Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
DUR-928 powder for reconstitution.
In Cohort 1 and Cohort 2, each subject will receive 5 daily doses of either active DUR-928 or placebo (calcium carbonate) according to the Cohort they are participating in and the intervention they are randomised to.

Timepoint: Adverse events are collected for the duration of the study; from Day 1 (Dose 1) to Day 12 (follow-up visit).

Based on currently available animal toxicology and the first in human trial experience, adverse drug effects are not expected. Therefore, subjects will be monitored for any and all adverse events.
Secondary outcome [2] 313453 0
Evaluate dose proportionality of DUR-928 at steady state.
Timepoint [2] 313453 0
Timepoint: Dose proportionality information will be obtained by comparing plasma levels at all Pharmacokinetic timepoints, across the two dose levels (100 and 300 mg) evaluated.
Pharmacokinetic timepoints are: Dose 1(Pre-dose, and at 0.5 , 1, 1.5, 2, 2.5, 3, 3.5, 4, 6, 8, 12, and 16 hours post Dose 1), Dose 2-4 (Pre-dose), and Dose 5 (Pre-dose, and at 0.5 , 1, 1.5, 2, 2.5, 3, 3.5, 4, 6, 8, 12, 16, 24, 36 and 48 hours post Dose 5).

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
In Cohort 1 and Cohort 2, ten subjects per cohort will be randomized with a 4:1 randomization whereby 8 subjects receive DUR-928 and 2 subjects receive placebo. The dose will be provided to blinded study staff in a blinded fashion.
A central randomization schedule will be generated by the INC Research Head of Biometrics – who will have no further involvement in the study. The central Randomization schedule will be provided only to the site pharmacy staff (unblinded) who will be exclusively responsible for preparing the doses. Subjects will be assigned a randomization number in sequential order, as their eligibility is confirmed, by blinded site staff (who have no access to the Randomization schedule).

In Cohort 3, all eight subjects will receive a single dose of DUR-298 in an open-label (fasted/fed) crossover design. There is no requirement to conceal treatment allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table/schedule generated by computer software.
Masking / blinding

Other design features
In Cohort 1 and Cohort 2, ten subjects per cohort with a 4:1 randomization ratio will be treated with 8 subjects receiving DUR-928 and 2 subjects receiving placebo for a total of 2 cohorts (20 subjects total will be enrolled). The second cohort of 10 subjects continues only after the safety assessment of the first cohort.
Following review of all data from Cohort 1 and Cohort 2, eight new subjects will be enrolled into Cohort 3. All eight subjects in Cohort 3 will receive a single dose of DUR-298 in an open-label (fasted/fed) crossover design.
Phase
Phase 1
Type of endpoint/s
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.
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 and fasted vs fed state, using descriptive statistics.
Due to the exploratory nature of this study, no power or sample size calculations have been performed.

Summary
Brief summary
This research project is being conducted to look at how safe and well tolerated a new drug called DUR-928 is when given to healthy volunteers, once daily for 5 days at 2 different dose levels. The pharmacokinetics of DUR-928 will also be studied; this is done by measuring the amount of DUR-928 in the blood at different times throughout the 5 day dosing period, allowing us to evaluate how DUR-928 is handled by the body (for example how quickly it gets into the blood stream). This study will also look at the effect the food may have of the pharmacokinetics of DUR-928.
