Overview

This is a phase 1/2 open-label study to evaluate GW5282 in combination with golidocitinib (G2 regimen) for the treatment of T-cell lymphoma. In the first phase of the study, the maximum tolerated dose will be determined through dose escalation; in the second phase, the potential therapeutic advantages of the novel combination therapy over the conventional CHOP regimen will be preliminarily assessed through a randomized controlled design.
