Description of intervention(s) / exposure
This is a randomized, double-blind, placebo-controlled dose-escalation study to evaluate the safety, tolerability and Pharmacokinetics (PK) of ACT004 after administration of single (Part A) and multiple (Part B) oral doses in healthy adult subjects. Approximately five sequential dose cohorts (single oral doses of 100, 200, 400, 600 and 800 mg ACT004) will be evaluated as single ascending doses (SAD) in Part A. Select appropriate dose cohort(s) (seven consecutive days for respectively daily oral) based on the Part A and safety review committee (SRC), which will be evaluated as multiple ascending doses (MAD) in Part B. For each dose cohort in this study, ten healthy subjects will be randomized in an 8:2 ratio to receive either ACT004 or a placebo in SAD and MAD. Based on the safety, tolerability, and PK data of the previous dose cohort, the SRC will make decisions on whether to proceed with dose escalations, dosage adjustments, use of sentinel subjects or termination of the study, etc. Higher dose cohort(s) may be attempted additionally if judged necessary by the SRC. Each subject will receive only one dosing regimen in this study. The proposed doses/dosing frequency of ACT004 may be adjusted over the course of the whole study, and cohorts may be added or removed depending on the exposure of ACT004 in humans.
* Part A - SAD study (Cohort A1-A5) Approximately 35 days: Healthy subjects will be screened within 28 days prior to dosing. Subjects will be admitted to the clinical site on Day -1 and dosed orally on Day 1 under fasting conditions (fasting for at least 10 hours) with approximately 240 mL of warm water . Following completion of all safety assessments and sampling for Pharmacokinetic analysis, subjects will be monitored at clinical site and discharged on Day 4 and return for an end of study (EOS) visit on Day 7. EOS visit will also be the early termination (ET) visit if required (to be completed within 3 days of ET wherever possible). ACT004 capsule will be administered to subjects orally at a starting dose of 100 mg and increased to 200, 400, 600 and 800 mg in sequential dosing cohorts. Dose escalation will be based on the SRC review of blinded safety data including Adverse Event (AE) data, clinical laboratory results, ECGs, vital signs and physical examinations findings, and PK data up to and including Day 7. Once a minimum of 10 subjects randomized in a given cohort complete the Day 7 study visit, all safety and PK data will be reviewed by the SRC prior to dose escalation to the next dose cohort. For the safety of subjects, two sentinel subjects will be randomly dosed (ACT004: placebo = 1:1) at least 24 hours prior to the remaining subjects in each cohort. Once safety is confirmed, the remaining 8 subjects will be dosed at 7:1 to receive ACT004 or a placebo.
*Part B - MAD study (Cohort B1) Approximately 45 days : MAD cohorts may commence at the discretion of the SRC, after the safety data from a SAD cohort at a higher dose (and hence higher exposure) have been evaluated. Dosing will commence with the lowest dose cohort (B1). subjects will receive either ACT004 capsule or placebo once daily with approximately 240 mL of warm water for 7 consecutive days from Day 1 to Day 7. Subjects should receive ACT004 or placebo once daily at the same time whenever possible. Subjects will be required to take the study drug on an empty stomach (fasting for at least 10 h) in the morning of Day 1 and Day 7, and have breakfast 2 hour after dosing, lunch and dinner 4 and 10 hours after dose. The planned dose regimen for Part B (MAD study) may be adjusted by the SRC according to safety, tolerability, and PK results of Part A. Healthy subjects will be screened within 28 days prior to dosing and admitted to the clinical site on Day -1. Eligible subjects will be randomized into appropriate dose cohort(s) in an 8:2 ratio to receive ACT004 or placebo on Day 1 to Day 7. Following completion of all PK sample collection and safety assessments, subjects will be discharged on Day 10 and followed up on Day 14. Dose escalation will be based on SRC review of blinded safety data including AE data, clinical laboratory results, ECGs, vital signs and physical examinations findings up to and including Day 14 along with PK data up to and including Day 10. Once a minimum of 10 subjects randomized in a given cohort complete the Day 14 study visit, all safety and PK data will be reviewed by the SRC prior to dose escalation to the next dose cohort.
Telemetry monitoring will be performed continuously from pre-dose to 6 hour post dose in both Part A and Part B. Telemetry monitoring includes blood pressure, heart rate, and respiratory rate. During telemetry monitoring items as vital signs or 12 Lead- ECG can be monitored once.
Adherence to the intervention will be done via Drug Accountability.

