A Phase 1C, Open Label, Single Ascending Dose Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of DM199 Administered Intravenously with a Polyvinyl Chloride Bag in Adult Healthy Subjects and Adults Recently Taking Angiotensin-Converting Enzyme Inhibitors.

ABSTRACT: This small phase 1C, open-label, single ascending dose study evaluated the safety, tolerability, and pharmacokinetics (PKs) of DM199, a recombinant form of human tissue kallikrein-1 (KLK1). A small sample size of both healthy subjects and hypertensive adults recently taking angiotensin-converting enzyme inhibitors was studied. KLK1 has a known role in vasodilation and blood flow regulation, with potential implications for treatment of acute ischemic stroke (AIS) by focally enhancing cerebral perfusion. A total of 12 subjects were enrolled; 9 healthy subjects received escalating doses of DM199 (0.1-0.5 µg/kg), while 3 hypertensive subjects received the maximum tolerated dose of 0.5 µg/kg. Safety assessments indicated that DM199 was well tolerated, with mild adverse events reported, such as
