Pilot Trial of Fisetin in Healthy Volunteers and Older Patients With Multimorbidity

Status Not yet recruiting

Clinical Trial Summary

The accumulation of senescent cells with age is a central mechanism that contributes to the development of chronic diseases, primarily by driving systemic chronic inflammation. Senolytic compounds such as fisetin can selectively target senescent cells for elimination and reduce multiple age-related pathologies in animal models.

We will conduct a clinical trial in healthy volunteers and older patients with multiple chronic diseases. The participants will receive fisetin or placebo for two days, after which they will be examined at regular intervals for up to three months. We will investigate how fisetin is absorbed and metabolized by the body, and whether fisetin is safe. We will also identify methods to best measure the effect of fisetin on chronic inflammation, senescent cells, and general health.

Clinical Trial Description

The goal of this pilot trial is to conduct a controlled clinical study to gather data on the pharmacokinetic profile of fisetin and its metabolites and on the safety and tolerability of fisetin in healthy volunteers as well as in older medical patients. Furthermore, we aim to identify potential outcome measures and perform sample size calculations for these outcomes, with the intent to conduct a larger scale effect study, at later date, given the result from this pilot study suggests that this would be feasible and safe.

The trial consists of:

• a single-arm open-label study, in which healthy volunteers (n=20) will receive fisetin corresponding to 20 mg/kg/day for two consecutive days.

• a 2-arm triple-blind randomized placebo-controlled study, in which older medical patients (n=40) will receive either:

• 20 mg/kg/day fisetin for two consecutive days, or

• placebo for two consecutive days.

Each of the studies (open-label study and randomized placebo-controlled study) consists of three sub-studies:

• Sub-study I aims to investigate the pharmacokinetic properties of fisetin and its main metabolites following oral administration at a dose of 20 mg/kg/day in healthy volunteers and in older medical patients.

• Sub-study II aims to assess the safety and tolerability of oral treatment with fisetin at a dose of 20 mg/kg/day fisetin for two consecutive days in healthy volunteers and in older medical patients.

• Sub-study III aims to gather representative measurements to assess the utility of inflammation, SASP, senescence, senolysis, and aging biomarkers, as well as measures of frailty, clinical parameters, physical and cognitive function, and quality of life as potential outcomes in future clinical trials; additionally, to perform sample size calculations for future trials based on these data. ;
