• Patients must not have received more than 2 prior line of systemic treatment (i.e. in the second or third line of treatment) in the recurrent/metastatic setting.
  • o Ambiguity regarding lines of treatment a patient has received will be subject to PI review and approval.
• Patients who have previously received topoisomerase I inhibitors for HNSCC
• Have had a prior anti-cancer biologic agent, chemotherapy, targeted small molecule therapy, or radiation therapy within 2 weeks prior to study Day 1.
• Have not recovered (ie, ≤ Grade 1) from AEs due to a previously administered agent.
  • Note: Subjects with ≤ Grade 2 neuropathy or ≤ Grade 2 alopecia are exceptions to this criterion and may qualify for the study.
  • Note: If subjects underwent major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting study drug.
  • Note: Subjects with Grade ≤ 2 immune-mediated toxicities (except colitis which must be recovered, < Grade 1) related to immunotherapy and/or radiation treatment that are long lasting, but stable on treatment and not requiring agents that are excluded by this protocol may qualify for the study.
• Have known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Subjects with previously treated brain metastases may participate provided they have stable CNS disease for at least 4 weeks prior to the first dose of study drug and all neurologic symptoms have returned to baseline, no evidence of new or enlarging brain metastases and are taking ≤ 20 mg/day of prednisone or its equivalent. All subjects with carcinomatous meningitis are excluded regardless of clinical stability.
• Herbal remedies known to potentially interfere with major organ function within 28 days prior to the first dose of study treatment, unless agreed otherwise between the PI and treating investigator.

• Severe, active co-morbidity defined as the following:
  • Unstable angina and/or congestive heart failure requiring hospitalization within the last 6 months
  • Transmural myocardial infarction within the last 6 months

• Known acquired immunodeficiency syndrome due to untreated/poorly controlled human immunodeficiency virus. Other diagnosed immunodeficiency syndromes or disorders will require the review and approval of the site PI.
• Positive test for hepatitis B surface antigen (HBsAG) or hepatitis C virus antibody (anti-HCV), indicating acute or chronic infection. Patients who test positive for anti-HCV but negative for HCV ribonucleic acid (RNA) are permitted to enroll.

Laborértékek

• Patients with previous severe infusion or allergic reactions to EGFR antibody based therapy that is deemed unsafe for re-challenge based on assessment by PI and/or consultation with allergy/immunology.

Egyéb

• Female patients who are pregnant, breastfeeding, or plan on becoming pregnant during the study.

• Pathologically (histologically or cytologically) proven diagnosis of squamous cell carcinoma of the head and neck arising from the sinuses, nasal cavity, oral cavity, oropharynx, hypopharynx, and larynx. Other sites not listed will be subject to PI discretion.
  • Advanced disease (Stage IV or M1 disease) not amenable to curative local therapy with surgery and/or radiation based approaches
  • Progression on first line anti-PD(L)1 therapy with or without chemotherapy or as part of a combination in a clinical trial
  • HPV status for oropharynx primary must be previously confirmed or can be performed on available archival or fresh biopsy via p16 immunohistochemistry or HPV specific testing via PCR or RNA ISH. Patients are able to enroll and initiate treatment so long as this is in progress. Exceptions may be made after discussion and review with P.I.
  • Have measurable disease per RECIST v1.1 criteria. Tumor lesions situated in previously radiated area may be utilized if they are measurable and progression has been demonstrated in these lesions.

  • Absolute neutrophil count (ANC) ≥ 1,500 cells/mm3
  • Platelets ≥ 100,000 cells/mm3
  • Hemoglobin ≥ 9.0 g/dl; Note: The use of transfusion or other intervention to achieve Hgb ≥ 9.0 g/dl is acceptable
• Adequate renal function within 30 days prior to registration, defined as follows:
  • o Serum creatinine < 2.0 x upper limit of normal (ULN) or creatinine clearance (CCr)
  • ≥ 30 ml/min determined by 24-hour collection or estimated by Cockcroft-Gault formula: CCr male = [(140 - age) x (wt in kg)] [(Serum Cr mg/dl) x (72)] CCr female = 0.85 x (CrCl male)
• Adequate hepatic function within 30 days prior to registration, defined as follows:
  • Total bilirubin ≤ 1.5 × ULN (except for unconjugated hyperbilirubinemia or Gilbert's syndrome). Direct bilirubin ≤ ULN for participants with total bilirubin levels > 1.5 × ULN.
  • AST and ALT < 2.5 x the upper limit of normal
  • Albumin ≥ 3 g/dL
