Summary

The goal of this phase IIc clinical trial is to learn if recombinant human thymosin beta 4 injection (NL005) works to treat heart damage in people who have had a serious type of heart attack called ST-segment elevation myocardial infarction (STEMI) and have been treated with emergency percutaneous coronary intervention (PCI, a procedure to open the blocked artery). It will also learn about the safety of NL005. The main questions it aims to answer are:

* Does NL005 lower the size of permanent heart muscle damage measured by cardiac magnetic resonance (CMR) scan 90 days after treatment?
* What medical problems do participants have when taking NL005?

Researchers will compare two different doses of NL005 to a placebo (a look-alike substance that contains no drug) to see if NL005 works better to reduce heart damage caused by the heart attack.

Participants will:

* Receive NL005 or placebo through a vein within 4 hours after the PCI procedure, then once a day for 7 days
* Stay in the hospital for the first week for monitoring, blood draws, and electrocardiograms (heart tracings)
* Have a CMR scan on Day 6 and Day 90 to measure the size of the heart injury
* Return to the hospital for checkups on Day 30 and Day 90
* Be contacted by the study team (by phone or online) 3 times during the first year and come back to the hospital on Day 360 to check long-term recovery

Conditions

  • Acute Myocardial Infarction (AMI)
  • Acute Myocardial Infarction of Anterior Wall
  • Acute Myocardial Infarction With ST Elevation
  • Acute Myocardial Infarction of Left Ventricle
  • Acute Myocardial Infarction With ST Segment Elevation

Interventions

DRUG

Recombinant Human Thymosin Beta 4 Injection (NL005)

NL005 is a sterile solution of recombinant human thymosin beta 4 formulated for intravenous injection. It is supplied as a 1.5 mg (1 mL) vial and stored at 2-8°C. For each dose, the appropriate volume is drawn to achieve 10 µg/kg or 20 µg/kg, and the total volume is adjusted to 5 mL with compatible diluent before administration.

DRUG

Placebo

The placebo is a sterile solution identical in appearance to NL005 and contains no active ingredient. It is supplied as a 1 mL vial and stored at 2-8°C. Each dose is formulated in a total volume of 5 mL and administered intravenously.
