CCS1477 for Solid Cancers
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new treatment called CCS1477 (also known as Inobrodib) to determine its safety and effectiveness for people with certain advanced cancers. The trial targets patients with metastatic prostate cancer, breast cancer, lung cancer, or other advanced solid tumors. It includes various groups, with some patients receiving CCS1477 alone and others combining it with existing drugs like abiraterone or enzalutamide. Eligible participants have advanced cancer that hasn't responded well to treatments like abiraterone or enzalutamide. As a Phase 1 trial, this research aims to understand how the treatment works in people, offering participants the opportunity to be among the first to receive this new treatment.
Will I have to stop taking my current medications?
You may need to stop taking certain medications before joining the trial. Specifically, you must stop taking statins and any strong inhibitors or inducers of CYP3A4. If you are on chemotherapy, investigational agents, or other anti-cancer drugs, you need to stop them at least 14 days before the trial starts.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that CCS1477 has been tested in over 400 patients and is safe and well-tolerated. This treatment is being combined with other drugs for various cancer types. For instance, studies indicate that combining it with abiraterone acetate and enzalutamide in patients with advanced prostate cancer is generally safe.
Darolutamide also maintains a good safety record for these prostate cancer patients. Olaparib, another drug combined with CCS1477, has been studied for safety in patients with specific genetic backgrounds. When CCS1477 is used with atezolizumab for lung cancer, some immune-related side effects have been noted, but most were manageable.
Overall, these combinations remain under study to confirm their safety, but current data suggest they are well-tolerated. Prospective participants should consider these findings and discuss any concerns with their healthcare provider.12345Why are researchers excited about this trial's treatments?
CCS1477 is unique because it targets the p300/CBP proteins, which play a crucial role in cancer cell growth and survival, offering a new mechanism of action compared to standard treatments like hormone therapies or chemotherapy. Researchers are excited about CCS1477 because it can be combined with existing drugs like abiraterone, enzalutamide, darolutamide, and olaparib, potentially enhancing their effectiveness against metastatic castration-resistant prostate cancer (mCRPC) and other solid tumors. Unlike current treatments that primarily focus on hormone pathways or DNA damage response separately, CCS1477 may provide a more comprehensive approach by interfering with cancer cell signaling and growth regulation.
What evidence suggests that this trial's treatments could be effective for solid cancers?
Research has shown that CCS1477 may help treat castration-resistant prostate cancer (CRPC) by targeting proteins called p300/CBP, which aid cancer cell growth. Studies have found that CCS1477 can reduce levels of KLK3, a marker linked to prostate cancer, and manage important cancer-related indicators in CRPC. In this trial, some participants will receive CCS1477 with drugs like abiraterone, enzalutamide, or darolutamide, potentially enhancing its effectiveness by blocking pathways cancer cells use to survive. Other participants will receive CCS1477 combined with olaparib, which is under study for its potential effectiveness in treating prostate and breast cancer, especially when these cancers have certain genetic changes. Additionally, the combination of CCS1477 with atezolizumab (an immune therapy) is being explored for non-small cell lung cancer, as it might enhance the immune system's ability to fight cancer cells. Overall, CCS1477 targets key cancer processes, and early evidence suggests it could effectively treat several types of advanced cancers.678910

Are You a Good Fit for This Trial?
This trial is for adults with advanced prostate, breast, non-small cell lung cancer or solid tumors. Participants must have specific genetic markers indicating a potential response to treatment and meet health criteria like good organ function and performance status. They should not have severe diseases, unresolved toxicities from past therapies, or be taking certain drugs that could interfere with the study.Inclusion Criteria
