The prospective, open-label, single-arm TUXEDO-1 trial enrolled 15 patients with HER2-positive breast cancer and newly diagnosed untreated brain metastases or brain metastases progressing after previous local therapy, previous exposure to trastuzumab and pertuzumab and no indication for immediate local therapy. Patients received trastuzumab deruxtecan intravenously at the standard dose (5.4 mg per kg bodyweight) once every 3 weeks. The primary endpoint was intracranial response rate and results show that two patients (13.3%) had a complete intracranial response, nine (60%) had a partial intracranial response and three (20%) had stable disease as the best intracranial response, with a best overall intracranial response rate of 73.3%. No new safety signals were observed and global quality of life and cognitive functioning were maintained over the treatment duration. \u00abTUXEDO-1 is a prospective study indicating clinically relevant activity of the antibody-drug conjugate trastuzumab deruxtecan in active brain metastases from HER2-positive breast cancer with comparable intra- and extracranial response rates in a pretreated population. In addition, the progression-free survival results indicate prolonged disease control despite the presence of brain metastases. The results therefore suggest that trastuzumab deruxtecan could be safely used for the treatment of patients with active brain metastases from HER2-positive breast cancer, in case immediate local intervention is not indicated, and more generally support the notion that antibody-drug conjugates may be of interest in central nervous system malignancies and, thus, further clinical exploration in this context is warranted\u00bb.[\/vc_column_text][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_single_image image=&#8221;1877&#8243; img_size=&#8221;large&#8221;][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column][vc_custom_heading text=&#8221;The phase 2 TUXEDO-1 trial show that this antibody-drug conjugate has a high intracranial response rate in patients with HER2+ breast cancer and active brain<span class=\"excerpt-hellip\"> [\u2026]<\/span><\/p>\n","protected":false},"author":2,"featured_media":1877,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[39,21],"tags":[],"class_list":["post-2237","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-events","category-uncategorized"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.7 -
