Eligibility Criteria

2 Years - 21 Years (Child, Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Age between 2 and 21 years

Non-CNS solid tumors are eligible and are likely to include such histologies as neuroblastoma, Wilms' tumor, rhabdomyosarcoma, Ewing's sarcoma, osteosarcoma, non-rhabdomyosarcoma soft tissue sarcomas, and malignant peripheral nerve sheath tumors.
  • Cancer is not surgically resectable for cure
  • At least one measurable tumor mass by CT/MRI (i.e. lesion that can accurately be measured in at least one dimension with longest diameter ≥ 1 cm) and that can be injected by direct visualization/palpitation or by imaging-guidance (CT or ultrasound)
  • Expected survival for approximately 8 weeks or longer
  • Lansky Score ≥ 50
  • Total bilirubin ≤ 2.5 × ULN
  • AST, ALT ≤ 2.5 × ULN (if liver tumor(s) present: AST/ALT ≤ 5 x ULN)

Exclusion Criteria:

  • Pregnant or nursing infant

  • Treatment of the injected tumor(s) with radiotherapy, chemotherapy, surgery, or an investigational drug within 3 weeks prior to first treatment
  • Clinically significant active infection or uncontrolled medical condition considered high risk for investigational new drug treatment (e.g. pulmonary, neurological, cardiovascular, gastrointestinal, genitourinary)
  • History of exfoliative skin condition (e.g. severe eczema, ectopic dermatitis, or similar skin disorder) requiring systemic therapy
  • Clinically significant and/or rapidly accumulating ascites, peri-cardial and/or pleural effusions (e.g. requiring drainage for symptom control)
  • Severe or unstable cardiac disease which may include, but is not limited to, any of the following within 6 months prior to screening: myocardial infarct, unstable angina, congestive heart failure, myocarditis, arrhythmias diagnosed and requiring medication, or any clinically-significant change in cardiac status
  • Current, active, progressing CNS malignancy, including carcinomatosis meningitis (definitively surgically resected or irradiated metastases allowed)

  • Use of anti-viral, anti-platelet or anti-coagulation medication (for example, heparin, warfarin, aspirin, ticlopidine, clopidogrel, dipyridamole) [Patients who discontinue such medications within 7 days prior to first treatment may be eligible for this study. Any required, chronic medications indicated for other medical issues should not be discontinued in order to meet eligibility criteria for this trial without consultation with both the patient and the treating physician.] Note: Low Dose Heparin to maintain patency of venous catheters is permitted.
  • Patients with benign tumors
  • Inability or unwillingness to give informed consent (patient or parent/guardian) or comply with the procedures required in this protocol
  • Vaccination with a live virus (i.e. measles, mumps, rubella, etc) < 30 days prior to first treatment
  • Patients with household contacts who meet any of these criteria will be excluded unless alternate living arrangements can be made during the patient's active dosing period and for three weeks following the last dose of study medication:

    • Women who are pregnant or nursing an infant
    • Children < 1 years old
    • People with skin disease (eczema, atopic dermatitis and related diseases)

5. Study Description

Brief Summary
This is a Phase I, open-label, dose-escalation trial of JX-594 (Pexa-Vec) in pediatric patients with advanced/metastatic, unresectable solid tumors refractory to standard therapy and/or the patient does not tolerate standard therapies. Tumors are likely to include neuroblastoma, lymphoma, Wilms' tumor, rhabdomyosarcoma, Ewing's sarcoma, osteosarcoma, non-rhabdomyosarcoma soft tissue sarcomas, and malignant peripheral nerve sheath tumors. Benign tumors are excluded. These tumor types were selected because evidence of biological activity was observed in cancer cells lines and ex vivo infected primary human tissue samples, specifically pediatric cancer types such as sarcomas and neuroblastomas.
