RPT904 (Q8W)EXPERIMENTALRPT904 every 8 weeks. The dose levels of RPT904 (150 mg, 300 mg, and 600 mg) within the Q8W cohort will be assigned based on participant weight and baseline total IgE level. RPT904 subcutaneous injection every 8 weeks with a loading dose at Week 2 (Part 1: 24 weeks; Part 2: 24 weeks); matching placebo at intervening visits to maintain blinding.
RPT904 (Q12W)EXPERIMENTALRPT904 every 12 weeks. The dose levels of RPT904 (150 mg, 300 mg, and 600 mg) will be assigned based on participant weight and baseline total IgE level. RPT904 subcutaneous injection every 12 weeks with a loading dose at Week 2 (Part 1: 24 weeks; Part 2: 24 weeks); matching placebo at intervening visits to maintain blinding.
PlaceboPLACEBO_COMPARATORPlacebo subcutaneous injection on schedules matching both the Q8W and Q12W arms in Part 1 (24 weeks); RPT904 every 8 or 12 weeks with a loading dose at Week 26 on schedules matching both the Q8W and Q12W arms Part 2 (24 weeks), with matching placebo at intervening visits to maintain blinding.
