A Study of BEN301 Injection in the Treatment of Autoimmune Diseases

Plain-language summary
The study aims to investigate the safety, tolerability, and preliminary clinical efficacy of BEN301 Injection in patients with autoimmune diseases.
In patients with autoimmune diseases, Treg cells are typically deficient or dysfunctional. CAR-Treg cell therapy represents a promising strategy for the treatment of autoimmune diseases and may be applicable to a broad spectrum of autoimmune conditions. Preclinical studies have shown that BEN301Injection not only effectively suppresses the aberrant activation of T and B cells in SLE models, but also significantly reduces total lgG secretion and the production of SLE-specific autoantibodies, particularly anti-double-stranded DNA (dsDNA) antibodies. Moreover, no significant treatment-related toxicities were observed.
Treg cell therapy has already demonstrated favorable efficacy in multiple indications, including organ transplantation and autoimmune diseases, with a well-established safety and tolerability profile. Meanwhile, CAR-Treg cell therapy has been actively explored in various autoimmune conditions; several products have shown therapeutic potential, and some patients have already benefited from treatment. These findings highlight the promising prospects of CAR-Treg cell therapy in the management of autoimmune diseases.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
