Effect of DLBS1033 After Primary PCI in Patients With STE-ACS
Study Details
Study Description
Brief Summary
This is a prospective, randomized, double-blind, double-dummy, and controlled clinical study over a total of 4-week therapy with DLBS1033 in the management of STE-ACS after a primary PCI. There will be 40 STE-ACS subjects (20 subjects in each group) planned to complete the study.

Phase 2/Phase 3 |
Detailed Description
STE-ACS patients who undergo intermediate-delayed (> 3 hours after the onset of the STEMI) primary PCI will be enrolled in the study. Before the intervention, they will be given standard medication for PCI.
Right after PCI, all eligible subjects will be assessed for microvascular perfusion, using a pressure-temperature sensor-tipped coronary guidewire.
The day after, in addition to the dual antiplatelet therapy, i.e. 80 mg aspirin once daily and clopidogrel 75 mg once daily, DLBS1033 at a dose of 980 mg three times daily or its placebo will be given to the subjects for 4 weeks.
Clinical and laboratory examinations to evaluate the investigational drug's efficacy and safety will be performed at Baseline (right after subjects undergo the primary PCI) and at the End of study (week 4th of DLBS1033 therapy).

Outcome Measures
Primary Outcome Measures
- Index of microvascular resistance (IMR) [Week 4]
Improvement in the index of microvascular resistance (IMR) from baseline to week 4th of treatment, measured using the pressure and temperature sensor-tipped guidewire.
Secondary Outcome Measures
- Improvement in fractional flow reserve (FFR) from baseline to week 4th of treatment, measured using the pressure and temperature sensor-tipped guidewire [Week 4]
Improvement in fractional flow reserve (FFR) from baseline and to Week 4th of treatment, measured using the pressure and temperature sensor-tipped guidewire.
- LV function [Week 4]
Improvement in several parameters of left ventricular (LV) function [EF, ESV, EDV], from baseline and to Week 4th of treatment will be measured by 2D echocardiography.
- Routine hematology [Week 0 and 4]
Routine hematology, including: RBC, WBC, and platelet count, will be measured at baseline and week 4th of treatment.
- Routine hematology (Hemoglobin) [Week 0, 2 and 4]
Hemoglobin will be measured at baseline and every interval of 2 weeks over the 4 weeks of treatment.
- Routine hematology (Hematocrit) [Week 0, 2 and 4]
Hematocrit will be measured at baseline and every interval of 2 weeks over the 4 weeks of treatment.
- Liver function [Week 0 and 4]
Liver function measured includes: serum ALT (SGPT), serum AST (SGOT), alkaline phosphatase, and total bilirubin.
- Renal function [Week 0 and 4]
Renal function measured includes: serum creatinine and BUN.
- Haemostasis parameter (Prothrombin time (PT)) [Week 0, 2, and 4]
Prothrombin time (PT) will be measured at baseline and every interval of 2 weeks over the 4 weeks of study treatment.
- Haemostasis parameter (International Normalized Ratio (INR)) [Week 0, 2, and 4]
International Normalized Ratio (INR) will be measured at baseline and every interval of 2 weeks over the 4 weeks of study treatment.
- Adverse event [Week 0 - 4]
Adverse events (especially major and minor bleeding) are observed and carefully evaluated along the course of the study.
Eligibility Criteria
Criteria
KEY Inclusion Criteria:
