Keywords
DLBCL, Orelabrutinib, CD5-positive, R-CHOP
Brief summary
This is a prospective, single-arm, multicenter, phase II clinical trial to evaluate the efficacy and safety of orelabrutinib combined with the R-CHOP (rituximab, cyclophosphamide, vincristine, doxorubicin, and prednisone) regimen as first-line treatment in CD5-positive diffuse large B-cell lymphoma (DLBCL) patients.
Detailed description
The purpose of this phase II clinical trial is to evaluate the efficacy and safety of orelabrutinib in combination with R-CHOP for untreated CD5-positive DLBCL patients. The induction phase consisted of 6 cycles of orelabrutinib in combination with R-CHOP (orelabrutinib added from the second cycle), followed by 2 cycles of rituximab + orelabrutinib, for a total of 8 treatment cycles. After 8 cycles of induction therapy, if the response is assessed as complete remission (CR), maintenance therapy with orelabrutinib will be conducted. The primary endpoint is the 2-year event-free survival (EFS) rate.
Interventions
Orelabrutinib (150 mg po D1-D21) is added from the second cycle of R-CHOP regimen
Rituximab, Cyclophosphamide, Doxorubicin, Vincristine, Prednisone

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 2-year event-free survival (EFS) rate | Defined as the proportion of patients without disease progression, treatment discontinuation, or death for any reason within 24 months of enrollment | To investigate the preliminary anti-tumor efficacy |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Complete response rate (CRR) | Up to 8 cycles (each cycle is 21 days) | To investigate the preliminary anti-tumor efficacy |
| Disease-free survival (DFS) | From date of the first complete response until the date of the first documented progression or date of death from any cause, whichever came first, assessed up to 24 months | To investigate the preliminary anti-tumor efficacy |
| Objective response rate (ORR) | Up to 8 cycles (each cycle is 21 days) | To investigate the preliminary anti-tumor efficacy |
| Overall survival (OS) | From the date of enrollment until the date of death from ant cause, assessed up to 24 months | To investigate the preliminary anti-tumor efficacy |
| Number of participants with adverse events (AE) and severe adverse events (SAE) as assessed by CTCAE v5.0 | Through study completion, an average of 2 years | To identify the incidence of AE and SAE |
| Progression-free survival (PFS) | From the date of enrollment until the date of the first documented progression or date of death from any cause, whichever came first, assessed up to 24 months | To investigate the preliminary anti-tumor efficacy |
Other
| Measure | Time frame | Description |
|---|---|---|
| The correlation of gene mutations and alterations in relevant signaling pathways with the efficacy and survival in CD5-positive DLBCL | Through study completion, an average of 2 years | To explore the correlations between gene mutations and response and prognosis |
