What is the purpose of this trial?

This trial explores the possibility of safely reducing the intensity of chemoradiation (a combination of chemotherapy and radiation) for treating HPV-positive oropharyngeal cancer, which affects parts of the throat like the tonsils and the base of the tongue. Researchers aim to determine if this approach can maintain cancer control while potentially reducing side effects. Participants must have a specific type of throat cancer confirmed by tests, with evidence of the HPV virus in their blood and a low history of smoking. The main goal is to assess whether patients remain cancer-free for two years after treatment. As a Phase 2 trial, this research focuses on measuring the treatment's effectiveness in an initial, smaller group of people.

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?

Studies have shown that combining cisplatin with radiation therapy is generally well-tolerated by patients with HPV-positive oropharyngeal cancer. Research indicates that nonsmokers with this cancer type tend to have better survival rates, suggesting the treatment is effective and relatively safe for this group.

Although specific numbers on side effects aren't available, this treatment is widely used and considered safe enough for ongoing studies. For those considering joining a trial with cisplatin, these findings suggest a promising safety profile, particularly for individuals with HPV-related oropharyngeal cancer. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for oropharyngeal cancer?

Researchers are excited about this treatment for HPV-positive oropharyngeal carcinoma because it combines standard radiation therapy with cisplatinum in a potentially less intense way. Unlike traditional approaches that often involve high-intensity chemotherapy, this treatment aims to reduce the intensity while maintaining effectiveness. This approach could minimize side effects and improve the quality of life for patients by offering a gentler, yet still powerful, alternative to the current standard of care.

What evidence suggests that this trial's treatments could be effective for oropharyngeal cancer?

Studies have shown that cisplatin effectively treats HPV-positive oropharyngeal cancer (OPSCC). Research indicates that patients receiving cisplatin with radiotherapy, the approach used in this trial, have better survival rates than those receiving treatments like cetuximab. One study found that after two years, 97.5% of patients who received cisplatin were still alive, compared to 90% of those who received another treatment. This finding suggests that cisplatin improves survival chances for people with this type of cancer. Therefore, cisplatin combined with standard radiation is considered a strong option for treating HPV-positive OPSCC. ^{6 7 8 9 10}

Patients with HPV-positive oropharyngeal cancer who underwent risk- and response-adapted de-escalated radiation therapy (RT) and chemoradiation (CRT) showed significantly better functional outcomes, including improved swallowing function and higher body mass index (BMI), compared to those receiving standard high-dose treatment.

The study found that lower treatment intensity (RT50/CRT45) was associated with less PEG-tube dependency and reduced narcotic use, highlighting the benefits of de-escalation in treatment for this patient population.

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 52 patients with advanced nodal disease (N2 to N3) from upper aerodigestive tract carcinoma, targeted chemoradiation using the RADPLAT protocol resulted in a 59% clinical complete response rate in evaluable heminecks.

The combination of targeted chemoradiation and planned selective neck dissection achieved a high regional disease control rate of 91%, indicating that this approach is effective in managing advanced neck disease.

In a study involving 23 patients with HPV-positive oropharyngeal carcinoma, reduced dose chemoradiation (rdCRT) after induction chemotherapy showed similar progression-free survival (PFS) and overall survival (OS) rates compared to standard-dose chemoradiation (sdCRT), with 3-year PFS/OS rates of 83.3% for rdCRT and 87.5% for sdCRT.

The findings suggest that rdCRT could be a viable treatment option that reduces toxicity while maintaining effectiveness, supporting further Phase 3 clinical trials for radiation dose reduction in HPV-positive oropharyngeal carcinoma.

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.

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.

In a study of 35 patients with advanced squamous cell carcinoma of the head and neck, the combination of cis-platinum (CDDP) and radiotherapy (RT) resulted in a high complete response rate of 75%, with an overall response rate of 100%.

The treatment was well tolerated, with gastrointestinal and hematologic toxicities being the most common side effects, making CDDP plus RT a safe and effective option, especially for patients with good performance status and unresectable stage II or III disease.

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 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.

In a study of 104 patients with locally advanced head and neck squamous cell carcinoma, there was no significant difference in overall survival or recurrence-free survival between those treated with high-dose cisplatin and those treated with weekly cisplatin after surgery and chemoradiation.

The results suggest that weekly cisplatin may be a preferable option for patients with HPV-positive oropharynx cancer, as it could help maintain survival rates while potentially reducing treatment-related toxicity.
