What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT06855524). This is a study registration, not published results. Lead sponsor: Mayo Clinic. Recruitment status: RECRUITING. Phase: PHASE2. Study type: INTERVENTIONAL. Enrollment: 34 participants (ESTIMATED). Conditions: Malignant Digestive System Neoplasm, Malignant Female Reproductive System Neoplasm, Breast Carcinoma, Lung Carcinoma, Malignant Solid Neoplasm. Interventions: PROCEDURE: Biospecimen Collection; DIETARY_SUPPLEMENT: Oligo-fucoidan; DRUG: Placebo Administration; OTHER: Questionnaire Administration. Primary outcome measures: Change in fatigue, weeks 1-8 , Baseline to 8 weeks. Brief summary: This phase II trial tests how well fucoidan works in preventing chemotherapy-related fatigue compared to a placebo in patients with gastrointestinal (GI), gynecological (GYN), breast, or lung cancer. Fatigue poses a burden in patients with malignancies undergoing systemic chemotherapy. Fucoidan is a dietary supplement made of complex sugar that contain sulfate groups attached to their sugar units (sulfated polysaccharide) which found in brown seaweed. It is thought to have anti-inflammatory, anti-viral, anti-thrombotic, anti-diabetic, and anti-tumor effects in pre-clinical models. Giving fucoidan may be effective in preventing chemotherapy-related fatigue in patients with GI, GYN, breast, or lung cancer.
