    12 years of age, we will utilize the national kidney disease education program (NKDEP) calculator (http://www.nkdep.nih.gov/lab-evaluation/gfr-calculators/children-conventional-unit.shtml).

The patient will not be excluded if 2 subsequent urine specimens are negative for hematuria as defined by the AUA.

    20. Proteinuria (1+ protein on urinalysis) unless evaluated and classified as benign by patient s primary medical provider or by NIH nephrology consult or in the context of normal urine protein creatinine ratio and in the absence of clinical symptoms (edema, hypertension).

    21. Active pulmonary disease, oxygen requirement or clinically significant history of decreased blood oxygen saturation, pulmonary therapy, or requiring active suction.

    22. Patients unable to complete a behavioral audiologic evaluation including pure-tone threshold assessment (500 Hz to 8000 Hz) to monitor for ototoxicity and for whom otoacoustic emissions (OAEs) cannot be reliably obtained at baseline.

    23. Patients with ongoing seizures, that are not stable in frequency, type or duration over a 2 month period prior to enrollment, requiring change in dose of antiepileptic medication (other than adjustment for weight) over a 2 month period prior to enrollment, or requiring 3 or more antiepileptic medications to control seizures.

    24. Patients, who in the opinion of the investigators are unable to comply with the protocol or have specific health concerns that would potentially increase the risk of participation.

5. Study Description

Brief Summary
Background: - Hydroxypropyl beta cyclodextrin (HPBCD) is being tested for a disease called Niemann-Pick disease type C1 (NPC1). NPC1 is a genetic disorder that results in gradual loss of nervous system function. Cholesterol and other fats have trouble moving out of the brain cells, which makes the cells work poorly and leads to symptoms. There is no treatment currently approved in the US for NPC1. Researchers want to test if it is safe to use HPBCD for NPC1. They want to see if it can help brain cells process cholesterol better. Objectives: - To test the safety and effectiveness of HPBCD for NPC1. Eligibility: - Individuals between 2 and 25 years of age who have been diagnosed with NPC1 and who have not already received HPBCD in an attempt to treat NPC1. Design: Participants will be screened with a physical exam and medical history. They will provide blood and urine samples for screening. They will also have neurological tests, including tests of hearing, speech and movement. Participants will have a lumbar puncture (also called a spinal tap) every month to deliver the drug to the spinal fluid that surrounds the brain. The length of the trial will be determined by the safety and efficacy information that is obtained. Treatment will be monitored with frequent blood and urine tests, cerebral spinal fluid tests, hearing and neurological exams.
Detailed Description
Niemann-Pick disease type C (NPC) is a lethal, autosomal recessive, lysosomal storage disorder characterized by neurodegeneration in early childhood and death in adolescence. The causative genes NPC1 (about 95% of cases) and NPC2 (about 5% of cases) are involved in the intracellular trafficking of lipids and cholesterol. Mutations on either of these genes lead to progressive accumulation of unesterified cholesterol and other lipids in the central nervous system (CNS). The National Institutes of Health (NIH) Therapeutics for Rare and Neglected Diseases (TRND) program is developing 2-hydroxypropyl-Beta-cyclodextrin (HP-Beta-CD) for the treatment of patients with Niemann-Pick disease type C1 (NPC1) to slow progression of symptoms of the disease. In this Phase 1, non-randomized, open-label, single-center, study, we propose to administer HP-Beta-CD intrathecally via lumbar injection to drug naive cohorts of 3 patients at doses of 200 mg escalated to 300, 400 mg and 900 mg. Subsequent dose escalations may occur in increments of up to 300 mg. The objectives of this study are to assess the safety, tolerability, feasibility, and pharmacokinetics (PK) of intrathecally (IT) administered HP-Beta-CD to NPC1 patients, to determine an active dose of HP-Beta-CD as measured by changes in plasma 24-(S) hydroxycholesterol (24(S)-HC) concentration, and to evaluate the use of biomarkers and potential clinical outcomes of NPC1. All patients in the cohort will receive HP-Beta-CD (n = 3) once monthly for at least two doses, and the decision to dose-escalate will be based on safety and on biochemical data. Safety will be assessed by adverse events (AEs), audiologic evaluation, clinical laboratory tests, vital signs, physical examinations, chest X-rays and electrocardiograms (ECGs). Biochemical efficacy will be measured by change from baseline in plasma 24(S)-HC. PK will be assessed for plasma HP-Beta-CD.
