Summary
This research study involves two investigational drugs, an Activator Ligand (INXN-1001) in combination with an Adenovirus Vector Engineered to Express hIL-12 (INXN-2001). IL-12 is a protein that may improve the body's natural response to disease by enhancing the ability of the immune system to kill tumor cells and may interfere with blood flow to the tumor.
The main purpose of this study is to evaluate the safety and tolerability of tumor injections of INXN-2001 given in combination with different doses of INXN-1001.

Eligibility Criteria
Inclusion Criteria
- Males or females of all races ≥ 18 years of age, who have provided written informed consent prior to completing any study specific procedure.
- Unresectable Stage III or Stage IV melanoma arising from any site other than ocular melanoma.
- A minimum of 2 accessible nonvisceral lesions (shortest diameter ≥1 cm) or palpable tumor-involved lymph nodes (shortest diameter ≥1.5 cm).
- ECOG performance status of 0 or 1 (Appendix 1).
- Adequate bone marrow, liver, and renal function.
- An expected survival of at least approximately 6 months.
- Male and female subjects must agree to use a highly reliable method of birth control (expected failure rate less than 5% per year) from the screening visit through 28 days after the last dose of study drug.
Exclusion Criteria
- Any prior anti-cancer therapy or investigational agent within 28 days prior to the first dose of study drug. (NOTE: For the expansion cohort ONLY, if subjects received ipilimumab, a 90-day washout period since last dose of ipilimumab is required. If subjects received other immunomodulating therapies (eg, anti-PD1 antibodies), the medical monitor should be contacted and an evaluation will be made.)
- Clinically significant infection requiring systemic antibacterial, antifungal, or antiviral therapy within 2 weeks of the first dose of study drug.
- History of HIV infection.
- Active autoimmune disease requiring steroids (>10 mg prednisone or comparable) or other immunosuppressive therapy (e.g., methotrexate, etc.).
- Documented symptomatic brain metastases. Screening for brain lesions by CT or MRI is not required for all potential subjects; however, if there are any neurological signs or symptoms consistent with brain metastases, then a brain CT or MRI should be performed as clinically indicated.
- Any medications that induce, inhibit or are substrates of CYP450 3A4 within 7 days prior to the first dose of study drug.
- Prior history of hematopoietic stem cell transplant or organ allograft.
- Other concurrent clinically active malignant disease, with the exception of other cancers of the skin.
- Females who are nursing or pregnant.
- Subjects who have a history of hypersensitivity that may relate to any component of the study drugs, e.g. to benzoic acid since INXN-1001 contains two benzene rings.
- Unstable or clinically significant concurrent medical condition that would, in the opinion of the investigator, jeopardize the safety of a subject and/or their compliance with the protocol.
