What researchers measure

Primary outcomes

  1. Change From Baseline in Worse Eye Intraocular Pressure (IOP) at Day 14

    Change from baseline in worse eye IOP at day 14. Worse eye IOP refers to the eye with the worse (highest) baseline IOP (a measurement of the fluid pressure inside the eye). A negative number change from baseline indicates a reduction in IOP (improvement).

    Time frame: Baseline, Day 14

Secondary outcomes

  1. Mean Concentration of AGN-207281 in Plasma at Day 7

    Mean concentration of AGN-207281 in plasma at day 7. Plasma is the liquid component of the blood in which the blood cells are suspended. On day 7, the plasma sample collected 15 minutes post-morning dose from each patient receiving AGN-207281 was analyzed to determine the average drug concentration levels of AGN-207281.

    Time frame: Day 7

  2. Mean Concentration of AGN-207281 in Plasma at Day 14

    Mean concentration of AGN-207281 in plasma at day 14. Plasma is the liquid component of the blood in which the blood cells are suspended. On day 14, the plasma sample collected 15 minutes post-morning dose from each patient receiving AGN-207281 was analyzed to determine the average drug concentration levels of AGN-207281.
