Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The pain associated with vaso-occlusive crisis (pain crisis) in sickle cell disease is caused in part by lack of oxygen and increased tissue acid because blood flow is blocked by stiff sickle red cells. Administration of sodium nitrite should generate nitric oxide in this area of hypoxia and acidosis and improve blood flow.

Sodium nitrite injection, USP
Administration if sodium nitrite injection, USP
sodium nitrite injection, usp
Sodium nitrite injection, USP will be administered in blocks of six subjects (3 sodium nitrite and 3 no drug). A total of five dose levels are planned, pending safety starting. Drug will be given by continuous infusion infusion for 48 hours starting at 6 nmol/min/kg (10% of the maximal tolerated dose).

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
1. Male or female subject aged between 8 and 23 years of age; only patients up to the age of 23 will be studied at Childrens Hospital Los Angeles
2. Electrophoretic diagnosis of sickle cell disease;
3. Sudden onset of acute pain involving \>=1 sites typical of vaso-occlusive crisis (Vaso-occlusive crisis is defined as acute, severe pain in the extremities, chest, abdomen, or back that can not be explained by other complications of sickle cell disease or by a cause other than sickle cell disease.);
4. Severe pain requiring parenteral analgesics and hospitalization.
5. Informed consent obtained from a legal representative or from subjects 18 years of age or older before enrollment;
6. Being willing and able to be followed for at least 30 days for evaluation.
Exclusion Criteria
1. Clinically significant bleeding;
2. Current drug abuse or participation in methadone program;
3. Episode of pain requiring hospitalization within 2 weeks prior to current admission;
4. Other complications of sickle cell disease including cerebrovascular accident, pulmonary hypertension, or seizure;
5. Pregnancy (confirmed by a serum human chorionic gonadotropin pregnancy test) or breast feeding;
6. Blood pressure less than 25th percentile for the subject's age and sex on admission or at the time of screening;
7. Methemoglobinemia \>3%;
8. Anemia with hemoglobin level less than 6 g/dL;
9. Red blood cell G6PD deficiency, by laboratory testing prior to enrollment;
10. History of allergy to nitrites or allergy to other substances characterized by dyspnea and cyanosis;
11. Treatment with allopurinol, a medication that could interfere with nitrite metabolism, within the past 30 days before screening;
12. Treatment with any investigational drug within the past 30 days;
13. Significant acute or chronic concomitant diseases (including renal, hepatic, cardiovascular, pulmonary, or oncologic disease, sepsis, pulmonary edema, pulmonary embolism) that would be inconsistent with survival for at least 6 months;
14. Any subject judged by the clinical investigator or study manager to be inappropriate for the study.
