Clinical Trial Summary

This phase II trial compares the effect of relugolix to leuprolide on cardiac function and performance in patients with prostate cancer. Androgen deprivation therapy (ADT) has been a key component for the treatment of advanced prostate cancer for decades. The term androgen deprivation therapy means lowering a man's testosterone. Long-term studies show that ADT may contribute to a detriment to cardiac health and predisposes men to developing cardiac diseases. Recent studies suggest that men taking relugolix for treatment of prostate cancer may have a lower risk of developing cardiovascular problems, but more studies are needed to understand this observation, and there are currently no studies reporting the direct impact of ADT (relugolix, versus the more-commonly used leuprolide) on cardiac function and outcomes.

Participants will receive definitive radiotherapy for unfavorable intermediate risk prostate cancer and 6-month ADT (either relugolix or leuprolide). In addition, participants will undergo the following:

1. Comprehensive cardiac and exercise testing before and after starting ADT

2. Completion of quality-of-life questionnaires at specific intervals during the study period

3. Provide blood samples at specific intervals during the study period to test for changes in steroid levels and certain biomarkers

Description:

PRIMARY OBJECTIVES:

I. To quantify the physiologic alterations in cardiopulmonary function in men receiving 6-month relugolix verse (vs.) 6-month leuprolide with definitive radiation therapy (RT) for unfavorable intermediate risk (UIR) clinically localized prostate cancer (PCa).

II. Cardiopulmonary and cardiac measures obtained from: 1) exercise stress cardiac magnetic resonance imaging (MRI) perfusion, and 2) maximal rate of oxygen consumption (VO2), include myocardial perfusion reserve index (MPRI), contractile reserve, myocardial longitudinal relaxation time (T1) signal, longitudinal strain, circumferential strain, VO2 maximum (max), and metabolic equivalents of exercise capacity (METs).

SECONDARY OBJECTIVES:

I. To quantify the impact of 6-month relugolix vs. leuprolide with definitive RT for UIR PCa on quality of life (QoL) using Expanded Cancer Index Composite (EPIC)-26, European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), European (Euro) Qol-5-Dimension 5-level (EQ-5D-5L), and Patient Reported Outcomes Measurement Information System (PROMIS) Fatigue (Short Form 8a) patient-reported outcome surveys, or similar tests.

II. To quantify the impact of 6-month relugolix vs. leuprolide on composite functional tests of strength and balance using three tests: 1) Timed Up-and-Go, 2) 10-meter walk time, and 3) grip strength.

III. To analyze body composition changes in response to 6-month relugolix vs. leuprolide by using abdominal computed tomography (CT) or magnetic resonance imaging (MRI) to quantitate abdominal/visceral fat and lean muscle mass with utilization of SliceOmatic software.

EXPLORATORY OBJECTIVES:

I. To compare changes in serum steroid profiles (panel of 17 steroid hormone metabolites, Ohio State University Comprehensive Cancer Center [OSUCCC Pharmacoanalytic Shared Resource [PhASR]) before, during and after 6-month relugolix vs. 6-month leuprolide with definitive RT for UIR PCa.

II. To compare changes in cardiometabolic biomarkers in the following three categories: 1) glycemic control parameters (fasting glucose, fasting insulin, and connecting [C]-peptide), 2) lipid profiles (total cholesterol, triglyceride, low-density lipoprotein [LDL], high-density lipoprotein [HDL], and leptin/adiponectin ratio), 3) markers of the obesity-associated low-grade chronic inflammatory state (CRP, TGF-beta, and IL-6, and novel related immunoregulators), and targeted or non- targeted metabolomics or proteomics (by OSUCCC NPASR and PSR) depending on procurement of additional funds.

