Advanced Solid Tumors
Conditions
Brief summary
The goal of this clinical study is to learn more about the study drug GS-2426, and how safe and tolerable it is in participants with advanced methylthioadenosine phosphorylase (MTAP)-deleted solid tumors. The primary objective of this study is to evaluate the safety and tolerability of GS-2426 in participants with MTAP-deleted advanced solid tumors and to determine the maximum tolerated dose (MTD)/maximum administered dose (MAD) and the recommended phase II dose (RP2D).

Secondary
| Measure | Time frame | Description |
|---|---|---|
| Plasma Concentration of GS-2426 | Predose and postdose up to end of treatment (up to 105 weeks) | — |
| Pharmacokinetic (PK) Parameter: AUC0-24h of GS-2426 | Predose and postdose up to end of treatment (up to 105 weeks) | AUC0-24h is defined as the area under concentration versus time from 0 to 24 hours. |
| PK Parameters: Cmax of GS-2426 | Predose and postdose up to end of treatment (up to 105 weeks) | Cmax is defined as the maximum observed plasma drug concentration. |
| PK Parameters: Tmax of GS-2426 | Predose and postdose up to end of treatment (up to 105 weeks) | Tmax is defined as the time to peak plasma drug concentration of GS-2426. |
