A Comparison of Technegas® and Xenon 133 Planar Lung Imaging in Subjects Referred for Ventilation Scintigraphy

Phase 3 within-subject non-inferiority trial of Technegas ventilation imaging compared to
Xenon-133 (Xe-133) ventilation imaging to demonstrate the non-inferiority of Technegas
compared to Xe-133 ventilation studies with respect to subject pulmonary ventilatory
distribution. Subjects will undergo site-specific standard of care (SOC) Xe-133 imaging per
medical needs followed by Technegas ventilation imaging per study protocol.

This is a Phase 3 within-subject non-inferiority trial of Technegas ventilation imaging
compared to Xenon-133 (Xe-133) ventilation imaging to demonstrate the non-inferiority of
Technegas compared to Xe-133 ventilation studies with respect to subject pulmonary
ventilatory distribution. Subjects will undergo site-specific standard of care (SOC) Xe-133
imaging per medical needs followed by Technegas ventilation imaging per study protocol.
Primary assessments of efficacy will be based on three blinded readers' assessments of the
Technegas and Xe-133 ventilation images in independent reading sessions.

Inclusion Criteria:

- Male or female subject at least 18 years of age.

- Subject is a candidate for ventilation imaging.

- Subject must be willing and able to provide informed consent.

- Subject must be stable and able to undergo Xe-133 planar imaging and Technegas planar
imaging.

- Subject must be willing and agree to complete study procedures.

- Subject is using adequate birth control, if female and fertile. Adequate birth control
