Trial Information

A Pilot Study of Weekly EZN-2208 (PEGylated SN-38) in Combination With Bevacizumab in Refractory Solid Tumors


OBJECTIVES:

Primary

- Determine the modulation of HIF-1α protein (by ELISA) in patients with refractory solid
tumors after treatment with bevacizumab and
polyethyleneglycol-7-ethyl-10-hydroxycamptothecin (EZN-2208).

Secondary

- Determine the safety and tolerability of bevacizumab and EZN-2208 in these patients.

- Perform correlative studies (DCE-MRI and soluble markers) to assess changes in
angiogenesis in tumor tissue. (exploratory)

- Evaluate antitumor responses as determined by RECIST.

OUTLINE: Patients receive bevacizumab IV over 30-90 minutes on days 1 and 15 (day -7 of
course 1 only) and polyethyleneglycol-7-ethyl-10-hydroxycamptothecin IV over 60 minutes on
days 1, 8, and 15. Courses repeat every 28 days in the absence of disease progression or
unacceptable toxicity.

Patients undergo blood sample collection and tumor biopsies at baseline and during study for
HIF-1α protein expression and other correlative studies.

After completion of study therapy, patients are followed up for 28 days.

Inclusion Criteria


DISEASE CHARACTERISTICS:

- Histologically confirmed solid tumors

- Treated brain metastasis not requiring steroids and with no evidence of
progression or hemorrhage after treatment for ≥ 3 months, as ascertained by
clinical examination and brain imaging (MRI or CT scan), allowed

- Treatment for brain metastases may include whole-brain radiotherapy (WBRT),
radiosurgery (RS; Gamma Knife, LINAC, or equivalent), or a combination as
deemed appropriate by the treating physician

control, or abstinence) prior to, during, and for 3 months after completion of study

- Not pregnant or nursing

- No history of allergic reactions attributed to compounds of similar chemical or
biologic composition to polyethyleneglycol-7-ethyl-10-hydroxycamptothecin (EZN-2208)
or bevacizumab

abscess within the past 6 months

- No significant vascular disease (e.g., aortic aneurysm, requiring surgical repair or
recent peripheral arterial thrombosis) within the past 6 months

human antibodies

PRIOR CONCURRENT THERAPY:

- More than 4 weeks since prior chemotherapy or radiotherapy (6 weeks for nitrosoureas
or mitomycin C) and recovered

- There are no restrictions on prior therapy

- At least 2 weeks since receiving study drug as a participant in a phase 0 study
(or early phase I)

- No major surgical procedure, open biopsy, or significant traumatic injury within the
past 28 days, and no anticipation of need for major surgical procedures during the
course of the study

- No other concurrent investigational agents

- No other concurrent chemotherapy
