## Amended Eligibility Criteria (Version 15):
**Inclusion Criteria:**
Subjects enrolled in the study must meet all of the following inclusion criteria to be eligible.
* **Histopathologically-confirmed diagnosis:**
* Metastatic or unresectable cancer.
* Metastatic or locally and/or regionally advanced unresectable cutaneous squamous cell carcinoma (CSCC).
Note 1: CSCC subjects without radiographically measurable disease are not excluded if there is at least one lesion ≥ 10 mm in at least one dimension documented by color photography.
Note 2: Subjects with tumors that arise in the setting of chronic inflammation (Marjolin's ulcer) such as chronic wounds and/or scars are excluded.
* Metastatic or locally and/or regionally advanced unresectable Merkel cell carcinoma (MCC).
Note: MCC subjects without radiographically measurable disease are not excluded if there is at least one lesion ≥ 10 mm in at least one dimension documented by color photography.
* **Cohort A1:** Subjects who have not received prior systemic therapy for CSCC.
* **Cohort A2:** Subjects who have progressed while receiving a PD-1-blocking antibody or within 3 months of discontinuation.
PD-1-blocking antibody treatment may have been administered in the adjuvant, neoadjuvant, and/or metastatic setting.
The PD-1-blocking antibody must have been the most recent therapy received.
* **Cohort B1:** Subjects who have not received prior systemic therapy for MCC.
* **Cohort B2:** Subjects who have progressed while receiving a PD-1-blocking antibody or within 3 months of discontinuation.
PD-1-blocking antibody treatment may have been administered in the adjuvant, neoadjuvant, and/or metastatic setting.
The PD-1-blocking antibody must have been the most recent therapy received.
* **Cohort C1:** Subjects who have not received prior treatment with immune checkpoint inhibitors (ICIs).
* **Cohort C2:** Subjects who have received prior treatment with a PD-1-blocking antibody.
* **Cohort D:** Subjects with advanced or metastatic basal cell carcinoma (BCC) who are not candidates for curative surgery or curative radiation therapy and have not received prior hedgehog pathway inhibitor therapy and do not wish to receive or are not candidates for a hedgehog inhibitor.
* **Cohort E:** Subjects with advanced or metastatic non-small cell lung cancer (NSCLC) whose tumors have high PD-L1 expression (≥50%) and are not eligible for chemotherapy.
* **Cohort F:** Subjects with recurrent/metastatic HPV-positive, PD-L1 with CPS ≥ 1 oropharynx squamous cell carcinoma (OPSCC) who have not received prior systemic therapy in the recurrent/metastatic setting.
* **Measurable disease:** As defined by RECIST v1.1 and all of the following:
* At least one accessible lesion amenable to repeated IT injection.
* A previously irradiated lesion may be used as a target lesion if subsequent disease progression in that lesion (at least 20% increase in dimensions with a 5 mm absolute increase) was documented.
* Able to provide tissue from a core or excisional/incisional biopsy (fine needle aspirate is not sufficient).
A newly obtained biopsy (within 90 days before the start of study treatment) is preferred but an archival sample is acceptable if no intervening therapy was received.
* **Adequate organ function:** Based on most recent laboratory values within 3 weeks before first dose of study treatment on W1D1:
* Bone marrow function:
* Neutrophil count ≥ 1500/mm3
* Platelet count ≥ 100,000/mm3
* Hemoglobin concentration ≥ 9 g/dL
* Liver function:
* Total bilirubin ≤ 1.5 times the upper limit of normal (ULN) with the following exception: subjects with Gilbert's disease total serum bilirubin ≤ 3 times ULN
* Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 3 times the ULN
* Renal function:
* Estimated creatinine clearance ≥ 30 mL/min (Cockcroft-Gault) or measured creatinine clearance
* Coagulation:
* International normalized ratio (INR) or prothrombin time (PT) ≤ 1.5 times ULN unless subject is receiving anticoagulant therapy, in which case PT or partial thromboplastin time (PTT) is within the therapeutic range.
* Partial thromboplastin time (PTT) ≤ 1.5 times ULN unless subject is receiving anticoagulant therapy, in which case PT or PTT is within the therapeutic range.
* **Age:** ≥ 18 years at the time of consent.
* **Eastern Cooperative Oncology Group (ECOG) Performance Status:** 0 to 1 at Screening.
* **Ability to understand and comply:** With protocol requirements.
* **Women of childbearing potential:** Must have negative serum pregnancy test during Screening and be willing to use an adequate method of contraception from the time of consent until at least 150 days after the last dose of study treatment.
* **Subjects unable to provide written informed consent:** Are not eligible for the study.
**Exclusion Criteria:**
Subjects presenting with any of the following will not qualify for entry into the study:
* **Received radiation therapy (or other non-systemic therapy) to the target lesion(s) within 2 weeks before the first dose of study treatment on W1D1.** Subjects should have recovered (i.e., Grade ≤ 1 or at baseline) from radiation-related toxicities.
* **Received systemic pharmacologic doses of corticosteroids > 10 mg prednisone equivalent daily within 15 days before the first dose of study treatment on W1D1.** Replacement doses, topical, ophthalmic, and inhalational corticosteroids are permitted.
Stress-dose corticosteroids will be required in subjects with adrenal insufficiency.
* **Active pneumonitis or history of noninfectious pneumonitis requiring systemic therapy.**
* **Severe uncontrolled cardiac disease within 6 months of Screening, including but not limited to poorly controlled hypertension, unstable angina, myocardial infarction, congestive heart failure (New York Heart Association Class II or greater), pericarditis within the previous 6 months, cerebrovascular accident, or implanted or continuous use of a pacemaker or defibrillator.**
* **Known history of immunodeficiency.**
* **Known history of other malignancy that is progressing or requires active treatment within the past 3 years, except for the following:**
* Basal cell carcinoma of the skin, squamous cell carcinoma of the skin, localized prostate cancer with prostate-specific antigen (PSA) level below 4.0 ng/mL, in situ cervical cancer on biopsy or a squamous intraepithelial lesion on Papanicolaou smear, and thyroid cancer (except anaplastic).
* **Active infection requiring systemic therapy.**
* **Known or suspected active infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).**
* **Known or suspected active infection with human immunodeficiency virus (HIV), hepatitis B virus (HBV), or hepatitis C virus (HCV).**
* **Received a live attenuated vaccine within 30 days before the first dose of study treatment on W1D1.**
* **Major surgery (including complete oncologic resection) within 4 weeks prior to enrollment, or have not recovered adequately from the toxicities and/or complications from the intervention.** Minor surgeries (including routine resections of early stage CSCCs and BCCs that may be due to field cancerization) require a 7-day washout.
* **Pregnancy or breastfeeding or expecting to conceive children within the projected duration of the study, from the time of consent until at least 150 days after the last dose of study treatment.**
