March 23, 2022 updated by: Enterprise Therapeutics Ltd

A First in Human Randomised, Double Blind, Placebo-controlled, Two-part Study to Evaluate the Safety, Tolerability and Pharmacokinetics of Single and Multiple Ascending Doses (SAD and MAD) of Inhaled ETD001 in Healthy Male and Female Subjects

This is a first in human study of ETD001 a new drug being developed for the treatment of cystic fibrosis. The study is a randomised, placebo-controlled, double-blind interventional study to assess the safety, tolerability and pharmacokinetics of single and multiple ascending doses of inhaled ETD001in healthy male and female subjects.

Study Overview

Status

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Number of participants reporting one or more treatment emergent adverse event (TEAE)
Time Frame: Baseline to Week 8
Baseline to Week 8
Number of participants who discontinue due to an adverse event (AE)
Time Frame: Baseline to Week 8
Baseline to Week 8
Number of participants who meet the markedly abnormal criteria for 12-lead ECG assessment at least once post dose

Time Frame: Baseline to Week 8
Baseline to Week 8

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
