A Study to Determine the Safety and Tolerability of a Range of Doses of PeptiControl in Pre-diabetic Individuals

A Randomized, Double-blind, Placebo-controlled, Parallel Clinical Study to Determine the Safety and Tolerability of a Range of Doses of PeptiControl in Pre-diabetic Individuals.

A randomised, double blind, placebo controlled parallel study to examine the effects of a dose range of PeptiControl, a plant-based ingredient, in pre-diabetic males and females.

Study Overview

• Status: Completed
• Conditions: Overweight; Pre Diabetes
• Intervention / Treatment: Dietary supplement: PeptiControl™ (Low - Dose 435 mg/day); Dietary supplement: PeptiControl™ (Mid - Dose 870 mg/day); Dietary supplement: PeptiControl™ (High - Dose 2610 mg/day); Dietary supplement: Placebo Microcrystalline Cellulose

Detailed Description

The primary aim of this study is to evaluate safety and establish the effective dose to see acute effects in males and females with elevated fasting blood glucose. PeptiControl will be supplemented 30 minutes before lunch as a single oral dose of either 2610mg, 870mg or 435mg/day. A placebo group will also be included who will receive microcrystalline cellulose. Capsule number will be matched across all study arms to retain double blinding.

This trial incorporates continuous glucose monitoring (CGM) as wearable technology to measure blood glucose and time in range of the participants for the duration of the study. The trial will be conducted over 12 days, which includes a 2 day run-in period to gather baseline CGM data, followed by 6 days of PeptiControl supplementation and 4 days follow up on safety and blood glucose tracking post supplementation.

The primary endpoint will measure safety and tolerability via adverse event reporting and occurrence of hypoglycemic episodes evaluated by time below target range (70 - 180 mg/dL) during CGM throughout the intervention.

Secondary endpoints investigated during the trial will include safety of a dose range as assessed by a safety blood panel, glucose metabolism and insulin sensitivity, time in range, aspects of cognition and memory and hunger, satiety and fullness as assessed by VAS questionnaires.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
To investigate the safety and tolerability of a range of doses of PeptiControl™ as assessed by occurrence of hypoglycemic episodes evaluated by time below target range (70 - 180 mg/dL) during Continuous Glucose Monitoring (CGM)	The hypoglycemic events will be monitored and recorded from the day of IP initiation (Day 0) until the end of study (Day 10). The tolerability of different doses of PeptiControl™ will be assessed on the basis of the hypoglycemic episodes evaluated by time below target range (70 - 180 mg/dL) during CGM throughout the study in each arm.	Day 0 to Day 10

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
To explore the safety of a range of doses of PeptiControl™ as assessed by a safety blood panel comparing baseline and post dose parameters.	Blood samples will be taken from participants pre and post consumption of PeptiControl and analysed in a safety blood panel assessing liver, kidney and lipid markers for the identification of any changes from baseline.	Day 0 and Day 6
To assess the efficacy of range of doses of PeptiControl™ on blood glucose concentrations when given 30 minutes prior to Oral Glucose Tolerance Test (OGTT) compared to placebo	Thirty minutes post IP consumption, participants will consume a glucose solution (comprising of 75g glucose in approximately 250 ml water). Blood samples will then be collected at 15, 30, 60, 90, 120 and 180 mins for the assessment of blood glucose concentrations	Day 0
To assess the efficacy of range of doses of PeptiControl™ on Glucose metabolism as assessed by incremental Area Under Curve (iAUC)	The glucose iAUC will be derived from the OGTT. This assessment will be conducted at 0, 15, 30, 60, 90, 120 and 180 mins after glucose solution consumption	Day 0
To assess the efficacy of range of doses of PeptiControl™ on Pancreatic efficiency	Pancreatic efficiency will be evaluated by fasting serum insulin levels in blood Fasting insulin: Normal range - 2.6-24.9 μU/mL (17.8-173 pmol/L)	Day 0 and Day 6
To assess the efficacy of range of doses of PeptiControl™ Time in range via CGM (Continuous Glucose Monitoring).	Continuous glucose monitoring device automatically calculates the time in the blood glucose target range (70 - 180 mg/dl) as well as above and below the target range	Starting from day -2 and worn continuously until day 10 with readings taken at day -2, day 0, day 6, day 10
To assess the efficacy of range of doses of PeptiControl™ on Insulin sensitivity as assessed by Homeostatic Model Assessment for Insulin Resistance (HOMA-IR).	Insulin sensitivity will be assessed by HOMA-IR. The HOMA - IR score will be calculated using the formula: fasting insulin (mU/L) x fasting glucose (mmol/L)/22.5. Fasting insulin: Normal range - 2.6-24.9 μU/mL (17.8-173 pmol/L) Fasting Glucose: Normal range - 4.11-6.05 mmol/L(74-109 mg/dL)	Day 0 and Day 6
To assess the efficacy of range of doses of PeptiControl™ on Working memory as assessed by Paired Associate Learning test	Working memory will be assessed using the Validated Paired Associate Learning test by Creyos.	Day 0, Day 6, and Day 10
To assess the efficacy of range of doses of PeptiControl™ on Selective attention as assessed by Stroop test.	Selective attention will be assessed using the Double Trouble/Stroop test by Creyos	Day 0, Day 6, and Day 10
To assess the efficacy of range of doses of PeptiControl™ on Hunger, satiety and fullness as assessed by the Visual Analog Scale (VAS)	The VAS will be 100 mm in length with words anchored at each end expressing the most positive and the most negative rating. It will assess five components: hunger, satiety, fullness, prospective food consumption and desire to eat.	Day 0, Day 6, and Day 10
