  • Ability to provide informed consent and documentation of informed consent prior to initiation of any study-related tests or procedures that are not part of standard of care for the Participant's disease. Participants must also be willing and able to comply with study procedures, including the acquisition of specified research specimens.
  • Age >18 years old
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
  • Life expectancy > 12 weeks
  • Measurable disease as per RECIST 1.1 and documented by computed tomography (CT) and/or magnetic resonance imaging (MRI). Cutaneous or subcutaneous lesions must be measurable by calipers. Note: Lesions to be used as measurable disease for the purpose of response assessment must either a) not reside in a field that has been subjected to prior radiotherapy, or b) have demonstrated clear evidence of radiographic progression since the completion of prior radiotherapy and prior to study enrollment.
  • Recurrent and metastatic HNSCC that has progressed following at least 1 prior systemic therapy. Participants must have received platinum-based chemotherapy and been offered checkpoint immunotherapy. The requirement for prior systemic therapy may be waived if a Participant was intolerant of or refused standard first or second-line therapies.
  • Participant must have HLA-A*0201 genotype as determined by genomic testing. Eligibility will be determined based on either local or central laboratory testing. If local results are used, then a duplicate sample must be submitted for confirmation at a central laboratory designated by the Sponsor.
  • Participant must have histologically and/or cytologically proven tumor(s) that are HPV16 positive and express p6INK4A. Archival tissue or formalin-fixed, paraffin-embedded (FFPE) tissue from a biopsy and / or surgery must be available for HPV16 and p16INK4A testing on all Participants enrolled. All tumors must test positive for HPV16 using ISH analysis and p16INK4A expression in tumor cells using IHC analysis. Eligibility will be based on either local or central HPV16 and p16INK4A testing. If local results are used then tissue must be submitted for confirmation in a central laboratory designated by the Sponsor.
  • All tumors must have histologically or cytologically confirmed diagnoses. Laboratory Features
  • Acceptable laboratory parameters as per protocol
  • Reproductive Features
  • Female Participants of childbearing potential (not surgically sterilized and between menarche and 1 year post-menopause) must have a negative serum pregnancy test performed within 72 hours prior to the initiation of study drug administration. Further, female Participants of childbearing potential must agree to use acceptable contraceptive measures from the time of consent through 120 days after discontinuation of study drug administration. For female Participants, 2 forms of contraception must be utilized and may include oral, transdermal, injectable or implantable contraceptives, intrauterine device, female condom, diaphragm with spermicide, cervical cap, use of a condom by the sexual partner or a sterile or vasectomized sexual partner. Periodic abstinence (eg, calendar, ovulation, symptothermal, and post ovulation methods) and withdrawal are not considered acceptable forms of contraception in this study.
  • Non-vasectomized male Participants with partners of childbearing potential must use barrier contraception. In addition, male Participants should also have their partners use another method of contraception from the time of consent through 30 days after discontinuation of study drug administration
  • Female Participants should not be pregnant or plan to become pregnant during the course of the trial.
  • Female Participants must not be breastfeeding.
  • Additional criteria apply

• Exclusion Criteria

  • Participants with symptomatic central nervous system (CNS) metastases must have been treated and be asymptomatic
  • Need for concurrent treatment for the CNS disease (eg, surgery, radiation, corticosteroids > 10 mg prednisone / day or equivalent)
  • Progression of CNS metastases on MRI or CT for at least 28 days after last day of prior therapy for the CNS metastases; and/or Concurrent leptomeningeal disease or cord compression.
  • Participants with any history of known or suspected autoimmune disease with the specific exceptions of the following: Vitiligo, Resolved childhood atopic dermatitis, Psoriasis (with exception of psoriatic arthritis) not requiring systemic treatment (within the past 2 years), Participants with a history of Grave's disease that are now euthyroid clinically and by laboratory testing
  • History of prior allogeneic tissue/solid organ transplantation.
  • Treatment with any systemic anti-neoplastic therapy, or investigational therapy within the 2 weeks prior to the initiation of study drug administration. Participants may be on an investigational or other anti-neoplastic therapy during the screening phase of the study.
  • Treatment with radiation therapy within 2 weeks prior to the initiation of study drug administration.
  • Treatment with corticosteroids (>10 mg per day prednisone or equivalent) or other immune suppressive drugs within the 14 days prior to the initiation of study drug administration. Steroids for topical, ophthalmic, inhaled, or nasal administration are allowed. Physiological replacement with hydrocortisone up to a maximum dose of 40 mg per day is allowed.
  • History of clinically significant cardiovascular disease including, but not limited to:
