Eligibility Criteria
You may qualify if:
- years, both inclusive
- male and female
- Considered generally healthy upon completion of medical history and screening safety assessments, as judged by the Investigator.
- BMI \>18.5 and \<30.0 kg/m2
- HbA1c \<5.7 %
- Informed consent as documented by signature
You may not qualify if:
- Receipt of any medicinal product or nutritional product in clinical development within 30 days before enrollment in this trial.
- Any history or presence of clinically relevant comorbidity, as judged by the Investigator.
- Signs of acute illness as judged by the Investigator.
- Any serious systemic infectious disease during four weeks prior enrollment in this trial
- Clinically significant abnormal screening laboratory tests, as judged by the Investigator.
- AST and/or ALT \> 2 times the upper limit of normal.
- Elevated serum creatinine values above the upper limit of normal.
- Systolic blood pressure \< 90 mmHg or \>139 mmHg and/or diastolic blood pressure \< 50 mmHg or \>89 mmHg (excluding white-coat hypertension; therefore, a repeat test showing results within range will be acceptable).
- Heart rate at rest outside the range of 50-90 beats per minute.
- Clinically significant abnormal standard 12-lead electrocardiogram (ECG) after 5 minutes resting in supine position at screening, as judged by the Investigator.
- Significant history of alcoholism or drug abuse as judged by the Investigator consuming more than 24 grams alcohol/day (for males), 12 grams alcohol/day (for females) on average.
- Smoking or use of nicotine substitute products.
- Any medication (prescription and non-prescription drugs) within 14 days before screening.
- Blood donation or blood loss of more than 500 mL within the last 3 months prior to screening.
- Mental incapacity, unwillingness or language barriers precluding adequate understanding or co-operation.
- +25 more criteria
