Summary
This is a prospective, multicenter, observational study designed to collect gastrointestinal related data in patients with Cystic Fibrosis (CF).
Conditions
Cystic Fibrosis
Recruitment Status
Completed
Detailed Description
There are currently no large, multicenter prospective clinical trials examining management of constipation or other gastrointestinal (GI) symptoms in people with cystic fibrosis (CF). Current recommendations in the CF literature are largely based on expert consensus and opinions. Yet, constipation and other GI symptoms are crucial factors in quality of life (QOL) and maintenance of optimal nutritional state in people with CF. This study will use GI-symptomatology questionnaires to understand the multiple overlapping GI symptoms in people with CF. Eligible subjects will be consented and enrolled in the study at the Enrollment Visit. At the visit, the subject or parent/guardian will complete the patient reported outcome surveys (PROs) using a mobile device (e.g., smartphone or tablet). The same questionnaires will be completed on a mobile device outside the clinic three additional times. The PROs will consist of four questionnaires: Patient Assessment of Constipation Symptoms (PAC-SYM), Patient Assessment of Gastrointestinal Symptoms (PAGI-SYM), Patient Assessment of Constipation Quality of Life (PAC-QOL) and a disease-specific questionnaire (Bristol Stool Scale and questions about fecal incontinence, and stool quality and frequency).

Two well-characterized mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene
Abnormal nasal potential difference (NPD) (change in NPD in response to a low chloride solution and isoproterenol of less than -5 mV)
Enrolled in the Cystic Fibrosis Foundation Patient Registry (subjects may enroll in the Registry at Enrollment Visit if not previously enrolled)
Written informed consent (and assent when applicable) obtained from subject or subject's legal representative
Willing to complete questionnaires on mobile device
Able to use the Medidata Patient Cloud mobile application for completing the questionnaires
Exclusion Criteria:
Presence of a condition or abnormality that, in the opinion of the Investigator, would complicate interpretation of study outcome data or interfere with achieving the study objectives

Current gastrointestinal (GI) or abdominal/pelvic malignancy
Abdominal or pelvic surgery within the 28 days prior to the Enrollment Visit
At the time of the Enrollment Visit, planned abdominal or pelvic surgery or bowel cleanout in the 28 days after the Enrollment Visit