Placebo will be supplied as gelatin capsules in bottles and labeled in accordance with International Committee on Harmonization of Good Clinical Practice (ICH GCP) and any other local regulatory requirements. Placebos are composed of 102mg of lactose hydrate, 1 mg of sucorse octaacetate and 1mg of polyethylene glycol 6000.
* Part A - SAD study: For the safety of subjects, two sentinel subjects will be randomly dosed (ACT004: placebo = 1:1) at least 24 hours prior to the remaining subjects in each cohort. Once safety is confirmed, the remaining 8 subjects will be dosed in 7:1 to receive ACT004 or placebo..
* Part B - MAD study: MAD cohorts may commence at the discretion of the SRC, after the safety data from a SAD cohort at a higher dose have been evaluated. Healthy subjects will be screened within 28 days prior to dosing and admitted to the clinical site on Day -1. Eligible subjects will be randomized into appropriate dose cohort(s) in an 8:2 ratio to receive ACT004 or placebo on Day 1 to Day 7. Following completion of all PK sample collection and safety assessments, subjects will be discharged on Day 10 and followed up on Day 14.

Statistical methods / analysis
Pharmacokinetic analysis:
Plasma concentration-time profiles will be obtained by plotting mean concentrations against blood sampling time points. Plasma concentrations at each blood sampling time point are subject to descriptive statistical analysis.
Descriptive statistical analyses will be performed for PK parameters by groups.
Safety analysis:
AEs will be coded using the preferred terms (PT) from Medical Dictionary for Regulatory Activities (MedDRA) of the most recent version at the time of database lock and grouped by system organ class (SOC). The severity of AEs will be graded. The number of events, number and percentage of subjects will be summarized for all treatment-emergent adverse events (TEAEs, defined as any AE occurring from the start of dosing to the end of the study), SAEs, study drug-related TEAEs, study drug-related SAEs, and TEAEs leading to study discontinuation by SOC, PT, and group. In addition, the severity of TEAEs, SAEs and their relationship to study drug will also be summarized by SOC, PT, and cohort.
Descriptive statistical analyses will be performed for the baseline values, post-dose values, and changes from baseline for vital signs, physical examinations, laboratory tests, and 12-lead ECG.

Summary
Brief summary
This is a randomized, double-blind, placebo-controlled dose-escalation study to evaluate the safety, tolerability and PK of ACT004 after administration of single (Part A) and multiple (Part B) oral doses in healthy adult subjects. Approximately five sequential dose cohorts (single oral doses of 100, 200, 400, 600 and 800 mg ACT004) will be evaluated as single ascending doses (SAD) in Part A. Select appropriate dose cohort(s) (seven consecutive days for respectively daily oral) based on the Part A and safety review committee (SRC), which will be evaluated as multiple ascending doses (MAD) in Part B. For each dose cohort in this study, ten healthy subjects will be randomized in an 8:2 ratio to receive either ACT004 or placebo in SAD and MAD. Based on the safety, tolerability, and PK data of the previous dose cohort, the SRC will make decisions on whether to proceed with dose escalations, dosage adjustments, use of sentinel subjects or termination of the study, etc. Higher dose cohort(s) may be attempted additionally if judged necessary by the SRC. Safety data up to Day 7 in SAD study and up to Day 14 in MAD study will be reviewed prior to dose escalation by the SRC. Dosing will be escalated in a sequential fashion if approved by the SRC. Dose escalations will be terminated when there are 1/2 or more subjects with grade 2 adverse events (AEs), or 1/3 or more subjects with grade 3 AEs, or 1 or more subjects with serious adverse events (SAEs) related to the study drug in the current dose cohort. Each subject will receive only one dosing regimen in this study. The proposed doses/dosing frequency of ACT004 may be adjusted over the course of the whole study, and cohorts may be added or removed depending on the exposure of ACT004 in humans. For the safety of subjects, two sentinel subjects will be randomly dosed (ACT004: placebo=1:1) at least 24 hours prior to the remaining subjects in each cohort. Once safety is confirmed, the remaining 8 subjects will be dosed in 7:1 to receive ACT004 or placebo.

Public notes
This is the first clinical study of ACT004 to evaluate the safety, tolerability and PK profile in a population. The selection of healthy adult volunteers for this human study meets ethical requirements. At the same time, the sample homogeneity of healthy people is high, which can reduce the influence of individual differences on safety and PK characteristics results; on the other hand, selecting healthy people can avoid the impact of disease burden and concomitant medications on the safety evaluation of experimental drugs, and healthy people can help researchers observe more reliable toxicity data. This study is also randomized and double-blinded with regard to treatment with ACT004 and matching placebo in order to prevent bias in treatment allocation and in the assessment of effect. The Investigator, as well as the Sponsor and their representatives involved in the monitoring or conducting the study, and the subjects will all be blinded to the study drug codes. Step 7 -Recruitment- (This will be deleted)- Date of last data collection - the longest one for data collection is the 3 months of pregnancy. Therefore, this has been updated as 15-Feb-2024
