Cystic Fibrosis Clinical Trial
Official title:
Gastrointestinal Outcome Measures Before and After Orkambi Therapy in Cystic Fibrosis (CF) Patients Carrying the F508del Mutation on Both Alleles
Ivacaftor caused a significance increase in weight in patients carrying the G551D mutation and the etiology of this has largely remained unknown but may be due to improved function of the gastrointestinal tract. The combination therapy of Orkambi has been recently approved for subjects with Cystic Fibrosis homozygous for F508del mutation. This provides an opportunity to examine if there are any improvements in gastrointestinal function. The investigators aim to investigate various aspects of gastrointestinal and pancreatic function before and 6 months after the commencement of Orkambi therapy.
To examine the entire intestinal mucosa via capsule endoscopy before and 6 months after
Orkambi therapy to ascertain if the inflammatory changes in the intestine have improved. A
marker of intestinal inflammation measured in the stool, Calprotectin, will be examined
before and 6 months after Orkambi treatment. The investigators hypothesize that the result
will be reduced on therapy.
A marker of pancreatic exocrine function, pancreatic elastase, will be examined before and 6
months after therapy to examine if the result has increased indicating improvement of
exocrine pancreatic function
Study Population All subjects with CF homozygous for the F508del mutation in Sweden eligible
for Orkambi therapy, i.e. above 12 years of age, in total 145 patients in Sweden of which 60
are taken care of at Stockholm CF Center; the investigators aim to examine 20 patients.
Study Duration The duration will be 6 months for each patient.
