What is the purpose of this trial?

This trial aims to determine if a personalized approach to radiation therapy matches the effectiveness of standard treatment for throat cancer caused by HPV, a common virus. Researchers seek to find out if a lower dose of radiation combined with standard chemotherapy results in fewer side effects and improved quality of life compared to the usual higher dose. Participants will complete questionnaires to assess their quality of life during the trial. Individuals with HPV-positive throat cancer, experiencing symptoms like difficulty swallowing or a persistent sore throat, may be suitable candidates for this trial. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants the opportunity to contribute to potentially groundbreaking treatment advancements.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that a personalized approach to radiation therapy for HPV-positive throat cancer can reduce side effects while maintaining effectiveness. Studies indicate that adjusting radiation doses based on a patient's genetic makeup helps avoid the severe side effects often seen with standard treatments.

Patients without low oxygen levels in their tissues receive a lower radiation dose of 30Gy over 15 days, compared to the usual 70Gy. Early results suggest this lower dose might be just as effective in treating cancer while causing fewer side effects.

For patients with low oxygen levels, the treatment resembles the standard approach, with doses up to 70Gy. This method aims to balance effective treatment with minimizing unwanted effects.

The trial is in phase 3, indicating that earlier studies have shown the treatment is likely safe. This phase will further test how well people tolerate it. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatment for throat cancer?

Researchers are excited about personalized radiation therapy for throat cancer because it tailors treatment based on the tumor's hypoxia status, which isn't typically done with standard treatments. Unlike the conventional approach that uses a one-size-fits-all radiation dose, this personalized method adjusts the radiation dose depending on whether the cancer is hypoxia-negative or hypoxia-positive. This could potentially reduce unnecessary radiation exposure and side effects for patients without hypoxia, while still effectively targeting more resilient tumors with a higher dose. By customizing the treatment, there's hope for improved outcomes and fewer side effects, making it a promising advancement in throat cancer care.

What evidence suggests that this trial's treatments could be effective for HPV-positive throat cancer?

Research has shown that personalized radiation therapy, which adjusts radiation doses for each patient, might be as effective as standard doses for treating HPV-positive throat cancer. In this trial, participants will join either a personalized chemoradiation therapy arm or a standard chemoradiation therapy arm. A study using genetic information suggested that adjusting radiation doses based on a person's genes can maintain high cure rates while potentially reducing side effects. Specifically, past patients with HPV-positive throat cancer experienced fewer side effects with personalized radiation therapy compared to traditional treatments. Personalized radiation therapy also aims to improve quality of life by reducing treatment intensity without losing effectiveness. These findings suggest that personalized radiation therapy could serve as a promising alternative to standard treatment. ^{1 2 3 4 6}

What Are the Treatments Tested in This Trial?

Interventions

• Personalized Radiation Therapy

Trial Overview The study compares personalized chemoradiation therapy (potentially lower radiation doses) against standard chemoradiation in treating HPV-positive throat cancer. It aims to determine if the personalized approach is as effective while causing fewer side effects and impacting quality of life differently.

How Is the Trial Designed?

Group I: Personalized Chemoradiation Therapy Experimental Treatment 3 Interventions

Patient without evidence of hypoxia will receive 30Gy in 2Gy per fraction. Concurrent chemotherapy will be given as per guidelines. After completion of chemotherapy and radiation therapy, a 4 month (+/- 4 weeks) posttreatment standard FDG PET/CT scan will be performed and if there is persistent disease, standard neck dissection will be performed. Further standard of care will be given pending pathologic findings.1. Hypoxia negative: The entire target volume which includes GTV and CTV will receive 30Gy in 2 Gy per fraction over 15 days (PTV30). 2. Hypoxia positive (same as the standard of care): The CTV will receive 50Gy in 2Gy per fraction over 25 days. This is name PTV50 and will receive 50Gy in 2Gy per fraction over 25 days. The GTV will receive an additional boost of 20Gy in 2 Gy per fraction so that the total PTV70 dose is 70Gy.

Group II: Standard Chemoradiation Therapy Active Control 3 Interventions

Patient will receive 70Gy in 2Gy per fraction regardless of hypoxia status. Concurrent chemotherapy will be given as per guidelines. After completion of chemotherapy and radiation therapy, a 4 month (+/- 4 weeks) posttreatment standard FDG PET/CT scan will be performed and if there is persistent disease, standard neck dissection will be performed. Further standard of care will be given pending pathologic findings.
