Trial of Acebilustat for the Treatment of Upper Arm Lymphedema

This study is designed to investigate the response of unilateral upper extremity (arm) lymphedema, during pharmacologic treatment of lymphedema with oral placebo and oral acebilustat. Participants will receive "study drug" (Acebilustat or placebo), for 9 months. For 3 of these months, the participant will receive placebo; for 6 of these months, the participant will receive active ingredient, acebilustat. The study is blinded which means that the participant will not be told which study pill they are taking.

Stanford is currently accepting patients for this trial.
