A Pilot Study Investigating Bioequivalence Between a Single Dose of Formulation 2 and Formulation 3 of MEDI0382

1. Healthy subjects age 18 through 45 years at the time of screening.
2. Provision of signed and dated written informed consent prior to study-specific procedures.
3. Body mass index between 19 and 30 kg/m2 (inclusive) at screening
4. Good general health as judged by the investigator, based on medical history, physical examination including 12-lead ECG, vital signs, and blood and urinary laboratory assessments.
5. Female subjects of childbearing potential must have a negative pregnancy test at screening and randomization and must not be lactating.
6. Females of childbearing potential who are sexually active with a nonsterilized male partner must use at least one highly effective method of contraception (see Section 10.2 for definition of females of childbearing potential and for a description of highly effective methods of contraception) from screening and must agree to continue using such precautions through to the end of the study. It is strongly recommended for the male partner of a female subject to also use a male condom plus spermicide throughout this period. Cessation of contraception after this point should be discussed with a responsible physician. Periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of contraception.

Exclusion Criteria:

2. Impaired renal function, defined as s-creatinine ≥ 130 µmol/L
3. Estimated glomerular filtration rate (eGFR) \< 60 mL/min/1.73 m2
4. Blood pressure and heart rate in supine position outside the ranges of 90-140 mmHg systolic, 50-90 mmHg diastolic and heart rate 40-100 beats/min following a 10-minute rest period.
5. Any clinically significant abnormal ECG, as judged by the investigator
6. Active hepatitis B, measured by positive tests of surface antigen HBsAg and/or active hepatitis C, measured by positive hepatitis C virus antibody tests
7. Positive human immunodeficiency virus antibodies
8. Known or suspected allergy to MEDI0382, any component of the formulation, or related products

10. History of alcoholism or drug abuse during the last 12 months
11. Smoking of cigarettes or other tobacco products
12. Habitual excessive consumption of methylxanthine-containing (theophylline, caffeine or theobromine) beverages and foods (coffee, tea, soft drinks such as red bull, cola, chocolate) as judged by the investigator
13. Blood donation within the last 3 months
14. Participation in any other trial investigating other products or involving blood sampling within the past 30 days
