Summary

Standard of care for Lymphatic Malformations has been surgical excision. We have been using OK432/Picibanil (generously supplied by Chugai Pharmaceuticals in Japan) since 1992 with great success for macrocystic disease. The objective of the study was to provide OK-432 immunotherapy to subjects with macrocystic or mixed (> 50% macrocystic) lymphatic malformations (LMs) and investigate the efficacy and safety of OK 432 as a treatment option in subjects with LMs.
