About this study

Official title: A Single-Arm Clinical Study of Nebulized Inhalation of Recombinant Human p53 Adenovirus Injection (Gendicine) for Treatment of Multiple Ground-Glass Lung Nodules

This study aims to evaluate the safety and efficacy of nebulized inhalation of Recombinant Human Ad-p53 Injection (Gendicine®) for the treatment of multiple ground-glass lung nodules. This is a single-arm, open-label clinical study conducted at The First Affiliated Hospital of Guangzhou Medical University in China. We plan to enroll approximately 38 patients who have been diagnosed with multiple ground-glass nodules. All participants in this study will receive the nebulized Gendicine® treatment. After the treatment, we will monitor changes in the nodules through regular chest CT scans and record any potential treatment-related reactions to determine if this novel therapy is safe and effective. This study has been approved by the hospital's Ethics Committee.

Read the detailed description

Background: Ground-glass nodules (GGN) are a common manifestation of early-stage lung adenocarcinoma, and their management strategy (active surveillance or surgical intervention) often presents a dilemma for clinicians and patients. Gendicine® (Recombinant Human Ad-p53 Injection) is a gene therapy product approved in China. Previous studies have shown its ability to induce tumor cell apoptosis and enhance the sensitivity to radiotherapy and chemotherapy in various solid tumors. This study aims to investigate this innovative approach of local administration via nebulized inhalation for treating precancerous lesions or early-stage lung cancer.

Methods: This is a single-arm, open-label, phase II clinical trial utilizing the Simon's optimal two-stage design. The first stage plans to enroll 16 patients. If ≥1 objective response (according to RECIST 1.1 criteria) is observed, the study will proceed to the second stage, with a total planned enrollment of 30 evaluable patients (38 subjects will be recruited accounting for a 20% dropout rate). Participants are patients with multiple ground-glass nodules confirmed by imaging, with at least one nodule pathologically confirmed as malignant. The intervention is nebulized inhalation of Gendicine® at a dose of 1×10¹² VP per time, administered once every three days, for a total of four times. The primary endpoint is the Objective Response Rate (ORR), defined as the proportion of patients achieving Complete Response (CR) or Partial Response (PR) at 6 months post-treatment. Secondary endpoints include safety (assessing adverse events according to CTCAE v5.0), changes in tumor markers, and quality of life scores.

Significance: This study is the world's first clinical trial to explore nebulized inhalation of a gene therapy product for the treatment of lung nodules. Positive results would provide a novel, non-invasive treatment strategy for the very early intervention of lung cancer, potentially delaying or preventing nodule malignancy and avoiding surgical trauma.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groupRoleWhat they receive
Gendicine Nebulization ArmExperimentalParticipants in this single arm of the study will all receive the active intervention, which is Nebulized Inhalation of Recombinant Human p53 Adenovirus Injection (Gendicine®), at a dose of 1×10¹² VP per session. The treatment will be administered once every three days, for a total of four sessions.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Objective Response Rate (ORR)

    The proportion of participants achieving a best overall response of Complete Response (CR) or Partial Response (PR) according to RECIST 1.1 criteria, based on chest CT scan assessments. CR is defined as the disappearance of all target lesions. PR is defined as at least a 30% decrease in the sum of diameters of target lesions.

    Measured: 6 months after the first dose of intervention

Secondary outcomes (1)
  1. Incidence of Treatment-Related Adverse Events

    The number and percentage of participants experiencing any treatment-related adverse event (AE), graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 5.0.

    Measured: From first dose of study intervention until 30 days after the last dose

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Jianxing He, Ph.D (86+020-83062807, drjianxing.he@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Objective Response Rate (ORR) (time frame: 6 months after the first dose of intervention). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07150416, which also lists 10 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Sep 2025.
