Orelabrutinib with rituximab and optional autologous stem cell transplant for mantle cell lymphoma

Official title: A Prospective, Multicenter, Open-Label Clinical Study of Orelabrutinib in Combination With Rituximab With Optional Autologous Hematopoietic Stem Cell Transplantation in Treatment-Naive, Non-High-Risk Mantle Cell Lymphoma (MCL)

Run by Ruijin Hospital · NCT07199296 · Data updated 2026-11-12

This phase 2 trial tests whether adding the oral BTK inhibitor orelabrutinib to rituximab, with optional autologous stem cell transplant and orelabrutinib maintenance, works and is safe for people with newly diagnosed non-high-risk mantle cell lymphoma.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are treatment-naïve patients older than 14 with biopsy-confirmed, measurable stage II–IV non-high-risk mantle cell lymphoma, adequate blood, liver and kidney function, and expected survival beyond 12 weeks.

Probably not a fit

Patients with high-risk MCL features, prior systemic therapy, significant organ dysfunction, or inability to attend site visits or undergo transplant procedures are unlikely to benefit or may be excluded.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This multicenter, open-label phase 2 trial gives treatment-naïve patients orelabrutinib plus rituximab during an induction phase; responders may proceed to optional autologous hematopoietic stem cell transplantation followed by orelabrutinib maintenance. The primary endpoint is the complete response (CR) rate during induction, with secondary endpoints including progression-free survival, overall survival, objective response rate, and safety. Conditioning with BEAM is used for patients who undergo transplant. Exploratory biomarker analyses will examine correlations between tumor markers and treatment efficacy.

Why it matters

Potential benefit: If successful, this approach could raise complete response rates and prolong time without progression while offering an oral maintenance option that may delay or reduce need for more intensive therapies.

How similar studies have gone: Other studies combining BTK inhibitors (like ibrutinib) with anti-CD20 antibodies have shown promising activity in MCL, but orelabrutinib-specific data and this exact combination with optional transplant remain relatively limited.
