Cabergoline plus coasting to reduce ovarian hyperstimulation syndrome

Clinical Study to Evaluate Efficacy of Cabergoline to Coasting in Reducing the Incidence of Ovarian Hyperstimulation Syndrome

PHASE2 · Tanta University · NCT07043322

This test checks whether adding cabergoline to coasting lowers the chance of ovarian hyperstimulation syndrome in women at high risk during gonadotropin ovarian stimulation.

What this trial studies

This Phase 2 interventional study enrolls women at high risk for OHSS who are undergoing controlled ovarian stimulation with a long luteal protocol. Participants will undergo standard coasting and some will also receive cabergoline, with clinicians monitoring follicle growth, estradiol levels, and clinical signs of OHSS. The main outcome is the incidence and severity of OHSS, with safety and adverse events tracked throughout stimulation and the peri-trigger period. The protocol excludes patients with major uncontrolled medical conditions or known allergy to cabergoline.

Who should consider this trial

Good fit: Women aged 18–38 with BMI under 30 using a long luteal gonadotropin stimulation protocol who meet high-risk criteria for OHSS (more than 20 follicles >12 mm and/or estradiol >3000 pg/ml when the leading follicle is >15 mm) and have Day 2 FSH <10 mIU/L and E2 <50 pg/ml.

Not a fit: Patients with uncontrolled chronic diseases (severe liver, kidney, cardiac disease, uncontrolled hypertension or diabetes), known allergy to cabergoline, BMI ≥30, or outside the 18–38 age range are unlikely to qualify or benefit.

Why it matters

Potential benefit: If successful, this approach could reduce the risk and severity of OHSS, lowering complications and the need for hospitalization during fertility treatment.

How similar studies have performed: Previous studies have shown cabergoline can modestly reduce OHSS risk and coasting is an established prevention method, so combining them has some supportive but not definitive evidence.
