Women of child-bearing potential (WCBP) and men must agree to use adequate contraception prior to study entry, while on study treatment, and for six months after receiving last dose of T3011. WCBP must have a negative serum pregnancy test prior to W1D1. 10. Last dose of previous anticancer therapy ≥ 21 days, radiotherapy > 21 days, or surgical intervention > 21 days prior to the first dose of T3011. 11. Recovered from all prior anticancer therapy toxicities. 12. Willingness to provide fresh tumor biopsy specimens as specified in the Schedule of Assessments. 13. Capable of understanding and complying with protocol requirements. 14. Signed and dated institutional review board/independent ethics committee-approved informed consent form before any protocol-directed screening procedures are performed.
Exclusion Criteria
- Have only uninjectable tumors.. 2. Patients with injectable tumors impinging upon major airways or blood vessels. 3. HNSCC only: Prior re-irradiation field containing carotid artery. 4. Greater than 3 distant metastatic lymph node regions and/or metastatic lesions or the largest distant metastases with a diameter of more than 3 cm (non-sarcoma)/5 cm (sarcoma) unless the lesion is to be injected. 5. Prior treatment with another OV (including T-VEC), tumor vaccines, cellular therapy or gene therapy. 6. Prior intolerance to anti-PD-(L)1 monoclonal antibody or history of immunotherapy related non-infectious pneumonitis/interstitial lung disease. 7. Prior treatment with anti-PD-(L)1 monoclonal antibody in combination with IL-12. 8. Requires continued concurrent therapy with any drug active against HSV. 9. Live vaccines, attenuated vaccines within 4 weeks prior to initiation of study treatment (participants vaccinated with inactivated vaccines can be enrolled. 10. Primary or acquired immunodeficient states. 11. Pregnant or lactating. 12. Prior organ transplantation. 13. Active hepatitis B virus, hepatitis C virus, and HIV infection or a positive serological test at Screening within 14 days of dosing with T3011. 14. Active autoimmune disease or medical conditions requiring chronic steroid or immunosuppressive therapy within 4 weeks prior to first administration of study treatment. 15. History of or current central nervous system metastases. 16. History of seizure disorders within 6 months of Screening. 17. Active oral or skin herpes lesion at Screening. 18. Active interstitial lung disease (ILD)/pneumonitis or a history of ILD/pneumonitis requiring treatment with systemic steroids. 19. Congestive heart failure, active coronary artery disease, unevaluated new onset angina within 3 months or unstable angina, or clinically significant cardiac arrhythmias. 20. History of allergic reactions attributed to compounds of similar biological composition to HSV-1, IL-12, or anti-PD-1 monoclonal antibody. 18. Active infection with SARS-CoV-2 virus. 21. Participants with moderate to large amount of pleural effusion, ascites or pericardial effusion who need drug or medical intervention. 22. Other systemic conditions or organ abnormalities that, in the opinion of the investigator, may interfere with the conduct and/or interpretation of the current study.

Detailed Description
This is a Phase 1/2a, open-label, first-in-human study of T3011 given via intratumoral (IT) injection as a single agent and in combination with IV pembrolizumab in participants with advanced or metastatic solid tumors. The Phase 1 portion of the study is a single agent dose escalation which will use a 3+3 design to evaluate escalating doses of T3011. Total enrollment will depend on the toxicities and/or activity observed, with approximately 15 to 30 evaluable participants enrolled. Once the RP2D is established Phase 2a Part 1 will enroll approximately 10 participants with locally recurrent or metastatic melanoma (in Arm A) 23 to 53 participants with HNSCC in Arm B, 40 to 80 participants with sarcoma in Arm C and 10 participants with cSCC in Arm D. During Phase 2a Part 1 the safety, tolerability, and preliminary efficacy of T3011 as a single agent will be evaluated. Phase 2a Part 2 will enroll in parallel to Phase 2a Part 1 once the RP2D is established. The safety, tolerability, and preliminary efficacy of IT T3011 given in combination with IV pembrolizumab will be evaluated in 15 participants with histologically or pathologically confirmed metastatic NSCLC (Arm E). A rollover arm is also included in this study to allow participants who have documented progression on T3011 alone to receive T3011 in combination with pembrolizumab if considered eligible.
