About this study

Official title: Hybrid Dose-fraction Radiotherapy for Metastatic Driven-genes Negative Non-small Cell Lung Cancer: A Phase II Multi-institutional Study

The combination of immune checkpoint inhibitors (ICI) and local ablative radiotherapy has been demonstrated to be able to increase the survival of patients with metastatic driven-genes negative non-small cell lung cancer. Various dose-fraction of radiotherapy could exert different effects on the immune system. Ablative-dose could induce immunogenic cell death through the activation of CD8+(Cluster of Differentiation) T cells. Low-dose could modulate immune microenvironment from immunosuppression to inflammatory anti-tumor phenotype. This trial is designed to validation the safety and primary efficacy of the combination of hybrid dose-fraction radiotherapy with ICI for metastatic driven-genes negative non-small cell lung cancer patients.

Read the detailed description

Trial Title: Hybrid dose-fraction Radiotherapy for metastatic driven-genes negative non-small cell lung cancer: A phase II multi-institutional study Trial Objective: To explore the safety and primary efficacy of the combination of hybrid dose-fraction radiotherapy with ICI for metastatic driven-genes negative non-small cell lung cancer patients.

Trial Design: This trial is designed to enroll 74 patients with metastatic driven-genes negative non-small cell lung cancer to receive the combination of hybrid dose-fraction radiotherapy with ICI.

Staging Examination before Radiotherapy: a. ECOG scoring. b. Cranial contrast MRI and PET-CT (Positron Emissions Tomography), or cranial contrast MRI (preferred), chest contrast CT, abdominal ultrasonography and bone scan. c. Bronchoscopy for centrally located lung cancer.

Inductive therapy ICI±chemotherapy for 4-6 cycles. Pembrolizumab and Tislelizumab are preferred. Chemotherapy regimens could be referred to NCCN (National Comprehensive Cancer Network) guidelines.

Restaging examination after inductive therapy is mandatory: a. ECOG scoring. b. Cranial contrast MRI, chest contrast CT, abdominal ultrasonography.

Patients with disease PR or SD (RECIST v1.1) evaluated by restaging after inductive therapy could be included into this trial. Patients would receive hybrid dose-fraction radiotherapy and ICI maintenance.

Radiotherapy CT Simulation: CT with intravenous contrast is recommended for simulation. Scan thickness should be less than 5 mm from lower margin of mandibular to lower margin of L2. For pulmonary lesions, 4D-CT (Four-Dimensional CT) localization is recommended.

Delineation of Targets:

For patients with oligometastasis, including synchronous oligometastatic disease \& metachronous oligorecurrence, all lesions should be prescribed with an ablative dose. The dose-fraction modalities are as following:

Thoracic lesions: 50Gy/5f (50 Gray/5 fractions), 60Gy/8f, 60Gy/15f, 48Gy/12f. Intracranial lesions: 30Gy/10f (Whole Brain Irradiation), 30Gy/3f, 30Gy/5f, 45Gy/15f.

Hepatic lesions: 50Gy/5f, 40Gy/5f, 32Gy/4f. Adrenal lesions: 50Gy/5f, 40Gy/5f, 32Gy/4f. Osseous lesions: 27Gy/3f, 40Gy/5f, 30Gy/5f, 39Gy/13f. Other lesions: Refer to the above dose-fraction. For patients with systemic metastasis, high-dose should be prescribed to 1-3 lesions (longest diameter>1cm). All of the remaining lesions should be given low-dose. High-dose includes 24-40Gy/3-5f. Low-dose includes 6-15Gy/4-10f.

The Planning Target Volume (PTV) was defined as an 8-mm margin of the GTV (Gross Tumor Volumn) for tumor motion and set-up variations.

The delivery of ablative dose and high-dose should utilize the technology of SABR (Stereotactic Ablative Body Radiotherapy).

Dosimetric Limitation of Organ at Risk: 95% prescription dose should cover 100% PTV and 95% PTV should receive 100% prescription dose.

The dose constraints of organs at risk could refer to TG 101 (Task Group 101) report.

Treatment Implementation: Radiotherapy is implemented every day. Cone-beam CT should be utilized every day to minimize set-up error.

Follow-up: Patients should be follow-up every three months right after the completion of radiotherapy to disease progression.

Primary Endpoint: Progress-free Survival (PFS).

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Hybrid dose-fraction Radiotherapy combined with immune checkpoint inhibitors in people with Non-Small Cell Lung Cancer, run by Anhui Provincial Hospital at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 14 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Progression-free Survival (time frame: 1-year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 14 Aug 2026.
