What You Need to Know Before You Apply

What is the purpose of this trial?

This research is being conducted to understand if treatment can be tailored for participants with HPV-related oropharynx cancers using both clinical features (stage of the tumor, smoking status) combined with an investigational HPV blood test. The names of the test and treatments involved in this study are: * NavDx® HPV ctDNA testing (HPV blood test) * Radiation therapy * Chemotherapy: Cisplatin, or Carboplatin and Paclitaxel (not all participants receive any or all of these agents)

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 to get specific guidance based on your situation.

Is the treatment for HPV-related oropharyngeal cancer safe?

Cisplatin, often used with radiation therapy for HPV-related oropharyngeal cancer, is known to cause long-term side effects, which has led to exploring other treatments like carboplatin that might have fewer side effects. Radiation therapy alone is also considered, but it can still cause significant long-term toxicity. ^{1 2 3 4 5}

How is the treatment with Cisplatin, Paclitaxel, and Radiotherapy unique for HPV-related oropharyngeal cancer?

This treatment is unique because it combines Cisplatin and Paclitaxel with Radiotherapy, which is different from other approaches that might use Cetuximab instead of Cisplatin to reduce side effects. Cisplatin is often preferred for its effectiveness, especially in HPV-positive cases, despite its higher toxicity compared to alternatives like Cetuximab. ^{2 3 6 7 8}

What data supports the effectiveness of the treatment for HPV-related oropharyngeal cancer?

Research shows that cisplatin, when used with radiation therapy, is effective for treating HPV-positive oropharyngeal cancer, with better outcomes compared to cetuximab. This combination is considered the standard treatment for this type of cancer. ^{1 2 3 7 9}

How Is the Trial Designed?

Group I: LOW RISK RT (ALONE OR WITH SOC CHEMO Experimental Treatment 3 Interventions

The research study procedures include: screening for eligibility, and study treatments including evaluations and follow-up visits * NavDx HPV ctDNA Testing: Blood will be collected and shared with an outside lab for analysis (less than 10 mL of blood or about 2 teaspoons). The results of this test will determine what radiation dose received . The specimens will be de-identified. The specimens will be banked for future use. * Radiation Therapy: Lower risk participants will receive a lower dose and treatment will only last 5-6 weeks. * Chemotherapy: Chemotherapy and radiation therapy are both considered standard treatments for your type of cancer. The study doctor will decide whether or not chemotherapy with radiation and the type of chemotherapy. * Bolus Cisplatin: Infused every 21 days for up to 2 or 3 doses. * Weekly Cisplatin or Carboplatin with Paclitaxel: Infused weekly during radiation therapy

Group II: INTERMEDIATE RISK RT (ALONE OR WITH SOC CHEMO Experimental Treatment 3 Interventions

The research study procedures include: screening for eligibility, and study treatments including evaluations and follow-up visits * NavDx HPV ctDNA Testing: Blood will be collected and shared with an outside lab for analysis (less than 10 mL of blood or about 2 teaspoons). The results of this test will determine what dose of radiation received. The specimens will be de-identified. The specimens will be banked for future use. * Radiation Therapy: Higher risk participants will receive standard radiation dose for up to 7-8 weeks * Chemotherapy: Chemotherapy and radiation therapy are both considered standard treatments for your type of cancer. The study doctor will decide whether or not chemotherapy with radiation and the type of chemotherapy. * Bolus Cisplatin: Infused every 21 days for up to 2 or 3 doses. * Weekly Cisplatin or Carboplatin with Paclitaxel: Infused weekly during radiation therapy

In patients with stage III to IVb HPV-positive oropharyngeal cancer, active smokers had a significantly higher rate of distant metastases (22%) compared to never or former smokers (5%), indicating smoking status is a critical predictor of cancer progression.

