Brief Summary:
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 Funding source - FDAs OOPD
Detailed Description:
Recruitment Patients with a long-chain fatty acid oxidation disorder will be recruited through our clinic past research participants a patient support website and recruitment letters mailed to physicians around the US We will enroll 16 subjects at OHSU and 16 subjects at the University of Pittsburgh age 7 to 40 with a disorder in fatty acid oxidation
Procedures Subjects will be admitted to the clinical research center for 4 days They will collect all their urine for 24 hours Heart function will be measured using ultrasound an electrocardiogram ECG The motion of the heart will be measured by magnetic resonance imaging MRI For this test the patient lies in the magnetic field of the MRI machine in the Advanced Imaging Resource Center AIRC for about 45 minutes The amount of muscle and fat in the whole body and inside the liver and muscle will be measured by MRS and by dual X-ray absorptiometry DEXA Subjects will walk on a treadmill for about 45 minutes The amount of Calories they use their heart rate and if they burn fat or carbohydrates will be measured Blood samples will be collected before and after exercise A meal test will be used to determine how much fat they burn The subjects will drink a liquid breakfast with a stable isotope labeled fat in the breakfast Breath and blood samples will be collected before and after the meal The amount Calories burned by each subject will be measured when they are at rest on a bed by indirect calorimetry The amount of Calories burned by subjects when they are doing their routine daily activities will be measured at home by doubly labeled water All of these tests will be done at baseline Then subjects will be randomly assigned to consume MCT current standard of care or triheptanoin at 20 of their estimated Calorie needs for 4 months The subject andor the parent will be taught how to use the supplement oil in their diet for cooking and baking The subject will be sent home and the oil will be shipped to their home The study coordinator will call the subject or subjects guardian each week to monitor the subjects diet potential side effects and assist with diet planning At the end of 4 months all of the baseline tests will be repeated
Triheptanoin is experimental oil It is a clear odorless oil that can be mixed with foods and used in cooking Almost all oils are made from even chains of carbon molecules Triheptanoin is different because the carbon chains are odd in number The co-investigator of this study at the University of Pittsburgh Dr Jerry Vockely holds an IND for the prescription and use of triheptanoin in humans IND 106011
Data Analysis The change in exercise ability heart function Calories used and body fat after 4 months will be compared between subjects randomized to MCT versus triheptanoin
