Conditions: Head and Neck Cancer Squamous Cell Carcinoma

Summary: this will be a multi-center, randomized, open-label, parallel-group study in adult patients with head and neck cancer.


Eligibility criteria:
inclusion criteria: 1. males or females aged more than 18 years at the time of icf signing 2. diagnosed based on position emission tomography (pet), computed tomography (ct), or magnetic resonance

committee on cancer \[ajcc\] guidelines 8th edition: * oral cavity, hypopharynx, or larynx (independent of p16): stage iii, iva, ivb per tnm guidelines; or * oropharyngeal p16 negative disease: stage iii, iva, ivb per tnm guidelines; or * oropharyngeal p16 positive disease: t4 (n0-n3), m0; or n3 (t1-t4), m0. 4. have measurable disease based on recist 1.1 5. subjects with head and neck cancer who have limited to those receiving definitive crt without surgical excision 6. subjects prescribed standard intensity-modulated radiation therapy (imrt) with daily fractions of 2.0 gy to a cumulative planned dose of 70 gy 7. subjects with eastern cooperative oncology group (ecog) performance statue (ps) of 0 \~ 2 8. subjects with the status of national cancer institute-common terminology criteria for adverse events (nci ctcae) version 5.0 grade 1 or lower for acute or chronic adverse reaction at the time of screening 9. subjects with an expected survival period of at least 20 weeks 10. subjects who can comply with the requirements of the clinical trial protocol 11. ability to understand and willingness to sign a written informed consent document exclusion criteria: 1. medical history 1. patients with a history of prior radiation to the head and neck region or with a known susceptibility to radiation (e.g., genetic condition, connective tissue disease) 2. patients with suicidal behavior, major depression, or other psychiatric disorders (bipolar disorder, attention deficit hyperactivity disorder, etc.) 3. patients with neuroleptic malignant syndrome, tardive dyskinesia, elderly with dementia, uncontrolled hyperglycemia and diabetes, and patients with venous thromboembolism 4. patients with orthostatic hypotension caused by cardiovascular disease (history of myocardial infarction or ischemic heart disease, heart failure or electrocardiogram abnormality), cerebrovascular disease, or conditions prone to hypotension (dehydration, decreased blood volume, and taking antihypertensive medication) 5. patients with a history of seizures 6. patients with possible cognitive and motor performance impairments (drowsiness and sedation) (however, if the investigator determines that cognitive and motor performance impairments are not likely to be impaired, enrollment is possible.) 7. patients with conditions that may increase core body temperature (such as strenuous exercise, exposure to excessive heat, taking anticholinergic drugs, or patients prone to dehydration) 8. patients with dysphagia \[those who are taking drugs that may be affected (however, if the investigator determines that dysphagia is unlikely to occur, enrollment is possible), those with aspiration pneumonia, those with esophageal dyskinesia\] 9. patients with a history of clinically significant allergic disease (with the exception of mild allergic rhinitis that does not require treatment) or hypersensitivity to other drugs(aspirin, antibiotics, etc.) 2. subjects who show abnormalities in the following test results at the time of screening: 1. alanine aminotransferase (alt) or aspartate aminotransferase (ast) \>2.5 × upper limit of normal (uln) 2. creatine clearance ≤60 ml/min (using cockcroft-gault (c-g) formula) 3. absolute neutrophil count (anc) \<1,500/µl 4. platelets \<100,000/µl 5. hemoglobin \<9 g/dl 6. serum calcium \>1.5 × uln 7. total bilirubin \> 2 × uln 8. prothrombin time (pt) (international normalized ratio \[inr\]) \>1.5 × uln or activated partial thromboplastin time (aptt) (sec) greater than the normal range 9. positive result for serum tests (hepatitis b or c virus, human immunodeficiency virus \[hiv\], rapid plasma reagin \[rpr\] test) 10. patients who show significant abnormalities in electrocardiogram (ecg) test results (e.g.,qtcf \> 450 msec) 3. subjects who received hypofractionated chemoradiation regimens (\> 2 gy per day) 4. subjects with known hypersensitivity to components or excipients of clinical investigational drugs 5. subjects with a history of drug abuse (especially hypnotics, centrally acting analgesics, opiates, or central nervous system drugs such as antipsychotic drugs) 6. contraindicated drugs and treatments: 1. subjects who have administered cytochrome p450 (cyp) 3a4 or cyp2d6 inducers or inhibitors (e.g., carbamazepine, rifampin, ketoconazole, quinidine, fluoxetine, paroxetine, itraconazole, clarithromycin, etc.) within 28 days of baseline 2. subjects who received chemotherapy within 28 days of baseline (drugs or treatment known to have anticancer effects such as cytotoxic chemotherapy, antihormonal therapy, and targeted therapy) 3. subjects who have administered intravenous antibiotics, antivirals, or antifungals within 14 days from baseline 4. subjects who have administered benzodiazepines (e.g., lorazepam) within 3 days from baseline 5. subjects who participated in another clinical trial within 4 weeks of the baseline and administered the clinical trial drug 7. subjects and their spouses (or partners) with childbearing potential who are not using medically acceptable methods of contraception for the duration of the trial and for 14 months (in female subjects) and 11 months (in male subjects) after the last dose of cisplatin treatment 8. subjects who, in the judgment of other investigators, are not suitable to participate in the study"
