Participant Flow

In Part 1, adults with moderate renal impairment (RI; determined by estimated glomerular filtration rate \[eGFR\]), and healthy participants, were recruited at 2 sites in the US. Part 2 was intended to enroll severe RI participants but was not conducted based on results of a planned interim analysis of Part 1 data.
