NCT05578170

Brief Summary

The purpose of this prospective, single-center, single-arm, open-label II phase observation clinical trial is to evaluate the efficacy and safety of Pembrolizumab immunoadjuvant therapy in patients with stage III-IVA oral squamous cell carcinoma. The primary end point is the pathological tumor remission rate of the primary tumor and regional lymph nodes after neoadjuvant immunotherapy (pTR-2: the proportion of necrotic tumor cells, keratin fragments and giant cells in tissue sections \> 50%). The secondary endpoints are 1-year disease-free survival (DFS), 1-year overall survival (OS) and the incidence of adverse events, compared with historical data. In addition, we will check the relevant immune indicators, such as PD-L1 and CPS scores.

Outcome Measures

Primary Outcomes (1)

  • Rate of pathologic tumor response-2(pTR-2)

    The proportion of participants with a pathologic tumor response-2(pTR-2)as assessed by the Central Pathologist at the time of definitive surgery. pTR-2 is defined as the proportion of necrotic tumor cells, keratin fragments and giant cells in tissue sections \> 50%

    Up to 30 days post-sugery

Secondary Outcomes (3)

  • Disease-free Survival (DFS)

    Up to 1 year

  • Overall Survival (OS)

    Up to 1 year

  • Adverse Events (AEs)

    From time of first dose of study treatment until the end of follow-up (up to 1 year)

Study Arms (1)

Pembro Neoadjuvant + SOC Adjuvant

Drug: Pembrolizumab

Interventions

Participants receive 200 mg pembrolizumab as a neoadjuvant by intravenous (IV) infusion administered on Day 1 of a 21-day cycle for 2 cycles before surgery.

Study Population

Patients with stage III-IVA oral squamous cell carcinoma.(See Eligibility Criteria)

You may qualify if:

  • Age 18-70
  • Male and female
  • Patients histologically or cytologically difined as oral cavity squamous cell carcinoma
  • According to the American Joint Committee on Cancer ( AJCC 8th Edition ) , patients with resectable stage III-IVA OCSCC
  • ECOG performance status ≤ 1
  • Patients with normal bone marrow and organ function as defined below:
  • Blood routine examination:
  • Absolute neutrophil count ≥ 1.5×109/L;
  • Platelets ≥ 100.0×109/L;
  • Hemoglobin ≥ 9.0 g/dL.
  • Liver function:
  • Totle bilirubin ≤ 2.0×ULN(Upper Limit Of Normal);
  • Alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase
  • ×ULN;
  • Albumin ≥ 2.8g/dL.
  • +6 more criteria

You may not qualify if:

  • Prior treatment for OCSCC (sugery, immunotherapy, radiotherapy, chemotherapy)
  • Patients with metastatic OCSCC with an unknown primary tumor site
  • Patients with infectious disease: AIDS, hepatitis, active tuberculosis
  • Received a live vaccine within 30 days prior to the first dose of pembrolizumab. Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, varicella/zoster, yellow fever, rabies, Bacillus Calmette-Guérin ( BCG ), typhoid vaccine, or attenuated flu vaccine
  • Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior to the first dose of pembrolizumab
  • Currently receiving any other investigational agents
  • Has a history of allergic reactions attributed to compounds of similar chemical of biologic composition to pembrolizumab or other agents used in the study
  • Patients with ongoing or active infectoin requiring systemic therapy, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, underlying pulmonary disease, or psychiatric illness/social situations that would limit compliance with study requirements
  • Has a or more active autoimmune disease
  • Has a history( non-infectious ) pneumonitis that required steroids or current pneumonitis
