What is being measured
The primary outcome is the main question the study is designed to answer.
Percent Change From Baseline in Liver Fat by Magnetic Resonance Imaging-Proton Density Fat Fraction (MRI- PDFF) at Week 16
MRI-PDFF utilized a gradient echo sequence with low flip angle (FA) to minimize T1 bias, corrected T2* decay (due to iron overload) via modeling of the fat signal as a superposition of multiple frequency components from 5 different lipid types, and was applied in each of the 9 Couinaud segments. This technique improved fat quantification accuracy for the entire liver permitting quantification of small differences/changes following pharmacological intervention.
Measured: Baseline (between Day -14 and Day 1), Week 16
Secondary outcomes (5)
Percent Change From Baseline in Alanine Aminotransferase at Week 16
Potential improvement in liver function was denoted by reduction in alanine transaminase (ALT)
Measured: Baseline (Day 1 pre-dose), Week 16
Number of Participants With Treatment-Emergent Adverse Events
An AE was any untoward medical occurrence in a study subject administered a product or medical device. A serious AE (SAE) is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; life-threatening; initial or prolonged inpatient hospitalization; persistent or significant disability/incapacity; congenital anomaly/birth defect. Any such events with initial onset or increasing in severity after the first dose of study treatment were counted as treatment-emergent.
Measured: From first dose of study treatment (Day 1) up to Week 20
Number of Participants With Laboratory Abnormalities
Following laboratory parameters were assessed against pre-defined abnormality criteria: hematology (hemoglobin, hematocrit, erythrocytes, reticulocytes, platelets, leukocytes, lymphocytes, neutrophils, basophils, eosinophils, monocytes, activated partial thromboplastin time, prothrombin time [PT], PT/international normalized ratio, reticulocytes); chemistry (indirect bilirubin, direct bilirubin, protein, albumin, blood urea nitrogen, creatinine, creatine kinase, urate, calcium, sodium, potassium, chloride, bicarbonate, urine urobilinogen); urinalysis (pH, urine glucose, urine ketones, urine protein, urine hemoglobin, nitrites, leukocyte esterase, urine erythrocytes, urine leukocytes, urine hyaline casts, urine bilirubin, granular casts).
Measured: From first dose of study treatment (Day 1) up to Week 20
Number of Participants With Vital Signs Data Meeting Predefined Criteria
Vital signs categorical summarization criteria: 1) sitting systolic blood pressure (SBP) <90 or >180 millimeters of mercury (mmHg); 2) sitting diastolic blood pressure (DBP) <50 mmHg or >110 mmHg; 3) sitting pulse rate <40 or >120 beats per minute (bpm); 4) change from baseline (increase or decrease) in sitting DBP greater than or equal to (>=) 20 mmHg; 5) change from baseline (increase or decrease) in sitting SBP >=30 mmHg.
Measured: From first dose of study treatment (Day 1) up to Week 18
Number of Participants With 12-Lead Electrocardiogram (ECG) Data Meeting Predefined Criteria
ECG categorical summarization criteria: 1) QRS interval (time from ECG Q wave to the end of the S wave corresponding to ventricle depolarization) >=140 milliseconds (msec); 2) QRS interval >=50% change from baseline; 3) PR interval (the interval between the start of the P wave and the start of the QRS complex, corresponding to the time between the onset of the atrial depolarization and onset of ventricular depolarization) >=300 msec; 4) PR interval >=25% change when baseline is >200 msec or >=50% change when baseline is <=200 msec; 5) QT interval (time from ECG Q wave to the end of the T wave corresponding to electrical systole): absolute value of >=500 msec; 6) QTcF interval (QT corrected for heart rate using Fridericia's formula) absolute value of 450 to <480 msec; 7) QTcF interval: absolute value of 480 to <500 msec; 8) QTcF interval: absolute value >=500 msec; 9) QTcF interval: a change from baseline of 30 to <60 msec; 10) QTcF interval: a change from baseline >=60 msec.
Measured: From first dose of study treatment (Day 1) up to Week 18

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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 10 Mar 2020). 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?
Percent Change From Baseline in Liver Fat by Magnetic Resonance Imaging-Proton Density Fat Fraction (MRI- PDFF) at Week 16 (time frame: Baseline (between Day -14 and Day 1), Week 16). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03248882, which also lists 2 linked publications.
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.
How often is this information updated?
