Number of participants with adverse events (AEs) and Serious Adverse Events (SAEs) |
Participants during hospitalization will be closely observed to assure maximal safety and to collect occurrence of all adverse event. To follow-up on the 7th day after discharge, all participants will return to the hospital for information regarding their health condition. All adverse events will be collected with special attention to occurrence of psychotomimetic and dissociative effects after study drug administration. |
up to 7 weeks |

Primary |
Change from Baseline (Day -1) in Columbia-Suicide Severity Rating Scale (C-SSRS) Total Score at Day 15 in the Double-Blind Treatment Phase |
This scale is intended to be used by individuals who have received training in its administration. The questions contained in the Columbia-Suicide Severity Rating Scale are suggested probes. Ultimately, the determination of the presence of suicidal ideation or behavior depends on the judgment of the individual administering the scale. A negative change in score indicates improvement. |
up to 15 days |

Primary |
Change from Baseline (Day -1) in The Clinician Administered Dissociative States Scale (CADSS) Total Score at 40 minutes and 2 hours after dosing in the Double-Blind Treatment Phase- ANCOVA Analysis on Ranks |
This scale is intended to be used to assess the dissociative states of participants. It contains 23 objective items, every item ranges from 0 to 4. A negative change in score indicates improvement. |
up to 2 hours |
|
Primary |
Change From pre-dosing in Modified Observer's Assessment of Alertness and Sedation (MOAA/S) Total Score at 20 minutes?40 minutes and 2 hours after dosing in the Double-Blind Treatment Phase- ANCOVA Analysis on Ranks |
The Modified Observer's Assessment of Alertness and Sedation (MOAA/S) scale is frequently used in sedation-related drug and device studies to assess a subject's level of sedation. It ranges from 0 to 5, with a score of 5 defined as awake or minimally sedated, and a score of 0 defined as general anesthesia. This scale is intended to be used by individuals who have received training in its administration. A positive change in score indicates improvement. |
up to 2 hours |
|
Primary |
Change from Baseline (Day -1) in Physician Withdrawal Checklist (PWC-20) Total Score at Day 15 in the Double-Blind Treatment Phase and Day 21 in the Follow-Up Phase- ANCOVA Analysis on Ranks |
The PWC-20 was developed to detect any potential BZ-like treatment discontinuation (withdrawal) symptoms caused by experimental anxiolytics of the non-SSRI type. A negative change in score indicates improvement. |
up to 15 days |
|
Secondary |
Cmax - maximum HS-10345 plasma concentration |
The maximum concentration of the HS-10345 in plasma after drug administration, obtained directly from the measured concentrations. |
up to 72 hours after each study drug administration |
|
Secondary |
AUC (0-24) - area under the HS-10345 plasma concentration-time curve from time 0 to 24 hours after study drug administration |
The AUC (0-24) is a measure of total plasma exposure to the drug from time point zero to 24 hours after study drug administration. |
up to 24 hours after each study drug administration |
|
Secondary |
Tmax - time to reach maximum HS-10345 plasma concentration |
The Tmax is time to reach the maximum plasma concentration (Cmax), obtained directly from the actual sampling times. |
up to 72 hours after each study drug administration |
|
Secondary |
AUC (0-inf) - area under the HS-10345 plasma concentration-time curve from time 0 to infinity time |
The AUC(0-inf) is a measure of total plasma exposure to the drug from time point zero extrapolated to infinity |
up to 72 hours after each study drug administration |
|
Secondary |
T1/2 - plasma elimination half-life for HS-10345 |
T1/2 will be calculated as 0.693/Kel |
up to 72 hours after each study drug administration |
|
Secondary |
Change from Baseline (Day -1) in Montgomery Asberg Depression Rating Scale (MADRS) Total Score at Day 2/8/15- Analysis of Covariance (ANCOVA) Analysis |
MADRS is clinician-rated scale designed to measure depression severity, and to detect changes due to antidepressant treatment. Scale consists of 10 items (apparent sadness, reported sadness, inner tension, sleep, appetite, concentration, lassitude, interest level, pessimistic thoughts, and suicidal thoughts), each of which is scored from 0 (item is not present or is normal) to 6 (severe or continuous presence of symptoms), summed for a total possible score of 0 to 60. Higher scores represent more severe condition. A negative change in score indicates improvement |
