Decitabine in Combination With Standard of Care Therapy for the Treatment of Surgically Resectable HPV-Negative Head and Neck Cancer

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.

About this study

PRIMARY OBJECTIVE:

I. To prospectively evaluate the maximum tolerated dose (MTD) of decitabine, in both the preoperative and adjuvant phases of treatment, combined with standard-of-care therapy including surgery +/- chemoradiation for HPV-negative head and neck cancers.

SECONDARY OBJECTIVES:

I. Evaluation of acute (early onset) toxicities. (Stratified by methylation status) II. Evaluation of late onset toxicities. (Stratified by methylation status) III. Evaluation of event-free survival (EFS). (Stratified by methylation status) IV. Evaluation of overall survival (OS). (Stratified by methylation status) V. Evaluation of quality of life (QOL). (Stratified by methylation status)

CORRELATIVE RESEARCH OBJECTIVES:

I. In vivo methylation response to preoperative decitabine. II. Pharmacokinetics of decitabine. III. Exploratory circulating biomarkers.

OUTLINE: This is a dose-escalation study followed by a dose-expansion study.

PREOPERATIVE PHASE: Patients receive decitabine intravenously (IV) over 1 hour once daily (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.

After completion of study treatment, patients are followed up at 30 days, every 4-6 months for 2 years and then every 12 months for up to 5 years.

Primary outcomes

  1. Maximum tolerated dose (MTD) of preoperative decitabine

    Time frame: From first dose of preoperative decitabine to the first dose of adjuvant decitabine

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

  2. MTD of adjuvant decitabine

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

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

Secondary outcomes

  1. Incidence of acute (early onset) adverse events

    Time frame: Up to 90 days

    Defined as toxicities which begin during the start of adjuvant therapy until 90 days post end of treatment. Will be assessed using Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. The maximum grade for each type of acute AE will be recorded for each patient.

  2. Incidence of late onset adverse events

    Time frame: From 91 days to 2 years

    Defined as toxicities which begin from 91 days to two years post radiation therapy. Early onset toxicities can also be considered late toxicities if they persist for at least one day beyond the 90 days used to define late onset toxicities. Will be assessed using Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. The maximum grade for each type of acute AE will be recorded for each patient.

  3. Event-free survival

    Time frame: 1 year, 2 years, 5 years

    Defined as the interval from registration to last follow-up without an event, defined to include 1) recurrence of disease, 2) progression of disease, or 3) death.

  4. Overall survival

    Time frame: 1 year, 2 years, 5 years

    Defined as the interval from registration to last follow-up or death from any cause.

  5. Quality of Life - EORTC QLQ-H&N35

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

    Assessed using the EORTC (European Organization for Research and Treatment of Cancer) QLQ (Quality of Life) - Head & Neck 35 (H&N35) inventory, a 35-item questionnaire that assesses symptoms encountered specifically by patients with head and neck cancer. This measure generates 7 multiple-item scales (Pain, Swallowing, Senses, Speech, Social eating, Social contact, and Sexuality), in addition to 11 single items (e.g., opening mouth, sticky saliva, dry mouth). Scales range in score from 0 to 100. A high score for a functional scale represents a high/healthy level of functioning whereas a high score for a symptom scale or item represents a high level of symptomatology or problems.
