Detailed Description
Diffuse large B-cell lymphoma as the most common lymphoma, is heterogeneous. R-CHOP is the standard care in front-line DLBCL treatment. However, there are still about 40% of the DLBCL patients treated with R-CHOP relapse or respond poorly.
There are 20%-30% DLBCL patients having BCL2 and MYC co-expression, which are more common in activated B -cell-like(ABC)-DLBCL. Previous study showed that patients with co-expression of BCL2 and MYC by immunohistochemistry (IHC) have a worse outcome with R-CHOP.
Efficacy results from Studies PCYC-04753 and PCYC-1106-CA demonstrate that BTK inhibitor ibrutinib has some activity as a single agent in subjects with relapsed or refractory DLBCL, with possible lower response rates in subjects with the germinal center B-cell-like (GCB)subtype.
In post hoc of PHEONIX study, non-GCB subgroup pts with MYC-high + BCL2-high had better event free survival (EFS )(HR 0.648; 95% confidence interval (CI), 0.423-0.993; p = 0.045) with ibrutinib + R-CHOP versus placebo + R-CHOP.
Zanubrutinib is a highly specific, potent new BTK inhibitor, with minimal off-target inhibition of other kinases, and is associated with better tolerability, compared with ibrutinib. A post hoc analysis on 4 studies found that Patients with MYC and BCL2 double-expressor DLBCL resulted in objective response rate(ORR)of 61% and progression free survival (PFS) of 5.4m when treated with zanubrutinib. However, it is still unknown the benefit of zanubrutinib and RCHOP combination therapy followed by zanubrutinib maintenance in non-GCB DLBCL patients with co-expression of BCL2 and MYC.
This is a single-arm, phase II study, to evaluate the efficacy and safety of zanubrutinib in combination with R-CHOP followed by zanubrutinib maintenance in newly diagnosed non-GCB subtype of DLBCL patients with MYC-high + BCL2-high selected by IHC.
The study will include a Screening Phase, Combination Treatment Phase, Maintenance phase and a Post Treatment Follow-up Phase.
