Study Endpoints
Primary Endpoints
Change From Baseline in Interferon-gamma Spot Forming Units (IFN-γ SFUs) in Human Leukocyte Antigens Density Quotient (HLA-DQ2.5-positive) Participants Based on Results of a Gliadin-Specific Enzyme-Linked Immunospot (ELISpot) Assay
Baseline (Day 15, or Day 1 in the absence of Day 15) to Week 3 (Day 20)

IFN-γ SFUs will be measured based on results of a gliadin-specific ELISpot assay using gluten-specific T cells which will be isolated from blood.

Secondary Endpoints
Percentage of Participants Experiencing at Least One Adverse Event (AE) and Adverse Events of Special Interest (AESIs)
From the first IV dose up to 30 days after last IV dose (Up to Week 28)
Change From Run-in (Visit 2) to Weeks 8, 14, and 20 in the Pre- to Post-gluten Challenge Change of the 3-day Average Nausea Severity Score as Measured in Celiac Disease Symptom Diary (CDSD)
Run-in (Visit 2), Weeks 8, 14, and 20
Change From Run-in (Visit 2) to Weeks 8,14, and 20 in the Pre- to Post-gluten Challenge Change in CDSD 3-day Peak Nausea Severity Score

Cohort 1, Group A: Placebo + Placebo + TAK-101 25 µg/kg GEEXPERIMENTALFollowing a single-day 3 gram (g) oral run-in gluten challenge, participants will receive TAK-101 placebo-matching intravenous (IV) infusion dose, once each on Days 1 and 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. A third IV infusion dose of TAK-101 25 microgram per kilogram (µg/kg) GE will be given 23 weeks after the second dose at approximately Week 24.
Cohort 1, Group B: TAK-101 25 µg/kg GE + Placebo + TAK-101 25 µg/kg GEEXPERIMENTALFollowing a single-day 3 g oral run-in gluten challenge, participants will receive TAK-101 25 µg/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. A third IV infusion dose of TAK-101 25 µg/kg GE will be given 23 weeks after the second dose at approximately Week 24.
Cohort 1, Group C: TAK-101 25 µg/kg GE + TAK-101 25 µg/kg GE + TAK-101 25 µg/kg GEEXPERIMENTALFollowing a single-day 3 g oral run-in gluten challenge, participants will receive TAK-101 25 µg/kg GE IV infusion, once each on Days 1 and 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. A third IV infusion dose of TAK-101 25 µg/kg GE will be given 23 weeks after the second dose at approximately Week 24.
Cohort 2, Group A: Placebo + Placebo + TAK-101 25 µg/kg GEEXPERIMENTALFollowing a single-day 3 g oral run-in gluten challenge, participants will receive TAK-101 placebo-matching IV infusion, once each on Days 1 and 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. A third IV infusion dose of TAK-101 25 µg/kg GE will be given 23 weeks after the second dose at approximately Week 24. Cohort 2 would start based on the results of Cohort 1.
Cohort 2, Group D: TAK-101 50 µg/kg GE + TAK-101 50 µg/kg GE+ TAK-101 50 µg/kg GEEXPERIMENTALFollowing a single-day 3 g oral run-in gluten challenge, participants will receive TAK-101 50 µg/kg GE IV infusion, once each on Days 1 and 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. A third IV infusion dose of TAK-101 50 µg/kg GE will be given 23 weeks after the second dose at approximately Week 24. Cohort 2 would start based on the results of Cohort 1.
Cohort 2, Group E: Placebo + Placebo + TAK-101 12.5 µg/kg GEEXPERIMENTALFollowing a single-day 3 g oral run-in gluten challenge, participants will receive TAK-101 placebo-matching IV infusion, once each on Days 1 and 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. A third IV infusion dose of TAK-101 12.5 µg/kg GE 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 Cohort 2 at the 50 µg/kg GE dose level.
Cohort 2, Group F: TAK-101 12.5 µg/kg GE + TAK-101 12.5 µg/kg GE + TAK-101 12.5 µg/kg GEEXPERIMENTALFollowing a single-day 3 g oral run-in gluten challenge, participants will receive TAK-101 12.5 µg/kg GE IV infusion, once each on Days 1 and 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. A third IV infusion dose of TAK-101 12.5 µg/kg GE will be given 23 weeks after the second dose at approximately Week 24. Cohort 2 would start based on the results of Cohort 1.
