    Celiac.com 10/23/2019 - One approach to celiac disease that's been getting attention lately is the effort to develop ways to prevent the adverse immune reaction that is triggered by gluten that leads to gut damage in untreated celiacs. Several companies have tried that approach, including the promising, but now failed drug NexVax2. The idea is to train the immune system to become tolerant of gluten, kind of like the way allergists train the immune system to tolerate pollen, and thus, reduce or even eliminate allergic reactions.

    Data from a recent trial of new medical technology provides encouraging evidence that it is possible for people with celiac disease to achieve an immune tolerance to gluten, effectively reversing the autoimmune disease.

    The technology is a biodegradable nanoparticle containing gluten that teaches the immune system the antigen (allergen) is safe. The nanoparticle, called COUR nanoparticle, CNP-101, conceals the allergen in an innocuous cell covering, and convinces the immune system not to attack it.

    Celiac patients treated with CNP-101 were able to eat gluten with a substantial reduction in inflammation. The phase 2 results indicate that the treatment protects patients’ small intestine from gluten exposure, and point the way toward treatments that could allow celiac patients safely consume gluten in their diet.

    In addition to potentially reversing celiac disease, the technology, which uses a nanoparticle containing the antigen triggering the allergy or autoimmune disease, has the potential to treat myriad diseases and allergies, including multiple sclerosis, type 1 diabetes, peanut allergy, asthma, among others.

    The research team will present their findings on Oct. 22nd at the European Gastroenterology Week conference in Barcelona, Spain.

    The technology was devised in the lab of Stephen Miller, the Judy Gugenheim Research Professor of Microbiology and Immunology at Northwestern University Feinberg School of Medicine, who has refined it over decades.

    In addition to providing the first proof that the technology works in patients, the study shows that "we can encapsulate myelin into the nanoparticle to induce tolerance to that substance in multiple sclerosis models, or put a protein from pancreatic beta cells to induce tolerance to insulin in type 1 diabetes models,” said Miller. 

    The technology works by causing the immune system to see the allergen-loaded nanoparticle as innocuous debris, and to disregard it. Once ignored, the nanoparticle and its hidden antigen get eaten by a macrophage, kind of a garbageman that rids the body of cellular debris and pathogens.

    “The vacuum-cleaner cell presents the allergen or antigen to the immune system in a way that says, ‘No worries, this belongs here,'” Miller said. “The immune system then shuts down its attack on the allergen, and the immune system is reset to normal.”

    In the celiac trial, Miller's team loaded the nanoparticle with gliadin, the protein in gluten that triggers the adverse reaction in people with celiac disease.

    After a week of treatment, the patients consumed gluten for two weeks. Untreated celiac patients who ate gluten showed clear immune responses to gliadin and related damage to the small intestine. Meanwhile, celiac patients treated with CNP-101 showed 90% less immune-related inflammation than untreated patients. By preventing the inflammatory response, CNP-101 showed the ability to protect the gut from gluten-related damage.

    Most autoimmune diseases are currently treated with immune suppressants, which lessen symptoms, but degrade the immune response and carry the potential for toxic side-effects. CNP-101 does not work by suppressing the immune system, but by preventing the inflammatory response, and thus reversing the course of the autoimmune disease.

    Celiac disease a perfect target for the nanoparticle induced immune tolerance approach, because the triggers are well documented, and the disease has no other treatment than a gluten-free diet.

    CNP-101 has been granted Fast Track status by the U.S. Food and Drug Administration, and brought to patients in collaboration with Takeda Pharmaceuticals, which has acquired an exclusive global license to develop and commercialize this treatment for celiac disease.

    In addition to celiac disease, COUR is looking to develop treatments for peanut allergy and multiple sclerosis, and to expand their offerings to other autoimmune conditions, said John J. Puisis, president and chief executive officer of COUR.

    WOW!  I would LOVE for this to work!  I have a 'bucket list' of glutenous foods that I've been building in case I make it to 90 years old.  At that point I've decided I will indulge in all of these foods that I've been missing for so many years.   If I live to be 90, I figure I've already beaten the odds so why continue to deprive myself?  If the science in this article works ... I won't have to wait until I'm 90 and I won't have to eat all of those foods together!  I can eat them as a treat from time to time instead of in one sitting. ?

    Celiac.com 02/05/2018 - TIMP-GLIA, a new nanoparticle-based celiac disease treatment currently under development by Cour Pharmaceuticals, has received Fast Track Designation from the US Food and Drug Administration (FDA). Phase 1 studies to assess the safety and tolerability of TIMP-GLIA are currently underway in the United States.
    TIMP-GLIA works in part by encapsulating a component of wheat within a nanoparticle. The treatment has resulted in gluten tolerance in numerous animal models. By encasing components of gluten proteins in a nanoparticle, Cour is hoping that the gluten will remain unrecognized by the body's immune system, at least until immune tolerance can be generated through non-inflammatory antigen presentation.
    The FDA created the fast track process to speed development, review and commercialization of drugs that target serious conditions and fill an unmet medical need. Fast Track Designation puts Cour in a "prime position to advance an innovative new approach for the treatment of Celiac Disease," said John J. Puisis, CEO of Cour Pharmaceuticals.
    Cour is investigating TIMP-GLIA as part of an effort to reprogram the body's immune system so patients develop a tolerance to gluten as a non-threatening substance and ultimately to reduce or reverse celiac disease without the need for immune suppressing drugs. Cour's approach is designed to work by encasing a component of wheat in a nanoparticle, and introducing that particle into a celiac disease patient. If it works as designed, the gluten will remain unrecognized by the body's immune system until tolerance can be achieved through non-inflammatory antigen presentation.
    The phase 1 clinical trial for TIMP-GLIA study is being conducted at centers in the United States. The objective of the study is to assess the safety and tolerability of TIMP-GLIA when administered intravenously (IV) as a single dose at ascending dose levels and as a repeat dose in subjects with celiac disease.
    All in all, this is another of many bold and encouraging efforts to treat or cure celiac disease that have arisen in the last few years. Look for news of success or failure over then next few years.

