Nivolumab + Ipilimumab for Colorectal Cancer
(CheckMate 8HW Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests new treatments for colorectal cancer that has spread and is difficult to remove surgically. Researchers aim to evaluate the effectiveness of two treatments, nivolumab alone and nivolumab with ipilimumab, compared to standard chemotherapy. The goal is to determine if these treatments can extend patient survival and slow cancer progression. Individuals with specific tumor types, such as MSI-H (a genetic marker) or dMMR (a cellular repair issue), might be suitable candidates. Those who have tried other treatments without success may find this trial beneficial. As a Phase 3 trial, it represents the final step before FDA approval, providing access to potentially groundbreaking treatments.
Do I have to stop taking my current medications for the trial?
The trial protocol does not specify whether you need to stop taking your current medications. Please consult with the trial coordinators for more details.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research shows that the FDA has approved nivolumab, both alone and with ipilimumab, for treating advanced colorectal cancer with specific genetic traits (MSI-H/dMMR). This approval confirms its safety for this use. Earlier studies found that using nivolumab and ipilimumab together was generally safe, with the most common serious side effects being diarrhea and increased enzyme levels, occurring in 2% or more of patients.
Nivolumab alone has also undergone extensive study. Although serious side effects like diarrhea, pneumonia, and urinary tract infections were reported, they remained uncommon. The treatments have demonstrated lasting positive effects and high survival rates in patients, suggesting they are generally well-tolerated, especially given their FDA approval for similar conditions.12345Why are researchers excited about this trial's treatments?
Researchers are excited about the combination of Nivolumab and Ipilimumab for colorectal cancer because it offers a novel approach to treating the disease. Unlike traditional chemotherapy, which directly attacks cancer cells, these drugs work by enhancing the body's immune system to recognize and destroy cancer cells. Nivolumab and Ipilimumab are immune checkpoint inhibitors, targeting specific proteins (PD-1 and CTLA-4) that can prevent immune cells from attacking cancer effectively. This mechanism has the potential to offer a more targeted and possibly more effective treatment option with a different side effect profile compared to standard chemotherapy regimens like Fluorouracil and Oxaliplatin.
What evidence suggests that this trial's treatments could be effective for metastatic colorectal cancer?
Research has shown that nivolumab, which participants in this trial may receive as monotherapy in Arm A, can effectively treat metastatic colorectal cancer (mCRC) in patients with certain genetic traits (MSI-H/dMMR). Studies have found that many patients respond well, with their cancer remaining stable for a significant time.
In Arm B of this trial, participants will receive a combination of nivolumab and ipilimumab. This combination treatment reduced the risk of cancer progression or death by 38% compared to nivolumab alone. After three years, about 68% of patients who received this combination remained alive without their cancer worsening. This suggests that the combination might be more effective in prolonging life and controlling the disease.25678Who Is on the Research Team?

Are You a Good Fit for This Trial?
This trial is for adults with a specific type of advanced colorectal cancer that's not suitable for surgery. Participants must have tumors with high microsatellite instability or mismatch repair deficiency, and be in good physical condition (ECOG ≤1). People who've had certain immune diseases, lung conditions, or are HIV positive cannot join.Inclusion Criteria
