About this trial

The main goal of this first in human (FIH) study is to learn about the safety and dosing of GS-0201 when given alone or in combination with sacituzumab govitecan (SG) in participants with advanced solid tumors.

The primary objectives of this study are to:

* To assess the safety and tolerability of GS-0201 as monotherapy and in combination with SG in participants with selected advanced solid tumors * To identify the maximum tolerated dose (MTD) and/or the recommended Phase 2 dose (RP2D) of GS-0201 as monotherapy and the MTD and/or the RP2D and dosing schedule of GS-0201 in combination with SG in participants with selected advanced solid tumors

Trial outcomes

Primary outcomes

1

The Number of Participants with Dose Limiting Toxicities (DLTs) During Dose Escalation

DLTs are defined as any of the following treatment-emergent adverse events (AEs) regardless of attribution (graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0), unless clearly related to an underlying disease or extraneous causes, with onset within the DLT-evaluation period for the corresponding dose.

Time frame
First dose up to 30 days post last dose (Up to approximately 109 weeks).
2

The Percentage of Participants with Adverse Events (AEs) and Serious Adverse Events (SAEs)

Time frame
First dose up to 30 days post last dose (Up to approximately 109 weeks).
3

The Incidence of Laboratory Abnormalities

Time frame
First dose up to 30 days post last dose (Up to approximately 109 weeks).

Secondary outcomes

1

Pharmacokinetic (PK) Parameter: Area Under the Concentration (AUC)0-24 of GS-0201

AUC0-24 is defined as the concentration of drug over time between time 0 and time 24 hours.

Time frame
Predose and postdose up to end of treatment (up to 105 weeks)
2

PK Parameter: Cmax of GS-0201

Cmax is defined as the maximum observed drug concentration.

Time frame
Predose and postdose up to end of treatment (up to 105 weeks)
3

PK Parameter: Tmax of GS-0201

Tmax is defined as the time to maximum observed concentration.

Time frame
Predose and postdose up to end of treatment (up to 105 weeks)
4

PK Parameter: AUC0-168 of SG (Parts C and D only)

AUC0-168 is defined as the concentration of drug over time between time 0 and time 168 hours.

Time frame
Predose and postdose up to end of treatment (up to 105 weeks)
