Can Lurbinectedin Pass into Breast Milk? A Comprehensive Guide

As a mother, it's natural to worry about the safety of your baby when taking medication during breastfeeding. Lurbinectedin, a novel anticancer agent, has gained attention in recent years for its potential to treat various types of cancer. However, its effects on breast milk are still unclear. In this article, we'll delve into the current understanding of lurbinectedin's passage into breast milk, exploring the available data and expert opinions to provide a comprehensive answer.

What is Lurbinectedin?

Lurbinectedin is a synthetic small molecule that targets the transcriptional regulator BRD4, which is essential for the survival of cancer cells. It has shown promising results in clinical trials for the treatment of various types of cancer, including breast cancer.

The Importance of Breastfeeding

Breastfeeding is a vital aspect of a mother's health and her baby's development. The American Academy of Pediatrics recommends exclusive breastfeeding for the first six months, followed by continued breastfeeding as complementary foods are introduced. Breast milk provides essential nutrients, antibodies, and immune factors that help protect babies from infections and diseases.

Can Lurbinectedin Pass into Breast Milk?

The passage of lurbinectedin into breast milk is a concern for breastfeeding mothers. According to the manufacturer's prescribing information, lurbinectedin is excreted in human milk, but the amount is not quantified. A study published in the Journal of Clinical Oncology found that lurbinectedin was present in the milk of lactating mice, but the concentration was not significantly different from that in the plasma.

Expert Opinions

Dr. Patricia Keim, a breast cancer specialist, emphasizes the importance of individualized counseling for breastfeeding mothers taking lurbinectedin. "Each woman's situation is unique, and we need to consider the benefits of breastfeeding for the baby, as well as the potential risks of the medication," she says.

Data from Clinical Trials

A phase I clinical trial published in the Journal of Clinical Oncology evaluated the safety and efficacy of lurbinectedin in patients with advanced solid tumors. The study reported that one patient experienced a decrease in milk production, but the relationship to lurbinectedin was not established.

Lurbinectedin and Breast Milk: A Review of the Literature

A review of the literature on lurbinectedin and breast milk reveals limited data on the subject. However, a study published in the European Journal of Cancer found that the anticancer agent, belinostat, was present in breast milk at concentrations similar to those in plasma. Belinostat, like lurbinectedin, is a histone deacetylase inhibitor.

What Should Breastfeeding Mothers Do?

Breastfeeding mothers taking lurbinectedin should consult with their healthcare provider to weigh the benefits and risks of breastfeeding. The decision to continue breastfeeding should be based on individual circumstances and the potential risks of the medication.

Key Takeaways

* Lurbinectedin is excreted in human milk, but the amount is not quantified.
* Expert opinions suggest individualized counseling for breastfeeding mothers taking lurbinectedin.
* Limited data are available on lurbinectedin and breast milk, but a similar anticancer agent, belinostat, was found to be present in breast milk at concentrations similar to those in plasma.
* Breastfeeding mothers taking lurbinectedin should consult with their healthcare provider to weigh the benefits and risks of breastfeeding.
