About this study
Official title: A Prospective, Multicenter Clinical Study of Relmacabtagene Autoleucel Combined With Autologous Hematopoietic Stem Cell Transplantation, Orelabrutinib, and Sintilimab for Primary Central Nervous System Lymphoma

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Relmacabtagene autoleucel and transplantationDrug
This study enrolled patients with primary central nervous system lymphoma, from whom mononuclear cells and hematopoietic stem cells were collected. Participants receive infusions of hematopoietic stem cells and CAR-T cells, followed by maintenance therapy with orelabrutinib and sintilimab starting on day 15 post-transplantation, for a median duration of up to 6 months and 1 year, respectively.

What is being measured
The primary outcome is the main question the study is designed to answer.
progression-free survival(PFS)
PFS is defined as the time from CAR-T infusion to the first occurrence of either disease progression or death from any cause, whichever comes first, regardless of whether study treatment has been discontinued prior to the PFS event.
Measured: Up to 60 months
overall response rate(ORR)
Measured: Up to 3 months
Secondary outcomes (1)
Overall Survival (OS)
Measured: Up to 60 months

Questions about this trial
What is this clinical trial studying?
A study testing Relmacabtagene autoleucel and transplantation in people with Primary Central Nervous System Lymphoma (PCNSL), run by Zhengzhou University.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 30 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
progression-free survival(PFS) (time frame: Up to 60 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Sep 2025.
