The SAD part of the study comprised 16 healthier male subjects in 2 alternating cohorts (A and B, n = eight each and every). Cohort A received GLPG1205 ten, 90, 400, and 800 mg or matching placebo, and cohort B received GLPG1205 30, 200, and 600 mg or matching placebo. Subjects had been randomly assigned to acquire GLPG1205 or matching placebo within a three:1 ratio once in the beginning in the study. Moreover, subjects in cohorts A and B have been randomized to a remedy sequence. Each topic, in either cohort A or cohort B, had an enforced interval of at the very least 6 days between dosages. An interval of at the least three days was enforced between 2 dose levels (between cohort A and B). Subjects have been kept in-house in the evening of day to 26 hours immediately after dosing (morning of day two). Inside the MAD part of study 1, 24 healthful male subjects in three cohorts (C, D, and E; n = 8 each and every) each and every received GLPG1205 or matching placebo after day-to-day for 14 days. Cohorts C, D, and E received GLPG1205 50 mg when everyday or matching placebo, GLPG1205 100 mg when daily or matching placebo, and GLPG1205 200 mg once day-to-day or matching placebo, respectively. Inside a cohort, subjects have been randomized to acquire GLPG1205 or matching placebo inside a three:1 ratio. An interval of at least six days was enforced amongst cohorts. Subjects had been kept in-house from the evening of day until 26 hours following very first dosing (morning of day two), and from the evening of day 13 for the morning of day 15. Administration in the study drug was performed day-to-day in the clinical pharmacology unit. Study two. For the duration of study two, GLPG1205 50 mg or matching placebo was administered as capsules inside the morning 30 minutes just after the begin of a standard breakfast. Subjects were kept in-house from the evening of day to 26 hours following the very first dose (day two), and in the evening of day 13 until day 15. Administration from the study drug was performed everyday in the clinical pharmacology unit. Subjects returned to get a follow-up visit at day 35. In component 1, 24 healthy male subjects were matched into three cohorts CDC Inhibitor drug depending on body weight: Cohort A comprised 8 subjects aged 654 years, inclusive; cohort B comprised eight subjects aged 75 years (1:1 weight matched with cohort A subjects [5 kg]); and cohort C comprised eight subjects aged 18 to 50 years, inclusive (1:1 weight matched with cohort A subjects [5 kg]). All cohorts received GLPG1205 50 mg after daily or matching placebo, within a three:1 ratio, for 14 days. Inside the open-label second part of study two, eight subjects (cohort D) aged 65 to 74 years, inclusive, have been includedFigure 1.
