    IMU-856 Shows Promise as a Potential Treatment for Celiac Disease

    Reviewed and edited by a celiac disease expert.

    Positive phase 1b trial results offer clinical proof-of-concept for innovative gastrointestinal therapy drug IMU-856.

    Celiac.com 05/15/2023 - Biotechnology company Immunic, Inc., focuses on developing oral, small molecule therapies for chronic inflammatory and autoimmune diseases, including celiac disease.

    Celiac disease is an autoimmune disorder that affects approximately 1% of people globally. People with celiac disease have an abnormal immune response to gluten, a protein found in wheat, barley, and rye. This abnormal immune response damages the lining of the small intestine, leading to malabsorption and other serious complications.

    Celiac.com Sponsor (A12):
    The company recently announced positive results from the Part C portion of its Phase 1 clinical trial of IMU-856 in treating patients with celiac disease.

    The trial consisted of 36 patients with celiac disease who were randomized to receive placebo or one of two doses of IMU-856 (80 mg or 160 mg) for four weeks, followed by two weeks of gluten challenge. 

    The trial assessed the protection of gut architecture, reduction of gluten-induced intestinal damage, improvement of patients' symptoms related to gluten exposure, dose-dependent changes in biomarker responses, and enhancement of nutrient absorption.

    The trial results showed that patients treated with IMU-856 had a dose-dependent reduction in gluten-induced damage to their intestinal villi, the small, finger-like projections in the small intestine that play a key role in nutrient absorption. The results also showed that IMU-856 restored the absorption of essential nutrients, such as vitamin B12, for red blood cell formation and the functioning of the brain and nervous system. 

    Immunic believes the clinical evidence supports IMU-856's ability to re-establish proper gut cell renewal, which could prove useful in treating other gastrointestinal diseases. Patients treated with IMU-856 also saw improvement in disease-related symptoms such as bloating and tiredness, and the treatment was observed to be safe and well-tolerated.

    IMU-856's ability to re-establish proper gut cell renewal, observed in preclinical studies, translates into clinical benefits for patients with celiac disease.  Most importantly, the observed protection of intestinal villi from gluten-induced damage, independent of celiac-specific targeting immune mechanisms, seems to be unique among proposed therapeutic approaches, and may be applicable to other gastrointestinal diseases.

    Immunic is now preparing for clinical phase 2b testing of IMU-856 in ongoing active celiac disease, while also considering other potential clinical applications for this first-in-class and orally available molecule.

    The positive results from the Phase 1 clinical trial of IMU-856 offer some hope for the development of a new therapeutic approach to treating celiac disease and other gastrointestinal disorders. The trial's success represents a significant milestone in the effort to develop safe and effective treatments for patients with celiac disease, and other chronic inflammatory and autoimmune conditions.

    The company believes that this data set provides initial clinical proof-of-concept for a new therapeutic approach to gastrointestinal disorders by promoting the regeneration of bowel architecture.

    Now, the story of a promising new celiac drug treatment is a story familiar to many of us. So far, the story has always ended the same way: the promising drug fails in the end. Here's hoping this one ends more happily.

    Stay tuned for more on this and related stories.

    This is a very small study of very short duration... and it has not been replicated.  It is extremely premature to conclude that this drug is effective or safe.

    Even if it reduces symptoms, it does not treat the underlying pathological immune response.

    And whatever medication is finally developed and approved will probably be very expensive.

    It certainly will be in the US!

    The only thing I have seen that might work is retuximab. It eliminates B cells (which generate antibodies) from the body, allowing a fresh set to be generated from stem cells. There are several case reports of people having therapy for other conditions achieving improvement in their refractory coeliac disease from retuximab. However, it is not safe enough for routine treatment of coeliac disease but it does show that the possibility of immunotherapy exists.

    Do you have coeliac disease? The trial I saw showed no improvement.

    "reduction in gluten-induced damage to their intestinal villi"

    REDUCTION in damage. Those who got the drug and participated in the gluten challenge had LESS damage than those who got the placebo.  

    How much less?
    How much damage are those of us who have celiac supposed to accept as normal?
    What makes anyone think that damage to this critical part of the body is ever acceptable?

    How much of the small bowel was tested?
    How can we be certain that serious damage did not happen beyond the part of the small bowel that can be tested?

    What was the criteria for this measurement?

    Celiac nearly killed me before I was diagnosed. Please give me one reason why I would trust "LESS DAMAGE" as an acceptable measure compared to sticking with a 100% gluten free diet?

    I too am skeptical but glad research is being done attempting to find something that works. On the other hand, I have adapted my diet around my celiac and avoiding gluten is working for me. There are many foods that I miss but it is what it is.

    Working to reverse celiac disease. The idea is that hookworms were a natural part of gut biome balance in premodern times. Supposedly, the hookworms produce regulatory compounds that keep our immune systems healthy. In modern times we have largely eliminated hook worm infections and removed their regulatory benefit. Supposedly, this is a contributing factor to developing celiac disease. There are some scientific studies to support this but at this time it is still considered to be fringe therapy.

    Hookworms modify the immune systems' behavior to protect themselves in the gut. The argument is that in the history of the human species hookworms would have always been there, and as such would be a defacto component of the human immune system. Remove them and things can go haywire. That's the theory at least.

