is not available, the subject must be willing to undergo a biopsy during the screening period, if considered safe by the Investigator. If safety concerns preclude collection of a biopsy during the screening period, a tumor biopsy specimen collected prior to the conclusion of the most recent anticancer treatment may be used.

About this study

Official title: QUILT-3.091 NANT Chordoma Vaccine: A Randomized Phase 1b/2 Trial of the NANT Chordoma Vaccine vs. Radiation in Subjects With Unresectable Chordoma.

QUILT 3.091 Chordoma Vaccine: Phase 1B/2 NANT Chordoma Vaccine vs Radiation in Subjects with Unresectable Chordoma.

Read the detailed description

The NANT Chordoma Vaccine regimen will be administered in 2 phases, an induction and a maintenance phase.

Subjects will continue induction treatment for up to 1 year. Those who have a confirmed complete response (CR) in the induction phase will enter the maintenance phase of the study. Subjects who experience ongoing stable disease (SD) or an ongoing partial response (PR) at 1 year may enter the maintenance phase at the Investigator's and Sponsor's discretion. Subjects may remain in the maintenance phase of the study for up to 1 year.

In the randomized component of the phase 2 portion of the study, the control arm will be treated with radiation according to established SoC protocols as determined by the Investigator.

In the phase 2 single-arm component of the study, subjects will be enrolled in the first stage of Simon's two-stage optimal design. If the study proceeds to the second stage of Simon's two-stage optimal design, additional subjects will be enrolled in the second stage.

Being tested

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Aldoxorubicin Hydrochloride, ALT-803 and ETBX-051 in people with Chordoma and Unresectable Malignant Neoplasm, run by ImmunityBio, Inc. 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 12 inclusion and 18 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: withdrawn, as of the sponsor's last update on 21 Feb 2025. 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 combined 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.

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?

The study was withdrawn before enrolling participants, so there are no results.

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?

Incidence of treatment-emergent Adverse Events (AEs) and Serious Adverse Events (SAEs), graded using the NCI CTCAE Version 4.03. (time frame: 9 weeks). The study lists 2 primary outcomes in all. 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 21 Feb 2025.
