Radiographic Progression Free Survival (rPFS)Primary· From study start up to 3 years
Defined as the time from study start until one of the following events occurs: \>= 2 new bone lesions on technetium bone scan; Response Evaluation Criteria in Solid Tumors (RECIST)-defined tumor progression; clinical deterioration requiring a change in prostate cancer therapy, or at clinician discretion; surgery or radiation to treat a prostate cancer related indication; or death from any cause.

Time to PSA ProgressionSecondary· Time between the first evaluation at which the response criteria are met and the first documentation of PSA progression or death or up to 3 years
Time between the first evaluation at which the response criteria are met and the first documentation of PSA (Prostate-Specific Antigen) progression or death. Progression is defined as a rise in PSA of 50% above nadir value or 25% above baseline if there is no decline.

This phase II trial studies selinexor in treating patients with prostate cancer that has spread to other parts of the body (metastatic), keeps growing even when the amount of testosterone in the body is reduced to very low levels (castration-resistant), and did not respond to treatment (refractory) with abiraterone acetate and/or enzalutamide. Selinexor may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
