Clinical Trial Summary

Purpose Phototherapy has an array of potential benefits in human health. The effects of a non-transdermal Fos Biomedical product (which utilizes the concept of phototherapy) on diabetes risk factors and sleep quality in people at risk for type 2 diabetes are unclear. Proposed is a single-blind randomized crossover placebo-controlled trial to assess the impact of daily use of the Fos Biomedical product for a 12-week period on cardio-metabolic risk factors and self-reported sleep quality among adults at risk for type 2 diabetes.

Specific Aims

• To determine the effects of the use of the Fos Biomedical product daily for 12 weeks, as compared to placebo patch, on glycemic control in adults at risk for type 2 diabetes. Specifically, to show that the use of the Fos Biomedical product for 12 weeks, as compared to placebo patch, will improve glycated hemoglobin in adults at risk for type 2 diabetes.

• To assess the effects of the use of the Fos Biomedical product, versus placebo patch, for a 12-week period on insulin sensitivity, serum lipids, C-reactive protein, anthropometric measures, self-reported sleep quality, and endothelial function in adults at risk for type 2 diabetes. Specifically, to show clinically meaningful improvement or neutral effects in insulin sensitivity, serum lipids, C-reactive protein, anthropometric measures, self-reported sleep quality, and endothelial function in adults at risk for type 2 diabetes.

• To assess the impact of Fos Biomedical product on liver function and kidney function in adults at risk for type 2 diabetes

Hypotheses

• Daily use of the Fos Biomedical product for 12 weeks will improve glycated hemoglobin in adults at risk for type 2 diabetes.

• Daily use of the Fos Biomedical product for 12 weeks will improve or have neutral effects on insulin sensitivity, serum lipids, C-reactive protein, anthropometric measures, self-reported sleep quality and endothelial function in adults at risk for type 2 diabetes.

• The use of the Fos Biomedical product will have no clinically meaningful adverse effects on liver function and kidney function in adults at risk for type 2 diabetes.

Description:

Background Pre-diabetes is a serious medical condition associated with elevated blood glucose that is higher than normal, but not high enough to be considered for a diagnosis of diabetes. An estimated 88 million adults aged 18 years and older have pre-diabetes in the United States (U.S.), yet more than 84% of those with pre-diabetes are unaware. Those with pre-diabetes are at increased risk for developing diabetes, cardiovascular disease (CVD), and stroke. Fifteen to 30% of individuals with pre-diabetes are likely to develop type 2 diabetes mellitus (T2DM) within 5 years. Pre-diabetes is a major risk factor associated with metabolic syndrome. Insulin resistance and excess body weight are common in both pre-diabetes and metabolic syndrome.

Metabolic syndrome - a cluster of risk factors that increase the risk of T2DM and CVD - affects about 35% of adults in the U.S. The risk factors for metabolic syndrome include hypertension, dyslipidemia, hyperglycemia, and excess body weight (especially due to excess central body fat). These risk factors represent an independent risk for developing T2DM, CVD, and stroke, as well as an increased risk of mortality. The risk of T2DM, CVD, and stroke increases with the number of metabolic risk factors. Persons with metabolic syndrome, when compared with healthy persons, have a 5-fold increased risk for T2DM. The combination of pre-diabetes and metabolic syndrome compared with healthy persons is associated with an even higher (i.e., 21-fold) risk for T2DM.

An inconsistent sleep schedule or a general lack of sleep has been associated with increased risk of developing T2DM. Specifically, sleep disturbance is associated with pre-diabetes and metabolic syndrome. Sleep disturbance is associated with poor cardio-metabolic control (i.e., hypertension, dyslipidemia, and a reduction in insulin level released after eating). Further, elevated stress hormones that keep the body awake have been associated with increased blood glucose level by increasing the production of glucose in the liver; decreasing glucose uptake in the muscles and fat cells; decreasing insulin secretion; and increasing insulin resistance. In addition, sleep deprivation has also been associated with increased appetite, which heightens the risk of T2DM. Again, insufficient sleep has been associated with higher levels of ghrelin, which increase appetite, and lower levels of leptin, which signals fullness. Therefore, improving sleep patterns has the potential to improve cardio-metabolic risk factors among those at risk for T2DM.

Lifestyle practices that promote good sleep hygiene and reduce stress have been associated with lower risk of T2DM and the control of cardio-metabolic risk factors among those at risk for T2DM. In addition, consistent sleep patterns have also been associated with improved glycemic control in T2DM. Phototherapy is thought to help improve sleep patterns in persons with circadian rhythm sleep disorders to normal sleeping patterns and times. Further, in a meta-analysis phototherapy therapy was shown to improve symptoms of vascular complications and quality of life that are linked to diabetes. In animal models, phototherapy has been shown to reduce abdominal fat. In addition, phototherapy has also been associated with improved insulin sensitivity in T2DM.

