Brief summary

This study is a randomized, double-blind, placebo-controlled Phase 1 Clinical Trial of 24 healthy individuals to test the safety, tolerability and pharmacokinetics of a single subcutaneous administration of Serpin Peptide 16 (SP16), a Serine Protease Inhibitor (Serpin)-like, small peptide agonist of the Low Density Lipoprotein Receptor-like Protein 1 (LRPP1) hypothesized to have anti-inflammatory activity.

Detailed description

One of the major determinants for outcome in patients with acute myocardial infarction (AMI) is the degree of inflammatory response. SP16 is a synthetic anti-inflammatory peptide developed to reproduce the anti-inflammatory activities of naturally occurring Serpins and has been tested as a treatment for AMI in mice. This Phase I trial will be the first to test the hypothesis that a single subcutaneous administration of SP16 is safe and well tolerated in healthy individuals, while also assessing the pharmacokinetic parameters of three different dosages. Participants will undergo direct clinical monitoring for up to 12 hours after drug administration. Additionally, participants will follow up with the same assessments at 24 hours, 48-72 hours and 7 days post drug administration.

Intervention model description

This study is set up as 3 sequential parallel studies, each testing a different drug dosage against placebo. In each dosing cohort, three patients (2 active and 1 placebo) will be randomized to receive a single study drug infusion on separate days, at least 24 hours apart. The remaining subjects in each dosing cohort (1 placebo and 4 active) will receive study drug after at least 24 hours from the 3rd subject.
