Clinical Trial Summary

This trial aims to evaluate the safety and efficacy of third-line or later irinotecan treatment for locally recurrent or metastatic breast cancer among Chinese patients who have received at least two regimens containing anthracyclines and taxanes.

Description:

Anthracyclines and taxanes are the most effective first-line and second-line treatments for breast cancer, although increased usage in early treatment lines can make it difficult to select a third-line or later treatment. This issue is further complicated by the fact that patients with metastatic breast cancer can become resistant to anthracyclines and taxanes. Thus, there are no consistent international guidelines regarding treatment in this setting.

In China, the treatment procedures for metastatic breast cancer follow the National Comprehensive Cancer Network guidelines, which recommend single-drug treatments for recurrent or metastatic disease, which typically involve anthracyclines, taxanes, vinorelbine, gemcitabine, capecitabine, and eribulin. However, there is no standard international recommendation for patients with metastatic breast cancer who have developed resistance to anthracyclines and taxanes, and there are limited options for third-line or later treatment in this setting.

This trial aims to evaluate the safety and efficacy of third-line or later irinotecan treatment for locally recurrent or metastatic breast cancer among Chinese patients who have received at least two regimens containing anthracyclines and taxanes.

• Eastern Cooperative Oncology Group (ECOG) grade 0-2;

• Life expectancy of = 12 weeks;

• Adequate bone marrow capacity, hepatic functional reserve, and renal functional reserve within 7 days before screening:

Exclusion Criteria:

• Receiving chemotherapy, radiotherapy, HER2/neu-targeted drugs (including trastuzumab), or hormonal therapy within 3 weeks;

• Breast cancer patients who do not receive local treatment and develop brain and dural metastasis. However, patients will be eligible if corticosteroids for brain and dural metastasis have been withdrawn for at least 4 weeks, if the signs and/or symptoms of brain metastasis have been stable for = 4 weeks, and if imaging findings confirm that the disease is stable between the screening and 4 weeks earlier;

• Patients with homozygous mutations in UGT1A1*6 and/or UGT1A1*28 (these patients are susceptible to irinotecan-induced diarrhea);

• Patients with allogeneic organ transplants that require immunosuppressive therapy;

• A history of other malignancies within 5 years, except for cured cervical carcinoma in situ or basal cell skin cancer. Women who are pregnant, lactating, or within their childbearing age but not using adequate contraception;

• Drug abuse and medical, psychological, or social conditions that could interfere with the patient's ability to consent or that might affect the study's results;

• Known or suspected being allergy to the studied drug or any other drug administered in the study;

• Any unstable condition that might jeopardize the patient's safety and compliance.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Objective response rate (ORR)	The ORR will be calculated based on the number of patients who achieve a complete or partial response divided by the total sample size.	1 year
Secondary	Progression-free survival(PFS)	The PFS interval will be calculated from the start of irinotecan treatment to the first instance of tumor progression, treatment failure, or death from any cause. Overall survival will be calculated from the start of irinotecan treatment to death from any cause.	1 year
