Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: All tumor patients who are initiating the chemotherapy in The Second Affiliated Hospital, Zhejiang University School of Medicine (SAHZU) and willing to join this cohort study after the date of recruiting (19th Sep 2022). These patients who are eligible for the inclusion criteria would be the targets for further follow-up.

Who may be able to join

  • Subjects know about the experiment and signed the informed consent voluntarily; and
  • Subjects are tumor patients and all kinds of tumor diseases of subjects are acceptable; and
  • Subjects are initiating to receive chemotherapy; and
  • Subjects are diagnosed with atherosclerotic carotid plaques by ultrasound examination at the timepoint of the first-dose treatment; and

Who cannot join

  • Subjects stop receiving or changing the existing chemotherapy during follow-up; or
  • Subjects are reluctant to continue to be involved in this study; or
  • Subjects are known pregnant and lactating women; or
  • Subjects are not complicated with atherosclerotic carotid plaques at the timepoint of the first-dose treatment; or
  • 4. The parameters (e.g., CCA intima-media, ICA intima-media, or carotid plaque area) could not be calculated because of the quality of the ultrasound image; or 5. Other situations that the researchers judged are not suitable for further inclusion.

About this study

Official title: Single-center, Prospective Cohort Study of PD-1inhibitors on Clinical Outcomes of Carotid Plaques in Tumor Patients

This is a single-center, prospective cohort study on the comparison of clinical outcomes of carotid plaques in PD-1-treated tumor patients vs non-PD-1-treated tumor patients.

Read the detailed description

Atherosclerosis, a chronic inflammatory disorder, leads to cardio-cerebrovascular diseases, causing most of the global deaths. The chronic and non-resolved inflammatory responses of both innate and adaptive immune cells are involved in the all-stage pathogenesis of atherosclerosis. The impairment of inflammatory resolution promotes atherogenesis and causes instability of atherosclerotic plaques. Their subsequent rupture would induce severe cardio-cerebrovascular incidences (e.g., acute myocardial infarction and ischemic strokes). Recent progress in anti-inflammatory immunotherapies on human atherosclerosis opens the door to resolving this inflammatory disorder by targeting the immune system. However, the impacts of PD-1 immune checkpoint blockades on the progressions of human carotid plaques are not determined yet.

This is a prospective cohort study, which aims to evaluate the effectiveness of PD-1 immune checkpoint blockades on atherosclerotic carotid plaques in tumor patients in comparison to those with non-PD-1-treated tumor patients. The method for quantification and evaluation of atherosclerotic plaques are based on: (1) the mean intima-media thickness of the common carotid artery (Mean CCA thickness); (2) the maximum intima-media thickness of the internal carotid artery (maximum ICA thickness); (3) Carotid plaque areas: by calculation of the plaque area of atherosclerotic plaques on the long axis direction of artery on the ultrasound images. By comparing the above-mentioned parameters at the same location of the carotid artery in the patients when initiating the first dose of anti-PD-1 or non-PD-1 chemotherapy and 3 months after anti-PD-1 or non-PD-1 chemotherapy. It is designed to assess the effectiveness of PD-1 immune checkpoint blockades or non-PD-1 chemotherapy on the clinical prognosis of carotid plaques after a period of 3-month treatment.

What participants receive

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

  • PD-1 inhibitorDrug

    Also called PD-1 immune checkpoint blockades

    PD-1 inhibitor is defined as the exposure factor in our cohort study, for the tumor patients with the treatment of PD-1 inhibitor are allocated to the Exposure group whereas those tumor patients without the treatment of PD-1 inhibitor are allocated to the Non-exposure group.

Study groups in NCT05549336
Study groupRoleWhat they receive
PD-1-treated tumor patientsTumor patients who are initiating receive chemotherapy that includes PD-1 inhibitors.
Receives: Drug: PD-1 inhibitor
non-PD-1-treated tumor patientsTumor patients who are initiating receive chemotherapy that not includes PD-1 inhibitors.

What is being measured

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

  1. Carotid plaque area

    Carotid plaque area measured by ultrasound (cross-sectional area of longitudinal views of all plaques seen) to quantify the increase or decrease of atherosclerotic carotid plaques.

    Measured: 3 months

  2. The mean intima-media thickness of the common carotid artery

    It was measured over a segment of the common carotid artery that was 1 cm long, located approximately 0.5 cm below the carotid-artery bulb, and considered not to contain any plaque (i.e., not to have any perceivable protrusion of the artery wall into the lumen).

    Measured: 3 months

  3. The maximum intima-media thickness of the internal carotid artery

    It was defined as the greatest intima-media thickness in either the right or left internal carotid artery extending from the bulb to 1 cm above the carotid sinus, ascertained from a total of four views on each side.

    Measured: 3 months
