Brief Summary:
The purpose of this study is to determine whether a single intracoronary infusion of an adenovirus serotype 5 virus expressing the gene for human fibroblast growth factor-4 (Ad5FGF-4) is effective in improving angina-limited exercise duration, angina functional class, frequency of angina attacks, frequency of nitroglycerin usage, and quality of life. Half of the study participants will receive Ad5FGF-4, and half will receive placebo. The primary endpoint is the change from baseline to Month 6 in Exercise Tolerance Test (ETT) duration. Long-term safety of Ad5FGF-4 will also be assessed.

Primary Outcome Measures :
  1. Change in Exercise Tolerance Test (ETT) duration [ Time Frame: Baseline and Month 6 ]

  2. Change in weekly angina frequency [ Time Frame: Baseline and Month 6 ]
    Average weekly angina episodes

  3. Change in weekly nitroglycerin usage [ Time Frame: Baseline and Month 6 ]
    Average weekly nitroglycerin usage

  4. Change in quality of life [ Time Frame: Baseline and Months 6 and 12 ]
    Seattle Angina Questionnaire

  5. Safety of Ad5FGF-4 [ Time Frame: Through Month 6 ]
    Adverse events and clinical laboratory testing

  6. Long-term safety of Ad5FGF-4 [ Time Frame: Through Month 60 ]
    Occurrence of clinically significant events

Ages Eligible for Study:   55 Years to 75 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Patients 55-75 years of age inclusive
  • Refractory angina CCS Class III or IV
  • At least 5 angina episodes per week on average
  • Diagnostic coronary angiogram in the past 12 months confirming the presence of coronary artery disease in patients who are not candidates for standard interventions [percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG)]
  • Patients without significant and adequate reduction or relief of angina in spite of treatment with at least two functional classes of chronic anti-angina medication at the maximally tolerated dose. Functional classes of anti-angina medications include β-blockers, calcium channel blockers, nitrates, and metabolic modulators (i.e. ranolazine). Participants must have been on a stable anti-angina medication regimen for at least 4 weeks before signing the informed consent form.
  • Documented clinical evidence of inducible ischemia on stress testing within the past 6 months [e.g. nuclear perfusion imaging (stress SPECT or PET), stress ECHO, stress MRI, stress ETT (≥1 mm ST Segment depression)].
  • Exercise duration of 3-7 minutes on ETT (Modified Bruce Protocol), limited by angina grade 3 (patient feels chest pain that has increased to the point that he/she would stop activity and take nitroglycerin)
  • Patient develops ≥1mm ST segment depression on each of the qualifying baseline ETT
  • Left ventricular ejection fraction (LVEF) of ≥30%
  • Postmenopausal female patients, women of childbearing potential and men willing to use an effective contraception method while in the study and/or who agree not to become pregnant or make their partner pregnant throughout the study and during one year after administration of the study drug
  • Female subjects of childbearing potential who have a negative urine pregnancy test, and are willing to use an acceptable form of birth control during the study. For the purpose of this study, a female of childbearing potential is a female who is not postmenopausal for greater than 2 years, has not had a tubal ligation, and has not had a hysterectomy. For the purpose of this study, the following are considered acceptable methods of birth control:

    • Oral contraceptives, contraceptive patches/implants
    • Intrauterine device (IUD) together with condom or spermicide for at least three months
    • Condom and spermicide
    • Abstinence with a documented second acceptable method of birth control should the subject become sexually active
