What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new cancer treatment, GSK3745417, for individuals with solid tumors unresponsive to standard treatments. The researchers aim to determine the safety and efficacy of this drug alone and in combination with dostarlimab. Participants must have a solid tumor that has recurred or does not respond to existing therapies and must provide a fresh biopsy for the study. As a Phase 1 trial, this research seeks to understand how the treatment works in people, offering participants the opportunity to be among the first to receive this new therapy.

Do I have to stop taking my current medications for the trial?

The trial does not specify if you need to stop taking your current medications. However, you cannot participate if you require systemic immunosuppressive treatment or have taken certain cancer therapies recently. It's best to discuss your specific medications with the trial team.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that GSK3745417 is generally safe for patients, meaning most people can take it without serious problems. In studies, it has shown promise in helping the immune system fight tumors.

When combined with dostarlimab, research suggests it can effectively control cancer. Dostarlimab has been used in other treatments and has slowed cancer growth. This suggests that using them together might be safe, based on past experiences with these drugs.

Since this trial is in an early phase, the main focus is on assessing the treatment's safety for people. At this stage, researchers closely monitor the new treatment to evaluate how well people tolerate it and to determine the best dose. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about GSK3745417 because it offers a novel approach to cancer treatment. Unlike traditional therapies such as chemotherapy and radiation, which broadly target rapidly dividing cells, GSK3745417 is designed to specifically target and activate the immune system to attack cancer cells. This treatment works by modulating immune pathways, potentially leading to fewer side effects and more precise targeting of cancerous cells. Additionally, when combined with dostarlimab, an immune checkpoint inhibitor, GSK3745417 may enhance the body's natural ability to fight cancer, offering hope for more effective and personalized treatment options.

What evidence suggests that GSK3745417 might be an effective treatment for cancer?

Research has shown that GSK3745417 could be a promising cancer treatment because it helps the immune system fight tumors. Early data suggests it increases proinflammatory cytokines, which can help control tumor growth. In this trial, some participants will receive GSK3745417 alone, while others will receive it with dostarlimab, an existing cancer treatment. Dostarlimab has significantly improved survival rates in some cancers, such as endometrial cancer. This combination aims to leverage the strengths of both treatments to potentially provide a stronger defense against cancer. ^{1 2 5 6 7}

What Are the Treatments Tested in This Trial?

Interventions

• GSK3745417

Trial Overview The study is testing GSK3745417 alone (Part 1A) or combined with dostarlimab (Part 2A) in patients with stubborn solid tumors. It's in the first phase where they're figuring out safe doses and checking how well it works by gradually increasing the dose.

How Is the Trial Designed?

Group I: Part 2A: Participants receiving GSK3745417 + dostarlimab, Dose escalation Cohort Experimental Treatment 2 Interventions

Group II: Part 1A: Participants receiving GSK3745417, Dose-escalation Cohort Experimental Treatment 1 Intervention
