Advanced Solid Tumor
Conditions
Brief summary
This is a multicenter, open-label, phase Ia study to evaluate the safety, tolerability and preliminary efficacy of ILB2109, a A2a receptor antagonist, in patients with locally advanced or metastatic solid malignancies.
Detailed description
This is a two-part study consists of dose escalation and dose expansion. The dose escalation part adopts a 3+3 protocol design and consists of 5 cohorts. Based on the data obtained from the escalation study, selected cohorts will be expanded to further investigate the safety and efficacy of the study drug. The escalation part consists of a single-dose cycle (Cycle 0) followed by multiple-dose cycles (Cycle 1 and above). Subjects will be assessed for safety and efficacy outcomes at pre-specified time points.
Interventions
ILB2109 tablets by mouth once per day at dosages prespecified by the protocol. Participants will continue treatment until the end of the study in the absence of unacceptable toxicities and confirmed disease progression.
