Feasibility of the LUM Imaging System for Detection of Cancer to the Brain

The primary objective of this feasibility study is to identify an effective dose of LUM015
for imaging low grade gliomas, glioblastomas and cancer metastases to the brain. The optimal
dose will be used for future studies. Both normal brain tissue and tumor tissue will be
imaged and analyzed using the LUM Imaging device. The LUM Imaging System is a combination
product consisting of the LUM Imaging Device and the imaging agent LUM015.

Subjects with a possible diagnosis of low grade glioma, glioblastoma and metastases to the
brain, and scheduled for surgical resection, will be screened, recruited. On day of scheduled
surgery, the subject will be administered with LUM015 4 ± 2 hours prior to using LUM Imaging
System during surgery. LUM015 will be administered via peripheral intravenous (IV) injection
as a single dose between 1.0 - 3.0 mg/kg.

Before the tumor mass is resected, the LUM Imaging Device will be used to scan images of
distinct areas of grossly normal appearing brain tissue and, separately, images of distinct
areas of grossly appearing tumor. Following tumor mass resection, the tumor bed is scanned to
record in vivo images. The resected tissue will also be imaged ex vivo.

All subjects will continue to be monitored until hospital discharge and followed through
their first standard of care post-surgical visit. Subjects with adverse events that are
determined to be possibly related to the investigational product will continue to be followed
until resolution or stabilization of the adverse event.

Inclusion Criteria:

- Has radiologic imaging with a presumed diagnosis of low grade gliomas, glioblastoma/
grade III glioma or cancer metastases to the brain and must be scheduled for surgical
resection

- Male or female subjects 18 years of age or older

- Subjects must have normal liver, kidney, and bone marrow function as defined below:

- Leukocytes > 3,000/mcL

- Platelets > 100,000/mcL

- total bilirubin within normal institutional limits

- AST (SGOT)/ALT (SGPT) < 2.5 X institutional upper limit of normal

- Creatinine ≤ 1.5 mg/dL or creatinine clearance > 60 mL/min/1.73 m2 for subjects
with creatinine levels above institutional normal.

- Women of child-bearing potential must agree to use adequate contraception (hormonal or
barrier method of birth control, abstinence) starting the day entering the study, and
for 60 days after injection of the imaging agent

- Subjects with ECOG performance status of 0 or 1

Exclusion Criteria:

- Subjects previously treated with systemic therapies to treat the cancer to be removed
during this clinical investigation, such as neo-adjuvant chemotherapy or hormonal
therapy.

- Subjects with a known current condition of substance addiction.

- Subjects who have taken an investigational drug within 30 days of enrollment or those
who have not recovered from adverse events due to pharmaceutical or diagnostic agents.

- Subjects with uncontrolled hypertension defined as persistent systolic blood pressure
> 180 mm Hg, or diastolic blood pressure > 110 mm Hg; those subjects with known HTN
should be stable within these ranges while under pharmaceutical therapy.

- History of allergic reaction attributed to drugs containing polyethylene glycol (PEG).

- History of allergic reaction to any oral or intravenous contrast agents.

- Uncontrolled intercurrent illness including, but not limited to ongoing or active
infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac
arrhythmia, COPD or asthma requiring hospitalization within the past 12 months, or
psychiatric illness/social situations that would limit compliance with study
requirements.

- Subjects who are pregnant or nursing.

- Subjects who are sexually active and not willing/able to use medically acceptable
forms of contraception upon entering the study.

- HIV-positive individuals on combination antiretroviral therapy are ineligible because
of the potential for pharmacokinetic interactions with LUM015.
