  Purpose
Medications used to increase breast milk production increase prolactin secretion, the main hormone of lactation. There are no FDA approved medications used to improve breast feeding, but metoclopramide is used off-label and can have intolerable side effects. We examined the biological activity and safety of recombinant human prolactin (r-hPRL) as a potential medication to augment lactation. In this study, the effect of r-hPRL on breast milk production in women who did not recently deliver a baby and its effect on the bones and menstrual cycle were tested.

Primary Outcome Measures:
  • Galactorrhea [ Time Frame: 7 days ]
    Galactorrhea is breast milk production.


Secondary Outcome Measures:
  • Bone Turnover-deoxypyridinoline, N-telopeptide, Bone Specific Alkaline Phosphatase [ Time Frame: 7 days ]
  • Menstrual Cycle Length [ Time Frame: 28 days ]
  • Reproductive Hormones-LH, FSH, Estradiol [ Time Frame: 7 days ]

Enrollment: 21
Study Start Date: April 2002
Study Completion Date: March 2011
Primary Completion Date: March 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: recombinant human prolactin
Recombinant Human Prolactin 60 mcg/kg once daily subcutaneous injection
Drug: Recombinant Human Prolactin
Placebo Comparator: Placebo
Normal saline placebo subcutaneous injection
Drug: Recombinant Human Prolactin

Detailed Description:
There are no FDA approved medications in the U.S. to augment lactation. Metoclopramide is used off-label but can have intolerable side effects. We examined the biological activity and safety of recombinant human prolactin (r-hPRL) as preliminary data for its use to augment lactation. Healthy, non-postpartum women (n=21) with regular menstrual cycles underwent a 7 day randomized, double-blind, placebo-controlled trial of r-hPRL. Galactorrhea, markers of bone turnover, calcium homeostasis and gonadal function were measured and side effects recorded.
