What is the purpose of this trial?

This trial examines a new treatment, JZP898 (an experimental treatment), both alone and with pembrolizumab, for individuals with advanced or metastatic solid tumors. The researchers aim to determine the safety of these treatments and their effects on cancer. It targets adults who have previously tried other cancer treatments without success, including those with lung cancer, melanoma, or certain other types of cancer. Participants must have a solid tumor diagnosis and have experienced cancer progression after prior therapies. As a Phase 1 trial, this research focuses on understanding how the treatment 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 requires that you stop taking any anticancer therapy at least 4 weeks or 5 half-lives (whichever is shorter) before starting the study drug. Other medications are not specifically mentioned, so it's best to discuss with the trial team.

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

Research has shown that JZP898 is still under study to determine its safety in humans. This early trial aims to assess how well people tolerate JZP898, both alone and with pembrolizumab. Pembrolizumab, already approved by the FDA for certain cancers, is known to be safe.

For JZP898, the study seeks to identify a safe dose and monitor for any side effects that might limit dose escalation. Since this is the first human trial of JZP898, information on human reactions is limited. However, understanding dose tolerances is a key goal of this research.

The safety of combining JZP898 with pembrolizumab is also under investigation in these early trials. Given pembrolizumab's established safety, any new side effects would likely result from JZP898. Yet, because this is JZP898's first human trial, its specific effects remain unknown.

In summary, while pembrolizumab has a proven safety record, JZP898 is still being evaluated. Participants in these trials help researchers learn about JZP898's safety and its potential interaction with pembrolizumab. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about JZP898 because it offers a new approach to tackling advanced cancers. Unlike the standard treatments like chemotherapy and targeted therapies, JZP898 is designed to work in conjunction with pembrolizumab, an immunotherapy that helps the immune system recognize and fight cancer cells more effectively. This combination could potentially enhance the immune response against cancer cells, offering a fresh line of attack. Moreover, JZP898 might provide a new mechanism of action, which could be particularly beneficial for patients who have not responded to existing therapies.

What evidence suggests that this trial's treatments could be effective for advanced cancer?

Research shows that JZP898 is a specially designed drug that activates in the tumor environment and can boost the immune system. Early tests suggest that JZP898 might help fight tumors, especially solid ones. In this trial, some participants will receive JZP898 as monotherapy, while others will receive it in combination with pembrolizumab. Pembrolizumab, a drug proven effective against some cancers, might further strengthen the immune system's ability to attack tumors when used with JZP898. It successfully treats cancers like melanoma and lung cancer by blocking a pathway that tumors use to hide from the immune system. The combination of these drugs aims to improve treatment results by enhancing the body's natural defenses against cancer. ^{1 2 3 4 6}

Are You a Good Fit for This Trial?

Adults over 18 with advanced or metastatic solid tumors who have tried certain treatments without success can join. They need to be fairly active and healthy (ECOG score of 0-1), not pregnant, willing to use birth control, and able to provide tumor samples. People with severe allergies, recent cancer therapies or surgeries, autoimmune diseases needing steroids, CNS tumors, lung disease requiring steroids, suicidal behavior or significant heart issues cannot participate.
