Blocking stress and inflammation around surgery to slow ovarian cancer spread

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

Phase 2 Interventional Tel-Aviv Sourasky Medical Center · NCT06839144

This trial will try giving propranolol and etodolac around the time of debulking surgery to lower recurrence and boost immune responses in women with suspected high-grade ovarian cancer.

What this trial studies

This randomized, placebo-controlled Phase 2 trial enrolls 60 women undergoing primary or interval debulking for suspected high-grade ovarian epithelial cancer. Participants are randomized to perioperative propranolol plus etodolac or matching placebo, with propranolol started five days before surgery, increased on the day of surgery, and continued postoperatively at a fixed etodolac dose. Primary outcomes focus on feasibility measures—recruitment, drug safety, tolerability, and adherence—and on molecular tumor and blood changes; secondary outcomes include three-year recurrence rates. The design tests whether short-term blockade of beta-adrenergic and COX-2 signaling during the perioperative window can alter the tumor microenvironment and systemic immune responses linked to metastatic spread.

Who should consider this trial

Good fit: Women aged 20–85 with suspected high-grade ovarian epithelial cancer who are scheduled for primary or interval debulking surgery and can give informed consent are the intended participants.

Not a fit: Patients already on chronic beta-blockers or COX inhibitors, those with active asthma or allergy to the study drugs, or those not undergoing debulking surgery are unlikely to benefit from this perioperative intervention.

Why it matters

Potential benefit: If successful, the approach could reduce metastatic spread and lower recurrence after surgery by limiting surgery-triggered tumor promotion and improving anti-tumor immunity.

How similar studies have performed: Preclinical studies and some small clinical reports in other cancers have suggested benefit from perioperative beta-blockade plus COX-2 inhibition, but robust evidence in ovarian cancer is still limited.
