About this study

Official title: A Phase Ia Clinical Study of HIV Entry Inhibitor CPT31: Single Ascending Dose Study of Safety, Tolerability, Immunogenicity, and Pharmacokinetics in Healthy Adults

This first-in-human study will evaluate the safety, tolerability, immunogenicity, and pharmacokinetics of the HIV entry inhibitor CPT31 (cholesterol-PIE12-2-trimer) in healthy adults. This is a randomized, placebo-controlled, double-blind, single ascending dose study.

Read the detailed description

This is a single subcutaneous (SC) dose study. Doses will be administered in an escalating manner following satisfactory review by a Protocol Safety Review Team (PSRT) of the safety, tolerability and pharmacokinetic (PK) data through Day 6 from the lower dose levels. 32 healthy subjects will be studied in 4 groups (Groups A1 to A4).

This study will comprise a placebo-controlled, double-blind, single-dose, sequential-group design in healthy subjects. Each subject will participate in 1 treatment period and reside in the Clinical Research Unit (CRU) from Day -1 through Day 6. It is planned for 6 subjects per dose level group to receive SC CPT31 and 2 subjects to receive matching placebo. Each group will be divided into 2 cohorts, with each cohort being dosed 72 hours apart. Sentinel dosing will take place in the first cohort, which will comprise 2 subjects, with 1 subject receiving CPT31 and 1 subject receiving placebo. The second cohort will comprise 6 subjects, with 5 subjects receiving CPT31 and 1 subject receiving placebo. Blood samples for PK analysis and assessment of immunogenicity will be collected predose and up to 5 days postdose, with an additional immunogenicity sample taken at the Follow-up visit.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing CPT31 in people with HIV Infections, run by Navigen, Inc. 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 5 inclusion and 19 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 21 Feb 2023. 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 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 21 Feb 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?

Adverse Events (time frame: Check-in (Day -1) through Follow-up (Day 28-30)). 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 21 Feb 2023.
