简要总结
The primary objective of the trial is to evaluate an estimator of efficacy of the chemotherapy-light combination of glofitamab, polatuzumab vedotin and rituximab in patients with previously untreated aggressive large B-cell lymphoma not eligible for a fully dosed R-CHOP. The results shall be generated from the first 80 patients enrolled and can be used for initial effect estimation and planning of a subsequent phase III trial.
