Lupus Nephritis | Drug: RY_SW01 cell injection Drug: Basic treatment | Phase 2 |
This trial is an exploratory study, including two stages: the dose-escalation phase (Phase I) and the dose-expansion phase (Phase II), as part of a multicenter clinical trial. The Phase I dose-escalation stage employs a dose-escalation trial design, aiming to evaluate the safety, tolerability, and preliminary efficacy of RY_SW01 cell injection in treating patients with active lupus nephritis.
The Phase II dose-expansion stage utilizes a randomized controlled trial design to further evaluate the safety and effectiveness of RY_SW01 cell injection.
The baseline treatment in this trial includes steroids in combination with immunosuppressants. Common immunosuppressants include mycophenolate mofetil, mycophenolate sodium, cyclophosphamide, azathioprine, and calcineurin inhibitors (cyclosporine or tacrolimus), which will be chosen by the researchers based on the patient's condition. During Phase II, the subject's existing baseline treatment regimen must not be increased or changed. If a subject's treatment is assessed as ineffective or intolerable and continuing the existing baseline treatment regimen will not yield better benefits, they may withdraw from the trial and then change their treatment plan or increase the dosage. Such subjects should be included in the effectiveness analysis.The trial will enroll active lupus nephritis patients aged ≥18 and ≤65 years, who must meet all inclusion criteria and none of the exclusion criteria.
Approximately 69-78 subjects are planned to be enrolled to undergo the dose-escalation and dose-expansion trials with RY_SW01 cell injection. About 9-18 evaluable subjects will be enrolled in the dose-escalation stage, and approximately 60 subjects in the dose-expansion stage.
