Criteria
Inclusion Criteria:

- For Cohort A, men and non-pregnant/non-lactating women in good health who are 18 to 70
years of age and who have a low chance of CAD will be enrolled.

- For Cohort B, men and non-pregnant/non-lactating women in good health who are 18-70
years of age who have had a prior MI and/or coronary artery revascularization
intervention >90 days before AI-700 administration, without new or recurrent angina
will be enrolled.

Exclusion Criteria:

- Healthy volunteers in Cohort A who have or have had any of the following conditions
will be excluded from the study: clinically significant intra-cardiac shunts or any
other cardiovascular structural and/or severe functional abnormalities on the
Qualification Echo, unless deemed not clinically relevant by the Investigator and
subsequently approved by the Sponsor; ejection fraction (EF, estimated from the
Qualification Echo) that is ≤55% (outside normal range), history or clinical
manifestations of significant mental illness or significant pulmonary, hematological,
renal, hepatic, central nervous, cardiovascular, genitourinary, or gastrointestinal
disorders, or diabetes; history of any major surgical procedure within 90 days of
Screening/Baseline; body mass index (BMI) >35; sitting systolic blood pressure <90
mmHg or >150 mmHg, diastolic blood pressure <50 mmHg or >95 mmHg, or a pulse rate <45
bpm or >90 bpm; oxygen saturation <92% at rest; and inadequate image quality on the
Qualification Echo. Other exclusion criteria include: participation in an
investigational drug/device study within 30 days prior to dosing (90 days for UK
sites), participation in a previous clinical trial of AI-700, non-seasonal asthma
within the past 3 years or recent seasonal asthma requiring prescription medication,
frequent (>5/min) premature ventricular or atrial contractions (PVC, PAC), and any
≥2nd AV block, bundle branch block (BBB), or rhythm abnormality.

- Stable cardiac patients in Cohorts A or B who have had any of the following conditions
will be excluded from the study: any clinically unstable condition or major surgery
within 30 days prior to Screening/Baseline (including but not limited to severe
arterial hypertension, pulmonary hypertension, or any increase in pulmonary pressures
due to increased pulmonary resistance, hypotension, bradycardia, tachycardia, unstable
angina); cerebrovascular accident or transient ischemic attack within 90 days prior to
dosing; congestive heart failure graded as New York Heart Association Class 3 or 4
within 90 days prior to dosing; significant left main CAD (≥50% stenosis); moderate to
severe chronic obstructive pulmonary disease (COPD) within 6 months prior to dosing;
or oxygen saturation <90% at rest; and inadequate image quality on the Qualification
Echo. Candidates with clinically significant intra-cardiac shunts or any other
cardiovascular structural and/or severe functional abnormalities per the Qualification
Echo [including intra cardiac shunts; uncorrected congenital heart disease (i.e.,
severe valvular disease; large amount of pericardial effusion], EF (as estimated from
the Qualification Echo) of <40%; are also not eligible to participate. Subjects who
exhibit new or changing ECG abnormalities at any time between Screening and AI-700
dosing will be similarly excluded. Other exclusion criteria include: participation in
an investigational drug/device study within 30 days prior to dosing (90 days for UK
sites), participation in a previous clinical trial of AI-700, non-seasonal asthma
within the past 3 years or recent seasonal asthma requiring prescription medication,
organ transplant or end-stage organ failure, and active seizure disorder. Candidates
will also be excluded for uncontrolled atrial fibrillation, frequent (>5/min) PVCs or
PACs, history of prolonged QT/QTc (>500 msec), use of automatic implantable
cardioverter/defibrillator, and any ≥2nd AV block, BBB, or rhythm abnormality that has
not been evaluated and treated by a specialist or for which current treatment is not
adequately effective to the extent that subject safety is assured.
