Trial Summary

Will I have to stop taking my current medications?

The trial requires that you stop any previous drug therapy at least 2 weeks before starting the study treatment. Additionally, you cannot be on strong CYP3A4 inhibitors or inducers, and certain other medications may also need to be stopped. It's best to discuss your current medications with the trial team to see if any changes are needed.

What data supports the effectiveness of the drug combination of regorafenib and nivolumab for gastroesophageal cancer?

Research shows that regorafenib, when combined with nivolumab, has shown promising response rates in advanced gastroesophageal cancer, and regorafenib alone has been effective in prolonging survival in other cancers like colorectal cancer.¹ ² ³ ⁴ ⁵

Is the combination of Regorafenib and Nivolumab safe for treating gastroesophageal cancer?

Regorafenib and Nivolumab have been studied for safety in various cancers. Regorafenib can cause side effects like skin reactions, high blood pressure, diarrhea, and fatigue, but these are usually manageable with dose adjustments. Nivolumab, when added to chemotherapy, has been shown to improve survival in advanced gastroesophageal cancer, and its safety profile is generally considered acceptable.¹ ⁴ ⁵ ⁶ ⁷

How is the drug combination of Nivolumab and Regorafenib unique for treating gastroesophageal cancer?

The combination of Nivolumab and Regorafenib is unique because it pairs an immune checkpoint inhibitor (Nivolumab) with a multi-targeted kinase inhibitor (Regorafenib), potentially enhancing the body's immune response against cancer cells while also inhibiting tumor growth pathways. This approach is novel for gastroesophageal cancer, where standard treatments are limited after initial therapies.¹ ³ ⁴ ⁵ ⁸

What is the purpose of this trial?

To determine if the regorafenib and nivolumab combination (RegoNivo) improves overall survival compared with current standard chemotherapy options in refractory AGOC.

Trial Overview The study is testing whether a combination of Regorafenib and Nivolumab (RegoNivo) can extend life more effectively than standard chemotherapy options for patients with refractory AGOC. Patients will be randomly assigned to receive either the new drug combo or one of several standard chemo drugs like Docetaxel.

Findings from Research

In a phase 2 trial involving 39 patients with advanced HER2-negative oesophagogastric adenocarcinoma, the combination of regorafenib, nivolumab, and chemotherapy resulted in 71% of patients being progression-free at 6 months, indicating promising efficacy.

The treatment was generally safe, with the most common adverse effects being fatigue and decreased neutrophil count, and no treatment-related deaths reported, suggesting that this combination could be a viable option for further investigation.

Regorafenib is an oral multikinase inhibitor approved for treating pretreated metastatic colorectal cancer and gastrointestinal stromal tumors, showing antiangiogenic and antiproliferative effects, based on data from phase III studies.

Currently, regorafenib is being investigated in phase III trials for hepatocellular carcinoma and in several phase II studies for other gastrointestinal tumors, indicating its potential for broader applications in cancer treatment.

Regorafenib significantly improves overall survival by up to 2.5 months and progression-free survival by up to 1.5 months in patients with metastatic colorectal cancer (mCRC) who have not responded to standard therapies, based on phase 3 studies.

The treatment is generally well-tolerated, with most side effects being mild to moderate, and it does not negatively impact health-related quality of life compared to placebo.
