A Phase III Safety and Efficacy Study of L-Glutamine to Treat Sickle Cell Disease or Sickle βo-thalassemia

Sickle Cell Anemia Clinical Trial

Official title: A PHASE III, PROSPECTIVE, RANDOMIZED, DOUBLE-BLIND, PLACEBO-CONTROLLED, PARALLEL-GROUP, MULTICENTER STUDY OF L GLUTAMINE THERAPY FOR SICKLE CELL ANEMIA AND SICKLE ß0-THALASSEMIA

Status Completed

Clinical Trial Summary

The purpose of this research is to evaluate the effects of L-glutamine as a therapy for Sickle Cell Anemia or Sickle ß0 Thalassemia as evaluated by the number of occurrences of sickle cell crises.

Clinical Trial Description

Primary objective:

To evaluate the efficacy of oral L-glutamine as a therapy for sickle cell anemia and sickle ß0-thalassemia as evaluated by the number of occurrences of sickle cell crises.

Secondary objectives:

To assess the effect of oral L-glutamine on: (a) frequency of hospitalizations for sickle cell pain; (b) frequency of emergency room/medical facility visits for sickle cell pain; and (c) hematological parameters (hemoglobin, hematocrit, and reticulocyte count); and to assess the safety of L-glutamine as a therapy for sickle cell anemia as evaluated by adverse events, laboratory parameters, and vital signs.

Methodology:

This was a 2:1 randomized, double-blind, placebo-controlled, parallel-group, multicenter study in patients with sickle cell anemia and sickle ß0-thalassemia who were at least 5 years old. Informed consent was obtained up to four weeks prior to Week 0 (Baseline). Screening procedures were performed anytime between the date of consent and Week 0, as long as all eligibility criteria had been confirmed prior to Week 0. At Week 0, patients were randomized (to L-glutamine or placebo) and underwent 48 weeks of treatment (orally BID), with dose calculated according to patient weight. Patient clinic visits occurred every 4 weeks, and phone calls took place between visits to monitor compliance. After 48 weeks of treatment, the dose was tapered to 0 within 3 weeks. A final evaluation visit occurred 2 weeks after last dose for a total of 53 weeks on study. ;
