* = 2.5 × ULN OR
* = 5 × ULN for patients with liver metastases
4. Coagulation:

* International normalized ratio or prothrombin time (PT) = 1.5 × ULN unless patient is receiving anticoagulant therapy, and as long as PT or partial thromboplastin time (PTT) is within therapeutic range of intended use of anticoagulants
* Activated partial thromboplastin time (aPTT) = 1.5 × ULN unless patient is receiving anticoagulant therapy, and as long as PT or PTT is within therapeutic range of intended use of anticoagulants
5. Have provided 2 tissue biopsy samples taken of the target lesion (Lesion A) as a single biopsy split into 2 samples or 2 separate biopsies that meet the minimal sample size requirement per the study laboratory manual. One sample is for determining PD-L1 expression level by immunohistochemistry and can be an archival sample of the anticipated target lesion that has been collected within 3 months of screening. The other sample is for RNA expression profiling and must be a fresh biopsy.
6. Life expectancy of at least 6 months
7. Female patients of childbearing potential, as defined in Section 5.2.1, must have a negative urine or serum pregnancy test within 72 hours prior to taking the first dose of trial treatment. If the urine test is positive or cannot be confirmed as negative then a serum test is required which must be negative for the patient to enroll. Women of childbearing potential (WOCBP) must be willing to use 2 medically acceptable methods of contraceptive from Day 1 through 120 days after the last dose of trial treatment. The 2 medically acceptable birth control methods can be either 2 barrier methods or a barrier method plus a hormonal method to prevent pregnancy. The following are considered adequate barrier methods of contraception: diaphragm, condom (by the partner), copper intrauterine device, sponge, or spermicide as per local regulations or guidelines. Appropriate hormonal contraceptives will include any registered and marketed contraceptive agent that contains an estrogen and/or a progestational agent (including oral, subcutaneous, intrauterine, or intramuscular agents).

Male patients of reproductive potential, as described in Section 5.2.1, must agree to use an adequate method of contraception from Day 1 through 120 days after the last dose of trial treatment.

Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the patient.

[Inclusion Criteria (Phase 1 only: Melanoma)]
8. Histologically or cytologically confirmed unresectable or metastatic (stage IV) melanoma
9. For Phase 1 Escalation Cohorts 1-4, must have at least 1 lesion that qualifies as a target lesion per RECIST v1.1 except for the minimum measurement of 10 mm in diameter for superficial lesions, is easily accessible (palpable or can be visualized by ultrasound), and is amenable to multiple intratumoral injections.

If superficial, the target lesion must measure at least 10 mm in diameter, be measured by calipers, and be documented photographically. Tumor lesions situated in a previously irradiated area, or in an area subjected to other loco-regional therapy, are usually not considered measurable unless there has been demonstrated progression in the lesion. Approval from the Medical Monitor is required to inject a previously radiated lesion.

[Inclusion Criteria (Phase 2 only: HNSCC)]
14. Histologically or cytologically confirmed recurrent or metastatic HNSCC that could not be treated with curative intent
15. Must have at least 1 lesion that qualifies as a target lesion per RECIST v1.1, and which must be easily accessible (palpable or can be visualized by ultrasound) and amenable to multiple intratumoral injections. The target lesion should be of sufficient size such that the required tumor biopsies do not significantly affect tumor assessment per RECIST v1.1. Tumor lesions situated in a previously irradiated area, or in an area subjected to other loco-regional therapy, are usually not considered measurable unless there has been demonstrated progression in the lesion. Approval from the Medical Monitor is required to inject a previously radiated lesion.
16. Expansion Cohort 4: Must have documented confirmed PD per RECIST v1.1 on a prior treatment regimen containing an anti-PD-1/L1 drug (see Appendix 6 for definition of PD per RECIST v1.1)
17. Expansion Cohort 7: Must have all of the following:

1. Received at least 2 doses of an anti-PD-1/L1 therapy, where the last dose of anti-PD-1/L1 therapy was within 6 months of study enrollment (Day 1)
2. Refractory response, ie, PD occurred within 3 months duration of the start of treatment on anti-PD-1/L1 therapy; OR resistant response, ie, PD occurred beyond 3 months duration of treatment on anti-PD-1/L1 therapy and within 6 months after the last dose of treatment on anti-PD-1/L1 therapy

This exception does not include carcinomatous meningitis which is excluded regardless of clinical stability.
16. Use of any investigational agent within the last 28 days prior to study enrollment
17. Has received a live-virus vaccination within 30 days of planned treatment start. Seasonal flu vaccines that do not contain live virus are permitted.
