Mayo Clinic Says New Celiac Drug Reduces GI and Non-GI Symptoms

Celiac.com 07/28/2014 - One angle being tried by researchers to treat celiac disease involves oral peptides. These are orally administered drugs that would prevent an adverse gluten reaction in people with celiac disease who are following a gluten-free diet.

In a recent update from the Mayo clinic, Joseph Murray, MD, confirms that larazotide acetate, a first-in-class oral peptide, has ”met the study's primary end point of a reduction in GI symptoms.” Dr. Murray presented the results from the study as a late-breaking abstract at Digestive Disease Week 2014.

In a celiac disease reaction, the epithelial tight junctions that control paracellular permeability are compromised, and gut permeability increases. This is partly due to an inflammatory immune response to the entrance of gluten peptides into the intestinal lamina propria through these tight junctions.

Larazotide acetate prevents tight-junction opening and reduces gluten uptake, inhibiting gluten- and cytokine-induced intestinal permeability and inflammation in vivo.

This randomized, parallel, double-blind, placebo-controlled, multicenter trial was conducted at 74 sites in North America. The aim was to evaluate the effect of larazotide acetate on GI signs and symptoms in patients with celiac disease.

A waste of research time and money. We need a better solution than this band aid. Put the money to a more specific solution of counteracting the reaction to gluten in the intestine.

As I read it, this new drug does just that. What is your compliant, exactly?

Larazotide does not guard against the long term effect of gluten ingestion for celiac patients. It is designed only to reduce the symptoms that patients experience when they do ingest gluten. This drug is by no means the answer for celiac patients to be able to stop the gluten free diet and not suffer the negative long term effect gluten ingestion will have on the gut.

Does anyone know when larazotide acetate will be available for consumer use?

It's currently in early phase trials. If all goes well the company will apply for FDA approval. Still no time frame beyond early trial information. Stay tuned!

I would love to have something that would help take the worry out of cross contamination when eating out but I am hoping that the enzymes that are in clinical trials will do this. I worry about long term problems when we try to modify a normal response. Zonulin causes leaky gut in everyone - in those with CD the junctions are opened for a longer time. I heard Dr. Fasano say that Zonulin is there for a purpose and we don't fully understand it. Is it really safe to inhibit to inhibit this?

Thanks for letting me know. My back hurts all the time

I had a pillcam done two and a half months after I went gluten-free and it only showed gastropathy. three and a half months before the pillcam and endoscopy showed damage consistent with celiac. That damage was after a 10 or 11 week gluten challenge. prior to that I was gluten-free for a ...

It works much better for me but everyone is different. I have a physical job and sometimes get lower back pain. A hot shower and an Aleve will usually relieve it. It's worth your giving it a try.

Is Aleve better than ibuprofen? My back pain doesn't budge with 800 mg Motrin.

When I was diagnosed, I had only anemia. That is it. Later I found that I had osteoporosis as a result of untreated celiac disease. There are over 200 symptoms attributed to celiac disease. You may have many or NONE at all (called silent). After going gluten free within months my anemi...
