The ELECTRA and ELEVATE studies were designed to overcome different resistance mechanisms and improve patient outcomes with oral-oral combination options. Updated results from the ELECTRA study, evaluating elacestrant in combination with abemaciclib regardless of metastatic site, show a safety pro with previous results. Recommended phase 2 dose for this combination is presented. Updated analysis from the ELEVATE study demonstrates that all evaluable elacestrant plus targeted therapy combination arms are consistent with the known safety profiles of everolimus, alpelisib, ribociclib and palbociclib plus standard of care endocrine therapy. Recommended phase 2 dose for the combination of elacestrant and everolimus is presented. FLORENCE, Italy & NEW YORK--(BUSINESS WIRE)-- The Menarini Group (“Menarini”), a leading international pharmaceutical and diagnostics company, and Stemline Therapeutics, Inc. (“Stemline”), a wholly-owned subsidiary of the Menarini Group, focused on bringing transformational oncology treatments to cancer patients, will present updated results from phase 1b/2 ELECTRA and ELEVATE clinical studies evaluating elacestrant (ORSERDU®) in combination with other treatments. Both the ELECTRA and ELEVATE studies were designed to overcome different resistance mechanisms observed in estrogen receptor-positive (ER+), HER2-negative (HER2-) metastatic breast cancer (mBC) and improve patient outcomes through novel oral-oral combination treatment options. Data will be presented at the 2024 American Society of Clinical Oncology (ASCO), on June 2 from 9 a.m. to 12 p.m. CT. This press release features multimedia. View the full release here: The ELECTRA study is evaluating elacestrant in combination with abemaciclib in patients with ER+, HER2- metastatic breast cancer with brain metastases; however, the phase 1b portion of this study was conducted in all metastatic sites, including brain metastases. The updated phase 1b results continue to show a satisfactory safety profile, consistent with prior findings, and promising activity in patients with ER+, HER2- advanced or mBC regardless of metastatic site. Based on the results of this portion of the study, the recommended phase 2 dose (RP2D) will be reported as part of the data presentation. Currently, the phase 2 portion of ELECTRA is ongoing at the RP2D to further characterize the efficacy and safety in patients with ER+, HER2- metastatic breast cancer with brain metastases, since both elacestrant and abemaciclib cross the blood-brain barrier. “It is encouraging to see that, even in the early stages of the trial, the combination of elacestrant plus abemaciclib indicates a tolerable and manageable safety pro the patients in the clinical trial,” said Erika Hamilton, MD, Director of Breast Cancer Research and Executive Chair of the Breast Cancer Research Executive Committee for Sarah Cannon Research Institute. “The study continues to demonstrate elacestrant’s potential in combination with other therapies and we look forward to analyzing more data from this combination for this patient population in need of new options.” The ELEVATE study is evaluating elacestrant in combination with CDK4/6 inhibitors (palbociclib, abemaciclib and ribociclib) and with inhibitors of the PI3K/AKT/mTOR pathway (everolimus, alpelisib and capivasertib). The updated Phase 1b results show that the combinations evaluated are consistent with the known safety profiles of each targeted therapy plus standard of care endocrine therapy. Based on the results of this portion of the study, the RP2D will be reported for elacestrant in combination with everolimus. Additional cohorts, including elacestrant plus capivasertib, are currently under evaluation to further characterize the safety, assess efficacy and determine the RP2D for each combination arm. Phase 2 for the combination of elacestrant and abemaciclib in ER+, HER2- metastatic breast cancer, irrespective of the metastatic site, is already ongoing. “As we evaluate the various combinations of elacestrant plus CDK4/6 and PI3K/AKT/mTOR inhibitors, we continue to see consistent and manageable safety findings across all arms of the trial, and so far, elacestrant does not appear to add any incremental toxicity to the combination regimens in which it is being studied,” Hope S. Rugo, MD, Professor of Medicine and Winterhof Family Endowed Professor in Breast Cancer, Director, Breast Oncology and Clinical Trials Education, University of California San Francisco. “These data build on our understanding of elacestrant’s role in metastatic breast cancer and reinforce its potential as an endocrine therapy backbone in combination regimens.” “Since its approval in 2023, ORSERDU has had a meaningful impact as an endocrine therapy for people who are living with ER+, HER2- metastatic breast cancer harboring ESR1 mutations,” said Elcin Barker Ergun, CEO of the Menarini Group. “The data we are presenting at ASCO highlight elacestrant’s potential to further enhance patient outcomes when combined with other compounds.” About The Elacestrant Clinical Development Program Elacestrant is also being investigated in several company-sponsored clinical trials in metastatic breast cancer disease, alone or in combination with other therapies. ELEVATE (NCT05563220) is a phase 1b/2 clinical trial evaluating the safety and efficacy of elacestrant combined with alpelisib, everolimus, capivasertib, palbociclib, ribociclib or abemaciclib. ELECTRA (NCT05386108) is an open-label phase 1b/2, multicenter study evaluating elacestrant in combination with abemaciclib in patients with ER+, HER2- breast cancer. The phase 2 portion evaluates this treatment regimen in patients with brain metastases. ELCIN (NCT05596409) is a phase 2 trial evaluating the efficacy of elacestrant in patients with ER+, HER2- advanced/metastatic breast cancer who received one or two prior hormonal therapies and no prior CDK4/6 inhibitors in the metastatic setting. ADELA (NCT06382948) is a phase 3 randomized, double-blinded trial evaluating elacestrant in combination with everolimus in patients with ER+, HER2- mBC with ESR1-mut tumors. Elacestrant is also being evaluated in additional investigator-led trials, in trials conducted in collaboration with other companies, in metastatic breast cancer as well as in early disease.
