About this study

Official title: A Multicenter Prospective Real-world Study on Bisphosphonates Targeting Triple-negative Breast Cancer

Triple-negative breast cancer has a poor prognosis and lacks effective adjuvant treatment. A number of preclinical and clinical trials have shown that bisphosphonates have direct or indirect anti-tumor activity, and early use of bisphosphonate adjuvant therapy can prevent cancer recurrence and metastasis including bone metastasis and greatly improve the prognosis of cancer patients. Bisphosphonates have the advantages of low cost, low toxicity, and strong tolerance and can be used as an auxiliary treatment for triple-negative breast cancer. The preliminary study found that bisphosphonates can be chimeric with erlotinib, an epidermal growth factor receptor tyrosine kinase inhibitor, which can synergistically inhibit the in vitro tumor formation of cancer (such as non-small-cell lung cancer and breast cancer) cells and the growth of transplanted tumors. Therefore, the purpose of this multi-center prospective real-world study was to further investigate the effects of bisphosphonate adjuvant therapy on breast cancer.

Read the detailed description

Triple-negative breast cancer lacks expression of estrogen receptor, progesterone receptor, and proto-oncogene HER2 as shown by immunohistochemical examination. Its incidence accounts for 15-25% of that of all breast cancer types. This type of breast cancer lacks the opportunity of endocrine therapy and anti-human epidermal growth factor receptor 2 (HER2) therapy. The main currently available treatment is still chemotherapy. Some patients may choose anti-angiogenic therapy. The prognosis of triple-negative breast cancer is worse than that of other types of breast cancer due to fewer treatment options. Bisphosphonates used to treat bone metastasis of breast cancer have been shown to have anti-tumor effects and can be used as an adjuvant treatment for triple-negative breast cancer. The preliminary study found that bisphosphonates can be chimeric with erlotinib, an epidermal growth factor receptor tyrosine kinase inhibitor, which can synergistically inhibit the in vitro tumor formation of cancer (such as non-small-cell lung cancer and breast cancer) cells and the growth of transplanted tumors. The persistence of tumor stem cells is reportedly the root cause of malignant biological behavior of triple-negative breast cancer. Bisphosphonates may synergistically inhibit triple-negative breast cancer (stem) cells with existing molecular targeted drugs.

Although randomized controlled trials can provide highest-level clinical evidence, the test conditions should be strictly controlled, resulting in a small sample size and short follow-up time. However, real-world studies can include patients with multiple diseases and treatment strategies can be adjusted according to patient's needs and clinical conditions. In addition, a variety of interventions can be simultaneously used to accurately meet patient's needs, so that the research evidence is more clinically useful. Therefore, the purpose of this multi-center prospective real-world study was to investigate the significance of use of bisphosphonates as an adjuvant therapy against breast cancer.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Zoledronic AcidDrug

    Based on routine treatment, 4 mg zoledronic acid (Novartis Pharma Stein AG, Switzerland, registration No. H20140218) was intravenously administered, once every 3-4 weeks, for 1-2 years.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Pathologic complete response time

    Pathologic complete response is defined as no residual invasive tumor cells in the breast and axillary lymph nodes

    Measured: 5 years

Secondary outcomes (5)
  1. Disease-free survival

    It refers to the time from the start of the enrollment to the recurrence of the disease or the death of the patient due to disease progression.

    Measured: 5 years

  2. Overall survival

    The length of time from either the date of diagnosis or the start of treatment for cancer, that patients diagnosed with the disease are still alive.

    Measured: 5 years

  3. Incidence of osteoporosis

    Osteoporosis is considered to be present when a patient's bone density or bone mineral content is more than 2.5 standard deviations below the mean value of normal adult bone density.

    Measured: 5 years

  4. Incidence of bone-related events

    Incidence of bone pain, fracture and other bone related events.

    Measured: 5 years

  5. Incidence of other distant organ metastasis-related events

    Incidence of metastasis to other distant organs such as the lung, liver, bone marrow, brain and ovary.

    Measured: 5 years

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Cancer, run by Shengjing Hospital at 3 sites in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 20 Jul 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Xi Gu (86-18940255116, jadegx@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pathologic complete response time (time frame: 5 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Jul 2021.
