Study summary

The purpose of this study is to evaluate the safety, efficacy, and pharmacokinetics (PK) of three dose levels of FDY-5301 compared to placebo in STEMI patients undergoing PCI.

Read the detailed description

The purpose of this study is to evaluate the safety and effectiveness of an experimental drug called FDY-5301 as a possible treatment to reduce the size of the injury to the heart caused by the heart attack. An experimental drug is one that is being tested and is not approved by the United States Food and Drug Administration (FDA).

A heart attack occurs when a heart (coronary) artery supplying blood to the heart muscle becomes blocked and the heart muscle is injured. You will be having a cardiac catheterization procedure to clear the blockage in your coronary artery that caused your heart attack. This procedure works well but may not completely prevent some injury to the heart muscle which occurs when the blood supply is initially restored to the heart. This is known as "reperfusion injury".

FDY-5301 is a single intravenous injection. About 80 subjects are expected to participate in this study at about 20 research sites in the United States and Europe. Each subject's participation is expected to last about 6 months after receiving the study drug.

Subjects who meet all inclusion criteria will be randomly assigned to one of 4 study groups. Three groups will receive FDY-5301 (low, intermediate, or high dose) and 1 group will receive a placebo.The study drug (FDY-5301 or placebo) will be given through a vein (intravenously) during the catheterization procedure. This is a double-blind study so neither the patient nor study personnel will know whether the dose is active drug or placebo until the end of the study.

Inclusion criteria

  1. 18-80 year old male subjects
  2. 18 to 80 year old female subjects who are not of .
  3. Accepted for Primary PCI with diagnosis of first STEMI, based on clinical and criteria (ST-elevation at the J-point in two contiguous leads with the cut-off points: ≥0.2 millivolt (mV) in men or ≥0.15 mV in women in leads V2-V3 and/or ≥0.1 mV in other leads), within 12 hours of symptom onset.

Written prior to study participation (either by the subject or a legally authorized representative of the subject)

Exclusion criteria

Exclusion Criteria:

  1. Previous myocardial infarction
  2. Left bundle branch block (LBBB)
  3. Previous coronary artery bypass graft surgery (CABG)
  4. Major hemodynamic instability or uncontrolled ventricular arrhythmias
  5. Known to CMR
  6. Patients with known thyroid disease
  7. Subjects with past or current renal impairment requiring dialysis
  8. Pregnant or females of child bearing potential
  9. Body weight > 120 kg or (BMI) > 35 kg/m2
  10. Use of drugs or devices within 30 days prior to enrollment into the study.
  11. of less than 1 year due to non-cardiac pathology
  12. Any abnormality identified at the time of screening that in the judgment of the Investigator or any sub-Investigator would preclude safe completion of the study
Terms in these criteria, in plain language(8)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

ECG (electrocardiogram)

A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
