Study of Ivacaftor in Cystic Fibrosis Subjects 2 Through 5 Years of Age With a CFTR Gating Mutation...
Cystic FibrosisThe purpose of this study is to evaluate the safety, pharmacokinetics (PK), and pharmacodynamics (PD), of ivacaftor in children with cystic fibrosis (CF) who are 2 through 5 years of age and have a CF Transmembrane Conductance Regulator (CFTR) gating mutation in at least 1 allele. Part A is designed to evaluate the safety and PK of multiple-dose administration of ivacaftor in participants 2 through 5 years of age and to confirm the doses for Part B. Part B is designed to evaluate the safety, PK, PD, and efficacy of ivacaftor in participants 2 through 5 years of age.

Predictive Value of PIIINP Urinary for the Development of Chronic Renal Failure in Patients With...
Lung TransplantationCystic Fibrosis1 moreChronic renal failure is a serious complication of lung transplantation especially in patients with cystic fibrosis. Their medical history prior to the Lung Transplantation has already exposed to kidney damage. Post-lung transplantation, these patients are subjected to renal toxicity anticalcineurins they receive large doses. The measurement of renal function of patients by formula to estimate GFR in routine use is unreliable and other markers seem indispensable. The purpose of this study is to evaluate two markers, PIIINP (Procollagen III aminoterminal peptide N), whose urinary levels was correlated to the intensity of fibrosis in different types of kidney disease.

Metabolic Efficiency of Combined Pancreatic Islet and Lung Transplant for the Treatment of End-Stage...
Cystic FibrosisDiabetes Related Cystic Fibrosis1 morePatients with end-stage cystic fibrosis (CF) and severe CF-related diabetes (CFRD) may benefit from combined lung-pancreatic islet transplantation. A recent case series showed that combined bilateral lung and pancreatic islet transplantation is a viable therapeutic option for patients with end-stage CF and CFRD. The use of different organs from a single donor may lead to reduced immunogenicity. As the prevalence of CFRD has increased dramatically with the improved life expectancy of patients with CF, islet transplantation should be considered at the end-stage CF. By restoring metabolic control, the investigators hypothesize that islet transplantation may improve the management of CF patients undergoing lung transplant and decrease the complication rate in the early postoperative period.

Inhaled Vancomycin Tolerability, Safety and Pharmacokinetics
HealthyCystic FibrosisThe study is carried out to evaluate the safety, tolerability and pharmacokinetics of AeroVanc inhalation powder in healthy volunteers, and in patients with cystic fibrosis.

Persistent Methicillin Resistant Staphylococcus Aureus Eradication Protocol (PMEP)
Cystic FibrosisThe prevalence of methicillin resistant Staphylococcus aureus (MRSA) respiratory infection in Cystic Fibrosis (CF) has increased dramatically over the last decade. Evidence suggests that persistent infection with MRSA may result in an increased rate of decline in Forced Expiratory Volume (FEV)1 and shortened survival. Currently there are no conclusive studies demonstrating an effective aggressive treatment protocol for persistent MRSA respiratory infection in CF. Data demonstrating an effective and safe method of clearing persistent MRSA infection are needed. The purpose of this study is to evaluate the safety and efficacy of a 28-day course of vancomycin for inhalation, 250 mg twice a day, (in combination with oral antibiotics) in eliminating MRSA from the respiratory tract of individuals with CF and persistent MRSA infection. Subjects will be assigned in a 1:1 ratio to either vancomycin for inhalation (250 mg twice a day) or taste matched placebo and will be followed for 3 additional months. In addition, both groups will receive oral rifampin, a second oral antibiotic (TMP-SMX or doxycycline, protocol determined), mupirocin intranasal cream and chlorhexidine body washes. Forty patients with persistent respiratory tract MRSA infection will be enrolled in this trial.

Redox Imbalance and the Development of Cystic Fibrosis Diabetes
Diabetes MellitusType 21 moreCystic fibrosis-related diabetes (CFRD) occurs in almost 20% of teens and 50% of adults. The investigators' long term goal is to determine the cause of CFRD in order to translate this knowledge into therapies aimed at preventing CFRD. Since CFRD and type 2 diabetes share several clinical features and since oxidative stress is a key factor in the development of type 2 diabetes, the investigators explored the role of oxidative stress in CFRD. The investigators discovered a unique CF biochemical signature that they believe could be implicated in the development of CFRD. The investigators found that glucose ingestion in CF teens and young adults causes an acute and profound systemic redox imbalance to the oxidizing state. The degree of redox imbalance was quite severe and would be expected to damage the insulin producing cells as these cells are particularly vulnerable to oxidative stress. Thus, these findings could prove to be a critical factor in the pathogenesis of CFRD. This proposal will test the hypothesis that glucose-induced redox imbalance is an intrinsic, metabolic defect in CF. In addition, because CF people are required to consume a high calorie diet to maintain their weight, the investigators also hypothesize that certain high caloric foods will recapitulate the redox imbalance induced by ingesting glucose and thus hasten the development of CFRD. Specifically, the investigators aim to: Determine whether young children with CF have glucose-induced redox imbalance Determine whether eating a meal with a high glycemic index induces acute redox imbalance Determine whether commonly consumed beverages containing simple sugars (i.e., soda or fruit juice) induce acute redox imbalance

A Safety and Efficacy Trial of Inhaled Mannitol in Adult Cystic Fibrosis Subjects
Cystic FibrosisThis trial aims to provide prospective evidence of the safety and efficacy of mannitol 400 mg b.i.d. in subjects aged 18 years and above. We hypothesize that inhaled mannitol 400 mg b.i.d. will increase the mean change from baseline FEV1 (mL) compared to control over the 26-week treatment period in adult subjects with cystic fibrosis. Any improvement in FEV1 is considered clinically meaningful, however, this trial has set a threshold of 80 mL for the purposes of determining an appropriate sample size for statistical power while retaining trial feasibility in an orphan disease population

A Study of Lung Clearance After Hypertonic Saline Delivery Using the tPAD Device
Cystic FibrosisThe primary objective of this study is to determine whether a single overnight, eight-hour administration of a 7% NaCl solution delivered by the Parion Sciences transnasal Pulmonary Aerosol Delivery (tPAD) device has a significant effect on mucociliary clearance in subjects with cystic fibrosis, as compared to no treatment. This study will be conducted at the University of Pittsburgh Medical Center.
