- Original description
The primary purpose of this study is to evaluate whether the drug EI-001 can help improve vitiligo symptoms. EI-001 is a novel antibody drug that affects the immune system to decrease uncontrolled inflammation. EI-001 has been investigated in human cell cultures, animal studies, and in a Phase 1 healthy volunteer study. The results so far show that EI-001 is a tolerable and potential new treatment for immune diseases such as vitiligo.Read full original descriptionShow less
