RLY-4008 for Bile Duct Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores a new treatment called RLY-4008, an experimental drug, to assess its safety and effectiveness for people with bile duct cancer (cholangiocarcinoma) and other solid tumors. The study will test different doses and examine the treatment's impact on cancer. It targets individuals whose cancer cannot be surgically removed or has spread, and who have specific changes in their FGFR2 gene. Those who have tried other treatments without success or cannot take standard therapies might be suitable candidates for this trial. As a Phase 1, Phase 2 trial, this research aims to understand how the treatment works in people and measure its effectiveness in an initial, smaller group, offering a chance to be among the first to benefit from this new approach.
Will I have to stop taking my current medications?
The trial information does not specify if you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
Is there any evidence suggesting that RLY-4008 is likely to be safe for humans?
Research has shown that RLY-4008, a new treatment for bile duct cancer, was generally well-tolerated in earlier studies. Patients who received RLY-4008 experienced promising results with manageable side effects. At the tested doses, the treatment shrank tumors without causing major changes in important blood levels, such as phosphate. Additionally, RLY-4008 demonstrated good behavior in the body, with higher doses proving more than 90% effective in targeting the cancer. Overall, these findings suggest that RLY-4008 could be a safe option for people with this type of cancer.12345
Why do researchers think this study treatment might be promising?
RLY-4008 is unique because it specifically targets FGFR2, a protein often overactive in bile duct cancer. Unlike traditional chemotherapy and targeted therapies that can affect a wide range of cells, RLY-4008 precisely inhibits the FGFR2 pathway, potentially leading to fewer side effects and more effective treatment. Researchers are excited about RLY-4008 because it offers a promising new approach by honing in on a specific genetic alteration associated with this cancer, which could improve outcomes for patients who haven't had success with current treatments.
What evidence suggests that RLY-4008 might be an effective treatment for bile duct cancer?
Research has shown that RLY-4008, the investigational treatment in this trial, holds promise for treating bile duct cancer, particularly in patients with FGFR2 changes. Studies have found that it effectively blocks FGFR2, which is linked to tumor reduction. In patients who had not previously used FGFR inhibitors, there was a strong response against the tumor. Specifically, one study reported an overall response rate of 88%, with some patients experiencing significant tumor shrinkage. This suggests RLY-4008 could be a highly effective option for people with this type of cancer.23467
Are You a Good Fit for This Trial?
This trial is for adults with advanced bile duct cancer or other solid tumors that have specific genetic changes in FGFR2. They should be able to perform daily activities with little help (ECOG 0-1) and may have had previous treatments, but not a drug targeting FGFR2. People can't join if they have active infections like HIV/HBV/HCV, serious heart issues, eye problems from similar drugs, poor organ function, or certain electrical heart disturbances.Inclusion Criteria

- RLY-4008
Trial Overview
RLY-4008 is being tested in patients with intrahepatic cholangiocarcinoma (ICC) and other solid tumors that haven't responded well to standard treatments. The study has three parts: finding the right dose of RLY-4008 (dose escalation), seeing how well it works at this dose (dose expansion), and long-term follow-up (extension).
