Summary
This trial looks at the effects of taking either plecanatide or linaclotide on a chemical in the small intestine, and how they compare to not taking either drug.
Who is the study for?
This trial is for adults over 18 who are not pregnant or breastfeeding, agree to use contraception, and have an ECOG performance status of <=1. They must be scheduled for an esophagogastroduodenoscopy (EGD), willing to provide biospecimens, and haven't used GCC agonists or investigational agents recently.
What is being tested?
The study examines the effects of two FDA-approved constipation drugs, plecanatide or linaclotide, on a chemical in duodenal tissue from the small intestine compared to no drug treatment. Participants will undergo biospecimen collection including biopsy during EGD.
What are the potential side effects?
While specific side effects aren't listed here, plecanatide and linaclotide can generally cause diarrhea, abdominal pain, swelling or bloating. Allergic reactions may occur if sensitive to similar compounds.
