NP202 for Treatment of Post -STEMI Left Ventricular Systolic Dysfunction

Phase 2
Conditions
ST Elevation Myocardial Infarction
Interventions
Other: Placebo
Registration Number
NCT02557217
Lead Sponsor
Armaron Bio Pty Ltd
Brief Summary

NP202 is an experimental drug being developed by Armaron Bio Pty Ltd for potential use as a treatment for people after they have had a heart attack (MI).

Detailed Description

After someone has a MI, their heart 'remodels', which means that it changes in size and shape. This damage can lead to it being weaker and less efficient, and ultimately to major heart problems. There are some drugs currently available which help prevent remodelling and are used for treatment post-MI. However, there is still a high rate of remodelling and major heart problems in people post-MI. NP202 works in a different way to the drugs that are currently approved, and has been shown in animal studies to prevent post-MI remodelling.

This study will assess NP202 versus placebo on remodelling over a 3 month treatment period, with 1 month follow up

Inclusion Criteria
  • Have had a confirmed ST elevation myocardial infarction (STEMI) in the previous 5 days, which met all of the following criteria;
