About this study
Official title: A Randomized Phase II/III Trial Evaluating Bipolar Androgen Therapy Followed by Darolutamide vs. Standard of Care in Patients With Metastatic Castration Resistant Prostate Cancer
This phase II/II trial compares the effect of high dose testosterone followed by darolutamide with the usual care in treating patients with prostate cancer that has spread from where it first started (primary site) to other places in the body (metastatic) and keeps growing even when the amount of testosterone in the body is reduced to very low levels (castration-resistant). Usual care treatment for patients with metastatic prostate cancer includes surgery or medical castration which involves drugs to suppress the function of the testes. After receiving this therapy, a period of disease stability occurs, followed typically by cancer regrowth and castration-resistant disease. Castration-resistant prostate cancer occurs because the tumor cells are eventually able to adapt to the very low levels of testosterone in the body. A new type of therapy called Bipolar Androgen Therapy (BAT) involves giving patients very high doses of testosterone every 28 days. This results in a cycle of higher than normal testosterone levels (i.e., "supraphysiologic") to near castrate levels over the 28 days. BAT may be able to stop prostate tumor cells from becoming castrate-resistant. In this trial, patients who receive BAT with high dose testosterone and experience disease progression then receive darolutamide. Darolutamide is in a class of medications called androgen receptor inhibitors. It works by blocking the effects of androgen (a male reproductive hormone) to stop the growth and spread of tumor cells. Adding BAT with high dose testosterone prior to darolutamide after disease progression may help shrink or stabilize metastatic castration-resistant prostate cancer better than usual treatments alone.
Read the detailed description
PRIMARY OBJECTIVES:
- To evaluate if BAT followed by darolutamide (Arm B) is associated with improved second progression-free survival (PFS2) post second treatment compared to physician's choice standard of care (SOC)1 followed by SOC2 (Arm A) in men with mCRPC who have progressed on prior androgen receptor pathway inhibitor (ARPI). (Phase II) II. To evaluate if BAT followed by darolutamide (Arm B) is associated with improved overall survival (OS) compared to physician's choice SOC1 followed by SOC2 (Arm A) in men with mCRPC who have progressed on prior ARPI. (Phase III) III. To compare overall quality of life, measured by Functional Assessment of Cancer Therapy-Prostate (FACT-P) total score, between Arms A and B. (Quality of Life [QOL] objective)
SECONDARY OBJECTIVES:
- To evaluate the radiographic progression-free survival (PFS) following initial randomization (Arm A SOC1 versus [vs] Arm B BAT) and following second treatment (Arm A SOC 2 vs Arm B darolutamide) as determined using Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria (for soft tissue metastases) and Prostate Cancer Working Group 3/PCWG3 criteria (for bone metastases).
II. To evaluate the PSA50 response (PSA decline ≥ 50% from baseline) rate following initial randomization (Arm A SOC1 vs Arm B BAT) and following second treatment (Arm A SOC2 vs Arm B darolutamide).
III. To evaluate the radiographic response rate following initial randomization (Arm A SOC1 vs Arm B BAT) and following second treatment (Arm A SOC2 vs Arm B darolutamide) per RECIST 1.1 criteria.
IV. To evaluate the incidence and severity of adverse events according to the National Cancer Institute's Common Terminology Criteria for Adverse Events (CTCAE).
