Primary outcomes

  1. Proportion of Patients Who Develop 2 or More Follicles With Diameter 16 mm or Larger

    Time frame: 8 months

    Proportion of patients who develop 2 or more follicles with diameter 16 mm or larger.

Secondary outcomes

  1. Pharmacokinetic Profille of BGS649 as Described by AUC0-672h

    Time frame: 8 hours

    AUC0-672 is a measurement of how much drug reaches a person's bloodstream in a given period of time after a dose is given. Measurements were performed at dose 1 (in cycle 2) and after dose 2 (in cycle 4). Sampling occured at pre-dose, 0.5-1.5h and 4-8 h post-dose.

  2. Pharmacokinetic Profile of BGS649 as Described by Cmax

    Time frame: 8 hours

    The peak plasma concentration of BGS649 after dosing at cycle 2 and cycle 4. Measurements were performed at dose 1 (in cycle 2) and after dose 2 (in cycle 4). Sampling occured at pre-dose, 0.5-1.5h and 4-8 h post-dose.

  3. Pharmacokinetic Profile of BGS649 as Described by Tmax

    Time frame: 8 hours

    Time taken to reach the maximum concentration in plasma of BGS649 at cycle 2 and cycle 4. Measurements were performed at dose 1 (in cycle 2) and after dose 2 (in cycle 4). Sampling occurred at pre-dose, 0.5-1.5h and 4-8 h post-dose.
