Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Cyclin-dependent kinases 4 and 6 (CDK4/6) inhibitors combined with hormonal therapy are the current standard frontline treatment for patients with hormone receptor-positive (HR+), human epidermal growth factor receptor 2 (HER-2)-negative metastatic breast cancer (MBC). However, the optimal treatment after progression on CDK4/6 inhibitors remains unknown. Anlotinib is an oral multi-target tyrosine kinase inhibitor (TKI) that strongly inhibits VEGFR, PDGFR, FGFR, and c-kit. This study aimed to evaluate the safety and efficacy of anlotinib-based combination therapy in patients with HR+ MBC previously treated with a CDK4/6 inhibitor.

Anlotinib+eribulin/nab-paclitaxel/etoposide/capecitabine/pembrolizumab/ sintilimab/ fulvestrant, etc

Anlotinib (8/10/12 mg daily, Day 1-14 of each cycle) was administered orally to fasting patients, with dose reductions to 10 mg or 8 mg in cases of intolerable toxicity. Combination agents included eribulin, nab-paclitaxel, etoposide, capecitabine, pembrolizumab, sintilimab, or fulvestrant, among others.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Female patients aged 18 to 75 years, with an ECOG score of 0-1, and an expected survival of at least 3 months;
* Presence of measurable lesions as defined by RECIST 1.1 criteria;
* Histopathologically confirmed HR-positive/HER2-negative breast cancer. HER2 negativity is determined by an immunohistochemistry (IHC) result of HER2 (0/1+). If the result is HER2 (++), a FISH or CISH test is required to confirm the absence of HER2 amplification;
* Patients who have undergone multiple lines of advanced therapy with no remaining standard treatment options;
* Prior treatment with at least one line of CDK4/6 inhibitors and endocrine therapy;
* Disease progression following aromatase inhibitor (AI) or fulvestrant combined with CDK4/6 inhibitors, either as adjuvant therapy or as systemic treatment for advanced disease.

Exclusion Criteria

* Patients with HER2-positive breast cancer confirmed by histology or cytology;
* Patients who discontinued therapy due to non-disease progression reasons, such as adverse events or other non-medical factors;
* Detection of a second primary malignant tumor at the time of enrollment;
* Failure to complete CDK4/6 inhibitor therapy;
* Pregnant or breastfeeding patients;
* Presence of third-space fluid accumulation (e.g., pleural effusion, ascites, pericardial effusion) that cannot be managed through drainage or other methods;
* Patients previously treated with anti-angiogenic agents, including small molecules such as anlotinib or apatinib, and large molecules such as bevacizumab;
* Patients currently receiving any other anti-tumor treatment for any other malignancies.
