NCT05980208

Brief Summary

This is a prospective, multicenter, real-world study aimed at evaluating the efficacy and safety of inetetamab+chemotherapy or inetetamab+pyrotinib+chemotherapy or inetetamab+pertuzumab+chemotherapy in the treatment of HER2 positive inoperable locally advanced or recurrent metastatic breast cancer. The research results will provide new targeted treatment strategies for HER2 positive breast cancer patients.

Outcome Measures

Primary Outcomes (1)

  • Progression-Free Survival

    The survival time from the date of randomization to the date of the first documented progression or date of death, whichever came first, assessed up to 60 months

Secondary Outcomes (3)

  • Objective Response Rate

    From date of randomization until the date at the end of the second treatment cycle (42 days)

  • Overall survival

    The time from randomization to death from any cause, whichever came first, assessed up to 60 months

  • Adverse Events

    The time from randomization to reach the endpoint, assessed up to 60 months

Study Population

First-line treatment of HER2 positive inoperable local advanced or recurrent metastatic breast cancer patients.

You may qualify if:

  • Patients aged ≥18 years and ≤75 years;Patients aged ≥18 years and ≤75 years;
  • Her2-positive invasive breast cancer confirmed by pathological examination met the following conditions:
  • Positive HER2 expression: Immunohistochemical staining (IHC) showed positive HER2 3+ and/or fluorescence in situ hybridization (FISH); Tumor staging: inoperable locally advanced or recurrent metastatic breast cancer; Patients with local recurrence must be confirmed by the investigator to be unable to undergo radical surgical excision.
  • At least one measurable lesion was present according to RECIST1.1 criteria;
  • The ECOG score is 0 to 1;
  • No systematic antitumor therapy (except first-line endocrine therapy) has been received at the locally advanced stage (clinically inoperable) or at the stage of recurrence and metastasis;
  • The functional level of major organs must meet the following requirements (no blood transfusion within 2 weeks prior to screening, no use of leukocyte enhancing and platelet enhancing drugs) :
  • Blood routine: neutrophils (ANC) ≥1.5×109/L; Platelet count (PLT) ≥90×109/L; Hemoglobin (Hb) ≥90 g/L;
  • Blood biochemistry: total bilirubin (TBIL) ≤ upper limit of normal value (ULN), known patients with Gilbert syndrome, TBIL≤2×ULN; Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤1.5×ULN, patients with liver metastasis required ALT and AST≤5×ULN; Alkaline phosphatase ≤2.5×ULN; Urea/urea nitrogen (BUN) and creatinine (Cr) ≤1.5×ULN;
  • Cardiac ultrasound: left ventricular ejection fraction (LVEF) ≥50%;
  • lead electrocardiogram: Fridericia corrected QT interval (QTcF) \<470 msec;
  • Expected survival ≥3 months;
  • Participate in this study voluntarily, sign informed consent, have good compliance and be willing to cooperate with follow-up.

You may not qualify if:

  • Known allergic history of drug components of the program;
  • Patients judged unsuitable for systematic chemotherapy by researchers;
  • Use of endocrine therapy drugs within 14 days before baseline;
  • Patients with only bone or skin as target lesions;
  • Other malignancies, excluding cured cervical carcinoma in situ, skin basal cell carcinoma or squamous cell carcinoma, within the previous 5 years;
  • Peripheral neuropathy ≥ grade 3 according to CTCAE 5.0 criteria;
  • Had received major surgical procedures or significant trauma within 4 weeks prior to randomization, or was expected to receive major surgical treatment;
  • Serious heart disease or discomfort, including but not limited to:
  • heart failure or contraction dysfunction (LVEF \<50%) past medical history high risk or the need for treatment of angina or arrhythmia (such as second degree atrioventricular block type 2 or 3 degree atrioventricular block, ventricular tachycardia) clinical significance of heart valve disease ECG showed wall permeability myocardial infarction poorly controlled hypertension, systolic blood pressure\>150 mmHg and/or diastolic blood pressure\>100 mmHg
  • Dysphagia, chronic diarrhea, intestinal obstruction and other factors affecting drug delivery and absorption;
  • A history of immunodeficiency, including HIV infection, or other acquired, congenital immunodeficiency diseases, or a history of organ transplantation;
  • Participated in other drug clinical studies within 4 weeks prior to screening;
  • There is a third interstitial effusion (such as pleural fluid and ascites) that cannot be controlled by drainage or other methods;
  • Pregnant or lactating women, women of childbearing age who are unable to take effective contraceptive measures throughout the trial period;
  • Have a serious concomitant disease or other co-medical condition that interferes with planned treatment or any other condition that is not suitable for participation in the study, such as active hepatitis B, lung infection requiring treatment, etc.
