Risk Adapted De-Intensification of Radio-Chemotherapy for Oropharyngeal Squamous Cell Carcinoma

Is NCT05268614 recruiting? Yes, currently enrolling (May 2026). This Phase 2 trial studies Cisplatin for oropharyngeal squamous cell carcinoma.

Phase 2RecruitingUniversity of FloridaNCT05268614Data as of May 2026

Treatment: CisplatinThis study builds on the results of several prior studies that we have been involved with to test the hypothesis that Risk-Adapted De-Intensification of Radiation Therapy and chemotherapy based on HPV subtype, plasma circulating free HPV DNA (cfHPV DNA) level, and cfHPV DNA clearance rate produces Local-Regional Control rates that are similar to what has been achieved with more aggressive therapy in patients with Favorable Prognosis Oropharyngeal Squamous Cell Carcinoma (OPSCC).

Extracted eligibility criteria

Cancer type

Head and Neck Squamous Cell Carcinoma

Biomarker criteria

Required: HPV positivity

Tissue diagnosis of HPV and/or p16 positivity from the primary site or an associated lymph node.

Required: CDKN2A p16 positivity

Tissue diagnosis of HPV and/or p16 positivity from the primary site or an associated lymph node.

Performance status

ECOG 0–2(Ambulatory, capable of self-care)

Prior therapy

Cannot have received: radiotherapy

Exception: unless prior radiotherapy for oropharyngeal squamous cell carcinoma or to the head and neck is not deemed likely to compromise critical organs at risk in the opinion of the investigator

Prior radiotherapy for oropharyngeal squamous cell carcinoma (OPSCC) OR to the head and neck that, if combined with the protocol therapy, is deemed likely to compromise critical organs at risk in the opinion of the investigator.

Cannot have received: surgery with curative intent

Exception: tonsillectomy for diagnosis or excisional biopsy of a neck node for diagnosis are eligible if 'gross' cancer present at the primary site or in the neck at the start of radiation therapy

Prior surgery with curative intent for this OPSCC. Patients who have undergone tonsillectomy for diagnosis or excisional biopsy of a neck node for diagnosis are eligible provided there is 'gross' cancer present at the primary site or in the neck at the start of radiation therapy on this protocol with 'gross' defined as visible on an imaging study.

Lab requirements

Blood counts

Platelets ≥ 100,000 cells/mm3; Hemoglobin ≥ 8.0 g/dl (transfusion/intervention allowed to achieve threshold)

Kidney function

Serum creatinine < 2.0 mg/dl

Liver function

Total bilirubin < 2 x the institutional ULN; AST or ALT < 3 x the institutional ULN; physician attestation of no known history of liver disease can substitute for labs.

CBC/differential obtained within 12 weeks prior to treatment, with adequate bone marrow function defined as follows: Platelets ≥ 100,000 cells/mm3; Hemoglobin ≥ 8.0 g/dl (Note: The use of transfusion or other intervention to achieve Hgb ≥ 8.0 g/dl is acceptable.) Adequate renal and hepatic function within 12 weeks prior to treatment, defined as follows: Serum creatinine < 2.0 mg/dl; Total bilirubin < 2 x the institutional ULN; AST or ALT < 3 x the institutional ULN; Note that physician attestation of patient having no known history of liver disease can take the place of bilirubin and AST/ALT labs.
