Official title

The Effect of Oral Magnesium Pidolate on Incidence of Painful Crises in Patients With Hemoglobin SC Disease

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Subjects have a form of sickle cell disease, called hemoglobin SC disease. This results in abnormally shaped red blood cells that get 'stuck' in blood vessels and then results in episodes of severe pain (pain crises). Patients with the more common form of sickle cell disease, called hemoglobin SS disease, also suffer from pain crises. Treatment with the drug hydroxyurea is available to help prevent the pain crises in hemoglobin SS disease, but there is no good treatment to help prevent the pain crises in hemoglobin SC disease. It has been shown that one of the reasons for the formation of the abnormally shaped red blood cells in patients with SC disease is the fact that these cells do not contain enough water; they are dehydrated. Drinking more water will not increase the amount of water in the cells. Certain salts and minerals can however have an effect on the amount of water in the red blood cells. One of the most important minerals influencing this is called magnesium. Magnesium is present in food and also in certain medications used to treat heartburn. Magnesium has been used successfully both in animals and people to increase the amount of water in the red blood cells and is very well tolerated by most people. Investigators are using a new form of magnesium known as magnesium pidolate because this form of magnesium may help with the symptoms of disease without causing diarrhea (a common side effect of magnesium products). Purpose The purpose of this study is to find out whether treatment with magnesium pidolate will increase the amount of water in the red blood cell and result in fewer painful crises in patients with hemoglobin SC disease while not causing diarrhea. The study will last for about 64 weeks (about 16 months).
