Reversing autoimmunity in lupus using cell therapy

REACT-01: Reversing Autoimmunity Through Cell Therapy

Phase 1 Interventional Seattle Children's Hospital · NCT06465147

This study is testing a new cell therapy to see if it can help young people with lupus who haven't responded to other treatments.

What this trial studies

This phase 1, open-label study focuses on pediatric and young adult participants with treatment-refractory Systemic Lupus Erythematosus (SLE). The study aims to evaluate the safety, feasibility, and efficacy of genetically modified T cell products derived from peripheral blood mononuclear cells (PBMC) that express a CD19 specific chimeric antigen receptor (CAR). Participants will undergo apheresis to collect their T cells, which will then be bioengineered to target B cells involved in the autoimmune response. The study is designed to provide insights into a novel therapeutic approach for a challenging condition.

Who should consider this trial

Good fit: Ideal candidates are children and young adults aged 2-30 years with serologically active Systemic Lupus Erythematosus that has not responded to standard treatments.

Not a fit: Patients who are not refractory to treatment or who do not meet the specific eligibility criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new, effective option for patients with refractory Systemic Lupus Erythematosus.

How similar studies have performed: While this approach is innovative, similar CAR T cell therapies have shown promise in other autoimmune conditions, suggesting potential for success in this context.

Inclusion Criteria:

* Male and female subjects aged between 2-30 years old. The first 3 subjects will be aged ≥ 17. The FDA will review safety data to determine if the age can be lowered first to ≥ 12 then, following the treatment of 3 further subjects aged 12-17, to ≥ 2
* Serologically active Systemic Lupus Erythematosus that is refractory to treatment
* Able to tolerate apheresis or already has an apheresis product available for use in manufacturing.
* ≥ 24 weeks post last Rituximab or related B cell depleting therapy
* ≥ 12 weeks post last Belimumab / Anifrolumab therapy
* ≥ 4 weeks post last calcineurin inhibitor treatment
* For subjects receiving non-calcineurin immunosuppressive therapy, on a stable dose for ≥ 8 weeks before enrollment
* For subjects receiving corticosteroid therapy, on a stable dose for ≥ 2 weeks before enrollment
* Adequate organ function
* Adequate laboratory values
* Subjects of childbearing or child-fathering potential must agree to use highly effective contraception from consent through 12 months following infusion of investigational product on trial
* Subjects must be willing to remain within 1 hour's drive of Seattle Children's Hospital for 4 weeks following CAR T cell infusion.

Exclusion Criteria:

* History or presence of active CNS lupus or other CNS disease

* Active or prior malignancy, unless the malignancy was treated and there is no evidence of recurrent disease \<5 years from enrollment.
* Prior solid organ transplantation.
* Presence of an active severe infection
