Kalydeco (Ivacaftor) - Summary

 
 



KALYDECO SUMMARY

The active ingredient in KALYDECO tablets is ivacaftor.

KALYDECO is classified as a cystic fibrosis transmembrane conductance regulator (CFTR) potentiator. KALYDECO is indicated for the treatment of cystic fibrosis (CF) in patients age 6 years and older who have a G551D mutation in the CFTR gene. If the patient's genotype is unknown, an FDA-cleared CF mutation test should be used to detect the presence of the G551D mutation.

Limitations of Use

KALYDECO is not effective in patients with CF who are homozygous for the F508del mutation in the CFTR gene and has not been studied in other populations of patients with CF.

Clinical Trials Related to Kalydeco (Ivacaftor)

Short Term Effects of Ivacaftor in Non-G551D Cystic Fibrosis Patients [Recruiting]
This is a study of the short-term effects of ivacaftor on sweat chloride concentration and lung function in cystic fibrosis (CF) patients who fall outside current FDA approval. This new, first of its kind drug is approved for use only in CF patients with the G551D mutation in whom it safely confers considerable benefits. However, it is highly likely that CF patients with many other mutations can benefit similarly from this drug, some of whom can be identified by phenotype or genotype. We will enroll up to 30 CF subjects with clinical presentations in which there is one or more signs of residual CF channel function. The signs of residual function include: normal digestion, concentration of chloride in sweat between 55 and 85, or milder than expected CF disease in a CF patient with severe gene mutations. The primary outcome measure will be the difference in sweat chloride concentration measured in subjects on placebo and on ivacaftor. Secondary outcome measured will be lung function.

Study of Ivacaftor in Cystic Fibrosis Subjects 2 Through 5 Years of Age With a CFTR Gating Mutation [Completed]
The 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.

Safety Study of Ivacaftor in Subjects With Cystic Fibrosis [Completed]
The purpose of this study was to evaluate the safety and tolerability of ivacaftor in patients with cystic fibrosis (CF) who were aged 18 years or older and have a G551D mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. Ivacaftor is a potent and selective CFTR potentiator of wild-type, G551D, F508del, and R117H forms of human CFTR protein. Potentiators are pharmacological agents that increase the chloride ion transport properties of the channel in the presence of cyclic AMP-dependent protein kinase A (PKA) activation.

Study of Ivacaftor in Subjects With Cystic Fibrosis (CF) Who Have the R117H-CF Transmembrane Conductance Regulator (CFTR) Mutation (KONDUCT) [Completed]
The purpose of this study is to evaluate the efficacy and safety of ivacaftor in subjects with cystic fibrosis (CF) who have the R117H-CFTR mutation.

(Study: Vertex IIS) Does Ivacaftor Alter Wild Type CFTR-Open Probability In The Sweat Gland Secretory Coil? [Recruiting]
Clinical studies of lumacaftor + ivacaftor (combo therapy) produced better FEV1 (forced expiratory volume in 1 second) improvements than ivacaftor alone, without further improvement in sweat chloride results. To help understand why sweat chloride was unresponsive, the investigators will use a newly developed sweat secretion test that provides accurate, in vivo readout of CFTR (cystic fibrosis transmembrane conductance regulator) function in the sweat gland secretory coil. The investigators devised a protocol to determine if short courses of ivacaftor (3. 5 days) will produce significant increases in WT (Wild-Type, i. e. normal) CFTR open probability by measuring CFTR-dependent sweating (C-sweat) in subjects with WT CFTR.
