Brief Summary

The Phase 1 study is a randomized, double-blind, placebo-controlled, single ascending dose, multi-cohort study.

Eligibility Criteria

• Age: 18 Years - 55 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)

You may qualify if:

• Must have given written informed consent before any study-related activities are carried out and must be able to understand the full nature and purpose of the trial, including possible risks and adverse effects.
• Adult males and females, 18 to 55 years of age (inclusive) at screening.
• Body mass index ≥ 18.0 and ≤ 30.0 kg/m2, with a body weight (to 1 decimal place) ≥ 50 kg at screening.
• Be non-smokers (including tobacco, e-cigarettes and marijuana) for at least 3 months prior to first study drug administration and have a negative test for cotinine at the screening visit and at check- in on Day -1.
• Medically healthy without clinically significant abnormalities (in the opinion of the PI) at the screening visit and prior to dosing at the timepoints indicated in the Schedules of Assessments (SoA), including:
• Physical examination without any clinically significant findings;
• Systolic blood pressure in the range of 90 to 140 mmHg (inclusive) and diastolic blood pressure in the range of 40 to 90 mmHg (inclusive) after 5 minutes in supine (or semi- supine) position;
• Heart rate in the range of 40 to 100 bpm (inclusive) after 5 minutes rest in supine (or semi- supine) position;
• Body temperature (tympanic or oral) in the range 35.5°C to 37.5°C (inclusive);
• No clinically significant findings in serum chemistry, haematology, coagulation, and urinalysis tests (any of the routine laboratory test may be repeated at the discretion of the PI);
• Triplicate 12-lead ECG (taken after the volunteer has been supine (or semi-supine) for at least 5 minutes) with a QT interval corrected using the Fridericia method (QTcF) ≤ 450 msec for males and ≤ 470 msec for females and no clinically significant abnormalities.
• Female volunteers must:
• a. Be of nonchildbearing potential i.e., be surgically sterilised (hysterectomy, bilateral salpingectomy, bilateral oophorectomy at least 6 weeks before screening) or be postmenopausal, where menopause is defined as 12 months of amenorrhea in the absence of other biological causes. Females under the age of 55 years must have a documented serum follicle-stimulating hormone (FSH) level \> 40mIU/mL to confirm menopause (females who are taking Hormone Replacement Therapy (HRT) should provide evidence that they are post-menopausal or should be excluded as their post-menopausal status cannot be confirmed by measuring FSH - alternatively they would need to stop HRT to allow FSH to be measured).
• b. If of childbearing potential (defined as any female who has experienced menarche and who has not undergone surgical sterilisation and is not postmenopausal), the participant:
• Must have a negative serum test at the screening visit and a negative urine pregnancy test within 24 hours prior to the start of study drug;

You may not qualify if:

• 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 (participants with resolved childhood asthma may be included in the study).
• Current infection that requires systemically absorbed antibiotic, antifungal, antiparasitic or antiviral medications.
• Suffer from frequent or recurrent infections (defined as ≥3 occurrences in the 12 months preceding first study drug administration or 2 occurrences in the 6 months preceding first study drug administration).
• Any history of malignant disease in the last 10 years (excludes surgically resected skin squamous cell or basal cell carcinoma).
• Presence of clinically relevant immunosuppression from, but not limited to, immunodeficiency conditions such as common variable hypogammaglobulinemia.
• Use of or plans to use systemic immunosuppressive (e.g., corticosteroids, methotrexate, azathioprine, cyclosporine) or immunomodulating medications (e.g., interferon) during the study or within 3 months prior to the first study drug administration (prior use of nasal sprays for hayfever may be permitted if used \> 30 days prior to study drug administration or alternatively at the discretion of the PI).
• History of risk factors for torsade de pointes (including a family history of long QT syndrome or sudden cardiac death) or a known arrythmia.
• Liver function test results elevated more than 1.5-fold above the upper limit of normal (ULN) for gamma glutamyl transferase (GGT), bilirubin (total, conjugated and unconjugated), alkaline phosphatase (ALP), aspartate aminotransferase (AST) or alanine aminotransferase (ALT). Volunteers with ALP and/or ALT/AST above the limits specified may be included, at the discretion of the PI, if the levels are unaccompanied by clinical signs and are determined to be normal variants.
• Positive test results for active human immunodeficiency virus (HIV), hepatitis B surface antigen (HBsAg), hepatitis C virus (HCV) antibodies or Quantiferon Gold® (Tuberculosis (TB) infection) at the screening visit.
• Estimated creatinine clearance (CrCl) \< 60 mL/min using the Cockcroft-Gault formula or serum creatinine more than 1.5-fold above the ULN.
• History of substance abuse or alcohol abuse within 12 weeks prior to the screening visit (defined as more than an average of 14 standard drinks per week or regular consumption of more than 4 standard drinks on any one day; where 1 standard drink is 10 g of pure alcohol and is equivalent to 285 mL beer \[4.9% Alc./Vol\], 100 mL wine \[12% Alc./Vol\], 30 mL spirit \[40% Alc./Vol\]).
• \. Positive drugs of abuse or alcohol breath test results at the screening visit or at check-in (Day -1).
• \. Use of any prescription or over-the-counter medication (including herbal products, and hormone supplements) within 10 days or 5 half-lives of the medication (whichever is longer) prior to the first study drug administration - exceptions include occasional use of paracetamol (doses of 500 mg up to every 6 hours or 2 g per day maximum for no more than 3 consecutive days), ibuprofen (doses of 400 mg up to every 6 hours or 1.2 g per day maximum for no more than 3 consecutive days), topical ointments, and vitamins or dietary supplements.
• \. Demonstrated clinically significant (required intervention, e.g., emergency room visit, epinephrine administration) allergic reactions (e.g., food, drug, or atopic reactions, asthmatic episodes) which, in the opinion of the PI, would interfere with the volunteer's ability to participate in the trial.
• \. Known hypersensitivity to any of the study drug ingredients. 17. Use of any vaccinations within 14 days (within 4 weeks for live virus vaccines) prior to the first study drug administration.
