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


The purpose of this research is to test the effects of L-glutamine on red blood cells of
patients with Sickle Cell Anemia or Sickle ß0-Thalassemia. Glutamine is a part of protein
and is a part of a person's normal diet. It is often used as a nutritional supplement or as
medication for various medical problems such as intestinal problems. The benefits of
participating in this study may be a decrease in pain and other problems caused by sickle
cell disease.


Inclusion Criteria:

- Patient is at least five years of age.

- Patient has been diagnosed with sickle cell anemia or sickle ß°-thalassemia
(documented by hemoglobin electrophoresis).

- Patient has had at least two documented episodes of sickle cell crises within 12
months of the screening visit.

- If the patient has been treated with an anti-sickling agent within three months of
the screening visit, the therapy must have been continuous for at least three months
with the intent to continue for the duration of the study.

- Patient or the patient's legally authorized representative has given written informed
consent.

- If the patient is a female of child-bearing potential, she agrees to avoid pregnancy
during the study and is willing and agrees to practice a recognized form of birth
control during the course of the study (e.g. barrier, birth control pills,
abstinence).

Exclusion Criteria:

- Patient has a significant medical condition that required hospitalization (other than
sickle cell crisis) within two months of the screening visit.

- Patient has prothrombin time INR > 2.0.

- Patient has serum albumin < 3.0 g/dl.

- Patient has received any blood products within three weeks of the Screening Visit.

- Patient has uncontrolled liver disease or renal insufficiency (refer to Appendix 3
for guidelines).

- Patient is pregnant or lactating or has the intention of becoming pregnant during the
study (if female and of child-bearing potential).

- Patient is currently taking or has been treated with any form of glutamine supplement
within 30 days of the screening visit.

- Patient has been treated with an experimental anti-sickling medication/ treatment
within 30 days of the screening visit (with the exception of hydroxyurea in pediatric
patients).

- Patient is currently taking or has been treated with an investigational drug within
30 days of the screening visit (with the exception of hydroxyurea in pediatric
patients).

- Patient is currently enrolled in an investigational drug or device study and/or has
participated in such a study within 30 days of the screening visit.

- There are factors that would, in the judgment of the investigator, make it difficult
for the patient to comply with the requirements of the study.
