What You Need to Know Before You Apply

What is the purpose of this trial?

This phase II trial investigates the effect of nivolumab and ipilimumab when given together with short-course radiation therapy in treating patients with rectal cancer that has spread to nearby tissue or lymph nodes (locally advanced). Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving nivolumab, ipilimumab, and radiation therapy may kill more cancer cells.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, you cannot take certain medications like high-dose corticosteroids or immunosuppressive drugs within 14 days before starting the trial. It's best to discuss your specific medications with the trial team.

What are the safety concerns of using Nivolumab and Ipilimumab in cancer treatment?

Nivolumab and Ipilimumab, when used together, can cause gastrointestinal issues like diarrhea and colitis (inflammation of the colon). These treatments are linked to immune-related side effects, which can be serious, but fatal events are rare. ^{1 2 3 4 5}

How does the drug combination of nivolumab and ipilimumab differ from other treatments for rectal cancer?

The combination of nivolumab and ipilimumab is unique because it uses the body's immune system to fight cancer, unlike traditional chemotherapy. This approach, known as immunotherapy, has shown effectiveness in other cancers like melanoma and lung cancer, and it may offer a new option for rectal cancer patients, especially those with specific genetic markers. ^{6 7 8 9 10}

What data supports the effectiveness of the drug combination of Nivolumab and Ipilimumab for rectal cancer?

Research shows that the combination of Nivolumab and Ipilimumab has been effective in treating other types of cancer, such as advanced non-small cell lung cancer and metastatic colorectal cancer, by improving survival rates and achieving higher response rates compared to using Nivolumab alone. ^{6 10 11 12 13}

In a study of 274 elderly patients with advanced melanoma, the risk of developing colitis was similar for those treated with anti-CTLA4 (ipilimumab) and anti-PD1 (nivolumab or pembrolizumab) therapies.

However, when considering patients across all stages of melanoma, anti-PD1 treatment was associated with a significantly lower risk of colitis compared to anti-CTLA4, suggesting a safer profile for anti-PD1 in this broader patient population.

In a meta-analysis of clinical trials, PD-1 inhibitors (like nivolumab and pembrolizumab) were found to have a higher incidence of colitis compared to PD-L1 inhibitors (like atezolizumab and durvalumab), with rates of 1.49% for all grade colitis and 0.85% for grade 3-4 colitis.

The analysis indicated that the relative risk of developing colitis with PD-1 inhibitors was significantly higher (1.80 for all grade colitis and 2.52 for grade 3-4 colitis), suggesting that patients receiving PD-1 inhibitors may need closer monitoring for this adverse effect.
