About this study

Official title: A Phase 1 Study Evaluating the Safety and Preliminary Efficacy of ALLO-329, a Dual Anti-CD19/Anti-CD70 Allogeneic CAR T Cell Product in Autoimmune Disease

This is a first-in-human, single-arm, open-label study evaluating the safety, tolerability, and preliminary efficacy of ALLO-329 in adults with autoimmune diseases: systemic lupus erythematosus (SLE) with and without renal involvement, idiopathic inflammatory myopathy (IIM), and systemic sclerosis (SSc).The purpose of this trial is to evaluate the safety and tolerability of ALLO-329, an allogeneic anti-CD19, anti-CD70 dual chimeric antigen receptor (CAR) T cell therapy, in adults with autoimmune disorders, provide initial evidence of biological activity and clinical response to the treatment and determine the recommended Phase 2 regimen (RP2R).

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ALLO-329, Cyclophosphamide and Fludarabine in people with Systemic Lupus Erythematosus (With and Without Nephritis) and Idiopathic Inflammatory Myopathy, run by Allogene Therapeutics at 18 sites in 2 countries.

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 13 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: looking for participants now, as of the sponsor's last update on 2 Nov 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, Canada. 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 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 Allogene Therapeutics, Inc. (+1 415-604-5696, clinicaltrials@allogene.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of Dose Limiting toxicities (DLTs) and Other Safety Parameters (time frame: Up to 60 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 2 Nov 2026.
