About this study

Official title: A Randomized, Placebo-Controlled, Phase I/II Trial of the Anti-HIV Activity and Safety of VGX-410 (Mifepristone) at Three Dose Levels in HIV-1 Infected Subjects

The purpose of this study is to determine the anti-HIV activity and safety of 3 different doses of mifepristone (also known as VGX-410 and RU486) in HIV infected people.

Hypothesis: Mifepristone will be generally safe (no serious adverse effects) and well tolerated.

Read the detailed description

Mifepristone is a potent anti-glucocorticoid compound that effectively inhibits replication of both laboratory and clinical HIV isolates in vitro. This study will evaluate the anti-HIV activity and safety of 3 different doses of mifepristone in HIV infected people.

This study will last approximately 2 months. Participants will be randomly assigned to one of 4 study arms, and will receive either mifepristone or placebo daily for 28 days. Arm A participants will receive one of three doses of placebo; Arm B participants will receive 75 mg mifepristone; Arm C participants will receive 150 mg mifepristone; and Arm D participants will receive 225 mg mifepristone. A thorough neck and thyroid examination will be performed within 30 days prior to study entry. Blood collection and vital signs measurement will occur at study entry and Days 3, 7, 14, 21, 28, and 56. Urine collection and pill counts will also be done at some study visits.

What is being measured

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

  1. Changes in HIV-1 viral load from baseline to Days 14 and 28

Secondary outcomes (7)
  1. Within 28 days on study, occurrence of toxicity, rash, and symptoms of adrenal insufficiency, including fatigue, nausea, anorexia, vomiting, and dizziness

  2. changes from baseline viral load on Days 7, 14, 21, 28, and 56

  3. pre-dose concentrations of mifepristone on Days 14 and 28 and serum level of alpha-1 acidic glycoprotein (AAG) at Day 0

  4. percentage and counts of CD4 and CD8 cells at baseline and on Days 14, 28, and 56

  5. Vpr amino acid sequences on Days 0, 14, 28, and 56

  6. comparison of the magnitude and diversity of effector T cell response to HIV antigens at Days 0, 28, and 56

  7. change in fasting concentrations of plasma insulin, free fatty acids, high-density lipoprotein (HDL) cholesterol and triglycerides, and in insulin sensitivity between Days 0 and 28

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Mifepristone in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 10 sites 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 6 inclusion and 23 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 1 Nov 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites 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 combined 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.

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?

Changes in HIV-1 viral load from baseline to Days 14 and 28. 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 NCT00099645, which also lists 3 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 1 Nov 2021.
