Eligibility Criteria

Age12 Years+
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • I 1. Male or female who is 12 years of age or older at the time of signed informed consent.
  • I 2. Patients with histologically or cytologically confirmed unresectable or metastatic Stage IIIb through IV/M1a through M1d cutaneous melanoma, as per AJCC staging system, 8th edition).
  • I 3. Confirmed disease progression (PD) on an anti-PD-1 antibody treatment and an anti-CTLA-4 antibody treatment, administered as either a combination regimen (eg, nivolumab + ipilimumab) or in sequence.
  • Treatment with prior anti-PD-1 therapy must have continued for a minimum of 8 weeks (note: treatment with prior pembrolizumab therapy when administered every 6 weeks must have continued for a minimum of 12 weeks \[ie, 2 treatment cycles\]). Any number of doses of prior anti-CTLA-4 therapy may have been administered in combination with an anti-PD-1. The anti-PD-1-containing therapy must be the immediate prior line of treatment before randomization (for patients with BRAF mutation, see I 4).
  • Patients who in the physician's judgement are not candidates for treatment with an anti-CTLA-4 antibody (eg, due to documented clinically significant comorbidities or history of immune-related adverse events) are eligible for the study if they have confirmed PD on an anti-PD-1 antibody (including unresectable disease relapse during adjuvant therapy or \< 6 months from completion of adjuvant therapy).
  • Disease progression must have been confirmed and documented using clinical or radiological assessment by 2 assessments at least 4 weeks apart while being treated with an anti-PD-1 antibody and an anti-CTLA-4 antibody. Radiological confirmation of PD can occur during the Screening period for this study. Treatment with prior anti-PD-1 therapy must have continued from the time of initial tumor progression until confirmation of PD (ie, such that no doses of anti-PD-1 therapy were missed).
  • Note: If radiographic progression at the initial scan where PD was documented is accompanied by clear clinical progression, defined as a decline in performance status directly attributed to disease or increased disease-related symptoms, anti-PD-1 therapy does not need to continue. For patients with documented PD while on adjuvant therapy with an anti-PD-1 therapy, a confirmatory biopsy can be used in place of a confirmatory scan.
  • I 4. Has documented BRAF V600 mutation status or must consent to BRAF V600 mutation testing per local institutional standards during the Screening period. Patients with BRAF mutation should have received prior BRAF-directed therapy (with or without a MEK inhibitor) prior to randomization, unless deemed not clinically indicated at Investigator's discretion due to concurrent medical condition or prior toxicity.
  • Note: Prior exposure to BRAF-directed therapy (with or without a MEK inhibitor) includes treatment in the adjuvant setting. One line of BRAF-directed therapy (with or without a MEK inhibitor) can be the most recent systemic treatment administered before randomization.
  • I 5. Has least 1 measurable tumor of ≥ 1 cm in longest diameter (or shortest diameter for lymph nodes) and injectable lesion(s) of at least 1 cm in longest diameter.
  • I 6. Has adequate hematologic function, including:
  • White blood cell (WBC) count ≥ 2.0 × 109/L
  • Absolute neutrophil count (ANC) ≥ 1.5 × 109/L
  • Platelet count ≥ 75 × 109/L
  • Hemoglobin ≥ 8 g/dL (without packed red blood cell \[RBC\] transfusion within 2 weeks of dosing)
  • +9 more criteria

You may not qualify if:

  • E 1. Primary mucosal or uveal melanoma. E 2. More than 2 lines of systemic therapy for advanced melanoma. Note: One additional line of anti-PD-1 therapy in the adjuvant or neoadjuvant setting is allowed if the patient was free of treatment and of PD for at least 6 months and subsequently had confirmed PD on an anti-PD-1 and an anti-CTLA-4 antibody therapy administered in the advanced setting.
  • E 3. Known acute or chronic hepatitis B (defined as hepatitis B surface antigen \[HBsAg\] reactive) or known acute or chronic hepatitis C virus (defined as HCV RNA \[qualitative\] is detected).
  • Note: Patients who have been effectively treated are eligible for randomization. Patients must be negative for HBsAg and HCV RNA.
  • E 4. Known human immunodeficiency virus (HIV) infection. Note: Testing for HIV is not required unless mandated by local health authority or clinically indicated.
  • E 5. Active significant herpetic infections or prior complications of HSV-1 infection (eg, herpetic keratitis or encephalitis) or requires intermittent or chronic use of systemic (oral or IV) antivirals with known antiherpetic activity (eg, acyclovir).
  • Note: Patients with sporadic cold sores may be randomized if no active cold sores are present at the time of first dose of study treatment.
  • E 6. Had systemic infection requiring IV antibiotics or other serious active infection requiring antimicrobial, antiviral, or antifungal treatment within 14 days prior to the first dose.
  • E 7. Evidence of spinal cord compression or at high risk of spinal cord compression.
  • E 8. Known active central nervous system (CNS) metastases and/or carcinomatous meningitis at time of screening. Patients with known central nervous system metastases are eligible if they have received standard-of-care therapy for central nervous system disease (such as stereotactic radiosurgery or radical surgical resection followed by radiotherapy) and have evidence of disease stability on 2 subsequent scans performed at least at a 4-week interval.
  • E 9. Serum lactate dehydrogenase (LDH) \> 2 × ULN. E 10. Major surgery ≤ 2 weeks prior to starting study treatment. Note: Patients must have recovered adequately from all acute complications of all previous procedures prior to randomization.
  • E 11. Prior malignancy active within the previous 3 years, except for locally curable cancers that have apparently been cured, such as basal or squamous cell skin cancer, superficial bladder cancer, or carcinoma in situ (without invasive component) of the prostate, cervix, or breast.
  • E 12. History of significant cardiac disease including myocarditis or congestive heart failure (defined as New York Heart Association Functional Classification III or IV), or unstable angina, serious uncontrolled cardiac arrhythmia, cerebral vascular accident, or myocardial infarction within 6 months from first dose of VO.
  • E 13. History of life-threatening toxicity related to prior immune therapy except those that are unlikely to recur with standard countermeasures (eg, hormone replacement after adrenal crisis).
  • E 14. History or evidence of psychiatric, substance abuse (including IV substance abuse), or any other clinically significant disorder, condition, or disease (with the exception of those described above) that, in the opinion of the Investigator or the Medical Monitor, would pose a risk to patient safety or interfere with the study evaluation, procedures, or completion.
  • E 15. History or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the patient's participation for the full duration of the study, or is not in the best interest of the patient to participate, in the opinion of the treating Investigator.
