Lead Sponsor:
National Cancer Institute (NCI)
Conditions:
Oropharyngeal Squamous Cell Carcinoma (SCC)
Eligibility:
All Genders
18-120 years
Phase:
PHASE2
Brief Summary
Background: Cancers in and around the mouth associated with human papilloma virus (HPV) are common. Two treatments (the drug pembrolizumab and the HPV vaccine PRGN-2009) have been shown to work well ...

Background -Human papilloma virus-associated oropharyngeal cancer (HPV-OPC) is the most common HPV-associated malignancy in the United States, with an increasing incidence. Although the prognosis for...
Eligibility Criteria
Inclusion
- INCLUSION CRITERIA:
- Subjects must have cytologically or histologically confirmed newly diagnosed stage I (T1,2 N1), II or III p16-positive oropharyngeal squamous cell carcinoma (SCC) planned for definitive therapy (surgery or chemoradiotherapy).
- Subjects must have measurable disease, per RECIST 1.1.
- Age \>=18 years.
- Eastern Cooperative Oncology Group \[ECOG\] performance status \<= 2.
- Adequate hematologic function at screening, as follows:
- Absolute neutrophil count (ANC) \>=1 x 10\^9/L;
- Hemoglobin (Hgb) \>= 9 g/dL;
- Platelets \>= 75,000/microliter.
- Adequate renal and hepatic function at screening, as follows:
- Serum creatinine \<= 1.5 x upper limit of normal (ULN) OR measured or calculated creatinine clearance \>= 40 mL/min for participant with creatinine levels \> 1.5 x ULN (glomerular filtration rate \[GFR\] can also be used in place of creatinine or CrCl);
- Total bilirubin \<= 1.5 x ULN OR in subjects with Gilbert s syndrome, a total bilirubin \<= 3.0 x ULN;
- Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) \<= 2.5 x ULN, unless liver metastases are present, then values must be \<= 3 x ULN.
- Participants serologically positive for HIV, Hepatitis B, or Hepatitis C are eligible if the viral loads are undetectable by quantitative PCR. Note: HIV positive participants must have CD4 count \>= 200 cells/mm\^3 at enrollment, be on stable antiretroviral therapy for at least 4 weeks and have no reported opportunistic infections or Castleman s disease within 12 months prior to enrollment.
- Women of child-bearing potential (WOCBP) must agree to use effective contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation and for at least 4 months following the last dose of pembrolizumab.
- Participants must be willing to undergo two research biopsies on this study.
- Ability of participant to understand and the willingness to sign a written informed consent document.
- EXCLUSION CRITERIA:
- Participants with prior investigational drug, live vaccine, chemotherapy, immunotherapy, or any prior radiotherapy (except for palliative bone directed therapy) within the past 4 weeks prior to the first drug administration. Participants may continue adjuvant hormonal therapy in the setting of a definitively treated cancer (e.g., breast).
- Major surgery within 28 days prior to the first drug administration (minimally invasive procedures such as diagnostic biopsies are permitted).
- Pregnant individuals as evaluated by a positive serum or urine Beta-hCG at screening
- Active autoimmune disease that might deteriorate when receiving an immunostimulatory agent with the exception of:
- Diabetes type I, eczema, vitiligo, alopecia, psoriasis, hypo- or hyperthyroidism or other mild autoimmune disorders not requiring immunosuppressive treatment.
- Administration of glucocorticoids through a route known to result in a minimal systemic exposure (topical, intranasal, intraocular, or inhalation).
- Systemic (intravenous or oral) glucocorticoid (except for physiologic doses of corticosteroids, i.e., \<= the equivalent of prednisone 10 mg/day) or other immunosuppressors such as azathioprine or cyclosporin A, are excluded because of potential immune suppression. These treatments must be discontinued at least 1 week prior to enrollment for recent short course use (\<= 14 days). Glucocorticoids as premedication for contrast-enhanced studies is allowed prior to enrollment and on study.
- Participants with a prior or concurrent malignancy whose natural history or treatment that has potential to interfere with the safety or efficacy assessment of the regimen.
- Prior allogenic tissue/solid organ transplant.
- Participants with pulse oximetry \< 92% on room air at screening.
- Uncontrolled intercurrent illness that would limit compliance with study requirements suggested by medical history, physical examination or standard clinical assessments such as imaging and laboratory studies.
