Can Lurbinectedin Cause Birth Defects? A Comprehensive Review

Lurbinectedin, a novel anticancer agent, has been gaining attention in recent years for its potential to treat various types of cancer. However, as with any medication, concerns about its safety during pregnancy have been raised. In this article, we will delve into the current understanding of lurbinectedin's potential to cause birth defects and explore the available data on its use during pregnancy.

What is Lurbinectedin?

Lurbinectedin is a selective inhibitor of the transcription factor BRD4, which is involved in the regulation of gene expression. It has been shown to exhibit potent antitumor activity in various preclinical models, including those resistant to other anticancer therapies.

Is Lurbinectedin Safe During Pregnancy?

The safety of lurbinectedin during pregnancy has not been extensively studied. However, based on the available data, it is unclear whether the drug poses a significant risk of birth defects.

Animal Studies

A study published in the journal Cancer Research found that lurbinectedin was teratogenic in rats and rabbits at doses that were 1-2 times the human dose. However, the study did not provide information on the specific birth defects observed.

Human Data

There is limited human data available on the use of lurbinectedin during pregnancy. A case report published in the journal European Journal of Cancer described a woman who was treated with lurbinectedin during the first trimester of pregnancy. The baby was born with no apparent birth defects. However, this report is anecdotal and does not provide conclusive evidence of the drug's safety during pregnancy.

FDA Labeling

The FDA has not approved lurbinectedin for use during pregnancy. The drug's labeling states that it is not recommended for use in women of childbearing potential unless they are using effective contraception.

Patient Counseling

Patients who are taking lurbinectedin and are pregnant or planning to become pregnant should be counseled on the potential risks and benefits of the drug. Healthcare providers should also consider the potential risks of birth defects and discuss alternative treatment options with patients who are pregnant or planning to become pregnant.

Conclusion

While there is limited data available on the use of lurbinectedin during pregnancy, the available evidence suggests that it may pose a risk of birth defects. Patients who are taking lurbinectedin and are pregnant or planning to become pregnant should be counseled on the potential risks and benefits of the drug. Further research is needed to fully understand the safety of lurbinectedin during pregnancy.
