PKD(Pyruvate Kinase Deficiency)가 있는 소아에서 정기적으로 수혈을 받고 5년을 연장한 대상자를 대상으로 Mitapivat의 유효성 및 안전성을 평가하기 위한 연구 (ACTIVATE-KidsT)
정기적으로 수혈되는 피루브산 키나제 결핍이 있는 소아 피험자를 대상으로 미타피바트의 효능 및 안전성을 평가하기 위한 3상, 다기관, 무작위, 이중 맹검, 위약 대조 연구, 이후 5년의 공개 라벨 연장 기간
ACTIVATE-KidsT (AG348-C-022) is a multicenter study designed to evaluate the efficacy and safety of treatment with mitapivat compared with placebo in pediatric participants with pyruvate kinase deficiency (PK deficiency) who are regularly receiving blood transfusions. Participants will be randomized 2:1 to receive either mitapivat or matching placebo. Randomization will be stratified by age (1 to < 6 years, 6 to < 12 years, 12 to < 18 years) and splenectomy status. Participants will be dosed by age and weight during a double-blind period consisting of an 8-week dose titration period followed by a 24-week fixed-dose period. Participants who complete the double-blind period will be eligible to receive mitapivat in the open-label extension (OLE) period.

실험적: Mitapivat
For participants randomized to receive mitapivat, dosing occurs orally twice daily (BID), and is based on age and weight. Dosing is optimized through 2 potential sequential increases in dose levels (1-5 mg, 4-20 mg and 10-50 mg) at Week 4 and Week 8, and aims to achieve the adult-equivalent exposure at 5, 20, and 50 mg. Following titration, participants remain on their individually optimized dose during the remainder of the Double-blind (DB) Period for 24 weeks. After the DB period, participants will enter an Open-label Extension (OLE) Period. To preserve blinding of treatment allocation, participants will continue mitapivat at their optimized dose and undergo mock titration with placebo for 8 weeks. At the conclusion of 8 weeks, participants may continue receiving mitapivat in the OLE Period for up to 262 weeks (including up to 2 weeks of dose taper). |

위약 비교기: Placebo
For participants randomized to receive matched placebo, dosing is identical to that described above for mitapivat. Following the initial dose titration period, participants remain on their individually optimized dose during the remainder of the DB period for 32 weeks. After the DB period, participants will enter an OLE period. To preserve blinding of treatment allocation, participants will continue placebo at their optimized dose and undergo mitapivat dose optimization through 2 potential sequential increases in dose levels (1-5 mg, 4-20 mg and 10-50 mg) at Week 4 and Week 8 of the OLE Period, and aims to achieve the adult-equivalent exposure at 5, 20, and 50 mg. At the conclusion of 8 weeks, participants may continue receiving mitapivat in the OLE Period for up to 262 weeks (including up to 2 weeks of dose taper). |

Change from Baseline in Pediatric Quality of Life (PedsQL) Multidimensional Fatigue Scale
기간: Baseline up to Week 292
|
The PedsQL multidimensional fatigue scale yields a total score from age-appropriate validated questionnaire that asks for perceived fatigue within the domains of 'General', 'Sleep/Rest' and 'Cognitive'. Each domain consists of 6 questions that are rated from 0 to 4 (therefore total score can range from 0 to 72). A higher total score indicates greater fatigue (i.e., worse outcome). |
Baseline up to Week 292

|
Change from Baseline in PedsQL Generic Core Scale (GCS)
기간: Baseline up to Week 292
|
PedsQL GCS is designed to measure health-related quality of life in pediatric participants and adolescents (2 to 18 years of age). It encompasses 4 dimensions of functioning (physical [8 items], emotional [5 items], social [5 items], school [3 items]). Age groups: Toddler (2-4 years), Young pediatric (5-7 years), Pediatric (8-12 years), and Teens (13-17 years). Depending on the participant's age, the questionnaire may be completed by parent/caregiver as appropriate. For the Toddler group, the PedsQL GCS consist of 21 items, using a 5-point Likert scale (0 to 4); for all other groups, the PedsQL GCS consist of 23 items, with a 3-point Likert scale (0, 2, 4) for the young pediatric, and a 5-point Likert scale for the pediatric and teens groups. Scores are transformed on a scale from 0 to 100 where 0=100, 1=75, 2=50, 3=25, and 4=0. Higher scores indicate improved quality of life. |
