NCT01811992

Brief Summary

Despite the marginal improvements in survival of patients suffering from malignant glioma treated with gene therapy vectors, the clinical trials conducted so far using viral vectors, in particular adenoviral vectors, have proven that the use of adenoviral vectors is a safe therapeutic approach, even in large, multicenter, phase 3 clinical trials. Treatment of malignant glioma using gene transfer modalities typically consists of surgical debulking of the tumor mass followed by the administration of the viral vectors into the brain tissue surrounding the tumor cavity. This study will combine direct tumor cell killing (TK) and immune-mediated stimulatory (Flt3L) gene transfer approaches delivered by first generation adenoviral vectors.

Outcome Measures

Primary Outcomes (1)

  • Maximum Tolerated Dose (MTD)

    Vectors AdhCMV- TK and Ad-hCMV-Flt3L were administered at time of surgery and the MTD determined by dose-limiting toxicities. Toxicities assessed and graded by the NCI Common Terminology Criteria for Adverse Events (CTCAE) v4.0.

    21 days post administration of study vectors

Secondary Outcomes (1)

  • Number of Patients Alive at 12 and 24 Months

    24 Months

Study Arms (1)

Dose escalation of Ad-hCMV-TK and Ad-hCMV-Flt3L

EXPERIMENTAL

This protocol is a dose escalation study of Ad-hCMV-TK and Ad-hCMV-Flt3L infused at the time of surgical resection followed by systemic oral administration of valacyclovir in addition to current standard of care with temozolomide and radiotherapy. Eligible subjects will be enrolled in six sequential dosing cohorts: * A= Ad-hCMV-TK: 1x10\^10 vp and Ad-hCMV-Flt3L: 1x10\^9 vp * B= Ad-hCMV-TK: 1x10\^11 vp and Ad-hCMV-Flt3L: 1x10\^9 vp * C= Ad-hCMV-TK: 1x10\^10 vp and Ad-hCMV-Flt3L: 1x10\^10 vp * D= Ad-hCMV-TK: 1x10\^11 vp and Ad-hCMV-Flt3L: 1x10\^10 vp * E= Ad-hCMV-TK: 1x10\^10 vp and Ad-hCMV-Flt3L: 1x10\^11 vp * F= Ad-hCMV-TK: 1x10\^11 vp and Ad-hCMV-Flt3L: 1x10\^11 vp Subjects will be treated sequentially with a minimum of 21 days before treatment of new subjects within a cohort or before dose escalation.

Interventions

Two adenoviral vectors will be used, each to deliver one of the therapeutic genes. Both vectors are human serotype 5, replication-defective, first generation adenoviral vectors deleted in E1a and E3 viral encoding regions. Each vector will constitutively express their respective therapeutic transgene (i.e. HSV1-TK or Flt3L) under the control of the human cytomegalovirus promoter (hCMV). Valacyclovir treatment will begin 1-3 days after vector administration at a dose of 2 grams given orally 3X per day for 14 days. A second course of valacyclovir will be given beginning Week 10. Radiation and chemotherapy will be administered as per standard of care.

Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Newly diagnosed supratentorial brain lesion compatible with a high grade glioma by MR (magnetic resonance) with no prior treatment with either gene therapy, chemotherapy or radiation treatments that is amenable to attempted gross total resection (GTR).Intraoperative histological frozen section at the time of tumor resection should be compatible with high-grade glioma. If intraoperative diagnosis is not high grade glioma, the patient will not be enrolled. "High grade glioma" can include:Glioblastoma multiforme (WHO grade IV); Anaplastic astrocytoma (WHO grade III); Anaplastic oligodendroglioma (WHO grade III); and Anaplastic ependymoma (WHO grade III).
  • Karnofsky score ≥70 (Karnofsky scoring system used to quantify general well-being and activities of daily life; scores range from 0 to 100 where 100 represents perfect health and 0 represents death)
  • CBC (complete blood count)/differential obtained within 14 days prior, with adequate bone marrow function defined as follows:
  • Absolute neutrophil count (ANC) ≥ 1,500 cells/mm3;
  • Platelets ≥ 100,000 cells/mm3;
  • Hemoglobin ≥ 10.0 g/dl (Note: The use of transfusion or other intervention to achieve Hgb ≥10.0 g/dl is acceptable.);
  • Adequate renal function, as defined below:
  • BUN (blood urea nitrogen) ≤ 30 mg/dl within 14 days prior.
  • Creatinine ≤ 1.7 mg/dl within 14 days prior.
  • Adequate hepatic function, as defined below:
  • Bilirubin ≤ 2.0 mg/dl within 14 days prior.
  • ALT (alanine aminotransferase)/AST (aspartate aminotransferase) ≤ 3x laboratory upper limit of normal within 14 days prior.
  • Male and female; both genders must use contraception if of reproductive capacity
  • Capable of informed consent
  • years of age
  • +1 more criteria

You may not qualify if:

  • Tumors infiltrating the cerebellum, bilateral corpus callosum ("butterfly glioma"), ventricular system, or brain stem
  • Infratentorial high grade glioma
  • Primary central nervous system (CNS) disease that would interfere with subject evaluation
  • Current diagnosis of other cancer except curative cervical cancer in situ, basal or squamous cell carcinoma of the skin.
  • HIV, Hepatitis B, Hepatitis
  • Active systemic infection

  • Serious medical conditions (CHF (congestive heart failure), angina, diabetes mellitus, Chronic obstructive pulmonary disease, abnormal bleeding diathesis)
  • Any contraindication for undergoing MRI (magnetic resonance imaging)
  • Pregnant or lactating females
  • Unacceptable anesthesia risk
  • Evidence of bleeding diathesis or use of anticoagulant medication or any medication that may increase the risk of bleeding that cannot be stopped prior to surgery.
