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

This is a double-blind, randomized, placebo-controlled, ascending single dose and multiple dose escalation study of TT-00920 in healthy subjects. Each dosing cohort will comprise of 10 randomized subjects. Subjects received a single dose of TT-00920/ placebo during a single dose period, followed by a 3-10 day washout period, and then entered a 7-day multiple dose period, in which subjects received TT-00920/ placebo three times daily (TID) for days 1-6 and a single dose on day 7. The study will consist of a Screening Period, an In-house Period and a Follow-up.

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.

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
Percentage of Participants Who Experience at Least One Treatment-emergent Adverse Event (TEAE) as assessed by Investigator
Time Frame: 20 days
An Adverse Event (AE) is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. A TEAE is defined as an adverse event that occurred or worsened after receiving study drug.
20 days
Percentage of Participants With Clinically relevant changes in vital signs
Time Frame: 20 days
Vital signs include temperature, respiratory rate, blood pressure and pulse
20 days
Percentage of Participants With Clinically relevant changes in clinical laboratory tests
Time Frame: 20 days
Safety laboratory tests includes hematology, coagulation, serum chemistries, and urinalysis.
20 days
Percentage of Participants With Clinically relevant changes in Electrocardiogram (ECG)
Time Frame: 20 days
A standard 12-lead ECG was performed.
20 days

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.

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
