- NCT00327444
- Lead Sponsor
- Sanofi
- Brief Summary
This study was designed to characterize the effect of aflibercept in participants with advanced chemoresistant ovarian cancer.
Primary objective: Compare the effect of aflibercept (ziv-aflibercept, AVE0005, VEGF trap, ZALTRAP®) to placebo treatment on repeat paracentesis in symptomatic malignant ascites in participants with advanced ovarian cancer
Secondary objectives: Safety, tolerability, paracentesis-related parameters, participant-reported outcome.
- Detailed Description
The study included:
* A Thirty (30)-day screening phase
* The double blind treatment period for a minimum of 60 days. Day 1 of the double-blind treatment period was defined as the date of the qualifying paracentesis (ie, withdrawal of \>= 1 Liter of ascitic fluid). Participants were randomized after adequate recovery from the qualifying paracentesis (The first dose was administered on Day 1 or Day 2).
* The optional open-label extension (until treatment discontinuation criteria were met)
* A posttreatment follow-up phase lasting 60 days.
Criteria for discontinuation included:
1. Participant or his legally authorized representative request discontinuation
2. In the Investigator's opinion, continuation of treatment would be detrimental to the participant's well being, such as disease progression, unacceptable toxicity, noncompliance, or logistical considerations
3. Sponsor request
4. Intercurrent illness that prevented further administration of investigational product(IP)
5. More than 2 IP dose reductions
6. Unacceptable adverse events (AE) not manageable by symptomatic therapy, dose delay, or dose modification
7. Arterial thromboembolic events, including cerebrovascular accidents, myocardial infarctions, transient ischemic attacks, new onset or worsening of preexisting angina
8. Radiographic evidence of intestinal obstruction (for example, dilated loops of bowel accompanied by air-fluid levels) or gastrointestinal perforation (for example, presence of extraluminal gas) requiring surgical intervention

Group Intervention Description Placebo aflibercept (ziv-aflibercept, AVE0005, VEGF trap, ZALTRAP®) Participants with advanced ovarian cancer administered placebo in the double-blind (DB) period. In the open-label (OL) period, participants had the option to receive aflibercept or be withdrawn from the study. Aflibercept aflibercept (ziv-aflibercept, AVE0005, VEGF trap, ZALTRAP®) Participants with advanced ovarian cancer administered aflibercept in the double-blind (DB) period. In the open-label (OL) period, participants had the option to continue to receive aflibercept or be withdrawn from the study. Placebo Placebo Participants with advanced ovarian cancer administered placebo in the double-blind (DB) period. In the open-label (OL) period, participants had the option to receive aflibercept or be withdrawn from the study.
- Primary Outcome Measures
Name Time Method Time to Repeat Paracentesis (TRP) From Day 1 up to 6 months from randomization TRP was defined as the number of days between the date of randomization and the date of the first post-randomization paracentesis.
For participants who did not undergo a postrandomization paracentesis on study, TRP was calculated from randomization to the end of the double-blind treatment period.
- Secondary Outcome Measures
Name Time Method Area Under the Curve (AUC) for Participant Assessed Ascites Impact Measure (AIM) From Day 1 up to 60 days from randomization to the first postrandomization paracentesis AIM 4 symptoms (abdominal discomfort, abdominal bloating, abdominal pain, and ability to move normally) are scored from 0 to 5, where higher scores represent worst outcomes. An AIM total score ranges from 0-20.
A plot for (The AIM questionnaire total score - Baseline score) versus time were generated. AIM AUC represents the overall improvement (scored positive) if the area is below the baseline value or worsening (scored negative) if the area is above the baseline. AIM AUC for a participant is the sum of individual areas representing improvement (+) or worsening (-).60-Day Frequency of Paracentesis (FOP) From Day 1 up to 60 days from randomization 60-Day FOP was defined as the total number of paracenteses performed within the first 60 days after randomization during the double blind treatment period.
Plasma Levels of Free and VEGF-bound Aflibercept Following every biweekly treatment administration up to 60 days after treatment discontinuation Free aflibercept and VEGF-bound aflibercept plasma concentrations were measured by separate enzyme-linked immunosorbent assay (ELISA). The limit of quantitation of free aflibercept was 15.6 ng/mL, and of VEGF-bound aflibercept was 43.9 ng/mL.
Peak free aflibercept was estimated at the end of Cycle 1 (C1) administration. The median free and VEGF-bound trough concentrations were determined for each participant beyond Cycle 3 (C3), then mean values were estimated from these median values.
