Eligibility
PART A DOSE ESCALATION

Inclusion Criteria: PART A Dose Escalation

1. 18-70 years of age

2. Histologically confirmed WHO grade IV glioblastoma

3. Unequivocal evidence of a tumor recurrence (any number of recurrences) or progression
after an initial treatment regimen (prior to enrollment on this study) consisting of
surgical intervention (tumor resection), radiation, and temozolomide chemotherapy (per
Stupp protocol), as assessed by MRI of the brain with and without contrast within 30
days prior to the initiation of injections of VBI-1901.

4. Recovery from the effects of surgery.

5. Corticosteroid (dexamethasone or equivalent) dosage = 4mg daily that has been stable
or decreasing for at least 5 days.

7. Karnofsky performance status (KPS) score = 70%.

8. Adequate organ function, including the following:

1. Absolute neutrophil count (ANC) = 1,000/µL, platelets = 100,000/µL

2. Serum creatinine < 1.5 × the upper limit of normal (ULN)

to use an acceptable form of contraception for heterosexual activity (i.e., oral
contraceptives, double barrier methods, hormonal injectable, transdermal, or implanted
contraceptives, tubal ligation, or vasectomy of their sexual partner(s) for > 30 days
before Screening, during the study, and for 60 days after the last dose of study
drug).

11. Female subjects without childbearing potential (spontaneous amenorrhea for > 12 months
or surgically sterilized by tubal ligation, hysterectomy, or bilateral oophorectomy >
6 months before Screening) are eligible for inclusion without contraceptive use
restriction.

12. Able and willing to comply with protocol requirements, including being able to have an
MRI in the opinion of the Investigator.

13. Written consent has been obtained.

14. Tumor specimen available for central pathological review.

Exclusion Criteria: PART A Dose Escalation

1. Contrast-enhancing residual tumor that is associated with either diffuse sub-
ependymal or leptomeningeal dissemination.

equivalent or requirement of increasing dose of systemic corticosteroids during the 7
days prior to the start of VBI-1901 treatment.

3. Evidence of HCMV viremia in serum of > 18,200 (4.3Log10) IU/mL using FDA approved

VBI- 1901, or stereotactic biopsy within 7 days prior to the start of VBI-1901.

5. Active infection requiring intravenous antibiotics or antiviral.

6. History of cancer (other than GBM or prostate) within the past 2 years that could
negatively impact survival and/or potentially confound tumor response assessments
within this study.

7. Known immunosuppressive disease or active systemic autoimmune disease such as systemic
lupus erythematosus, human immunodeficiency virus infection, Hepatitis B virus or
Hepatitis C virus infections. Subjects with vitiligo, type 1 diabetes mellitus,
hypothyroidism due to autoimmune condition only requiring hormone replacement therapy,
psoriasis not requiring systemic therapy, or conditions not expected to recur in the
absence of an external trigger are permitted to enroll.

8. Immunosuppressive agent within 4 weeks prior to the start of VBI-1901 treatment.

9. Evidence of intra-tumoral or peri-tumoral hemorrhage on baseline, other than those
that are =Grade 1 and either post-operative or stable on at least 2 consecutive MRI
scans.

10. Any condition which in the investigator's opinion makes the subject unsuitable for
study participation.

11. Lack of family or social support structure that would preclude continued participation
in the study.

PART B

Inclusion Criteria: Part B

2. Histologically confirmed WHO grade IV glioblastoma.

3. Unequivocal evidence of a first tumor recurrence with measurable disease, defined as 1
cm but no greater than 3 cm of enhancing tissue measured in 2 planes (axial, coronal,
or sagittal) after an initial treatment regimen (prior to enrollment on this study)
