Biomarker-Guided Therapy for Oropharyngeal Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores whether a blood test can tailor treatments for individuals with HPV-positive oropharyngeal cancer, a type of throat cancer caused by the human papillomavirus. The goal is to determine if this test can guide treatment intensity, balancing effectiveness with fewer side effects. The trial includes various treatment paths, such as combinations of surgery, chemotherapy, and radiation, based on biomarker results. Individuals diagnosed with HPV-positive throat cancer and planning standard cancer treatments might be suitable for this study. As a Phase 2 trial, the research focuses on measuring treatment effectiveness in an initial, smaller group, offering participants a chance to contribute to advancements in personalized cancer care.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications. However, if you are taking medications that might interfere with the treatment, the investigators may ask you to stop them.
What prior data suggests that the NavDx testing device is safe for use in patients with oropharyngeal cancer?
A previous study found that DART therapy with docetaxel was well-tolerated in patients with throat cancer. The survival rate was high, and patients experienced fewer side effects compared to traditional treatments, suggesting it is relatively safe for human use.
For advanced radiation therapy (IMRT/IMPT) with or without cisplatin, studies have shown fewer long-term side effects than expected. The treatments effectively controlled the cancer, indicating a good safety profile for patients.
These findings demonstrate that both treatment approaches are generally safe and manageable, though individual experiences can vary.12345Why are researchers excited about this trial's treatments?
Researchers are excited about the use of blood-based biomarkers for guiding therapy in oropharyngeal cancer because it offers a personalized approach to treatment. Unlike standard treatments like surgery, radiation, and chemotherapy alone, this method can help tailor the intensity and type of treatment based on individual biomarker responses. This approach potentially minimizes unnecessary exposure to harsh treatments, reducing side effects and improving patient outcomes. By closely monitoring biomarkers, doctors can adapt treatment plans more dynamically, aiming for more effective cancer control.
What evidence suggests that this trial's treatments could be effective for oropharyngeal cancer?
Research has shown that blood tests, such as the NavDx device, can help customize treatment for HPV-positive throat cancer. In this trial, participants in Group 2 will receive a gentler form of radiation therapy (DART) combined with the drug docetaxel. Studies found that 96.2% of patients had their tumors well-controlled in the treated area, and 91.1% did not experience cancer progression. Participants in Groups 3 and 4 will receive advanced radiation therapies, such as IMRT and IMPT, with or without the drug cisplatin. These treatments have effectively controlled cancer, maintained high survival rates, and may reduce side effects. The goal is to lower the chance of cancer recurrence while effectively managing side effects.45678

Are You a Good Fit for This Trial?
Adults with HPV-positive oropharyngeal squamous cell cancers eligible for surgery or chemoradiotherapy can join. They must not have distant metastases, be HIV+ or immunocompromised, and women of childbearing potential need a recent negative pregnancy test. Participants should be able to complete questionnaires and provide blood samples.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- Blood-Based Biomarkers
Trial Overview
The trial is testing if blood-based biomarkers can guide treatment intensity for better outcomes in head and neck cancer patients. It involves standard treatments like radiation (using high energy rays) and chemotherapy (with drugs like cisplatin), along with new tests using the NavDx device to detect cancer recurrence early.
How Is the Trial Designed?
Patients undergo IMRT or IMPT therapy QD on days 1-40 Monday-Friday for 28 or 35 fractions based on biomarker response along with concurrent cisplatin IV over 1-2 hours QW on Monday, Tuesday, or Wednesday or once every 3 weeks for 6 doses (or accepted alternate regimen when drug shortage applies per physician discretion). Treatment continues in the absence of disease progression or unacceptable toxicity. Patients undergo MBSS prior to RT and at 3 and 12 months post RT. Patients undergo CT, PET/CT, or MRI at baseline and 3 months and 1, 2 and 5 years post treatment. Patients undergo blood specimen collection for NavDx testing pre-RT, 4 weeks into RT, anticipated fraction 20, end of RT, 3, 6, 9, 12, 15, 18, 21, 24, 30, 36, 48, and 60 months as well as saliva sample collection at pre-op, end of RT, and any clinical recurrence.
Patients undergo IMRT or IMPT QD on days 1-40 Monday-Friday for a total of 30 fractions within 6 weeks of standard of care surgery. Depending on risk status, patients may also receive concurrent cisplatin IV over 1-2 hours once a week QW on Monday, Tuesday, or Wednesday or once every 3 weeks for 6 doses (or accepted alternate regimen when drug shortage applies per physician discretion). Treatment continues in the absence of disease progression or unacceptable toxicity. Patients undergo MBSS at pre-op, 2 weeks post-op, and 3 and 12 months post-treatment. Patients also undergo CT, PET/CT, or MRI at baseline and 3 months and 1, 2 and 5 years post treatment. Patients undergo blood specimen collection for NavDx testing at pre-op, 1-2 days post-op, 2 weeks post-op, end of RT, and 3, 6, 9, 12, 15, 18, 21, 24, 30, 36, 48, and 60 months as well as saliva sample collection at pre-op, end of RT, and any clinical recurrence.
Patients undergo DART with/without mucosal sparing BID on days 1-12 Monday-Friday for a total of 20 fractions within 8 weeks of standard of care surgery. Patients receive concurrent docetaxel IV over 1 hour on days 1 and 8 (Mondays preferred). Treatment continues in the absence of disease progression or unacceptable toxicity. Patients undergo MBSS at pre-op, 2 weeks post-op, and 3 and 12 months post-treatment. Patients also undergo CT, PET/CT, or MRI at baseline and 3 months and 1, 2 and 5 years post treatment. Patients undergo blood specimen collection for NavDx testing at pre-op, 1-2 days post-op, 2 weeks post-op, end of RT, and 3, 6, 9, 12, 15, 18, 21, 24, 30, 36, 48, and 60 months as well as saliva sample collection at pre-op, end of RT, and any clinical recurrence.
Patients undergo observation following standard of care surgery. Patients undergo modified barium swallow study (MBSS) at pre-op, 2 weeks post-op, and 3 months follow-up. Patients also undergo CT, PET/CT, or magnetic MRI at baseline and 3 months and 1, 2 and 5 years post treatment. Patients undergo blood specimen collection for NavDx testing at pre-op, 1-2 days post-op, 2 weeks post-op, and 3, 6, 9, 12, 15, 18, 21, 24, 30, 36, 48, and 60 months as well as saliva sample collection at pre-op, end of RT, and any clinical recurrence.
