A Single Dose-Escalation Study to Evaluate the Safety and Pharmacokinetics of Orally Administered DAA-I in Healthy Subjects (DAA-I)

January 24, 2016 updated by: Medicine, National University Hospital, Singapore
This is a placebo-controlled randomized phase 1 study to investigate the safety and pharmacokinetics of DAA-I in a cohort of healthy subjects.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.

Detailed Description

The study will be a single-blind, step-wise dose escalation, placebo controlled study in healthy subjects consisting of up to 3 dose steps of DAA-I. In the sequential step wise design, a single dose of DAA-I or placebo will be administered to 6 subjects for one treatment group. For each dose step, 4 subjects will receive DAA-I and 2 subjects will receive placebo. Subjects will be randomly allocated to one dose step. Step One would have to be completed before Step Two. Escalation up to Step Two and subsequent steps would depend on the safety results from the preceding step(s). There will be an interval of 6 hours between the dosing of the first and second DAA-I-treated volunteers of each cohort to allow for early cardiovascular monitoring. Only if there are no safety signals identify from these subjects as assessed by the Safety Review Committee can simultaneous dosing of the remaining volunteers be carried out.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

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.

Ages Eligible for Study

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
Measure Description
Time Frame
Evaluate the safety and dose range of DAA-I after single oral dose administration
Time Frame: 24 hours
Evaluate the safety (in terms of effect on normal blood pressure, pulse, and 12-lead ECG) of DAA-I following a single oral administration in 12 healthy subjects (0.08 mg/kg/subject in 4 subjects, 0.7 mg/kg/subject in 4 subjects, and 1.5 mg/kg/subject in 4 subjects).
24 hours

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.
Outcome Measure
Measure Description
Time Frame
Evaluate the pharmacokinetics of DAA-I after single oral dose administrations
Time Frame: 24 hours
Evaluate the plasma level of DAA-I in each subject at baseline (0 hr) and at 0.25, 0.5, 1, 2, 3, 4, 5, 6, and 12 hr after oral administration of a single-dose of DAA-I, and determine the area under the plasma concentration versus time curve (AUC).
