Trial Information

A Phase II Trial of AMG 386 (IND# ), a Selective Angiopoietin ½ Neutralizing Peptibody, in Patients With Persistent/Recurrent Carcinoma of the Endometrium



- To estimate the proportion of patients with persistent or recurrent endometrial cancer,
who survive progression-free for at least 6 months and the proportion of patients who
have objective tumor response (complete or partial), treated with angiopoietin
1/2-neutralizing peptibody AMG 386 (AMG 386).

- To assess the frequency of objective tumor response in patients treated with this

- To determine the nature and degree of toxicity of this regimen in these patients.


- To determine the duration of progression-free survival and overall survival of patients
treated with this regimen.

OUTLINE: This is a multicenter study.

Patients receive angiopoietin 1/2-neutralizing peptibody AMG 386 IV over 30-60 minutes on
days 1, 8, 15, and 21. Courses repeat every 28 days in the absence of disease progression or
unacceptable toxicity.

After completion of study therapy, patients are followed up every 3 months for 2 years and
then every 6 months for 3 years.