III. To compare the time course of recovery for hormonal and cardiometabolic markers after completion of 6-month relugolix vs. 6-month leuprolide with definitive RT for UIR PCa.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM 1: Patients receive definitive therapy for prostate cancer with ADT (leuprolide via injection once every 3 months, for a total of 6 months) in the absence of disease progression or unacceptable toxicity and definitive radiotherapy within 90 days of starting ADT. Patients receive gadolinium-based contrast intravenously (IV) and undergo exercise-stress cardiac MRI perfusion and comprehensive exercise physiology testing before starting ADT and at 6 months after starting ADT. Patients also undergo blood and urine sample collection throughout the study, as well as completion of quality-of-life questionnaires.

ARM 2: Patients receive definitive therapy for prostate cancer with ADT (relugolix orally once daily for a total of 6 months) in the absence of disease progression or unacceptable toxicity and definitive radiotherapy within 90 days of starting ADT. Patients receive gadolinium-based contrast intravenously (IV) and undergo exercise-stress cardiac MRI perfusion and comprehensive exercise physiology testing before starting ADT and at 6 months after starting ADT. Patients also undergo blood and urine sample collection throughout the study, as well as completion of quality-of-life questionnaires.

After completion of study treatment, patients are followed up at 1, 3, and 6 months.

• = 50% of biopsy cores positive

• Biopsies may include "sextant" sampling of right/left regions of the prostate, often labeled base, mid-gland and apex. All such "sextant" biopsy cores should be counted. Men may also undergo "targeted" sampling of prostate lesions (guided by MRI, ultrasound or other approaches). A targeted lesion that is biopsied more than once and demonstrates cancer (regardless of number of targeted cores involved) should count as a single additional positive core sampled and positive.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Physiologic alterations in cardiopulmonary function - Myocardial perfusion	We will measure the difference in myocardial perfusion with exercise stress-rest cardiac MRI before and after ADT (leuprolide vs. relugolix).	Up to 6 months
Primary	Physiologic alterations in cardiopulmonary function - Maximal rate of oxygen consumption	We will measure the difference in VO2 Max before and after ADT (leuprolide vs. relugolix).	Up to 6 months
Secondary	Quality of life using EPIC-26	Response options for each EPIC item form a Likert scale, and multi-item scale scores are transformed linearly to a 0-100 scale. Overall, higher scores across the EPIC domains represent better QoL.	Up to 6 months
Secondary	Quality of life using EORTC QLQ-C30	All of the scales range in score from 0 to 100. A high score for a functional scale represents a high/healthy level of functioning.	Up to 6 months
Secondary	Quality of life using European (Euro) Qol-5-Dimension 5-level (EQ-5D-5L)	This validated utility assessment instrument evaluates 5-dimensions (5D) of function, including mobility, self-care, usual activities, pain/discomfort, and anxiety/depression, each graded on 5 levels (ranging from 1 [no problem] to 5 [extreme problems]). The 5D index score is transformed into a utility score between 0 and 1. The sixth item is a visual analogue scale for overall health perceived by the patient. A lower score represents better health.	Up to 6 months
Secondary	Quality of life using PROMIS	A 5-point Likert scale from 1 (never/not at all) to 5 (almost always/very much) with a recall period of last 7 days. The T-score rescales the raw score into a standardized score with a mean of 50 and a standard deviation (SD) of 10. Therefore, a person with a T-score of 40 is one SD below the mean.	Up to 6 months
Secondary	Functional tests of strength and balance using Timed Up-and-Go	Participants will be instructed to stand up from an armchair (seat height of 45 cm), walk at a comfortable pace to a line on the floor 3 meters away, turn, return to the chair and sit down again. A stopwatch is used to time the performance (in seconds).	Up to 6 months
Secondary	Functional tests of strength and balance using 10-meter walk time	Gait speed will be measured using a standardized 10-m course.	Up to 6 months
Secondary	Functional tests of strength and balance using Grip strength	A validated biomarker of overall strength and muscle mass. Patients will perform 3 trials with each hand, alternating hands between trials, with the maximum score for each hand being recorded.	Up to 6 months
Secondary	Changes in body composition	Abdominal CT/MRI to quantitate abdominal/visceral fat and lean muscle mass with utilization of image analysis software.	Up to 6 months
