Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Investigation product: KER-047 to be administered as an oral capsule or liquid with KER-047 dissolved in SyrSpend. Intervention adherence will be assessed by sponsor representative monitors. The monitors will asses compliance with the study protocol by performing an audit of nurses notes and pharmacy logs.
The study consists of two parts:
1. Single ascending dose (SAD) randomized 3 (study drug): 1 (placebo) in up to 10 cohorts.
Cohort 1: 1mg single oral dose administered on day 1
Cohort 2: 3mg single oral dose administered on day 1
Cohort 3: 10mg single oral dose administered on day 1
Cohort 4: 30mg single oral dose administered on day 1
Cohort 5: 100mg single oral dose administered on day 1
Cohort 6: 300mg single oral dose administered on day 1
Cohort 7: 30mg single oral dose administered on day 1
Cohort 8: 100mg single oral dose administered on day 1
Cohort 9: 300mg single oral dose administered on day 1
Cohort 10: 450mg single oral dose administered on day 1

2. Multiple ascending dose (MAD) The dose of the first MAD cohort will be determined by the Safety Review Committee (SRC), based on the PK and safety results of the SAD study. Dose increases for the MAD will be determined from the SAD. Up to 6 cohorts will be randomized 4 (study drug): 1 (placebo) with once daily, twice daily or every other day dosing for seven (7) or fourteen (14) days.
Intervention code [1] 313652 0
Treatment: Drugs
Comparator / control treatment
The placebo formulation has the same size, shape, color, and qualitative composition as the investigational product (IP), with the exception that the IP drug substance has been replaced with microcrystalline cellulose. For SAD Cohorts 7 and 8 the liquid placebo formulation will be a mixture of SyrSpend and water, and match the KER-047 liquid presentation in volume. For SAD Cohorts 9 and 10 and all MAD Cohorts, a microcrystalline cellulose powder (MCC) will be added to the SyrSpend/Water mixture to mask the opacity of the liquid KER-047, and will match the KER-047 liquid presentation in volume.
Control group
Placebo

Safety
Statistical methods / analysis
The sample size is customary for Phase 1 studies evaluating safety, and PK parameters; it is not based on statistical hypothesis testing.
In general, data will be summarized using descriptive statistics (mean, median, standard deviation, minimum and maximum) or frequency counts and percentages, as appropriate to the type of data. Baseline will be defined as the last available, valid, non-missing assessment prior to dosing.
Only data from protocol scheduled visits/time points will be included in the summary tables. Data from unscheduled visits/time points will not be included in the summary tables but will be included in the figures and listings.

Summary
Brief summary
KER-047 is being developed by Keros Therapeutics Australia Pty Ltd as a potential treatment for Fibrodysplasia ossificans progressive (FOP).
