Summary

Brief summary (as posted)

This is a study to determine if a certain drug, called telotristat ethyl (Xermelo®), can help reduce the chance of blood pressure and heart rate variations (known as carcinoid crisis) in individuals who have neuroendocrine tumors (also called carcinoid tumors). These complications can be life-threatening for patients who already have to experience challenging surgeries to remove their tumors. To determine if telotristat ethyl (Xermelo®) will help reduce these complications during surgery, researchers will give the drug to study participants before surgery.

type
EXPERIMENTAL
label
Telotristat Ethyl (Xermelo®)
description
After the surgery is performed, study participants will stop taking telotristat ethyl (Xermelo®) as part of this study and there will be no follow-up visits or calls required outside of the usual postoperative care. The research team will collect clinical data on the participants' outcomes up to 30 days after surgery by accessing medical records.

description
To determine if surgical treatment with telotristat ethyl reduces the incidence of carcinoid crisis during surgery for participants with small bowel neuroendocrine tumors by comparing data from this study to data from previous research.

Eligibility

Sex: All
Minimum age: 18 Years

Show eligibility criteria text

Inclusion Criteria:

* Patients must have a grade 1 or grade 2 small bowel, neuroendocrine tumor (NET) that has been medically confirmed by a physician.
* Patients who plan to have abdominal (stomach) surgery due to cancer that has spread to their liver. Patients must voluntarily choose to have surgery.
* 18 years old or older.
* Patients with small bowel neuroendocrine tumors who are asymptomatic (not showing symptoms) but have elevated serotonin or 5-HIAA (5-hydroxyindoleacetic acid) levels before surgery.
* Patients who are symptomatic (showing carcinoid symptoms) and have elevated or normal Serotonin or 5-HIAA levels (plasma or urinary) before surgery.

Exclusion Criteria:

* Patients belonging to vulnerable populations such as children and prisoners.
* Patients with grade 3 neuroendocrine tumors or neuroendocrine tumors that are hard to identify.
* Patients with untreated carcinoid heart disease.
* Patients who are receiving any other drugs or treatment as part of a research study.
* Patients with a "currently active" second tumor other than non-melanoma skin cancers. Patients are not considered to have a "currently active" tumor if they have completed therapy and are free of disease for 3 or more years.
* Patients with known brain cancers.
* Patients who have a history of allergic reactions to medications that have similar chemical or biologic ingredients as those found in telotristat ethyl.
* Uncontrolled illness that occurs while having cancer such as, but not limited to, ongoing or active infection, congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit the patient's ability to follow study requirements.
* Pregnant women are excluded from this study because telotristat ethyl can severely damage an embryo/fetus or cause an abortion. Because the drug also poses unknown, potential risks for nursing infants, breastfeeding should be discontinued if the mother is treated with telotristat ethyl.
* Women of childbearing age who refuse to take a urinary pregnancy test and refuse to use an acceptable method of birth control during the time of the study and for at least 7 days after surgery. Acceptable contraception includes barrier method (male or female condom); hormonal (oral or implantable); documented sterilization procedure; cap, diaphragm, or sponge with spermicide; or abstinence as a lifestyle choice.
* Patients on CYP3A4 substrates that cannot be stopped due to medical concerns for 15 days prior to surgery.
* Patients with moderate or severe liver failure.
