研究概览
简要总结
TUXEDO-4 is an international, multicentric, single arm, phase II study aiming to gather additional solid evidence of Trastuzumab-Deruxtecan (T-DXd) activity in patients with Human Epidermal Growth Factor Receptor 2 (HER2)-low breast cancer with active brain metastases.
This study will analyze the efficacy of T-DXd as determined by overall response rate (ORR) at any timepoint as judged by best CNS response according to RANO-BM criteria.
详细描述
This is an international, multicentric, single arm, phase II study to evaluate the safety and efficacy of T-DXd in HER2-low breast cancer with newly diagnosed or progressing brain metastases with or without untreated type II leptomeningeal disease (LMD).
Upon meeting all selection criteria, a total of 27 patients will be enrolled as follows: 13 patients will be accrued in stage 1 to receive T-DXd and additional 14 patients will be accrued in stage 2 according to the number of responses seen in stage 1.
The main objective is to analyze the efficacy of T-DXd as determined by ORR at any timepoint as judged by best CNS response according to RANO-BM criteria.
End of study (EoS) will occur 11 months after the last patient included in the Study initiates T-DXd treatment, unless premature termination of the Study. EoS is defined as the last data point at the last participant's visit and will occur after the Study treatment termination of the last patient in the Study.

Corticosteroids (dexamethasone at 4 mg or equivalent doses) are allowed only for the treatment of bone metastases or perifocal brain metastases oedema and for the treatment of specific adverse drug reactions. The use of ≥ 4 weeks of stable corticosteroid therapy (4 mg/day) in patients with BM can be discussed with the Medical Monitor. Note: Hematopoietic growth factors may be used for prophylaxis or treatment based on the clinical judgment of the investigator. Concomitant use of dietary supplements, medications not prescribed by the Investigator, and alternative/complementary treatments is discouraged, but not prohibited. Prophylactic or supportive treatment of Study-drug induced adverse events will be otherwise as per investigator's discretion and institutional guidelines.
