Clinical Trial Summary

This phase II trial studies the effects of stereotactic body radiation therapy (SBRT) and the timing of treatment with androgen receptor pathway inhibitor (ARPI) plus androgen deprivation therapy (ADT) in treating patients with hormone sensitive prostate cancer that has spread from where it first started to other places in the body (metastatic), and that has come back after a period of improvement (recurrent). SBRT is a type of external radiation therapy that uses special equipment to position a patient and precisely deliver radiation to tumors in the body (except the brain). The total dose of radiation is divided into smaller doses given over several days. This type of radiation therapy helps spare normal tissue. Androgen can cause the growth of prostate cells. ADT lowers the amount of androgen made by the body. This may help stop the growth of tumor cells that need androgen to grow. Androgen receptor pathway inhibitors work by blocking the effects of androgen to stop the growth and spread of tumor cells. Giving SBRT alone with watchful waiting may be as effective in treating prostate cancer as giving SBRT together with ARPI and ADT.

Description:

PRIMARY OBJECTIVES:

I. To evaluate and compare modified radiographic progression-free survival (mrPFS) in patients with metachronous recurrent oligometastatic prostate cancer treated with SBRT and 6 months ADT/ARPI followed by watchful wait (Group A) versus SBRT followed by watchful wait (Group B).

SECONDARY OBJECTIVES:

I. To evaluate and compare overall survival (OS) between two treatment groups. II. To evaluate and compare biochemical progression-free survival (bPFS) between two treatment groups.

III. To evaluate and compare time to local progression between two treatment groups.

IV. To evaluate and compare time to distant progression between two treatment groups.

V. To evaluate the toxicity profile of 6 months of ADT/ARPI as assessed per National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE).

TERTIARY OBJECTIVES:

I. To evaluate and compare castration-resistant prostate cancer (CRPC)-free survival between two treatment groups NOTE: CRPC-free survival: radiographic progression-free survival with castrate-level testosterone (< 50ng/mL).

II. Determine the efficacy of extracellular vesicles (EVs) as a minimal residual disease (MRD) marker.

III. Determine the efficacy of EVs as an early indicator of disease relapse. IV. Characterize duration of response. V. Determine whether early ADT and ARPI hasten CRPC. VI. Determine how circulating tumor deoxyribonucleic acid (ctDNA) compares as a biomarker to EVs.

OUTLINE: Patients are randomized to 1 of 2 groups.

GROUP A: Patients undergo SBRT and receive ARPI (abiraterone and prednisone, apalutamide, darolutamide, or enzalutamide) and ADT (leuprolide, triptorelin, histrelin, goserelin, degarelix, or relugolix). Cycles repeat every 4 months (16 weeks) for up to 6 months in the absence of disease progression or unacceptable toxicity. Patients then undergo watchful waiting thereafter until disease progression.

GROUP B: Patients undergo SBRT with watchful waiting. Cycles repeat every 4 months (16 weeks) in the absence of disease progression or unacceptable toxicity.

Additionally, patients undergo blood sample collection and positron emission tomography (PET), computed tomography (CT), magnetic resonance imaging (MRI), or bone scan.

Upon completion of study interventions patients are followed up every 6 months for up to 5 years.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Modified radiographic progression-free survival (mrPFS)	Modified radiographic progression-free survival (mrPFS) is defined as the time from the date of randomization (enrollment to study) to the date of the first occurrence of either death due to any cause or radiographic progression per prostate cancer working group 3 criteria, which are not addressable by stereotactic body radiation therapy (SBRT). Radiographic progression not addressable by SBRT includes 1) soft tissue lesions measured by response evaluation criteria in solid tumors (RECIST) v1.1 or 2) bone lesions evaluated only on bone scans per 2+2 rule (2 new lesions on the 1st post-treatment scan plus 2 additional new lesions on the subsequent scan with persistence or 2 new lesions compared to 1st post-treatment scan persisting on the follow-up scan). Date of progression is the first scan showing lesions. Radiographic progression disease that can be addressed by SBRT will not be an mrPFS event.	Up to 5 years
Secondary	Overall survival (OS)	Defined as time from the date of randomization (enrolled to study) to the date of death due to any cause.	Up to 5 years
Secondary	Biologic progression-free survival (bPFS)	Defined as time from the date of randomization (enrollment to study) to the date of death due to any cause or biologic progressive disease, whichever occurs first.	Up to 5 years
Secondary	Time to local progression (TLP)	Defined as time from date of randomization (enrollment to study) to the date of the first documented local progression. Local progression includes growth of any existing lesion by 20% or more that persists on a subsequent scan (modified from RECIST 1.1), whether or not these lesions are or can be addressed by radiotherapy.	Up to 5 years
Secondary	Time to distant progression (TDP)	Defined as time from date of randomization (enrollment to study) to the date of the first documented distant progression. Distant progression includes new lesions on imaging, whether or not these lesions are or can be addressed by radiotherapy.	Up to 5 years
Secondary	Adverse event (AE) rate	Defined as the proportion of patients experienced at least one Grade 3, Grade 4, or Grade 5 of any type of AE during the protocol defined treatment. AEs will be assessed using common terminology criteria for adverse events (CTCAE) v5.0.	Up to 5 years
