About this study

The purpose of this study is to determine how safe, effective, and well tolerated a new investigational antifungal drug, SUBA-itraconazole, is for patients who have been previously treated with fluconazole and have had either an insufficient response to treatment with fluconazole or a negative reaction to fluconazole preventing their further treatment with it.

Read the detailed description

This is a prospective, multi-center, open-label study involving subjects with proven or probable coccidioidomycosis refractory to fluconazole therapy following >40 days of treatment or subjects with proven or probable coccidioidomycosis who are intolerant to fluconazole.

The availability "Super Bioavailability" (SUBA) itraconazole 65 mg capsules with twice-daily dosing options with improved pharmacokinetics and lack of food or acidity requirements offers a substantial opportunity to improve the treatment of subjects with coccidioidomycosis.

What is being measured

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

  1. 1. The Proportion of Participants Who Achieve Clinical Improvement, in All Participants Who Took at Least One Dose of Study Drug

    Clinical Improvement is defined as at a) at least a 50% reduction in coccidioidomycosis Mycoses Study Group (MSG Score) from baseline value, or b) the unequivocal documentation of clinical improvement as recorded on the progress note of the medical provider, or c) a 25%-49% decrease in the MSG score from baseline value and a physician's impression of improvement as recorded on the progress note. The MSG score is a composite scoring system that has been used in numerous past studies of coccidioidomycosis. This system comprises the sum of points assigned based on the findings of: (1) clinical assessments, (2) radiographic imaging, and (3) serologic assays, with a lower score indicating better health.

    Measured: 180 days

Secondary outcomes (7)
  1. Number of Participants with Treatment-Emergent Adverse Events

    Treatment-emergent adverse events are defined as new events that occur following subject entry into the study or events that worsen following study entry state. Severity grading will be based on Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0. This is a descriptive scoring system which can be used for Adverse Event (AE) reporting. A grading (severity) scale is provided for each AE term as follows: Grade 1 = Mild AE; Grade 2 = Moderate AE; Grade 3 = Severe AE; Grade 4 = Life-threatening or disabling AE; Grade 5 = Death related to AE.

    Measured: 180 days

  2. Number of Participants with Abnormal Laboratory Evaluations of Safety

    Abnormal is defined as at least a 1 grade shift from baseline. Severity grading will be based on Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0. This is a descriptive scoring system which can be used for Adverse Event (AE) reporting. A grading (severity) scale is provided for each AE term as follows: Grade 1 = Mild AE; Grade 2 = Moderate AE; Grade 3 = Severe AE; Grade 4 = Life-threatening or disabling AE; Grade 5 = Death related to AE.

    Measured: 180 days

  3. Number of Participant Discontinuations of Therapy Due to Treatment-Emergent Adverse Events and/or Laboratory Evaluations of Safety

    Number of Participant Discontinuations of Therapy Due to Treatment-Emergent Adverse Events and/or Laboratory Evaluations of Safety

    Measured: 180 days

  4. Number of Participants with Any Interruptions of Therapy due to Treatment-Emergent Adverse Events and/or Abnormal Laboratory Evaluations of Safety

    Number of Participants with Any Interruptions of Therapy due to Treatment-Emergent Adverse Events and/or Abnormal Laboratory Evaluations of Safety

    Measured: 180 days

  5. Number of Participants with Interruptions of Therapy 7 Days or More in Duration due to Treatment-Emergent Adverse Events and/or Abnormal Laboratory Evaluations of Safety

    Number of Participants with Interruptions of Therapy 7 Days or More in Duration due to Treatment-Emergent Adverse Events and/or Abnormal Laboratory Evaluations of Safety

    Measured: 180 days

  6. Mean, Median, and Quartile Score Values for Mental Component Summary and Physical Component Summary Scores of the SF-12v2 Survey

    The Short Form 12 Question Health Survey, version 2 (SF-12v2) is a 12-question multipurpose survey instrument derived from the larger, Short Form 36 Question Survey. The SF-12v2 is to help determine the participant's overall state of wellbeing and health-related quality of life by means of assessing both physical and mental status at the time of the survey. The 8 domains of the survey are: physical functioning (PF), role-physical (RP), bodily pain (BP), general health (GH), vitality (VT), social functioning (SF), role- emotional (RE), and mental health (MH). Mental and physical composite scores (MCS \& PCS) are computed using the scores of twelve questions. MCS and PCS values can range from 0 to 100, where a higher score indicates better health.

    Measured: 42 days

  7. Mean, Median, and Quartile Score Values for Mental Component Summary and Physical Component Summary Scores of the SF-12v2 Survey

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing SUBA-itraconazole in people with Coccidioidomycosis and Valley Fever, run by George R Thompson at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 18 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 19 Jul 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 withdrawn before enrolling participants, so there are no results.

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?

1. The Proportion of Participants Who Achieve Clinical Improvement, in All Participants Who Took at Least One Dose of Study Drug (time frame: 180 days). 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.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Jul 2021.
