Brief Summary:
A safety study to compare the effect of two different formulations of PrEP-001 nasal powder when dosed in healthy subjects

Condition or disease Intervention/treatment Phase
Upper Respiratory Tract Infections Drug: PrEP-001 6.4 mg Drug: PrEP-001 3.2 mg Drug: Placebo Phase 1

Detailed Description:
A single centre, randomised, partially blinded placebo-controlled repeat dose study in healthy male subjects to compare the effect of two different formulations of PrEP-001 nasal powder on nasal mucosal and serum cytokine profiles when dosed for up to five days in health subjects and provide additional safety and tolerability information on active PrEP-001 nasal powder.

Primary Outcome Measures :
  1. Changes in baseline in nasal mucosal secretions and serum cytokine concentrations [ Time Frame: 5 days ]
    Changes from baseline in nasal mucosal secretions and serum cytokine concentrations when dosed for up to 5 days with 2 different formulations of PrEP 001 Nasal Powder (ie 6.4 mg Formulation B vs 6.4 mg Formulation A)


Secondary Outcome Measures :
  1. Changes in baseline in nasal mucosal secretions and serum cytokine concentrations [ Time Frame: 5 days ]
    Changes from baseline in nasal mucosal secretions and serum cytokine concentrations when dosed for up to 5 days with PrEP 001 Nasal Powder 6.4 mg Formulation B and matching placebo Formulation B

  2. Changes in baseline in nasal mucosal secretions and serum cytokine concentrations [ Time Frame: 5 days ]
    Changes from baseline in nasal mucosal secretions and serum cytokine concentrations when dosed for up to 5 days with PrEP-001 Nasal Powder (3.2 mg and 6.4 mg Formulation B

  3. Assessment of safety parameters [ Time Frame: 5 days ]
    Assessment of the following safety variables: physical examination, safety laboratory tests, vital signs, ECGs and AEs (Formulation B vs Formulation A)

  • Subjects who are study site employees, or immediate family members of a study site or sponsor employee
  • Subjects who have previously been enrolled in this study
  • History of any drug or alcohol abuse in the past 2 years
  • Regular alcohol consumption >21 units per week (1 unit = ½ pint beer, 25 mL of 40% spirit or a 125 mL glass of wine)
  • Current smokers and those who have smoked within the last 12 months. A confirmed positive urine cotinine test at screening and admission
  • Current smokers of e-cigarettes and nicotine replacement products and those who have smoked these products within the last 12 months
  • Subject who have significant history of any tobacco use at any time (total ≥10 pack years history)
  • Subjects who do not have suitable veins for multiple venepunctures as assessed by the investigator at screening
  • Clinically significant abnormal biochemistry, haematology, coagulation or urinalysis as judged by the investigator (laboratory parameters are listed in Appendix 1)

  • Positive hepatitis B surface antigen (HBsAg), hepatitis C virus antibody (HCV Ab) or human immunodeficiency virus (HIV) results
  • History of clinically significant cardiovascular, renal, hepatic, chronic respiratory or gastrointestinal disease, or psychiatric disorder, as judged by the investigator

Exceptions may apply on a case by case basis, if considered not to interfere with the objectives of the study, as agreed by the PI and sponsor's medical monitor
  • Failure to satisfy the investigator of fitness to participate for any other reason
