Eligibility

Who can join

The film gives the main points. The full list below is copied from the registry; the study team makes the final decision.

  • Age18 Years to no maximum
  • SexAll
  • Healthy volunteersNo

You may be able to join if

  • Participants must have histologically or cytologically confirmed locoregionally recurrent squamous cell carcinoma of the head and neck, or second primary HNSCC in a previously irradiated field, defined as >50% of the presurgical tumor volume having prior radiation dose of >45 Gy as determined by the treating radiation oncologist (including primary sites, such as oral cavity, oropharynx, larynx or hypopharynx carcinoma).
  • Participants must be a candidate for curative intent surgery.
  • Participants must have documented time of ≥ 6 months from completion of prior curative intent treatment for HNSCC (surgery and/or radiation therapy with/without platinum chemotherapy or cetuximab targeted therapy) to diagnosis of local or locoregional recurrence or a second primary in a previously irradiated field.
  • Participants must be willing to undergo a mandatory pre-treatment biopsy and willing to provide blood and tissue from the pre-treatment biopsy and at the time of surgery. Exceptions may be made after discussion with sponsor if it is not medically feasible to obtain a pre-treatment biopsy or is in the best interest of the patient. Archival tissue may be collected in this situation. Participants will be offered the opportunity to volunteer for optional biopsies at the time of recurrence of disease.
  • Participants may have any smoking history (no restrictions)
  • Participants may have any Human Papilloma Virus (HPV) status of the tumor. Patients with oropharyngeal cancer are required to undergo HPV testing with p16 immunohistochemistry and/or confirmatory HPV PCR or ISH testing
  • Age ≥18 years
  • ECOG performance status 0 or 1 (Karnofsky ≥70%, see Appendix A)
  • Participants must have adequate organ and marrow function as defined below:
  • leukocytes ≥3,000/mcL
  • absolute neutrophil count ≥1,500/mcL
  • platelets ≥100,000/mcL
  • total bilirubin ≤ institutional upper limit of normal (ULN)
  • AST(SGOT)/ALT(SGPT) ≤3 × institutional ULN
  • creatinine ≤ institutional ULN OR
  • glomerular filtration rate (GFR) ≥50 mL/min/1.73 m2 unless data exists supporting safe use at lower kidney function values, no lower than 30 mL/min/1.73 m2.
  • Participants with known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, should have a clinical risk assessment of cardiac function using the New York Heart Association Functional Classification. To be eligible for this trial, participants should be class 2B or better.
  • Because pembrolizumab and chemotherapy can be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately.
  • Male participants: A male participant must agree to use a contraception as detailed in Appendix B of this protocol during the treatment period and for at least 180 days after the last dose of study treatment and refrain from donating sperm during this period.
  • Female participants: A female participant is eligible to participate if she is not pregnant (see Appendix B), not breastfeeding, and at least one of the following conditions applies:
  • a. Not a woman of childbearing potential (WOCBP) as defined in Appendix B OR
  • b. A WOCBP who agrees to follow the contraceptive guidance in Appendix B during the treatment period and for at least 180 days after the last dose of study treatment.
  • Ability to understand and the willingness to sign a written informed consent document.

You cannot join if

  • Sinonasal, nasopharyngeal or cutaneous primary site of squamous cell carcinoma of the head and neck
  • Has known distant metastatic disease. Those with known brain metastases should be excluded from this clinical trial, because of the poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events. However, baseline brain imaging is not required prior to enrollment in the study if patients are asymptomatic
  • Has had chemotherapy or radiotherapy for HNSCC in curative intent setting within 6 months prior to entering the study.
  • Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti PD L2 agent or with an agent directed to another stimulatory or co-inhibitory T-cell receptor (eg, CTLA-4, OX 40, CD137).
  • Has received a live vaccine or live-attenuated vaccine within 30 days prior to the first dose of study drug. Administration of killed vaccines is allowed
  • Is currently participating in or has participated in a study of an investigational agent or has used an investigational device within 4 weeks prior to the first dose of study intervention.
  • Has a diagnosis of immunodeficiency or is receiving chronic 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 study drug
  • Has a known additional malignancy that is progressing or has required active treatment within the past 2 years. Participants with basal cell carcinoma of the skin, squamous cell carcinoma of the skin or carcinoma in situ (eg, breast carcinoma, cervical cancer in situ) that have undergone potentially curative therapy are not excluded
  • Has a history of allergic reactions to agents used in study
  • Has active autoimmune disease that has required systemic treatment in past 2 years (ie, with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (eg, thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency) is not considered a form of systemic treatment and is allowed
  • Has a history of (non-infectious) pneumonitis/interstitial lung disease that required steroids or has current pneumonitis/interstitial lung disease
  • Has an active infection requiring systemic therapy
  • Has a known history of human immunodeficiency virus (HIV) infection. No HIV testing is required unless mandated by local health authority
  • Has a known history of Hepatitis B (defined as Hepatitis B surface antigen [HBsAg] reactive) or known active Hepatitis C virus (defined as HCV RNA [qualitative] is detected) infection. Note: no testing for Hepatitis B and Hepatitis C is required unless mandated by local health authority.
  • Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the participant's participation for the full duration of the study, or is not in the best interest of the participant to participate, in the opinion of the treating investigator.
  • Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial
  • Has not recovered from adverse events due to prior anti-cancer therapy (i.e., have residual toxicities > Grade 2) with the exception of alopecia
  • Has had an allogeneic tissue/solid organ transplant
  • A WOCBP who has a positive urine pregnancy test within 72 hours prior to study registration (see Appendix B). If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required. Pregnant women are excluded from this study because pembrolizumab and chemotherapy agents have the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with pembrolizumab and chemotherapy, breastfeeding should be discontinued if the mother is treated on this protocol.

The treatment

How it is intended to work

This is how the treatment is meant to work. Whether it helps, and how safe it is, is what this trial is testing.

pembrolizumab. A humanized monoclonal immunoglobulin (Ig) G4 antibody directed against human cell surface receptor PD-1 (programmed death-1 or programmed cell death-1) with potential immune checkpoint inhibitory and antineoplastic activities. Upon administration, pembrolizumab binds to PD-1, an inhibitory signaling receptor expressed on the surface of activated T cells, and blocks the binding to and activation of PD-1 by its ligands, which results in the activation of T-cell-mediated immune responses against tumor cells. The ligands for PD-1 include programmed cell death ligand 1 (PD-L1), overexpressed on certain cancer cells, and programmed cell death ligand 2 (PD-L2), which is primarily expressed on APCs. Activated PD-1 negatively regulates T-cell activation and plays a key role in in tumor evasion from host immunity. NCI Drug Dictionary
