Summary

This trial is investigating the use of sirolimus to reduce the number of colon polyps in patients with Cowden syndrome over a 1 year period.

Who is the study for?
This trial is for adults over 18 with Cowden syndrome or related disorders, who have a genetic mutation called PTEN and more than 50 colon polyps that can't be removed endoscopically. It's not for those with chronic kidney disease, past high-grade colon tumors, colectomy history, or current/pending pregnancy.
What is being tested?
The study tests Sirolimus on patients with Cowden syndrome to see if it reduces the number of colon polyps over one year. Participants must have many polyps and a specific genetic mutation linked to their condition.
What are the potential side effects?
Sirolimus may cause side effects such as mouth sores, increased risk of infection, rash, diarrhea, abnormal blood test results (like elevated cholesterol), and potentially lung problems.

Trial Design

1Treatment groups
Experimental Treatment
Group I: Treatment armExperimental Treatment1 Intervention
There will be a clinic visit and colonoscopy at study entrance with standard of care sampling and assessment of polyps, including resection of concerning polyps. The investigators will also collect data on well-being via the SF-36 health survey (a validated questionnaire to help monitor this aspect given anecdotal patient-level reports of improvement while on therapy). Study subjects will then begin sirolimus 2 mg by mouth daily for 1 year. Laboratories will be checked at 4 days after initiation, at 2 weeks after initiation, then every 4 weeks for 3 months, then every 3 months to complete the year of therapy Participants will have a clinic visit at 3, 6 and 9 months and include well-being assessment with the SF-36 health survey. Participants will have a clinic visit with well-being assessment and perform colonoscopy at study closure at 12 months. The investigators will perform standard of care sampling and assessment of polyps, including resection of concerning polyps.
