Brief Summary

The purpose of this study is to compare the pharmacokinetic, safety, immunogenicity and efficacy of CMAB819 and Nivolumab in subjects with recurrent or metastatic head and neck squamous cell carcinoma., after failure of prior platinum-based chemotherapy.

Detailed Description

Patients were randomized to receive CMAB819 or Nivolumab 480 mg by intravenous infusion every 4 weeks until documented disease progression, discontinuation, withdrawal of consent, or up to 4 doses in subjects without disease progression, whichever occurs earlier. After completing 4 doses of therapy, administer of CMAB819 480 mg intravenous (IV) solution for injection every 4 weeks until documented disease progression, discontinuation, withdrawal of consent or the study ends. Randomization was stratified by Eastern Cooperative Oncology Group (ECOG) performance status ECOG (0 versus 1), sex (male versus female), weight （≤60 kg versus >60kg）and clinical trial institution (up to 20 centers) .

Eligibility Criteria

Inclusion Criteria

1. Males or females, Aged ≥18 years and ≤75 years.

2. Eastern Cooperative Oncology Group (ECOG) performance status of ≤1.

3. Life expectancy of at least 3 months.

4. Histologically or cytologically confirmed recurrent or metastatic SCCHN (oropharynx, oral cavity, hypopharynx, larynx, etc.), Stage III/IV and not amenable to local therapy with curative intent (surgery or radiation therapy with or without chemotherapy).

5. Tumor tissue (archival or fresh biopsy specimen wthin 3 years) must be available for PD-L1 expression analysis.

6. Subjects must have experienced disease recurrence or progression during or after last dose of platinum therapy for advanced or metastatic disease.

(i)Subjects who received adjuvant or neoadjuvant platinum-based chemotherapy (after surgery and/or radiation therapy) and developed recurrent or metastatic disease within 3~6 months of completing therapy are eligible. (ii)Subjects with recurrent disease > 6 months after adjuvant or neoadjuvant platinum-based chemotherapy, who also subsequently progressed during or after a platinum- doublet regimen given to treat the recurrence, are eligible.

7. Subjects must have measurable disease by CT or MRI per RECIST 1.1 criteria.

8. All toxicities attributed to prior anti-cancer therapy other than alopecia and fatigue must have resolved to Grade 1 (NCI CTCAE version 5.0) or baseline before administration of study drug. Subjects with toxicities attributed to prior anti-cancer therapy which are not expected to resolve and result in long lasting sequelae, such as neuropathy after platinum based therapy, are permitted to enroll.

9. Medically accepted effective contraception if procreative potential exists (applicable for both male and female subjects until at least 6 months after the last dose of trial treatment).

10. All baseline laboratory requirements will be assessed and should be obtained within -14 days of randomization. Screening laboratory values must meet the following criteria： (i) Blood routine: (a) Neutrophils ≥ 1.5 x 10^9/L；(b) Platelets ≥ 75 x 10^9/L；(c) Hemoglobin ≥ 90 g/L.

(ii) Liver function: (a) AST ≤ 1.5 x ULN (subjects with liver metastasis≤ 5 x ULN); (b) ALT ≤ 1.5 x ULN (subjects with liver metastasis≤ 5 x ULN); (c) Total bilirubin ≤ 1.5 ULN [except subjects with Gilbert Syndrome who must have total bilirubin < 2.5 x ULN（3.0 mg/dL)].

(iii) Renal function: (a) Serum creatinine of ≤ 1.5 x ULN or creatinine clearance ≥ 50 mL/minute (using Cockcroft/Gault formula).

11. Signed the informed consent form voluntarily.

Exclusion Criteria

1. Histologically or cytologically confirmed recurrent or metastatic nasopharyngeal darcinoma, squamous carcinoma of unknown primary, salivary gland carcinoma, or cutaneous squamous cell carcinoma.

2. Subjects with active CNS metastases and/or carcinomatous meningitis. Subjects are eligible if CNS metastases are adequately treated and subjects are neurologically returned to baseline (except for residual signs or symptoms related to the CNS treatment) for at least 2 weeks prior to enrollment. In addition, subjects must be either off corticosteroids, or on a stable or decreasing dose of ≤ 10 mg daily prednisone (or equivalent).

Subjects with vitiligo, type I diabetes mellitus, residual hypothyroidism due to autoimmune thyroiditis only requiring hormone replacement, or conditions not expected to recur in the absence of an external trigger are permitted to enroll.

5. Subjects with immunodeficiency inculding testing positive for human immunodeficiency virus (HIV) , acquired or congenital immunodeficiency disease, or organ transplantation.
