A Phase 1, Open-Label Study of ABSK061 to Assess Safety, Tolerability, and Pharmacokinetics in Patients With Advanced Solid Tumors
Abbisko Therapeutics Co, Ltd
Summary
This is an open-label phase 1 study with expansion. The study will start with a dose escalation of single-agent ABSK061 administered in repeated 28-day cycles in patients with advanced solid tumors to evaluate safety and tolerability. The expansion part will investigate oral ABSK061 at the recommended dose for expansion (RDE) to further evaluate safety and tolerability among selected tumor types. Preliminary antitumor activity will also be assessed.
Description
Escalation Part: Dose escalation of oral ABSK061 will be guided by the Bayesian optimal interval (BOIN) design based on safety data collected until a maximum tolerated dose (MTD) or maximum administered dose (MAD) has been identified. During the dose escalation part of the study, patients will receive a single dose of ABSK061 on C1D1 only, and then BID dosing for the rest of the days of cycle 1 and in the subsequent cycles. If the actual elimination half-life of ABSK061 is greatly exceeding that predicted, a run-in period with a single-dose and a longer drug-free observation period could be p…
