GzmB-PET/CT to Evaluate Neoadjuvant Therapy Efficacy in Breast Cancer (GzmB-PET4BC)

December 5, 2024 updated by: Kunwei Shen, Shanghai Jiao Tong University School of Medicine

Clinical Study on the Evaluation of Neoadjuvant Therapy Efficacy in Breast Cancer Using PET/CT With Granzyme B Imaging Probe

To explore the efficacy of 68Ga-GZMB PET/CT in assessing the response to neoadjuvant therapy for breast cancer, and to investigate the optimal SUVmax threshold of 68Ga-GZMB PET/CT for predicting pathological complete response (pCR), aiming to provide a new and effective means for accurately and non-invasively evaluating the efficacy of neoadjuvant therapy.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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

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

Time Frame: through study completion, an average of 1 year
Optimal SUVmax threshold of 68Ga-GZMB PET/CT for predicting pathological complete response after neoadjuvant therapy in breast cancer
through study completion, an average of 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.
