1. White male subjects aged 18 years to 45 years inclusive.
2. Body mass index between 20 kg/m2 and 28 kg/m2 inclusive, with a body weight of not less than 50 kg.
3. Subjects must be in good health as determined by medical history, physical examination, 12-lead ECG, oxygen saturation, vital signs, and clinical laboratory parameters.
4. Subjects willing to use barrier contraception (condom) during sexual intercourse with women, and no sexual intercourse with women who are pregnant or lactating is allowed from dosing of GRT6005 until 1 month after the Final Examination. Subjects willing to ensure that their female sexual partner uses medically acceptable contraception during this time frame (e.g., oral contraceptive).
5. Subjects giving written informed consent to participate in the trial.
1. Resting pulse rate is <45 bpm or >100 bpm after 5 min rest in semi-recumbent position.
2. Resting blood pressure after 5 min rest in semi-recumbent position:
a. Systolic blood pressure is <100 mmHg or >150 mmHg.
b. Diastolic blood pressure is <50 mmHg or >90 mmHg.
3. History of orthostatic hypotension. Standardization of trial population and safety.
4. Positive or missing test for human immunodeficiency virus antibodies (Type 1 and Type 2), hepatitis B surface antigens, hepatitis B core antigen antibodies, or hepatitis C virus antibodies.
5. Participation in another clinical trial within 90 days prior to enrollment into this trial.
6. Positive or missing drugs of abuse screening (alcohol breath test, urine screening test for drugs of abuse).
7. Diseases or condition known to interfere with the absorption, distribution, metabolism, or excretion of drugs.
8. Marked repolarization abnormality (e.g., suspected or definite congenital long QT syndrome with QT and/or QTcB >500 ms or prolonged QTcB, i.e., >450 ms).
9. Bronchial asthma or other respiratory diseases.
10. Definite or suspected history of drug allergy or hypersensitivity.
