This study focuses on treating recurrent or metastatic head and neck squamous cell carcinoma, a type of cancer that has either come back after initial treatment or spread to other parts of the body. The research evaluates a combination treatment using two medications: ficerafusp alfa (also known as BCA101) and pembrolizumab (KEYTRUDA). These medications are given through intravenous infusion, which means they are delivered directly into the bloodstream through a vein.
The purpose of the study is to determine if adding ficerafusp alfa to pembrolizumab works better than pembrolizumab with placebo for patients who have not received previous treatment for their advanced cancer. The study will test two different doses of ficerafusp alfa (750 mg and 1500 mg) to find the most effective and safest dose when combined with pembrolizumab.
During the treatment, participants will receive regular doses of the study medications for up to 24 months. The study will track how well the treatment works by measuring if the cancer shrinks or disappears (tumor response), how long patients live (overall survival), and how long patients live without their cancer getting worse (progression-free survival). The study will also monitor any side effects that participants may experience during treatment.
1Initial treatment assignment
After joining the study, you will be randomly assigned to one of three treatment groups:
– Group A: ficerafusp alfa 1500 mg with pembrolizumab
– Group B: ficerafusp alfa 750 mg with pembrolizumab
– Group C: placebo with pembrolizumab
2Treatment administration
You will receive medication through intravenous infusion (directly into your vein)
The treatment will be given once weekly
Both medications (ficerafusp alfa and pembrolizumab) will be administered as a solution for infusion
3Medical monitoring
Your health will be regularly monitored through:
– Blood tests to check organ function
– Imaging scans to measure tumor response
– Assessment of any side effects
Your doctor will track if the cancer is responding to treatment using standardized measurement criteria (RECIST 1.1)
4Quality of life assessment
You will complete questionnaires about:
– Your overall health status
– Quality of life
– Pain levels related to head and neck cancer
5Study duration
The study is expected to run from November 2025 to July 2029
Your participation length will depend on how your cancer responds to treatment
Treatment will continue until either your disease progresses or you experience unacceptable side effects

Ficerafusp alfa is a new investigational medication being studied for treating head and neck cancer. It is designed to work together with another medication to help fight cancer cells. It is administered once weekly through an intravenous infusion.
Pembrolizumab is an immunotherapy medication that helps the body’s immune system detect and fight cancer cells. It works by blocking a protein called PD-L1 that cancer cells use to hide from the immune system. It is given through an intravenous infusion.
Head and Neck Squamous Cell Carcinoma – A type of cancer that begins in the squamous cells lining the moist surfaces inside the head and neck regions. It typically starts in the mouth, throat, or voice box and can spread to nearby tissues. The cancer forms when squamous cells develop genetic changes, causing them to grow uncontrollably and form tumors. When described as recurrent, it means the cancer has returned after treatment, while metastatic indicates the cancer has spread to other parts of the body beyond its original location.