- To compare overall quality of life, measured by FACT-P total score, at 12 weeks between Arms A and B. (QOL objective) VI. To compare the change in overall QOL, measured by FACT-P total score, from baseline to 12 weeks between Arms A and B. (QOL objective) VII. To compare patient-reported fatigue (Functional Assessment of Chronic Illness Therapy-Fatigue [FACIT-Fatigue] scores) at 12 weeks between Arms A and B. (QOL objective) VIII. To compare patient-reported overall QOL (FACT-P scores), and fatigue (FACIT-Fatigue scores) between Arms A and B at the time of first and second disease progression. (QOL objective) IX. To characterize longitudinal change in overall QOL (FACT-P) and fatigue (FACIT-Fatigue between baseline and second disease progression in Arms A and B. (QOL objective)
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM A: Patients receive an SOC1 treatment regimen per discretion of the patient and the treating provider: 1) Docetaxel intravenously (IV) every 21 days with or without prednisone; OR 2) Abiraterone acetate orally (PO) once daily (QD) with prednisone or methylprednisolone or dexamethasone; OR 3) Enzalutamide PO QD. SOC1 treatment continues in the absence of disease progression or unacceptable toxicity. Patients experiencing disease progression then receive an SOC2 treatment regimen per discretion of the patient and the treating provider: 1) Docetaxel IV every 21 days with or without prednisone; OR 2) cabazitaxel IV every 21 days; OR 3) lutetium Lu 177 vipivotide tetraxetan (177Lu-PSMA-617) IV every 6 weeks for 6 doses; OR 4) Abiraterone acetate PO QD with prednisone or methylprednisolone or dexamethasone; OR 5) Enzalutamide PO QD. SOC2 treatment continues in the absence of disease progression or unacceptable toxicity. Patients also undergo computed tomography (CT) or magnetic resonance imaging (MRI), bone imaging, and biospecimen collection throughout the study.
ARM B: Patients receive testosterone cypionate intramuscularly (IM) on day 1 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients experiencing disease progression then receive darolutamide PO twice daily (BID) in the absence of disease progression or unacceptable toxicity. Patients also undergo CT or MRI, bone imaging, and biospecimen collection throughout the study.
After completion of study treatment, patients are followed every 3 months for 24 months from randomization and then every 6 months for 60 months from randomization.

What is being measured
The primary outcome is the main question the study is designed to answer.
Second progression-free survival (PFS2) (Phase II)
Definition of progression includes radiographic progression per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 or Prostate Cancer Working Group 3 (PCWG3) for bone lesions, and clinical progression determined by treating physician. The phase II part will be conducted first and only if the treatment of Bipolar Androgen Therapy (BAT) followed by darolutamide significantly improves PFS2 compared to the SOC (SOC1 followed by SOC2) arm, then the study will continue to the phase III part. The primary comparisons will be an intention-to-treat analysis including all randomized patients. The phase II part of the study will have 89.5% power to detect the above difference in PFS2 using a one-sided 0.15 level stratified log-rank test.
Measured: From randomization to disease progression or death, whichever occurs first after initiation of second treatment (standard of care [SOC]2 or darolutamide), assessed up to 60 months
Overall survival (OS) (Phase III)
The phase II part will be conducted first and only if the treatment of BAT followed by darolutamide significantly improves PFS2 compared to the SOC (SOC1 followed by SOC2) arm, then the study will continue to the phase III part. The primary comparisons will be an intention-to-treat analysis including all randomized patients.
Measured: From randomization until death from any cause or date last known alive, assessed up to 60 months
Overall quality of life (QOL)
Will compare overall QOL, measured by Functional Assessment of Cancer Therapy-Prostate (FACT-P) total score, between the two arms. Mixed-effects models will be constructed, utilizing all available data, with fixed effects for treatment arm, assessment time, and the treatment-by-time interactions. A random intercept per patient will be included to account for within-subject correlations.
Patients will rate physical, social/family, emotional, and functional well-being along with additional concerns on a scale from "not at all" to "very much". Interpretation of higher vs. lower scores being better is dependent on which subsection is being scored (i.e."I am able to work" rated as very much is not comparable to "I feel sad" rated as very much).
Measured: At randomization,12, 24 and 48 weeks after randomization
Secondary outcomes (16)
Progression-free survival (PFS)
Will be determined using RECIST 1.1 criteria (for soft tissue metastases) and PCWG3 criteria (for bone metastases). Will be evaluated for each of the two treatments in a given arm.
