(“ALX Oncology” or “the Company”) (Nasdaq: ALXO), a clinical-stage biotechnology company advancing therapies that boost the immune system to treat cancer and extend patients’ lives, announced results from a Phase 1b/2 clinical trial demonstrating the company’s investigational CD47-blocker evorpacept in combination with Jazz Pharmaceuticals’ zanidatamab generates promising anti-tumor activity in patients with both HER2-positive and HER2-low advanced breast cancer. The findings, which are the first from a clinical trial evaluating the safety and efficacy of evorpacept and zanidatamab in heavily pretreated patients with metastatic breast cancer (mBC), will be presented on Thursday, December 12 in a poster spotlight presentation (#PS8-09) at the 2024 San Antonio Breast Cancer Symposium (SABCS). “These data suggest that HER2-positive patients whose cancer has been heavily pretreated may benefit from CD47 inhibition via evorpacept’s unique mechanism when combined with a HER2-targeted agent,” said Alberto J. Montero, M.D., MBA, Clinical Director, Breast Cancer Medical Oncology Program, Case Western Reserve University, and the study’s principal investigator. “New therapeutic options with better safety profiles are desperately needed for these patients, and this is particularly true once disease progresses following advanced, standard-of-care therapies such as ENHERTU.” The Phase 1b/2 open-label, multi-center clinical trial (NCT05027139) evaluated the potential of evorpacept, a highly differentiated, investigational CD47 blocker, in combination with zanidatamab, a dual HER2-targeted bispecific antibody, as a novel treatment for patients with previously treated inoper...
