This study has been completed.
Information provided by (Responsible Party):
AEterna Zentaris Identifier:
First received: January 9, 2013

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Randomized Controlled Study Comparing AEZS-108 With Doxorubicin as Second Line Therapy for Locally Advanced, Recurrent or Metastatic Endometrial Cancer.

Further study details as provided by AEterna Zentaris:

Primary Outcome Measures:
  • Compare the overall survival (OS) of patients treated with AEZS-108 to the OS of patients treated with doxorubicin. [ Time Frame: 3 years ]

Secondary Outcome Measures:
  • Compare efficacy based on objective response rate (ORR). [ Time Frame: 3 years ]
  • Compare efficacy based on progression-free survival (PFS). [ Time Frame: 3 years ]
  • Compare efficacy based on clinical benefit rate (CBR). [ Time Frame: 3 years ]

Enrollment: 512
