Trial Information

Treatment of Cystic Hygroma (Lymphangiomas) in Children- Picibanil(OK432) Sclerotherapy-Multicenter Trial

PROTOCOL OUTLINE: This is a multicenter study. Patients are stratified according to prior
treatment (no prior treatment vs prior surgical treatment) and geographic area.

Patients who meet all study criteria are put in the "Immediate Treatment Group." Patients
receive an intralesional injection of picibanil (OK432) with the aid of ultrasonography or
transillumination for localization of cysts. Treatment repeats every 6-8 weeks for a total
of up to 4 injections.

After completion of treatment, patients are followed at 6 months, 1 year, and 2 years.
