Recurrent Ovarian Carcinoma Clinical Trial

Official title: Perfusion CT to Predict Progression-Free Survival and Response Rate in Bevacizumab Treatment of Platinum-Resistant Persistent or Recurrent Epithelial Ovarian, Fallopian Tube, or Peritoneal Carcinoma

Status Terminated

Clinical Trial Summary

This phase II trial studies how well computed tomography perfusion imaging works in predicting outcomes in patients with ovarian, fallopian tube, or primary peritoneal cancer who are receiving bevacizumab. Computed tomography perfusion imaging monitors the effects of the drug treatment on the blood flow to the tumor, and may help to predict whether a certain drug therapy is likely be successful in a patient with ovarian, fallopian tube, or primary peritoneal cancer.

Clinical Trial Description

PRIMARY OBJECTIVES:

I. To evaluate whether those patients with an increase in perfusion computed tomography (CT) tumor blood flow (BF) from T0 to T1 demonstrate poorer progression-free survival (PFS) compared to those patients with a decrease in BF from T0 to T1, among platinum-resistant, recurrent ovarian cancer patients treated with bevacizumab.

SECONDARY OBJECTIVES:

I. To evaluate whether change in perfusion CT tumor BF from T0 to T1, as a continuous variable, is associated with PFS.

II. To evaluate whether changes in perfusion CT tumor blood volume (BV) or permeability surface product area (PS) from T0 to T1 are associated with PFS.

III. To evaluate whether changes in perfusion CT tumor BF, BV, or PS from T0 to T1 are associated with response rate according to the standard anatomic response evaluation criteria (RECIST 1.1).

IV. To identify which combination of perfusion CT parameters, including tumor BF, BV, and PS, can serve to optimally distinguish patients in terms of PFS outcome.

V. To evaluate whether the association between change in perfusion CT parameters and treatment outcome (PFS or tumor response) is stable when analyzed with various commercially-available post-processing software.

TERTIARY OBJECTIVES:

I. In the subset of patients with multiple, eligible perfusion target lesions within the CT imaging volume, describe the variability of perfusion CT changes across different lesions within the same patient, and evaluate the impact of multiple target lesions on the association between change in perfusion CT parameters and PFS.

II. In a subset of patients, measure the reliability of perfusion CT parameters by analyzing the same perfusion imaging dataset using different readers and different post-processing software.

OUTLINE:

Patients undergo computed tomography perfusion imaging at baseline and on day 15 after initiation of standard of care bevacizumab treatment and before the second dose.

After completion of study, patients are followed up every 8 weeks for up to 18 months. ;
