About this study
Evaluation of the efficacy and safety of Thiotepa combined with Cyclophosphamide and Busulfan as conditioning regimen before allo-HSCT for the treatment of NK/T cell lymphoma
Read the detailed description
Although allo-HSCT brings certain survival benefits to patients with NK/T cell lymphoma, post-transplantation relapse remains the main cause of treatment failure and death. Therefore, it is crucial to further optimize the pre-transplantation conditioning regimen. Thiotepa is a non-specific cell cycle drug with good anti-tumor effects; it also has the dual functions of myeloablative and immunosuppressive effects, which can increase the implantation success rate, reduce the incidence of GVHD and recurrence rate. Currently, Thiotepa has become one of the preferred drugs for pre-transplantation conditioning in patients with primary central nervous system lymphoma and acute lymphoblastic leukemia. This study aims to add Thiotepa to the commonly used RIC conditioning regimen in order to explore an efficient and low-toxicity pre-transplantation conditioning regimen for allo-HSCT in NK/T cell lymphoma patients.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Thiotepa in people with NK T-Cell Lymphoma, run by Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine.
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 2 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 11 Dec 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.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
Contact Xianming Song, M.D (+86 189 1802 9692, shongxm@139.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
progression free survival (time frame: Two years after the transplantation). 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 11 Dec 2025.
