Hormone Sensitive Prostate Cancer Patients Switched to Degarelix Therapy After Failing on GnRH Agonists: A Prospective, Observational, Phase IV Study (DELAY)

Detailed Summary

This Phase IV observational trial is intended to identify patients who are failing GnRH agonist therapy as evidenced by a rising PSA and who have yet to initiate secondary manoeuvres involving antiandrogens. This group may include both non-metastatic as well as metastatic patients. The trial will determine if these patients will benefit from switching to Degarelix. It will assess the effect of Degarelix's direct mode of action on androgen levels and whether continuous use of Degarelix improves disease progression. As per the CUA Guidelines for the Management of CRPC, because the androgen receptor remains active in most patients who have developed castration resistant disease, it is recommended that ADT should be continued (LEVEL 3, GRADE C). Therefore, it is logical to continue patients on Degarelix throughout the castrate resistant period. This will allow for the gathering of data that is currently unknown within this setting, such as the effect of combined treatment with antiandrogens as well as chemotherapy and other castrate resistant treatments.
