About this study

Official title: Longvida Curcumin Human Pharmacokinetics (PK) Study

The primary objective of the study is to characterize the curcumin metabolites of 2 different capsule formulations of curcumin relative to unformulated Curcuma longa extract of Rhizomes including assessing relative bioavailability and absorption/kinetic profile of curcumonoids and their metabolites in human plasma and urine after acute consumption.

Read the detailed description

This study is a randomized, 3-arm, double-blinded, within subject cross-over trial focused on understanding pharmacokinetic profile of curcuminoids and their metabolites after intake of curcumin supplement with different capsule formulations.

A planned sample size of 6 will be enrolled into the study. This study will require one initial screening visit and 3 weekly visits. This study will take approximately 4 weeks per subject to complete.

The initial screening visit will provide subject with the informed consent document and determine subject eligibility through anthropometric measurements, vital signs, fasting blood glucose test (finger prick), and completion of a survey relate to general eating, health, and exercise habits.

If willing and eligible to participate, subjects will be invited to participate in the study for 3 study days. Subjects will be instructed to maintain their usual diet pattern and physical activity throughout study duration.

Subject will arrive at the center in a fasted state for at least 10 hours, well hydrated and rested. Each study visit will require blood draws throughout the visit. After evaluation of subject's health status (via anthropometric, vital sign and blood glucose measurements and in-person interview), a Licensed health Care Professional will place a catheter in subject's arm for the purpose of multiple blood sample collections and take the initial blood draw in the fasting state. Subjects will be randomized to receive a curcumin supplement based on randomized treatment sequences for 3 study visits immediately after fasting blood draw. The sequences of receiving the supplement at each visit will be randomly assigned based on treatment sequences.

Each study visit will involve with blood samples collection at time points 0 (fasting), 0.5, 1, 2, 4, 6, and 8 hour (h) for assessment of change in plasma curcuminoids and metabolites. A standard breakfast will be provided immediately after the 0.5 h blood collection and standard lunch after 6 h blood collection. Urine samples will be collected at 0 (fasting), 4 and 8 h.

Questions about this trial

What is this clinical trial studying?

A study testing Treatment1, Treatment2 and Treatment3 in people with Healthy, run by Clinical Nutrition Research Center, Illinois Institute of Technology 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 21 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 8 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.

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 plasma curcumin metabolites among 3 different treatments (time frame: 8 hours Postprandial Study). 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 8 Feb 2023.
