Combining Orelabrutinib with Bendamustine and Rituximab for treating Mantle Cell Lymphoma

A Multicenter, Open-label, Randomized Controlled Study of Orelabrutinib in Combination With Bendamustine and Rituximab Versus Bendamustine and Rituximab in the Treatment of Transplant-Ineligible, Intermediate- to High-Risk Mantle Cell Lymphoma (MCL)

Phase 3 Interventional Ruijin Hospital · NCT06496308

This study is testing if adding Orelabrutinib to the standard treatment of Bendamustine and Rituximab can help people with intermediate- to high-risk mantle cell lymphoma who can't have a transplant feel better and live longer.

What this trial studies

This multicenter, open-label, randomized controlled trial evaluates the efficacy and safety of Orelabrutinib in combination with Bendamustine and Rituximab compared to Bendamustine and Rituximab alone in patients with intermediate- to high-risk mantle cell lymphoma who are not eligible for transplantation. The primary goal is to assess the complete response rate during the induction phase, while secondary objectives include progression-free survival, overall survival, and safety. Additionally, the study will explore the correlation between tumor biomarkers and treatment efficacy.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 with untreated mantle cell lymphoma and specific high-risk factors who are not suitable for autologous stem cell transplantation.

Not a fit: Patients with low-risk mantle cell lymphoma or those who have received prior treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment combination could improve response rates and survival outcomes for patients with mantle cell lymphoma.

How similar studies have performed: Other studies have shown promising results with similar treatment combinations in hematologic malignancies, suggesting potential for success in this approach.
