What this Trial Is About

Researchers are evaluating oral ABSK021 in patients with advanced solid tumors to determine its safety, tolerability, and the recommended dose for further studies. This phase 1 open-label trial also aims to assess preliminary antitumor activity in these patients. The study includes patients whose tumors have progressed after standard treatment or who have no available standard therapy. Specific focus is also given to patients with tenosynovial giant cell tumor (TGCT). The study begins with a dose escalation phase where patients receive a single oral dose of ABSK021 followed by a 3-day break to assess safety and pharmacokinetics. After this run-in, patients take ABSK021 once daily in repeated 28-day cycles. The dose increases following "3+3" escalation rules until the maximum tolerated dose or recommended dose of expansion is found. An expansion phase will then further evaluate safety and tolerability at the recommended dose in selected tumor types. Participants will be monitored for dose-limiting toxicities and adverse events throughout the study, with the primary safety assessment at the end of the first 28-day cycle and ongoing evaluation for about 6 months. Researchers will also measure tumor progression, duration of response, disease control, and pharmacokinetic parameters such as peak concentration and half-life. Patients will undergo MRI scans, organ function tests, and performance status evaluations to track treatment effects and safety during the trial, which will continue until study completion or progression.

  • ECOG performance status of 0 or 1
  • Life expectancy of at least 3 months
  • Adequate organ and bone marrow function
  • For patients with tenosynovial giant cell tumor (TGCT), diagnosis confirmed by pathology with locally advanced disease where surgery would cause severe morbidity
