A third IV infusion dose of TAK-101 1 mg/kg will be given 23 weeks after the second dose at approximately Week 24. Cohort 2 would start based on the results of Cohort 1. This group would be opened only if it is decided not to open the second cohort at the 4 mg/kg dose level i.e. if 4mg/kg Groups E and F are not opened.

Experimental: Cohort 2, Group E: TAK-101 1 mg/kg + Placebo + TAK-101 1 mg/kg - Following a single-day 3 g oral run-in gluten challenge, participants will receive TAK-101 1 mg/kg, IV infusion once on Day 1 followed by TAK-101 placebo-matching IV infusion, once on Day 8, followed by 12 g/day gluten for 3 days followed by 6 g/day gluten for 3 days starting at Week 2. Participants will then undergo single-day 3 g gluten challenges at Weeks 8, 14, and 20.

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.
2. Must be attempting to maintain a gluten-free diet (GFD) for =6 months.
3. Must be HLA-DQ2 and/or HLA-DQ8 positive during screening laboratory testing.

3. Has presence of inflammatory gastrointestinal disorders or autoimmune diseases, other than well-controlled autoimmune thyroid disease or well-controlled type 1 diabetes mellitus (defined as glycosylated hemoglobin <8% and no hospitalization in the last 12 months for hyper/hypoglycemia).
4. Has known or suspected refractory CeD or ulcerative jejunitis.
5. Has additional food allergies or intolerances that prevent participation in the food challenge.
6. Is receiving ongoing systemic immunosuppressant, systemic (oral or IV) corticosteroid treatment, or has received treatment with systemic immunosuppressants or corticosteroids in the 12 weeks before run-in gluten challenge.
