This is a phase I, open-label, multi-center study of KFA115 as a single agent and in combination with tislelizumab. The study consists of a dose escalation part, followed by dose expansion part(s) for single-agent KFA115 and KFA115 in combination with tislelizumab. The escalation parts will characterize safety and tolerability. After the determination of the maximum tolerated dose (MTD) / recommended dose (RD), the dose expansion parts will assess the preliminary anti-tumor activity in defined patient populations and further assess the safety and tolerability at MTD/RD.
The purpose of this study is to characterize the safety and tolerability of KFA115 and KFA115 in combination with tislelizumab in patients with select advanced cancers, and to identify the maximum tolerated dose and/or recommended dose.
