Surgery Followed by Risk-Directed Post-Operative Adjuvant Therapy for HPV-Related Oropharynx Squamous Cell Carcinoma: "The Minimalist Trial (MINT)"

Phase 2

Active, not recruiting

• Conditions: HPV Related Oropharyngeal Squamous Cell Carcinoma
• Interventions: Drug: Cisplatin; Radiation: Intensity modulated radiation therapy; Radiation: Intensity modulated proton therapy; Procedure: Surgery; Other: FACT-H&N; Other: MD Anderson Dysphagia Inventory; Other: University of Michigan Xerostomia Index; Other: Scale of Subjective Total Taste Acuity; Other: Neck Dissection Impairment Index

• Registration Number: NCT03621696
• Lead Sponsor: Washington University School of Medicine

Brief Summary

The overarching goal of the MINT trial is to reduce treatment-related toxicity while maintaining efficacy. Patients with HPV-related oropharyngeal squamous cell carcinoma (OPSCC) will undergo resection of the primary tumor site and involved/at risk regional neck nodes.

Exclusion Criteria

• Prior curative therapy for HNSCC.
• Patient must not have known distant metastatic disease at presentation.
• History of prior invasive malignancy diagnosed within 2 years prior to study enrollment; exceptions are malignancies with a low risk of metastasis or death (e.g., expected 5-year overall survival (OS) > 90%) that were treated with an expected curative outcome, such as squamous cell carcinoma of the skin, in-situ carcinoma of the cervix uteri, non-melanomatous skin cancer, carcinoma in situ of the breast, or incidental histological finding of prostate cancer (TNM stage of T1a or T1b).
• Receiving any other investigational agents.
• Uncontrolled serious inter-current illness or serious psychiatric illness/social situations that would limit compliance with study requirements.
• Pregnant and/or breastfeeding. A negative serum or urine pregnancy test is required at screening for all female patients of childbearing potential.
