About this trial
This is an interventional prevention trial for Mucositis focused on measuring Mucositis, Uridine Phosphorylase Inhibitor, Head and Neck Cancer, Radiation
Eligibility Criteria
Inclusion Criteria: Participants must meet ALL of the following criteria at the time of screening unless otherwise specified: Patient must sign study specific informed consent prior to study entry. Male or Female patient aged 18 - 75 years. Pathologically (histologically or cytologically) proven (from primary lesion and/or lymph nodes) diagnosis of squamous cell carcinoma of the oral cavity (Refer Definition in 10.13.1), oropharynx or hypopharynx. Patients must have at least 1 mucosal site of the oral cavity/oropharynx/hypopharynx mucosa assessable by visual transoral inspection that will receive cumulative radiation dose of 70 Gy. Note: Unavoidable doses of at least 60 Gy, to include entrance, exit, and scatter doses, still constitutes planned radiation. Patients with tumors of the larynx or hypopharynx are eligible only if it is anticipated that at least 1 index site in the oral cavity/oropharynx/hypopharynx mucosa (Refer section 10.13.1) will receive cumulative radiation dose of 70 Gy. Selected Stage I to III or IVA-B per AJCC, Cancer Imaging Manual, 8th edition, at study entry, including no distant metastases other than non- metastatic SCCHN, based upon the following minimum diagnostic workup: History/physical examination, including documentation of tobacco/alcohol use and current medications (including opioids/dosing), within 8 weeks prior to randomization. Chest CT scan within 8 weeks prior to randomization. MRI or CT scan with contrast of tumor site within 8 weeks prior to randomization. Mucositis Grade ≤ 1 per WHO Scale and Xerostomia of Grade ≤ 2 per CTCAE version 5.0 ECOG Performance Status ≤ 2. Adequate bone marrow function as per CTCAE V 5, defined as follows (within 2 weeks prior to randomization): Absolute neutrophil count ≥ 1500cells/mm3 based upon CBC/differential obtained within 2 weeks prior to randomization. Platelets ≥ 100,000 cells/mm3 based upon CBC/differential obtained within 2 weeks prior to randomization. Hemoglobin ≥ 8.0 g/dl based upon CBC/differential obtained within 2 weeks prior to randomization (Note: The use of transfusion or other intervention to achieve Hgb> 8.0 g/dl is acceptable). Adequate hepatic function with bilirubin ≤ 1.5 x upper-normal limit (ULN), AST or ALT ≤3 x ULN within 2 weeks prior to randomization. Adequate renal function with serum creatinine < 1.5 mg/dl and creatinine clearance (CrC) ≥ 50 ml/min determined by 24-hour collection or estimated by Cockcroft-Gault formula. CrC male = [(140 - age) x (wt in kg)] / [(Serum Cr mg/dl) x (72)]. CrC female = 0.85 x (CrCl male) within 2 weeks prior to randomization. Normal serum calcium or normal corrected serum calcium within 2 weeks prior to randomization; formula for corrected calcium if albumin valued is below normal range: Corrected calcium (mg/dl) = (4 - [Patient's albumin (g/dl)] x 0.8) + Patient's measured calcium (mg/dl). Negative serum pregnancy test for women of childbearing potential. Women of childbearing potential and male participants with female partners of childbearing potential must practice adequate contraception. Exclusion Criteria: Patients who meet any of the following criteria at the time of screening will be excluded: Stage IVC (Any T, Any N, M1) per AJCC Cancer Staging Manual. 8th ed, or distant metastases at protocol study entry other than metastatic SCCHN. Prior invasive malignancy (except non-melanomatous skin cancer) unless disease free for a minimum of 3 years. Patients who have not fully recovered after prior surgery. (Patients who have had prior surgery and have fully recovered and patients who may have surgery in the future are eligible.). Severe, active co-morbidity, defined as follows: Symptomatic and/or uncontrolled cardiac disease, New York Heart Association Classification III or IV. Transmural myocardial infarction within the last 6 months. Acute bacterial or fungal infection requiring intravenous antibiotics at the time of screening. Chronic Obstructive Pulmonary Disease exacerbation or other respiratory illness requiring hospitalization or precluding study therapy at the time of screening. Hepatic insufficiency resulting in clinical jaundice and/or coagulation defects. Patients known to be sero-positive for human immunodeficiency virus (HIV), hepatitis B (HBV), hepatitis C (HCV). Collagen vascular disease, such as scleroderma. Previous treatment with palifermin or other keratinocyte growth factors, such as velafermin or repifermin, within 28 days of randomization. Any prohibited therapy 2 weeks prior to randomization (see Section 8.4). Pregnancy, breast feeding or women of childbearing potential and men who are sexually active and not willing/able to use medically acceptable forms of contraception. Substance abuse, medical, psychological or social conditions that may interfere with the patient's participation in the study or evaluation of the study results. Known hypersensitivity study medication or excipients in the formulation. Any illness or medical conditions that are unstable or could jeopardize the safety of the patient and his/her compliance in the study.
