Exclusion Criteria

  1. Prior treatment for head and neck cancer 2. Unresectable laryngeal or hypopharyngeal squamous cell carcinoma 3. Distant metastatic disease 4. Has an active autoimmune disease requiring systemic treatment within the past 3 months, or a syndrome that requires ongoing systemic steroids or immunosuppressive agents. Subjects with vitiligo, Grave's disease, or psoriasis not requiring systemic therapy or resolved childhood asthma/atopy would be an exception to this rule. Subjects that require intermittent use of bronchodilators or local steroid injections would not be excluded from the study. Subjects with hypothyroidism or Sjogren's syndrome will not be excluded from the study. 5. Has a history of non-infectious pneumonitis that required steroids, evidence of interstitial lung disease, or currently active non-infectious pneumonitis. 6. Known allergy or hypersensitivity to carboplatin or cisplatin, toripalimab, or paclitaxel. 7. Prior malignancy within 2 years that in the investigator's opinion would be likely to affect the outcomes for the patient. 8. Peripheral sensory neuropathy > grade 2 by CTCAE v5.0 9. Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject's participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator. 10. Has acute or chronic active hepatitis B and C virus infection or known history of untreated hepatitis B (defined as hepatitis B surface antigen [HBsAg] reactive) or known active hepatitis C virus (HCV) (defined as HCV RNA [qualitative]) or HIV infection (see note). 1. Note: No testing for Hepatitis B, Hepatitis C, or HIV is required unless mandated by local health authority or clinically indicated. 2.

Detailed Description

Currently, for patients with locally advanced laryngeal or hypopharyngeal squamous cell carcinoma (SCC), there is the option of total laryngectomy (TL) followed by adjuvant pathology driven therapy (RT or CRT) or an organ preservation approach. Total laryngectomy is a particularly morbid surgery, leaving a patient breathing through the neck for the rest of their life. In recent years however, upfront total laryngectomy with adjuvant RT has been in focus to growing concern of reduced overall survival rates in advanced laryngeal and hypopharyngeal SCC, particularly in patients with T4 disease. As such, upfront TL with adjuvant RT or CRT is typical, with organ preservation protocols more controversial, for T4 LSCC specifically. This trial provides neoadjuvant (chemo)immunotherapy (induction regimen of platinum (carboplatin or cisplatin), paclitaxel, and toripalimab) allowing for a novel approach to patient bioselection for the treatment of laryngeal cancer. Toripalimab is approved in combination with cisplatin and gemcitabine for the first-line treatment of patients with recurrent and/or metastatic nasopharyngeal carcinoma and has shown to significantly improved PFS and OS when combined with cisplatin and gemcitabine. Patients who show response to neoadjuvant therapy in laryngeal cancer have been shown to have 1) a better survival than patients who do not respond and 2) respond better to nonsurgical therapy. The addition of immunotherapy to chemotherapy has the potential to improve the response rate to neoadjuvant therapy, decrease the number of patients who require total laryngectomy as their primary treatment, and to improve the survival of patients with this highly morbid disease.
