Testing Obeticholic Acid for Familial Adenomatous Polyposis

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

This phase IIa trial investigates if giving obeticholic acid (OCA) is safe and has a beneficial effect on the number of polyps in the small bowel and colon in patients with familial adenomatous polyposis (FAP). FAP is a rare gene defect that increases the risk of developing cancer of the intestines and colon. OCA is a drug similar to a bile acid the body makes. It is fluid made and released by the liver. OCA binds to a receptor in the intestine that is believed to have a positive effect on preventing cancer development. OCA has been effective in treating primary biliary cholangitis (PBC), a liver disease, and is approved by the Food and Drug Administration (FDA) for use at a lower dose (10 mg). There have been studies showing that OCA decreases inflammation and fibrosis. However, it is not yet known whether OCA works on reducing the number of polyps in patients with FAP.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Ages Eligible for Study:18 Years
Sexes Eligible for Study:ALL
Accepts Healthy Volunteers:No
Standard Ages:ADULT, OLDER_ADULT
Inclusion CriteriaExclusion Criteria
  1. * Participants must have a diagnosis of phenotypic FAP with disease involvement of the duodenum and rectum as defined by:
  2. * Genetic diagnosis: APC germline mutation (with or without family history) or obligate carrier
  3. * Clinical diagnosis: FAP phenotype with \> 100 adenomas in large intestine and participant has a family history of FAP
  4. * Clinical diagnosis: FAP phenotype who are status post colectomy for polyposis, participant has a family history of FAP, and 2 FAP experts agree to the diagnosis
  5. * Attenuated FAP diagnosis: APC germline mutation required
  6. * Participants must have no evidence of active or recurrent invasive cancer for 6 months prior to screening and must be at least 6 months from any prior cancer-directed treatment (such as surgical resection, chemotherapy, immunotherapy, hormonal therapy or radiation)
  7. * Age \>= 18 years. Because no dosing or adverse event (AE) data are currently available on the use of OCA in participants \< 18 years of age, children are excluded from this study but will be eligible for future pediatric trials, if applicable
  8. * Eastern Cooperative Oncology Group (ECOG) performance status =\< 1 (Karnofsky \>= 70%)
  9. * Hemoglobin \>= 10 g/dL or hematocrit \>= 30%
  10. * Leukocyte count \>= 3,500/microliter
  11. * Platelet count \>= 100,000/microliter
  12. * Absolute neutrophil count \>= 1,500/microliter
  13. * Creatinine clearance (calculated if measured is not available) \>= 30 mL/min/1.73m\^2
  14. * Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase \[SGOT\])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase \[SGPT\]) =\< 1.5 x the institutional upper limit of normal (ULN)
  15. * Total bilirubin =\< 1.0 x ULN
  16. * Alkaline phosphatase =\< 1.5 x ULN
  17. * Gamma-glutamyl transferase (GGT) =\< 1.5 x ULN
  18. * Presence of Spigelman stage II or III duodenal polyposis at screening
  19. * Presence of intact rectum or ileo-rectal anastomosis (IRA) or ileal pouch-anal anastomosis (IPAA) or end ileostomy
  20. * Participants must have a negative test result for human immunodeficiency virus (HIV); if tested within the past 6 months, result will be accepted without repeating the test
  21. * Participants must have negative test for hepatitis C virus (HCV) and B virus (HBV)
  22. * Willing and able to adhere to the prohibitions and restrictions specified in the final approved protocol
  23. * The effects of OCA on the developing human fetus at the recommended therapeutic dose are unknown. For this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, throughout the duration of study participation, and for at least 6 months after receiving the last dose of study drug. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her study physician immediately
  24. * Willingness to moderate alcohol intake (consuming no more than 1 or 2 alcoholic drinks per day for women and men, respectively)
  25. * Ability to understand and the willingness to sign a written informed consent document
  1. * Prior use of study drug
  2. * Duodenal or rectal/pouch polyp burden that is not quantifiable
  3. * Histologically-confirmed high-grade dysplasia or cancer on biopsy at screening
  4. * Individuals with active, known or suspected chronic liver disease including cirrhosis, nonalcoholic steatohepatitis (NASH) with liver fibrosis, NASH with cirrhosis, primary sclerosing cholangitis, biliary atresia
  5. * Individuals with acute cholecystitis (defined by a syndrome of right upper quadrant pain, fever, and leukocytosis associated with gallbladder inflammation)
  6. * Individuals with a history of pancreatitis or presence of pancreatic abnormalities suggestive of increased risk of pancreatitis
  7. * Individuals with hepatic steatosis and velocity \> 1.7 meters/second (m/s) as determined by liver ultrasound elastography
  8. * Individuals with hyperlipidemia not well controlled with the use of pharmacotherapy and/or dietary modifications
  9. * History of severe, progressive, or uncontrolled renal, genitourinary, hepatic, hematologic, endocrine, cardiac, vascular, pulmonary, rheumatologic, neurologic, psychiatric, or metabolic disturbances, or signs and symptoms thereof
  10. * Pregnant, breast-feeding, or women of childbearing potential unwilling to use a reliable contraceptive method. Pregnant women are excluded from this study because OCA is an agent with unknown effects on the developing human fetus. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with OCA, breastfeeding should be discontinued if the mother is treated with OCA
  11. * Known hypersensitivity, allergies, or intolerance to the study drug or compounds of similar chemical or biologic composition
  12. * Any serious and/or unstable pre-existing medical disorder (aside from malignancy exception above), psychiatric disorder, or other conditions that could interfere with participant's safety, obtaining informed consent, or compliance to the study procedures
  13. * Participants may not be receiving any other investigational agents
  14. * Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
  15. * Individuals with active and untreated hepatitis C virus (HCV) and/or or hepatitis B virus (HBV) infection

  17. * CD4+ count \>= 300/uL
  18. * Viral load is undetectable

  22. * Investigational agents
  23. * Bile acid sequestrants (bile acid binding resins): cholestyramine, colestipol, or colesevelam
