About this study

Official title: Safety and Efficacy of Cadonilimab Combined With Anlotinib in Neoadjuvant Treatment of Locally Advanced Resectable Esophageal Squamous Cell Carcinoma: a Single Arm, Phase II Study

The goal of this clinical trial is to learn if cadonilimab combined with anlotinib can be a safe and effective neoadjuvant therapy in patients with locally advanced resectable esophageal squamous cell carcinoma (ESCC). The main questions it aims to answer are:

What level of pathological complete response (pCR) rate can be achieved with this neoadjuvant regimen? Is this neoadjuvant regimen safe enough with acceptable toxicity?

Read more

Participants will:

Receive cadonilimab (10mg/Kg, ivgtt, d1) and anlotinib (12mg, P.O., d1-d14) on a 21-day regimen for 3 cycles.

Undertake radical resection of ESCC after neoadjuvant therapy if there is no surgical contraindication.

Accept an follow-up for 2 years after surgery.

Read the detailed description

Esophageal cancer has a high incidence in China, among which esophageal squamous cell carcinoma is the most common. Neoadjuvant chemoradiotherapy combined with surgery is currently the recommended treatment modality for locally advanced esophageal cancer, but the side effects of chemoradiotherapy are serious, which increases the risk of surgery.

Immune checkpoint inhibitors have made significant progress in the field of cancer treatment in recent years, and have now become an important treatment method for advanced and metastatic esophageal cancer. Several trials on neoadjuvant immuno-chemotherapy demonstrated better outcomes with acceptable toxicity compared to traditional chemoradiotherapy. Cadonilimab is a dual immune antibody drug comprised of PD-1 antibody and CTLA-4 antibody, which has the anti-tumor effect of two immune checkpoint pathways at the same time.

On the other hand, angiogenesis plays a vital role in the growth and metastasis of tumors, and anti-angiogenic drugs have become an important part of cancer treatment. Anlotinib is an oral, small molecule anti-angiogenic targeted agent that has been approved for use in a variety of cancer treatments.

This study plans to conduct a prospective study of cadonilimab combined with anlotinib in the neoadjuvant treatment of resectable esophageal squamous cell carcinoma, and aims to explore the efficacy and safety of this neoadjuvant regimen that avoids chemoradiotherapy in locally advanced resectable esophageal squamous cell carcinoma.

What is being measured

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

  1. Pathological Complete Response (pCR) Rate

    Pathological complete response (pCR) rate is defined as the percentage of participants with no residual viable tumor in primary tumor site or lymph nodes as evaluated by blinded independent pathological review (BIPR).

    Measured: Within 1 week after surgery

Secondary outcomes (4)

  1. Major Pathological Response (MPR) Rate

    Major pathological response (MPR) rate is defined as the percentage of participants with less than or equal to 10% of residual viable tumor in primary tumor site or lymph nodes as evaluated by blinded independent pathological review (BIPR). Viable tumors in situ carcinoma should not be included in MPR calculation.

    Measured: Within 1 week after surgery

  2. Objective Response Rate (ORR)

    Objective response rate (ORR) is defined as the Percentage of participants achieving complete response (CR) or partial response (PR) in all patients with measurable disease at baseline, as assessed by the investigator according to RECIST version 1.1.

    Measured: Within 1 week before surgery

  3. Treatment Emergent Adverse Events (TEAE)

    The incidence and severity of treatment emergent adverse events (including adverse events, serious adverse events and immune-related adverse events) among all participants.

    Measured: Up to 24 months after participation

  4. Event-free Survival (EFS)

    EFS is defined as the time from participation to any of the following events: progression of disease, recurrence disease, or death due to any cause. Progression/recurrence will be assessed either by biopsy assessed by local pathologist or by investigator-assessed imaging using RECIST version 1.1.

    Measured: Up to 24 months after participation

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Cadonilimab plus anlotinib in people with Locally Advanced Esophageal Squamous Cell Carcinoma, run by Peking University People's Hospital.

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 19 inclusion and 40 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: opening soon, as of the sponsor's last update on 23 May 2024. Status can change between updates, so confirm with the study contact before making plans.

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?

This study is still under way. Results are not available in the source record yet.

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

Contact Fan Yang, M.D. (+86-010-88326657, yangfan@pkuph.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pathological Complete Response (pCR) Rate (time frame: Within 1 week after surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06426797.

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 23 May 2024.
