DPYD Safety Update: Enhancing Patient Safety through Genetic Testing

In a significant development for patient safety in oncology, the Food and Drug Administration (FDA) has mandated genetic testing for patients undergoing treatment with capecitabine (Xeloda®), a commonly used chemotherapy drug. This directive aims to mitigate the risks associated with severe and potentially fatal side effects stemming from a genetic variant known as DPYD. As oncologists and pharmacy professionals begin to navigate this new landscape, solutions provided by companies like Aranscia are stepping in to facilitate compliance and improve patient outcomes.

Understanding the Risk

Recent discussions among oncology specialists, particularly following the FDA's updated warning label on capecitabine, have underscored a pressing concern: between 3% and 8% of the general populace possesses a variant in the DPYD gene that hampers their body's ability to metabolize certain chemotherapy drugs effectively. This variant results in a deficiency of dihydropyrimidine dehydrogenase (DPD), the enzyme responsible for breaking down capecitabine and fluorouracil. Consequently, patients with this deficiency may face a heightened risk of toxic reactions or even death if not properly identified through genetic testing prior to treatment.

The updated FDA warning specifies that healthcare providers must evaluate the genetic risks associated with patients before administering capecitabine. The stark
