A Study of Letrozole in the Treatment of Endometrial Cancer

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00333086
Recruitment Status : Completed

Information provided by (Responsible Party):
Novartis ( Novartis Pharmaceuticals )

Brief Summary:
Currently available treatments for endometrial cancer are associated with limited efficacy and significant toxicity. This study will assess the safety and efficacy of letrozole, an aromatase inhibitor, on endometrial cancer.

Condition or disease Intervention/treatment Phase
Recurrent and Metastatic Endometrial Cancer Drug: Letrozole Phase 2

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 36 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)

Drug Information available for: Letrozole

Primary Outcome Measures :
  1. Response rates (complete response, partial response, no change, progressive disease) measured by tumor marker assessments and radiologic imaging at week 12 then every 12 weeks x 1 year followed by every 16 weeks

Secondary Outcome Measures :
  1. Duration of clinical response, time to progression of the disease, correlation of tumor response with pretreatment ER/PR status, histological grade and aromatase levels
