Brief Summary:
This clinical trial is a Phase 2/3 study that will evaluate the efficacy and safety of FT-4202 and test how well FT-4202 works compared to placebo to improve the amount of hemoglobin in the blood and to reduce the number of vaso-occlusive crises (times when the blood vessels become blocked and cause pain).

Condition or disease Intervention/treatment Phase
Sickle Cell Disease Drug: FT-4202 Tablets Drug: Placebo Tablets Phase 2 Phase 3

Detailed Description:
FT-4202 is an oral small-molecule activator of pyruvate kinase red blood cell isozyme (PKR) being developed for the treatment of hemolytic anemias. This study is a randomized, placebo-controlled, double-blind, multicenter Phase 2/3 study of patients age 12 to 65 years (inclusive), with sickle cell disease. There are two planned interim analyses in this study design. Initially, patients will be randomized at 1:1:1 to one of two dose levels of FT-4202 or placebo. At the first interim analysis, one of the two FT-4202 dose levels will be selected for the Phase 3 portion of the study, in which patients will be randomized at 1:1 to the selected FT-4202 dose or placebo. Efficacy on hemoglobin will be evaluated at the second interim analysis, and then will be tested along with evaluation of efficacy on vaso-occlusive crises at the final analysis. Following completion of 52 weeks of double-blind treatment, patients may enter a 52-week FT-4202 open-label extension period.

Primary Outcome Measures :
  1. Hemoglobin response rate at Week 24 (increase of > 1 g/dL [> 10 g/L] from baseline) during the blinded treatment period [ Time Frame: 24 Weeks ]
  2. Annualized vaso-occlusive crisis rate during the 52-week blinded treatment period based on adjudicated vaso-occlusive crisis review [ Time Frame: 52 Weeks ]

Secondary Outcome Measures :
  1. Change from baseline in hemoglobin at Week 24 during the blinded treatment period [ Time Frame: 24 Weeks ]
  2. Change in Sickle Cell Disease related clinical laboratory measurements from baseline at Week 24 during the blinded treatment period [ Time Frame: 24 Weeks ]
    • % reticulocytes,
    • Unconjugated bilirubin
    • Lactate dehydrogenase (LDH)

  3. Time to first vaso-occlusive during the blinded treatment period [ Time Frame: 52 Weeks ]
  4. Change from baseline in Patient-Reported Outcome Measurement Information System (PROMIS) Fatigue Scale at Week 24 during the blinded treatment period [ Time Frame: 24 Weeks ]
    Adult patients (ages 18 to 65) will complete the PROMIS® Item Bank v.1.0 - Fatigue - Short Form 7a. Adolescent patients (ages 12 to 17) will complete the PROMIS® Item Bank v2.0 - Fatigue - Short Form 10a. Responses are graded on a score of 1 to 5 with a higher score indicating a worse outcome.
