Clinical Trial Comparing Induction Treatment With EGFR-ADC MRG003 Alone or in Combination With the Anti PD1 Pucotenlimab, Followed by Radiochemotherapy in Locally Advanced Squamous Cell Cancers of the Head and Neck

France106 participantsStarted 2025-10-13

Plain-language summary

The primary objective of this study is to compare the objective response rate (ORR) of patients with LA-HNSCC, treated with induction of EGFR-ADC MRG003 and anti PD-1 Pucotenlimab versus EGFR-ADC MRG003 alone before chemoradiotherapy. People eligible to participate in this study must be between the ages of 18 and 75 and have locally advanced squamous cell carcinoma of the head and neck requiring treatment with chemoradiotherapy (cisplatin combined with radiotherapy). Half of the research participants will receive MRG003 alone as induction before radiochemotherapy and the other half will receive MRG003 combined with pucotenlimab as induction before radiochemotherapy, then pucotenlimab as adjuvant\* after radiochemotherapy.

Exclusion Criteria: * Metastatic disease (stage IVC as per AJCC/TNM, 8th Ed.). * Patients having received prior therapy with anti-PD1, anti-PD-L1, anti-PD-L2, anti- CD137, or anti-CTLA-4 antibody (or any other antibody or drug specifically targeting Tcell co-stimulation or checkpoint pathways). * Treatment for other diseases with an investigational agent or use of an investigational device within 4 weeks of the first dose of study treatment * History of another malignancy within the last 3 years prior to randomization, with the exception of completely resected non-melanoma cell skin cancer outside the head and neck area or completely resected stage I breast cancer, or completely resected in-situ nonmuscular invasive bladder, cervix, uterine and/or prostate (Gleason 6) carcinomas, or T1a squamous cell carcinoma of the esophagus or rectum/anus. * Patients with clinically significant (i.e., active) cardiovascular disease: cerebral vascular acci…

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
