What is the purpose of this trial?

This trial tests a new treatment called MEM-288 (an oncolytic virus) for individuals with advanced non-small cell lung cancer (NSCLC) that has progressed after standard treatments. The study aims to determine if MEM-288, when injected directly into tumors and used with the chemotherapy drug docetaxel, can activate the immune system to fight cancer. Participants will initially receive MEM-288 alone, then MEM-288 with docetaxel, or both together from the start. This trial suits those with advanced NSCLC who have accessible tumors for injection and have not succeeded with other treatments. As a Phase 1 trial, this research focuses on understanding how MEM-288 works in people, offering participants the chance to be among the first to receive this new treatment.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. However, you cannot use other anticancer agents while participating in the trial.

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

Research has shown that MEM-288, used alone or with other treatments, has been studied for safety in people with solid tumors. In these studies, researchers injected MEM-288 directly into tumors. The findings suggest that MEM-288 is generally safe and well-tolerated by patients. One study found that MEM-288 not only helped shrink tumors but also boosted the body's immune response against cancer.

When combined with nivolumab, another cancer treatment, participants did not experience unexpected severe side effects. Nivolumab is already approved for other cancer treatments, supporting its safety.

Research is ongoing for the combination of MEM-288 and docetaxel. Like nivolumab, docetaxel is a standard cancer treatment, which usually means its safety is well understood. Early studies suggest that MEM-288 can be safely used with standard treatments, but more information will come from ongoing research.

In summary, early studies indicate that MEM-288 is safe and generally well-tolerated, both alone and with other treatments. This promising data helps ensure the treatments are safe for more people in future studies. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Unlike the standard treatments for non-small cell lung cancer, like chemotherapy or targeted therapies, MEM-288 takes a novel approach by using an oncolytic virus that directly attacks cancer cells. Researchers are excited about MEM-288 because it is delivered via an intratumoral injection, allowing for precise targeting of tumors while potentially minimizing side effects. Additionally, in combination treatments, MEM-288 is paired with powerful drugs like nivolumab or docetaxel, which may enhance the immune response against cancer. This unique combination of direct tumor targeting and immune system activation offers new hope for more effective treatment outcomes.

What evidence suggests that this trial's treatments could be effective for non-small cell lung cancer?

Research has shown that MEM-288, a type of virus used to treat cancer, can directly attack cancer cells and help the immune system recognize and fight cancer. Studies have found that MEM-288 can shrink tumors and strengthen the body's immune response against them. In this trial, some participants will receive MEM-288 in combination with Nivolumab, a drug that helps the immune system target cancer. This combination has increased the number and effectiveness of T cells that kill tumors. Early research suggests this combination can safely reduce tumor size and improve the body's defenses against cancer. Additionally, another group of participants in this trial will receive MEM-288 with Docetaxel, another cancer treatment, to evaluate if they work even better together. ^{1 2 3 4 6}

In a study of 162 patients with advanced non-small-cell lung cancer (NSCLC) receiving nivolumab, an increase in the lymphocyte-to-monocyte ratio (LMR) by 10% or more after 4 weeks was linked to a higher response rate and longer survival, indicating its potential as a predictive marker for treatment efficacy.

The findings were consistent across both discovery and validation cohorts, suggesting that monitoring LMR changes could help determine whether to continue nivolumab therapy, while no similar correlation was found in patients treated with docetaxel.
