Neoadjuvant Chemoimmunotherapy Followed By Radiation Or Organ Preservation Surgery In Laryngeal/Hypopharyngeal Cancer

Recruiting now · Phase 2

Conditions studied: Larynx Cancer, Hypopharyngeal Cancer

In brief

In the global landscape of cancer, head and neck malignancies are highly prevalent, with 878,000 new cases and 444,000 deaths recorded in 2020. Notably, laryngeal and hypopharyngeal cancers contribute to around 30% of these instances. More than 50% of patients are diagnosed with locally advanced disease, necessitating intensive treatments that significantly impact their quality of life. Despite these efforts, the prognosis for laryngeal and hypopharyngeal cancers remains grim, with a 5-year survival rate of 30% to 50%. Past approaches focused on preserving laryngeal function and patient well-being, including minimally invasive surgery, advanced radiotherapy, and induction chemotherapy. Our prior research highlighted the effectiveness of combining toripalimab-based induction therapy and chemotherapy, followed by concurrent chemoradiotherapy or surgery. Positive short-term outcomes and manageable side effects were observed, with encouraging larynx preservation rates after one year. Against this backdrop, the current study aims to explore neoadjuvant immunotherapy combined with chemotherapy for patients with locally advanced laryngeal and hypopharyngeal cancer. It seeks to compare the therapeutic efficacy and quality of life impacts of concurrent radiochemotherapy and organ-preserving surgery. The ultimate goal is to identify optimal strategies for future interventions.

Presence of at least one measurable lesion before treatment, in accordance with RECIST 1.1 criteria for "measurable lesions."
Patients who have received neoadjuvant immunotherapy combined with chemotherapy and have achieved a partial response (PR) in the primary lesion according to RECIST 1.1 criteria and are suitable candidates for organ preservation surgery.
Expected survival of more than 3 months.
Eastern Cooperative Oncology Group (ECOG) performance status score of 0-1.
Good organ function, meeting the following criteria:
Absolute neutrophil count (ANC) ≥1.5×10\^9/L.
Platelet count ≥100×10\^9/L.
Hemoglobin ≥9 g/dL.
Serum albumin ≥2.8 g/dL.
Total bilirubin ≤1.5× upper limit of normal (ULN), ALT, AST, and/or ALP ≤3× ULN.
Serum creatinine ≤1.5× ULN and creatinine clearance ≥60 mL/min (Cockcroft-Gault formula, see Appendix III).
Activated partial thromboplastin time (APTT) and international normalized ratio (INR) ≤1.5× ULN (patients on stable doses of anticoagulation with agents like low molecular weight heparin or warfarin, and INR within the expected therapeutic range, may be included).
Patients with hepatitis B virus (HBV) infection, inactive/asymptomatic HBV carriers, or patients with chronic or active HBV infection with HBV DNA <500 IU/mL (or 2500 copies/mL) at screening will be allowed to participate. Patients positive for hepatitis C antibodies, if HCV-RNA is negative at screening, will be allowed to participate.
Females of childbearing potential must have a negative pregnancy test result in urine or serum ≤7 days before treatment initiation. They must use a medically accepted contraceptive measure (such as intrauterine device, oral contraceptives, or condoms) during the study treatment period, for at least 3 months after the last dose of toripalimab, and for at least 6 months after the last dose of chemotherapy.
Non-sterilized male participants must be willing to use a medically accepted contraceptive measure (such as intrauterine device, oral contraceptives, or condoms) during the study treatment period, for at least 3 months after the last dose of toripalimab, and for at least 6 months after the last dose of chemotherapy.

You may not qualify if…

History of allergic reactions to any components of toripalimab, paclitaxel, or cisplatin.
Pre-existing tracheostomy due to laryngeal dysfunction before treatment.
History of or concurrent presence of other malignancies (except for those cured and with no cancer-related survival exceeding 5 years, such as basal cell carcinoma of the skin, cervical carcinoma in situ, and papillary thyroid cancer). Patients with concurrent hypopharyngeal and esophageal cancers, where the lesions are not anatomically adjacent, will be diagnosed as having dual primary tumors and will not be eligible for inclusion.
Uncontrolled clinical cardiac symptoms or diseases, including:
NYHA Class II or higher heart failure.
Unstable angina.
Myocardial infarction within the past year.
Clinically significant ventricular or supraventricular arrhythmias requiring clinical intervention.
Previous treatment with any of the following:
Use of any investigational drug within 4 weeks prior to the first dose of study treatment.
Concurrent participation in another clinical trial, unless it is an observational (non-interventional) clinical trial.
Requiring systemic treatment with corticosteroids (daily dose >10 mg prednisone equivalent) or other immunosuppressive medications within 2 weeks prior to the first dose of study treatment, excluding corticosteroids for localized inflammation or prophylaxis against allergies or nausea/vomiting. Other specific circumstances should be discussed with the investigator. In the absence of active autoimmune disease, inhaled or topical steroids and adrenal replacement therapy with a dose of >10 mg/day prednisone or equivalent are allowed.
Vaccination with anti-tumor vaccines or administration of live vaccines within 4 weeks prior to the first dose of study treatment (for patients who received COVID-19 vaccine, a 2-week interval is required).

Baseline chest imaging indicating active pulmonary inflammation, presence of symptoms and signs of infection within 4 weeks before the first dose of study treatment, or requirement for oral or intravenous antibiotics to treat infection are exclusion criteria.
