1. Men and women = 18 years of age.
2. Provide informed consent signed by study patient or legally acceptable representative.
3. Willing and able to comply with site visits and study-related procedures and requirements.
4. Histologically confirmed recurrent or metastatic HPV16-positive OPC. Patients with 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.
5. HPV16 genotyping as determined by a specified central reference laboratory with an established polymerase chain reaction (PCR)-based assay. If local HPV16 genotype assessment 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 of 4 doses of pembrolizumab or nivolumab or equivalent anti-PD-1 antibody with or without chemotherapy for 1st or 2nd line recurrent/metastatic HPV16-positive OPC. The last dose of anti-PD-1 must been no more than 6 months prior to enrollment into the trial. Progressive disease (PD) must have been diagnosed during or after anti-PD-1 therapy (but not longer than 6 months after the last dose).
7. Prescreening consent only: ability to provide archived tumor sample (tumor block or at least 10 unstained slides) to allow confirmation of HPV16-positive status by the central laboratory 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 = 1.0 x 109/L
c. Platelet count = 75 x 109/L
d. Serum creatinine = 1.5 x ULN or 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.
e. Adequate hepatic function:
i. Total bilirubin = 1.5 x upper limit of normal (ULN) (=3 x ULN if tumor liver involvement)
ii. Aspartate Aminotransferase (AST) = 2.5 x ULN (=3 x ULN if tumor liver involvement)
iii. Alanine Aminotransferase (ALT) = 2.5 x ULN (=3 x ULN if tumor liver involvement)
iv. Alkaline Phosphatase (ALP) = 2.5 x ULN (=3 x ULN if tumor liver or bone involvement)
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 43
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range 43
1. Major surgery within 14 days of first administration of enrollment.
2.Patients who, after progressing on anti-PD-1, required/ require additional anti-cancer therapy with curative intent subsequent chemotherapy within the last 4 weeks prior to enrollment in order to control disease. The following palliative treatments are allowed: palliative radiotherapy, palliative chemotherapy, 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, after progressing on anti-PD-1, required subsequent chemotherapy within the last 4 weeks prior to enrollment in order to control disease.
4. Patients who have permanently discontinued anti-cancer immune modulating therapies due to drug-related toxicity.
5. 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 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.
6. Any condition that requires ongoing/continuous corticosteroid therapy within 1 week prior to the first dose of study therapy. Patients who require a brief course of steroids or physiologic replacement are not excluded.
7. Ongoing or recent evidence of significant autoimmune disease that required treatment with systemic immunosuppressive treatments. The following are not exclusionary: vitiligo, childhood asthma that has resolved, endocrinopathies that require only hormone replacement, or psoriasis that does not require systemic treatment.
8. Untreated or active primary brain tumor, CNS metastases, leptomeningeal disease or spinal cord compression.
9. Encephalitis, meningitis, organic brain disease (e.g. Parkinson’s disease) or uncontrolled seizures in the year prior to first dose of study therapy.
10. Known history of, or any evidence of interstitial lung disease, or active, non-infectious pneumonitis. A history of radiation pneumonitis in the radiation field is permitted.
11. Has participated in a study of an investigational agent or an investigational device within 4 weeks of first dose of study therapy.
12. 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 anti infectives within 2 weeks of first dose of study therapy.
15. Receipt of a live vaccine within 4 weeks of planned start of study drug.
16. Prior allogeneic stem cell transplantation, or autologous stem cell transplantation within 12 weeks of the start of study drug, unless discussed with and approved by the Sponsor.
17. Recipients of organ transplants at any time unless discussed with and approved by the medical monitor.
18. Known allergy or hypersensitivity to components of study drug or excipients.
19. Known psychiatric or substance abuse disorders that would interfere with participation with the requirements of the study.
