A Phase I Study of VEGF Trap (NSC# 724770, IND# 100137) in Children With Refractory Solid Tumors


PRIMARY OBJECTIVES:

I. To estimate the maximum tolerated dose (MTD) or recommended phase II dose (RPTD) of
aflibercept administered intravenously every 14 days in children with relapsed or refractory
solid tumors.

II. To estimate the MTD or RPTD of aflibercept administered intravenously every 21 days in
these patients.

III. To define and describe the toxicities of intravenous aflibercept administered on a
14-day and 21-day schedule, respectively.

IV. To characterize the pharmacokinetics of intravenous aflibercept in these patients.

SECONDARY OBJECTIVES:

I. To define, preliminarily, the antitumor activity of intravenous aflibercept within the
confines of a phase I study.

OUTLINE: This is a multicenter study.

PART 1: Patients receive aflibercept IV over 1 hour on day 1. Treatment repeats every 14
days for 2 years in the absence of disease progression or unacceptable toxicity. Cohorts of
3-6 patients receive aflibercept until the maximum tolerated dose (MTD) is determined.

PART 2: Patients receive aflibercept as in part 1 at 150% of the MTD determined in part 1.
Treatment repeats every 21 days for 2 years in the absence of disease progression or
unacceptable toxicity.

Blood samples are collected prior to treatment on day 1 of courses 1, 2, and 5 or 6 for
pharmacokinetic studies.

After completion of study treatment, patients are followed for at least 30 days.


Inclusion Criteria:



- Histologically confirmed malignancy at original diagnosis or relapse (excluding
intrinsic brain stem tumors, optic pathway gliomas, or patients with pineal tumors
and elevations of serum alpha-fetoprotein of beta-HCG)

- Patients with recurrent or refractory solid tumors are eligible, including
primary CNS tumors or patients with known CNS metastases

- Current disease state must be one for which there is no known curative therapy or
therapy proven to prolong survival with an acceptable quality of life

- Measurable or evaluable disease

- No evidence of CNS hemorrhage on baseline MRI for patients with known CNS disease

- Neurologic deficits in patients with CNS tumors must have been relatively stable
for a minimum of 1 week prior to study entry

- Patients who are unable to walk because of paralysis, but who are up in a
wheelchair, will be considered ambulatory for the purpose of assessing the
performance score

- Patients with solid tumors without bone marrow involvement must meet the following
criteria:
