Study summary

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.

Study population

HR+ metastatic breast cancer previously treated with CDK4/6is

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Female patients aged 18 to 75 years, with an score of 0-1, and an expected survival of at least 3 months;
  • Presence of as defined by 1.1 criteria;
  • Histopathologically confirmed HR-positive/-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 therapy or as systemic treatment for advanced disease.

Exclusion criteria

Exclusion Criteria:

  • Patients with -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 .
Terms in these criteria, in plain language(6)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Measurable disease

The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.

The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.

RECIST

The standard rules for measuring tumours on CT or MRI scans, to tell whether a cancer is shrinking, stable or growing during treatment.

“Measurable disease per RECIST 1.1” usually means at least one tumour 10 mm or more at its longest on a CT scan, or a lymph node 15 mm or more across its short axis.

HER2

HER2 is a protein, made from the ERBB2 gene, that drives the growth of some cancers. A study may look for a level of the protein, extra copies of the gene, or a particular change in it.

In breast cancer, protein tests are read as HER2-positive, HER2-low or HER2-negative; other cancers use their own rules. Check which test result the study requires.

Adjuvant and neoadjuvant

Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumour. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Interventions

  • OtherAnlotinib+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.

This study also gives Pembrolizumab, Fulvestrant. No intervention listed here names it: that was found by reading the record.

What researchers measure

Primary outcomes

  1. Progression free survival (PFS)

    Progression-free survival estimated using Kaplan-Meier methods is defined as the time from the date of informed consent to the earlier of death or disease progression. Patients alive without disease progression are censored at the date of last disease evaluation. Progressive disease (PD) based on RECIST 1.1 is at least a 20% increase in the sum of longest diameter (LD) of target lesions taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. Equivocal progression of non-target lesions also qualifies as PD.

    Time frame: through study completion, an average of 1 year

Secondary outcomes

  1. Objective response rate (ORR)

    The ORR will be defined as the proportion of patients in the Efficacy Evaluable patient Set who achieve complete response (CR) and partial response (PR)

    Time frame: through study completion, an average of 1 year

  2. Disease control rate (DCR)

    The DCR will be defined as the proportion of patients in the Efficacy Evaluable patient Set who achieve complete response (CR) or partial response (PR) or stable disease (SD).

    Time frame: through study completion, an average of 1 year

  3. Overall survival(OS)

    OS, defined as the time from the date of informed consent until to the date of death, regardless of the cause of death.

    Time frame: through study completion, an average of 5 year

  4. Incidence of Treatment-Emergent Adverse Events (Safety)

    All the treatment-related adverse events occurred as assessed by CTCAE v4.0

    Time frame: through study completion, an average of 1 year

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 16, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
