Aim: This qualitative study aimed to reveal symptoms and impacts among bone metastatic castration-resistant prostate cancer (or mCRPC) Japanese patients, prior to Radium-223 (Ra-223) treatment. Materials & Methods: Twenty-three mCRPC patients designated to receive Ra-223 and three treating physicians (Ra-223 prescribers) in Japan, were interviewed. All interview data were assessed for concept frequency, themes and saturation. Results: Forty-five percent of the patients (mean age: 75.8 years) were symptomatic at the time of enrollment. Interviews with all patients revealed 47 mCRPC symptoms, including back pain and bone-specific pain, and 45 life impacts, including worry about disease progression and the impact on daily, physical activities. Conclusion: The symptoms and impacts of living with mCRPC and the associated burden of bone metastasis and skeletal-related symptoms are varied and are important considerations for treatment.

Secondary Endpoints

167 Background: The ALSYMPCA study was conducted to evaluate the alpha-emitting radiopharmaceutical Radium-223 Chloride (BAY 88-8223) in patients with symptomatic bone metastases in Castration resistant prostate cancer (CRPC). This trial met its primary endpoint of overall survival at the time of pre-planned interim analysis. Post hoc analysis showed a reduction from baseline in total ALP at 12 weeks (32% reduction in the BAY 88-8223 arm vs. 37% increase in placebo arm, P < 0.001) (Sartor et al. ASCO 2013). We are reporting here a single-arm, open-label, multicenter, phase II clinical study of BAY 88-8223 in Japanese patients with symptomatic CRPC with bone metastases. Methods: Eligible patients had progressive, symptomatic CRPC with at least 2 bone metastases on bone scintigraphy and no known visceral metastases; were receiving Best Standard of Care; and either had previously received docetaxel, were docetaxel ineligible, or had refused docetaxel. Patients received 6 injections of radium-223 (50 kBq/kg IV) every 4 weeks. The primary endpoint was percentage of change in total ALP from baseline at 12 weeks. Secondary endpoints included overall survival, time to symptomatic skeletal event, percentage of change in bone ALP/PSA/biomarkers, and safety. Results: A total of 67 subjects were enrolled; 18 were screening failures, and 49 were received to the study treatment and received at least one administration from September 2013 to May 2014. The mean percent change in total ALP from baseline at 12 weeks was -19.3% (95%CI: -28.0% to -10.7%). The results of secondary endpoints will be presented. The safety and tolerability profile for BAY 88-8223 were highly favorable and only 1 subject (2.0%) experienced lymphocyte count decreased as a Grade 4 adverse event, and there was no death during the study treatment and within 30 days after the last injection of study treatment. Conclusions: The reduction from baseline in total ALP at 12 weeks seen in this phase II study is consistent with the results shown in ALSYMPCA study. Overall, BAY 88-8223 was well tolerated in Japanese patients with CRPC and bone metastases. Clinical trial information: NCT01929655.

Abstract: The treatment of metastatic prostate cancer can be divided into two pathophysiological phases: hormone-sensitive and castration-resistant phases. Huggins’ observation in the year 1941, which was awarded with the Nobel Prize in 1966, has a key role in treatment during the hormone-sensitive phase, stating that if the testicles are removed, the size of the prostate cancer decreases. Inducing androgen deprivation, i.e., testosterone depletion is the basic treatment of metastatic prostate cancer that patients have to receive life-long. In the past eight years, five new agents have been approved besides docetaxel in the treatment of metastatic castration-resistant prostate cancer: sipuleucel-T, cabazitaxel, abiraterone, enzalutamide, and radium-223. With the sequential application of these agents, significant improvement can be achieved in survival. Besides the latest developments, the hormone-sensitive phase has become the focus of attention, especially in the treatment of patients with de novo metastases and poor prognosis. Many studies have proven the outstanding efficacy of adding early docetaxel and abiraterone to androgen deprivation therapy. The authors give a detailed overview of clinical studies leading to a paradigm change in treatment during the hormone-sensitive phase, and call attention to the difficulties encountered in Hungarian practice.
