In related news, here are updates from the 2024 MAKI trial. Researchers tested ZED1227, an oral drug that inhibits the enzyme transglutaminase‑2 (TG2), a key player in celiac-related gut damage.

The trial involved 58 participants on a daily 100 mg dose while consuming gluten. Biopsies before and after showed ZED1227 significantly prevented inflammation and intestinal damage. The drug effectively stopped T-cell and gene activity tied to the immune response seen in celiac disease. It was especially promising in individuals carrying the HLA‑DQ2 gene variant.

Dr. Markku Mäki (Tampere University) explained that gene-level analysis revealed ZED1227 prevented all known gluten-induced genetic changes linked to celiac response—showing it’s a strong candidate for treatment.

 

Weighing the Pros and Cons

Pros

For the new blood test:

  • No gluten challenge required – Less harm, less anxiety.
  • High accuracy – Strong sensitivity and specificity numbers.
  • Better diagnostic access – Especially helpful for those already gluten-free for years.

For ZED1227 (MAKI trial pill):

  • Protects the gut from accidental gluten – Offers peace of mind in social settings.
  • Eases emotional burden – Can improve quality of life on a strict gluten-free diet.
  • Targets the immune response – Works at the genetic and immune level, not just symptom relief.

 

Cons & Limitations

For the new blood test:

  • Still in research – Not yet available in clinics.
  • Small sample size – More studies needed for diverse populations.
  • Might not fully replace biopsy – In complex cases, tissue confirmation may still be needed.

For ZED1227:

  • Not FDA approved – More safety data and trials are needed.
  • Doesn’t allow full gluten consumption – It’s for protection, not permission.
  • Genetic variability – Most effective for those with HLA-DQ2; others may respond differently.

 

What You Can Do Now

Even as we wait for these options to reach the public, there are steps you can take now:

✔ Stay informed – Follow trusted sources from gluten.org
✔ Talk to your doctor – Especially if you’ve struggled to get diagnosed while gluten-free.
 ✔ Consider genetic testing – Knowing your HLA type (like DQ2 or DQ8) can help guide future decisions.
 ✔ Support awareness and advocacy – GIG continues to work for increased access, improved tools, and support for people at every stage of diagnosis and living gluten-free.
 ✔ Encourage clinical research participation – When appropriate, volunteer for trials that advance the science.
