Aging and cigarette smoke exposure have both been associated with cellular senescence, a biological process characterized by the accumulation of dysfunctional cells that may contribute to progressive decline in organ function. The study investigates whether intermittent administration of fisetin can favorably influence lung physiology and biological markers associated with aging.\n\nParticipants will be randomized to receive either fisetin or placebo and will undergo a short-course treatment regimen using a \"hit-and-run\" approach intended to transiently target senescent cells. The study population includes older adults with and without a history of cigarette smoking to allow assessment across groups with differing risk for accelerated pulmonary aging.\n\nStudy procedures include clinical evaluations, pulmonary function testing, exercise-based assessments, electrocardiography, laboratory testing, and collection of blood and urine samples for analysis of biomarkers related to cellular senescence and aging. Participants will be followed over a two-week study period, during which safety, tolerability, and protocol feasibility will be assessed. The results of this pilot study are intended to inform the design of future trials evaluating senolytic therapies as potential interventions for age-related declines in lung function and health.",[44,50],{"label":45,"type":46,"description":47,"interventionNames":48},"Fisetin","EXPERIMENTAL","Participants receive oral fisetin at approximately 20 mg\u002Fkg\u002Fday for 2 consecutive days on Days 1-2 and again on Days 8-9 using a senolytic \"hit-and-run\" dosing strategy.",[49],"Drug: Fisetin",{"label":51,"type":52,"description":53,"interventionNames":54},"Placebo","PLACEBO_COMPARATOR","Participants receive matching placebo capsules administered on the same schedule as the fisetin arm (Days 1-2 and Days 8-9).",[55],"Drug: Placebo",[57,61],{"type":58,"name":45,"description":59,"armGroupLabels":60,"otherNames":29},"DRUG","Participants randomized to the experimental arm will receive oral fisetin capsules administered at a target dose of approximately 20 mg\u002Fkg\u002Fday for 2 consecutive days on Days 1-2 and again on Days 8-9.
