Researchers have taken the first steps towards the development of a gene therapy for multiple sclerosis — a treatment that boosted anti-inflammatory immune processes and reversed severe paralysis in mouse models of the disease. The University of Florida Health research team said it was optimistic that the therapy can work…

Specific gut bacteria may drive the progression of multiple sclerosis, according to a study showing that two bacterial species made the disease worse in a mouse model of MS. Researchers at the University of California, San Francisco also pinpointed a species — found in lower numbers in MS patients —…

Eli Lilly and Nektar Therapeutics have established a development and commercial agreement for the investigational T-cell stimulator therapy NKTR-358 for the treatment of autoimmune disorders, including multiple sclerosis. NKTR-358, discovered and initially developed by Nektar, has the potential to modulate immune system responses to re-establish an immune balance in patients with autoimmune disorders. The treatment targets the interleukin 2 receptor complex (IL-2R) that is expressed on the surface of a subset of immune cells called regulatory T-cells, or Tregs. NKTR-358 activity stimulates the proliferation of Tregs, which in turn will regulate the activity of other immune cells that are uncontrolled and are responsible for the underlying mechanisms of autoimmune disorders. "We look forward to working with Nektar to study this novel approach to treating a number of autoimmune conditions," Thomas F. Bumol, PhD, senior vice president of biotechnology and immunology research at Eli Lilly, said in a press release. "NKTR-358 is an exciting addition to our immunology portfolio and reinforces Lilly's commitment to sustain a flow of innovative medicines in our pipeline." Bumol added. Under the agreement, Lilly and Nektar will continue to jointly develop NKTR-358. Nektar will be responsible for completing the ongoing Phase 1 clinical study; and Phase 2 clinical development costs will be shared by the two companies, with Lilly covering 75 percent of the costs and Nektar the remaining 25 percent. Nektar will have the option to take part of the Phase 3 development of NKTR-358 on an indication-by-indication basis. "We are very pleased to enter into this collaboration with Lilly as they have strong expertise in immunology and a successful track record in bringing novel therapies to market," said Howard W. Robin, president and CEO of Nektar. "Importantly, this agreement enables the broad development of NKTR-358 in multiple autoimmune conditions in order to achieve its full potential as a first-in-class resolution therapeutic." Based on the announced agreement, Lilly will pay an initial amount of $150 million to Nektar, which will also be eligible to receive up to $250 million from additional development and regulatory milestones. In the future, Nektar may also receive royalties from the product depending on its investment in NKTR-358’s Phase 3 development and future product sales. Lilly will cover all costs of global marketing of NKTR-358, and Nektar will have an option to co-promote the drug in the United States.

Nektar Therapeutics has started a Phase 1 clinical trial of its biologic therapy NKTR-358 for inflammatory disorders and autoimmune diseases like multiple sclerosis. NKTR-358 is a first-in-class regulatory T-cell stimulator designed to correct the immune system dysfunction associated with these disorders. It targets regulatory T-cells, or Tregs. Other immunosuppressant therapies suppress the…

Short-chain dietary fatty acids, such as propionate, drive the production of regulatory immune T-cells in patients with multiple sclerosis (MS), while long-chain acids promote T-cells that are involved in inflammatory processes. Since the beneficial fatty acids are safe and can be obtained as over-the-counter dietary supplements, researchers suggest they could…

The VA Maryland Health Care System (VAMHCS) and the University of Maryland Fischell Department of Bioengineering are collaborating in a research initiative that aims to increase our understanding of multiple sclerosis (MS). The project is being led by Christopher M. Jewell, PhD, an assistant professor in bioengineering. Jewell will…

Immunization with molecules present specifically in myelin may be a new approach to treating multiple sclerosis (MS), according to a recent study that found that the mouse version of such molecules could stop ongoing disease processes in an MS mouse model. The study, “Targeting Non-classical Myelin Epitopes to Treat…

Damaging immune system defects seen in patients with multiple sclerosis (MS) can be repaired using a simple stem cell approach, according to a new study by researchers in China and the U.S. The study, “Umbilical Cord-Derived Mesenchymal Stem Cells Reversed The Suppressive Deficiency Of T Regulatory Cells From Peripheral Blood Of…

Immune cells, believed to drive autoimmunity, are selectively increased in the gut of patients with multiple sclerosis (MS), along with lower numbers of cells controlling inflammation, suggesting that immune processes in the gut impact MS disease mechanisms. The study, “The role of gut immunity in multiple sclerosis patients,”…

Editor’s note: The term B-cells is, in fact, a collective term for a group of cells having rather different properties. Some B-cells cells play a role in fighting invading pathogens or flawed cells, and can be wrongfully activated to target normal cells in autoimmune diseases. Regulatory B-cells (Bregs), instead act…

Researchers have found that changes in the composition of immune molecules — specifically, a shift to more anti-inflammatory cytokines and regulatory T-cells (Tregs) — likely account for the efficiency of alemtuzumab (Lemtrada) as a treatment for relapsing-remitting multiple sclerosis (RRMS). The study, titled “Alemtuzumab long-term immunologic effect: Treg suppressor function…

Researchers demonstrated a process that prevented an induced autoimmune disease from taking hold in the central nervous system of mice, and think it has the potential of being translated into a multiple sclerosis (MS) therapy. The study detailing the method and its promising results is entitled “Infusion of Sulfosuccinimidyl-4-[N-maleimidomethyl]cyclohexane-1-carboxylate-Conjugated MOG35–55-Coupled…

The National Multiple Sclerosis Society awarded a $700,000 research grant to Dr. Bonnie Dittel, a senior investigator at the BloodCenter of Wisconsin (BCW) and adjunct professor at the Medical College of Wisconsin. The grant will help Dr. Dittel advance her research into how specific immune cells in the body can…

Findings from two studies, recently published in the Journal of Clinical Investigation, indicate that high levels of salt alter the stability of the immune system and make it more susceptible to inflammation. The studies, which were led by Dr. David Hafler from Yale University and Dr. Dominik…
