  2. Body Mass Index (BMI) between 19 and 33 kg/m2 (relates to a body mass within 15% of ideal body mass for height and age).
  3. Body mass not less than 50 kg.
  4. Medical history, vital signs, physical examination, standard 12-lead electrocardiogram (ECG) and laboratory investigations must be clinically acceptable or within laboratory reference ranges for the relevant laboratory tests, unless the investigator considers the deviation to be irrelevant for the purpose of the study.
  5. Non-smoker or mild to moderate smoker (≤ 10 cigarettes daily).
  6. Females, if:

    • Serum follicle-stimulating hormone (FSH) ≥ 25.8 mIU/mL AND a serum estradiol level of ≤ 54.7 pg/mL at screening.
    • Not of childbearing potential, e.g., has been surgically sterilized, undergone a hysterectomy, amenorrhea for ≥ 12 months and considered post-menopausal.

    Note: In postmenopausal women, the value of the serum pregnancy test may be slightly increased, but if not increasing upon repeat, the female will be included in the study.

    • Not on thyroid hormone replacement therapy or on stable thyroid hormone replacement therapy for at least 3 months before the first administration of IMP.

    Not on statin therapy or on stable statin therapy for at least 3 months before the first administration of IMP.

    Note: Treatment with calcium channel blockers is NOT allowed.

  7. Written consent given for participation in the study. -

Exclusion Criteria:

  1. Evidence of psychiatric disorder, antagonistic personality, poor motivation, emotional or intellectual problems likely to limit the validity of consent to participate in the study or limit the ability to comply with protocol requirements.

  3. History of regular exposure to substances of abuse (other than alcohol) within the past year.
  4. Use of any medication, prescribed or over-the-counter or herbal remedies, within 2 weeks prior to the first administration of IMP, except for medication allowed per inclusion criteria (Section 7.3.1) or if the medication will not affect the outcome of the study in the opinion of the investigator.
  5. Female hormone replacement therapy (or other medicine containing estrogen, including health food products for menopausal symptoms, as these may contain natural estrogens), within 2 weeks prior to the first administration of IMP.
  6. Participation in another study with an experimental drug, where the last administration of the previous IMP was within 8 weeks before the first administration of IMP in this study.
  7. Donation or loss of blood equal to or exceeding 500 mL during the 8 weeks before the first administration of IMP.
  8. Treatment within the previous 3 months before the first administration of IMP with any drug with a well-defined potential for adversely affecting a major organ or system.
  9. A major illness during the 3 months before commencement of the screening period.
  10. History of hypersensitivity or allergy to the IMP or its excipients or any related medication.
  11. History of bronchial asthma or any other bronchospastic disease within the past 5 years.
