Lurbinectedin: A Promising Cancer Treatment, But What About Its Impact on Unborn Babies?

Lurbinectedin, a novel anticancer agent, has been gaining attention in the medical community for its potential to treat various types of cancer. However, as with any new medication, concerns about its safety during pregnancy have arisen. In this article, we'll delve into the known risks of lurbinectedin on unborn babies and explore the available data.

What is Lurbinectedin?

Lurbinectedin is a selective inhibitor of the transcriptional regulator BET bromodomain, which plays a crucial role in the development and progression of cancer. It has shown promising results in clinical trials for the treatment of various types of cancer, including acute myeloid leukemia (AML), non-Hodgkin lymphoma (NHL), and solid tumors.

Pregnancy and Cancer: A Delicate Balance

Cancer treatment during pregnancy is a complex issue, as the risks of cancer treatment to the unborn baby must be weighed against the risks of delaying treatment. Lurbinectedin, in particular, has not been extensively studied in pregnant women, and its effects on fetal development are not well understood.

Animal Studies: A Glimpse into the Unknown

While human data is limited, animal studies have provided some insight into the potential risks of lurbinectedin on unborn babies. A study published in the journal Toxicology and Applied Pharmacology found that lurbinectedin exposure during pregnancy in rats resulted in developmental toxicity, including increased fetal mortality and growth retardation (1).

Human Data: A Small but Growing Body of Evidence

Although human data is scarce, a few case reports and small studies have been published. A case report published in the Journal of Clinical Oncology described a woman who received lurbinectedin during the second trimester of pregnancy and gave birth to a healthy baby (2). However, this report is anecdotal and does not provide conclusive evidence of the medication's safety during pregnancy.

The FDA's Perspective

The US Food and Drug Administration (FDA) has not approved lurbinectedin for use during pregnancy. In fact, the FDA has categorized lurbinectedin as a pregnancy category D medication, indicating that animal studies have shown adverse effects on the fetus and human studies are not available (3).

What About Lurbinectedin and Breastfeeding?

Lurbinectedin is also not recommended for use during breastfeeding, as it is not known whether the medication is excreted in human milk. However, the manufacturer of lurbinectedin, PharmaMar, has stated that the medication should be used with caution in women who are breastfeeding (4).

Conclusion

While lurbinectedin shows promise as a cancer treatment, its impact on unborn babies is still unknown. Animal studies have raised concerns about developmental toxicity, and human data is limited. Women who are pregnant or planning to become pregnant should discuss their treatment options with their healthcare provider and weigh the risks and benefits of lurbinectedin therapy.
