A Phase 2 interventional study of SBRT and Cadonilimab in Recurrent or Metastatic Esophageal Squamous Cell Carcinoma, sponsored by The First People's Hospital of Changzhou. Not yet recruiting. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2023-02-17.

The entire treatment process is divided into two phases: Phase I SBRT combined with PD-1/CTLA-4 bispecific antibody (AK104) and Phase II AK104 single-agent maintenance therapy.
Phase I SBRT combined with AK104 treatment Target area and dose of SBRT: Select a relapsed or metastatic lymph node or lesion that has little effect on surrounding normal tissues and has not been irradiated before, and then perform radiation therapy with a total dose of 24-50Gy/8-12.5Gy/3-4f per lesion (the specific target area and dose range will be decided by the treating physician). AK104 is administered within one week after SBRT, and the regimen for AK104 is 10 mg/kg as a single dose. If multiple target lesions are treated with SBRT, multiple cycles of 21 days each are possible. When patients are treated with multiple courses of radiotherapy, it is difficult to ensure the accuracy of the overlapping doses of the re-course of radiotherapy, and the cumulative dose of organs at risk (OAR) is evaluated using the deformable image registration (DIR) technique.
Phase II AK104 monotherapy maintenance phase Monotherapy maintenance with AK104 10 mg/kg every 21 days until progression, up to one year if no progression. Patients were enrolled in Phase I and Phase II for a minimum of three cycles.
In addition, 10 mL of peripheral blood was drawn from patients before each cycle of treatment and analyzed by flow cytometry for lymphocyte subpopulation. And the changes of HMGB1 and cytokines IL-8, IL-6, IL-12, IFN-α, IFN-β, IL-2, IL-4, IL-5, INF-γ, TNF-α, IL-10, TGF-β were detected by ELISA test. By testing the above indicators, they are used to respond to the immune status after treatment as well as to screen for valid indicators that can be used to assess efficacy.
Throughout the study period, the assessment should be performed as much as possible according to the imaging assessment plan time points specified in the protocol. Tumor imaging assessments will be performed every 6 weeks during the first phase of treatment and every 9 weeks during the second phase of treatment. This project used velosity software to perform clinical tumor imaging assessment according to RECIST 1.1 criteria and irRECIST and iRECIST criteria assessment every 6 weeks; NCI-CTCAE 5.0 was used for safety assessment and adverse events were recorded throughout the study until 30 days after the end of treatment.
After the end of treatment, all subjects will be followed for survival every 3 months until death, loss to follow-up, withdrawal of knowledge, or the sponsor's decision to terminate the study.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
age ≥ 18 years. 2. patients enrolled must be eligible for treatment-naïve patients with recurrent or advanced esophageal squamous carcinoma with definite measurable recurrent or metastatic lesions.
Exclusion Criteria:
pregnant gestational or lactating women. 2. those with a history of other malignant diseases in the last 5 years. 3. persons with a history of uncontrolled epilepsy, central nervous system disease, or psychiatric disorder whose clinical severity, as judged by the investigator, may prevent signing an form or affect patient compliance with medication.
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
PD-1, PD-L1 and CTLA-4 are proteins that act as brakes on the immune system. Checkpoint inhibitors, such as pembrolizumab or nivolumab, block them so the immune system can attack a cancer.
PD-L1 can also be measured in a tumour sample. Some scores count stained tumour cells only (TPS); others also count certain immune cells (CPS). The study names the score and the minimum it uses.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.
The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.
The standard rules for measuring tumours on CT or MRI scans, to tell whether a cancer is shrinking, stable or growing during treatment.
“Measurable disease per RECIST 1.1” usually means at least one tumour 10 mm or more at its longest on a CT scan, or a lymph node 15 mm or more across its short axis.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
