T-Regulatory Cells in ALS

2019-08-19 19:46:45 | BioPortfolio


This study is a randomized, placebo-controlled, phase 2a trial to study the biological activity, safety, and tolerability of regulatory T Lymphocytes (Tregs) taken and expanded outside of the body and returned back to the same person whose Treg were removed, given back by IV (intravenously) and in combination with low-dose IL-2 in people with Amyotrophic Lateral Sclerosis (ALS).


Based on data collected in a previous study with a small group of patients, evidence was found to show that interfering with the immune system using Treg cells slowed ALS disease progression. It is known that Treg cell numbers and function are reduced in patients with ALS and in some patients with lower Treg cells, they have a more marked rapid progression of their ALS. For this study, there are two sites (in Houston, TX and Boston, MA) in which Tregs will be taken from participants, increased or expanded outside the body, and then re-administered back to the participants from which the Tregs came.

This study has two parts:

1. the first period is a 6-month phase 2a, 2-center, randomized, placebo-controlled clinical trial studying the biological activity, safety, and tolerability of the increased / expanded Tregs administered intravenously (IV) with subcutaneous low-dose Interleukin-2 (IL-2) in 12 adults with ALS. IL2 helps regulate the immune system's white blood cells.

2. The second period is a 6-month open-label extension in which all participants will receive their own expanded Treg cells administered intravenously in combination with subcutaneous low-dose IL-2.

This study is studying whether the enhancement of Treg numbers and function will slow disease progression.

In the first study of Tregs, we completed a single-center, open-label phase I study of Tregs from people with ALS. Tregs were increased outside the body and returned back to the individual Treg owners in multiple doses every 2 to 4 weeks. This early study provided evidence in a small group of patients that treatment with autologous Tregs may be effective in slowing ALS progression.

Medical and Biotech [MESH] Definitions

An interleukin receptor subtype found on both hematopoietic and non-hematopoietic cells. It is a membrane-bound heterodimer that contains the INTERLEUKIN-4 RECEPTOR ALPHA SUBUNIT and the INTERLEUKIN-13 RECEPTOR ALPHA1 SUBUNIT. Although commonly referred to as the interleukin-4 type-II receptor this receptor has specificity for both INTERLEUKIN-4 and INTERLEUKIN-13

Lymphocytes that show specificity for autologous tumor cells. Ex vivo isolation and culturing of TIL with interleukin-2, followed by reinfusion into the patient, is one form of adoptive immunotherapy of cancer.

High affinity receptors for INTERLEUKIN-3. They are found on early HEMATOPOIETIC PROGENITOR CELLS; progenitors of MYELOID CELLS; EOSINOPHILS; and BASOPHILS. Interleukin-3 receptors are formed by the dimerization of the INTERLEUKIN-3 RECEPTOR ALPHA SUBUNIT and the CYTOKINE RECEPTOR COMMON BETA SUBUNIT.

An interleukin-4 receptor subtype that is found predominantly on hematopoietic cells. It is a heterodimer of the INTERLEUKIN-4 RECEPTOR ALPHA SUBUNIT and the INTERLEUKIN RECEPTOR COMMON GAMMA-CHAIN.

A member of the INTERLEUKIN-1 protein family involved in the maturation of TH2 CELLS and the activation of MAST CELLS; BASOPHILS; EOSINOPHILS and NK CELLS. It is also produced by ENDOTHELIAL CELLS; EPITHELIAL CELLS and FIBROBLASTS; where it can function as an alarmin to modulate immune and inflammatory responses to tissue damage.
