Study of Nivolumab Alone or in Combination With Ipilimumab as Immunotherapy vs Standard Follow-up in Surgical Resectable HNSCC After Adjuvant Therapy (IMSTAR-HN)

This is an interventional treatment trial for Head and Neck Cancer Read More

Inclusion Criteria:

• Histologically proven SCC of the oropharynx, oral cavity, hypopharynx, and larynx (not older than 3 months before randomization)
• clinical stage III-IVB (T1, N2-3; T2, N2-3; T3, N0-3; T4a, N0-3)
• Oropharyngeal cancer HPV-negative (p16 immunohistochemistry negative)
• Primary tumor and neck metastasis must be resectable
• Written and signed informed consent
• Performance Status of 0 or 1 using ECOG
• Male and female with age ≥ 18
• Curative treatment intent (cM0)

• Screening laboratory values must meet the following criteria and should be obtained within 4 weeks prior to randomization

  • WBC ≥ 2000/μL
  • Neutrophils ≥ 1500/μL
  • Platelets ≥ 100 x103/μL
  • Hemoglobin > 9.0 g/dL
  • Serum creatinine ≤ 1.5 x ULN or creatinine clearance (CrCl) ≥ 40 mL/min (if using the Cockcroft-Gault formula below):
  • Female CrCl = (140 - age in years) x weight in kg x 0.85 72 x serum creatinine in mg/dL
  • Male CrCl = (140 - age in years) x weight in kg x 1.00 72 x serum creatinine in mg/dL
  • AST/ALT ≤ 3 x ULN
  • Total Bilirubin ≤ 1.5 x ULN (except subjects with Gilbert Syndrome, who can have total bilirubin < 3.0 mg/dL)
• Women of childbearing potential (WOCBP)1 must use appropriate method(s) of contraception. WOCBP should use an adequate method to avoid pregnancy for 23 weeks (30 days plus the time required for nivolumab to undergo five half-lives) after the last dose of investigational drug
• WOCBP must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within 24 hours prior to the start of nivolumab.
• Women must not be breastfeeding
• Men who are sexually active with WOCBP must use any contraceptive method with a failure rate of less than 1% per year. Men receiving nivolumab and who are sexually active with WOCBP will be instructed to adhere to contraception for a period of 31 weeks after the last dose of investigational product.

Exclusion Criteria:

• Patients should be excluded if they have an active, known or suspected autoimmune disease. Subjects are permitted to enroll if they have vitiligo, type I diabetes mellitus, residual hypothyroidism due to autoimmune condition only requiring hormone replacement, psoriasis not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger
• Patients should be excluded if they have a condition requiring systemic treatment with either corticosteroids (> 10 mg daily prednisone equivalents) or other immunosuppressive medications within 14 days of study drug administration. Inhaled or topical steroids and adrenal replacement doses > 10 mg daily prednisone equivalents are permitted in the absence of active autoimmune disease.
• As there is potential for hepatic toxicity with nivolumab or nivolumab/ipilimumab combinations, drugs with a predisposition to hepatoxicity should be used with caution in patients treated with nivolumab-containing regimen.
• Patients should be excluded if they have had prior treatment with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CTLA-4 antibody, or any other antibody or drug specifically targeting T-cell costimulation or immune checkpoint pathways
• Prior invasive malignancy except controlled skin cancer or carcinoma in situ of cervix
• Unknown primary (CUP), nasopharyngeal or salivary gland cancer
• Distant metastatic disease or adenopathy below the clavicles
• Serious co-morbidity, e.g. high-grade carotid artery stenosis, congestive heart failure NYHA grade 3 and 4, liver cirrhosis CHILD C. If clinically suspected, further diagnostic is indicated according to the judgement of the investigator.
• Pregnancy or lactation
• Women of child-bearing potential with unclear contraception
• Previous treatment for the study cancer with chemotherapy, radiotherapy, EGFR-targeting agents or surgery exceeding biopsy in head and neck
• Prior radiotherapy to the region of the study cancer that would result in overlap of radiation therapy fields
• Concurrent treatment with other experimental drugs or participation in another clinical trial with any investigational drug within 30 days prior to study screening
• Patients should be excluded if they are positive test for hepatitis B virus surface antigen (HBV sAg) or hepatitis C virus ribonucleic acid (HCV antibody) indicating acute or chronic infection
• Patients should be excluded if they have known history of testing positive for human immunodeficiency virus (HIV) or known acquired immunodeficiency syndrome (AIDS)
• Allergies and Adverse Drug Reaction: History of severe hypersensitivity reaction to any monoclonal antibody
• History of allergy to study drug components
• Social situations that limit compliance with study requirements or patients with an unstable condition (e.g., psychiatric disorder, a recent history of drug or alcohol abuse, interfering with study compliance, within 6 months prior to screening) or otherwise thought to be unreliable or incapable of complying with the requirements of the protocol
• Patients institutionalized by official means or court order
• Deficient dental preservation status or not accomplished wound healing
