Enterade in Carcinoid/Non-Carcinoid Syndrome Neuroendocrine Tumor Patients With Quality of Life Limiting Bowel Frequency

Inclusion Criteria: Carcinoid syndrome: Participants must have histopathologically confirmed neuroendocrine tumor with 4 or more bowel movements per day on standard anti-diarrheal regimen (which includes somatostatin analogs and/or Telotristat Ethyl). Additionally, a plasma 5-HIAA, or a urine 24-hour 5-HIAA or plasma secretory hormone levels (VIP, gastrin) above the upper limit of normal per reference lab. Patients may be grouped into this cohort based on a previous plasma 5-HIAA level though the final cohort determination will be made based upon the 5-HIAA level drawn during screening. Non-Carcinoid Syndrome: Participants who have histopathologically confirmed neuroendocrine tumor and have 4 or more bowel movements per day on standard anti-diarrheal regimen (which may or may not include somatostatin analogs), but do not have elevated results for one of the following: plasma 5-HIAA, or 24-hour urine 5-HIAA or other plasma secretory hormone levels (VIP, gastrin) above the upper limit of normal per reference lab. Patients may be grouped into this cohort based on a previous plasma 5-HIAA level though the final cohort determination will be made based upon the 5-HIAA level drawn during screening * ECOG performance status ≤ 2 (Karnofsky ≥60%) * Ability to tolerate thin liquids by mouth at the time of enrollment. * Ability to understand and the willingness to sign a written informed consent document. * Subject who are willing to take enterade® as instructed will be eligible.