    Celiac.com 05/25/2018 - People with celiac disease need to follow a lifelong gluten-free diet. However, once their guts have healed, they can still be sensitive to gluten. Sometimes even more sensitive than they were before they went gluten-free. Accidental ingestion of gluten can trigger symptoms in celiac patients, such as pain in the gut and diarrhea, and can also cause intestinal damage. 
    A new drug being developed by a company called Amgen eases the effects of people with celiac disease on a gluten-free diet. Researchers working on the drug have announced that their proof-of-concept study shows AMG 714, an anti-IL-15 monoclonal antibody, potentially protects celiac patients from inadvertent gluten exposure by blocking interleukin 15, an important mediator of celiac disease, and leads to fewer symptoms following gluten exposure.
    The drug is intended for people with celiac disease who are following a gluten-free diet, and is designed to protect against modest gluten contamination, not to permit consumption of large amounts of gluten, like bread or pasta.
    AMG 714 is not designed for celiac patients to eat gluten at will, but for small, incidental contamination. Francisco Leon, MD, PhD, study director and consultant for Amgen, says that their team is looking at AMG 714 “for its potential to protect against modest contamination, not deliberately eating large amounts of gluten, like bread or pasta.” 
    Amgen hopes that AMG 714 will help celiac patients on a gluten-free diet to experience fewer or less sever gluten-triggered events.
    Findings of the team’s first phase 2 study of a biologic immune modulator in celiac disease will be presented at the upcoming Digestive Disease Week 2018.

    Celiac.com 07/01/2019 - Drugmakers have pulled the plug on a phase II trial of Nexvax2, a promising drug for treating celiac disease. Pharmaceutical company ImmusanT, said that "results from an interim analysis revealed Nexvax2 did not provide statistically meaningful protection from gluten exposure for celiac disease patients when compared with placebo."
    That's a lot of fancy language to say that the drug simply didn't work. It did no better than a placebo. If there were any other way to spin it, the company would have spun it. They didn't. That basically means total failure.
    We've written about Nexvax2 over the years, and followed it through its development. It was promising enough to earn fast-track development status by the FDA.
    The company's press release reads as follows: 
    ImmusanT Discontinues Phase 2 Clinical Trial for Nexvax2® in Patients With Celiac Disease
    CAMBRIDGE, Mass. – June 25, 2019 – ImmusanT, Inc., a clinical stage company leveraging its Epitope-Specific Immuno-Therapy™ (ESIT™) platform to deliver first-in-class peptide-based immunomodulatory vaccine therapies to patients with autoimmune diseases, has discontinued the Phase 2 global study for its lead candidate, Nexvax2®, intended as a treatment for celiac disease.
    Similar to earlier Phase 1 results, Nexvax2 was found to be safe and generally well tolerated. There were no concerning safety issues identified during the study. ImmusanT will be actively investigating data gathered from the trial to further understand this outcome. The company will provide further information once available."
    So, to boil it down: The drug is safe and well tolerated, but it doesn't work any better than a placebo. The company will not pursue further testing.
    That's sad news and an ignoble end for a drug that held such high hopes. Few topics have generated as much excitement among celiac sufferers as the tantalizing possibility of a vaccine. Many eagerly hoped for success, while some wouldn't take it on a bet.
     It's unclear what this means for the technology behind Nexvax 2, as the underlying mechanics for this vaccine, Epitope-Specific Immuno-Therapy (ESIT), were to serve as the platform for future autoimmune treatments.
    Stay tuned for more on this and related stories.

    Celiac.com 09/09/2019 - A new oral drug for treating celiac disease could allow people with the disease to safely consume wheat, eliminating the need for a gluten-free diet. Capsules of ActoBiotics AG017 from ActoBio Therapeutics were recently granted new investigational drug (IND) status by the US Food and Drug Administration (FDA). 
    The drug contains a customized version of the bacterium Lacotococcus lactic, designed to express a gliadin peptide, coupled with an immunomodulating cytokine. The drug can be administered orally or topically, and so requires no injections.
    According to the company, ActoBiotics therapies promote antigen-specific immune tolerance that can prevent or reverse certain autoimmune and allergic diseases. AG017 is an antigen-specific celiac therapy with the potential to reverse gluten sensitivity that is aimed at the over 90% of celiac patients with the HLA-DQ2.5 genotype that responds to its immunomodulating cytokine.
    The drug will begin a Phase Ib/IIa study in patients with celiac disease in the US and Europe later in 2019.
    What do you think? Promising? Or likely more hype? Over the years, the celiac disease community has heard much about the promise of new drugs and treatments touting their ability to eliminate the need for a gluten-free diet, but nothing has come of it. We'll be keeping an eye on this drug to see how it pans out, so stay tuned.