    I was about to undergo surgery for my ulcerative colitis to get a bag when I decided to try it. I bought hookworm larvae off the Internet and applied them to my skin. Within a month or two they resolved both my colitis and my celiac disease. Both are in full remission. I could bathe in gluten now if I wanted.

    The problem is my degree of success is an outlier. For most people it takes longer and the degree of success is less. For some people they get no results at all. Still, for others like myself it's been a miracle cure.

    Have you been clinically diagnosed with coeliac disease by blood serum antibody testing and intestinal biopsy? If so, have you had follow up testing since you applied the larvae to your skin? Did you develop a skin rash and have you had stool testing to establish that you are actually hosting hookworm?

    I've told this story before here, but I guess it bears repeating.

    For two years straight I was sick multiple times a day was catastrophic diarrhea. Towards the end I was hitting over 10x a day. I rarely left my apartment and was considering suicide. My GP wasn't any help. One day after getting sick after a sandwich I finally figured out the association. The diarrhea stopped the next day but the blood and mucus took a good six months+ to resolve. I also had colitis which complicated things but having the diarrhea stop was fantastic.

    I refused to take the biopsy because I wasn't willing to restart eating gluten. Whenever I was accidentally exposed I got terribly sick. Turned out my aunt and cousin were both celiacs with the same symptoms. That was good enough for me. This was in 2008.

    Probably 20x I was glutened btw 2008 and 2018 till when I started doing hookworms. Horrible, incapacitating reactions - accidental exposures with a good reason for being fooled each time. The colitis remained terrible. Lots of screaming. Turned out eating meat and nuts caused most of that.

    The rash for the hookworm entry is awesome. It looks horrible and blistery but heals without a scar. I've got a new shipment coming in in a couple of weeks and this time I'm going to try using some antihistamine cream. I'm never had a stool test but I did have a colony collapse once and saw a whole bunch of worm carcasses in my stool. I use 25 Necator americanus at a time.

    It's been a night and day difference since I've been on hookworms. No colitis unless I eat pistachios. I'm still lactose intolerant but other than that I have no food limitations. Bread with most meals.

    I've got a guy I email 2x a year and pay him by PayPal. An envelope with the larvae gets shipped out by courier.

    It bears repeating. Sometimes hookworms work for celiac disease, more often though gluten reactions are simply less. I lucked out. Crohn's and ulcerative colitis tend to do better with hookworms. Maybe it was because I had both celiac and colitis I did so well on them, who knows?

    Can Celiac Disease Impair Drug Therapy in Patients?
    Celiac.com 04/27/2017 - Celiac disease is associated with numerous chronic conditions, such as anemia and malabsorption of some critical vitamins. Changes in the gastrointestinal tract, rates of gastric emptying, and gastric pH are responsible for impaired vitamin and mineral absorption.
    Intestinal CYP3A4 levels may also be disrupted, which may have implications in first-pass metabolism for some drugs that are substrates for this drug metabolizing enzyme.
    This has led some researcher to investigate the potential impact of celiac disease on drug absorption. This would be of interest to pharmacists, since altered drug absorption can have pharmacokinetic consequences, along with the potential to impact overall drug therapy.
    A comprehensive review on this topic was published in 2...

    FDA Issues New Guidelines for Celiac Drug Trials
    Celiac.com 07/04/2022 - The Food and Drug Administration (FDA) has issued a set of new guidelines for companies doing celiac disease drug trials. The agency noted that the guidance is intended only to provide clarity regarding existing requirements, and should be viewed solely as recommendations, unless they mention specific regulations or laws.
    The FDA directs sponsors of trials for clinical drugs to ensure the following regarding celiac disease patients on a gluten-free diet:
    Trial population
    Patients should undergo diagnostic esophagogastroduodenoscopy, with multiple biopsies to confirm celiac diagnosis. The biopsies should include one or two samples of the duodenal bulb and at least four samples of the distal duodenum.
    To avoid inclusion of patients whose ...

    Celiac Disease Drug KAN-101 Gets FDA Fast Track
    Celiac.com 07/26/2022 - Previous drugs designed to induce tolerance to gliadin have met with failure. Will the latest effort fare any better? 
    In people with celiac disease, gliadin-specific T cells drive an adverse immune response to gluten peptides, which can cause symptoms, long-term gut damage, and other related conditions. Currently,  the only treatment for celiac disease is a gluten-free diet.
    A new drug, KAN-101, designed to treat celiac disease by inhibiting a key celiac disease biomarker, has received fast track status from the FDA ahead of Phase 2 Trials slated for the second half 2022. Designed by Anokion SA, a clinical-stage biotechnology company focused on treating autoimmune disease by restoring normal immune tolerance, KAN-101 has been found to be safe, well-to...

    Are Celiac Disease Drug Treatments Just a Pipe Dream?
    Celiac.com 09/21/2022 - The dream of creating a safe, effective drug that can help people with celiac disease to tolerate small amounts, or perhaps even large amounts, of gluten. Until its recent failure, 9 Meters' larazotide was the only celiac drug in Phase 3 clinical trials. The recent discontinuation of larazotide, based on disappointing interim results, highlights the unmet need for effective alternatives to a gluten-free diet for treating celiac disease. 
    Larazotide's failure also opens the doors for current and future Phase 1 and Phase 2 celiac therapies to be first-to-market. It also highlights the lack of a good lineup of potential new drugs. The reality is that, with the collapse of several once promising candidates, the bench for viable alternative celiac disease treatments ...
