This is a Phase 1, non-randomized, parallel group, open-label study to characterize the effect of renal function on the PK of bevenopran in 1 or more study centers. At screening, eligible subjects will be enrolled and assigned to 1 of 5 parallel study groups of approximately 8 to 12 subjects each based on the classification of the renal function using estimated glomerular filtration rate (eGFR) from the Modification of Diet in Renal Disease (MDRD) Study, as presented in the FDA guidance on renal impairment studies. There are 5 study groups based on eGFRs.
