• Registration Number: NCT04490460
• Lead Sponsor: Eden Miller

Brief Summary

Evaluation of the safety and effects on glycemic control of medical food formulation WBF-0031 in subjects with abnormal glucose control.

Detailed Description

The current study aims to investigate if altering the microbiome though Pendulum Glucose Control supplementation can have implications aimed at maintaining normal blood glucose levels that are critical for preventing diabetes and its metabolic complications. The experimental design consists of two-12 week treatment periods in subjects with prediabetes, as defined by the National Diabetes Prevention Program (DPP) criteria.

The first study period of 12 weeks will be double-blinded, placebo-controlled. The Pendulum Glucose control and placebo will be in a capsule form and identical in appearance, and dispensed to each participant according to the randomization schedule in the first 12 weeks. All subjects will receive the active product (Pendulum Glucose Control) in the second, subsequent 12 week period.

Fasting total cholesterol, triglycerides, LDL, and HDL cholesterol, Fasting insulin and Glucose, High sensitivity C Reactive Protein (hsCRP), Chemistry 14, and HbA1c will be obtained at baseline, and during first and second study period, as well as vital signs of weight, BP, and waist circumference.

In addition, CGM (Abbott System Freestyle Libre Pro) data collection will be done three times during the study as noted in Schedule of Events. Baseline Blinded CGM will be performed for approximately 14 days prior to starting the intervention with Pendulum Glucose Control. Second Blinded CGM period for approximately 14 days will occur mid-way through the intervention (weeks 5 and 6) and a third period of Blinded CGM wear will occur during the last 2 weeks of the intervention (weeks 11 and 12). During the Baseline, study period one and period 2 a mixed meal tolerance consisting of 2 Boost Shakes will be given on day 5 of each sensor wear.

At the completion of the study, analysis of the vital signs, laboratory values, CGM data for average glucose, standard deviation, TIR (time in range), as well as glycemic results of MMT for each time interval; baseline, study period one, and two.

Arm && Interventions

Group	Intervention	Description
First 12 Weeks	WBF-0031	1 capsule administered twice daily with morning and evening meal for 12 weeks. Double blind 50% Placebo capsules identical to those containing WB-0031 and 50% WB-0031
Second 12 Weeks	WBF-0031	1 capsule administered twice daily with morning and evening meal for 12 weeks. All participants receiving WB-0031.

Primary Outcome Measures

Name	Time	Method
Safety Assessment of Adverse Events	30 weeks	Safety assessed via spontaneous adverse events reported during the study period and changes in chemistry 14 panel
Time spent in target blood glucose	Three 14 day intervals	Difference in daily glucose levels as measured by the amount of time spent in target blood glucose for each CGM wear period. Adjustable glucose thresholds will be set as follows:\<60 mg/dL, \<70 mg/dL, \>140 mg/dL, \>180 mg/dL and \>240 mg/dL. The percent of values above, below, and between these points will be calculated.

Secondary Outcome Measures

Name	Time	Method
Total Glucose Area Under the Curve (AUC) from baseline	24 weeks	Twelve and 24 week difference from baseline in total Glucose AUC during a standard Meal Tolerance Test (MMT)
Glucose peaks	30 weeks	Mean and standard deviation of post-prandial peak glucose and time to peak for each meal
A1c	Week 0, Week 12, Week 24	Improvement in A1c measured as a change in A1c levels from baseline at 12 and 24 weeks. Subjects enrolled in the study will have fasting A1c measurements at the time of enrollment and weeks, 0, 12 and 24 weeks.
Incremental Glucose Area Under the Curve (AUC) from baseline	24 weeks	Twelve and 24 week difference from baseline in incremental Glucose AUC during a standard Meal Tolerance Test (MMT)
