Official title
A Phase 1b, Open-label Trial to Assess the Safety, Pharmacokinetics, and Pharmacodynamics of NDI-5001 in a Capsule Following Daily Oral Doses to Adult Males With X-linked Congenital Nephrogenic Diabetes Insipidus
Overview
The primary purpose of this trial is to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of NDI-5001 administered as a capsule following daily oral dosing in adult males with X-linked congenital nephrogenic diabetes insipidus (NDI) due to vasopressin receptor Type 2 (V2R) mutations.
