Important Safety Information and Indication

  • Contraindications: XERMELO is contraindicated in patients with a history of a hypersensitivity reaction to telotristat. Reactions have included angioedema, rash and pruritis.
  • Warnings and Precautions: XERMELO may cause constipation, which can be serious. Serious complications of constipation have been reported during clinical trials and post marketing with individual reports of intestinal perforation, obstruction, and fecaloma. Monitor for signs and symptoms of constipation and/or severe, persistent, or worsening abdominal pain in patients taking XERMELO. Discontinue XERMELO if severe constipation or severe, persistent, or worsening abdominal pain develops.

  • Warnings and Precautions: XERMELO may cause constipation, which can be serious. Serious complications of constipation have been reported during clinical trials and post marketing with individual reports of intestinal perforation, obstruction, and fecaloma. Monitor for signs and symptoms of constipation and/or severe, persistent, or worsening abdominal pain in patients taking XERMELO. Discontinue XERMELO if severe constipation or severe, persistent, or worsening abdominal pain develops.
  • Adverse Reactions: In a clinical trial of patients with carcinoid syndrome diarrhea and 4-12 bowel movements per day, the most common adverse reactions (≥5%) include nausea, headache, increased gamma-glutamyl transferase, depression, flatulence, decreased appetite, peripheral edema, and pyrexia. In a second clinical trial of patients with carcinoid syndrome diarrhea and less than 4 bowel movements per day, additional adverse reactions of abdominal pain and constipation were reported in ≥5% of patients.
  • Drug Interactions: If necessary, consider increasing the dose of concomitant CYP3A4 and CYP2B6 substrates, as XERMELO may decrease their systemic exposure. If combination treatment with XERMELO and short-acting octreotide is needed, administer short-acting octreotide at least 30 minutes after administering XERMELO.
  • Use in Special Populations: XERMELO is not recommended in patients with moderate and severe hepatic impairment.

Indication

XERMELO is a tryptophan hydroxylase inhibitor indicated for the treatment of carcinoid syndrome diarrhea in combination with somatostatin analog (SSA) therapy in adults inadequately controlled by SSA therapy.
