Pharmacokinetics and Safety of Vilaprisan in Renal Impairment

Phase 1

Completed

• Conditions: Uterine Fibroids; Endometriosis
• Interventions: Drug: Vilaprisan (BAY1002670)

• Registration Number: NCT03411980
• Lead Sponsor: Bayer

Brief Summary

The purpose of the study is to evaluate the pharmacokinetics of vilaprisan in subjects with moderate to severe renal impairment compared with matched subjects with normal renal function.

Detailed Description

This is a multiple-center, open-label, non-randomized, single-dose study in 3 parallel groups of subjects with moderately or severely impaired renal function or normal renal function matched with regard to sex, age, race and weight. PK blood and urine sampling for determination of vilaprisan concentrations in plasma and urine, respectively, will be preformed at pre-defined time points up to 14 days post-dose. Safety and tolerability will be assessed through adverse events, clinical laboratory tests, vital signs, 12-lead electrocardiograms and physical examinations.

Inclusion Criteria

• BMI: 18 to 40 kg/m*2 (inclusive)
• Decreased renal function, as assessed at screening, based on serum creatinine and calculated according to the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula, either:

Moderately impaired renal function: eGFR: 30 to 59 mL/min/1.73 m*2; or Severely impaired renal function: eGFR <30 mL/min/1.73 m*2 but not on dialysis
