The Use of Uncooked Sweet Manioc Starch to Treat Hepatic Glycogen Storage Diseases

Brazil11 participantsStarted 2017-04-29

Plain-language summary

Hepatic Glycogen Storage Diseases are a group of 10 serious genetic diseases that present in childhood and are characterized more frequently by the occurrence of repetitive hypoglycemia and dyslipidemia. Regarding treatment, the most commonly used strategy is the frequent administration of uncooked cornstarch, in average, every 4 hours. Although this treatment is successful, the use of large amounts of cornstarch can lead to overweight and, especially, to the decrease in the quality of life of patients and caregivers, due to the need to use the starch during the night. The search for a treatment that is widely available and that can lead to the prolongation of the fasting time, can collaborate to improve the care of these patients. The main scientific question to be answered by this research is: does sweet manioc starch, a Brazilian product, safely prolong the fasting time (with normoglycemia) of the patients as already suggested in experimental models? Main objective: To evaluate the efficacy and safety of the use of uncooked Sweet Manioc Starch in the treatment of patients with hepatic Glycogen Storage Diseases, using as model the Glycogen Storage Diseases type Ia.

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?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

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.