Phototherapy, also known as photobiomodulation (PBM), or low-level light therapy, has been known for almost 50 years but still has not gained widespread acceptance, largely due to uncertainty about the mechanisms of action. In recent years, much knowledge has been gained in this area. The primary site of light absorption in mammalian cells has been identified as the mitochondria, and more specifically, cytochrome c oxidase (CCO), an enzyme that contains both heme and copper centers and is known to reduce oxygen to water at the end of the mitochondrial respiratory chain. CCO has recently been shown to have an additional enzymatic activity: the reduction of nitrite to nitric oxide (NO) upon exposure to low-intensity light. The absorption peaks of CCO are in the visible (420-450 nm and 600-700 nm) and the near-infrared (760-980 nm) spectral region.

The leading hypothesis is that photons dissociate inhibitory NO from CCO, leading to an increase in electron transport, mitochondrial membrane potential and ATP production. Another hypothesis concerns light-sensitive ion channels that can be activated, allowing calcium to enter the cell. After the initial photon absorption events, numerous signaling pathways are activated via reactive oxygen species (ROS), cyclic AMP, NO and Ca2+, leading to activation of transcription factors. These transcription factors can lead to increased expression of genes related to protein synthesis, cell migration and proliferation, anti-inflammatory signaling, anti-apoptotic proteins, and antioxidant enzymes.

In a recent study showing that PBM reduced blood glucose and insulin resistance and reversed metabolic abnormalities in skeletal muscle in two diabetic mouse models, PBMT accelerated adenosine triphosphate (ATP) and ROS generation by elevating CCO activity. ROS-induced activation of phosphatase and tensin homolog (PTEN)/ protein kinase B (AKT) signaling after PBMT promoted glucose transporter GLUT4 translocation and glycogen synthase activation, accelerating glucose uptake and glycogen synthesis in skeletal muscle.

