Study summary

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.

What researchers measure

Primary outcomes

  1. To evaluate the safety and tolerability of GLPG0492 in terms of adverse events, vital signs, ECG and abnormal lab tests in comparison with placebo

    Occurrence of adverse events, vital signs, ECG and abnormal lab tests as a measure of safety and tolerability

    Time frame: Up to 7 to 10 days after last treatment

  2. In male volunteers: effect on protein synthesis in muscle, as measured by the uptake into the muscle of intravenously infused phenylalanine

    During a 5-hour infusion of phenylalanine two muscle biopsies will be taken; this procedure is performed before and after one week of treatment with GLPG0492, to determine the effect of the compound.

    Time frame: One week

Secondary outcomes

  1. To determine the pharmacokinetic profile and metabolism after single and multiple oral doses of GLPG0492

    The plasma levels of GLPG0492 will be determined as a measure of pharmacokinetics, and the plasma and urine samples will be used for metabolism investigation

    Time frame: Up to 24h hours after last treatment

  2. In female volunteers: effects on hormone household.

    In female volunteers the effect of two weeks treatment on hormone levels in the blood will be assessed.

    Time frame: up to 7 to 10 days after treatment.
