A Prospective, Multicenter, Observational Cohort Study to Evaluate the Efficacy and Safety of a Novel Anti-tumor Drug As a Radiosensitizer in Patients with Advanced Breast Cancer Brain Metastasis.

Study Purpose

A prospective, multicenter, observational cohort study to evaluate the efficacy and safety of a novel anti-tumor drug as a radiosensitizer in patients with advanced breast cancer brain metastasis.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Observational [Patient Registry]
Eligible Ages	18 Years and Over
Gender	All

More Inclusion & Exclusion Criteria

Inclusion Criteria:

1. Males or females who are at least 18 years of age on the day of signing the informed consent form. 2. Patients with advanced breast cancer that is inoperable and has metastasized to the brain, confirmed by histology or cytology. 3. Patients who are planned to receive, currently receiving, or have completed intracranial radiotherapy after discussion by a multidisciplinary team (MDT) at the stage of brain metastasis. 4. Patients who are planned or currently receiving a systemic treatment regimen with a novel anti-tumor drug selected by the physician, within 3 weeks before radiotherapy, during radiotherapy, or within 3 weeks after completion of radiotherapy. These drugs include: ADC drugs (such as T-DXd, T-DM1, etc.), CDK4/6 inhibitors, TKI drugs (such as Pyrotinib, Tucatinib, etc.), Novel chemotherapy drugs (such as Utidelone, Irinotecan liposomes, etc.), Bevacizumab, PD-1/PD-L1 inhibitors, etc. 5. Patients with a traceable medical history during the treatment period. 6. Patients who are able to sign the informed consent form to participate in the study.

Exclusion Criteria:

1. The subject has leptomeningeal metastasis. 2. If the patient has concurrent brain metastasis, the neurological symptoms are too severe to cooperate with radiotherapy. 3. The subject has not signed the informed consent form. 4. Pregnant or breastfeeding women. 5. Other situations deemed by the investigator as unsuitable for inclusion in the study.

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT06839547
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
