As of August 2019, there have been 870 enrolled patients, with 30 screen failures, resulting in 792 remaining patients in the study, as seen in figure 1. Unfortunately, the accrual is slower than predicted, as seen in figure 2. The number of enrolled patients per country is shown in table 1, and the basic demographic and clinical data of the accrued patients so far is demonstrated in table 2.

Table 2–Basic demographic and clinical data of the accrued patients so far:
Up to August 2019, there have been 2287 completed PROMs questionnaires, and 735 biospecimens have been collected at baseline with an 84% compliance rate.
Future directions for this interesting study will include developments in several directions:
- Imaging- There is great interest from the study investigators and industry collaborators to collect archival imaging for all patients at baseline and at disease progression. Currently, this is not being done and the only thing being collected is whether an assessment of metastatic disease was done. The investigators believe it is critical to obtain the actual raw imaging scans, so these can be compared, monitored and learned from.
- Biospecimens– Investigators are interested in the selection of a cfDNA assay platform
- Protocol updates– The fifth amendment of the protocol is scheduled to be released at the end of 2019 or early 2020
The goal is to significantly expand the study internationally to various regions in the world. The plan is to create a significant repository of clinical, biospecimen-derived, and PROM-derived database of patients with advanced prostate cancer. The investigators aim to explore all aspects of treatment and symptoms of these patients. Moreover, understanding how physicians all over the world treat these patients, and why they decide to change treatment is a critical goal of this impressive project. The are many working groups and sub-studies that are undergoing in an attempt to explore new relevant horizons
