Ceftibuten/VNRX-7145 in Participants With Varying Degrees of Renal Function

VNRX-7145-103: A Phase 1, Open-label Study to Evaluate the Pharmacokinetics, Safety, and Tolerability of Ceftibuten/VNRX-7145 in Participants With Varying Degrees of Renal Function

This is an open-label, multicenter, parallel-group study in participants with normal renal function, mild, moderate, or severe renal impairment, or end stage renal disease (ESRD) undergoing standard intermittent dialysis. The pharmacokinetics (PK) of the inactive prodrug VNRX-7145, its active parent drug VNRX-5236, and ceftibuten will be evaluated after a single oral dose of ceftibuten/VNRX-7145.
