About this study
Official title: Study of Pharmacokinetic, Safety, Immunogenicity and Efficacy of CMAB819 and Nivolumab in Recurrent or Metastatic Squamous Cell Carcinoma of the Head and Neck
The purpose of this study is to compare the pharmacokinetic, safety, immunogenicity and efficacy of CMAB819 and Nivolumab in subjects with recurrent or metastatic head and neck squamous cell carcinoma., after failure of prior platinum-based chemotherapy.
Read the detailed description
Patients were randomized to receive CMAB819 or Nivolumab 480 mg by intravenous infusion every 4 weeks until documented disease progression, discontinuation, withdrawal of consent, or up to 4 doses in subjects without disease progression, whichever occurs earlier. After completing 4 doses of therapy, administer of CMAB819 480 mg intravenous (IV) solution for injection every 4 weeks until documented disease progression, discontinuation, withdrawal of consent or the study ends. Randomization was stratified by Eastern Cooperative Oncology Group (ECOG) performance status ECOG (0 versus 1), sex (male versus female), weight （≤60 kg versus >60kg）and clinical trial institution (up to 20 centers) .

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing CMAB819 and Nivolumab in people with Squamous Cell Carcinoma of the Head and Neck, run by Taizhou Mabtech Pharmaceutical Co.,Ltd 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 14 inclusion and 17 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: stopped early, as of the sponsor's last update on 9 Apr 2024. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was stopped early (reason given: Difficult to recruit subjects). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
AUC0-4w,1 (time frame: Day 1 to Day 29). 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 9 Apr 2024; AzTrials last refreshed its copy on 8 Nov 2026.
