First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested a daily pill called acebilustat in 40 adults with long-term arm lymphedema (stage 2, lasting over 6 months). Participants took either the drug or a placebo for 9 months, with the first 3 months on placebo for all. The main goal was to see if the drug reduces skin thickness in the affected arm. Researchers also measured changes in arm volume and structure using ultrasound.
