Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 to 65 with a diagnosis of severe myositis who have not adequately responded to previous treatments.
✕Probably not a fit
Patients with other inflammatory myopathies or those with severe muscle damage or inadequate organ function may not benefit from this study.

What this trial studies
This Phase 2 clinical trial aims to assess the efficacy and safety of rapcabtagene autoleucel, a chimeric antigen receptor T cell therapy, in patients with severe refractory idiopathic inflammatory myopathies (IIM). The study includes a lead-in cohort receiving the therapy and a randomized cohort comparing it to an active control. Participants will be monitored for two years, followed by a long-term follow-up period lasting up to 15 years. The trial is designed to provide insights into the potential benefits of CAR-T therapy for this challenging condition.
Why it matters
Potential benefit: If successful, this therapy could offer a new treatment option for patients with severe myositis who have not responded to existing therapies.
How similar studies have gone: While CAR-T therapies have shown promise in other conditions, this specific application in myositis is relatively novel and untested.

Show full inclusion / exclusion criteria
Key Inclusion Criteria: 1. Men and women, aged ≥ 18 and ≤75 years, with a diagnosis of probable or definite myositis according to American College of Rheumatology/European League Against Rheumatism 2017 (ACR/EULAR 2017) criteria 2. Participants who had inadequate response to prior therapy 3. Diagnosed with active disease 4. Participant must meet criteria for severe myositis Key Exclusion Criteria: 1. Any condition during Screening that could prevent a complete washout of medications or could otherwise make the participant ineligible for anti-CD19 CAR-T therapy and further participation in the study 2. BMI at Screening of ≤17 or ≥40 kg/m2 3. Severe muscle damage at Screening 4. Inadequate organ function 5. Hypersensitivity and/or contraindications to any product (including its ingredients) to be given to the participant as per the study protocol 6. Other inflammatory and non-inflammatory myopathies 7. Any medical conditions that are not related to IIM that would jeopardize the ability of the participant to tolerate CD19 CAR-T cell therapy Other protocol-defined inclusion/exclusion criteria may apply.
