What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Mean Total Visualization Score of Qualitative Endocardial Border Delineation (EBD) of the 12 Segments of the Left Ventricle (LV) Wall in Standard Apical 4-chamber (A4C) and Apical 2-chamber (A2C)

    Visualization of each of the 12 segments of the LV wall in standard A4C and A2C views were measured by the qualitative EBD visualization scale: score 0 =no visualization of the LV endocardial border; 1 =poor visualization; 2 =fair visualization; 3 =good/optimal visualization. The total LV EBD score was calculated as the sum of the individual scores assigned to each of the 12 LV wall segment and the total score ranged from 0 (no visualization of the LV endocardial border) to 36 (good/optimal visualization). A higher score indicated better visualization. The total score of qualitative EBD visualization scale were reported by reader (independent blinded), non-contrast and dose levels.

    Measured: Images were captured during the study echocardiogram (0 to 30 minutes) on Day 1 and blinded image evaluations (BIE) were carried out at the study core laboratory following image transfer

Secondary outcomes (12)
  1. Number of Participants With Treatment-emergent Adverse Events (TEAEs)

    An Adverse Event (AE) was any untoward medical occurrence in a participant administered a pharmaceutical product and which did not necessarily had to have causal relationship with treatment. TEAEs were defined as AEs that starts or worsens at or after the time of first dosing of OPTISON.

    Measured: 0- 72 hours

  2. Change From Baseline in Systolic and Diastolic Blood Pressure

    Systolic and diastolic blood pressure were measured from the arm contra-lateral to the site of OPTISON administration whenever possible and before measurement, participants rested for at least 5 minutes (if possible).

    Measured: Baseline (pre-dose), and at 10 and 60 minutes post last dose on Day 1

  3. Change From Baseline in Heart Rate

    Before heart rate was measured, participants rested for at least 5 minutes (if possible).

    Measured: Baseline (pre-dose), and at 10 and 60 minutes post last dose on Day 1

  4. Change From Baseline in Respiratory Rate

    Before respiratory rate was measured, participants rested for at least 5 minutes (if possible).

    Measured: Baseline (pre-dose), and at 10 and 60 minutes post last dose on Day 1

  5. Change From Baseline in Oxygen Saturation as Measured by Pulse Oximetry

    Oxygen saturation was measured by pulse oximetry. Before oxygen saturation was measured, participants rested for at least 5 minutes (if possible).

    Measured: Baseline (pre-dose), and at 10 and 60 minutes post last dose on Day 1

  6. Number of Participants With Clinically Significant Abnormality in Physical Examination Findings

    Participants underwent assessments including general appearance, respiratory, cardiovascular and neurological (motor function, level of consciousness, sensory function) examination. Any abnormal clinically significant physical examination findings were based on investigator decision.

    Measured: From first dose (Day 1) of study drug to 60 minutes post last dose on Day 1

  7. Change From Baseline in 12-lead Electrocardiograms (ECGs) Parameters

    Change from baseline in PR, QRS, QT, Bazett's formula corrected QT (QTcB), Fridericia's formula corrected QT (QTcF) and RR intervals expressed in millisecond (ms) were reported.

    Measured: Baseline (pre-dose), and at 10 and 30 minutes post last dose on Day 1

  8. Number of Participants by Degree of Left Ventricular Opacification (LVO) Assessed by Visual Peak Contrast Intensity

    LVO peak contrast intensity was determined by readers (independent blinded) using a categorical scale as None, Low, Medium, High or Blooming, where, None = Absence of contrast signal; Low = Limited capacity to make a diagnostic assessment; Presence of contrast signal does not improve diagnostic interpretability to a great degree; Medium = Good capacity to make a diagnostic assessment; Contrast signal facilitates diagnostic interpretability to a good degree; High = Optimal capacity to make a diagnostic assessment; Contrast signal facilitates diagnostic interpretability to a high degree; Blooming = Oversaturation of the signal disrupts diagnostic interpretability. Tissue boundaries become challenging to delineate. There may be excessive acoustic shadowing in the far-field of the image. Number of participants by degree of LVO assessed by visual peak contrast intensity was presented by readers and dose levels.

    Measured: Images were captured during the study echocardiogram (0 to 30 minutes) on Day 1 and blinded image evaluations (BIE) were carried out at the study core laboratory following image transfer

  9. Number of Participants by Grade of Left Ventricular Opacification (LVO) Assessed by Peak Left Ventricular (LV) Contrast Filling

    Peak LV contrast filling for LVO was categorized as: 0 = none (0 percent [%] filling); 1 = faint (around 33% filling); 2 = intermediate (around 67% filling); 3 = full (100% filling) and data were presented by readers (independent blinded) and dose levels.

    Measured: Images were captured during the study echocardiogram (0 to 30 minutes) on Day 1 and blinded image evaluations (BIE) were carried out at the study core laboratory following image transfer

  10. Number of Participants by Contrast Enhancement Duration in the Left Ventricular (LV) Chamber

    Contrast enhancement duration was determined from the time the contrast appeared in the LV to the time the contrast almost dissipated from the left chamber. 3 independent blinded reader performed evaluation.

    Measured: Images were captured during the study echocardiogram (0 to 30 minutes) on Day 1 and blinded image evaluations (BIE) were carried out at the study core laboratory following image transfer

  11. Number of Participants by Diagnostic Confidence of Left Ventricular Endocardial Border Delineation (LV EBD) and Wall Motion for Contrast and Non-Contrast Enhanced Images

    Diagnostic confidence for the assessment of LV EBD and wall motion was scored for non-contrast and OPTISON-enhanced echocardiographic acquisitions separately using a 4-point scale which ranged from ranged 0 to 4, where 0 = no confidence, 1 = low confidence, 2 = moderate confidence, 3 = high confidence. A higher score indicates better confidence level. Data were presented by reader (independent blinded), non-contrast and dose levels.

    Measured: Images were captured during the study echocardiogram (0 to 30 minutes) on Day 1 and blinded image evaluations (BIE) were carried out at the study core laboratory following image transfer

  12. Number of Participants by Diagnostic Confidence of Left Ventricular Ejection Fraction (LVEF) for Non-contrast and OPTISON Enhanced Echocardiography

    Diagnostic confidence for the evaluation of LVEF was calculated using the formula: (end diastole volume - end systole volume)/(end diastole volume) was scored for non-contrast and OPTISON-enhanced echocardiographic acquisitions separately using a 4-point scale which ranged from 0 to 3, where 0 = no confidence, 1 = low confidence, 2 = moderate confidence, 3 = high confidence. A higher score indicates better confidence level. Data were presented by reader (independent blinded), non-contrast and dose levels.

    Measured: Images were captured during the study echocardiogram (0 to 30 minutes) on Day 1 and blinded image evaluations (BIE) were carried out at the study core laboratory following image transfer

The record says: finished, as of the sponsor's last update on 17 May 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 17 May 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Mean Total Visualization Score of Qualitative Endocardial Border Delineation (EBD) of the 12 Segments of the Left Ventricle (LV) Wall in Standard Apical 4-chamber (A4C) and Apical 2-chamber (A2C) (time frame: Images were captured during the study echocardiogram (0 to 30 minutes) on Day 1 and blinded image evaluations (BIE) were carried out at the study core laboratory following image transfer). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
