Lymphoma, Solid Tumor

Brief 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.

Interventions

DRUGHG146

HG146 is available as Capsule at a unit dose strength of 5 mg and 10 mg.

DRUGPD-(L)1 antibody

PD-(L)1 Antibody is available as solution for infusion or lyophilized powder for reconstitution to be administered Q3W. It will be administered as an IV infusion for 30 minutes.
