About this study

The purpose of this voluntary research study is to determine if a dietary supplement containing a substance called protocatechuic acid (PCA) can change markers in blood related to immunity (a body's natural ability to fight diseases and infections) over a 14-day study period. Blood tests and other assessments will be completed before and after taking either 1,000 milligrams a day of protocatechuic acid (PCA) or a placebo (i.e., a sugar pill) for 14 days.

Read the detailed description

In this pilot study, the Investigator will utilize a double-blind placebo-controlled randomized design. Fifty (50) healthy men and women will be randomized into one of two arms: either agreeing to take placebo or 1000 mg PCA oral capsules daily. Study treatment will continue for 2 weeks (14 days).

At baseline and end of 2 weeks treatment period, various clinical and laboratory measurements will be performed. Vital signs, a 2-chair test, and personal health assessment will be measured, and blood will be drawn. The following endpoints will be evaluated in blood: erythrocyte sedimentation rate (ESR), high sensitivity C-reactive protein (hsCRP), C-X-C motif chemokine ligand 9 (CXCL9), 25-hydroxy vitamin D.

Model description
We will assign subjects to the placebo or PCA supplementation randomly using Statistical Analysis System (SAS) software that contains a random assignment generator. It will output 50 assignments, equal to the number of subjects that we expect to enroll. Subjects will be assigned to one of the groups in a prospective manner as they are recruited throughout the study period.

Questions about this trial

What is this clinical trial studying?

A study testing Protocatechuic Acid or PCA in people with Immunity, run by Milton S. Hershey Medical Center 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 7 inclusion and 5 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The record says: withdrawn, as of the sponsor's last update on 29 Mar 2024. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

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?

Erythrocyte Sedimentation Rate (time frame: Baseline and end of 2 weeks). 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?
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 29 Mar 2024.
