RTL1000 is a new agent that has not been previously tested in humans. It is thought that RTL may specifically control the abnormal immune response or attack against the insulation on the nerves that occurs in multiple sclerosis.
The purpose of this study is to evaluate the possible side effects of a single intravenous dose of RTL1000 in subjects with multiple sclerosis. Some subjects will also be asked to participate in one or both of two substudies, one to test blood samples to see how the body's immune system responds after administration of RTL1000, and the other to test blood samples to see how the body absorbs and eliminates the RTL1000.
This is a double-blind, placebo-controlled treatment protocol with up to six treatment cohorts, each of which receives a single intravenous infusion of an escalating dose of RTL1000. Each dosing group will have six subjects: two who will receive a single dose of placebo and four who will receive a single dose of RTL1000. Subjects are observed in the hospital during the infusion and for 24 hours afterward, and are then followed weekly for 28 days and at 1 and 2 months post-infusion to evaluate safety parameters.
Objectives of the study are to evaluate the safety profile of a single dose of RTL1000 administered by intravenous infusion, to evaluate the pharmacokinetic profile of RTL1000 in a subset of subjects, and to evaluate the feasibility of assessing immunologic parameters in a subset of subjects.
Endpoints include vital signs, electrocardiogram and physical examination results, adverse events, and serious adverse events and safety laboratory parameters (e.g., clinical chemistries and hematology values). Disease parameters, such as neurological findings, expanded disability status scale (EDSS), 25-ft timed walk, 9-hole peg test, and magnetic resonance imaging (MRI) will be measured to ensure that study treatment does not make disease worse. Subjects will also be tested at the beginning and end of the study for antibodies to the drug and its components.

A cell surface receptor involved in regulation of cell growth and differentiation. It is specific for EPIDERMAL GROWTH FACTOR and EGF related peptides including TRANSFORMING GROWTH FACTOR ALPHA, amphiregulin, and heparin-binding EGF-like growth factor. The binding of ligand to the receptor causes activation of its intrinsic tyrosine kinase activity and rapid internalization of the receptor-ligand complex into the cell.
A secreted member of the TNF receptor superfamily that negatively regulates osteoclastogenesis. It is a soluble decoy receptor of RANK LIGAND that inhibits both CELL DIFFERENTIATION and function of OSTEOCLASTS by inhibiting the interaction between RANK LIGAND and RECEPTOR ACTIVATOR OF NUCLEAR FACTOR-KAPPA B.
A tumor necrosis factor receptor subtype found in a variety of tissues and on activated LYMPHOCYTES. It has specificity for FAS LIGAND and plays a role in regulation of peripheral immune responses and APOPTOSIS. Multiple isoforms of the protein exist due to multiple ALTERNATIVE SPLICING. The activated receptor signals via a conserved death domain that associates with specific TNF RECEPTOR-ASSOCIATED FACTORS in the CYTOPLASM.
A cell surface protein-tyrosine kinase receptor that is found to be overexpressed in a significant number of adenocarcinomas. It has extensive homology to and can heterodimerize with the EGF receptor (RECEPTOR, EPIDERMAL GROWTH FACTOR), the erbB-3 receptor (RECEPTOR, ERBB-3) and the erbB-4 receptor. Activation of the erbB-2 receptor occurs during heterodimer formation with a ligand-bound erbB receptor family members.
A ligand that binds to but fails to activate the INTERLEUKIN 1 RECEPTOR. It plays an inhibitory role in the regulation of INFLAMMATION and FEVER. Several isoforms of the protein exist due to multiple ALTERNATIVE SPLICING of its mRNA.
