About this study

Official title: Recombinant Human Prolactin for Lactation Induction in Adoptive Mothers

The purpose of the study is to assess the safety and determine the effects of the hormone prolactin on lactation (breast milk production).

Read the detailed description

Subjects will participate in a randomized, double-blind, placebo-controlled, crossover trial comparing breast pumping, alone, to breast pumping and r-hPRL. Subjects will have one week of instruction with the breast pump alone. Subsequently, subjects will receive 2 weeks of r-hPRL or placebo followed by 2 weeks of the alternate treatment.

Week 1: Study day 1, a baseline prolactin level will be obtained and subjects will be taught to use an electrical, hospital grade breast pump by a designated lactation consultant. Subjects will pump for 10 minutes at each breast. The total volume of milk will be recorded in a diary throughout the study. Prolactin levels will be obtained every 10 minutes for 60 minutes after pumping begins, then every 30 minutes for a total of 3 hours. Subjects will pump 3 times per day increasing to 8 times per day by the end of the first week and will continue this regimen throughout the study.

Week 2: One week after the initial visit, subjects will return to the GCRC for re-evaluation of the pumping technique and the first dose of medication. Subjects will pump for 10 minutes at each breast as on day 1 and prolactin levels will be obtained every 10 minutes for 60 minutes, then every 30 minutes for a total of 3 hours. At 3 hours, r-hPRL 60 mg/kg or placebo will be administered SC. Blood will be drawn every 10 minutes for 60 minutes, every 30 minutes for 2 hours, then at 4, 6 and 8 hours to obtain a peak prolactin level. Vital signs will be monitored every 15 minutes for the first hour, then every 2 hours for a total of 8 hours. Subjects will pump both breasts every 3 hours, starting after the r-hPRL or placebo injection. Subjects will be taught to give themselves SC injections and will administer their second dose of SC r-hPRL or placebo 12 hours after the first dose. Subjects will continue SC r-hPRL or placebo administration every 12 hours for the next 14 days. They will continue to pump daily, approximately every 3 hours, with a 5 hour break in the night to sleep. Subjects will be asked to refrigerate all milk and bring it in to GCRC visits for prolactin levels.

Subjects will return weekly for 4 additional visits (weeks 3, 4, 5, 6). At the weekly visits, blood will be drawn at baseline for a prolactin level and r-hPRL or placebo will be administered. Blood will then be drawn every 10 minutes for 60 minutes, then every 30 minutes for 2 hours, then every 2 hours for a total of 8 hours after the injection. Vital signs will be monitored as described above. At the week 4 visit, subjects will be switched to the alternate treatment for weeks 4 and 5. Subjects will be seen 14 days after their final injection. A baseline prolactin level will be drawn, then milk will be pumped, as previously. Blood will be drawn every 10 minutes for 60 minutes, then every 30 minutes for a total of 3 hours. A 1 cc sample of the milk will also be obtained 14 days after the final injection for analysis of composition. All side effects of r-hPRL will be recorded throughout the study. All milk obtained during the study will be stored and the milk composition will be determined before it is used. Infants receiving milk produced during the study will initially be monitored in the GCRC under the supervision of a neonatologist.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Recombinant human prolactin in people with Lactation, run by Massachusetts General Hospital at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 9 May 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Breast milk production (time frame: 28 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00181649, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 May 2013; AzTrials last refreshed its copy on 28 Oct 2026.
