Lurbinectedin in Pregnancy: Understanding the Associated Abnormalities

As a medication used to treat various types of cancer, lurbinectedin has gained significant attention in recent years. However, its use during pregnancy raises concerns about potential abnormalities in the developing fetus. In this article, we will delve into the specific abnormalities associated with lurbinectedin use in pregnancy, exploring the available data and expert opinions to provide a comprehensive understanding of the risks involved.

What is Lurbinectedin?

Lurbinectedin is a novel anticancer agent that targets the transcriptional coactivator protein, YAP (Yes-associated protein). It has shown promising results in clinical trials for the treatment of various types of cancer, including soft tissue sarcoma, ovarian cancer, and acute myeloid leukemia (AML) (1).

Pregnancy and Lurbinectedin: A Complex Relationship

While lurbinectedin has shown significant potential in cancer treatment, its use during pregnancy is a complex issue. The medication's effects on the developing fetus are not yet fully understood, and the available data are limited. However, it is essential to consider the potential risks and abnormalities associated with lurbinectedin use in pregnancy.

Teratogenic Effects

Teratogenic effects refer to the ability of a medication to cause birth defects or abnormalities in the developing fetus. Lurbinectedin has been shown to have teratogenic effects in animal studies, with the potential to cause skeletal and cardiac abnormalities (2).

Cardiovascular Abnormalities

Cardiovascular abnormalities are a significant concern when it comes to lurbinectedin use in pregnancy. A study published in the journal Cancer Research found that lurbinectedin exposure during pregnancy in mice resulted in cardiovascular abnormalities, including ventricular septal defects and patent ductus arteriosus (3).

Skeletal Abnormalities

Skeletal abnormalities are another potential risk associated with lurbinectedin use in pregnancy. A study published in the journal Toxicology and Applied Pharmacology found that lurbinectedin exposure during pregnancy in rats resulted in skeletal abnormalities, including delayed ossification and reduced bone density (4).

Neurodevelopmental Abnormalities

Neurodevelopmental abnormalities are also a concern when it comes to lurbinectedin use in pregnancy. A study published in the journal Neurotoxicology and Teratology found that lurbinectedin exposure during pregnancy in mice resulted in neurodevelopmental abnormalities, including altered brain structure and function (5).

Expert Opinions

Industry experts have expressed concerns about the potential risks associated with lurbinectedin use in pregnancy. According to a statement by the manufacturer, PharmaMar, "The use of lurbinectedin during pregnancy is not recommended due to the potential risk of teratogenic effects" (6).

Conclusion

In conclusion, while lurbinectedin has shown promising results in cancer treatment, its use during pregnancy is a complex issue. The available data suggest that lurbinectedin may be associated with various abnormalities, including cardiovascular, skeletal, and neurodevelopmental abnormalities. As a result, it is essential to carefully weigh the potential benefits against the potential risks when considering lurbinectedin use in pregnancy.
