Description of intervention(s) / exposure
UA021-AU001 is a two-part study within which parts 1 and 2 will be conducted sequentially. Each study part and stage will involve unique participants.
Part A: Single ascending dose cohorts
Part A evaluates the single-dose administration of UA021 or matched placebo (a capsule that looks the same as the study drug but has no active substances): 5mg, 15mg, 30mg, 60mg, and 120mg respectively in cohorts 1-5. Each cohort will consist of 8 participants who will each receive a single dose of investigational drug or matched placebo under fasted state (after an overnight fast of at least 8 hours prior to dosing), Healthy volunteers will stay in the clinical research unit for the entire duration of dosing and will take study drug under direct supervision of the clinical research unit staff.
Each of the SAD cohorts will be observed for at least 14 days. Safety, tolerability, and available PK data will be reviewed by the SRC for dose escalation and the actual doses to be administered may be adjusted accordingly.
Part B: Multiple ascending dose cohorts
Each cohort will consist of 8 participants who will each receive UA021 or matched placebo (a capsule that looks the same as the study drug but has no active substances): 15mg, 30mg, and 60mg given by oral administration twice daily for 14 days. after an overnight fast of at least 8 hours prior to morning dosing and, a 1 hour fast prior to the evening dose. Healthy volunteers will stay in the clinical research unit for the entire duration of dosing and will take study drug under direct supervision of the clinical research unit staff.
The actual starting dose including dose regimen for Part B and conditions for the administration of the study intervention will determined by SRC after reviewing of the safety, tolerability, and available PK data of Part A. Part B may be initiated prior to or after the completion of Part A at the discretion of the SRC. In Part B, after an observation period of at least 28 days (from the first day of dosing) and review of the safety, tolerability, and available PK data of all participants enrolled in the previous cohorts, the next actual dose cohort may be adjusted by the SRC. These dose adjustments may involve either an increase or a decrease in the planned dose or a change in the dosing frequency.

Treatment: Drugs
Comparator / control treatment
Matching placebo: The placebo capsules are a gelatine capsule shell containing white to off-white powder, consisting of the excipient’s microcrystalline cellulose, lactose monohydrate, croscarmellose sodium and magnesium stearate. The capsules have the exact same composition as the active drug product minus the active ingredient
Control group
Placebo

Outcomes
Primary outcome [1] 332779 0
Integrated safety evaluation. The safety parameters to be assessed include AEs/SAEs, and changes in clinical laboratory tests, vital signs, 12-lead ECG, and physical examinations from baseline.
Adverse events will be reported by the participant. The Investigator and any designees are responsible for detecting, documenting, and recording events that meet the definition of an AE or SAE. Events meeting the AE definition include:
• Any abnormal laboratory test results (hematology, coagulation, clinical chemistry, or urinalysis) or other safety assessments (eg, ECG, vital signs measurements, or physical examinations), including those that worsen from baseline, considered clinically significant in the medical and scientific judgment of the Investigator.
• Exacerbation of a chronic or intermittent pre-existing condition including either an increase in frequency and/or intensity of the condition.
• New conditions detected or diagnosed after study drug administration although it may have been present before the start of the study.
• Signs, symptoms, or the clinical sequelae of a suspected drug-drug interaction.
• Signs, symptoms, or the clinical sequelae of a suspected overdose of either study drug or a concomitant medication. Overdose per se will not be reported as an AE/SAE unless it is an intentional overdose taken with possible suicidal/self-harming intent. Such overdoses should be reported regardless of sequelae.

Severity categories of AE assessment include mild, moderate, and severe, as defined below-
• Mild: Asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated
• Moderate: Minimal, local, or non-invasive intervention indicated, limiting age-appropriate instrumental activities of daily living.
• Severe: Severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care activities of daily living
• Life threatening: Life-threatening consequences: urgent intervention indicated.
• Death: Death related to AE

Vital signs measurements will include tympanic body temperature, pulse rate, and blood pressure. Blood pressure and pulse rate will be assessed with a completely automated device; manual techniques will be used only if an automated device is not available.

Other reasons/comments
Other reasons
After reviewing all UA021 pre-clinical PK data and clinical PK data (Australia and Chinese), an outsider DMPK experts suggested that they should terminate the UA021-AU001 study and optimize the UA021 formulation. Considering the not good exposure and bad CV values for UA021 capsule dosages, UA021 cannot get the RP2D and will have high risk to reach the efficacy endpoints in PsO patients.

Summary
Brief summary
A first time in human study to evaluate safety, tolerability, and pharmacokinetics of UA021 capsules compared with placebo in normal healthy adult participants.
A single and multiple-ascending dose study to determine the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of UA021 in healthy adult participants. Results of this study will inform dose selection and design of studies to assess the efficacy and safety of UA021 in inflammatory diseases, including psoriasis.
