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
Measure Description
Time Frame
Change in pronunciation effect (subjective auditory assessment)
Time Frame: Baseline, 3 months, 6 months
Voice recordings judged by two independent evaluators, scored from 1-7, with lower scores meaning worse speech.
Baseline, 3 months, 6 months

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
Change in longest articulation time (continuous /a/, count)
Time Frame: Baseline, 3 months, 6 months
The longest duration time of one continuous / a / is recorded by a stopwatch, count and the average of three times are taken at the same time.
Baseline, 3 months, 6 months
Change in sound intensity (minimum / maximum / comfortable);
Time Frame: Baseline, 3 months, 6 months
Sound intensity of the minimum / maximum / comfortable loudness (measured 3 times per person) is recorded to calculate the dynamic range (in decibels)
Baseline, 3 months, 6 months
Change in total time required to read a text
Time Frame: Baseline, 3 months, 6 months
Standard Chinese text is read out loud, and the total time is recorded.
Baseline, 3 months, 6 months
Change in Voice Handicap Index
Time Frame: Baseline, 3 months, 6 months
Validated tool to assess Voice handicap. Statements on participant's voice quality and effect on social life are assessed by a five-point Likert-scale, ranged from 0-4, with high scores indicating more handicap (0 = Never, 4 = Always).
Baseline, 3 months, 6 months
Change in Quality of Life by SF-36
Time Frame: Baseline, 3 months, 6 months
Patient reported, 36-item, Score of calculated, ranging from 0-100, the lower the score the more disability. The higher the score the less disability
Baseline, 3 months, 6 months
Evaluation of operative performance
Time Frame: Baseline, 3 months, 6 months
Study-specific questionnaire on feasibility and satisfaction of clinicians
Baseline, 3 months, 6 months
Incidence of Adverse Events
Time Frame: Baseline, 3 months, 6 months
Any adverse events (including serious adverse events and device defect rates) will be recorded.
Baseline, 3 months, 6 months
