July 5, 2026 updated by: Zhimin Shao, Fudan University

Artificial Intelligence Model-Guided Neoadjuvant Anti-HER2 Targeted Therapy: A Randomized, Controlled, Open-Label, Multicenter Phase III Clinical Study

Based on total pathologic complete response (tpCR) after surgery, to evaluate the efficacy of an artificial intelligence model-matched anti-HER2 targeted treatment strategy (investigational arm) versus nab-paclitaxel + carboplatin + trastuzumab + pertuzumab (PCbHP, control arm) as neoadjuvant therapy for patients with early or locally advanced human epidermal growth factor receptor 2 (HER2)-positive breast cancer.

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

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: through study completion, up to 24 weeks
pCR is defined as the absence of noninvasive tumor residuals in breast and axillary lymph nodes (ypT0/is ypN0) after neoadjuvant therapy.
through study completion, up to 24 weeks

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
Objective Response Rate (ORR)
Time Frame: up to 24 weeks
ORR is defined as the proportion of patients who achieved a complete response (CR) or partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1
up to 24 weeks

The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
