GS-5319 for Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new drug, GS-5319, to determine the best dose and assess its safety for people with advanced solid tumors. The study targets tumors lacking a specific enzyme, methylthioadenosine phosphorylase (MTAP), which normally aids cell growth. Participants should have a solid tumor unresponsive to standard treatments or be unable to use those treatments. The trial examines how different doses of GS-5319 affect the body to identify the optimal amount for future studies. As a Phase 1 trial, this research aims to understand how the treatment works in people, offering participants the opportunity to be among the first to receive this new drug.
Do I have to stop taking my current medications for the trial?
The trial requires that you do not need ongoing therapy with any prohibited medications, but it doesn't specify which medications are prohibited. It's best to discuss your current medications with the trial team to see if they are allowed.
Is there any evidence suggesting that GS-5319 is likely to be safe for humans?
Research shows that GS-5319 is currently being tested in individuals with certain solid tumors. This Phase 1 study primarily assesses the treatment's safety and tolerability. Detailed safety information remains limited as testing continues. In these early stages, researchers closely monitor any new treatment for side effects and patient responses. If deemed safe and well-tolerated, the treatment will proceed to further testing.12345
Why do researchers think this study treatment might be promising?
GS-5319 is unique because it offers a novel approach to cancer treatment by potentially targeting cancer cells more precisely than current options. Most treatments for cancer, like chemotherapy, attack rapidly dividing cells but can also harm healthy cells, leading to significant side effects. GS-5319, however, is being explored for its ability to focus more directly on cancer cells, possibly reducing collateral damage to normal cells. Researchers are excited about this treatment because it might provide a more effective and less harmful way to manage cancer, opening new doors for patient care.
What evidence suggests that GS-5319 might be an effective treatment for cancer?
Research has shown that GS-5319 targets a specific change in a gene related to the MTAP enzyme. This enzyme plays a crucial role in normal cell growth, and some solid tumors lack it. Although human data on GS-5319 remains limited, the treatment is designed to address tumors with this genetic change, potentially increasing its effectiveness for these cancers. Participants in this trial will receive GS-5319 monotherapy, either in a dose escalation phase to determine the recommended dose or in a dose expansion phase at the recommended dose. The treatment is still in early testing, so its effectiveness is not yet known. However, focusing on the MTAP deletion offers a promising approach to treating these specific tumors.12367

Are You a Good Fit for This Trial?
Adults with solid tumors that lack the MTAP enzyme due to a specific gene alteration can join this trial. They must have tried standard treatments without success, be intolerant to them, or ineligible for such therapies. Participants need normal organ function and an ECOG score of 0-1, indicating they are fully active or restricted in physically strenuous activity but ambulatory.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- GS-5319
Trial Overview
The study is testing GS-5319's safety and tolerability in adults with MTAP-deleted advanced solid tumors. It aims to find the highest dose patients can take without serious side effects (MTD/MAD) and suggest a dose for further studies (RDE).
How Is the Trial Designed?

Treatment groups
Experimental Treatment
Participants will be enrolled in different cohorts based on the selected indications to receive GS-5319 monotherapy at the recommended dose during the monotherapy dose expansion phase.
Participants will receive escalating doses of GS-5319 monotherapy, until disease progression, or until the participants meets other study drug discontinuation criteria as specified in protocol or up to 105 weeks, whichever occurs first to determine the recommended dose for dose expansion phase.
