简要总结
The primary purpose of this study is to assess the safety and tolerability of lunresertib alone and in combination with RP-3500 or in combination with Debio 0123 in patients with eligible advanced solid tumors, determine the maximum tolerated dose (MTD) and assess preliminary anti-tumor activity.
详细描述
Phase 1/1b, multi-center, open-label, dose-escalation study to:
- Evaluate the safety profile and MTD of lunresertib alone and in combination with RP-3500 or in combination with Debio 0123 when administered orally to establish the recommended Phase 2 dose and schedule
- Characterize the PK and pharmacodynamics of lunresertib alone and in combination with RP-3500 or in combination with Debio 0123
- Assess preliminary anti-tumor activity associated with lunresertib alone and in combination with RP-3500 or in combination with Debio 0123
This study was previously posted by Repare Therapeutics. In September 2025, sponsorship of the trial was transferred to Debiopharm International S.A
Expanded Access Status: There is no expanded access program available for the investigational products in this study at this time.
