Descriptive Information
Brief Title  ICMJE Evaluation of Safety, Tolerability, PK & PD of Intravenous VX15/2503 in Patients With Advanced Solid Tumors
Official Title  ICMJE A Dose-Escalation Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Intravenous Infusion of VX15/2503 in Adult Patients With Advanced Solid Tumors
Brief Summary 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).
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.

Study Type  ICMJE Interventional
Study Phase  ICMJE Phase 1
Study Design  ICMJE Intervention Model: Single Group Assignment
