Detailed Description

A Phase 1 Single Dose Study to investigate the safety, tolerability and Pharmacokinetic profile of SNP-630 in Health Subjects To evaluate the safety, tolerability and Pharmacokinetic profile of SNP-630 when oral administered to healthy subjects. This is a phase 1, open-label, single-dose study to assess its safety, tolerability and pharmacokinetic profile of SNP-630 in 14 health volunteers. Subjects will receive oral SNP-630 at a dose of 720 mg to assess its safety, tolerability and pharmacokinetic profile. After written informed consent has been obtained, all screening procedures and tests that establish study eligibility will be performed within 28 days prior to day -1 visit. The primary endpoint is to assess the following variable: Clinical safety observations will include Adverse Events (AEs), vital sign measurements, 12-lead ECG and clinical laboratory assessments. Safety data will be tabulated and where appropriate, analyzed by the use of descriptive statistics. Safety data will be tabulated by system organ class and preferred term and will be further classified by relationship to treatment. The probability of safety events will be estimated and with associated 95% corresponding confidence intervals for each cohort using the binomial distribution. Participants are free to withdraw from participation in the study at any time upon request


  • Drug: SNP-630
    • Subjects will receive one single dose of SNP-630 at Day 1. Blood and urine samples will be obtained to determine the PK of orally administered SNP-630.

Arms, Groups and Cohorts

  • Experimental: test drug
    • Powder for oral solution of SNP-630.

Clinical Trial Outcome Measures

Primary Measures

  • Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs):
    • Time Frame: 6 days
    • An AE is any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product. An SAE is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged in-patient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.

Secondary Measures

  • Pharmacokinetic profile of SNP-630
    • Time Frame: 6 days
    • Concentrations of SNP-630 and it metabolites in plasma and urine will be measured by a specific and sensitive LC/MS/MS method developed in the laboratory of Clinical Pharmacokinetic Laboratory of Tri-Service General Hospital. According to the pharmacokinetic parameters of SNP-630 and its metabolites in health subjects oral SNP-630 to assess the safety information.The study will be conducted to validate the precision, accuracy (including with-run and between-run variation), linearity, specificity, reproducibility, limit of quantitation based on recovery studies. Assays will be performed in the laboratory of Clinical Pharmacokinetic Laboratory of Tri-Service General Hospital. Spiked samples of known concentrations will be analyzed together for quality control of the assay method.

Participating in This Clinical Trial

Inclusion Criteria

  • A subject can participate in the study only if all the following criteria are met: 1. Between 20 and 45 years 2. Body weight 55 – 95 kg and body mass index (BMI) within the range 19 – 30 kg/m2 3. Healthy as determined by the investigator or medically qualified designee based on a medical evaluation including medical history, physical examination, laboratory tests, vital signs and 12-lead ECG. (A subject with a clinically insignificant abnormality or laboratory parameter(s) may be included only if the Investigator documents that the finding is unlikely to represent a safety risk and will not interfere with the study procedures.) 4.

Has participated in a clinical trial and has received an investigational product within 3 months prior to dosing 9. Pregnant or lactating 10. Anticipated requirement for any prescription medication during the study. 11. History of sensitivity to any of the study medications, or components thereof or a history of anaphylaxis or severe allergy to drug or other substances 12.
