clinical trial of hg146 administered to subjects with advanced solid tumors or lymphoma

Conditions: Solid Tumor; Lymphoma

Summary: this is a phase i, open-label, repeat-dose, non-randomized, multicenter study to evaluate the safety, tolerability, and preliminary clinical activity and establish a recommended dose of hg146 administered orally (po) alone (part 1) or co-administered (part 2) with pd-（l）1 inhibitor in subjects with refractory/relapsed solid tumors or lymphoma. part 1 consists of a dose escalation phae,part2 consists of a dose escalation phase and a cohort expansion phase. in part 1, escalating doses of hg146 will be evaluated as guided by the "3+3" approach. in part 2a, escalating doses of hg146 in combination with pd-(l)1 inhibitor will be evaluated as guided by the "3+3" approach. in part 2b, subjects will receive a single dose level of hg146 as identified based on data from part 2, in combination with pd-(l)1 inhibitor . a total of approximately 96 subjects will be enrolled in this study, approximately 36 for dose escalation cohorts, and approximately 60 in the expansion cohorts.
