A Randomized, Placebo-controlled, Double Blind, Single Ascending and Multiple Ascending Dose Study to Assess the Safety, Pharmacokinetics and Pharmacodynamics of FT-4202 in Healthy Volunteers and Sickle Cell Disease Patients

About the study

FT-4202 is an oral small-molecule agonist of pyruvate kinase red blood cell isozyme (PKR)
being developed for the treatment of hemolytic anemias. This initial study will characterize
the safety, tolerability and the pharmacokinetics/pharmacodynamics (PK/PD) of a single
ascending dose and multiple ascending doses of FT-4202 in the context of Phase 1 studies in
healthy volunteers and sickle cell disease patients. The effects of food on the absorption of
FT-4202 will also be evaluated in healthy volunteers.
