About this study

Official title: PD-1 Antibody for the Prevention of Adenomatous Polyps and Second Primary Tumors in Patients With Lynch Syndrome: An Open-label, Multicenter, Randomized Controlled Clinical Trial

This study aims to explore the role of PD-1 Antibody in preventing adenomatous polyps and second primary tumors in patients with Lynch Syndrome. There two arms, one is the experimental arm (PD-1 antibody prevention group) and the other is the control arm (routine follow-up group). For the experimental group, Tripleitriumab (PD-1 antibody) is given every 3 months for a year.

Read the detailed description

Lynch syndrome (LS) is a hereditary cancer syndrome that causes the majority of hereditary CRC and approximately 3% of all CRC. LS significantly increases the risk for an individual to develop CRC during their lifetime. Individuals with LS also have an increased risk to develop extracolonic cancers, including endometrial, gastric, ovarian, upper urinary tract, small bowel, biliary tract, CNS, and certain types of skin cancer. Given the hereditary nature of this syndrome, preventing second primary tumors in patients with Lynch Syndrome after surgery to the primary site is very important.

The purpose of this study is to prevent adenomatous polyps and second primary tumors using PD-1 antibody (Tripleitriumab) in patients with Lynch Syndrome.

The primary outcome of this study is the incidence of intestinal adenomatous polyps and secondary primary tumors. The secondary outcomes are the incidence of colorectal adenomatous polyps greater than 1cm, incidence of high-grade colorectal polyps, treatment-related adverse events, disease-free Survival and overall Survival.

There are two groups: the PD-1 antibody prevention group and the routine follow-up group. For the PD-1 antibody prevention group, participants will receive Toripalimab 240mg IV every 3 months for a year. For the routine follow-up group, there is no drug intervention.

This whole study will take 5 years: the first year for recruiting and the latter four years for follow-up.

What is being measured

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

  1. The percentage of patients from randomization to the first appearance of one of the following: adenomatous polyps or second primary tumors

    Measured: up to 5 years

Secondary outcomes (6)
  1. The percentage of patients developing polyps greater than 1cm within 5 years from randomization

    Measured: up to 5 years

  2. The percentage of patients developing high-grade polyps on pathology within 5 years from randomization.

    Measured: up to 5 years

  3. Treatment-related adverse events

    Incidence and severity of adverse events as assessed by NCI CTCAE V4.0

    Measured: up to 5 years

  4. Effectiveness with different genotypes or phenotypes

    Estimated the percentage of patients with different genotypes or phenotypes not developing polyps or second primary tumors within 5 years from randomization.

    Measured: up to 5 years

  5. Disease-free Survival

    defined as the time from randomization to the first appearance of one of the following: primary tumor recurrence, or death without cancer event; or censored at date of last follow-up

    Measured: up to 5 years

  6. Overall Survival

    defined as the time from randomization to death from any cause. Participants who were alive or lost to follow-up at the time of the analysis were censored at the date they were last known to be alive

    Measured: up to 5 years

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing PD-1 Antibody in people with Lynch Syndrome, run by Sun Yat-sen University 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 8 inclusion and 13 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: status not confirmed, as of the sponsor's last update on 20 Jan 2021. 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Peirong Ding, MD, Ph D (00862087343124, dingpr@sysucc.org.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The percentage of patients from randomization to the first appearance of one of the following: adenomatous polyps or second primary tumors (time frame: up to 5 years). 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 20 Jan 2021.
