Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
DUR-928 powder for constitution.
Each dose of DUR-928 is given in 60 mL of ORA-Blend (registered trademark) SF taste masking suspending vehicle. The dose will be taken orally.
Each subject will receive a single dose of DUR-928 according to the Cohort they are participating in.
The study will look at the effect of DUR-928 when given as a single dose at 2 different dose levels. All doses will be administered and supervised by study staff. The doses of the intervention are described below per cohort:
Cohort 1: 50 mg DUR-928
Cohort 2: 200 mg DUR-928
Participants will be confined to the study unit for a total of 2 nights and 3 days, inclusive of 24 hours post dose monitoring. Study participants may take part in more than one cohort, as long as a 4 week washout period is observed. All study participants will be confined to the study unit for the treatment period. Study staff will administer all doses.

Outcomes
Primary outcome [1] 296771 0
To evaluate the safety of DUR-928 in subjects with NASH following single ascending dose at three dose level compared to healthy subjects control.
Timepoint [1] 296771 0
Routine vital sign measurements (temperature [T], blood pressure [BP], pulse and respiratory rate [RR]) will be measured at screening, check-in (Day -1), pre-dose, and 1, 2, 4, 6, 12, 24 and 48 hours post-dose and at trial completion. Physical examination will be performed at screening, check-in (Day -1), and at trial completion. The physical exam done on Day -1 will be abbreviated (including general appearance and evaluation of head, eyes, ears, nose, throat and neurological system). Safety Laboratory tests (Chemistry, Hematology, and Urinalysis) will be drawn at screening, check-in (Day -1), 24 and 48 hours post-dose, and on Day 7 (trial completion). Twelve-lead ECGs will be obtained from subjects at screening, check-in (Day -1), and at approximately 2, 4, 12 and 48 hours post-dose. Additional ECGs may be obtained if clinically indicated. Timepoint: AE collection starts from the time the subject checks in (Day -1) and continues through trial completion/early termination (Day 7).
Primary outcome [2] 296839 0

Pharmacokinetic samples are collected at the following timepoints: pre-dose, and at 0.5, 1, 2, 4, 8, 12, 16, 24 and 48 hours post-dose.
Secondary outcome [1] 319298 0

Treatment
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The proposed multiple cohort study will be conducted in 2 successive cohorts evaluating 2 single-dose levels of oral DUR-928.
For each cohort 10 subjects with Nonalcoholic Steatohepatitis (NASH) will be enrolled. Of those 10 NASH subjects to be enrolled there will be an approximately equal distribution of cirrhotic and non-cirrhotic subjects.
Following enrollment of the NASH subjects in a cohort, six additional healthy subjects with normal liver function will be enrolled and receive a single dose of DUR-928. The healthy subjects will be matched to the NASH group for a given cohort by average age (+/- 10 years), average BMI (+/- 25%) and gender ratio.

Other
Other design features
2 cohorts (10 NASH Subjects and 6 Healthy Volunteers per cohort) will be given a single oral dose of DUR-928. Cohort 2 continues only after the safety assessment of Cohort 1. 32 subjects in total will be enrolled (20 NASH Subjects and 12 Healthy Volunteers).
Phase
Phase 1

Safety
Statistical methods / analysis
Safety – Safety will be evaluated by assessment of clinical laboratory tests, physical examinations including vital signs, and ECGs, and by the documentation of all spontaneously reported adverse events. Treatment-emergent AEs will be listed and summarized by dose level and cirrhotic status. Treatment-emergent changes from baseline in clinical laboratory tests, ECG, and vital signs will be derived by dose level.
Pharmacokinetics – Plasma concentration data of DUR-928 and its metabolite at each dose level will be used to calculate relevant pharmacokinetic parameters. Pharmacokinetic parameters will summarized by dose level, using descriptive statistics. At each dose level, the pharmacokinetics of DUR-928 will be compared between the NASH subjects and the healthy subjects control to support the safety review for escalation to the next dose level.
Biomarkers - The biomarker data at baseline and at each post-dose time point will be plotted and listed for each subject for evaluation of any change from baseline or over time. Baseline for each biomarker will be derived from the average.
This is an exploratory study. No power or sample size calculations have been performed.
