Myocardial InfarctionPhase 1/2NCT00093197
Safety of KAI-9803 for Injection With Angioplasty Following Heart Attack
A Phase 1/2 study testing KAI-9803 for Injection in people with Myocardial Infarction, run by KAI Pharmaceuticals at 1 site in United States.
Trial summary
Restoring blood flow to coronary arteries as quickly as possible is the best way to reduce the damage to the muscle that occurs with a heart attack. However, up to 25-50% of patients who have angioplasty may have ongoing damage to the heart muscle when the blockage is opened and blood flow is restored. Read more about this study

About this study
Official title: Intracoronary KAI-9803 for Injection as an Adjunct to Primary Percutaneous Coronary Intervention for Acute ST-Elevation Myocardial Infarction
Restoring blood flow to coronary arteries as quickly as possible is the best way to reduce the damage to the muscle that occurs with a heart attack. However, up to 25-50% of patients who have angioplasty may have ongoing damage to the heart muscle when the blockage is opened and blood flow is restored. Complications which may result from this ongoing damage include a larger area of damaged muscle in the heart, enlargement of the heart, an increased risk of death, and an increased risk of heart failure. Some of the ongoing damage may involve increased levels of the protein kinase C (PKC) enzyme. KAI-9803 is a selective inhibitor of delta PKC. In this study, delta PKC is used with angioplasty and other standard procedures to restore blood flow after a heart attack. This study is designed to evaluate safety of different amounts of KAI-9803 when used in treating heart attack patients undergoing angioplasty. We will also try to evaluate whether KAI-9803 can reduce the amount of heart muscle damage and the complications that may occur in these patients.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing KAI-9803 for Injection in people with Myocardial Infarction, run by KAI Pharmaceuticals at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 11 exclusion criteria. 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 2 Sep 2011. 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 United States. 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. Some participants in this study may receive a placebo. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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?
Number of participants with adverse events (time frame: 30 days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 2 Sep 2011; AzTrials last refreshed its copy on 8 Nov 2026.
