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.

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

  • Adult

Accepts Healthy Volunteers

  • Clinically significant major illness or undergone major surgery within 3 months prior to the trial;
  • Blood donation within 3 months, or plans to donate blood during this study, or transfusion or blood loss ≥200 mL within 4 weeks prior to the trial;

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
Correlation between HDM1002 Plasma Concentration and ΔΔQTc
Time Frame: From the base line ECG (Day -1) to end of the period, up to 48 hours post-dose
HDM1002 plasma concentration in ng/mL measured by validated LC-MS/MS; ΔΔQTc in msec derived from Fridericia-corrected QT interval with baseline and placebo correction, using 12-lead ECG read centrally in a blinded manner.
From the base line ECG (Day -1) to end of the period, up to 48 hours post-dose

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
Categorical outliers for QTc, HR, PR, and QRS
Time Frame: From the base line ECG (Day -1) to end of the period, up to 48 hours post-dose
QTc, PR, and QRS expressed as msec, HR expressed as beats per minute
From the base line ECG (Day -1) to end of the period, up to 48 hours post-dose
Incidence of adverse events (AEs) and serious adverse events (SAEs)
Time Frame: 25 days

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date.
