New solution helps guide cancer therapy selection and dosing strategies to support safer, more effective patient care

FoundationOne PGx includes genes associated with the metabolism of medicines that have strong clinical evidence and actionable guidelines, including DPYD

BOSTON & EL MONTE, Calif.--(BUSINESS WIRE)--May 4, 2026-- Foundation Medicine, Inc., a global, patient-focused precision medicine company, today announced plans to launch FoundationOne^®PGx, a pharmacogenetic (PGx) offering to identify genetic differences that influence how medicines are metabolized and processed by the body. FoundationOne PGx will be offered in the United States through a partnership with Fulgent Genetics, Inc. (NASDAQ: FLGT) and will be available to order through the Foundation Medicine portal.

Based on their genetics, patients may metabolize medicines more slowly or more rapidly than expected, which can increase the risk of adverse drug reactions and impact treatment effectiveness. PGx testing helps inform how a patient will process certain medications. It may be ordered early in the disease course to help healthcare providers better understand the potential pharmacogenetic effects of therapies and reduce the risk of adverse drug reactions, or later, in advanced disease—particularly when patients are receiving combination regimens, including chemotherapies.

FoundationOne PGx’s current oncology-relevant panel includes genes associated with the metabolism of medicines that have strong clinical evidence and actionable guidelines, including: CYP2C19, CYP2C9, CYP2D6, DPYD, G6PD, NUDT15, TPMT, UGT1A1 and UGT1A4. Genetic variants in these genes can influence patient response to chemotherapies, targeted therapies and supportive care medications commonly used in oncology.

“FoundationOne PGx is an important addition to our portfolio, helping healthcare providers anticipate potential toxicity of medicines, reduced treatment effectiveness, and increased risk of adverse reactions,” said Todd Druley, M.D., Ph.D., Chief Medical Officer at Foundation Medicine. “When combined with our high-quality comprehensive genomic profiling tests, this PGx offering powered by Fulgent can help healthcare providers build a more comprehensive understanding of each patient’s genomic profile to inform treatment decisions throughout their care.”

“We are excited to expand our partnership with Foundation Medicine, and collectively launch this new service aimed at improving patient care in oncology,” said Brandon Perthuis, Chief Commercial Officer at Fulgent. “This is perfect timing with the recent guideline updates and professional society positionssignaling a clear shift toward proactive integration of PGx testing into routine oncology care. We look forward to working collaboratively to ensure patients have access to this important testing.”
