简要总结
This research study involves an investigational product: Ad-RTS-hIL-12 given with veledimex for production of human interleukin-12 (IL-12). IL-12 is a protein that can improve the body's natural response to disease by enhancing the ability of the immune system to kill tumor cells and may interfere with blood flow to the tumor.
Nivolumab is an antibody (a kind of human protein) that is being tested to see if it will allow the body's immune system to work against glioblastoma tumors. Opdivo (Nivolumab) is currently FDA approved in the United States for melanoma (a type of skin cancer), non-small cell lung cancer, renal cell cancer (a type of kidney cancer), Hodgkin's lymphoma but is not approved in glioblastoma. Nivolumab may help your immune system detect and attack cancer cells. Ad-RTS-hIL-12 and veledimex will be given in combination with Nivolumab to enhance the IL-12 mediated effect observed to date.
The main purpose of this substudy is to evaluate the safety and tolerability of a single tumoral injection of Ad-RTS-hIL-12 given with oral veledimex in combination with nivolumab.
详细描述
Eligible patients will receive one dose of nivolumab, via infusion, one week prior to standard of care craniotomy and tumor resection (subtotal or total). On the day of surgery, patients will receive one dose of veledimex before the resection procedure. Ad-RTS-hIL-12 will be administered by free-hand injection. Patients will continue on oral veledimex for 14 days. Following veledimex, patients will receive nivolumab via infusion every two weeks.
The study is divided into three periods: the screening period, the treatment period and the follow-up period.

- •Evidence of tumor recurrence/progression by magnetic resonance imaging (MRI) according to response assessment in neuro-oncology (RANO) criteria after standard initial therapy
- •Previous standard-of-care antitumor treatment including surgery and/or biopsy and chemoradiation. At the time of registration, subjects must have recovered from the toxic effects of previous treatments as determined by the treating physician. The washout periods from prior therapies are intended as follows: (windows other than what is listed below should be allowed only after consultation with the Medical Monitor)

- •Vaccine-based therapy: 3 months
- •Able to undergo standard MRI scans with contrast agent before enrollment and after treatment
- •Karnofsky Performance Status ≥70%
- •Adequate bone marrow reserves and liver and kidney function, as assessed by the following laboratory requirements:
- •Hemoglobin ≥9 g/L
- •Lymphocytes >500/mm3
- •Absolute neutrophil count ≥1500/mm3
- •Platelets ≥100,000/mm3
- •Serum creatinine ≤1.5 x upper limit of normal (ULN)
- •Aspartate transaminase (AST) and alanine transaminase (ALT) ≤2.5 x ULN. For subjects with documented liver metastases, ALT and AST ≤5 x ULN
- •Total bilirubin < 1.5 x ULN
- •International normalized ratio (INR) and activated partial thromboplastin time (aPTT) within normal institutional limits
- •Male and female subjects must agree to use a highly reliable method of birth control (expected failure rate <5% per year) from the Screening Visit through 28 days after the last dose of study drug. Women of childbearing potential (perimenopausal women must be amenorrheic for at least 12 months to be considered of non-childbearing potential) must have a negative pregnancy test at screening.
- •Normal cardiac and pulmonary function as evidenced by a normal electrocardiogram (ECG) and peripheral oxygen saturation (SpO2) ≥90% by pulse oximetry
排除标准
- •Previous treatment with inhibitors of immunocheckpoint pathways (eg, anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CD137, or anti-CTLA-4 antibody) or other agents specifically targeting T cells
- •Radiotherapy treatment within 4 weeks or less prior to veledimex dosing
- •Subjects with clinically significant increased intracranial pressure (eg, impending herniation or requirement for immediate palliative treatment) or uncontrolled seizures
- •Known immunosuppressive disease, or autoimmune conditions, and/or chronic viral infections (eg, human immunodeficiency virus [HIV], hepatitis)
- •Use of systemic antibacterial, antifungal, or antiviral medications for the treatment of acute clinically significant infection within 2 weeks of first veledimex dose. Concomitant therapy for chronic infections is not allowed. Subjects must be afebrile prior to Ad-RTS-hIL-12 injection; only prophylactic antibiotic use is allowed perioperatively.
- •Use of enzyme inducing antiepileptic drugs (EIAED) within 7 days prior to the first dose of study drug. Note: Levetiracetam (Keppra®) is not an EIAED and is allowed.
- •Other concurrent clinically active malignant disease, requiring treatment, with the exception of non-melanoma cancers of the skin or carcinoma in situ of the cervix or nonmetastatic prostate cancer
- •Nursing or pregnant females
- •Prior exposure to veledimex
- •Use of medications that induce, inhibit, or are substrates of cytochrome p450 (CYP450) 3A4 within 7 days prior to veledimex dosing without consultation with the Medical Monitor
- •Presence of any contraindication for a neurosurgical procedure
- •Unstable or clinically significant concurrent medical condition that would, in the opinion of the Investigator or Medical Monitor, jeopardize the safety of a subject and/or their compliance with the protocol. Examples include, but are not limited to: unstable angina, congestive heart failure, myocardial infarction within 2 months of screening, ongoing maintenance therapy for life-threatening ventricular arrhythmia or uncontrolled asthma.
- •History of myocarditis or congestive heart failure (as defined by New York Heart Association Functional Classification III or IV), as well as unstable angina, serious uncontrolled cardiac arrhythmia, uncontrolled infection, or myocardial infarction 6 months prior to study entry.

结局指标
主要结局
Number of Participants With Adverse Events (AEs)
时间窗: 2 years and 4 months
Evaluation of adverse events as assessed by Common Terminology Criteria for Adverse Events (CTCAE) v4.03 will be based on the incidence, intensity and type of adverse event. AEs will be regarded as treatment-emergent adverse events (TEAEs) during the treatment period regardless of relationship to study drug if: • The AE occurred or worsened from baseline during or after administration of the first dose of study drug (on or after Day 0).
Number of Participants With Veledimex Dose Compliance
时间窗: From Day 0 through Day 14 for each participant
Evaluation will be based on expected dose compliance. Subjects were instructed to document veledimex dosing compliance in a subject diary, including the time each dose was taken, the time of the last meal prior to administration of veledimex, the number of capsules taken, whether the subject missed any veledimex doses, and reason for any missed doses. Investigational product container(s) with any remaining capsules were returned to the study staff on Day 15, and staff assessed dose compliance.
