Enzalutamide and abiraterone acetate plus prednisone, which target the androgen receptor axis, have expanded the treatment of advanced prostate cancer. Retrospective analyses suggest some cross-resistance between these two drugs when used sequentially, but robust, prospective studies have not yet been reported. ⋯ Patients with mCRPC who progressed on previous abiraterone acetate plus prednisone treatment, with or without prior chemotherapy, received enzalutamide. Although cross-resistance between the two agents was observed in a majority of patients, some still benefited from enzalutamide treatment.

Randomized Controlled Trial Multicenter Study Comparative Study
Two-Year Outcomes of Sacral Neuromodulation Versus OnabotulinumtoxinA for Refractory Urgency Urinary Incontinence: A Randomized Trial.
Urgency urinary incontinence (UUI) is a chronic condition for which sacral neuromodulation (SNM) (InterStim/Medtronic) and onabotulinumtoxinA (BTX) (BotoxA/Allergan) are utilized. These therapies have not been compared over extended time. ⋯ We compared a large group of US women with severe urgency urinary incontinence (UUI) who received sacral neuromodulation (InterStim) or onabotulinumtoxinA (Botox A) therapy during a 2-yr period. We found that both therapies had similar success in reducing UUI symptoms, and adverse events were low. However, women in the BotoxA group had higher satisfaction and endorsement with their treatment, but with a higher chance of a urinary tract infection. We conclude that both therapies offer sustained reduction in daily incontinence over 2 yr.
