A Phase 2 Randomized Double-blind, Placebo-controlled Clinical Trial of Intravenous Citrulline for Vaso-occlusive Pain Episode in Hospitalized Patients With Sickle Cell Disease (CONQUER SCD Pain Trial)
Suvankar Majumdar
Summary
The goal of this clinical trial is to learn if intravenous citrulline works to treat acute pain in hospitalized patients with sickle cell disease. It will also learn about the safety of intravenous citrulline. The main questions it aims to answer are: * Does intravenous citrulline decrease the duration of sickle cell pain during hospitalization * What medical problems do participants have when taking intravenous citrulline? Researchers will compare intravenous citrulline to a placebo (a look-alike substance that contains no drug) to see if intravenous citrulline works to treat acute pain. Participants will: * Receive baseline tests and intravenous citrulline for 16 hours during the hospital stay * After hospital discharge, visit the clinic in about 30 days for checkup and tests
Description
This is a single-center phase 2 randomized double-blind, placebo-controlled trial of intravenous L-citrulline for sickle cell patients ages 4 to 21 years experiencing a vaso-occlusive pain crisis episode (VOE). Eligible subjects will have a documented history of sickle cell disease and inpatient hospitalization for treatment of acute pain with parenteral opioid. Subjects will be randomized to receive high dose intravenous L-citrulline, low dose intravenous L-citrulline or placebo in addition to standard of care. Subjects will be followed closely to evaluate time-to-crisis resolution as the pri…
