Trial Outcomes & Findings for A Study of Multiple-ascending Doses of IW-3300 in Healthy Subjects (NCT NCT05362695)

NCT ID: NCT05362695

Last Updated: 2024-02-02

Results Overview

An adverse event (AE) is any untoward medical occurrence in a participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE was considered a treatment-emergent AE (TEAE) if the AE started after initial study drug administration and within 1 day of the last dose of study drug.

Participant Flow

The study was designed to include up to 3 cohorts with 9 participants per cohort. Within each cohort, participants were randomized to receive a single dose of IW-3300 (6 participants) or placebo (3 participants). Doses to be evaluated were 100 and 300 μg. An optional 3rd cohort was planned to test an IW-3300 dose of \>100 μg but \<300 μg. Based on a blinded review of safety and tolerability data from Cohorts 1 and 2, the Dose Escalation Committee decided not to enroll the optional 3rd Cohort.

As pre-specified by the statistical analysis plan, for the analyses reported herein, data from the 3 participants dosed with placebo in each of the 2 cohorts were pooled into a single placebo group (N=6).

PRIMARY outcome

Timeframe: From first dose of study drug through 24 hours post-Day 1 dose

Population: Safety Analysis Set (all participants who received any amount of study drug)

An adverse event (AE) is any untoward medical occurrence in a participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE was considered a treatment-emergent AE (TEAE) if the AE started after initial study drug administration and within 1 day of the last dose of study drug.

PRIMARY outcome

Timeframe: From first dose of study drug through 24 hours post-Day 1 dose

Population: Safety Analysis Set (all participants who received any amount of study drug)

A serious adverse event (SAE) is defined as any untoward medical occurrence that, at any dose: results in death; is lifethreatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent disability/incapacity; is a congenital anomaly/birth defect; or other situations such as important medical events that may not be immediately life threatening or result in death or hospitalization but may jeopardize the subject or may require medical or surgical intervention to prevent one of the other outcomes listed in the above definition. An SAE was considered a treatment-emergent SAE (serious TEAE) if the SAE started after initial study drug administration and within 1 day of the last dose of study drug.
