Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults 18–70 with relapsed or treatment-refractory SLE, AAV, SSc, or IIM who meet the disease classification criteria, have the required antibody/marker positivity (including CD19 and/or BCMA), and meet laboratory safety criteria.

Probably not a fit

Patients without CD19 or BCMA positivity, with uncontrolled infections or serious comorbidities, or who do not meet the specific disease classification or laboratory criteria are unlikely to benefit from this trial.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective, single-arm, open-label, dose-escalation early-phase trial testing LUCAR-DKS1, a chimeric antigen receptor (CAR) NK-cell therapy, in adults with relapsed or refractory autoimmune diseases. Participants will undergo screening, receive lymphodepleting chemotherapy, then a single infusion of LUCAR-DKS1 followed by planned follow-up visits to monitor safety, pharmacokinetics, and signals of efficacy. The protocol enrolls patients meeting disease-specific classification criteria (for SLE, AAV, SSc, or IIM) with relevant antibody or marker positivity and acceptable laboratory parameters. The primary focus is on safety and tolerability, with secondary collection of pharmacologic and preliminary effectiveness data.

Why it matters

Potential benefit: If successful, this approach could reduce autoimmune activity and produce durable remissions in patients who have not responded to standard therapies.

How similar studies have gone: Targeting B cells with cellular therapies (notably CAR-T) has shown promising but early results in some refractory autoimmune conditions, while CAR-NK approaches are novel and have only limited clinical data so far.
