Trial overview
This clinical trial is studying LIGUFALIMAB in people with recurrent and/or metastatic squamous cell carcinoma of the head and neck.[1] The study is designed to compare treatment options in the first-line setting, which means the first treatment given for this cancer.[1]
The trial is interventional, so researchers actively assign the treatments being tested rather than only observing what happens naturally.[1] The planned enrollment is 700 participants.[1]
Who can participate
The study targets patients with recurrent and/or metastatic squamous cell carcinoma of the head and neck.[1] It also focuses on patients with PD-L1 positive disease, defined in the trial as CPS ≥ 1.[1]
Recurrent means the cancer has come back after treatment.[1] Metastatic means the cancer has spread to other parts of the body.[1] PD-L1 positive and CPS are test results used to describe the tumor and help identify the study population.[1]
Treatments being compared
The trial compares ivonescimab alone or ivonescimab with LIGUFALIMAB against pembrolizumab, which is listed in the trial as KEYTRUDA.[1] The study summary says the goal is to compare these strategies as first-line treatment for the target cancer group.[1]
The interventions are given by intravenous infusion, meaning the treatment is delivered into a vein.[1] The trial record lists LIGUFALIMAB at 45 mg/kg and ivonescimab at 10 mg/kg.[1]
Trial phase and status
This study is in Phase 3.[1] Phase 3 trials usually compare a new or tested approach with standard care in a larger group of patients, to see which option performs better.[1]
The status of the trial is Authorised.[1] This means the study has been approved to proceed according to the information in the trial record.[1]
Main endpoint
The main endpoint is overall survival.[1] Overall survival means the length of time patients live after starting the study treatment.[1]
This endpoint is important because it shows whether one treatment strategy helps people live longer than another.[1] In this trial, overall survival is used to compare ivonescimab with or without LIGUFALIMAB against pembrolizumab.[1]
What this means for patients
For patients, this trial is mainly about finding the best first treatment for a serious head and neck cancer that has come back or spread.[1] The study includes a specific subgroup of patients whose tumors are PD-L1 positive, which helps define who may take part.[1]
Because it is a Phase 3 study with a large enrollment target, the results may help show whether the tested treatment strategy can improve survival compared with the current standard option.[1]
