Actual (reported)OBJECTIVES: I. Compare the efficacy of local care alone vs local care plus arginine butyrate in terms of healing rate in patients with refractory sickle cell ulcers. II. Determine the effect of arginine butyrate therapy on tissue factors related to promotion or inhibition of wound healing in these patients. III. Determine whether the regimen used in this study is appropriate for testing in pivotal trials.

Actual (reported)Healing Defined as a Decrease in Ulcer Area by at Least 25% of the Initial Area
Treatment Arm: The AB is given as an IV infusion at 500 mg/kg over 6-9 hrs. 5 days per week for 12 weeks. After 12 weeks of therapy, if he ulcer has decreased by 25% , the AB may be continued for additional 8 weeks (twice) or, until ulcer closes plus 2 weeks, additionally. Ulcers photographed, traced, and ulcer areas calculated by computerized planimetry.
participants were followed for an average of 3 months
% Ulcers Which Completely Healed in Each Group, After 3 Months
two additional courses of 8 week cycles
Each subject provided his/her own dressing e.g,standard local care includes cleaning, saline irrigation, dressing changes only for 8 weeks twice a week.
Arginine Butyrate IV plus Standard local care dressing for a total of 12 weeks. Low dose 500 mg/kg or, increased dose 750 mg/kg. First week AB given 5 days in a row, over 6 to 12hours.
To determine if Arginine Butyrate accelerates healing of refractory leg ulcers over Standard Local Care alone.
To heal leg ulcers.

Cannabinoids for the Reduction of Inflammation and Sickle Cell Related Pain
Patients are randomly assigned (following a table of random numbers prepared by a blinded statistician) between two arms of the study. Arm I is Standard local care dressing only, and Arm II is standard local care plus Arginine Butyrate (AB), the Investigational New Drug. Ulcers observed \& traced weekly. Ulcer area calculated by computerized planimetry. After 12 weeks of therapy, if the ulcer size decreased by at least 25%, the AB may be continued for another 8 weeks (twice), or until the ulcer closes, plus an additional 2 weeks. The patients randomized to the Control Arm (standard local care) were given the option of crossing over to Arm II If, ulcers did not close after 8 weeks of standard local care.
