Official title

An Open-label, Single Center Study Assessing Tenapanor as a Non-CFTR-mediated Treatment of CF-related Constipation in People With CF.

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Tenapanor is the newest FDA-approved drug for IBS with constipation (IBS-C). This study seeks to understand tenapanor as a treatment for cystic fibrosis-related constipation (CFrC) in CF patients. Participants will ingest one 50 mg tablet of tenapanor, twice daily, for a 4-week treatment period. They will also complete three questionnaires, the PAC-SYM, PAC-QoL, and IBS-SSS, and daily diaries to characterize GI symptom burden and spontaneous bowel movement (SBM) frequency.
