Tezacaftor/Ivacaftor in Subjects with Cystic Fibrosis and F508del/F508del-CFTR or F508del/G551D-CFTR.
RATIONALE Tezacaftor (formerly VX-661) is an investigational small molecule that improves processing and trafficking of the cystic fibrosis transmembrane conductance regulator (CFTR) in vitro, and improves CFTR function alone and in combination with ivacaftor. OBJECTIVES To evaluate the safety and efficacy of tezacaftor monotherapy and of tezacaftor/ivacaftor combination therapy in subjects w...
متن کاملcystic fibrosis with a unusual presentation in monozygotic twins
cystic fibrosis is an inheritant autosomal recessive disease. it is associated with mutations in cystic fibrosis trans regulator gene (cftr) and has different presentations.we report two 2 month old female patients, products of a twin delivery presented with anemia, edema, hypoalbuminemia and pneumonia.after some work ups, diagnosis of cystic fibrosis was confirmed. this is an uncommon and inte...
متن کاملLumacaftor/ivacaftor in patients with cystic fibrosis and advanced lung disease homozygous for F508del-CFTR.
OBJECTIVE Evaluation of the safety, tolerability, and efficacy of lumacaftor/ivacaftor in patients with cystic fibrosis (CF) with severe lung disease. METHODS Patients with CF 12 years of age and older, homozygous for F508del-CFTR, with percent predicted forced expiratory volume in 1 second (ppFEV1) <40 received lumacaftor 400 mg/ivacaftor 250mg every 12h (full dose) for 24weeks in an open-la...
متن کاملThe magnitude of ivacaftor effects on fluid secretion via R117H-CFTR channels: Human in vivo measurements
We optically measured effects of orally available ivacaftor (Kalydeco®) on sweat rates of identified glands in 3 R117H subjects, each having a unique set of additional mutations, and compared them with 5 healthy control subjects tested contemporaneously. We injected β-adrenergic agonists intradermally to stimulate CFTR-dependent 'C-sweat' and methacholine to stimulate 'M-sweat', which persists ...
متن کاملDecoding F508del Misfolding in Cystic Fibrosis
The functional deficiency of the cystic fibrosis transmembrane conductance regulator (CFTR), a plasma membrane chloride channel, leads to the development of cystic fibrosis. The deletion of a phenylalanine at residue 508 (F508del) is the most common cause of CFTR misfolding leading to the disease. The F508del misfolding originates in the first nucleotide-binding domain (NBD1), which induces a g...
