About
The main aim of the study is to assess if TAK-101 can reduce gluten related symptoms and immune activation in adult participants with celiac disease (CeD) on a gluten-free diet (GFD).
Participants will receive TAK-101 and/or placebo through the vein on Day 1 and Day 8. All participants will receive active treatment at Week 24.
Full description
The drug being tested in this study is called TAK-101. TAK-101 is being tested to treat people who have celiac disease. The study has two cohorts planned. The first cohort has 1 dose level and the second cohort may include 1 or 2 dose levels, depending on safety, tolerability, and activity observed in the first cohort. Dosing in the second cohort will be based on data from the initial cohort.
The study will enrol approximately 108 patients (18 per arm). In the first cohort, approximately 45 participants will be randomly assigned in 1:2:2 ratio in one of the three arm groups which will remain undisclosed to the participant and study doctor during the study (unless there is an urgent medical need). Eligible participants in Cohort 1 will receive:
After the review of Cohort 1 safety data, a decision will be made to either stop the study or continue the study by the sponsor safety management team (SMT), based on recommendations from independent data monitoring committee (IDMC). If it is deemed appropriate to enroll both the TAK-101 4 mg/kg and 1 mg/kg dose level, approximately 63 participants may be randomly assigned in 1:2:2:2 ratio in Cohort 2 to receive:
In Cohort 2 if the 1 mg/kg treatment arm is not needed, Cohort 2 will consist of 45 participants in total, being randomized in a 1:2:2 ratio to 1 of the 3 treatment groups (Groups D, E, F) listed above.
If it is decided not to open the second cohort at the 4 mg/kg dose level and if 1 mg/kg dose is recommended to be tested by the IDMC, approximately 45 participants will be randomly assigned in 1:2:2 ratio to receive:
This trial will be conducted in United States and Canada. The overall time to participate in this study is approximately 24 weeks. Participants will make multiple visits to the clinic, and will be contacted by telephone OR plus a final visit after receiving their last dose of study drug for a follow-up assessment.

Inclusion criteria
Biopsy-confirmed CeD that is well-controlled, defined as mild or with no ongoing signs or symptoms felt to be related to active CeD and with immunoglobulin A (IgA) tissue transglutaminase (tTG) <2 × upper limit of normal (ULN) and IgG deamidated gliadin peptide (DGP) <3 × ULN.
Note: Participants may be retested for IgA tTG and IgG DGP to meet eligibility criteria at the discretion of the investigator. Intermittent symptoms would not exclude participants from participation as long as symptoms are generally well controlled in the opinion of the investigator, and as long as symptoms are back to baseline for 2 weeks before the run-in gluten challenge.
Must be attempting to maintain a gluten-free diet (GFD) for ≥6 months.
Must be HLA-DQ2 and/or HLA-DQ8 positive during screening laboratory testing.
