Eligibility Criteria:
Inclusion Criteria:~* Be willing and able to provide written informed consent/assent for the trial.~* Be \>18 years of age on the day of signing the informed consent.~* Have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.~* Have histologically or cytologically confirmed advanced head and neck squamous cell cancer with cutaneous, subcutaneous or nodal tumors deemed as injectable lesions \[see definition below\] and have measurable disease for the primary study endpoint of overall response rate by RECIST 1.1 and iRECIST.In addition they must have (A) A single measurable tumor at least 1 cm in size and amenable to intratumoral injection or (B) Multiple measurable tumors that in aggregate have a longest diameter of ≥ 10 mm~Note: Injectable lesion definitions: lesions amenable to percutaneous approach, if technically feasible~* Recurrent and inoperable tumor, progressing after prior radiation with curative-intent for advanced disease (adjuvant or definitive with or without chemotherapy or cetuximab). No prior treatment for local regional recurrence (LRR).~* Tumors may be either HPV+ or HPV-.~* Tumor must be PD-L1 positive, defined as CPS ≥ 1.~* Be willing to provide tissue; newly obtained biopsy specimens or formalin-fixed, paraffin-embedded (FFPE) block specimens.~* Female subjects of childbearing potential have a negative urine or serum pregnancy test within 7 days prior to enrollment. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required. It is allowed that the test at the same day at 7 days prior to enrollment. And male / female subjects of childbearing potential must agree to use an adequate method of contraception starting with signing the informed consent through 120 days after the last dose of study medication.~* Demonstrated adequate organ function as defined in following criteria. All screening labs should be performed within 14 days of enrollment. Note: Subject must not have taken transfusion, hematopoietic agent; granulocyte-colony stimulating factor (G-CSF) etc., and/or oxygen supplementation within 7 days before the screening labs.~  * Absolute neutrophil count (ANC)\>=1,000 /mm3~ * Platelets\>=100,000 /mm3~ * Hemoglobin\>=9.0 g/dL~ * Serum total bilirubin\<=2.0 mg/dL~ * Aspartate aminotransferase (AST) (SGOT) and alanine aminotransferase (ALT) (SGPT) \<= 2.5x Upper limit of normal (ULN). For subjects with liver metastases\<= 5x ULN.~ * Serum creatinine\<= 1.5 mg/dL; or if serum creatinine \>1.5 mg/dL, measured or calculated creatinine/clearance\>=60 mL/min (Cockcroft-Gault formula).~* Life expectancy of ≥ 6 months from the first OBP-301 treatment.~* Understand the study requirements and the treatment procedures, and is willing to comply with all specified follow- up evaluations, and provides written informed consent before any study-specific tests or procedures are performed.~Exclusion Criteria:~* Is currently participating and receiving study therapy or has participated in a study of an investigational agent and received study therapy within 2 weeks (chemotherapy, small molecule), or 3 weeks (antibody) of study Day 1.~* Has an active autoimmune disease that has required systemic treatment in past 2 years.~* Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy (greater than the equivalent of prednisone 20 mg/day) or any other form of immunosuppressive therapy within 7 days prior to study Day 1. Daily dose of maintenance prednisone 10mg or equivalent is allowable.~* Has known active central nervous system metastases and/or carcinomatous meningitis.~* Has a known additional malignancy that is progressing or requires active treatment, with the exception of stable/low grade tumors that are not expected to influence life-expectancy (e.g. skin SCC, basal cell, differentiated thyroid cancer, prostate cancer on hormonal therapy).~* Has received a live vaccine within 30 days of planned start of study therapy.~* Has a known history of Human Immunodeficiency Virus.~* Has known active Hepatitis B or Hepatitis C.~* Has known history of, or any evidence of active, non-infectious pneumonitis.~* Has an active infection requiring systemic therapy.~* Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.~* Is pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the trial, starting with the screening visit through 120 days after the last dose of trial treatment.~* Previous severe hypersensitivity to another monoclonal antibody.~* Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject's participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator.~* Prior intolerance related to severe (\>=grade 3) irAE to a prior anti-immune checkpoint inhibitor agent leading to discontinuation of anti-immune checkpoint inhibitor therapy.~* Any disorder or condition, or any medication that would put the patient at risk from bleeding after direct tumor injection.~* Not a candidate for SBRT given for potentially curative intent. All tumors must receive SBRT. For example, patients with locoregional neck recurrence without significant overlap with the previous radiation field, and who do not warrant SBRT for re-irradiation as per the treating radiation oncologist (e.g. out-of-field recurrence), will not be included in the study.~* Received prior immunotherapy with checkpoint inhibitors or other immunotherapy agents.
