About this study

Official title: Vaginal Prednisone Administration for Prevention of Adrenal Crisis - a Bioequivalence Study

Patients with chronic adrenal insufficiency need to adapt their glucocorticoid replacement dose in conditions of physical or psychological stress to prevent life threatening adrenal crisis. In cases of more severe impairment or unsecure gastrointestinal absorption (e.g. gastroenteritis, severe infectious disease), rapid and highly dosed administration of glucocorticoids is crucial. The study is conducted to offer female patients the possibility to perform efficient prednisone self-administration in emergency situations in a way of administration, which is easy to perform and accepted by the patients. Therefore, pharmacokinetics and safety of vaginal prednisone administration will be studied and compared to rectal administration.

Read the detailed description

As patients with adrenal insufficiency still die from adrenal crisis, improvement of both prevention and also emergency management is needed. It is clear that perfect equipment and education of patients is key for further crisis prevention and management. Vaginal administration of prednisone-suppositories is easy to perform and independent of the gastro-intestinal system. Thus, this study aims at the efficacy, feasibility and safety of vaginal administration of prednisone-suppositories.

Recruitment:

Patients with primary adrenal insufficiency will be recruited. The adrenal insufficiency registry of Würzburg comprises more than 150 patients with primary adrenal insufficiency. Several patients have already indicated their interest to participate in the study. According to the European Medicines Agency (EMA) notes for guidance on the investigation of bioavailability and bioequivalence the number of 12 participants is regarded as the minimum required number.

Trial flow:

Pharmacokinetic studies will be performed at two different study visits. Patients will receive a 100mg prednisone suppository (Rectodelt® 100 mg) vaginal and rectal on two different study visits (interval longer then one week). Blood samples for determination of prednisone and adrenocorticotropic Hormone (ACTH) levels will be collected over a time period of 6 hours. Patients receive a diary to document eventual local or systemic adverse events during the following 7 days.

Stopping rules:

Participation of patients is fully voluntarily. Patients are able to stop participation in the study at any point in time. In addition, patients might claim the elimination of all data material at any point in time. Furthermore, study participation will be stopped for the individual patient, if new safety issues occur (e. g. new diagnosis of Diabetes mellitus, pregnancy or acute infectious disease) during the study. Relevant risks to the patients are highly unlikely. However, if 2 or more patients experience serious adverse events associated with the vaginal administration of prednisone with high likelihood, the study will be stopped.

Written informed consent:

A consent document including patient information upon the nature, scope and possible consequence of the trial must have been approved by the Institutional Review Board. Patients amenable for inclusion in the trial will be given sufficient time to study the written information, as well as possibility to ask questions before signing the consent document.

Analysis:

Documentation and analysis will be performed at the Department of Medicine I, Endocrine and Diabetes Unit, University of Würzburg, Germany. Data will be documented after pseudonymisation in a data base. Data analysis is mainly descriptive (bioequivalence of vaginal prednisone administration compared to rectal application, estimation of the patients regarding convenience and tolerability of different modes of drug administration, safety aspects).

Safety:

In the course of the trial, changes in physical findings as well as clinical signs and symptoms that may reflect adverse effects will be documented. Furthermore, all adverse events will be documented on the appropriate report form. When an adverse event occurs it will be graded according to the National cancer Institute - common toxicity criteria (NCI-CTC) (version 4.0). Patients receive a diary to document any local or systemic adverse event during the following 7 days after intervention. In addition, patients will be contacted by phone 3(±1) and 7(±1) days after vaginal administration of prednisone. If patients report any adverse events that are possibly related to the vaginal administration route, they will be called-in for further physical examination and detailed documentation. To further enhance individual patient's safety during the study, a safety assessment will be performed prior to the subsequent intervention. In addition, a safety assessment will be performed after 4 and 8 subsequent vaginal administrations of prednisone with evaluation of events during the 7 day follow up period after administration.

What is being measured

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

  1. Bioequivalence of vaginal prednisone administration compared to rectal application, assessed by repeated determination of prednisolon levels (in blood)

    The hypothesis is that the same prednisolone levels can be achieved within the same time frame after vaginale administration compared to rectal application.

    Measured: up to 12 months

Secondary outcomes (3)
  1. Safety of the vaginal administration of prednisone compared to rectal application, assessed by the number of participants with treatment-related adverse events (using the NCI-CTC, version 4.0).

    Measured: up to 12 months

  2. Suppressive effects on ACTH levels after vaginal administration of prednisone compared to rectal application, assessed by repeated determination of ACTH-levels

    ACTH-levels are measured in plasma

    Measured: up to 1 week

  3. Tolerability by the patients assessed by a questionnaire

    Questions record the preference of the patients between vaginal and rectal application.

    Measured: up to 1 month

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing 100mg prednisone suppository in people with Adrenal Insufficiency, run by Wuerzburg University Hospital.

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 6 inclusion and 8 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: finished, as of the sponsor's last update on 20 Jun 2017. Status can change between updates, so confirm with the study contact before making plans.

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Bioequivalence of vaginal prednisone administration compared to rectal application, assessed by repeated determination of prednisolon levels (in blood) (time frame: up to 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02689960, which also lists 7 linked publications.

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 20 Jun 2017.
