NCT03692234

Brief Summary

This study represents a follow-up of the previous study "Single and Multiple Doses of an Oral Formulation of L-Homoarginine in Healthy Human Subjects" (NCT02675660). This study will evaluate the applicability of an oral formulation of L-homoarginine to normalize homoarginine blood levels in patients with acute ischemic stroke.