The effects of the non-transdermal Fos Biomedical patch system (which utilizes the concept of phototherapy) on cardio-metabolic risk factors and sleep quality in persons at risk for T2DM are unclear. Proposed is a randomized crossover placebo-controlled trial to assess the impact of the Fos Biomedical patch system use on cardio-metabolic risk factors and sleep quality among adults at risk for type 2 diabetes. Specifically, the investigators hypothesize that the use of the Fos Biomedical patch system for 12 weeks, as compared to placebo patch system, will improve glycated hemoglobin, other markers of cardio-metabolic risk factors and sleep quality in adults at risk for T2DM.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Glycated hemoglobin	Glycated hemoglobin (HbA1c) will be measured to assess the average concentration. HbA1c predicts the average amount of plasma glucose. The study team will use HbA1c to gauge the average amount of blood glucose level over a previous 3-month period.	Baseline, 12 weeks, 20 weeks, 32 weeks
Secondary	Insulin sensitivity	Glucose and insulin will be measured at each time point. Participants will be asked to fast at least 8 hours before glucose and insulin measurement. Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) will be calculated based on the fasting glucose and insulin levels to gauge the impact of phototherapy on glycemic control in the study participants. HOMA-IR will be calculated according to the formula: fasting insulin (µU/mL) multiplied by fasting glucose (mg/dL) divided by 405.	Baseline, 12 weeks, 20 weeks, 32 weeks
Secondary	Percent body fat	Percent body fat will be measured on the Tanita SC-240 Body Composition Analyzer using bioelectrical impedance analysis, which uses the resistance of electrical flow through the body to estimate body fat.	Baseline, 12 weeks, 20 weeks, 32 weeks
Secondary	Visceral fat rating	Visceral fat rating will be measured on the Tanita SC-240 Body Composition Analyzer.	Baseline, 12 weeks, 20 weeks, 32 weeks
Secondary	Total body water percent	Total water body water percent will be measured on the Tanita SC-240 Body Composition Analyzer.	Baseline, 12 weeks, 20 weeks, 32 weeks
Secondary	Body weight	Body weight will be measured for all study participants during each visit. It will be measured to the nearest 0.5 pound using a balance-type medical scale. Subjects will be measured in the morning (fasting), unclothed with the exception of undergarments.	Baseline, 12 weeks, 20 weeks, 32 weeks
Secondary	Body mass index (BMI)	Body mass index (BMI) will be measured as a participant's weight in kilograms divided by the participant's height in meters squared.	Baseline, 12 weeks, 20 weeks, 32 weeks
Secondary	Waist circumference	Waist circumference will be measured using the U.S. government standard protocol. It will be measured around the narrowest point between ribs and hips when viewed from the front after exhaling.	Baseline, 12 weeks, 20 weeks, 32 weeks
Secondary	Office blood pressure (BP)	Systolic and diastolic BP will be measured at each visit using an approved automated device. Blood pressure will be measured (average of two measurements, with five minutes between measurements) with the participant sitting in a quiet room.	Baseline, 12 weeks, 20 weeks, 32 weeks
Secondary	C-reactive protein (CRP)	Serum CRP values will be determined using a high sensitivity CRP (hsCRP) ELISA method.	Baseline, 12 weeks, 20 weeks, 32 weeks
Secondary	Serum lipids	Total cholesterol (Tchol), triglycerides (TG), and high-density lipoprotein (HDL) will be obtained by direct measurements. Very-low-density lipoprotein (VLDL) and low-density-lipoprotein (LDL) will be obtained by calculation: VLDL = TG/5; and LDL = Tchol - (VLDL + HDL). HDL:Tchol ratio will be used to evaluate the impact of treatment assignments on the lipid panel	Baseline, 12 weeks, 20 weeks, 32 weeks
Secondary	Endothelial function (EF)	The brachial artery reactivity studies (BARS) methodology to be employed is as described in the published "Guidelines for Ultrasound Assessment of Endothelial-dependent Flow-mediated Vasodilation of the Brachial Artery." The measure of interest is flow-mediated dilatation (FMD) of the brachial artery.	Baseline, 12 weeks, 20 weeks, 32 weeks
Secondary	Dietary pattern	To assess differences in diet quality and help the study team track any variation in dietary pattern over the course of the study, participants will be asked at baseline, 6 weeks and 12 weeks to provide information on the foods and beverages that they consumed during a 3-day period (i.e., 2 weekdays and 1 weekend day). For each 3-day period, participants will complete 3 consecutive 24-hour recalls using a web-based Automated Self-Administered 24-Hour Recall (ASA24) (available from the National Cancer Institute at http://riskfactor.cancer.gov/tools/instruments/asa24/), which will guide them through the process of completing the recall data, and these data will be reviewed by the study dietitian.	Baseline, 12 weeks, 20 weeks, 32 weeks
Secondary	Physical activity	Physical activity will be determined by the Seven-Day Physical Activity Recall [PAR]. 41 The PAR is one of the most widely used physical activity assessments in exercise science and epidemiological research. The popularity of this measure stems largely from its versatility and relative ease of use for research applications. The PAR provides detail regarding the duration, intensity, and volume (energy expenditure) of physical activity and can therefore be used for a variety of applications. Because it utilizes a one-week time frame, the data from the PAR is often considered representative of typical activity patterns. While it requires considerable cognitive effort by the participants, the interviewer-administered version can be completed in a reasonable amount of time (~20 minutes).	Baseline, 12 weeks, 20 weeks, 32 weeks
Secondary	Pittsburgh Sleep Quality Index (PSQI)	The PSQI questionnaire will be used to assess the self-reported quality of participants' sleep before and after each intervention phase. The PSQI is a self-rated questionnaire to assess perceived sleep quality and disturbances over a 1-month time interval. This 19-item instrument uses a Likert scale (ranging from 0 to 3) to assess seven clinically derived domains of sleep: sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction. The sum of scores for these seven components yields one global score. Clinical and clinimetric properties of the PSQI were assessed over an 18-month period with "good" vs. "poor" sleepers. A global score > 5 yielded a diagnostic sensitivity of 89.6% and specificity of 86.5% (kappa = 0.75, p < 0.001) in distinguishing good vs. poor sleepers.	Baseline, 12 weeks, 20 weeks, 32 weeks
Secondary	Liver function	Liver function will be assessed based on serum levels of aspartate transaminase (AST) and alanine aminotransferase (ALT).	Baseline, 12 weeks, 20 weeks, 32 weeks
Secondary	Kidney function	Kidney function will be assessed based on serum creatinine levels.	Baseline, 12 weeks, 20 weeks, 32 weeks
Secondary	Medication use	The study team will track any changes in medication use.	Baseline, 12 weeks, 20 weeks, 32 weeks
Secondary	Compliance	For each of the two treatment assignment periods, good compliance will be defined as >80% use of treatment during the respective 12-week treatment assignment. During the study assessment visit at the end of each treatment assignment, the study coordinator will meet with participants to assess compliance to the treatment assignment. Compliance will be assessed by self-report and by collecting the returned product use log at the end of each 12-week treatment assignment.	Baseline, 12 weeks, 20 weeks, 32 weeks
