Study of Choline Chloride for Injection in Adolescent and Adult Patients With Intestinal Failure Receiving Long Term Parenteral Support

Summary

TARA-001-301 is a Phase 2b/3 randomized Open-Label Dose-Selection study with an Open-Label Extension and randomized Double-Blind, Placebo-Controlled Study with Open-Label Extension to investigate the safety and efficacy of Choline Chloride for Injection (Low Dose and High Dose) versus Placebo in adolescents (ages 12 to \< 18 years of age) and adults (≥ 18 years of age) with intestinal failure receiving long-term PS when oral or enteral nutrition is not possible, insufficient, or contraindicated. Participants will be enrolled in one of 2 parts, each part will be followed by an open-label extension period of approximately a year. Part 1: Open-Label Dose-Selection Phase Part 2: Double-Blind, Placebo-Controlled Phase The purpose of the Open-Label Dose-Selection Phase is to evaluate the safety, tolerability, how Choline Chloride for Injection (study drug) is distributed in the body, and to select 2 of 3 doses for testing in the Double-Blind, Placebo-Controlled Phase. The purpose of the Double-Blind, Placebo-Controlled Phase is to assess the safety of the study drug and how well the study drug works at the 2 selected dose levels.
