This is a phase III, prospective, multicenter, open-label, crossover study of the safety and efficacy of NH002-enhanced echocardiography in adult subjects with suboptimal images on non-contrast 2D transthoracic echocardiography with harmonic imaging within 30 days ahead of NH002 administration. The efficacy for two different modes of administration (i.e., IV bolus injection and infusion) will be evaluated independently.
Inclusion Criteria:
Exclusion Criteria:
Any evidence of other severe or unstable cardiopulmonary and/or systemic hemodynamic conditions deemed unsuitable for the study by the investigator(s) prior to NH002 dose administration, including, but not limited to:
Known or suspected hypersensitivity to one or more of the ingredients of NH002, perflutren, Definity, or other echocardiographic contrast agents
Known or suspected hypersensitivity to PEG, prior reactions to common PEG-containing products such as colonoscopy bowel preparations, and certain laxatives (e.g., Miralax)
Received an investigational compound within 30 days before enrolling in the study
Received any contrast agent either intravascularly or orally within 48 hours prior to NH002 dose administration
Pregnant or lactating female. Exclude the possibility of pregnancy:
Serious medical or psychiatric illness/condition likely, in the judgment of the investigator, to interfere with compliance with protocol treatment/research
Subjects who are enrolled in the study will undergo two-time resting unenhanced ultrasound examination (shortly before each dose of NH002 administration) and two-time NH002 contrast-enhanced examination on the same day at Day 1 (with the first administration via bolus injection and the second via infusion), with the standard apical 4-, 2-, and 3-chamber views obtained with B-mode and contrast-specific imaging, respectively.
