About this trial

This is an interventional treatment trial for Sickle Cell Disease focused on measuring Arginine Therapy

Eligibility Criteria

3 Years - 21 Years (Child, Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Established diagnosis of sickle cell disease (SCD); all genotypes
  • Pain requiring medical care in an acute care setting (such as the emergency department or ED, hospital ward, day hospital, clinic) not attributable to non-sickle cell causes, that is moderate-to-severe requiring parenteral opioids

  • Allergy to arginine
  • Two (2) or more ED visits for VOE within the last 7 days prior to CURRENT ED visit
  • Hospitalization within 14 days
  • Previous randomization in this arginine RCT (patient consented and screen failed before receiving study drug or placebo remains eligible for future participation).
  • Use of inhaled nitric oxide, sildenafil or arginine within the last month

Arm Description

Participants will be randomized to receive an intravenous (IV) infusion of L-arginine (100 mg/kg) three times a day until time of discharge from the emergency department (ED) or hospital.

Participants will be randomized to receive an intravenous (IV) infusion of one-time loading dose of L-arginine (200 mg/kg) followed by standard dose (100 mg/kg) three times a day until time of discharge from the emergency department (ED) or hospital.

Participants will be randomized to receive an intravenous (IV) infusion of placebo (normal saline 1-2 ml/kg) three times a day until time of discharge from the emergency department (ED) or hospital.

Outcomes

Primary Outcome Measures

Total Parenteral Opioid Use in IV Morphine Equivalents
The total amount of parenteral opioids used by participants measured in mg/kg of IV morphine equivalents. The total is calculated after study drug delivery for participants in the emergency department (ED) and during hospital stay.

Secondary Outcome Measures

Length of Hospital Stay
The total number of hours spent in the hospital from study drug delivery to time of discharge.
Time to Vaso-occlusive Pain Event (VOE) Resolution in Emergency Department
The total number of hours between study drug delivery and the last parenteral opioid.
Time to Vaso-occlusive Pain Event (VOE) Resolution in Hospital
The total number of hours between study drug delivery and time of last parenteral opioid use, pain relief improved to tolerate oral pain medications
Change in Vaso-occlusive Pain (VOE) Scores
Pain associated with VOE will be measured on a scale of 0-10, by asking subjects to rate their pain level on a subjective scale from 0 to 10, with the ends representing the extreme limits of "no-pain" (0) and "worst pain" (10).
Length of Emergency Department (ED) Stay
Total hours from time of ED triage to ED discharge or hospital admission.
Rate of Emergency Department (ED) Discharge
Number of participants discharged from ED without a hospital ward admission.
Total Opioid Dose (ORAL + Parenteral) in mg/kg IV Morphine Equivalents
Total opioid dose (ORAL + Parenteral) in mg/kg IV morphine equivalents after study drug delivery up to hospital discharge (up to 8 days)
Total Number of Study Drug Doses
The total number of study drug doses given throughout the study period.
Rate of Acute Chest Syndrome
Number of participants who develop acute chest syndrome (not diagnosed prior to study drug delivery) throughout the study period.
Rate of Blood Transfusion
Number of participants requiring a blood transfusion throughout the study period.
Oxygen Saturation Level
Average oxygen saturation level of participants at time of ED arrival
Oxygen Saturation Level
The difference in oxygen saturation levels from emergency department arrival to hospital discharge.
Rate of Return Visits to Emergency Department (ED) Within 72 Hours
Number of ED visits from patients who have been discharged within the previous 72 hours.
Rate of Hospital Re-admissions Within 72 Hours
Number of patients readmitted to the hospital within 72 hours of discharge.
Rate of Return Visits to Emergency Department (ED) Within 30 Days
Number of ED visits from patients who have been discharged within the previous 30 days.
Rate of Hospital Re-admissions With 30 Days
Number of patients readmitted to the hospital within 30 days of discharge.

5. Study Description

Brief Summary
The aim of this study is to determine whether giving extra arginine, a simple amino acid, to patients with sickle cell disease seeking treatment for a pain crisis (vaso-occlusive painful events (VOE) will decrease pain scores, decrease the need for pain medications or decrease length of hospital stay or emergency department visit. Funding Source - FDA OOPD.
Detailed Description
The purpose of this study is to determine the effects of IV L-arginine hydrochloride therapy in children with sickle cell disease (SCD) and vaso-occlusive pain events (VOE). Specifically, the impact on total opioid use (mg/kg) over the duration of their emergency department (ED) visit and hospital stay will be evaluated.
