A Randomized, Double-blind Study to Evaluate the Clinical Effect and Safety of Fucoidan in Patients With Squamous Cell Carcinomas of the Head and Neck

Phase 2

Recruiting

• Conditions: Squamous Cell Carcinomas of the Head and Neck
• Interventions: Other: Placebo( Potato starch); Dietary Supplement: Fucoidan

• Registration Number: NCT04597476
• Lead Sponsor: Hi-Q Marine Biotech International, Ltd.

Brief Summary

This phase II study is a randomized, double-blind study that seeks to evaluate the clinical effects and safety of fucoidan in the treatment of cancer patients with stage III/IV head and neck squamous cell carcinoma.

Patients will be centrally randomized in a 1:1 ratio to receive either Fucoidan or placebo (potato starch) Eligible subjects will receive fucoidan twice daily (BID) in combination with chemotherapy and radiation therapy over a 24-week treatment period.

Clinical effects and safety parameters for all subjects who complete the treatment period will be followed for an additional 72 weeks after the treatment period.

Detailed Description

This phase II study is a randomized, double-blind study that seeks to evaluate the clinical effects and safety of fucoidan in the treatment of cancer patients with stage III/IV head and neck squamous cell carcinoma.

Patients will be centrally randomized in a 1:1 ratio to receive either Fucoidan or placebo (potato starch) Eligible subjects will receive fucoidan twice daily (BID) in combination with chemotherapy and radiation therapy over a 24-week treatment period.

Clinical effects and safety parameters for all subjects who complete the treatment period will be followed for an additional 72 weeks after the treatment period.

The total length of the study for each subject will be approximately 100 weeks, comprising the following time periods: screening period (28 days), treatment period (24 weeks), and follow-up period (72 weeks).

7. Adequate bone marrow function, as defined by absolute neutrophil count ≥ 1,500/μL, platelet count ≥ 100,000/μL, and hemoglobin ≥ 9 g/dL.
8. Adequate hepatic function, with total bilirubin ≤ 1.5 × upper normal limit (UNL; patients with hyperbilirubinemia caused by Gilbert's syndrome may be eligible if total bilirubin ≤ 2.5 × UNL), aspartate aminotransferase (AST) ≤ 2.5 × UNL, alanine aminotransferase (ALT) ≤ 2.5 × UNL, and alkaline phosphatase (ALP) ≤ 2.5 × UNL.
9. Men and women of childbearing potential must consent to the use of effective contraception while on treatment period.
10. Patients must be able to understand and be willing to sign a written informed consent document.
11. Patients must be able to comply with the study protocol.

Exclusion Criteria

1. Diagnosed as nasopharyngeal cancer.
2. Body mass index (BMI) < 18.5.
3. Significant history of cardiac disease (i.e. uncontrolled hypertension, unstable angina, congestive heart failure, or uncontrolled arrhythmias, etc.).
4. Patients with a history of any other malignancy (except squamous or basal cell skin cancer or cervical carcinoma in situ) are ineligible, unless the patient has been continuously disease-free for at least 5 years.
5. Previously received chemotherapy, radiation therapy, or immunotherapy for head and neck cancer.
6. Dysphagia patients who do not consent to nasogastric (NG), orogastric (OG), or percutaneous endoscopic gastrostomy (PEG) feeding.
7. History or clinical evidence of any hyperthyroidism, cirrhosis, hepatic failure, human immunodeficiency virus (HIV) infection, renal failure (as determined by a serum creatinine > 250 µmol/L or > 2.83 mg/dL at screening), active tuberculosis (as confirmed by sputum or other microbiological methods within the last five years), or active hepatitis B/C.
8. Any other clinical disorders or unsuitable conditions that render the patient ineligible for this study, as determined by the principal investigator(s).
9. Treatment with any investigational product or health supplement within 28 days prior to enrollment.
10. Pregnant or breastfeeding women.
11. Non-compliance with the requirement for contraception or other aspects of the study protocol.
