About this study

Official title: A Retrospective Clinical Study of Stereotactic Body Radiotherapy Combined With PD-1 Blockers for Locally Advanced or Locally Recurrent Pancreatic Carcinoma.

The goal of this observational study is to investigate the efficacy and safety of stereotactic body radiotherapy combined with PD-1 blockers for LAPC and LRPC. The patients, diagnosed with locally advanced pancreatic cancer (LAPC) or locally recurrent pancreatic cancer (LRPC). LRPC or LAPC, undergoing SABT and PD-1 blockers in our hospital from December 2020 to April 2023 were reviewed consecutively. All patients provided written informed consent before treatment. The study was conducted in accordance with the Declaration of Helsinki, and it was approved by the Institutional Ethics Committee of Peking University Third Hospital.

Read the detailed description

The goal of this observational study is to investigate the efficacy and safety of stereotactic body radiotherapy (SBRT) combined with PD-1 blockers for LAPC and LRPC. The patients, diagnosed with locally advanced pancreatic cancer (LAPC) or locally recurrent pancreatic cancer (LRPC). LRPC or LAPC, undergoing SBRT and PD-1 blockers in our hospital from December 2020 to April 2023 were reviewed consecutively. The schedule of SBRT is 25 to 50 Gy in 5 fractions and the PD-1 blockers are monoclonal antibodies targeted to PD-1 molecules on the T lymphocytes.

All patients provided written informed consent before treatment. The study was conducted in accordance with the Declaration of Helsinki, and it was approved by the Institutional Ethics Committee of Peking University Third Hospital.

Being tested
Stereotactic body radiotherapy (SBRT), PD-1 blocking antibody
Medical subject headings
Pancreatic Neoplasms

What participants receive

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

  • Stereotactic body radiotherapy (SBRT)Radiation

    All the patients first received SBRT with the dose of 25Gy up to 50Gy in five fractions.

  • PD-1 blocking antibodyDrug

    All the patients first received SBRT with the dose of 25Gy up to 50Gy in five fractions and then received the treatment of PD-1 blockers including pembrolizumab (200 mg every 3 weeks), carelizumab (200 mg every 3 weeks), tislelizumab (200 mg every 3 weeks), sintilimab (200 mg every 3 weeks), zimberelimab (240 mg every 3 weeks) until the tumor progressed or the side effects became intolerable.

What is being measured

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

  1. progression-free survival (PFS)

    PFS was defined as the time from SBRT to disease progression

    Measured: 12 months

Secondary outcomes (4)
  1. local progression-free survival (LPFS)

    LPFS was defined as the time from SBRT to local progression.

    Measured: 12 months

  2. Overall survival (OS)

    OS was defined as the time from SBRT to death from any cause.

    Measured: 18 months

  3. Adverse Events (AEs)

    All kinds of side effects.

    Measured: 18 months

  4. Pain relief rate (PRR)

    The numeric rating scale (NRS) was used to evaluate the pain levels before and after treatment and the pain relief rate was calculated from the patients achieving pain The numeric rating scale (NRS) was used to evaluate the pain levels before and after treatment and the pain relief rate was calculated from the patients achieving pain The numeric rating scale (NRS) was used to evaluate the pain levels before and after treatment and the pain relief rate was calculated from the patients achieving pain relief after SBRT.

    Measured: 18 months

Questions about this trial

What is this clinical trial studying?

An observational study of Stereotactic Body Radiotherapy and PD-1 Inhibitors, run by Peking University Third 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 5 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: finished, as of the sponsor's last update on 8 Jan 2024. 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?

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 (PFS) (time frame: 12 months). 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 8 Jan 2024.
