Nab-Paclitaxel in Combination With Nivolumab to Treat Recurrent or Metastatic Head and Neck Squamous-Cell Carcinoma That Progressed on a PD-1 or PD-L1 Inhibitor

Prior treatment

• Has known active CNS metastases. Subjects with previously treated brain metastases may participate provided they are stable (without any evidence of progression by imaging 4 weeks prior to the first dose of study treatment and any neurologic symptoms have stabilized), have no evidence of new or enlarging brain metastases, and are on stable or tapering doses of steroids for at least 14 days prior to first dose of study treatment.
• Receiving systemic corticosteroid therapy (in doses exceeding 10 mg daily of prednisone equivalent) within 7 days prior to the first dose of treatment. A history of severe autoimmune disorder requiring high-dose corticosteroid treatment due to prior PD-1 inhibitor is an exclusion criterion.
• Prior organ or allogeneic stem cell transplant.
• Prior taxane (including paclitaxel or docetaxel) given to treat recurrent or metastatic disease.
• Prior taxane (including paclitaxel or docetaxel) given as a component of a curatively intended multimodality therapy IF the latter was completed within 6 months of subsequent development of recurrent or metastatic disease.

Other illness

• A history of other malignancy with the exception of malignancies for which all treatment was completed at least 1 year before registration and the patient has no evidence of disease.
• A history of serious allergic reactions attributed to compounds of similar chemical or biologic composition to agents used in the study (Allergic reaction to cetuximab is allowed as there are other standard of care options for the investigator's choice arm).
• Uncontrolled serious intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, or cardiac arrhythmia.
• Has an active autoimmune disease (i.e. rheumatoid arthritis, lupus, Sjogren's syndrome) that has required IV or subcutaneous systemic treatment in the past 6 months (excluding Rituxan). Replacement therapy (i.e. thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.

Lab values

• Pregnant and/or breastfeeding. Women of childbearing potential must have a negative serum pregnancy test within 24 hours prior to the start of study treatment.

Other

• Greater than Grade 2 pre-existing peripheral neuropathy (per CTCAE).
• Prisoners, or subjects who are compulsory detained.

• Histologically or cytologically confirmed recurrent or metastatic HNSCC of the oral cavity, larynx, hypopharynx, oropharynx, or p16 positive neck node with unknown primary (but clinically thought to be oropharynx).
• Known p16 status (positive or negative) if oropharynx or unknown primary of the neck.
• Measurable disease per RECIST. Measurable disease defined as lesions that can be accurately measured in at least one dimension (longest diameter to be recorded) as ≥ 10 mm with CT scan, as ≥ 20 mm by chest x-ray, or ≥ 10 mm with calipers by clinical exam.
• Progression of disease, as assessed by RECIST, that occurred on a PD-1 or PD-L1 inhibitor (given alone or with other therapy) to treat recurrent or metastatic disease. Progression of disease that occurred on a PD-1 or PD-L1 inhibitor given as a component of a curative-intent regimen is excluded.
• PD-L1 CPS by IHC (22C3 antibody) on tumor tissue is strongly encouraged to be available or performed, although the test result is not required to enroll onto the trial. Patients with tumor PD-L1 TPS (but not CPS) available are also eligible; but, PD-L1 CPS should be performed in these cases. Fresh tumor tissue (obtained after progression on prior PD-1 or PD-L1 inhibitor given for recurrent or metastatic disease) is strongly preferred, but archived tumor tissue from recurrence or initial diagnosis is also acceptable.
• At least 18 years of age.
• ECOG performance status \< 1
• Normal bone marrow and organ function as defined below:
  • Hemoglobin \> 9 g/L
  • Absolute neutrophil count ≥ 1,500/mcl
  • Platelets ≥ 100,000/mcl (transfusion independent, defined as not receiving platelet transfusions within 7 days prior to laboratory sample)
  • Total bilirubin ≤ 1.5 mg/dL
  • AST(SGOT)/ALT(SGPT) ≤ 2.5 x IULN (in cases of bone mets or liver mets, AST/ALT \< 5 x IULN)
  • Serum creatinine \<1.5 x IULN or creatinine clearance \> 50 mL/min by Cockcroft-Gault
• The effects of nivolumab and nab-paclitaxel on the developing human fetus are unknown. For this reason and because monoclonal antibodies and antimicrotubule agents are known to be teratogenic, women of childbearing potential (WOCBP) and men must agree to use adequate contraception (hormonal or barrier method of birth control, abstinence) prior to study entry, for the duration of study participation, and for 6 months after the last dose of study treatment. Should a woman become pregnant or suspect she is pregnant while participating in this study, she must inform her treating physician immediately.
• Ability to understand and willingness to sign an IRB approved written informed consent document (or that of legally authorized representative, if applicable) before the performance of any protocol-related procedures.
