CD7 CAR-T in the Treatment of CD7 Positive Refractory Relapsed Acute Leukemia
China20 participantsStarted 2021-03-04
Plain-language summary
Patients with acute leukemia derived from T lymphocytes have the characteristics of high expression of CD7 antigen, such as acute T lymphocyte leukemia (T-ALL).CAR-T therapy is to genetically modify the patient's T lymphocytes to target and eliminate tumor cells in a major histocompatibility complex-independent manner. CAR-T cells are costimulatory molecules that include single-chain antibodies (scFv) that recognize tumor-specific antigens, hinge regions, transmembrane regions, intracellular signaling regions (immunoreceptor tyrosine activation motif ITAM), and intracellular signaling regions. The chimeric antigen receptor of CD28 or CD137(4-1BB) conduction domain is expressed in a lentiviral vector, and the vector is transfected into autologous T cells, so that the modified CAR-T cells have targeting and specificity Recognizes and kills cancer cells expressing tumor antigens, and can proliferate and activate in vivo, but has no effect on cells that do not express the antigen

Questions worth asking your doctor
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?

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?
