What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to test a new cancer treatment called CTX-10726. It targets individuals whose cancer has spread or cannot be surgically removed and who have not responded to standard treatments. The trial will examine how different doses of CTX-10726 perform in various groups. Individuals with advanced kidney, liver, stomach, or endometrial cancers that have progressed after previous treatments may be suitable candidates for this trial. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, providing participants the opportunity to be among the first to receive this new treatment.

Do I need to stop my current medications for the trial?

The trial protocol does not specify if you need to stop taking your current medications. However, certain medications like immunomodulatory drugs and major surgical treatments must not be taken shortly before the trial. It's best to discuss your specific medications with the trial team.

Is there any evidence suggesting that CTX-10726 is likely to be safe for humans?

Research has shown that CTX-10726 is being tested for safety in treating advanced cancers. This is a Phase 1 trial, marking the first time the drug is tried in humans. The goal is to assess how well people tolerate the drug and to identify any side effects.

Previously, CTX-10726 was tested in labs and on animals, where it showed promise in fighting tumors. However, results from human trials are not yet available. In this phase, researchers focus on determining a safe dose and identifying any early side effects. The trial is carefully designed to monitor participants' reactions to the treatment.12345

Why do researchers think this study treatment might be promising?

Unlike the standard treatments for cancer, which often include chemotherapy, radiation, or surgery, CTX-10726 is unique because it targets cancer cells in a new way. Researchers are excited about CTX-10726 because it works by specifically interfering with certain pathways that cancer cells use to grow and divide, potentially leading to fewer side effects compared to conventional therapies. Additionally, the drug is being tested in different dosing strategies to optimize its effectiveness, which could mean more personalized treatment options for patients. This fresh approach offers hope for more effective and tolerable cancer treatments in the future.

What evidence suggests that CTX-10726 might be an effective treatment for cancer?

Research has shown that CTX-10726 delivers promising results in controlling tumor growth. Early studies demonstrated that it outperformed standard treatments by inhibiting the formation of blood vessels necessary for tumor growth and blocking PD-1, a protein that allows cancer to evade the immune system. It proved particularly effective in controlling tumors across various cancer types, including lung cancer. The drug targets several pathways, potentially making it effective against a range of solid tumors. These early findings suggest that CTX-10726 could be a strong option for cancer treatment. Participants in this trial will receive CTX-10726 in either a dose escalation or dose expansion cohort to further evaluate its effectiveness and safety.12346

Are You a Good Fit for This Trial?

This trial is for adults (18+) with advanced or metastatic endometrial, kidney, gastroesophageal, or liver cancer who have already tried certain standard treatments like immunotherapy and tyrosine kinase inhibitors. Patients must be in stable condition and not have had recent major surgery or immune-boosting drugs.

Inclusion Criteria

I have not taken immune-boosting drugs in the past 2 weeks or had major surgery in 3 weeks.
I have been diagnosed with hepatocellular carcinoma (HCC).
I have had at least 2 doses of PD-1/PD-L1 treatment and my cancer has worsened.
