Description of intervention(s) / exposure
This is a phase 1 study consisting of Part 1~Part 2. Besides the one food effect (FE) cohort, each cohort in Part 1~Part 2 is randomized, placebo-controlled, double-blinded to establish safety and tolerability in healthy volunteers (HV) following single ascending dose (SAD) and multiple ascending dose (MAD). FE is a single cohort, cross-over, 2-period study planned to evaluate the effect of food on the PK profile of open-label YA-101.

- Part 1 will assess the safety, tolerability, and PK of YA-101 administered to healthy adult volunteers as a single-ascending dose (HV SAD)
- Part 2 will assess the safety, tolerability, and PK of YA-101 administered to healthy adult volunteers as multiple-ascending doses (HV MAD), and as a single dose administered with and without food to assess food effect (HV FE).

Investigational Product: YA-101
Dose form: Suspension
Route of Administration: Oral
Dose (mg/day): Starting dose for HV SAD Cohort 1 is based on the human equivalent dose (HED) calculated from the NOAEL reported in the 28-day GLP rat toxicity study, with application of an appropriate safety factor.

SAD: Starting dose for Cohort 1 is starting at 900mg and escalating to a maximum of 9600mg of YA-101.
Subsequent dose levels for Cohort 2 and Cohort 3 will be determined based on the emerging safety, tolerability, and PK data in the preceding cohort(s).Dose frequency: once per day

FE: HV FE doses will be determined based on the emerging safety, tolerability, and PK data from SAD cohorts. In the fed state, a high-fat (approximately 50% of total caloric content of the meal) and high-calorie (approximately 800 to 1000 calories) meal is provided before dosing. YA-101 suspension will be administered within 30 minutes after the completion of meal. (Dose frequency: once per day on Day 1 and Day 4)

MAD: HV MAD doses will be determined based on the emerging safety, tolerability, and PK data from SAD cohorts. The dosing time of Part 1 is separated from the first dosing time of Part 2 by greater than 1 week. Participants from Part 1 may also participate in Part 2.

Dose frequency: twice daily for 14 days. On Day 14, subjects will only take the morning dose.

Placebo: YA-101 matching placebo will be provided for each cohort in SAD and MAD.

Study drug administration will take place on-site with oversight by study staff. Furthermore, the study drug must be dispensed under the supervision of the investigator or an authorized designee, and it should be dispensed exclusively to study subjects. The designated site staff or pharmacist will maintain records of the study drug received, dispensed to subjects, and any returned quantities.

Summary
Brief summary
Multiple system atrophy (MSA) is a rare, severe and life-threatening adult-onset neurodegenerative disease, characterized by a combination of parkinsonism, cerebellar ataxia, and autonomic dysfunction. At present, only symptomatic therapy is available for the treatment of MSA, and most of the prescribed medications are being used in an off-label manner.

YA-101 is being developed for the treatment of subjects with MSA, a serious and life-threatening condition with a high, unmet clinical need. The safety, tolerability, PK, and food effect of YA-101 will be evaluated in HV in Parts 1 and 2 of this study.

The study will be conducted in healthy volunters aged between 18-65 years . Besides the one food effect (FE) cohort, each cohort in Part 1~Part 2 is randomized, placebo-controlled, double-blinded to establish safety and tolerability in healthy volunteers (HV) following single ascending dose (SAD) and multiple ascending dose (MAD). A total of 60 participants will be enrolled in Australia.

Duration of the study
Part 1 HV SAD: Total duration of study is up to 8 days with 1-day treatment
Part 2 HV MAD: Total duration of study is up to 21 days, 14-day treatment
Part 2 HV FE: Total duration of study is up to 11 days with 1-day treatment
