2 Clinical Trials for Various Conditions
Background: * High density lipoprotein (HDL), or good cholesterol, moves cholesterol from the artery walls back to the liver. A blood enzyme known as LCAT maintains HDL levels and helps it remove cholesterol from the body. Familial LCAT deficiency (FLD) is a genetic disease that results in low levels or total absence of LCAT. People with FLD often have kidney problems, and may develop kidney failure. Researchers think that the clinical problems of FLD can be prevented or even reversed by replacing the defective enzyme. * There are no drugs that increase LCAT. It has to be artificially made and infused into the body. The artificial LCAT is called recombinant human LCAT, or ACP-501. Researchers want to see how well it works in one person with FLD and poor kidney function. Objectives: - To see whether ACP-501 can improve the symptoms of FLD. Eligibility: - One person (the study participant) with FLD. Design: * The participant will be screened with a physical exam and medical history. Blood samples will be collected. * The participant will receive ACP-501 and remain in the hospital for 24 hours for regular blood tests. The participant may stay in the hospital or return for daily clinic visits until it is time for the next dose. The second dose will be given on Day 4 or Day 8. * If an optimal dose has not yet been identified, a third dose will be given 7 days after the second dose. * The participant will then go home, but must return to the hospital for ACP-501 infusions and blood tests every 1 or 2 weeks, as needed. Every 3 months, the participant will have a full clinic visit with blood tests and other studies.
The purpose of the LCAT (Lecithin cholesterol acyl transferase) Natural History Study (LCAT NHS) is to help identify people with a mutation in a gene called LCAT, collect and store information about their medical history and disease course, and to assess for associations and follow changes in clinical features and biomarkers of disease. This information will help health care providers better understand the natural history of disease of LCAT deficiency. Study staff will collect information from previous clinical visits such as lab tests, physical exam findings, renal and cardiovascular imaging, findings from kidney biopsies and eye exams, and medication and other treatments. As part of this study the investigators are asking participants permission to reach out to their doctors to obtain medical records and stored samples (such as serum or plasma or biopsies) from past visits. Participants may also be asked to join a web-based patient portal to complete a patient-outcomes survey. As part of this study, participants will also be asked to do the following things at different times: * Answer questions about: * Demographic information (year of birth, age, gender, race/ethnicity, country) * LCAT deficiency diagnosis such as year of diagnosis, type of diagnosis (clinical, genetic), genotype information/LCAT mutation status * Medical history and family history and any updates * A review of medications If participants are able to come to a study visit in person the following may happen: Physical examination including vital signs (height, weight, blood pressure, and heart rate) Urine and blood samples for laboratory testing. participants will be required to fast for 10 hours before the blood tests. A small blood sample may also be taken 2-4 hours after a meal. * The following will be tested: the different types of cholesterol and other fats in the blood (lipids), standard hematology (type and number of blood cells), blood chemistries such as sodium, potassium, and calcium, thyroid function, liver panel (function of the liver), kidney function and the level of protein in urine * Blood and urine samples may also be stored for future testing * Genetic material will be collected * Blood cells may be stored for future research * Participants will have approximately 4.5 tablespoons of blood drawn annually. * If not done previously, participants will complete an eye exam. * Participants may be seen by a doctor specialized in renal disease
