A Basket Study of CTA313 in Participants With Active Autoimmune Diseases

Not Yet RecruitingPhase 1

Sponsor: Imviva Bio

Conditions: Systemic Lupus Erthematosus (SLE), Progressive Multiple Sclerosis (PMS), Autoimmune Encephalitis

Interventions: CTA313 UCAR T Cell Infusion

The goal of the ALLNEW clinical trial is to learn if CTA313 UCART is safe and effective for patients with immune mediated disorders. Participants with SLE, pMS and AIE between the ages of 18 and 75 will be eligible to participate. Participants will receive one infusion of CTA313 on Day 0. During the Dose Confirmation portion, cohorts will be independently evaluated for safety and to establish the RP2D of CTA313. During the Cohort Expansion portion of the study patients will be evaluated to further confirm the efficacy and safety of CTA313. Patients will be followed for up to 24 months in this study and will be required to enroll under a separate long term follow up protocol to be followed for up to 15 years.
