Golimumab and Apalutamide for the Treatment of Castration-Resistant Prostate Cancer, TRAMP Study

OUTLINE: Patients receive golimumab subcutaneously (SC) every 4 weeks for 6 doses and apalutamide orally (PO) daily. Treatment with apalutamide continues in the absence of disease progression or unacceptable toxicity. Patients undergo tumor biopsy at baseline and during cycle 4. Patients also undergo computed tomography (CT) scans or magnetic resonance imaging (MRI), prostate-specific membrane antigen (PSMA) positron emission tomography (PET), bone scan, and collection of blood samples throughout the study. After completion of study treatment, patients are followed every 3 months.
