What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores a special imaging method to monitor head and neck cancer treatment. It focuses on using a new type of PET/CT scan with the [18F]-AraG radiotracer to track changes in cancer for patients undergoing standard chemoradiotherapy. The trial specifically targets those with advanced squamous cell carcinoma in the larynx or HPV-negative oropharynx who will receive a specific radiation and chemotherapy plan. Individuals diagnosed with this type of cancer and planning to follow the standard treatment may find this trial suitable. As an Early Phase 1 trial, the research aims to understand how this new imaging method works in people, offering a unique opportunity to contribute to advancements in cancer treatment monitoring.

Do I need to stop my current medications for the trial?

The trial does not specify if you need to stop your current medications. However, you cannot participate if you are on systemic steroid therapy or any immunosuppressive therapy within 7 days before the PET/CT scan.

What prior data suggests that the [18F]-AraG PET/CT scan is safe for monitoring head and neck cancer?

Research shows that [18F]-AraG, a type of imaging agent, is still under study to determine its safety for humans. Currently, there is limited information about its safety in humans. The trial is in an early stage, focusing on the treatment's safety and the body's reaction to it.

Specific information about side effects or problems from using [18F]-AraG in people is not yet available. However, early trials closely monitor participants for any issues. If [18F]-AraG had been approved for another use, it might suggest greater safety, but that is not the case here. By joining this trial, participants contribute to understanding the safety of this imaging agent for future patients. ^{1 2 3 4 5}

Why are researchers excited about this trial?

[18F]-AraG PET/CT scans are unique because they use a radiotracer to provide a precise image of head and neck cancer activity. Unlike traditional imaging methods, which often rely on anatomical changes, this technique targets the metabolic activity of the cancer cells. Researchers are excited because this approach could lead to earlier detection and more accurate monitoring of the disease, potentially improving treatment outcomes and personalizing patient care.

What evidence suggests that [18F]-AraG PET/CT scan is effective for monitoring Head and Neck Cancer?

Research has shown that [18F]-AraG is a promising tool for monitoring cancer treatment. This special imaging agent accumulates in active CD8+ T cells, which play a key role in fighting tumors. Studies have found that [18F]-AraG PET scans can reveal different patterns in tumors, indicating interactions between the cancer and immune system. This helps doctors evaluate how well the immune system responds to treatment. Although more research is needed, early findings suggest that [18F]-AraG could be useful in tracking how patients with head and neck cancer respond to therapy. Participants in this trial will undergo [18F]-AraG PET/CT scans to assess these interactions. ^{1 6 7 8 9}
