This study explores the safety of d-limonene, a commercially-available dietary supplement (food) as a potential therapeutic for the severe dry mouth (xerostomia) experienced by patients with head and neck cancer as a side effect of their anti-cancer treatment.
Primary Objective:To determine the maximum tolerated dose (MTD) of d limonene when combined with radiation and platinum based chemotherapy in subjects with loco regionally advanced head and neck squamous cell carcinoma (HNSCC) based upon dose limiting toxicity (DLT) Secondary Objective: * To evaluate the feasibility and subject compliance with adjuvant administration of d limonene daily up to a maximum of 4 months after completion of chemoradiation * To correlate the level of d-limonene measured in the plasma to the dose levels(s) administered to the subject * To correlate the level of d lim…
Inclusion Criteria: * Histologically or cytologically confirmed diagnosis of advanced loco regional squamous cell carcinoma of the nasopharynx (AJCC v8 Stage II IV); oropharynx (AJCC v8 Stage I III for HPV+ cancer, excluding T1 2N0; AJCC v8 Stage III IV for Human papillomavirus (HPV) negative cancer); larynx (AJCC v8 Stage III to IV); or hypopharynx (AJCC v8 Stage III to IV), scheduled to undergo chemoradiation. Patients with squamous cell carcinoma of the head and neck from an unknown primary site with involved nodes (N1 to 3) also qualify. * Scheduled to received definitive RT with concurre…
Administered orally at 2 to 8 grams daily
Standard of Care -All patients will receive standard radiation treatment of 66 to 70 Gy given in 33 to 35 fractions (2 to 2.12 Gy/fractions) over 6.5 to 7 weeks.
Standard of Care -Cisplatin as 100 mg/m2 IV
Xerostomia questionnaire consists of 4 items on dryness while eating/speaking and 4 on dryness at rest. Patients rate each symptom on an 11 point ordinal Likert scale from 0 to 10, with higher scores indicating greater xerostomia
