New drug TRX-100 takes first step: safety check in healthy people

Have suitable venous access for blood sampling. 10. Be willing and able to comply with all study assessments and adhere to the protocol. Exclusion Criteria: 1. History or presence of significant cardiovascular, pulmonary, hepatic, renal, haematological, gastrointestinal, endocrine, immunologic, dermatologic or neurological disease, including any acute illness or major surgery within the past 3 months determined by the PI to be clinically significant. 2. History of surgery or hospitalisation within 30 days prior to screening, or surgery planned during the study. 3. Acute infections within 4 weeks prior to screening or current infection that requires systemically absorbed antibiotic, antifungal, antiparasitic or antiviral medications. 4. Presence or history of any abnormality or illness, including gastrointestinal surgery, liver, kidney, or other conditions, which in the opinion of the PI may affect absorption, distribution, metabolism or elimination of the study drug. 5. Any history of malignant disease in the last 5 years (excludes surgically resected skin squamous cell or basal cell carcinoma). 6. Presence of clinically relevant immunosuppression from, but not limited to, immunodeficiency conditions such as common variable hypogammaglobulinemia. 7. Use of or plans to use systemic immunosuppressive (e.g., corticosteroids by any route, methotrexate, azathioprine, cyclosporine) or immunomodulating medications (e.g., interferon) during the study and within 5 half-lives of individual agent or within 28 days (whichever is longer) prior to dosing. 8. Use of or plans to use agents (e.g., grapefruit and grapefruit products) that have clinically significant interaction with CYP3A4 or the use of any medications that could have a significantly impact on organ function (e.g., barbiturates, omeprazole, cimetidine) during the study and within 5 half-lives of individual agent or within 7 days (whichever is longer) prior to dosing. 9. History of risk factors for torsade de pointes (including a family history of long QT syndrome or sudden cardiac death) or clinically significant arrythmia. 10. Positive test results for active human immunodeficiency virus (HIV-1 or HIV-2), hepatitis B surface antigen (HBsAg), hepatitis C virus (HCV) antibodies at the screening visit. 11.

History of any drug or alcohol abuse in the past 2 years defined as \>21 units of alcohol per week for males and \>14 units of alcohol per week for females. Where 1 unit = 360 mL of beer, 150 mL wine, or 30 mL of spirits. 14. Positive drugs of abuse or alcohol breath test results at the screening visit or on Day -1. 15.

Known hypersensitivity to any of the study drug ingredients. 18. Use of any inactivated vaccinations within 14 days, or any live vaccinations within 30 days prior to the first study drug administration and during the study. Note: Participants vaccinated for COVID-19 or influenza within at least 2 weeks prior to dosing or earlier will be considered eligible for enrolment as long as they do not present with post-vaccination clinical symptoms, have a negative rapid antigen test (in the case of COVID-19), and are deemed otherwise healthy. 19. Females who are breastfeeding or planning to breast feed at any time during the study. 20.

Any other condition or prior therapy that in the opinion of the Investigator would make the volunteer unsuitable for this study, including inability to cooperate fully with the requirements of the study protocol or likelihood of noncompliance with any study requirements. 23. Any history of long-COVID infection (defined by continuation or development of new symptoms 3 months after the initial SARS-CoV-2 infection, with these symptoms lasting for at least 2 months with no other explanation). 24. Any history of severe influenza, defined as a confirmed diagnosis of influenza resulting in hospitalization, or symptoms severe enough to disrupt daily activities for more than 7 consecutive days.
