5. Body weight between 70 and 90 kg (both inclusive)

7. Considered generally healthy upon completion of medical history, physical examination, vital signs, ECG and analysis of laboratory safety variables, as judged by the Investigator.

1. Known or suspected hypersensitivity to IMP or related products.

2. Previous participation in this trial. Participation is defined as randomized.

3. Previous treatment with ZP4207.

4. Receipt of any medicinal product in clinical development within 3 months before randomization in this trial.

5. History of multiple and/or severe allergies to drugs or foods or a history of severe anaphylactic reaction.

6. Any history or presence of cancer except basal cell skin cancer or squamous cell skin cancer as judged by the Investigator.

11. Clinically significant abnormal standard 12-lead electrocardiogram (ECG) after 5 minutes resting in supine position at screening, as judged by the Investigator.

12. Significant history of alcoholism or drug abuse as judged by the Investigator or consuming more than 21 units of alcohol per week (one unit of alcohol equals about 250 mL of beer, one glass of wine of 120 mL, or 20 mL spirits).
