Did you know that the overall pregnancy rate among women aged 15 to 44 declined by 12% between 2010 and 2019? According to the National Center for Health Statistics, the rate dropped from 97.3 per 1,000 to 85.6 per 1,000, highlighting the growing need for targeted interventions to support maternal and infant health.

For expectant mothers with autoimmune diseases, managing symptoms while ensuring a safe pregnancy can be challenging. Cimzia, a prescription medication used to treat rheumatoid arthritis, Crohn’s disease, and other inflammatory conditions, is sometimes considered during pregnancy. However, patients must be fully informed about its safety, precautions, and potential risks.

This article will explore Cimzia’s safety profile during pregnancy, including clinical evidence, possible risks, and alternative treatment options to help expectant mothers make informed decisions.

Key Takeaways

  • Cimzia is classified as a pregnancy Category B medication, indicating that animal studies have not shown risks to the fetus, making it a potentially viable option for expectant mothers with autoimmune diseases.
  • The drug’s low transfer rate through the placenta and minimal presence in breast milk suggest that it may be safe for use during pregnancy when managed appropriately.
  • Clinical data indicates that women with chronic inflammatory conditions on Cimzia can maintain better health during pregnancy, reducing the risk of complications for both mother and child.  
  • Despite the evidence supporting Cimzia’s safety, healthcare providers should carefully evaluate individual cases to ensure that the benefits of treatment outweigh the potential risks to the fetus.

Cimzia’s Category B Classification

The U.S. Food and Drug Administration (FDA) has approved Cimzia for treating rheumatoid arthritis, plaque psoriasis, Crohn’s disease, psoriatic arthritis, non-radiographic axial spondyloarthritis, and ankylosing spondylitis. This highlights Cimzia’s established safety and efficacy in managing chronic inflammatory conditions.

According to Goel & Stephens (2010), Cimzia (certolizumab pegol) is classified as a Pregnancy Category B drug. This designation means that animal studies have not shown harm to the fetus, but there are no well-controlled studies in pregnant women. While this classification suggests a low risk of fetal complications, further research is needed to fully establish Cimzia’s safety during pregnancy.

For pregnant women with autoimmune diseases, continuing Cimzia treatment can help prevent disease flare-ups that may pose risks to both mother and baby.

Weighing the Risks and Benefits

The FDA classifies Cimzia as a Pregnancy Category B drug. It may be used during pregnancy if the potential benefits outweigh the potential risks to the fetus. This classification is based on pharmacokinetic data showing low placental transfer and minimal presence in breast milk, making it a viable option for pregnant individuals with autoimmune diseases.

However, each patient should undergo a thorough risk-benefit assessment based on their medical condition. A comprehensive evaluation ensures that the benefits of Cimzia treatment outweigh any potential risks, supporting the best possible outcomes for both mother and child.

  • Cimzia’s Advantages: The primary benefit of using Cimzia during pregnancy is effective management of autoimmune conditions like rheumatoid arthritis, ankylosing spondylitis, and Crohn’s disease. Left untreated, these conditions can lead to serious complications for both the mother and fetus.
  • Cimzia’s Risks: While clinical studies show minimal transfer to breast milk, the lack of extensive pregnancy-specific research may raise concerns among some practitioners. The potential for unknown adverse effects on fetal development remains a consideration.

Healthcare providers must carefully evaluate the severity of the mother’s condition, Cimzia’s effectiveness in symptom management, and any possible risks to the fetus before proceeding with treatment.

Pregnancy Outcomes and Fetal Development

According to an article in 2018 from UCB via Practical Dermatology, the FDA has approved a label update for Cimzia. The update includes pharmacokinetic data showing negligible to low transfer through the placenta. There is also minimal transfer to the breast milk from mother to infant.

This update is particularly relevant, as approximately 17% of patients in the US with rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, and Crohn’s disease are women aged 18-45. Meanwhile, MotherToBaby shared that a review involving 14 pregnancies exposed to Cimzia found that all infants were born full-term and no infections were reported in the first six months after delivery.

These clinical studies and data reassure women with chronic inflammatory conditions who need Cimzia treatment during pregnancy. They emphasize the importance of maintaining disease control for both maternal and fetal health.

Alternative Treatments for Pregnant Women

Despite appropriate Cimzia dosing, administration, and proven safety for pregnant women, some individuals may still seek alternative treatments. Pregnant patients with autoimmune diseases have several alternative treatments for Cimzia. These alternatives include other biologic and non-biologic therapies. Corticosteroids, such as prednisone, also offer an option for managing autoimmune diseases during pregnancy.

These medications effectively control inflammation and disease activity. However, they should be used at the lowest effective dose to minimize potential risks to the fetus. Medical professionals must carefully evaluate each patient’s condition. They must also weigh the benefits and risks of these alternative treatments to ensure the best outcomes for both mother and fetus.

Conclusion

Given the FDA’s Category B classification of Cimzia, the medication offers a treatment option for expectant mothers managing autoimmune diseases. This classification signals that the medication hasn’t shown risks in animal studies and has minimal transfer to breast milk, reassuring those concerned about its impact during pregnancy. 

However, healthcare providers must conduct thorough assessments of each patient’s individual circumstances. This evaluation should weigh the benefits of Cimzia against any potential risks, ensuring appropriate care decisions that prioritize the well-being of both mother and child.
