Trial Outcomes & Findings for Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of NBI-74788 in Adults With Congenital Adrenal Hyperplasia (NCT NCT03525886)

NCT ID: NCT03525886

Last Updated: 2022-05-03

Results Overview

Percent changes in 17-OHP were assessed through the collection of samples from 0600 hours to 1000 hours both prior to study drug administration (i.e., at baseline) and after 14 days of study drug dosing. The 3 samples collected during this morning window at each visit were averaged and used to determine the percent change from baseline.

Participant Flow

The study followed a sequential cohort design with four NBI-74788 dosing regimens, each administered for 14 consecutive days. There was \~2-week period to evaluate safety and tolerability data before proceeding from Cohort 1 to Cohort 2. Subjects who previously completed the study in Cohort 1 or 2 (and had no safety concerns) could reenroll into Cohorts 3 and/or 4 (in addition to new subjects); 18 unique subjects participated. First subject enrolled: 4/10/2018; Last subject completed: 4/7/2020

PRIMARY outcome

Timeframe: Baseline and Day 14

Population: Pharmacodynamic (PD) analysis set, which includes all enrolled participants who received at least one dose of study drug and have at least one PD parameter measurement at baseline and at least one PD parameter measurement at the Day 14 visit.

Percent changes in 17-OHP were assessed through the collection of samples from 0600 hours to 1000 hours both prior to study drug administration (i.e., at baseline) and after 14 days of study drug dosing. The 3 samples collected during this morning window at each visit were averaged and used to determine the percent change from baseline.
