Healthy Volunteers, Sickle Cell Disease
Conditions
Brief summary
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.
Detailed description
This is a first-in-human (FIH), Phase 1 study of FT-4202 that will characterize the safety, PK and PD of FT-4202 after a single dose and after repeated dosing first in healthy adult volunteers and then in adolescents or adults with sickle cell disease (SCD). Initially, a dose range of FT-4202 in single ascending dose (SAD) escalation cohorts will be explored in healthy subjects. Enrollment of healthy subjects into 2-week multiple ascending dose (MAD) escalation cohorts will be initiated once the safety and PK from at least two SAD cohorts is available to inform the doses for the 2-week MAD portion of the study. The MAD cohorts will then run in parallel to the single dose cohorts. A single dose cohort of healthy subjects is planned to understand food effects (FE) on the PK of FT-4202. After the SAD and FE studies in healthy subjects are completed, the safety, PK, and PD of a single dose of FT-4202 that was found to be safe in healthy subjects will then be evaluated in SCD subjects. Multiple dose studies in SCD subjects will then be initiated upon completion of MAD studies in healthy volunteers.
