Clinical Trial Summary

Previous studies confirmed locally advanced oral/oropharyngeal squamous cell carcinoma (LA OSCC or OPSCC) patients with a pathological response had higher probability of survival in neoadjuvant settings. Several ongoing trials of neoadjuvant immunotherapy in head and neck cancer showed promising results. However, the optimal regimen remains unclear. This trial aimed to evaluate the efficacy and safety of neoadjuvant therapy with anti-programmed cell death 1 monoclonal antibody Tislelizumab and chemotherapy, followed by surgery and adjuvant radiotherapy or chemoradiotherapy plus Tislelizumab in LA OSCC or OPSCC.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Rate of Event free survival (EFS) at 2 years	EFS is the time from the date of randomization to the date of first record of any of the following events: disease progression; local or distant recurrence as assessed with imaging or biopsy as indicated; or death due to any cause.	Up to 2 years
Secondary	Major Pathological Response (mPR)	The proportion of participants with a major pathological response (mPR) as assessed by the Central Pathologist at the time of definitive surgery. mPR is defined as =10% invasive squamous cell carcinoma within the resected primary tumor specimen and all the sampled regional lymph nodes.	Up to 30 days post-surgery
Secondary	Pathological Complete Response (pCR)	Pathological complete response (pCR) is measured as the proportion of participants with a pathological complete response as assessed by the central pathologist at the time of definitive surgery. pCR is defined as having no residual invasive squamous cell carcinoma within the resected primary tumor specimen and all sampled regional lymph nodes.	Up to 30 days post-surgery
Secondary	Overall response rate (ORR)	Overall response rate (ORR) is defined as the percentage of participants in the analysis population who have a Complete Response (CR: Disappearance of all target lesions) or a Partial Response (PR: At least a 30% decrease in the sum of diameters of target lesions) per Response Evaluation Criteria in Solid Tumors (RECIST 1.1) criteria.	UP to 30 days prior-surgery
Secondary	Overall survival (OS)	OS is the time from randomization to death due to any cause.	Up to 2 years
Secondary	Adverse events (AEs)	Number of participants experiencing any sign, symptom, disease, or worsening of preexisting conditions temporally associated with the experimental interventions or irrespective of the experimental interventions per NCI-CTCAE V5.0.	Up to 2 years
