Phase 3 Interventional Chinese University of Hong Kong · NCT03902912

This study is testing if taking prednisolone can help women who have had multiple miscarriages by looking at how it affects certain immune cells in their uterus.

What this trial studies

This study aims to explore the impact of prednisolone, a glucocorticoid, on uterine natural killer (uNK) cells in women who have experienced recurrent miscarriages. Participants will receive an oral dose of 10 mg/day of prednisolone and will undergo endometrial biopsies at an outpatient clinic to assess the treatment's effects. The study seeks to clarify the inconclusive evidence surrounding prednisolone as a potential therapy for recurrent miscarriage and to understand the underlying mechanisms involved.

Who should consider this trial

Good fit: Ideal candidates are women under 40 years old with a history of three or more consecutive miscarriages.

Not a fit: Patients with allergies to prednisolone or specific uterine anomalies, as well as those with certain medical conditions like antiphospholipid syndrome or diabetes, may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could improve pregnancy outcomes for women with a history of recurrent miscarriages.

How similar studies have performed: While the evidence for prednisolone treatment in this context is inconclusive, similar studies have explored its effects, indicating a need for further investigation.
