About this trial
This research study is being done to assess the safety and tolerability of toripalimab in combination with cisplatin and docetaxel (PDT) induction therapy for patients with CPS-positive locally advanced head and neck squamous cell carcinoma (HNSCC).
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Participants must have a new diagnosis of histologically or cytologically confirmed squamous cell carcinoma (SCC) of the oral cavity, oropharynx, hypopharynx, larynx, nasopharynx, sinonasal cavities or unknown primary HNSCC.
Participants with HPV-independent SCC or HNSCC or other head and neck subsites must have stage III or non-metastatic stage IV at the time of diagnosis. Participants with HPV-associated oropharynx SCC must have stage II or stage III disease.
Participants must be determined by the investigator to be candidates for induction systemic therapy due to reasons such as the extent of primary tumor at the time of diagnosis, rate of progression, symptom burden or potential benefit of cytoreduction prior to definitive local therapy.
CPS ≥ 1%
Disqualifiers
Diagnosis of EBV-associated nasopharynx squamous cell carcinoma
Strong clinical suspicion or histologic confirmation of cutaneous squamous cell carcinoma
Histology other than squamous cell carcinoma.
Proven distant metastases (below the clavicle) by clinical or radiographic measures.

DrugDocetaxel is a taxane chemotherapy agent.
Treatment groups
Trial outcomes
Primary outcomes
Proportion Grade 3-5 TRAE-free during induction therapy
Assessed using NCI Common Terminology for Adverse Event (CTCAE) version 5.0. The rate of patients with grade 3+ TRAEs-free during induction therapy will be summarized as a proportion with a corresponding exact 95% confidence interval (CI) (if the trial closes to accrual after the first stage), or a proportion with a corresponding 95% two-stage confidence interval (CI) if the trial closes to accrual after the second stage.
Secondary outcomes
Proportion Grade 3-5 TRAE-free during curative-intent treatment
Assessed using NCI Common Terminology for Adverse Event (CTCAE) version 5.0. The rate of participants grade 3+ TRAEs-free during the entire period of curative-intent treatment will be summarized as a proportion with a corresponding exact 95% confidence interval (CI) (if the trial closes to accrual after the first stage), or a proportion with a corresponding 95% two-stage confidence interval (CI) if the trial closes to accrual after the second stage.
Overall Response Rate (ORR) after PDT induction therapy
The overall response rate (ORR) will be summarized as a proportion with a corresponding exact 95% two-stage confidence interval (CI).
Overall Response Rate (ORR) after curative-intent therapy
The overall response rate (ORR) will be summarized as a proportion with a corresponding exact 95% two-stage confidence interval (CI).
Event-free Survival
The Kaplan-Meier method will be used to estimate time-to-event endpoints with corresponding 95% confidence intervals (CIs) for the median or time-specific event time.
