GLPG0492 Pharmacodynamics
GLPG0492 Pharmacodynamics
GLPG0492 is a selective androgen receptor modulator: the compound should help protect against
 (or help restore) muscle loss in case of immobilization (e.g. after orthopedic surgery) or
 due to aging (androgenic effect), but without anabolic effects (e.g. effect on testosterone).
 In the first part of the current study it will be tested whether GLPG0492 given orally to
 healthy male volunteers increases the protein synthesis in muscle, as measured by the uptake
 into the muscle of intravenously infused phenylalanine.

 In the second part of the study, the effect of the compound on the "hormone household" in
 healthy, postmenopausal women will be assessed.
Inclusion Criteria:

 -  Healthy male, age 18-50 years (for part 1), and postmenopausal subjects age 35-65
 years (for part 2)

 -  Body mass index (BMI) between 18-30 kg/m², inclusive.

 -  For men: normal values of testosterone (175-781 ng/dL) and LH (1.24-8.62 U/L).

 -  Women must be postmenopausal for at least 2 years with postmenopausal FSH level
 according to the local lab (+negative pregnancy test at screening & admission).

 Exclusion Criteria:

 -  smoking

 -  drug or alcohol abuse

 -  hypersensitivity to any of the ingredients of the study drug
