Group Intervention Description AG-881 (Group 1) AG-881 On Day 1 of Period 1, Group 1 participants will receive a single 50-milligram (mg) oral dose of lamotrigine at Hour 0. In Period 2, they will receive 50-mg oral doses of AG-881 once daily (QD) for 15 consecutive days (Days 1 to 15), with a single 50-mg oral dose of lamotrigine coadministered at Hour 0 on Day 14. AG-881 (Group 1) Lamotrigine On Day 1 of Period 1, Group 1 participants will receive a single 50-milligram (mg) oral dose of lamotrigine at Hour 0. In Period 2, they will receive 50-mg oral doses of AG-881 once daily (QD) for 15 consecutive days (Days 1 to 15), with a single 50-mg oral dose of lamotrigine coadministered at Hour 0 on Day 14. AG-881 (Group 2) AG-881 Following a safety and tolerability review of the data from at least 7 days of AG-881 dosing of Group 1 participants in Period 2, Group 2 participants will receive a single 50-mg oral dose of lamotrigine at Hour 0 in Period 1, and 50-mg oral doses of AG-881 QD for 15 consecutive days (Days 1 to 15), with a single 50-mg oral dose of lamotrigine coadministered at Hour 0 on Day 14 in Period 2. AG-881 (Group 2) Lamotrigine Following a safety and tolerability review of the data from at least 7 days of AG-881 dosing of Group 1 participants in Period 2, Group 2 participants will receive a single 50-mg oral dose of lamotrigine at Hour 0 in Period 1, and 50-mg oral doses of AG-881 QD for 15 consecutive days (Days 1 to 15), with a single 50-mg oral dose of lamotrigine coadministered at Hour 0 on Day 14 in Period 2. AG-881 (Group 3) AG-881 Following a safety and tolerability review of the data from Group 1 participants, and from at least 7 days of AG-881 dosing of Group 2 participants in Period 2, Group 3 participants will receive a single 50-mg oral dose of lamotrigine at Hour 0 in Period 1; and 50-mg oral doses of AG-881 QD for 15 consecutive days (Days 1 to 15) with a single 50-mg oral dose of lamotrigine coadministered at Hour 0 on Day 14 in Period 2. AG-881 (Group 3) Lamotrigine Following a safety and tolerability review of the data from Group 1 participants, and from at least 7 days of AG-881 dosing of Group 2 participants in Period 2, Group 3 participants will receive a single 50-mg oral dose of lamotrigine at Hour 0 in Period 1; and 50-mg oral doses of AG-881 QD for 15 consecutive days (Days 1 to 15) with a single 50-mg oral dose of lamotrigine coadministered at Hour 0 on Day 14 in Period 2.
