NexImmune, Inc. (Nasdaq: NEXI), a clinical-stage biotechnology company developing a novel approach to immunotherapy designed to orchestrate a targeted immune response by directing the function of antigen-specific T cells, today announced a collaboration with the National Institute of Neurological Disorders and Stroke (NINDS), a division of the U.S. National Institutes of Health (NIH). The collaboration will focus on enriching and expanding virus-specific T cell populations and determining their activity against infected human cell lines. The goal of this collaboration is to develop adoptive cell therapies that may benefit patients afflicted with immunological disorders related to these viral infections. Initially, we will focus our efforts on studying Epstein-Barr virus (EBV) and Human T-cell Leukemia Virus, type 1 (HTLV-1).

“NexImmune is committed to developing novel therapies for the treatment of oncology, infectious disease and autoimmune disorders,” said Kristi Jones, Chief Executive Officer of NexImmune. “Compelling evidence exists that several autoimmune diseases are mediated by virally-infected cells. Current therapeutic approaches in these diseases broadly target cell populations that may or may not be expressly involved in the disease.  NexImmune’s AIM platform has the potential to selectively target and eliminate EBV-infected B cells in multiple sclerosis (MS), or HTLV-1-infected cells in HTLV-1 associated myelopathy (HAM), which may offer a unique benefit over current approaches. We will be working with the NINDS to evaluate EBV and HTLV-1 as therapeutic targets in the pathophysiology of neurological immune diseases. This important collaboration will enable us to leverage the AIM platform to develop potentially innovative antigen-specific therapies for these patients.”

“There is a clear causal relationship between HLTV-1 infection and HTLV-1 Associated Myelopathy and a potential relationship between EBV infection and MS,” stated David Hafler, M.D., FANA, and member of NexImmune’s Scientific Advisory Board. “This work will help advance our understanding of the role immune responses to viral infection play in different neuroimmunological diseases.”

About NexImmune

NexImmune is a clinical-stage biotechnology company developing a novel approach to immunotherapy designed to employ the body’s own T cells to generate a specific, potent, and durable immune response.

NexImmune’s lead programs, NEXI-001, NEXI-002 and NEXI-003, are in Phase 1/2 clinical trials for the treatment of relapsed AML after allogeneic stem cell transplantation, multiple myeloma refractory to 3 or more prior lines of therapy and HPV-related cancers, respectively. NexImmune is also developing AIM nanoparticle constructs and modalities for potential clinical evaluation in oncology and in disease areas outside of oncology, including autoimmune disorders and infectious disease.

The backbone of NexImmune’s approach is a proprietary Artificial Immune Modulation (AIM™) nanoparticle technology platform. The AIM technology enables NexImmune to construct nanoparticles that function as synthetic dendritic cells capable of directing a specific T cell-mediated immune response. AIM constructed nanoparticles employ natural biology to engage, activate and expand endogenous T cells in ways that combine anti-tumor attributes of antigen-specific precision, potency and long-term persistence with reduced potential for off-target toxicities.

About The National Institute of Neurological Disorders and Stroke and its Viral Immunology Section

Created by the U.S. Congress in 1950, the National Institute of Neurological Disorders and Stroke (NINDS) has occupied a central position in the world of neuroscience for over 70 years. The mission of NINDS is to reduce the burden of neurological disease—a burden borne by every age group, every segment of society, and people all over the world.

To accomplish this goal, the Institute supports and conducts basic, translational, and clinical research on the healthy and diseased nervous system; fosters the training of investigators in the basic and clinical neurosciences; and seeks better understanding, diagnosis, treatment, and prevention of neurological disorders.

The Viral Immunology Section studies the role of human viruses in the pathogenesis of chronic progressive neurologic disease. As part of its work, the laboratory is studying virological, immunological, and molecular mechanisms associated with the human T lymphotropic virus type-I associated myelopathy/tropical spastic paraparesis and the association of virus in multiple sclerosis.
