Likelihood of response to abiraterone or enzalutamide after initial response and PD with the other?


Likelihood of response to abiraterone or enzalutamide after initial response and PD with the other?

In a patient with a response and then disease progression on enzalutamide, what is the likelihood that a patient with mCRPC will derive clinically meaningful benefit that will be evident to the patient and/or physician with abiraterone?
