Feasibility and Safety of Collecting and Combining Autologous Hematopoietic Stem Cells With Chimeric Antigen Receptor (CAR) T-Cell Therapy in Subjects With Relapsed/Refractory Hematological Malignancies
United States20 participantsStarted 2024-03-02
Plain-language summary
The study is designed to examine the feasibility and safety of collecting autologous hematopoietic stem cells (HSCs) to be combined with CAR T-cell therapy for patients with relapsed/refractory (r/r) hematological disease. The study will evaluate feasibility of collecting the target dose of HSCs from at least 50% of enrolled patients. The study will assess safety based on incidence and severity of cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) in the first 60 days post CAR T dosing, and also through the collection of adverse events (AEs) and serious adverse events (SAEs) as well as the durability of response after treatment with HSCs with CAR T. The study follows an open-label, single-center and single non-randomized cohort design. 20 subjects with r/r hematological malignancies will be enrolled and treated to evaluate the feasibility and preliminary safety of collecting autologous HSCs and combining them with CAR T-cell therapy.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Age 18 - 85 years.
* Histologically proven hematological malignancy according to the World Health Organization 2016 classification criteria for which a commercially available, FDA-approved CAR T product exists.
* Relapsed or refractory disease, defined by the following:
* Disease progression after last regimen, or
* Refractory disease: failure to achieve a partial response (PR) or complete remission (CR) to the last regimen
* At least 2 weeks or 5 half-lives, whichever is shorter, must have elapsed since any prior systemic therapy for the malignancy at the time the subject is planned for leukapheresis.
* Toxicities due to prior therapy must be stable or recovered to ≤ Grade 1 with the exception of alopecia.
* Subjects with an active uncontrolled infection should not start CAR T treatment until the infection has resolved.
* Eastern cooperative oncology group (ECOG) performance status 0 - 2.
* Adequate hematologic, hepatic, and cardiac function
* Serum pregnancy test for women of childbearing potential (WOCBP) at Screening.
* Willing to comply to research specimen collection as specified in the protocol.
* Written informed consent obtained from subject and ability for subject to comply with the requirements of the study.
Exclusion Criteria:
* Autologous hematopoietic cell transplant intent or execution within 8 weeks of planned CAR T infusion.
* History of allogeneic cell transplantation within 8 weeks of planned CAR T infusion.
* Presence or suspi…
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?

What they're measuring
1
To assess feasibility of collecting the target HSC cell dose for at least 50% of enrolled patients.
Timeframe: From Day 0 (CAR T infusion) to Day 10 (aHSC infusion).
2
To assess safety of aHSC to planned CAR T therapy in the first 60 days through the incidence, severity, and duration of CRS based on the American Society for Transplantation and Cellular Therapy (ASTCT) consensus grading system.
Timeframe: From Day 0 to Day 60.
3
To assess safety of aHSC to planned CAR T therapy in the first 60 days through the incidence, severity, and duration of ICANS based on the American Society for Transplantation and Cellular Therapy (ASTCT) consensus grading system.
