Valemetostat + Pembrolizumab for Lung Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to evaluate the effectiveness of combining Valemetostat Tosylate, a new potential drug, with Pembrolizumab, an immunotherapy drug, compared to using only Pembrolizumab for treating advanced non-small cell lung cancer (NSCLC) without certain genetic changes. The researchers seek to determine if the combination is more effective for individuals who have not yet received systemic treatment for their advanced lung cancer. The trial is recruiting participants with specific types of NSCLC that lack genetic changes such as EGFR, ALK, or ROS1, and whose tumors exhibit high levels of the protein PD-L1. Individuals with advanced or recurring lung cancer fitting this profile may find this trial suitable. As a Phase 1, Phase 2 trial, the research focuses on understanding the treatment's effects in people and assessing its effectiveness in an initial, smaller group.
Do I need to stop my current medications to join the trial?
The trial protocol does not specify if you need to stop taking your current medications. However, if you are on immunosuppressive therapy or high-dose steroids, you may need to adjust your treatment. 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 is examining the safety and effectiveness of using Valemetostat Tosylate with Pembrolizumab for lung cancer treatment. Earlier studies have shown that Valemetostat is generally safe when used alone for certain lung cancer types. However, specific safety information about its use with Pembrolizumab remains limited.
Pembrolizumab is a well-known cancer treatment and is usually well-tolerated. Common side effects include fatigue, rash, and diarrhea, but these are typically manageable.
As this combination treatment is still under study, researchers continue to gather safety information. Participation in this study will help researchers understand how patients handle the combination.12345Why are researchers excited about this trial's treatments?
Researchers are excited about the combination of valemetostat and pembrolizumab for lung cancer because it introduces a novel approach to treatment. Most current lung cancer treatments, like chemotherapy or traditional immunotherapies, target cancer cells directly or enhance the immune response. However, valemetostat is a dual EZH1/2 inhibitor, which means it targets specific enzymes that play a role in cancer cell growth and survival, potentially overcoming resistance seen with standard treatments. When combined with pembrolizumab, a well-known immunotherapy, this treatment aims to enhance the body's immune response against cancer cells more effectively. This unique mechanism could offer new hope for patients who don't respond well to existing treatment options.
What evidence suggests that this trial's treatments could be effective for lung cancer?
Research has shown that pembrolizumab effectively treats lung cancer, particularly in patients with specific tumor types. In this trial, some participants will receive pembrolizumab alone, while others will receive it in combination with valemetostat tosylate. Researchers are testing valemetostat tosylate with pembrolizumab to determine if it enhances the treatment's effectiveness. Early results suggest that this combination might outperform pembrolizumab alone. In other cancers, such as head and neck cancer, pembrolizumab alone has not been as successful, highlighting the need for improved treatment combinations. The combination of valemetostat and pembrolizumab aims to address these challenges by targeting cancer cells more effectively.13567
Are You a Good Fit for This Trial?
Adults diagnosed with advanced non-small cell lung cancer (NSCLC) without certain genetic changes, who haven't had systemic therapy for their condition. They must have a high PD-L1 expression and no history of smoking or be under 40 if they have squamous NSCLC. Participants need measurable disease on scans and must provide tissue samples unless prohibited by law.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- Pembrolizumab
- Valemetostat Tosylate
Trial Overview
The trial is testing Valemetostat Tosylate combined with Pembrolizumab against Pembrolizumab alone in patients with first-line NSCLC that lacks specific genomic alterations. The goal is to see if adding Valemetostat improves treatment outcomes compared to just using Pembrolizumab.
