Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The main goal of this clinical trial is to evaluate the efficacy of Disitamb Vedotin combined with pyrotinib in previously untreated histologically proven HER2 positive early breast cancer and evaluate the PCR DFS,OS and safety of the subjects.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

1.18 to 75 years old (at the time of signing the informed consent form), regardless of gender.

2. Subject type and disease characteristics. Histologically confirmed HER2 positive EBC subjects:

  1. evaluated as HER2 positive in local laboratories according to ASCOCAP guidelines.
  2. Single and multifocal tumors (greater than 1 tumor area limited to the same quadrant as the primary tumor) must be sampled from 1 lesion and laboratory confirmed as HER2 positive.
  3. Multicenter tumors (multiple tumors involving more than one breast quadrant) must sample one lesion from each affected quadrant and be confirmed as HER2 positive by the central laboratory.
  4. According to ASCOCAP guidelines, tumors are either HR positive or HR negative (ER and PgR negative).

  5. Clinical staging at visit (based on breast X-ray or breast MRI evaluation): Stage II-IIIC determined by the AJCC staging system, 8th edition. (f) Lymph node involvement is determined by fine needle aspiration or coarse needle aspiration biopsy (if applicable).

    3. When randomized, ECOG physical fitness status is 0 or 1 point.

    Exclusion Criteria:

    1. Previous history of invasive breast cancer.
    2. Stage IV breast cancer according to AJCC staging system version 8.
    3. Within 3 years, there is any primary malignant tumor, except for fully resected non-melanoma skin cancer or cured in situ disease.
    4. DCIS medical history, except for the subjects who only received Mastectomy
    5. According to the judgment of the researchers, there is evidence of any diseases (such as severe or uncontrolled systemic diseases, including persistent or active infections, uncontrolled hypertension, kidney transplantation and active bleeding diseases, and severe chronic gastrointestinal diseases related to diarrhea) that the researchers consider to be unfavorable for the participants to participate in the study or may affect adherence to the protocol.
    6. Uncontrolled infection requiring intravenous administration of antibiotics, Antiviral drug or antifungal drugs.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
pathologic complete response（pCR）
Time Frame: 1 year
The pCR rate is defined as the proportion of subjects who, after completion of neoadjuvant therapy, showed no evidence of residual invasive lesions in H&E staining in completely excised breast specimens and all sampled local lymph nodes (ypT0/TisypN0) through central evaluation
1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Disease free survival （DFS)
Time Frame: 3 years
The time from randomization until disease recurrence or death due to progression of the disease.
3 years
Overall Survival（OS）
Time Frame: 5year
It is defined as the time from the start of treatment to death for any reason.
5year
The Number of Participants Who Experienced Adverse Events (AE)
Time Frame: 1 year
