Tokyo, June 24 -- UMIN Clinical Trials Registry (UMIN-CTR) received information related to the study (UMIN000061984) titled 'Study on the effect of continuous ingestion of a material for 1-deoxy-D-mannose on the host microbiome (gut and vaginal) and urinary excretion dynamics' on June 24.
Study Type:
Interventional
Study Design:
Basic Design - Single arm
Randomization - Non-randomized
Blinding - Open -no one is blinded
Control - Uncontrolled
Primary Sponsor:
Institute - Nakamura Gakuen University
Condition:
Condition - Healthy adults
Classification by malignancy - Others
Genomic information - NO
Objective:
Narrative objectives1 - To clarify the long-term effects and efficacy of 1-deoxy-D-mannose (DM) on the human body by conducting a continuous ingestion experiment of DM, and evaluating changes in the host microbiome (gut and verginal), and urinary DM excretion before and after ingestion.
Basic objectives2 - Bio-availability
Intervention:
Interventions/Control_1 - Duration: 29 days (1 day of pre-ingestion evaluation + 27 days of continuous ingestion + 1 day of post-ingestion evaluation)
Test materials: 1-deoxy-D-mannose
Dose: 1.0 g
Administration: Take once a day. On the 1st day (before continuous ingestion) and the 29th day (after continuous ingestion), the test material is ingested for evaluation, and 24-hour urine is collected. In addition, self-collection of feces and vaginal secretions is performed between 2 days before and the day of each evaluation test. During the 27 days in between, it is continuously ingested once a day.
