Taking part in this study is voluntary. Your participation in this study is voluntary. You do not have to be in this study if you do not want to, and you can leave the study at any time. This study is being conducted by Stephanie Kim, M.D. and her team. Please read all sections of the informed consent document.
As one of the Signos subscribed users, you are being asked to take part in this study. Users that are part of Signos fee-based subscription app via smartphone are asked to participate in this study for assessing effect of continuous glucose monitoring for general wellness and weight optimization. We ask that you read this document carefully and ask any questions you may have before agreeing to be in the study. After reading the consent form, if you would like to participate, you will be asked to sign this form. You will be given a signed copy of the consent form for your records.
What is the purpose of this study? The purpose of the study is to use continuous glucose data for general wellness for participating Signos users that utilizes diet, exercise, eating, and lifestyle habits. The Signos app will integrate the data to recommend customized solutions to alter lifestyles in order to optimize weight management. The Signos smartphone app (iOS/Android) uses an algorithm to incentivize subjects to adhere to weight loss efforts and to incorporate healthier habits. The Signos smartphone app will use CGM (continuous glucose monitoring) data for prolonged retention of healthier habits can.
How many people are we expecting to take part in this study? If you agree to participate, you will be one of the about 20,000 subjects who will be participating in this study. Your participation will last approximately for a total of up to 3 years. The Signos app will collect CGM data for up to 2 years and one year of additional follow-up after the cessation of period of use of CGM.
Will you benefit from taking part in this study? You may or may not personally benefit from being in this research study. Some of the potential benefits of study participation may include weight management (e.g. weight loss), development of healthy eating habits, including portion control, elimination of frequent snacking, and reduced portion sizes, identification of irregular blood glucose levels, etc. We hope that the CGM information integration will provide you with recommendations to help you manage your weight effectively.
Who can participate in the study? To take part in this study, you must be or have the following:
There are some exclusion criteria that may prevent you from being part of the study. You will not be able to participate in the study if you have any of the following:
What does this study involve? Once you are interested, information about study procedures and requirements will be provided for your review. Additionally, an oral glucose tolerance test (OGTT) will be performed. If you decide to participate, the study team will review inclusion and exclusion criteria and an informed consent process is completed in the Signos platform. A telemedicine physician will review the eligibility and prescribe CGM via a designated pharmacy. The pharmacy will ship the CGM with instructions to the participant. The study will assess how well CGM data works in customizing your weight management program using an integrated algorithm of the Signos mHealth smartphone app. The CGM will measure your glucose level in the fluid under the skin. It consists of a sensor that is inserted into the skin, a transmitter attached to the sensor, and a display device. Every 5 minutes, the transmitter sends glucose readings to the display device. The Signos app stores the readings in a “real-time” mode where the numbers from the transmitter are shown on the Signos app display continuously.
Your documentation will be reviewed by an independent physician. A prescription for CGM is written by the physician to a designated pharmacy. You will receive a study kit along with the CGM from the study sponsor with video instructions on how to use the CGM. The kit will include education and training on the CGM system that will provide your glucose data. The CGM system to be used in the study is made by Dexcom, Inc. The CGM kit has a transmitter and appropriate number of sensors corresponding to your subscription plan. The sensor has a plastic body and contains a thin, small needle and sensor wire the size of a human hair. Once inserted, the needle is removed, and the sensor wire remains. The transmitter snaps on top of the sensor, and an athletic patch is provided that can be optionally applied to further affix the sensor in place. The sensor wire measures the glucose level in the fluid beneath the skin every 5 minutes.
This information is sent by the transmitter to the display device. The sensor works for up to 10 days and then needs to be replaced. The first insertion will be known by the study team at insertion via the Signos app. The removal and next insertions will also be recorded in the app.
The Dexcom sensor at times may cause false high sensor readings (glucose is not affected) if higher than the maximum dose (e.g. greater than 1 gram every 6 hours) of acetaminophen (the ingredient in Tylenol) is used. Therefore, you should not use a higher than the maximum dose (e.g. greater than 1 gram every 6 hours) of acetaminophen and medications containing acetaminophen for at least 24 hours before sensor insertion and while the sensor is being used. You can take the standard or maximum dose of acetaminophen of 1 gram (1,000 mg) every 6 hours and still use the Dexcom CGM. Please update your information in the mHealth app if you are taking acetaminophen- containing medicine for a short interval. During the course of the study, study team will integrate CGM data to other information (e.g. basic demographics, activities, identification and withdrawal of food using a variety of techniques such as gross pictures, motivational tools, coping skills to avoid comfort eating and white noise etc.) that are standard features of the Signos app. Amount of food, snacking panel, and some of the other features on the app are integrated to provide customized recommendations that motivate your engagement in a healthier lifestyle. Thus, your participation in this study requires the use of Dexcom CGM (glucose data) integration with diet, exercise, eating habits, water, food intake, sleep habits, etc. in the Signos adaptive algorithm. The app will provide you personalized recommendations for lifestyle changes. You will be suggested to implement changes in your daily habits for optimal weight optimization using various rewards and incentives. You will have the option to take this weight optimization program with your friends and family as fostering camaraderie, encouraging fitness activities, and promoting healthier habits encourage retentive performance. You will also have the option to invite your friends and create competitive requests to work together in achieving goals toward weight optimization. Program participants will have the option to work out together, swap healthy recipes, and talk about their goals. Consider creating long-term initiatives, such as running groups, healthy cooking classes, or yoga, bets, clubs, that will help participants extend their health success long after the challenge ends.
What are the options if you do not want to take part in this study? Your participation in this study is voluntary. You do not have to be in this study if you do not want to, and you can leave the study at any time. You will not be subject to any penalties or lose any services, benefits, or rights to which you would be otherwise entitled if you chose not to be in the study or if you leave the study early. Your alternative to being in this study includes participate in structured medical or activity weight loss programs.
What are the risks involved with being enrolled in this study? Risk of Drinking Glucose (Sugar Water): About one out of ten people have mild nausea or an upset stomach with the glucose (sugar) drink that is given during the oral glucose test. Rarely some people may experience a reaction (symptoms like nervousness or sweating) at the end of the test. You will be asked to keep a snack handy and available to guard against this. This test is not a requirement of study participation.
Increasing the blood sugar level rapidly may cause a warm sensation all over, lasting a few seconds.
