Testing NS-136 in healthy individuals

A Phase 1, Double-blind, Placebo-controlled Study to Evaluate the Safety, Tolerability, and PK of Single and Multiple Ascending Oral Doses and Food Effect of NS-136 in Healthy Subjects

This study is testing a new drug called NS-136 in healthy people to see how safe it is and how it works in the body compared to a placebo.

Quick facts

• Phase: PHASE1
• Study type: Interventional
• Enrollment: 76 (estimated)
• Ages: 18 Years to 65 Years
• Sex: All
• Sponsor: NeuShen Therapeutics (industry)
• Locations: 2 sites (Adelaide, South Australia and 1 other locations)
• Trial ID: NCT06345703 on ClinicalTrials.gov

What this trial studies

This clinical trial aims to evaluate the safety and tolerability of NS-136 in healthy subjects. It will assess the pharmacokinetic profile of NS-136 under a specific dosing regimen. Participants will receive either the NS-136 tablet or a placebo, allowing researchers to compare the effects of the drug against a control group. The study is designed to gather important data on how the drug behaves in the body and its potential side effects.

Who should consider this trial

Good fit: Ideal candidates for this study are healthy males and females aged 18-65 with a BMI between 18.00 and 32.00 kg/m2.

Not a fit: Patients with underlying health conditions or those who have participated in other clinical trials recently may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the safety and pharmacokinetics of NS-136, paving the way for future therapeutic applications.

How similar studies have performed: While this approach is common in early-phase trials, the specific drug NS-136 has not been previously tested in humans, making this a novel investigation.

2. Individuals who are intolerant to venipuncture/venous catheterization or blood fainting or needle phobia;
3. Positive results for hepatitis B surface antigen (HBsAg), hepatitis C virus antibody (Anti-HCV), human immunodeficiency virus antibody (Anti-HIV) during the screening period;
4. Average daily smoking of more than 5 cigarettes in the 3 months prior to screening, or inability to stop using any tobacco products (including nicotine products) during the trial;
5. Excessive alcohol consumption or weekly alcohol intake exceeding 14 units of alcohol in the 4 weeks prior to screening (1 unit equals 10 grams of pure alcohol, alcohol content of different alcoholic beverages is indicated by volume ratio, approximately 1 alcohol unit is equal to 35 mL of 50° liquor or 350 mL of 5° beer), or unwillingness to stop drinking alcohol or consuming any products containing alcohol during the trial, or positive alcohol test upon screening and admission (repeated test is allowed once at investigator's discretion);
6. Excessive intake of tea, coffee, or caffeinated beverages (more than 8 cups/day, 1 cup = 250 mL) in the 3 months prior to screening, or inability to stop consuming any beverages or foods containing caffeine, any beverages or foods rich in purines, or grapefruit and other substances that may affect drug absorption, distribution, metabolism, or excretion during the trial;
7. History of drug abuse within the past year prior to the first dose, or positive results in a multi-drug urine screening test upon screening period and admission. Repeated test is allowed once at investigator discretion;
8. History of definite neurological or psychiatric disorders (including epilepsy, migraines, dementia, depression or bipolar disorder, schizophrenia, etc.); history of prolonged QTc interval; immunodeficiency or immunosuppressive diseases, malignant neoplastic diseases; chronic cardiovascular, hepatic, renal, endocrine, respiratory, hematological (including coagulation), digestive system diseases, cholecystectomy, Gilbert's Syndrome or resolved childhood asthma;
9. Underwent major surgery within the past 6 months prior to the first dose (such as coronary artery bypass grafting, hepatectomy, gynecological surgery, etc.); occurrence of acute neurological, digestive, respiratory, circulatory, endocrine, hematological, or other systemic diseases that may affect the absorption, distribution, metabolism, excretion, and safety evaluation of the investigational product within 3 months prior to screening judged by investigator;
10. Donated blood or experienced blood loss ≥400 mL within the 3 months prior to the first dose; difficulties in venous blood collection; planned blood donation during the study or within 1 month after the study;
