Brief Summary:

Patients with relapsed solid tumors such as sarcomas and neuroblastoma have a poor survival, generally < 20%. There is an urgent need for new treatments that are safe and effective.

HSV1716, an oncolytic virus, is a mutant herpes simplex virus (HSV) type I, deleted in the RL1 gene which encodes the protein ICP34.5, a specific determinant of virulence. Mutants lacking the RL1 gene are capable of replication in actively dividing cells but not in terminally differentiated cells - a phenotype exploited to selectively kill tumor cells. In previous clinical studies, HSV1716 has been shown to be safe when injected at doses up to 10^5 plaque forming units (pfu) directly into human high-grade glioma and into normal brain adjacent to tumour, following excision of high-grade glioma. In an extension study, HSV1716 has been shown to be safe when injected at a dose of up to 10^6 pfu directly into brain tumours. Replication of HSV1716 in human glioblastoma in situ has been demonstrated. Following a single administration of HSV1716 by direct injection into active recurrent tumor or brain adjacent to tumor, some patients have lived longer than might have been expected. This study seeks to evaluate the safety of a single injection of HSV1716 in the treatment of extracranial solid tumors in adolescents and young adults.

HSV1716 has also proved safe when given by direct intra-tumoural injection in patients with squamous carcinoma of the head and neck, and in patients with malignant melanoma.

Replication of HSV mutants in human sarcomas and neuroblastoma in cultured cells and human xenograft models has been demonstrated.

This study is designed in two parts. PART 1 of the study specifies a single dose of virus. Participants who experience at least stable disease or relapse following a determination of stable disease, may qualify for subsequent doses in PART 2. PART 2 requires signing of a separate consent.

Official Title: A Phase I Dose Escalation Study of Intratumoral or Intravenous Herpes Simplex Virus-1 Mutant HSV1716 in Patients With Refractory Non-Central Nervous System (Non-CNS) Solid Tumors
Study Start Date : March 2010
Actual Primary Completion Date : March 19, 2018
Actual Study Completion Date : March 19, 2018

Arm Intervention/treatment
Experimental: HSV1716 - Intratumoral route
Research participants with localized disease receiving HSV1716 as an intratumoral injection
Biological: HSV1716
Experimental: HSV1716 - intravenous
Research participants with metastatic disease receiving HSV1716 intravenously
Biological: HSV1716

Primary Outcome Measures :
  1. To determine whether intratumoral injection or intravenous infusions of HSV1716 is safe in adolescents and young adults with non-CNS solid tumors. [ Time Frame: Dose limiting toxicities will be assessed at 28 days after injection of HSV1716. ]

Secondary Outcome Measures :
  1. To measure antiviral immune response in patients with refractory cancer treated with HSV1716. [ Time Frame: Antiviral immune response will be assessed 28 days after injection. Beginning at 1.5 years post injection assessments will occur every 6 months. Beginning 5 years after the injection, assessments will occur annually until 15 years post injection. ]

Layout table for eligibility information
Ages Eligible for Study:   7 Years to 30 Years   (Child, Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

Inclusion of Women and Minorities: The study is open to all participants regardless of gender or ethnicity.

Inclusion for intratumoral injection: Subject must have 1-3 lesions amenable to HSV1716 administration by needle if superficial; by needle and/or catheter if deep or pulmonary, via interventional radiology without undue risk. Lesion(s) must meet size criteria specified in section 4.4.9.

Inclusion for intravenous administration: Subject must have metastatic disease or a lesion not deemed suitable for direct injection.

  • Age: Subjects must be greater than or equal to 7 years and less than or equal to 30 years of age at the time of signing consent (study entry);
  • Histologic Diagnosis: Subjects must have had histologic verification a non-CNS solid tumor at original diagnosis. The tumor must be amenable to HSV1716 administration without undue risk. Disease must be considered refractory to conventional therapy or for which no conventional therapy exists.
  • Metastatic Disease: Subjects who have metastasis to the brain are eligible for the intratumoral arm of this study; however, no metastatic sites within the brain will be considered for injection. Subjects who have metastasis to the brain are eligible for the intravenous arm of this study only if those metastases have been treated and are no longer active.
  • Performance Level: Karnofsky greater than or equal to 50. Subjects who are unable to walk because of paralysis, but who are up in a wheelchair will be considered ambulatory for the purpose of assessing the performance score.
  • Subjects must have fully recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy prior to entering this study;
  • Myelosuppressive chemotherapy: Must not have received within 28 days of entry onto this study (42 days if prior nitrosourea) accompanied by hematopoietic recovery, or 14 days of stopping non-myelosuppressive therapy as long as hematopoietic requirements are met;
  • Biologic (anti-neoplastic agent): Must not have received within 7 days of entry onto this study (21 days if prior VEGF-Trap and at least 3 half-lives after last dose of a monoclonal antibody). For biologic agents that have known adverse events occurring beyond 7 days after administration, this period must be extended beyond the time during which adverse events are known to occur;
