3 Cabozantinib has resulted in bone scan and symptom improvements in prostate cancer but no other solid tumor.

4 Which agent are you most likely to recommend for a patient with asymptomatic metastatic prostate cancer progressing on androgen deprivation?

5 To what extent does radium-223 chloride cause myelosuppression?

6 Updated Analysis of the Phase III, Double-Blind, Randomized, Multinational Study of Radium ‑ 223 Chloride in Castration-Resistant Prostate Cancer (CRPC) Patients with Bone Metastases (ALSYMPCA) Proc ASCO 2012;Abstract LBA 4512 C.

O’Bryan-Tear, J. Garcia-Vargas, M. Shan, and O. Sartor

7 Radium-223 Targets Bone Metastases Alpha-particles induce double-strand DNA breaks in adjacent tumor cells 1 Short penetration of alpha emitters (2-10 cell diameters) = highly localized tumor cell killing and minimal damage to surrounding normal tissue 1.

10 ESMO 2012 – Prostate ALSYMPCA: Radium-223 Chloride in mCRPC Parker C et al. Proc ESMO 2012;Abstract 898PD. –Updated analysis substantiates Ra-223 as an effective therapy that significantly improves OS and time to first SRE, with a highly favorable safety profile –Ra-223 showed significantly better preservation of QOL, with improved functioning and well-being, compared to Pbo in pts with bone metastasis
