A Phase 1/2 Study of VX15/2503 in Children, Adolescents, or Young Adults With Recurrent or Relapsed Solid Tumors

This phase I/II trial studies the side effects and best dose of anti-SEMA4D monoclonal
antibody VX15/2503 (VX15/2503) and to see how well it works in treating younger patients with
solid tumors that have come back after treatment, or do not respond to treatment. Monoclonal
antibodies, such as VX15/2503, may interfere with the ability of tumor cells to grow and
spread.

PRIMARY OBJECTIVES:

I. To estimate the maximum tolerated dose (MTD) and/or recommended Phase 2 dose of VX15/2503
administered as an intravenous infusion every 14 days to children with recurrent or
refractory solid tumors. (Part A) II. To define and describe the toxicities of VX15/2503
administered on this schedule. (Parts A-B) III. To characterize the pharmacokinetics of
VX15/2503 in children with recurrent or refractory cancer. (Parts A-B) IV. To preliminarily
define the antitumor activity of VX15/2503 for the treatment of relapsed or refractory
osteosarcoma. (Part B) V. To determine if VX15/2503 either improves the disease control rate
at 4 months in patients with recurrent measurable osteosarcoma or produces an objective
response rate in patients with relapsed or refractory osteosarcoma. (Part B)

SECONDARY OBJECTIVES:

I. To assess the pharmacodynamics of VX15/2503 through VX15/2503 saturation of T-lymphocytes.

II. To assess the immunogenicity of VX15/2503 in pediatric patients with recurrent or
refractory cancer.

EXPLORATORY OBJECTIVES:

I. To evaluate potential biomarkers of VX15/2503 sensitivity including SEMA4D, PlexinB1, and
other markers of immune cell infiltration in archival tumor tissues.

OUTLINE: This is a phase I, dose-escalation study followed by a phase II study.

Patients receive VX15/2503 intravenously (IV) over 60 minutes on days 1 and 15. Treatment
repeats every 28 days for 13 courses in the absence of disease progression or unacceptable
toxicity.

After completion of study treatment, patients are followed up periodically.

central nervous system (CNS) tumors; patients must have had histologic verification of

a wheelchair, will be considered ambulatory for the purpose of assessing the
performance score

- Patients must have fully recovered from the acute toxic effects of all prior
anti-cancer therapy and must meet the following minimum duration from prior
anti-cancer directed therapy prior to enrollment; if after the required timeframe, the
numerical eligibility criteria are met, e.g. blood count criteria, the patient is
considered to have recovered adequately

therapy, >= 14 days must have elapsed since last dose of corticosteroid

growth factor (e.g. pegfilgrastim) or 7 days for short-acting growth factor; for
agents that have known adverse events occurring beyond 7 days after
administration, this period must be extended beyond the time during which adverse
events are known to occur; the duration of this interval must be discussed with
the study chair and the study-assigned research coordinator

factors): >= 21 days after the completion of interleukins, interferon or
cytokines (other than hematopoietic growth factors)

cell infusion including donor lymphocyte infusion (DLI) or boost infusion:
>= 84 days after infusion and no evidence of graft versus host disease
(GVHD)

- Autologous stem cell infusion including boost infusion: >= 42 days

- Cellular Therapy: >= 42 days after the completion of any type of cellular therapy
(e.g. modified T cells, natural killer [NK] cells, dendritic cells, etc.)

- Radiation Therapy (XRT)/External Beam Irradiation including Protons: >= 14 days
after local XRT; >= 150 days after TBI, craniospinal XRT or if radiation to >=
50% of the pelvis; >= 42 days if other substantial bone marrow (BM) radiation

- Radiopharmaceutical therapy (e.g., radiolabeled antibody, 131I-MIBG): >= 42 days
