ADRIAN: Towards Understanding Between ADT Treatment, Circadian Rhythm, and Physiological Responsiveness
Study Details
Study Description
Brief Summary
Frailty is one of the main reasons older adults lose independence. Frailty describes a reduced ability to withstand stress on the physiological scale, or a reduced physiological reserve. We theorize that entrainment of circadian rhythm via time-restricted eating will improve the body's ability to predict energy supply and demand, and therefore enable the body to allocate more resources to anabolic processes and promote resilience to cancer treatment, thereby preventing the progression of frailty. We will recruit 30 individuals over 55 years old undergoing ADT therapy for prostate cancer. Participants will be randomized 1:1 to a 12-week TRE intervention or a time-unrestricted nutrition control intervention. At baseline and post-intervention, we will assess frailty using Fried's Frailty Index and a novel set of five physiological responsiveness measures-1) lying-to-standing blood pressure, 2) heart rate variability, 3) oral glucose tolerance test, 4) 24-hour circadian cortisol rhythm, and 5) usual vs. fast gait speed. These data will allow us to 1) test the feasibility of TRE among patients with prostate cancer during ADT treatment with the ultimate goal of optimizing an intervention to prevent the progression of frailty, and 2) assess the effects of TRE vs. control on frailty and physiological responsiveness.

Detailed Description
Frailty affects more than 5.4 million people over the age of 65 in the United States (>10%) and is one of the main reasons older adults lose independence. Frailty describes a reduced ability to withstand stress on the physiological scale, or a reduced physiological reserve.
It is characterized by five key signs and symptoms, known as Fried's frailty criteria:
weakness, slow walking speed, low physical activity, fatigue or exhaustion, and unintentional weight loss. Frailty does not progress linearly; its pathogenesis often accelerates in response to a "stressor event" such as an illness (e.g., coronavirus), the death of a spouse, or cancer treatment. For example, a diagnosis with prostate cancer and androgen deprivation therapy (ADT) treatment are associated with accelerated frailty. While the body is resilient to everyday stressors, these large-scale, enduring stressors can accumulate and cause the body to have difficulty predicting energy supply and demand. The result is that stress-induced energy costs compete with cellular growth, maintenance, and repair, i.e., frailty. Treatments for frailty are intensive (e.g., weight training) and often unsuccessful, and there is a critical need to develop effective interventions to complement and replace these interventions to prevent and treat frailty.
We theorize that entrainment of circadian rhythm, or the body's internal body clock, will improve the body's ability to predict energy supply and demand, and therefore enable the body to allocate more resources to anabolic processes and promote resilience to cancer treatment, thereby preventing the progression of frailty. Time-restricted eating (TRE) entails consuming food within a defined, consistent window every day. It has emerged as a powerful intervention to entrain circadian rhythm and regulate metabolic homeostasis. We hypothesize that, by entraining circadian rhythm, TRE can enhance physiological regulation and prevent stressor-induced frailty.
We propose to recruit 30 patients over 55 years old undergoing ADT therapy for prostate cancer. Participants will be randomized 1:1 to a 12-week TRE intervention or a time- and attention nutrition control; both groups will be under the supervision of a licensed clinical nutritionist with expertise in the cancer population to ensure adequate macronutrient intake. At baseline and post-intervention, we will assess a novel set of six physiological responsiveness measures and frailty using Fried's Frailty Index. These data will allow us to Aim 1) test the feasibility of TRE among patients with prostate cancer during ADT treatment with the ultimate goal of optimizing an intervention to prevent the progression of frailty and Aim 2) test the effects of TRE on: a) Fried's Frailty Index, b) lying-to-standing blood pressure, c) heart rate variability, d) oral glucose tolerance, e) 24-hour circadian cortisol rhythm, and f) usual vs. fast gait speed.
This project is innovative and clinically important because once frailty is diagnosed, it is difficult to treat. This project tests a novel theoretical framework that a low cost, widely accessible dietary intervention-TRE-can entrain circadian rhythm and improve physiological reserve in the context of ADT treatment for prostate cancer, thereby preventing progression to frailty.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Time-restricted eating Participants will meet with a nutritionist to discuss dietary recommendations for patients with prostate cancer undergoing ADT. Participants will self-select a 10-hour window in which to consume all food and beverages (with the exception of black coffee and unsweetened tea in the mornings; water is okay at all times). |
Behavioral: Dietary recommendations
One-on-one meeting with a nutritionist to discuss and personalize dietary recommendations for patients with prostate cancer undergoing ADT.
Behavioral: Time-restricted eating
12 weeks of time-restricted eating (10-hour window)
|
| Active Comparator: Unrestricted eating Participants will meet with a nutritionist to discuss dietary recommendations for patients with prostate cancer undergoing ADT. Participants will try to follow recommendations will no suggestion for meal timing. |

Outcome Measures
Primary Outcome Measures
- Feasibility, as assessed by the percentage of participants who enrolled completed the study [12 weeks]
To assess feasibility, the percentage of participants who provide evaluable data regarding their eating window at baseline and 12 weeks will be assessed.
Secondary Outcome Measures
- The effects of TRE on frailty, as measured using Fried's Frailty criteria [12 weeks]
Fried's Frailty scores will be compared for those in the time-restricted eating group vs. the control group at week 12, controlling for baseline levels. This assessment entails recent weight loss, handgrip strength, self-reported exhaustion, walking speed; and habitual physical activity
