The Register is based on the study HIT 2000 that recruited patients until 31.12.2011. All german patients with intracranial medulloblastoma, CNS-PNET, ependymoma can be included in the register. Object of the register is to maintain the quality of diagnostic standard by using of central review (Neuroradiology, Pathology, and cranio spinal fluid (CSF) cytology).

Furthermore, the register should enable to continue the collection of epidemiologic data and biological material (tumor material, CSF, and blood) for associated studies.

Single dose of HSV-1 (G207) infused through catheters into region(s) of tumor defined by MRI. If G207 is safe in the first two cohorts of patients, subsequent patients will receive a single dose of G207 infused through catheters into region(s) of tumor defined by MRI followed by a 5 Gy dose of radiation to the tumor given with 24 hours of virus inoculation.

G207

Gregory K Friedman, M.D.

This study is a clinical trial to determine the safety of injecting G207 (a new experimental virus therapy) into a recurrent or progressive brain tumor. The safety of combining G207 with a single low dose of radiation, designed to enhance virus replication and tumor cell killing, will also be tested.

Outcomes for children with recurrent or progressive supratentorial malignant brain tumors are very poor, and there are a lack of effective salvage therapies once a patient fails standard treatments.

G207 is an oncolytic herpes simplex virus-1 (HSV) that has been successfully engineered to introduce mutations in the virus that enable it to selectively replicate in and kill cancer cells, but not normal cells. Replication of G207 in the tumor not only kills the infected tumor cells, but causes the tumor cell to act as a factory to produce new virus. These virus particles are released as the tumor cell dies, and can then proceed to infect other tumor cells in the vicinity, and continue the process of tumor kill. In addition to this direct oncolytic activity, the virus engenders an anti-tumor immune response; the virus is immunogenic and produces a debris field which exposes cancer cell antigens to immune cells which can target other cancer cells. Thus, the oncolytic effect of the virus and the immune response that the virus stimulates provide a one-two punch at attacking cancer cells. In preclinical studies, a single 5 Gy dose of radiation within 24 hours of virus inoculation to the tumor increased virus replication and tumor cell killing.

The University of Alabama at Birmingham has conducted three phase I trials of G207 injected into the recurrent tumor alone or combined with a single dose of radiation in adults with recurrent high-grade gliomas. In these trials, high doses (up to 3 x 10\^9 plaque-forming units) of virus were safely injected directly into the tumor or surrounding brain tissue without serious toxicities. A maximum tolerated dose was not reached in all 3 trials. Radiographic and neuropathologic evidence of an antitumor response was seen in some patients. Preclinical laboratory studies have demonstrated that a variety of aggressive pediatric brain tumor types are sensitive to G207.

This study is a phase I, open-label, single institution clinical trial of G207 alone or combined with a single low dose of radiation in children with recurrent or progressive supratentorial brain tumors. The primary goal is to determine safety. The secondary aims are to obtain preliminary information on the effectiveness of and immune response to G207.

A traditional 3 + 3 design will be used with four patient cohorts. The first two cohorts will receive G207 at one of two doses, and the second two cohorts will receive G207 at one of two doses followed by a 5 Gy dose of radiation.

All events with a Grade 3 or above toxicity (defined by the CTCAE v4.0) will be tabulated by event and by relationship to G207.

HSV-1 antibody titers will be checked by ELISA prior to the administration of G207 and at regular intervals after treatment.

Saliva, blood and conjunctival secretions will be checked by polymerase chain reaction (PCR) and culture at regular intervals for evidence of HSV shedding and/or viremia.

Time after G207 administration to clinical and radiographic disease progression will be evaluated.

The overall survival for each patient receiving G207 will be calculated.

A modified Lansky score (for children under 16 years of age) or Karnofsky score (for children 16 and older) will be recorded and measured serially with the pre-treatment score.

Quality of life will be measured with questionnaires taken at baseline (before administration of G207) and at specified times thereafter.
