For the definition of replacement therapy, see Section 7.3. 7. Active leptomeningeal disease or uncontrolled, untreated brain metastasis: Patients with a history of treated brain metastasis and, at the time of screening, asymptomatic stable central nervous system (CNS) metastases are eligible, provided they meet all the following: a. Brain imaging at screening shows no evidence of interim progression for at least 4 weeks by repeat imaging, and clinically stable for at least 2 weeks b. Have measurable disease outside the CNS c. Only supratentorial metastases allowed d. No ongoing requirement for corticosteroids as therapy for CNS disease; anticonvulsants at a stable dose allowed e. No stereotactic or whole-brain radiation within 14 days prior to enrollment 8. Major surgery = 2 weeks prior to starting study drug. Note: If patient received major surgery, he or she must have recovered adequately from the toxicity and/or complications from the intervention prior to starting study treatment. 9. Any active malignancy = 3 years before enrollment except for the specific cancer under investigation in this study and locally recurring cancer that has been treated curatively (e.g., resected basal or squamous cell skin cancer, superficial bladder cancer, or carcinoma in situ of the prostate, cervix, or breast) 10.

| Measure | Time frame |
|---|---|
| Secondary end point(s): Phase 1 • Incidence of changes in individual tumor sizes, inflammation, necrosis and erythema in injected and uninjected tumors • Incidence of clearance of RP1 from blood and urine before and after each injection • Rate of RP1 detection on: exterior of the dressing, injected lesions, saliva/oral mucosa and lesions that are herpetic in appearance • Changes in HSV-1 antibody levels during treatment compared to baseline Phase 2 Efficacy Endpoints • ORR, DOR, CR rate, DCR, PFS, and 1-year and 2-year survival rates according to investigator review • ORR, DOR, CR rate, DCR, and PFS will also be assessed by independent central review for the anti-PD1 failed cutaneous melanoma cohort • Time to next therapy;Timepoint(s) of evaluation of this end point: Response assessments will be carried out every 8 weeks (±7 days) after Day 1 OS assessed at 1 year and 2 year timepoints RP1 detection for the first three doses at pre-dose, 6 (± 2hr) hours, 21 hours (±3 hr) and 48 hours (± 6hr) and also immediately prior to dosing at the fourth dose and at both the 30 day and 60 day follow-up visits. In the anti-PD1 refractory cutaneous melanoma cohort, patients will be followed for a total of 60 months from the start of study treatment. | — |
