About this study

Official title: Cadonilimab as Neoadjuvant Therapy in Resectable Stage II-III Mismatch Repair-deficient (dMMR)/ Microsatellite Instability-high (MSI-H) Colorectal Cancer

This study will evaluate the safety, and tolerability of Cadonilimab as neoadjuvant treatment for resectable local advanced colorectal cancer patient with dMMR/MSI-H.

Read the detailed description

Colorectal cancer (CRC) is one of the most common malignant tumours of human beings. Mismatch Repair-deficient (dMMR)/ Microsatellite Instability-high (MSI-H) CRC is a specific subtype of CRC, which accounts for approximately 15% ~20% of all CRC patients,and can not benefit from 5-fluorouracil (5-FU) adjuvant chemotherapy. Once patients have distant metastases, they are not sensitive to traditional palliative chemotherapy, and thus lead to much worse prognosis than that of mismatch repair-proficient (pMMR)/ microsatellite stability (MSS). Neoadjuvant immunotherapy based on mismatch repair (MMR) status in CRC have reported some encouraging data. The NICHE study showed that 20 CRC patients with dMMR achived pathological remission, of which 19 patients with residual tumor ≤10%, 15 patients achived pathological complete remission. Another study (ClinicalTrials.gov, NCT03926338) which investigating the effect of neoadjuvant PD-1 blockade with toripalimab, with or without celecoxib, on mismatch repair-deficient or microsatellite instability-high, locally advanced, colorectal cancer. The result revealed that all 34 patients had an R0 resection. 15 of 17 patients (88%) in the toripalimab plus celecoxib group and 11 of 17 patients (65%) in the toripalimab monotherapy group had a pathological complete response.

Cadonilimab (®), a PD-1/CTLA-4 bi-specific antibody, is being developed by Akeso, Inc. for the treatment of a range of solid tumours, including cervical cancer, lung cancer, gastric/gastroesophageal junction cancer, oesophageal squamous cell cancer, liver cancer and nasopharyngeal cancer. Cadonilimab was approved in China in June 2022 for use in patients with relapsed or metastatic cervical cancer (r/mCC) who have progressed on or after platinum-based chemotherapy.

Given the reported efficacy data about immunotherapy as neoadjuvant treatment in MSI-H/dMMR CRC, the aim of this study was to investigate the efficacy and safety of Cadonilimab as neoadjuvant treatment for resectable local advanced colorectal cancer patient with the dMMR/MSI-H.

What is being measured

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

  1. Pathological complete response (pCR) rates

    Proportion of patients experiencing a pCR to perioperative PD-1/CTLA-4 bi-specific antibody

    Measured: 1 year

Secondary outcomes (5)
  1. Major pathological response rates

    The proportion of patients experiencing a major pathological response to perioperative PD-1/CTLA-4 bi-specific antibody

    Measured: 1 year

  2. R0 resection rates

    The proportion of patients experiencing a R0 resection after perioperative treatment with PD-1/CTLA-4 bi-specific antibody

    Measured: 1 year

  3. Relapse-free survival (DFS)

    Defined as the time from radical surgery to relapse, metastasis or death from any cause

    Measured: 3 years

  4. The incidence of Treatment-related Adverse Events

    Assessed by evaluation of treatment-related adverse events

    Measured: 1 year

  5. Number of participants with any treatment-related delays in the planned surgery of no more than 28 days after the last preoperative Cadonilimab dose

    Any treatment-related delays in the planned surgery of no more than 28 days after the last preoperative Cadonilimab dose

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Cadonilimab (®), a PD-1/CTLA-4 bi-specific antibody in people with Colorectal Cancer and Mismatch Repair-deficient (dMMR), run by LiuYing 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 20 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 22 Jun 2023. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 Ying Liu, MD (+86-13783604602, Yaya7207@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pathological complete response (pCR) rates (time frame: 1 year). 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 22 Jun 2023.
