Sermonix Pharma Using Guardant Health CDx to Screen Breast Cancer Patients for Lasofoxifene Trial (Precision Oncology News)
"Sermonix Pharmaceuticals is starting a Phase III trial of endocrine therapy lasofoxifene for patients with locally advanced or metastatic ER+/HER2-breast cancer with an estrogen receptor 1 (ESR1) mutation, the company said on Thursday. Sermonix has partnered with Guardant Health for the trial and will use the Guardant360 CDx liquid biopsy assay, a blood-based sequencing test that detects mutations from circulating tumor DNA, to determine eligibility by screening patients for ESR1 variants. The trial, dubbed the ELAINE-3 study, will compare lasofoxifene against fulvestrant, an estrogen receptor antagonist, both in combination with Eli Lilly's CDK4/6 inhibitor Verzenio (abemaciclib)....Sermonix expects to dose the first patient for the trial in the first half of this year and plans to enroll 400 patients in total."
