This phase II trial evaluates apalutamide in combination with image-guided stereotactic body radiation therapy (SBRT) for the treatment of patients with prostate cancer. Prostate cancer usually needs the hormone testosterone to grow. Apalutamide is a hormone therapy that blocks the effect of testosterone on prostate tumor cells. This may help stop the growth of tumor cells that need testosterone to grow. Image-guided SBRT is a standard treatment for some types of prostate cancer. This treatment combines imaging of cancer within the body, with the delivery of therapeutic radiation doses produced on a linear accelerator machine. SBRT uses special equipment to position a patient and deliver radiation to tumors with high precision. This method may kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. Combining apalutamide with image-guided SBRT may increase a prostate cancer patient's chances of achieving an extremely low prostate specific antigen response, which is an early predictor of disease cure.

---|---|---|---|---|
Primary | Percent of patients achieving prostate specific antigen (PSA) of < 0.2 ng/mL | Will be summarized by count and percent along with the 95% confidence interval. This will then be compared to the historical control rate of 70% using a two sample z test for proportions with a one-sided p-value threshold of 0.05. | Three months after completion of apalutamide | |
Secondary | Time to biochemical recurrence (BCR) | Evaluated among patients initially meeting the primary endpoint. BCR is defined as PSA >= nadir PSA + 2 ng/mL. Time to BCR will be reported descriptively for each patient. Five-year biochemical recurrence free survival will be estimated by the Kaplan-Meier method as well as descriptively (mean, standard deviation, median, first and third quartiles, minimum, maximum). | We will follow patients for five years following completion of radiotherapy. Biochemical disease status will be checked every 3 months for the first year, and every 6 months thereafter. | |
Secondary | Patient-reported outcomes (PROs) on the Expanded Prostate Cancer Index Composite-26 (EPIC-26) urinary domain | Changes will be analyzed with respect to whether they represent minimally important differences. | 24 months after completion of stereotactic body radiation therapy (SBRT) | |
Secondary | PROs on the EPIC-26 bowel domain | The analysis of both acute and late changes in the bowel domain of the EPIC instrument will be stratified for use of hydrogel spacers or not, as these may reduce both acute and late gastrointestinal bowel symptoms. | 24 months after completion of SBRT | |
Secondary | Radiographic persistence of disease on prostate specific membrane antigen (PSMA) positron emission tomography/computed tomography (PET/CT) | Defined by expert reader using the criterion of standardized uptake value within 20% of pre-SBRT PSMA PET/CT. Will be reported as a binary value (persistent versus not persistent). | 6 months after hormonal therapy completion | |
Secondary | Radiographic persistence of disease on multiparametric magnetic resonance imaging | Defined by expert reader using a composite of apparent diffusion coefficient, size, and ktrans. Will be reported as a binary value (persistent vs. not persistent). | At 6 months, 12 months, 18 months, 24 and 30 months after radiotherapy completion | |
Secondary | Longitudinal PROs on the EPIC-26 questionnaire in the sexual, urinary, and bowel domains | For the EPIC-26 instrument, these will be represented by changes from baseline in the urinary incontinence, urinary obstruction, bowel, sexual function, and hormone/vitality domains. Changes will be analyzed with respect to whether they represent minimally important differences. | Up to 60 months | |
Secondary | Physician-reported acute and late toxicities | Evaluated per the Common Terminology Criteria for Adverse Events scale version 5.0. Rates will be reported descriptively. The 5-year cumulative incidences of late grade = 2 genitourinary and gastrointestinal toxicity will be analyzed using a cumulative incidence framework. The analysis of gastrointestinal toxicities (acute and late) will be stratified by the use of hydrogel spacers. | We will follow patients for five years following completion of radiotherapy. Acute toxicity will be scored within the first 90 days after radiation. Late toxicity and patient-reported outcomes will be assessed every 3 months for the first year, and every |
