Could a One-Time immune cell treatment tame severe vasculitis?
NCT ID NCT06868290
First seen Jun 27, 2026 · Last updated Sep 04, 2026 · Updated 1 time
Summary
This Phase 2 trial tests a one-time infusion of rapcabtagene autoleucel, a CAR-T cell therapy made from a patient's own immune cells, against standard treatments for severe active granulomatosis with polyangiitis (GPA) or microscopic polyangiitis (MPA). About 126 adults aged 18-75 with confirmed ANCA-positive vasculitis will be enrolled. The goal is to see if this cell therapy can control the disease better than usual care and reduce the need for steroids.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- rapcabtagene autoleucel (a CAR-T cell therapy made from the patient's own immune cells)
- What this could lead to
- If it works, this could offer a new way to control severe vasculitis without long-term heavy medications, potentially reducing flares and steroid dependence.
- What could go wrong
- This is an early Phase 2 trial with only 126 participants, so results may not apply to everyone. CAR-T therapies can cause serious side effects like cytokine release syndrome or infections.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Key inclusion criteria: 1. Men and women, aged ≥18 and ≤ 75 years with a diagnosis of GPA or MPA according to the American College of Rheumatology/ European League Against Rheumatism 2022 (ACR/EULAR 2022) classification criteria 2. Positive test for ANCA-autoantibodies 3. GPA and MPA participants with severe active disease Key exclusion criteria: 1. Any condition 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. Hypersensitivity and/or contraindications to any product to be given to the participant as part of the study protocol 3. Other systemic autoimmune diseases requiring therapy 4. Any medical conditions that are not related to GPA/MPA that would jeopardize the ability of the participant to tolerate CD19 CAR-T cell therapy 5. Inadequate organ function
