  • Participants with a positive hepatitis B surface antibody (HBsAb) due to prior vaccination are permitted.
• Any current active infection, including localized infections, or a recent history (within 1 week prior to dosing) of infection, cough, or fever, or a history of recurrent or chronic infections.
• Any disease or history of surgery that, in the opinion of the Principal Investigator or delegate, could significantly affect the absorption, distribution, metabolism, or excretion of the investigational product.
• Positive urine drug screen, urine cotinine test, or alcohol breath test.
• History of drug abuse within 6 months prior to first dosing, or substance abuse considered clinically significant by the Principal Investigator or delegate.
• History of alcohol abuse within 6 months prior to first dosing, defined as consumption exceeding 21 units per week for males or 14 units per week for females
  • (1 unit = 240 milliliter beer, 120 milliliter wine, or 30 milliliter distilled Alcohol).
• Use of depot injections or implants within 3 months prior to first dosing.
• Receipt of live or live-attenuated vaccines (bacterial or viral) within 12 weeks prior to screening, or planned receipt during the study period.
• Receipt of any vaccine, including COVID-19 vaccines, within 14 days prior to first dosing.
• Use of any drug known to induce or inhibit hepatic drug-metabolizing enzymes within 30 days or 5 half- lives (whichever is longer) prior to first dosing.
• Use of prescription medications within 14 days or 5 half-lives (whichever is longer) prior to first dosing.
• Use of over-the-counter medications or natural health products, including herbal remedies (e.g., St.
  • John's wort), traditional medicines, probiotics, dietary supplements, or sports supplements within 14 days or 5 half-lives (whichever is longer) prior to first dosing, except for occasional paracetamol up to 2 grams/day.
• Participation in another clinical research study involving an investigational or marketed drug or device within 30 days or 5 half-lives (whichever is longer) prior to first dosing; participation involving a biological product within 90 days prior to dosing; or concurrent participation in any investigational study without drug or device administration.
• Previous exposure to GV-100.

Other illness

• History of clinically significant allergic reactions, including anaphylaxis, hypersensitivity, or angioedema, to any medication, or known allergy to GV-100, related compounds, or any formulation excipients.
• Any other condition or circumstance that, in the opinion of the Principal Investigator or delegate, could interfere with study participation or compliance, which will be documented in the source records.

Lab values

• Clinically significant abnormal laboratory results at screening, in the opinion of the Principal Investigator or delegate.
• Aspartate aminotransferase (AST), alanine aminotransferase (ALT), and/or total bilirubin levels greater than 1.5 × the upper limit of normal (ULN) at screening.
• Estimated glomerular filtration rate (eGFR) Less than or equal 90 milliliter/minute/1.73 meter square at screening, calculated using the CKD-EPI equation.
• Donation of plasma or platelets within 14 days prior to dosing, or donation or loss of equals 500 milliliter of whole blood within 60 days prior to dosing.

Other

• Any clinically significant abnormal finding on physical examination, as determined by the Principal Investigator or delegate.
• Positive pregnancy test or lactation in female participants.
• Clinically significant abnormalities in ECG findings or vital signs at screening, as determined by the Principal Investigator or delegate.
• Supine systolic blood pressure greater than or equal to 160 mmHg or diastolic blood pressure greater than or equal to 95 millimeters of mercury. (mmHg) at screening after at least 5 minutes of rest. If elevated, blood pressure will be repeated two additional times, and the average of three measurements will be used to assess eligibility.

• Male or female participants, aged more than or equal 18 to less than or equal to 65 years at the time of providing informed consent, who are non-smokers (no use of tobacco or nicotine-containing products within 3 months prior to screening), with a body mass index (BMI) greater than 18.0 and less than 32.0 kilogram/meter square, and a minimum body weight of 50.0 kilogram.
• Healthy individuals, as determined by the Principal Investigator or delegate, defined as:
  • No clinically significant illness or surgical procedures within 4 weeks prior to study drug administration.
  • No clinically significant history of neurological, endocrine, cardiovascular, respiratory, hematological, immunological, psychiatric, gastrointestinal, renal, hepatic, or metabolic disorders.
• Capable of understanding the study procedures and willing to provide written informed consent prior to participation.
