Официальное название

A Study of the Efficacy Heterogeneity of Lactobacillus Paracasei LC19 Intervention in Patients With Newly Diagnosed Type 2 Diabetes

Обзор

This is a single-arm study to investigate the heterogeneity of glycemic response to Lactobacillus paracasei LC19 in patients with newly diagnosed type 2 diabetes. Participants will receive LC19 for 12 weeks, and changes in glycemic control will be evaluated.

Подробное описание

This is a single-center, open-label, single-arm study designed to investigate inter-individual variability in glycemic response to Lactobacillus paracasei LC19 (LC19) in patients with newly diagnosed type 2 diabetes (T2D). A total of 70 eligible participants with newly diagnosed T2DM will be enrolled. All participants will receive oral LC19 strain powder (2 packets per day, 2 g per packet) for 12 weeks. No placebo or active comparator will be included in this study.
