Testing Experimental Medication in Healthy Subjects

Study Description

An Ascending Dose Comparison of MVT-100 to Definity in Healthy Volunteers

Definity (perflutren lipid microspheres, Lantheus Medical Imaging) is an ultrasound contrast indicated for use in patients with suboptimal echocardiograms to opacify the left ventricular chamber and to improve the delineation of the left ventricular endocardial border. MVT-100 (the investigational pharmaceutical) is similar to Definity, with the exception of the removal of one lipid in the lipid blend and substitution of another lipid. This study is intended to evaluate the safety and efficacy of MVT-100 using a single ascending dose design in healthy volunteers. Patients are randomized to receive either MVT-100 or Definity and undergo echocardiograms after receiving either MVT-100 or Definity via bolus or IV infusion administration. The primary endpoints evaluated are safety and endocardial border delineation.

Diagnostic Test - Echocardiogram

Images will be recorded in parasternal long, short axis, apical four, two, and three chamber views according to the American Society of Echocardiography (ASE) 17 segment model. Each assessment will include one round of low MI imaging (<0.3) and one round of very low MI imaging (<0.2) in each of the pre-specified windows according to the 2014 ASE Sonographer Guidelines. A baseline echocardiogram will be performed prior to the administration of DEFINITY® or MVT-100. Assessments will be made three more on

Drug - MVT-100

After randomization, MVT-100, the experimental drug, is administered via IV infusion or bolus administration and echocardiograms are subsequently obtained.

Drug - Definity

After randomization, Definity, the active comparator, is administered via IV infusion or bolus administration and echocardiograms are subsequently obtained.
