About this study

Official title: An Open-Label Randomized Phase 2 Trial Of The NANT NEOADJUVANT Triple-Negative Breast Cancer (TNBC) VACCINE VS Standard-Of-Care For The Neoadjuvant Treatment Of Subjects With TNBC

This is a randomized open-label phase 2 study to evaluate the efficacy and safety (as assessed by pCR) of the NANT Neoadjuvant TNBC Vaccine regimen (experimental arm) compared to the SoC dose-dense regimen of doxorubicin/cyclophosphamide followed by paclitaxel (control arm).

Read the detailed description

Treatment will be administered in 2 phases, a neoadjuvant phase and a postoperative phase. The neoadjuvant phase will be 18 weeks for patients enrolled in the experimental arm and 16 weeks for those enrolled in the control arm.

Following the neoadjuvant phase, all subjects will undergo determination of their current response status and appropriate breast surgery and node dissection after which assessment for pCR will be conducted following completion of neoadjuvant systemic therapy. Pathologists interpreting surgical specimens for pCR assessment will be blinded to the treatment arm.

All subjects, regardless of whether or not they have achieved a pCR, will then enter the postoperative phase where they will receive adjuvant treatment. A small portion of the corresponding neoadjuvant therapy, either nab-paclitaxel or paclitaxel, will be administered as adjuvant treatment postoperatively. Adjuvant treatment will continue in the postoperative phase until the subject experiences unacceptable toxicity (not correctable with dose reduction), withdraws consent, or if the Investigator feels it is no longer in the subject's best interest to continue treatment.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Leucovorin, 5-Fluorouracil and Aldoxorubicin HCl in people with Triple Negative Breast Cancer (TNBC), 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 9 inclusion and 26 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The record says: withdrawn, as of the sponsor's last update on 21 Feb 2025.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 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?

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?

Pathological Complete Response Rate (time frame: 8 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 21 Feb 2025.
