A Study of ATG-031 in Advanced Solid Tumors or B-cell Non-Hodgkin Lymphomas

This is a multicenter, open-label, Phase 1 study of ATG-031 in patients with advanced solid tumors or B-NHL. The study design includes a Dose Escalation Phase and a Dose Expansion Phase. Dose Escalation Phase: approximately 30-48 patients . Dose Expansion Phase: the number of patients enrolled will depend on the number of disease cohorts to be expanded and data observed in the Dose Escalation Phase.The Dose Escalation Phase will enroll patients with advanced solid tumors. Based on data from dose escalation (e.g., adverse events \[AEs\], dose-limiting toxicity \[DLT\], efficacy data, pharmacodynamic \[PDx\] data, or pharmacokinetic \[PK\] data), the Dose Expansion Phase will enroll patients with selected advanced solid tumors or B-NHL.
