Study To Assess Renewal Of Treatment In Patients Recently Diagnosed With Prostate Cancer (CHRONOS3)

July 24, 2019 updated by: Ipsen

A Non-interventional, Multi-centric, Observational, Prospective Study to Collect the Criteria on Which Renewal of GnRH Analogue Treatment With Triptorelin (Diphereline 3.75mg or Diphereline pr 11.25mg) is Made in Patients Recently Diagnosed With Prostate Cancer Requiring Androgen Deprivation Therapy

The purpose of this study is to collect some parameters which may help to provide guidance on how Androgen Deprivation Therapy (ADT) drugs are renewed and physician satisfaction.
