What is an Investigator-Initiated Study?

An IIS is a study in which the investigator or research institution is the study Sponsor. As the Sponsor, the Investigator is responsible for the initiation, design, implementation, and regulatory compliance of a research protocol. Lexicon may support an IIS in the form of drug product and/or financial support.

Currently, the IIS program is focused on research related to Xermelo® (telotristat ethyl), Lexicon’s first FDA-approved oral therapy for the treatment of carcinoid syndrome diarrhea. We prioritize clinical vs pre-clinical proposals.

IIS Areas of priority include but not limited to the following:

  1. Carcinoid Syndrome Diarrhea
  2. Carcinoid Syndrome
  3. Anti-tumor activity in Neuroendocrine Tumors (NETs)
  4. Anti-tumor activity in Biliary Tract Carcinoma (BTC)
