Pirtobrutinib+Pola-R-CHP for Newly Diagnosed Non-GCB DLBCL

This is a single-arm, open-label, multicenter clinical study evaluating the efficacy and safety of pirtobrutinib combined with Pola-R-CHP in previously untreated Non-GCB DLBCL. PET/CT assessment will be performed after 3 cycles of combination therapy. Patients achieving CR/PR will continue treatment for another 3 cycles, while those with PD/SD will be discontinued from the study. Patients achieving CR/PR after 6 cycles of treatment will undergo follow-up with PET/CT or contrast-enhanced CT every 3 months during the first year and every 6 months thereafter, until disease progression, death, withdrawal of informed consent, or study completion, whichever occurs first.
