Evaluation of Safety, Tolerability, PK & PD of Intravenous VX15/2503 in Patients With Advanced Solid Tumors - Full Text View

Purpose

The purpose of this study is to evaluate the safety and tolerability of IV administration of VX15/2503 in patients with advanced solid tumors. The escalation part of the study will determine the maximum tolerated dose (MTD).

Arms	Assigned Interventions
Experimental: VX15/2503 VX15/2503 monoclonal antibody at a concentration of 0.3 mg/kg - 20 mg/kg to be administered intravenously on a weekly dosing cycle.	Drug: VX15/2503 Dose escalation will begin at low doses and will gradually increase in each future cohort. The current trial design provides for 7 study cohorts with a 20 mg/kg expansion phase.

Detailed Description:

VX15/2503-01 is a dose-escalation, open label study to evaluate the safety and tolerability of IV administered VX15/2503 in patients with advanced solid tumors. This will be accomplished by using a dose escalation procedure starting at low doses of VX15/2503 and will continue based on predefined parameters until the maximum tolerated dose is identified.

The study drug, VX15/2503, is a monoclonal antibody that binds to the semaphorin 4D (SEMA4D; CD100) antigen. Semaphorins have been shown to play an important role in certain physiological processes such as vascular growth, tumor progression and immune cell regulation. Experimental evidence suggests that SEMA4D has two mechanisms of action that result in angiogenesis and tumor proliferation and invasion. Antibody neutralization of SEMA4D thus may represent a new therapeutic strategy for cancer treatment.
