What is Xermelo?
Xermelo tablets are used to treat carcinoid syndrome diarrhea in adults, Xermelo works by blocking the enzyme that helps make serotonin which reduces the amount of serotonin being made to help prevent diarrhea. Xermelo (telotristat ethyl) is a tryptophan hydroxylase inhibitor that specifically targets the underlying cause of carcinoid syndrome diarrhea, which is high serotonin levels. Xermelo is not a chemotherapy.
Carcinoid syndrome diarrhea is caused by carcinoid tumors releasing too much serotonin, which increases wave-like contractions in the gut (peristalsis). These contractions reduce how much water and electrolyte is absorbed from the gut, which leads to diarrhea. Carcinoid syndrome is a rare condition that affects people with metastatic neuroendocrine tumors (mNETs).
Xermelo is used together with medications such as octreotide (Sandostatin), which is a somatostatin analog (SSA) therapy; Xermelo is used with SSA therapy when the SSA therapy has not effectively controlled the diarrhea on its own.
Medications like octreotide work by blocking the release of serotonin. When Xermelo is combined with SSA therapy, they work well together as Xermelo reduces how much serotonin is made, and SSA therapy decreases the amount of serotonin released, leading to an improvement in carcinoid syndrome diarrhea symptoms.
Xermelo received FDA approval on February 28, 2017. Xermelo is indicated for treating carcinoid syndrome diarrhea in combination with somatostatin analog (SSA) therapy, such as octreotide in adults whose carcinoid syndrome diarrhea has not been controlled by SSA therapy.
