Sacituzumab Govitecan Combined With Head Radiotherapy for Her2-negative Breast Cancer Brain Metastases
43 participantsStarted 2024-06-15
Plain-language summary
The incidence of brain metastasis of Her2-negative breast cancer is high, which seriously affects the prognosis of patients.The treatment of brain metastasis of Her2-negative breast cancer is still tricky. The local efficacy of head radiotherapy for breast cancer brain metastases is remarkable, and systemic tumor progression in patients with brain metastases is the main reason for treatment failure. Sacituzumab Govitecan is the only Trop-2 antibody-coupled drug (ADC) approved for the treatment of unresectable locally advanced or metastatic Her2-negative breast cancer. However, the objective remission rate of Sacituzumab Govitecan for intracranial metastatic lesions has not been satisfactory. This study is an open, uncontrolled phase II clinical study to observe the efficacy and safety of Sacituzumab Govitecan combined with intracranial radiotherapy in the treatment of patients with brain metastases from Her2-negative breast cancer, in order to find a more effective treatment method.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
1-year CNS progression-free survival (NPFS)
Timeframe: From the time patients receive this treatment until the next 1 year
. Presence of serious and/or uncontrolled comorbidities that may affect participation: 1) allergy to study medications or adjuvant materials; 2) history of immunodeficiency, including HIV-positive or other acquired or congenital immunodeficiency diseases; 3) serious concomitant illnesses;
. Pregnant and lactating female patients; female patients of childbearing age who are unwilling to use effective contraception during the trial period;
. Patients who are unable to complete enhanced contrast MRI;
. Patients who have been treated with Sacituzumab Govitecan and are resistant to the drug;
. Any other condition that, in the opinion of the investigator, makes the patient ineligible for study participation.
