NCT03427619

Brief 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.

Outcome Measures

Primary Outcomes (1)

  • Number of Participants With Clinical Success at 1 to 6 Months Post-Therapy as Assessed by Imaging

    Clinical success was defined as having either a complete (90% 100%) or substantial (60% 89%) reduction in lymphatic malformation (LM) volume after treatment. Response was determined using post treatment imaging studies at approximately 1 to 6 months after completion of treatment

    1 to 6 Months Post-Therapy

Secondary Outcomes (3)

  • Number of Participants With Clinical Response 1 to 6 Months Post-Therapy as Assessed by Imaging

    1 to 6 Months Post-Therapy

  • Number of Participants With Investigator-Evaluated Overall Response

    1 to 6 Months Post-Therapy

  • Change From Baseline in Lesion Volume

    Baseline and 1 to 6 Months Post-Therapy

Limitations and Caveats

Results are based on a retrospective analysis of source-verified data that include subjects enrolled in the open label study. This study was conducted to provide patients with continued access to OK-432 on a compassionate use basis. Response data were not well documented for everyone. Subjects with missing data included those who were lost to follow up, had incomplete or missing CRFs or imaging studies.
