Summary

In this study, the safety and tolerability of GNC-038 in participants with recurrent or refractory Non-Hodgkin lymphoma will be investigated to assess the dose-limiting toxicity (DLT), maximum tolerated dose (MTD) or maximum administered dose (MAD) for MTD is not reached of GNC-038. The recommended dose for future clinical study will also be determined.
