Trial Title: Phase I/II Study of ASP9521 in Castrate-Resistant Prostate Cancer (CRPC) Patients

Study Design Characteristics:
- Allocation: None
- Intervention Model: SINGLE_GROUP
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: NONE
- Phase: PHASE1/PHASE2
- Number of Arms: 1.0

Eligibility Criteria:
Inclusion Criteria:~* Histologically confirmed adenocarcinoma of the prostate without neuroendocrine differentiation or small cell features~* Metastatic disease documented by 2 or more bone lesions on bone scan or by soft tissue disease observed by Computed tomography/Magnetic resonance imaging (CT/MRI)~* Ongoing androgen deprivation with Luteinizing hormone-releasing hormone (LHRH) agonist/antagonist therapy or bilateral orchiectomy. For patients who have not had an orchiectomy, there must be a plan to maintain effective LHRH agonist/antagonist therapy for the duration of the study~* Serum testosterone \<1.7 nmol/L (50 ng/dL) at screening~* Patients receiving bisphosphonates or other approved bone targeting therapy must have been on stable doses for at least 4 weeks prior to screening~* Progressive disease at study entry defined as one or more of the following 3 criteria occurring in the setting of castrate levels of testosterone:~  * Prostate-specific antigen (PSA) progression defined by a minimum of 2 rising PSA levels with an interval of \>1 week between each determination. The PSA value at screening should be \>2 ng/mL~ * Soft tissue disease progression defined by Response Evaluation Criteria in Solid Tumors (RECIST). Measurable disease is not required for entry. Lymph nodes \>20 mm are considered measurable disease~ * Bone disease progression defined by at least 2 new lesions on bone scan~* Life expectancy of \>6 months according to the investigator's judgment~* Chemotherapy-Naïve patients should be asymptomatic or controlled symptomatic patients with metastatic CRPC who have failed one or more lines of hormonal treatment/androgen deprivation therapy but have not received chemotherapy or have refused chemotherapy. Post chemotherapy patients should have received not more than two prior regimens of chemotherapy for prostate cancer, of which one is docetaxel-based~Exclusion Criteria:~* Concomitant treatment with the following is prohibited:~  * All biologic agents (except for sipuleucel T \[Provenge®\]), or other agents with anti-tumor activity against prostate cancer, including 5 alpha reductase inhibitors, androgens (e.g., testosterone), cytoproterone acetate and all other progestational agents, estrogens, and flutamide within 4 weeks prior to screening~ * Bicalutamide or nilutamide within 6 weeks prior to screening~ * Treatment with estramustine~ * Ketoconazole for treatment of prostate cancer~ * Treatment with abiraterone~* Radiation therapy for treatment of the prostate within 3 months prior to screening~* Radiation therapy for the treatment of metastases within 3 weeks (if single fraction of radiotherapy then within 2 weeks) and radionuclide therapy for the treatment of metastases within 4 weeks prior to screening~* Major surgery within 2 months prior to screening~* Known or suspected intracerebral disease or brain metastasis~* Use of an investigational agent within 4 weeks prior to treatment allocation or a period required by local regulation, whichever is longer~* Prior use, or participation in a clinical study, of an investigational agent that blocks androgen synthesis or targets the androgen receptor
