About this study

Official title: Kaempferol Absorption and Pharmacokinetics Evaluation (K.A.P.E.)

This study is a multi-site clinical trial designed to evaluate how the body absorbs and processes Kaempferol, a naturally occurring compound found in many plant-based foods. The primary purpose of the study is to measure the pharmacokinetics and biological absorption of Kaempferol in healthy adults.

Participants will receive Kaempferol and undergo scheduled blood and urine collections over a short study period. These samples will be used to measure Kaempferol levels in the body and to assess safety and tolerability. In addition, selected biological samples will be analyzed to explore molecular changes associated with Kaempferol exposure using advanced laboratory methods.

The study will be conducted at multiple research centers in the United States using a standardized protocol to ensure consistency across sites. The information collected will help improve understanding of how Kaempferol is absorbed and metabolized in humans and will support future research and regulatory evaluation.

Read the detailed description

This multi-site interventional study evaluates the pharmacokinetics and biological absorption of Kaempferol (KMP) in a U.S. population and is designed to generate human data to inform regulatory and translational planning for Kaempferol.

Kaempferol is a diet-derived flavonoid present in plant-based foods and dietary supplements. Existing evidence supporting biological activity has largely been derived from in vitro and animal studies, with limited human clinical data describing absorption, metabolism, and excretion. Preliminary nonclinical data support measurable biological activity following oral administration, including changes consistent with altered metabolic and mitochondrial function. Prior small human studies suggest tolerability but have not provided comprehensive pharmacokinetic characterization or integrated molecular profiling. The current study is intended to address these gaps using standardized procedures across multiple U.S. clinical research sites.

Participants receive oral Kaempferol administered under controlled study conditions and complete a defined schedule of clinic visits with serial biospecimen collections. Biospecimens are processed using harmonized standard operating procedures at collection sites, with centralized laboratory analyses used to reduce variability and improve data quality. Research data are maintained using coded identifiers and stored in secure systems consistent with institutional data protection requirements.

Primary endpoint: The primary endpoint is characterization of the pharmacokinetic profile of Kaempferol, including assessment of absorption, distribution, metabolism, and excretion using serial Kaempferol and metabolite measurements in blood and urine across predefined time points.

Secondary endpoints: Secondary endpoints include exploratory assessment of biological responses associated with Kaempferol exposure using multi-omics profiling (including genomics, transcriptomics, miRNA profiling, metabolomics, lipidomics, and proteomics). Secondary analyses also include integration of molecular profiling results with participant self-reported medical history using computational approaches to explore patterns associated with Kaempferol exposure and inter-individual variability in biological response. Additional secondary endpoints include evaluation of mechanistic and functional biomarker changes associated with oxidative stress, inflammation, and metabolic health in relation to Kaempferol intake.

Safety endpoints: Safety is assessed throughout the study period. Primary safety endpoints include the incidence and characterization of adverse events (AEs) and serious adverse events (SAEs), and tolerability based on participant-reported symptoms and clinical assessments. Secondary safety endpoints include clinical laboratory evaluations, including complete blood count testing, to identify potential safety signals associated with Kaempferol administration.

All study activities are conducted under institutional review board oversight. Written informed consent is obtained prior to initiation of study procedures. A limited waiver of documentation of consent may be used only for specific preparatory dietary instructions when approved by the IRB and when required by scheduling and protocol timing. Participant confidentiality is maintained through coding of data, restricted access to identifiable information, and secure storage of study records.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • KaempferolDietary supplement

    Kaempferol (KMP) is administered orally as encapsulated doses once daily for 8 consecutive days in healthy adult participants under controlled dietary conditions. This intervention is designed specifically for intensive pharmacokinetic characterization and biological absorption assessment, incorporating high-frequency serial blood and urine sampling across multiple time points. In contrast to typical dietary supplement studies, this intervention integrates comprehensive multi-omics profiling (including transcriptomics, miRNA-seq, metabolomics, lipidomics, proteomics, and genomic analyses) to evaluate mechanistic and functional biological responses to Kaempferol exposure. Safety and tolerability are monitored throughout the intervention period.

    Measured: From dosing on Day 1 through 24 hours after the final dose (Day 8)

  3. Area under the plasma concentration-time curve (AUC) of Kaempferol

    The area under the plasma concentration-time curve of Kaempferol, calculated using noncompartmental methods to quantify overall systemic exposure following oral administration.

    Measured: From dosing on Day 1 through 24 hours after the final dose (Day 8)

  4. Plasma elimination half-life (t½) of Kaempferol

    The terminal elimination half-life of Kaempferol in plasma, estimated from the terminal phase of the concentration-time curve following oral administration.

    Measured: From dosing on Day 1 through 24 hours after the final dose (Day 8)

  5. Apparent clearance of Kaempferol

Individual data sharing
No: Individual participant data (IPD) will not be shared because the study includes intensive pharmacokinetic and high-dimensional multi-omics data that could increase the risk of participant re-identification, even after de-identification. In addition, data sharing is subject to institutional policies, IRB restrictions, and data governance agreements that limit external distribution of individual-level data. Aggregate results and analyses will be disseminated through peer-reviewed publications and scientific presentations.
