Why Are Radius Health Shares Soaring Today?

  • The Menarini Group and Radius Health Inc RDUS have announced topline results from the EMERALD Phase 3 study evaluating elacestrant as second- or third-line monotherapy in ER+/HER2- advanced/metastatic breast cancer patients.
  • There were two primary endpoints: progression-free survival (PFS) in the overall population and PFS in patients with tumors harboring estrogen receptor 1 (ESR1) mutations.
  • EMERALD met both primary endpoints, showing statistically significant PFS. 
  • The safety profile of elacestrant exhibited in EMERALD was similar to that of the previous clinical trial. 
  • Menarini and Radius plan on proceeding with regulatory submissions in both the U.S. and European Union in 2022.
  • Elacestrant is a selective estrogen receptor degrader (SERD). Overall, 466 patients were enrolled in the study, including 220 (47%) with tumors harboring an Estrogen Receptor 1 (ESR1) mutation. 
  • A complete evaluation of the data is ongoing. Current plans are to present those results at the upcoming San Antonio Breast Cancer Symposium in December 2021 and publish them in a peer-reviewed journal.
  • Price Action: RDUS shares are up 33% at $20.57 during the premarket session on the last check Wednesday.
