A Phase 2 Study of Toripalimab in Combination With Cisplatin and Docetaxel (PDT) for Induction Therapy in CPS-Positive Locally Advanced Head and Neck Squamous Cell Carcinoma
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).
• 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%
• Age ≥18 years. Because no dosing or adverse event data are currently available on the use of toripalimab in combination with cisplatin and docetaxel in participants \<18 years of age, children are excluded from this study, but will be eligible for future pediatric trials.
• ECOG performance status ≤ 1
• Life expectancy of greater than 12 weeks.
• Participants must meet the following organ and marrow function as defined below:
⁃ Hemoglobin ≥8.0 g/dL absolute neutrophil count ≥1500/mcL platelets ≥100,000/mcL total bilirubin ≤ 2 institutional upper limit of normal (ULN) AST(SGOT)/ALT(SGPT) ≤ 2 × institutional ULN creatinine ≤ 2 x institutional ULN OR glomerular filtration rate (GFR) ≥ 45 mL/min/1.73 m2
• Participants with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial.
• Because immunotherapy agents as well as cisplatin and docetaxel are known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 4 months after completion of toripalimab administration.
• Ability to understand and the willingness to sign a written informed consent document.
