The purpose of this study is to determine whether cabergoline is effective in reducing the incidence and severity of Ovarian Hyperstimulation Syndrome (OHSS), especially for severe cases; and to derive biomarkers for the risk of developing OHSS.

Condition Intervention Phase

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: A Randomised Controlled Trial of Cabergoline Prophylaxis for Ovarian Hyperstimulation Syndrome in IVF Cycles and Derivation of Biomarkers for OHSS.

Primary Outcome Measures:
  • The development of moderate or severe OHSS necessitating admission for management of OHSS. [ Time Frame: Within 2 weeks after hCG trigger ]

Secondary Outcome Measures:
  • The need for abdominal or pleural tap [ Time Frame: Within 3 weeks after hCG trigger ]
  • Other complications of OHSS (venous thromboembolism, cardiac failure, renal failure, acute respiratory failure, pulmonary oedema and coma) [ Time Frame: Within 3 weeks after hCG trigger ]
  • Admission into intensive care [ Time Frame: Within 3 weeks after hCG trigger ]
  • Examination of potential biomarkers for OHSS [ Time Frame: 1-2 years ]

Estimated Enrollment: 540

Arms Assigned Interventions

Placebo Comparator: Placebo Drug: Placebo
1 tablet daily for 8 days.

Detailed Description:

Severe ovarian hyperstimulation syndrome (OHSS) occurs in up to 2% of in-vitro fertilisation (IVF) cycles, resulting in accumulation of fluid in peritoneal, pleural and pericardial cavities, haemo-concentration with resultant venous thromboembolic phenomena, reduced perfusion of vital organs, renal failure, acute respiratory failure, and even death.

The long term aim is to develop a comprehensive strategy in reducing the incidence and severity of OHSS in in-vitro fertilisation (IVF) cycles. Our short term aim (2-3 years) is to test the ability of the dopamine receptor agonist cabergoline in reducing the incidence and severity of OHSS in high risk women undergoing controlled ovarian hyperstimulation (COH) in fresh IVF cycles through a reduction in vasoactive cytokine levels, specifically in serum vascular-endothelial growth factor (VEGF).

Specifically we will:

  1. Conduct a randomised double-blind placebo-controlled trial in women at high risk of developing OHSS during a fresh COH-IVF cycle
  2. Investigate the serum and follicular fluid levels for potential biomarkers of OHSS.

Ages Eligible for Study:   21 Years to 45 Years   (Adult)
