RECRUITING

NCT06151743

PHASE2

Neoadjuvant PD-1 Inhibitor Combined With Cetuximab and Platinum in Resectable Locally Advanced Hypopharyngeal Carcinoma

Sponsor: Eye & ENT Hospital of Fudan University

View on ClinicalTrials.gov

Summary

The purpose of this clinical trial is to evaluate the efficacy and safety of immunotherapy combined with cetuximab and platinum neoadjuvant therapy in patients with resectable locally advanced hypopharyngeal cancer. Participants will receive three cycles of TPC neoadjuvant therapy (toripalimab+ cetuximab + platinum), radical surgery (laryngeal preservation surgery if possible), and sequential (chemo)radiotherapy treatment after surgery. This trial aims to answer the following questions: 1. pCR rate 2. MPR rate, ORR, LPR/DFS/OS rare at 1 and 2 years 3. Safety and quality of life

Interventions

DRUG

three cycles (toripalimab + cetuximab + platinum)

Cetuximab 250 mg/m2 i.v. qw (first loading dose 400 mg/m2) for nine doses; Toripalimab 240 mg/m2 i.v. d1, q21d, three cycles; Cisplatin 25 mg/m2 i.v. d1-3, q21d, three cycles or Carboplatin AUC 5 i.v. d1, q21d, three cycles (patients with cisplatin contraindications or renal impairment after cisplatin use).

PROCEDURE

Radical surgery

The attending physician should select the appropriate surgical treatment and try to perform radical laryngeal preservation surgery for patients with tumor retraction after induction therapy. Patients who cannot preserve laryngeal function due to tumor load need to undergo total laryngeal resection. According to the scope of pharyngectomy, the surgical treatments include partial laryngopharyngectomy, total laryngectomy and partial pharyngectomy, total laryngopharyngectomy, and total pharyngo-laryngo-esophagectomy. Cervical lymph node dissection was performed when necessary.

RADIATION

Radiotherapy or chemoradiotherapy

1. Using intensity-modulated radiotherapy (IMRT) technology, the dose of radiotherapy is determined according to whether there are adverse prognostic factors in the postoperative pathology, including positive margins, extracapsular invasion of lymph nodes, primary pT3 or T4, N2 lymph node lesions, peripheral nerve invasion, vascular/lymphatic infiltration. Primary site: residual GTV or tumor bed dose 60-70Gy: 1.8-2.12 Gy / fraction. Cervical lymph nodes or lymphatic drainage area: 56-70 Gy: 1.7-2.12 Gy / fraction. 2. Postoperative adjuvant concurrent chemotherapy regimen: Cisplatin 25mg/m2 i.v. d1-3, d22-24 or Carboplatin AUC 5 i.v. d1, d22 (if cisplatin contraindications).

Inclusion Criteria: * Pathologically confirmed as hypopharyngeal squamous cell carcinoma; * Age between 18-75 years; * Patients with resectable locally advanced hypopharyngeal cancer with T3-4aN0-3bM0 (AJCC 8th) require total laryngectomy; * Have at least one evaluable target lesion according to RECIST 1.1 criteria. * No previous treatment for hypopharyngeal carcinoma; * Satisfactory performance status: ECOG (Eastern Cooperative Oncology Group) scale 0-1; * Estimated survival ≥ 6 months; * Normal organ function; * HBV DNA \< 500 IU/mL (or 2500 copies/mL) and HCV RNA negative; * Signed informed consent; * Patients who are compliant, willing, and able to follow visiting schedules, treatment plans, laboratory tests, and other research procedures. * Male and no pregnant female; able to use the contraceptive method during treatment. Exclusion Criteria: * Have a history of other cancers in the past five years, except for the following cancers that are cured in the past five years: basal cell carcinoma and squamous cell carcinoma of the skin, early prostate cancer, papillary thyroid cancer, breast ductal carcinoma in situ and cervix carcinoma in situ; * The target lesion has been treated with radiation therapy or surgery, except for biopsy to confirm the diagnosis of hypopharyngeal carcinoma; * Previous chemotherapy, immunotherapy, or bio-targeted therapy for the primary tumor; * Patients who have participated in other clinical trials within four weeks before the trial; * Any of the following diseases within six months: myocardial infarction, severe/unstable angina, coronary/peripheral artery bypass grafting, symptomatic congestive heart failure, cerebrovascular accident, transient ischemic attack, or symptomatic pulmonary embolism. * Those with hypertension who cannot be reduced to normal range by antihypertensive drugs (systolic blood pressure \> 140 mmHg, diastolic blood pressure \> 90 mmHg). * Patients with grade I or above coronary heart disease, arrhythmia (including QTc interval prolongation \> 450 ms for men and \> 470 ms for women), and cardiac insufficiency. * Patients with positive urine protein (urine protein test 2 + or above, or 24-hour urine protein quantification \>1.0g). * Patients with severe allergic history or allergic constitution; an active autoimmune disease that may worsen when receiving immunostimulants. Patients with type I diabetes, vitiligo, psoriasis, or diseases of hypothyroidism or hyperthyroidism that do not require immunosuppressive therapy are eligible to participate in the study. * Subjects requiring systemic therapy with corticosteroids (\> 10 mg prednisone or equivalent) or other immunosuppressants within two weeks before the first use of the study drug. * Previously diagnosed immunodeficiency or known human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS) - related disease. hepatitis B virus (HBV) surface antigen positive and HBV-DNA ≥ 500 IU/mL (or 2500 copies/mL), or HCV RNA positive. History of active or previous tuberculosis (TB). * Patients with a history of psychotropic substance abuse who cannot quit or have mental disorders. * Vaccination within four weeks before enrollment, except for inactivated vaccine. * Pregnant or lactating women, those who are in the reproductive period and do not use effective contraception; * Those whom the investigator deems unsuitable to participate in this trial, such as severe acute or chronic medical conditions (including immune colitis, inflammatory bowel disease, non-infectious pneumonia, pulmonary fibrosis) or psychiatric illness (including recent or active suicidal ideation or behavior) or abnormal laboratory tests.
