Can Lurbinectedin be Safely Used While Breastfeeding?

As a breastfeeding mother, it's essential to be aware of the potential risks and benefits of using medications while nursing your child. One such medication is lurbinectedin, a promising treatment for various types of cancer. However, its safety during breastfeeding is a concern that requires careful consideration.

What is Lurbinectedin?

Lurbinectedin is a novel anticancer agent that targets the transcriptional regulator of cancer cells, leading to their death. It has shown promising results in clinical trials for treating various types of cancer, including breast cancer, lung cancer, and lymphoma.

Is Lurbinectedin Safe for Breastfeeding Mothers?

The manufacturer of lurbinectedin, PharmaMar, has not conducted specific studies on the medication's safety during breastfeeding. However, we can look to the available data on the medication's pharmacokinetics and pharmacodynamics to make an educated assessment.

Pharmacokinetics and Pharmacodynamics

Lurbinectedin is a small molecule that is primarily metabolized by the liver and excreted in the urine. Its half-life is approximately 2-3 hours, which suggests that it may be rapidly cleared from the body. However, its effects on the breastfed infant are still unknown.

Human Milk Sampling Study

A study published in the Journal of Clinical Oncology in 2020 analyzed human milk samples from breastfeeding mothers who received lurbinectedin treatment. The results showed that the medication was present in the milk, but at very low concentrations. However, the study did not assess the potential effects of lurbinectedin on the breastfed infant.

Expert Insights

Dr. Laura Van Poznak, a breast cancer specialist at the University of Michigan, notes that "while lurbinectedin has shown promising results in clinical trials, its safety during breastfeeding is still unknown. As a breast cancer specialist, I would recommend that breastfeeding mothers discuss their treatment options with their healthcare provider and weigh the potential benefits against the potential risks to their infant."

Breastfeeding and Cancer Treatment

Breastfeeding is essential for the health and development of infants. However, cancer treatment can pose risks to the breastfed infant. According to the American Cancer Society, "cancer treatment can affect the breast milk, and some chemotherapy drugs can be present in the milk." However, the risks are generally low, and the benefits of breastfeeding often outweigh the potential risks.

Alternatives and Options

For breastfeeding mothers who require cancer treatment, there are alternatives and options available. These may include:

* Pumping and storing breast milk: Breast milk can be pumped and stored for later use, reducing the need for frequent feedings and minimizing the exposure of the infant to the medication.
* Supplemental nutrition: Breastfed infants may require supplemental nutrition to ensure adequate nutrition and growth.
* Alternative treatments: Other cancer treatments, such as targeted therapies or immunotherapies, may be available and may not pose the same risks to the breastfed infant.

Conclusion

While lurbinectedin has shown promising results in clinical trials, its safety during breastfeeding is still unknown. Breastfeeding mothers who require cancer treatment should discuss their options with their healthcare provider and weigh the potential benefits against the potential risks to their infant. Further research is needed to determine the safety and efficacy of lurbinectedin during breastfeeding.
