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.

Detailed Description

It is challenging to noninvasively early evaluate the immunotherapy response of cancer. The study will evaluate the application value of 68Ga-grazytracer PET/CT in the early evaluation of neoadjuvant immunotherapy response in resectable non-small cell lung cancer (NSCLC). Potential participants will be assessed for inclusion, including the verification of clinical stage and eligibility. Eligible patients with clinically stage IB-IIIA NSCLC will be received standardized neoadjuvant immunotherapy (every 3 weeks for 3 cycles). Patients with nonsquamous NSCLC will be received pembrolizumab plus platinum-pemetrexed, and lung squamous cell carcinoma patients will be received pembrolizumab plus platinum-paclitaxel. 68Ga-grazytracer PET/CT imaging will be performed at baseline and before cycle 3. Pathological response of the primary (MPR vs. Non-MPR), imaging response (iPR vs. Non-iPR; MR vs. MD), and 68Ga-grazytracer PET/CT imaging (Positive vs. Negative) will be given special attention.

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

Description

Inclusion Criteria:

  1. Pre-treatment stage as clinical IB-IIIA (AJCC/UICC 8th Edition);
  2. Curative resectability has to be explicitly verified by the experienced surgical investigator;
  3. Histologically confirmed diagnosis of primary non-small lung cancer.
  4. Men and women aged 18 Years to 75 Years;
  5. Eastern Cooperative Oncology Group (ECOG) performance status: 0-1;
  6. expected survival ≥ 6 months;
  7. Sign on the informed consent form (ICF).

Exclusion Criteria:

  1. Histologically confirmed were NOT NSCLC;
  2. Lung cancer that can not be resected or has distant metastasis, or for other reasons can not tolerate surgery;
  3. Patients with previous malignancies (except non-melanoma skin cancers, and the following in situ cancers: bladder, gastric, colorectal, endometrial, cervical, melanoma, or breast) are excluded unless a complete remission was achieved at least 2 years prior to study entry AND no additional therapy is required during the study period;
  4. Any active or history of autoimmune disease, or history of syndrome that required systemic steroids or immunosuppressive medications. The subjects were innate or acquired immunodeficiency (such as HIV), or active hepatitis (hepatitis B reference: HBsAg) positive; Hepatitis C reference: HCV antibody positive;

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
Major Pathological Response (MPR)
Time Frame: MPR will be assessed within 3 weeks after surgery
Defined as the incidence rate in postoperative pathology where the percentage of surviving tumor cells in the tumor bed is ≤ 10%, regardless of the presence or absence of live tumor cells in the lymph nodes.
MPR will be assessed within 3 weeks after surgery

Study Major Dates

Study Start (Estimated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
December 30, 2024

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
