1. Men and women = 18 years of age.
2. Provide informed consent signed by study patient.
3. Willing and able to comply with site visits and study-related procedures and requirements.
4. Histologically confirmed recurrent or metastatic HPV16-positive Oropharyngeal Cancer (OPC)*. Patients with squamous cell carcinoma (SCC) of occult primary site, presenting with lymph node(s) limited only to the neck, are also eligible. Patients should have HPV16 positivity confirmed before being considered a candidate for this study, see inclusion criteria 5.
* Recurrent or metastatic disease in the context of this study if defined as recurrent, metastatic or advanced disease.
5. HPV16 genotyping as determined by a specified central reference laboratory with an established polymerase chain reaction (PCR)-based assay. If local specific HPV16 genotype assessment (PCR or in situ hybridization (ISH) has been performed, the patient can be enrolled if the result shows HPV16 positivity. Confirmation of HPV16 positive status will then subsequently have to be performed by the central laboratory.
6. Patients who have received a minimum total dose of 600 mg of pembrolizumab or 960 mg of nivolumab or equivalent anti-PD-1 antibody with or without chemotherapy for only 1st or 2nd line recurrent/metastatic HPV16 positive OPC. The last dose of anti-PD-1 must have been no more than 6 months prior to the first dose of study drug. Progressive disease (PD) must have been diagnosed during or after anti-PD-1 therapy (but not longer than 6 months after the last dose). Prior treatment regimens must have included platinum-based chemotherapy, 5-fluorouracil (5-FU) or an alternative fluoropyrimidine, and cetuximab, if appropriate. Anti-PD-1 therapy (as 1st or 2nd line for recurrent/ metastatic HPV16 positive OPC) should have been the last treatment regimen that the patient received before entry into the current trial.
7. Pre-screening consent only: ability to provide archived tumor sample (preferably tumor block or otherwise at least 10 unstained slides) to allow determination of HPV16- status by the central laboratory -or a local laboratory if applicable- using an investigational use only assay.
8. At least one measurable lesion by computed tomography (CT) or magnetic resonance imaging (MRI) per RECIST version 1.1 criteria. Target lesions may be located in a previously irradiated field if there is documented (radiographic) disease progression in that site.
9. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
10. Adequate organ and bone marrow function documented by:
a. Hemoglobin = 8 g/dL
b. Absolute neutrophil count = 1.5 x 109/L
c. Platelet count = 75 x 109/L
d. Serum creatinine = 1.5 x upper limit of normal (ULN) and estimated glomerular filtration rate > 30 mL/min/1.73m2. A 24-hour urine creatinine collection may substitute for the calculated creatinine clearance to meet eligibility criteria or creatinine clearance (CrCl) > 30 mL/min (using the Cockcroft-Gault formula): 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
e. Adequate hepatic function:
i. Total bilirubin = 1.5 x upper limit of normal (ULN) (=3 x ULN if tumor liver involvement)
ii. Aspartase Aminotransferase (AST) = 2.5 x ULN (=3 x ULN if tumor liver involvement)
iii. Alanine Aminotransferase (ALT) = 2.5 x ULN (=3 xULN if tumor liver involvement)
iv. Alkaline Phospha
1. Invasive surgery (defined as surgical intervention requiring general or
spinal anesthesia and hospital admission) within 4 weeks prior to start
of study treatment.
2. Patients who, after progressing on anti-PD-1, received additional anticancer
therapy (chemotherapy, radiotherapy, experimental TKIs,
immunotherapy, anti-EGFR antibodies, surgery). The following palliative
treatments are allowed:
- palliative radiotherapy (but NOT for target lesions)
- palliative surgery
- bone resorptive therapy such as bisphosphonates and denosumab but
only if patients have been on stable doses for > 4 weeks prior to first
dose of test treatment
3. Patients who have permanently discontinued anti-cancer immune
modulating therapies due to drug-related toxicity.
4. Another malignancy that is progressing or requires active treatment
and/or history of malignancy other than oropharyngeal cancer within 3
years of date of first planned dose of study drug, except:
a. Non-melanoma skin cancer that has undergone potentially curative
therapy
b. In situ cervical carcinoma
c. Ductal carcinoma in situ of the breast
d. In-situ prostate cancer with non-detectable prostate specific antigen
e. Any tumor that has been deemed to be effectively treated with
definitive local control (with or without continued adjuvant hormonal
therapy), and the patient is deemed to be in complete remission for at
least 2 years prior to randomization, and no additional therapy is
required during the study period.
5. Any condition that requires ongoing/continuous corticosteroid
therapy (> 10 mg prednisone/day or anti-inflammatory equivalent)
within 1 week prior to the first dose of study therapy. Patients who
require a brief course of steroids (up to 2 days in the week before
enrollment) or physiologic replacement are not excluded.
6. Ongoing or recent (within 5 years) evidence of significant
autoimmune disease that required treatment with systemic
immunosuppressive treatments. The following are not exclusionary:
vitiligo, childhood asthma that has resolved, endocrinopathies (such as
hypothyroidism or type 1 diabetes) that require only hormone
replacement, or psoriasis that does not require systemic treatment.
7. Subjects with known brain metastases or leptomeningeal metastases.
8. Encephalitis, meningitis, organic brain disease or uncontrolled
seizures in the year prior to first dose of study therapy.
9. Known history of, or any evidence of interstitial lung disease, or
active, non-infectious pneumonitis (in the past 5 years). A history of
radiation pneumonitis in the radiation field is permitted.
10. Has participated in a study of an investigational agent or an
investigational device, unless approved by the Sponsor
11. Prior treatment with therapeutic anti-HPV vaccines including ISA101
or ISA101b. Patients who have received a preventive HPV vaccine are
allowed
12. Grade 1 or greater toxicities attributed to systemic prior anti-cancer
therapy other than alopecia, fatigue (NCI CTCAE), radiation dermatitis,
laboratory abnormalities that are not considered clinically significant by
the treating physician, before administration of study
drug.
13. Uncontrolled infection with human immunodeficiency virus, hepatitis
B or hepatitis C infection; or diagnosis of immunodeficiency.
14. Any infection requiring hospitalization or treatment with IV antiinfectives
within 2 weeks of first dose of study therapy.

drug.
