DLBCL
Conditions
Brief summary
This trial is a prospective, multi-center, single-arm clinical research. The intention is to evaluate the efficacy and safety of pirtobrutinib combined with BEAM as a pretreatment regimen for ASCT in relapsed and refractory DLBCL patients.
Detailed description
A total of 28 patients with relapsed/refractory DLBCL are planned to be enrolled in this trial. They will receive pirtobrutinib in combination with the BEAM regimen as conditioning therapy, followed by ASCT. The study comprises a screening period, a treatment period (days -8 to -2, 7 days in total), and a 2-year follow-up period after transplantation.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Progression-free survival | Baseline up to data cut-off (up to approxiamately 2 years) | Progression-free survival was defined as the time from the data of ASCT until the date of the first documented day of disease progression or relapse, using Lugano criteria, or death from an cause, whichever occured first. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Overall survival | Baseline up to data cut-off (up to approxiamately 2 years) | Overall survival was defined as the time from the date of ASCT to the date of death from any cause |
| Complete remission rate | 3 months after the transplantation | Percentage of participants with complete response was determined on 2014 Lugano criteria |
| The time of hematopoietic reconstruction | 2 months after the transplantation | The first day of neutrophils ≥0.5\*109/L for 3 consecutive days was the time of successful implantation of granulocytes. Platelet ≥20.0\*109/L for 7 consecutive days and the first day after platelet infusion was considered as the successful time of megakaryocytes implantation |
| Transplantation-related adverse reactions | Baseline up to data cut-off (up to approxiamately 4 years) | Transplantation-related adverse reactions are any untoward medical occurrence in a participant which is related to ASCT. |
