Clinical Trial Summary

A clinical study to evaluate the long-term safety of Sodium Oligomannate Capsules (GV-971)

Clinical Trial Description

Sodium oligomannate (Code: GV-971), a marine-derived oligosaccharide after extraction, separation and degradation from algae, can play a role in the treatment of Alzheimer's disease by reconditioning the dysbiosis of gut microbiota, preventing peripheral immune cells from invading the brain, inhibiting the inflammatory response in the brain, and targeting protein folding errors in the brain tissue. Phase I clinical study shows GV-971 was safe and tolerated in healthy adult volunteers when administered continuously at 1200 mg/dose or 1500 mg/day (750 mg/dose, bid) for 5 days. Phase II and III clinical studies show that the treatment of GV-971 at 900 mg/day dosage for 36 weeks can significantly improve the cognitive function of patients with mild to moderate Alzheimer's disease (AD) and was safe and well-tolerated. Sodium Oligomannate Capsules obtained approval from China's National Medical Products Administration (NMPA) on November 2, 2019, with approval letter number of 2019S00571. This product is a chemical drug with a registration classification of 1.2. It is approved for the clinical indication of mild to moderate Alzheimer's disease and the function of improving the cognitive function of patients. The clinical dosage and administration is 3 capsules (450 mg)/time, bid, po. Due to the limited number of subjects and observation period of medication in completed GV-971 clinical studies, and the screening of patients with the strict inclusion and exclusion criteria, the adverse reactions and long-term safety of GV-971 cannot be comprehensively observed and recorded. Therefore, according to the requirements of the NMPA for the marketing of new drugs, this study is intended to further carry out a post-marketing investigation on expanded population using a design of a 96-week intensive monitoring clinical trial to determine the incidence of known adverse reactions of GV-971 under long-term administration, observe the occurrence of new adverse reactions, analyze the correlation, incidence, severity, and risk factors of adverse reactions/events, and better guide the rational use of drugs in clinical practice. ;
