eLISTA: Cabergoline for Lactation Inhibition After Early Second-Trimester Abortion or Pregnancy Loss
Study Details
Study Description
Brief Summary
Breast pain following second-trimester abortion is common. Breast engorgement and milk leakage following second-trimester perinatal loss and abortion can cause both physical pain and emotional distress. Dopamine agonists have previously been shown to be effective in lactation inhibition for third-trimester fetal/neonatal loss or contraindications to breastfeeding. The investigator's prior work demonstrated that compared to placebo, a single dose of cabergoline was effective in preventing breast symptoms after abortion or loss 18-28 weeks. As lactogenesis starts as early as 16 weeks gestation, the investigators hope to determine the efficacy of cabergoline earlier in the second trimester,16-20 weeks.

Detailed Description
This study is a double-blinded, placebo-controlled, gestational-age stratified superiority trial of those undergoing abortion or intrauterine fetal demise between 16 and 20-weeks gestation at Stanford Health Care. Participants will be randomized to either cabergoline 1 mg or placebo the day of procedure. Participants will complete a survey to assess symptoms, using the validated Bristol Breast Symptoms Inventory, and side-effects at baseline and Day 2, 4, 7, and 14 after the procedure. The study plan is to recruit 72 subjects powered to detect a 45% decrease in those reporting breast symptoms compared to the control group.
This study has the potential to improve overall patient experience by validating the routine use of cabergoline for lactation inhibition in the early second-trimester after abortion or pregnancy loss.

Outcome Measures
Primary Outcome Measures
- Number of Participants Reporting Breast Pain [Day 4 after procedure]
Participants will assess their breast symptoms using the validated Bristol Breast Inventory survey to assess 4 domains of breast symptoms: tenderness, engorgement, leaking milk, pain relief. Participants who indicated symptoms in any of these areas met the criteria for this outcome.
Secondary Outcome Measures
- Number of Participants Experiencing Side-effects [Cumulative over 2 weeks]
Participants selected from previously documented side-effects from the dopaminergic class or entered as free-text. Participants may have reported more than one side-effect.
- Number of Participants Reporting Significant Bother From Breast Pain [Day 4 after procedure]
Assessed using a Facial Pain Score (scale range 0-6, significant bother >=4)
- Number of Participants Reporting Significant Bother From Side-effects [Cumulative over 2 weeks]
Assessed using a Facial Pain Score (scale range 0-6, significant bother >=4)
