About this study

Official title: Consolidative Thoracic Radiotherapy for Extensive-stage Small-cell Lung Cancer Treated With Chemo-immunotherapy Followed by PD-1/PD-L1 Maintenance Therapy:an Open Label, Single Arm Prospective Trial

This is an open-label, single arm Phase II study designed to evaluate the efficacy and safety of thoracic radiotherapy for extensive-stage small-cell lung cancer treated with PD-1/PD-L1 plus etoposide platinum followed by PD-1/PD-L1 maintenance therapy

Read the detailed description

This study a single arm prospective phase II study. All the enrolled patients will be patients with ES-SCLC who did not have PD (determined as per the RECIST v1.1) after 6 cycle of platinum-based chemotherapy in combination with an anti-PD-1/L1. Then, those enrolled patients would be treated with thoracic radiotherapy concurrently with PD-1/PD-L1 maintenance therapy, and the total maintenance therapy time should at least more than 6 months.

What participants receive

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

  • thoracic radiotherapyRadiation

    Four courses of carboplatin/etoposide/anti-PD-1/PD-L1 every 3 weeks All the enrolled patients will be patients with ES-SCLC who did not have PD (determined as per the RECIST v1.1) after 6 cycle of platinum-based chemotherapy in combination with an anti-PD-1/L1. Then, thoracic radiotherapy of 45 Gy/15 fractions. PD-1/PD-L1 maintenance therapy concurrently and after thoracic radiotherapy at least more than 6 months, or until intolerable toxicity, progressive disease leading to a need for other treatment, or until the patient no longer wishes to continue treatment.

What is being measured

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

  1. 1-year progression-free survival

    PFS is defined as the period from the start of receiving the first EC/EP chemotherapy plus PD-1/PD-L1 inhibitor to disease progression.

    Measured: 12 months after last patient entry

Secondary outcomes (3)
  1. 1-year overall survival

    Measured: 12 months after last patient entry

  2. toxicities

    Number of participants with treatment-related adverse events and the grade of adverse events as assessed by CTCAE v4.0

    Measured: 12 months after last patient entry

  3. 5-year overall survival

    Measured: 5-year after last patient entry

Questions about this trial

What is this clinical trial studying?

A study testing thoracic radiotherapy in people with Small-cell Lung Cancer, run by Ruijin 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 10 inclusion and 8 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: looking for participants now, as of the sponsor's last update on 12 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.

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?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

1-year progression-free survival (time frame: 12 months after last patient entry). 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 12 Aug 2026.
