PD-1 Inhibitors +Venetoclax+CAG Regimens in R/R T-ALL
China40 participantsStarted 2025-05-01
Plain-language summary
This prospective multicenter study evaluates the efficacy and safety of PD-1 inhibitor combined with venetoclax and HAG/CAG chemotherapy in refractory/relapsed T-ALL (R/R T-ALL). Despite standard chemotherapy, R/R T-ALL remains challenging, with low salvage remission rates (\~40%) and poor survival. Preclinical data suggest PD-1 blockade enhances leukemic stem cell eradication, while venetoclax (BCL-2 inhibitor) synergizes with chemotherapy. Eligible patients receive 1-2 cycles of PD-1 inhibitor + venetoclax + CAG, with responders proceeding to allo-HSCT or MRD-guided consolidation. The trial aims to improve CR rates and survival, offering a novel immunochemotherapy approach for this high-risk population.

Inclusion criteria
. Age \>=18 years old;
. Met the T-ALL diagnosis before enrollment (for specific diagnostic criteria, see the attachment);
. Refractory T-ALL (newly diagnosed T-ALL that fails to achieve remission after treatment with one standard regimen) or recurrent T-ALL (bone marrow blasts exceed 5% again after remission, and the morphology and immunophenotype of leukemia cells are consistent with T-ALL);
. The performance status score of the Eastern Cooperative Oncology Group (ECOG) in the United States ranges from 0 to 2 points.
. Expected survival period \>=3 months;
. During the screening period, there were no organ function abnormalities that restricted the use of this scheme.
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?
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.

Exclusion criteria
