Study of GS-9911 With or Without Antibody Treatment for Adults With Solid Tumors
- Registration Number
- NCT06082960
- Lead Sponsor
- Gilead Sciences
- Brief Summary
The main goal of this first in human (FIH) study is to learn about the safety and dosing of GS-9911 when given alone or in combination with an anti-programmed cell death protein 1 (PD-1) monoclonal antibody in participants with advanced solid tumors.
The primary objectives of this study are to:
* Assess the safety and tolerability of GS-9911 as monotherapy and in combination with an anti-PD-1 monoclonal antibody in participants with advanced solid tumors
* Identify the maximum tolerated dose (MTD)/maximum administered dose (MAD) and the recommended dose for expansion (RDE) of GS-9911 as monotherapy and in combination with an anti-PD-1 monoclonal antibody in participants with advanced solid tumors

- Primary Outcome Measures
Name Time Method Percentage of Participants With Treatment-emergent Adverse Events First dose date up to 90 days post last dose (up to 105 weeks) Percentage of Participants With Treatment-emergent Serious Adverse Events First dose date up to 90 days post last dose (up to 105 weeks) Percentage of Participants Experiencing any Dose-limiting Toxicities (DLTs) in Dose-escalation Cohorts First dose date up to 3 weeks
- Secondary Outcome Measures
Name Time Method Plasma Concentration of GS-9911 Predose up to end of treatment (up to 105 weeks) Pharmacokinetic (PK) Parameter: Cmax of GS-9911 Predose up to end of treatment (up to 105 weeks) Cmax is defined the maximum observed plasma drug concentration.
PK Parameter: Tmax of GS-9911 Predose up to end of treatment (up to 105 weeks) Tmax is defined as the time to maximum observed concentration.
Area Under the Concentration-Time Curve (AUC) of GS-9911 Predose up to end of treatment (up to 105 weeks) AUC is defined as the area under the concentration versus time curve.
