What is being measured

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

  1. Progression free survival (PFS)

    Baseline to measured date of progression or death from any cause

    Measured: evaluated in 24 months since the treatment began

Secondary outcomes (4)
  1. 1. Objective response rate (ORR)

    Baseline to measured stable disease

    Measured: tumor assessment every 6 weeks since the treatment began,up to 24 monthss

  2. 2. Duration of Overall Response(DoR)

    The duration of overall response is measured from the time that measurement criteria are met for complete response or partial response until the first date that recurrent or progressive disease is objectively documented.

    Measured: tumor assessment every 6 weeks since the treatment began,up to 24 months

  3. 3. Overall survival (OS)

    Baseline to measured date of death from any cause

    Measured: the first day of treatment to death or last survival confirm date,up to 24 months

  4. 4. Adverse events

    Toxicity according to the Common Terminology Criteria for Adverse Events (CTCAE) Version 4.03. The number of Participants with adverse events will be recorded at each treatment visit.

    Measured: up to 24 months

Questions about this trial

What is this clinical trial studying?

A study testing Adebrelimab+TP/FP+ radiation therapy and Adebrelimab+FP/TP+ radiation therapy in people with Esophageal Squamous Cell Carcinoma, run by Hebei Medical University Fourth Hospital.

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 9 inclusion and 12 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The record says: withdrawn, as of the sponsor's last update on 26 Aug 2025. Status can change between updates, so confirm with the study contact before making plans.

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?

The study was withdrawn before enrolling participants, so there are no results.

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 (PFS) (time frame: evaluated in 24 months since the treatment began). 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 26 Aug 2025.
