Inclusion Criteria:
Participants must satisfy all of the following inclusion criteria before being allowed to enter the study:
1. Have given written informed consent approved by the relevant Ethics Committee (EC) governing the site, indicating that they understand the purpose of and procedures required for the study and are willing to participate in the study.
2. Male participants between 18 and 55 years of age, inclusive at screening.
3. Otherwise healthy with no clinically significant abnormalities as determined by medical history, physical examination, blood chemistry assessments, haematological assessments, coagulation and urinalysis, measurement of vital signs, and ECG. Isolated out-of-range values judged by the PI (or designated physician) to be of no clinical significance can be allowed. This determination must be recorded in the participant's source documents.
4. Have a body weight in the range of 50 to 90 kg inclusive at screening. Have a body mass index (BMI) of 19 to 28 kg/m2 inclusive at screening.
5. Agree to abstain from alcohol intake 24 hours before administration of study drug, during the in-patient period of the study and 24 hours prior to all other ambulatory visits, up until and including the discharge visit.
6. Agree not to use prescription medications within 14 days prior to study drug administration and through the duration of the study, unless approved by the PI and Sponsor medical monitor.
7. Non-smokers or abstinence from tobacco or nicotine-containing products for at least 3 months prior to screening.
8. Agree not to use over-the-counter (OTC) medications \[including decongestants, antihistamines, and herbal medication (including herbal tea and St. John's Wort)\], within 14 days prior to study drug administration through the discharge visit, unless approved by the PI and Sponsor medical monitor. Occasional use of paracetamol at recommended doses is allowed. Special rules apply for aspirin, corticosteroids and nonsteroidal anti-inflammatory drugs (NSAIDS (see exclusion criteria 6-7-8-9)
9. Venous access (both arms) sufficient to allow blood sampling and study drug administration as per protocol.
10. Participants and their partners of childbearing potential \[meaning who are not surgically sterile (tubal ligation/obstruction or removal of ovaries or uterus) or post-menopausal (absence of menstrual periods for at least 12 consecutive months)\] must be willing to use 2 methods of contraception: - a highly effective method of birth control starting at screening. Highly effective methods of birth control are defined as those that result in a low failure rate (i.e. Pearl Index less than 1% per year) when used consistently and correctly, such as implants, rings, patches, injectable or combined oral contraceptives, intrauterine devices (IUDs), or sexual abstinence (periodic abstinence e.g. calendar, ovulation, symptothermal, postovulation methods, declaration of abstinence for the duration of the trial, and withdrawal are not acceptable methods of contraception) . - and a local barrier form of contraception. Acceptable barrier methods are either the participant's use of a condom or the partner's use of an occlusive cap or diaphragm, or spermicides. Participants will not donate sperm from the selection visit and up to 90 days after the infusion. In case of sterile or vasectomised participants, no contraception will be required for their partners of childbearing potential.
11. Willing/able to adhere to the study visit schedule and other requirements, prohibitions and restrictions specified in this protocol.
