NCT06997094

Brief Summary

This phase I trial tests the safety, side effects, and best dose of decitabine in combination with standard of care surgery, radiation, and/or chemotherapy and the effectiveness of the combination in treating patients with head and neck squamous cell cancers that are not caused by human papilloma virus (HPV-negative) and that can be removed by surgery (resectable). Decitabine, an antimetabolite, stops cells from making deoxyribonucleic acid (DNA) and may kill tumor cells. Studies have shown that medications like decitabine can make some types of solid tumors more sensitive to chemotherapy. This allows the chemotherapy to be more effective, with slower progression and longer survival. Decitabine is also a clinically active demethylating agent, and may help make tumor cells more sensitive to radiation therapy. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill tumor cells and shrink tumors. External beam radiation therapy (EBRT) is a type of radiation that uses a machine to aim high-energy rays at the tumor from outside the body. Chemotherapy drugs work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving decitabine in combination with standard of care surgery, radiation and/or chemotherapy may be safe, tolerable, and/or effective in treating patients with surgically resectable HPV-negative head and neck squamous cell cancers.

Outcome Measures

Primary Outcomes (2)

  • Maximum tolerated dose (MTD) of preoperative decitabine

    MTD will be selected based on the rate of grade 4 toxicity and correlative methylation response data.

    From first dose of preoperative decitabine to the first dose of adjuvant decitabine

  • MTD of adjuvant decitabine

    MTD will be selected based on the rate of grade 4 toxicity and correlative methylation response data.

    From first dose of adjuvant decitabine to 28 days after the end of treatment

Secondary Outcomes (5)

  • Incidence of acute (early onset) adverse events

    Up to 90 days

  • Incidence of late onset adverse events

    From 91 days to 2 years

  • Event-free survival

    1 year, 2 years, 5 years

  • Overall survival

    1 year, 2 years, 5 years

  • Quality of Life - EORTC QLQ-H&N35

    Baseline, at end of treatment, every 4-6 months post end of treatment for up to 2 years

Study Arms (1)

Treatment (decitabine, surgery, radiation)

EXPERIMENTAL

PREOPERATIVE PHASE: Patients receive decitabine IV over 1 hour QD for 3 days and undergo standard of care surgery within 28 days of receiving decitabine. ADJUVANT TREATMENT: Patients receive decitabine IV over 1 hour QD for 3 days every 3 weeks during radiation therapy in the absence of disease progression or unacceptable toxicity. Patients also undergo EBRT QD on 5 days per week for up to 5-35 treatments per standard of care. Patients may receive concurrent chemotherapy of choice per standard of care. Patients also undergo blood sample collection throughout the study.

Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:
