Re-Administration of C134 in Patients With Recurrent GBM (C134-HSV-1)

Exclusion Criteria

• •Patients who have had chemotherapy, cytotoxic therapy, immunotherapy or gene therapy within 6 weeks prior to entering the study, surgical resection within 4 weeks prior to entering the study, or have received experimental viral therapy at any time (e.g., adenovirus, retrovirus or herpesvirus\* protocol). Also, those who have not recovered from adverse events due to therapeutic interventions administered more than 4 weeks earlier.
• •Patients may not be receiving any other investigational therapeutic agents
• •Enhancing tumor diameter larger than 5.5 cm
• •History of allergic reactions or CTCAE version 5.0 Grade IV toxicity attributed to C134 or compounds of similar biologic composition to C134.
• •Tumor involvement which would require ventricular, brainstem, basal ganglia, or posterior fossa inoculation or would require access through a ventricle in order to deliver treatment.
• •Prior history of encephalitis, multiple sclerosis, or other CNS infection.
• •Active oral herpes lesion.
• •Concurrent therapy with any drug active against HSV (acyclovir, valaciclovir, penciclovir, famciclovir, ganciclovir, foscarnet, cidofovir).
• •Uncontrolled intercurrent illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or any other medical condition that precludes surgery. Also, psychiatric illness/social situations that would limit compliance with study requirements.
• •Required steroid increase within 2 weeks of scheduled C134 administration. When possible, the patient should be on a dexamethasone equivalent dose of ≤ 2mg daily at the time of treatment.
• •Known history of allergic reaction to IV contrast material that is not amenable to pre-treatment by UAB protocol.
• •Have a pacemaker, ferro-magnetic aneurysm clips, metal infusion pumps, metal or shrapnel fragments, or certain types of stents.
• •Received Bevacizumab (Avastin) therapy within 4 weeks of scheduled C134 administration.
• •Excluded patient groups Pregnant women are excluded from this study because C134 is a viral oncolytic therapy with unknown potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with C134 breastfeeding should be discontinued if the mother is treated with C134.
• •Immune deficient, because patients with immune deficiency will be unable to mount the anticipated immune response underlying this therapeutic rationale, HIV-seropositive patients are excluded from this study. Other treatment studies for this disease that are less dependent on the patients' immune response are more appropriate for HIV-seropositive patients.
