About this study
Patients with acute myocardial infarction undergoing primary angioplasty are at high risk for renal injury due to the toxic effect of contrast agents. Patients developing renal dysfunction after primary angioplasty have worse outcome. To investigate the role of the antioxidant N-acetylcysteine (NAC) in preventing renal injury in angioplasty, we randomized 352 consecutive patients undergoing primary angioplasty into three groups: the first group received NAC at standard dose (NAC group, 600 mg i.v. bolus before primary angioplasty, followed by oral 600 mg twice daily for the following 48 hours; n=115), the second group received NAC at double dose (DD-NAC group; 1,200 mg i.v. bolus and oral 1,200 mg twice daily for 48 hours; n=118), and the last group received placebo (controls; n=119).

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing intravenous and oral N-acetylcysteine in people with Contrast-Induced Nephropathy and Acute Myocardial Infarction, run by University of Milan at 1 site in Italy.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 18 Jul 2006. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence of contrast-induced nephropathy. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00237614, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Jul 2006; AzTrials last refreshed its copy on 8 Nov 2026.