Patients with T4 tumors also showed increased rates of distant metastases (15%) compared to those with T1 to T3 tumors (6%), and those treated with cetuximab-based bioradiotherapy had a higher rate of metastases (23%) compared to those receiving cisplatin-based chemoradiotherapy (5%), suggesting the need for intensified treatment strategies for these high-risk groups.

In a study of 1,149 patients with advanced head and neck squamous cell carcinoma, carboplatin-based chemoradiotherapy showed similar cancer-specific mortality rates compared to cisplatin-based therapy, indicating that carboplatin can be an effective alternative for patients unable to receive cisplatin.

Both carboplatin and cisplatin-based chemoradiotherapy were found to be more effective than radiation therapy alone or radiation with cetuximab, suggesting that carboplatin should be further investigated as a viable treatment option for certain patients.

In a phase 3 trial involving 334 patients with HPV-positive low-risk oropharyngeal cancer, cetuximab did not reduce severe toxicity compared to cisplatin, with both treatments showing similar rates of severe side effects at 24 months.

However, cetuximab was associated with significantly worse outcomes in terms of overall survival (89.4% vs 97.5%) and recurrence rates (16.1% vs 6.0%) compared to cisplatin, indicating that cisplatin remains the preferred treatment for these patients.

In a study of 160 patients with advanced oropharyngeal squamous cell carcinoma treated with carboplatin, paclitaxel, and radiation over 10 years, the overall survival rates were 81.7% at 3 years and 70.7% at 5 years, indicating effective treatment outcomes.

The treatment demonstrated an acceptable side effect profile, with the most common adverse effect being acute dysphagia (75.25%), and only 11.9% of patients experiencing significant hematologic toxicities, suggesting carboplatin may be a safer alternative to cisplatin.

Patients with locally advanced oropharyngeal squamous cell carcinoma who received cisplatin (CDDP) had a significantly better 2-year overall survival rate compared to those treated with cetuximab (CTX), with a hazard ratio of 1.68 indicating higher mortality for CTX users.

Cisplatin also resulted in lower overall treatment costs compared to CTX and carboplatin, despite higher rates of antiemetic use and hospital visits for side effects, suggesting it may be a more cost-effective option for treatment.

A phase 2 trial involving 39 patients with HPV-related oropharyngeal squamous cell carcinoma showed that intensity-modulated radiation therapy (IMRT) alone resulted in a 90% complete response rate, indicating high efficacy without chemotherapy.

The treatment demonstrated a 2-year progression-free survival rate of 94% and a 100% overall survival rate, with manageable toxicity, as only 26% experienced severe mucositis and no long-term severe adverse effects were reported.

In a study of 421 patients with HPV-associated oropharyngeal squamous cell carcinoma, high-dose cisplatin (HDC) showed better outcomes for stage III disease, including lower rates of locoregional recurrence and distant metastasis, as well as improved overall survival compared to triweekly carboplatin (TC).

However, HDC was associated with significantly higher toxicity, including increased rates of severe leukopenia and weight loss, suggesting that TC may be a safer option for patients with early-stage disease.

In a meta-analysis of 8 studies involving 1665 patients, treatment with cisplatin (CDDP) combined with radiotherapy resulted in significantly better overall survival (OS) and lower rates of locoregional recurrence (LRR) compared to cetuximab (C225) with radiotherapy for HPV-positive oropharyngeal cancer.

Patients receiving CDDP had a 2.2-fold lower risk of death and a 2.9-fold lower risk of locoregional recurrence, indicating that CDDP-based chemoradiotherapy should remain the standard treatment for p16-positive oropharyngeal cancer.

In a study of 31 patients with low-risk HPV-positive oropharyngeal squamous cell carcinoma, treatment with weekly cisplatin and radiotherapy resulted in excellent disease control, with no recurrences or deaths reported during a median follow-up of 30 months.

The treatment was generally well-tolerated, with 84% of patients completing at least 5 cycles of cisplatin, although 71% experienced grade 3 mucositis, indicating some side effects but no need for enteral feeding at 12 months.
