What You Need to Know Before You Apply

What is the purpose of this trial?

A phase 2 study of regorafenib in combination with nivolumab in patients with refractory or recurrent osteosarcoma.

Will I have to stop taking my current medications?

The trial does not specify if you must stop taking your current medications. However, you cannot participate if you are using strong CYP3A4 inhibitors or inducers, or if you require oral anticoagulant therapy with oral vitamin K antagonists like warfarin.

Is the combination of Regorafenib and Nivolumab safe for humans?

Regorafenib has been studied for safety in various cancers, including colorectal, liver, and bone cancers, and is FDA-approved for some of these conditions. It has shown survival benefits and improved progression-free survival in these studies, indicating it is generally safe for human use. Nivolumab, often used in combination with other treatments, has also been evaluated for safety in different cancer types. ^{1 2 3 4 5}

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

The combination of Regorafenib and Nivolumab is unique for treating osteosarcoma because Regorafenib is an oral drug that targets multiple pathways involved in tumor growth, while Nivolumab is an immunotherapy that helps the immune system attack cancer cells. This combination aims to enhance treatment effectiveness by using both targeted therapy and immunotherapy approaches. ^{1 5 6 7 8}

What data supports the effectiveness of the drug combination Regorafenib and Nivolumab for treating osteosarcoma?

Research suggests that immune-based treatments like Nivolumab, which targets the PD-1 pathway, may improve outcomes in osteosarcoma by preventing immune escape, a process that allows cancer to grow unchecked. Additionally, studies in other cancers have shown that blocking PD-1/PD-L1 interactions can enhance the immune system's ability to fight tumors. ^{9 10 11 12 13}

Are You a Good Fit for This Trial?

This trial is for patients aged 5 and older with high-grade osteosarcoma that's come back or hasn't responded to treatment. They need measurable disease on scans, good heart and lung function, no recent major surgeries or uncontrolled diseases, and must not be pregnant. Participants should have recovered from prior treatments and agree to use birth control.

What Are the Treatments Tested in This Trial?

Interventions

• Nivolumab
• Regorafenib

Trial Overview The study tests the combination of Regorafenib (a cancer growth blocker) at different doses with Nivolumab (an immune system booster) in those whose osteosarcoma has resisted initial therapy. It aims to see if this combo can shrink tumors better than previous treatments.

Published Research Related to This Trial

In a study of 66 patients with recurrent bone tumors, regorafenib and cabozantinib showed meaningful activity, with median overall survival ranging from 8.1 to 18.2 months depending on the tumor type.

The treatment was generally well-tolerated, with 42.4% of patients requiring dose reductions due to side effects, indicating that these targeted therapies can be effective with manageable toxicity.

In a study of 72 patients with microsatellite stable metastatic colorectal cancer, regorafenib or fruquintinib combined with sintilimab showed a median progression-free survival of 4.2 months and an overall survival of 10.5 months, indicating these combinations are viable third-line treatment options.

The treatment was generally well-tolerated, with only 15.3% of patients experiencing severe adverse events, and patients without liver metastasis showed better response rates and overall survival, suggesting they may benefit more from this regimen.

Regorafenib is an oral multi-kinase inhibitor that has shown significant survival benefits in metastatic colorectal cancer and has been FDA approved for this use since 2012.

The drug also improves progression-free survival in patients with metastatic gastrointestinal stromal tumors and advanced hepatocellular carcinoma, leading to its FDA approval for these conditions as well.

Regorafenib is an effective oral multikinase inhibitor approved by the FDA for treating metastatic colorectal cancer in patients who have not responded to standard chemotherapy and other targeted therapies, showing significant efficacy compared to placebo in the CORRECT trial.

While regorafenib has a greater antiangiogenic effect than sorafenib, it is associated with common severe side effects such as hand-foot skin reactions, diarrhea, hypertension, and fatigue, which require careful management.

Regorafenib is an FDA-approved oral medication that targets multiple kinases involved in cancer growth and has shown survival benefits in patients with metastatic colorectal cancer after standard treatments have failed.

In addition to colorectal cancer, regorafenib significantly improves progression-free survival in patients with metastatic gastrointestinal stromal tumors (GIST) and is currently being tested in various other cancers, including renal cell carcinoma and hepatocellular carcinoma.
