What is the purpose of this trial?

This trial explores whether a lower-dose version of cisplatin-based chemoradiation (a combination of chemotherapy and radiation therapy) is as effective but with fewer side effects for people with HPV-related throat cancer. The trial targets patients who have undergone surgery to remove visible cancer cells and have high-risk features that might require more intense treatment. Individuals with certain risk factors, such as multiple affected lymph nodes or large tumors, may be suitable for this study. As a Phase 2 trial, the research focuses on measuring the treatment's effectiveness in an initial, smaller group, providing an opportunity to contribute to important findings.

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

The trial protocol does not specify if you need to stop taking your current medications. However, if you have severe co-morbidities or are taking medications that could interfere with the trial, you should discuss this with the trial team.

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 treatment is likely to be safe for humans?

Studies have shown that cisplatin-based chemoradiation can cause side effects such as nausea, vomiting, and weight loss. However, these side effects are similar to those of comparable treatments. Research indicates that most patients tolerate the treatment well, though some may experience more serious issues like kidney problems or hearing loss, particularly if they have pre-existing health conditions. This trial employs a milder version of the treatment, aiming to reduce these side effects while still effectively combating cancer. ^{1 2 3 4 5}

Why are researchers excited about this study treatment for oropharyngeal cancer?

Researchers are excited about the de-intensified cisplatin-based chemoradiation for oropharyngeal cancer because it aims to reduce the intensity of treatment while maintaining effectiveness. Unlike traditional approaches that often involve higher doses and longer durations, this treatment adjusts the dosage and administration duration based on the patient's risk level, potentially minimizing side effects. This personalized approach could lead to a better quality of life for patients without compromising treatment efficacy, making it a promising option in the fight against oropharyngeal cancer.

What evidence suggests that this de-intensified chemoradiation treatment could be effective for oropharyngeal cancer?

Research has shown that combining the drug cisplatin with radiation is crucial for treating oropharyngeal cancer, which affects the throat area. Studies have found this approach to be the most effective for advanced cases, as it helps shrink the tumor and prevent the cancer from spreading. For patients with oropharyngeal cancer linked to HPV, this treatment has produced excellent results, particularly when the cancer is detected early. Even older patients who can tolerate the treatment have experienced positive outcomes. This trial will investigate whether a lower dose of cisplatin-based chemoradiation can be equally effective, potentially resulting in fewer side effects. ^{6 7 8 9 10}

What Are the Treatments Tested in This Trial?

Interventions

• Cisplatin
• Cisplatin-based Radiation Therapy

Trial Overview

The study is testing a less intense version of chemoradiation therapy using cisplatin after robotic surgery for HPV-related throat cancer. It aims to see if lower doses are as effective but cause fewer side effects than standard treatment. High-risk patients will receive more intensive treatment.

This is a non-randomized study, with all patients undergoing de-intensified post-operative cisplatin-based chemoradiation. Dosage level and duration of administration will be determined by whether the patient is high risk or not as assessed by the treating investigator.

Published Research Related to This Trial

In a study of 18 patients with operable stage III and IV head and neck cancers, the combination of preoperative cis-platinum (cis-DDP) and radiation therapy resulted in a high response rate, with 89% of patients achieving a complete or partial response, and 72% showing complete responses in primary tumors.

The treatment was well-tolerated, with low site-related morbidity (15%) and a notable number of patients (5 out of 10) having pathologically negative tumors after surgery, indicating effective tumor reduction and safety of the regimen.

In a study of 153 patients with advanced oropharyngeal and nasopharyngeal carcinoma, adding weekly cisplatin to radiotherapy significantly improved overall survival, with a median survival of 27 months for radiotherapy alone compared to not reached for the chemoradiotherapy group.

While chemoradiotherapy showed higher complete response rates (80.5% vs. 67.1%) and better overall survival, it also resulted in increased toxicity, with 40% of patients experiencing severe side effects compared to 16% in the radiotherapy group.

In a phase I-II study involving 12 patients with unresectable head and neck squamous cell carcinomas, the combination of radiation and cisplatin (CDDP) resulted in a complete response in 66% of patients, with some remaining disease-free for up to 34 months after treatment.

The recommended dose of CDDP was determined to be 6 mg/m2/day, with manageable side effects; notably, mucositis severity was similar to that of radiation alone, and there was no significant nephro-, oto-, or neurotoxicity observed.

In a study of 72 patients with advanced head and neck cancer receiving concurrent chemoradiotherapy with generic cisplatin, treatment completion rates were high, indicating good tolerability of the drug.

The incidence of severe adverse events was relatively low, with only 14% experiencing grade 3/4 leukopenia and no severe kidney issues reported, suggesting that generic cisplatin is a safe option for this treatment.

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.

The addition of low-dose cisplatin (CDDP) to hyperfractionated radiation therapy (Hfx RT) significantly improved survival rates in patients with locally advanced squamous cell carcinoma of the head and neck, with 68% survival at 2 years compared to 49% with Hfx RT alone.

Despite the survival benefits, the combination treatment did not increase the incidence of severe radiation-induced toxicity compared to Hfx RT alone, although higher rates of hematologic toxicity were observed in patients receiving CDDP.

Patients with HPV-associated oropharyngeal squamous cell carcinoma (OPSCC) and nonsmokers showed better overall and disease-free survival, regardless of whether they received high dose (HD) or low dose (LD) cisplatin, indicating the importance of tumor characteristics in treatment outcomes.

A cumulative cisplatin dose of ≥200 mg/m2 was linked to a lower rate of distant metastasis, with the HD regimen allowing more patients to reach this dose while maintaining a similar toxicity profile to the LD regimen.

In a phase III trial involving 237 patients with inoperable head and neck cancer, intra-arterial (IA) cisplatin did not show improved tumor control compared to intravenous (IV) cisplatin, despite a higher dose being administered via IA.

Patients receiving IV cisplatin experienced worse late dysphagia, indicating a potential safety concern with IV administration, while overall survival and locoregional control were similar between both treatment methods.

In a study of 82 advanced head and neck cancer patients undergoing concurrent chemoradiotherapy with high-dose cisplatin, 26% experienced renal impairment, highlighting the need for careful monitoring of kidney function during treatment.

Risk factors for cisplatin-induced renal impairment included the use of calcium channel blockers and lower hemoglobin levels, while the use of proton pump inhibitors was associated with a reduced risk, suggesting potential strategies to enhance patient safety.
