Inhibiting Beta-adrenergic and COX-2 Signaling During the Perioperative Period to Reduce Ovarian Cancer Progression (OC-POP-PT)

July 8, 2025 updated by: Tel-Aviv Sourasky Medical Center

Inhibiting Beta-adrenergic and COX-2 Signaling During the Perioperative Period to Reduce Ovarian Cancer Progression: A Randomized Placebo-Controlled Clinical Trial

This study investigates the impact of perioperative inhibition of beta-adrenergic and COX-2 signaling in ovarian cancer patients undergoing debulking surgery. The trial aims to assess the feasibility, safety, and biological effects of a combination of propranolol and etodolac in reducing cancer metastasis and improving immune responses.

Study Overview

Detailed Description

The study is a placebo-controlled randomized clinical trial (RCT) enrolling 60 women undergoing ovarian cancer debulking surgery. Participants will be assigned to receive propranolol (starting 5 days preoperatively, increased on the day of surgery, and continued postoperatively) and etodolac at a fixed dose. The primary outcomes include recruitment rate, drug safety, tolerability, adherence, and molecular tumor and blood characteristics. Secondary outcomes include 3-year recurrence rates.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Transcriptional Activity in Excised Tumors
Time Frame: At the time of surgery (Day 0). Data will be reported through study completion, an average of 2 years.
Transcriptional activity related to pro-metastatic (e.g., EMT), pro-growth (STAT and GATA families), and stress and inflammatory signaling (NF-κB/cRel, AP-1, CREB, GR) in excised tumors.
At the time of surgery (Day 0). Data will be reported through study completion, an average of 2 years.
Transcriptional Activity in Blood Samples
Time Frame: Preoperative baseline (Informed consent day), Day 0 (surgery), postoperative Day 1, Week 3, and Week 11. Data will be reported through study completion, an average of 2 years.
Longitudinal analysis of transcriptional activity in peripheral blood, focusing on stress/inflammatory pathways (NF-κB/cRel, AP-1, CREB, GR). Unit of measure: Relative expression levels (fold change).
Preoperative baseline (Informed consent day), Day 0 (surgery), postoperative Day 1, Week 3, and Week 11. Data will be reported through study completion, an average of 2 years.
Adverse Event Assessment
Time Frame: From 5 days pre-surgery to 3 months post-surgery.
