Phase 3: Open-Label Extension Period
Double-blind Period: Mitapivat 50 milligrams (mg) twice daily (BID) for 12 weeks.
Double-blind Period: Mitapivat 100 mg BID for 12 weeks.
Double-blind Period: Mitapivat-matching placebo for 12 weeks.
Participants who received mitapivat 50mg BID in the double-blind period may choose to receive mitapivat 50mg BID for 216 weeks after. Participants who received mitapivat 100mg BID in the double-blind period may choose to receive mitapivat 100 mg BID for 216 weeks after. Participants who received mitapivat-matching placebo in the double-blind period, may be randomized to receive either mitapivat 50 mg or 100 mg BID for 216 weeks after.
Double-blind Period: Mitapivat selected Phase 3 dose (50 mg or 100 mg BID) for 52 weeks.
Double-blind Period: Mitapivat-matching placebo selected Phase 3 dose (which can be either 50 mg or 100 mg BID based on the phase 2 results) for 52 weeks.
Participants may choose to receive the selected Phase 3 mitapivat dose (which can be either 50 mg or 100 mg BID based on the phase 2 results) for 216 weeks after the Double-blind Period.
