Overnight Feeding Study in Glycogen Storage Disease Type 1
Switzerland5 participantsStarted 2013-11
Plain-language summary
In this clinical cross-over study, we will compare the efficacy of different oral nutrition regimens for night-time glucose control in adult GSD 1 patients. Three different over-night nutrition regimens (=interventions) will be compared in each patient sequentially, (1) uncooked corn starch (UCSS, "Maizena"), (2) modified corn-starch, (3) other carbohydrate (starch) containing meal. During each intervention, glucose profiles will be continuously monitored by continuous glucose monitoring (CGMS). The duration of each intervention is 3d (mimimum) to 6d (maximum), depending on the quality of night-time glucose control and the technical quality of glucose sensor readings. Between the interventions, the patients follow their normal prescribed diet.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion criteria:
* Glycogen storage disease type 1 (type 1a and 1b)
* Stable nighttime glucose control without frequent or severe hypoglycaemia under current dietary treatment, according to capillary glucose measurements.
Exclusion criteria:
* Unstable night-time glucose control during the last 8 weeks with frequent (\> 4x weekly) hypoglycaemia during night-time, or a hospitalisation due to unstable glucose control during the last 4 weeks, or any episode of severe hypoglycaemia (requiring assistance or loss of consciousness) during the last 4 weeks.
* Pregnancy or breast feeding
* Drug or alcohol abuse
* Acute gastrointestinal problems (e.g. acute gastroenteritis)
* Known malignancy (e.g. hepatocellular carcinoma)
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring

Maximum fasting time over-night (h)
Timeframe: Maximum fasting time will be measured during each dietary intervention for an average period of 3d (minimum) to 6d (maximum)
