A panel of experts consisting of Joyce O’Shaughnessy, MD; Priyanka Sharma, MD; Claudine Isaacs, MD; Heather McArthur, MD; and Hope S. Rugo, MD, FASCO recently participated in a Peer Exchange to discuss the latest advancements in the treatment of brain metastases in HER2-positive breast cancer.
During the discussion, O’Shaughnessy and McArthur shared insights on recent developments in this area. McArthur specifically highlighted findings from the HER2CLIMB trial, showing a notable survival benefit of the tucatinib-containing regimen, especially in patients with brain metastases. She emphasized the groundbreaking impact of this data on treatment strategies.
Furthermore, the experts discussed the results of the TUXEDO phase 2 trial, which explored the efficacy of trastuzumab deruxtecan (T-DXd) in patients with active brain metastases. The trial revealed an impressive progression-free survival of nearly 2 years in a high-risk population. Additionally, the I-ROSETTE study conducted by a Japanese group evaluated T-DXd in patients with leptomeningeal disease, demonstrating encouraging overall survival rates.
Overall, the panel highlighted the evolving landscape of HER2-positive breast cancer treatment, with new strategies addressing the needs of patients with brain and leptomeningeal involvement. The discussion shed light on the promising developments in this field.
