Study of Triheptanoin for Treatment of Long-Chain Fatty Acid Oxidation Disorder

Humans eat long-chain fat in their diet and use it for energy during exercise and during periods of fasting. Patients with long-chain fatty acid oxidation disorders cannot use dietary fat for energy. They sometimes develop muscle breakdown, and severe pain with exercise or illness. They can also develop a heart that does not function properly. These patients are tired and expend less energy than people who do not have a long-chain fatty acid oxidation disorder. However, they can use a supplement oil called medium chain triglyceride or MCT. This study will determine if a new experimental oil called Triheptanoin can decrease the muscle pain and increase the heart function and the amount of energy in patients with long-chain fatty acid oxidation disorders.
