About this study

The purpose of this research study is to determine whether taking a one-time dose of a combination of putatively learning-enhancing medications can improve treatment response to a brief learning-based psychotherapy for public speaking anxiety. The two medications are (1) d-cycloserine (DCS), a medication that is an agonist (facilitator) of the NMDA glutamatergic receptor and has been shown in previous studies to facilitate some kinds of learning and memory; and (2) mifepristone, a medication that blocks cortisol, and in preclinical (animal) studies has been shown to reverse certain kinds of stress-related learning impairment or negative learning.

Specifically, the investigators goal is to determine if DCS and mifepristone taken together augment the learning that occurs during a brief psychotherapy session---a public speaking exposure exercise. Evidence for this learning effect would be a finding that participants have reduced anxiety at subsequent public speaking exposures.

Read the detailed description

The study has a total of 4 visits, and the medications are given as a one-time dose at only one visit (the second visit).

  1. During the first visit, a trained clinical interviewer will provide informed consent and conduct a structured clinical interview. Participants will be included if they are adult males diagnosed with social anxiety disorder and express a fear of public speaking, as well as approximately 10 healthy control participants. Eligible participants will be asked to complete self-report ratings of social anxiety and psychological symptoms and a standard interview about anxiety symptoms. The experimenter will conduct neuropsychological tests used to measure the participant's cognitive functioning.
  2. At the second visit the participant will be administered a one-time only dosage of both medications. The participant will be asked to prepare a speech within a short period of time, this is an example of exposure therapy. In exposure therapy, people are exposed to a situation they fear, such as public speaking, in a safe and controlled environment. Often when people do exposure therapy, they find that the situations they have been afraid of are not actually as scary as they seem. The exposure exercise in this study will consist of giving a speech while being video-recorded. Before the exposure exercise, participants will be provided with 250mg DCS and up to 1200mg of mifepristone. Participants will rate their anxiety level and negative and positive affect before and after the speech, as well as during the speech. The experimenter will again conduct neuropsychological tests used to measure the participant's cognitive functioning.
  3. (3) \& (4) During the next two visits, participants will complete a second and third public speaking exposure exercise identical to the first, with the exception that they will NOT receive medication. Participants will complete a similar battery of symptom measures and anxiety ratings. The investigators will look at a change in anxiety ratings and symptomatology between exposure session 1, exposure session 2, and exposure session 3.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Will measure medication tolerability and safety per participant report (i.e. few or no side effects severe enough to stop treatment)

    As measured by a self-reported side effects assessment conducted at this time point entitled: "Spontaneous Reports of Side Effects". This assessment will measure any reports of side effects as well as tolerability.

    Measured: End of Session 2--(7-10 days after Session 1)

Secondary outcomes (4)
  1. Improvements in Anxiety as measured by several Self Report Assessments

    Will measure CHANGES in anxiety level from 1st session to 2nd session as reported in the following self reports:

    Liebowitz Social Anxiety Scale (LSAS) Brief Resilient Coping Scale (BRCS) Post Event Processing Measure (PEP)-done at beginning of sessions 1, 3 and 4 (to reflect back on previous social engagements), and after speeches delivered at sessions 2, 3, and 4.

    Subjective Units of Distress Scale 0-100(SUDS 0-100) Social Interaction Anxiety Scale (SIAS) Social Phobia Scale (SPS) Subtle Avoidance Frequency Examination (SAFE) Positive and Negative Affect Scale (PANAS)

    Measured: Session 2- 1st exposure therapy session, occurs 7-10 days after Session 1

  2. Level of Anxiety as measured by several Self Report Assessments

    Will measure initial anxiety level at Session 1 as reported in the following self reports:

    Liebowitz Social Anxiety Scale (LSAS) Brief Resilient Coping Scale (BRCS) Social Interaction Anxiety Scale (SIAS) Social Phobia Scale (SPS) Subtle Avoidance Frequency Examination (SAFE) Positive and Negative Affect Scale (PANAS)

    Measured: Session 1- initial self reports collected;

  3. Improvements in Anxiety as measured by several Self Report Assessments

    Will measure CHANGES in anxiety level from 2nd session to 3rd session as reported in the following self reports:

    Liebowitz Social Anxiety Scale (LSAS) Brief Resilient Coping Scale (BRCS) Post Event Processing Measure (PEP)-done at beginning of sessions 1, 3 and 4 (to reflect back on previous social engagements), and after speeches delivered at sessions 2, 3, and 4.

    Social Interaction Anxiety Scale (SIAS) Social Phobia Scale (SPS) Subtle Avoidance Frequency Examination (SAFE) Positive and Negative Affect Scale (PANAS) Perception of Speech Performance (PSP)- done at beginning of sessions 3 and 4 (to reflect back on previous speech/ previous session), and after speeches delivered at sessions 2, 3, and 4.

    Subjective Units of Distress Scale 0-100(SUDS 0-100)

    Measured: Session 3- 2nd exposure therapy session- occurs 7- 10 days after Session 2

  4. Improvements in Anxiety as measured by several Self Report Assessments

    Will measure CHANGES in anxiety level from 3rd session to 4th session as reported in the following self reports:

    Liebowitz Social Anxiety Scale (LSAS) Brief Resilient Coping Scale (BRCS) Post Event Processing Measure (PEP)-done at beginning of sessions 1, 3 and 4 (to reflect back on previous social engagements), and after speeches delivered at sessions 2, 3, and 4.

    Social Interaction Anxiety Scale (SIAS) Social Phobia Scale (SPS) Subtle Avoidance Frequency Examination (SAFE) Positive and Negative Affect Scale (PANAS) Perception of Speech Performance (PSP)- done at beginning of sessions 3 and 4 (to reflect back on previous speech/ previous session), and after speeches delivered at sessions 2, 3, and 4.

    Subjective Units of Distress Scale 0-100(SUDS 0-100)

    Measured: Session 4- 3rd exposure therapy- occurs 3 months later

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: COVID and staffing issues). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Will measure medication tolerability and safety per participant report (i.e. few or no side effects severe enough to stop treatment) (time frame: End of Session 2--(7-10 days after Session 1)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
