About this study

Official title: A Phase 1 Safety and Pharmacokinetic Study of PC-1005 (MIV-150/Zinc Acetate/Carrageenan Gel) Administered Rectally to HIV-1 Seronegative Adults

The purpose of this study is to evaluate the safety and pharmacokinetics of PC-1005 gel when used as a rectal microbicide in HIV-uninfected men and women (cis or transgender) with a history of consensual receptive anal intercourse.

Read the detailed description

PC-1005 is a multipurpose prevention technology (MPT) microbicide in development that is active against HIV, HPV, and HSV-2. This study will evaluate the safety and pharmacokinetics of PC-1005 gel when administered rectally.

The study will enroll HIV-uninfected men and women (cis or transgender) with a history of consensual receptive anal intercourse. All participants will receive 3 single escalating doses of rectally administered PC-1005: 4 mL, 16 mL and 32 mL.

The study includes a total of 9 clinic visits and 1 follow-up contact by phone or in person. Participants will receive doses of PC-1005 at Visits 3, 5, and 7. A 2-to-6 week washout period will follow each dosing visit. If no adverse events that preclude continuation to the next dose are identified during this period, participants will receive the next scheduled dose of PC-1005. Participation in this study will last approximately 3 to 5 months.

Study visits will include physical examinations, throat swabs, behavioral assessments and interviews, and collection of blood, urine, rectal tissue, and cervical, vaginal, and rectal fluid.

    Response for "Overall, how did it feel to have the gel inside you?" at exit self-interview questionnaire.

    Measured: Through study completion, approximately 3-5 months for each participant

  3. Participant Self-report Gel Acceptability - Problems With Gel Use

    Responses for questions related to problem with gel use at exit self-interview questionnaire

    Measured: Through study completion, approximately 3-5 months for each participant

  4. Participant Self-report Gel Acceptability - Gel Acceptability

    Response for questions related to gel acceptability at exit self-interview questionnaire.

    Measured: Through study completion, approximately 3-5 months for each participant

  5. MIV-150 Concentrations in Vaginal Fluid

    Descriptive statistics such as the mean and median and corresponding 95% confidence intervals will be used to describe the MIV-150 concentrations in all biological matrices assessed at all scheduled time points

    Measured: Measured through participants' last study visit which will occur at Month 3 to 5, depending on the participant

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing PC-1005 gel in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 2 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 15 inclusion and 32 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 14 Apr 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 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 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?

Yes. Results are posted in the registry (first posted 14 Apr 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Frequency of Grade 2 or Higher Adverse Events (AEs) (time frame: Measured through participants' last study visit which will occur at Month 3 to 5, depending on the participant). The study lists 4 primary outcomes in all. 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 NCT03408899, which also lists 1 linked publication.

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 14 Apr 2023.
