Brief summary

The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics (PK), and preliminary food effect of ITU512 as well as the fetal hemoglobin (HbF)-inducing capacity of ITU512. This will be the first evaluation of the potential therapeutic effect of ITU512 in healthy participants and patients with sickle cell disease (SCD).

Detailed description

This is a global, randomized, Phase I/II study to assess the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary food effect of single-agent ITU512 in adult healthy participants, and safety, tolerability, PK, PD, and efficacy of ITU512 in adolescent and adult patients with sickle cell disease (SCD). The study consists of a first-in-human Phase I study (Part 1) in healthy participants, and a Phase II study (Part 2) in patients with SCD. Part 1 will comprise of Part 1A, Part 1B, and Part 1C. Part 2 will include Part 2A and 2B and may also include an extension part (Part 2C).

Interventions

DRUGITU512

ITU512 is an investigational, oral, low molecular weight (LMW) compound.

DRUGPlacebo

An inactive substance that looks like and is given the same way as ITU512. The effect(s) of ITU512 will be evaluated against the placebo. Placebos are designed as a control and to have no real effect.

Design outcomes

Primary

MeasureTime frameDescription
Part 1A, Part 1B, Part 1C: Incidence of AEs and SAEsUp to approximately 60 daysNumber of participants with adverse events (AEs) and serious adverse events (SAEs), including changes in vital signs, electrocardiograms (ECGs) and laboratory values qualifying and reported as AEs.
Part 1A, Part 1B , Part 1C: Dose discontinued due to AEUp to 30 daysNumber of participants with dose discontinuation due to AEs
Part 2A, Part 2B: Incidence of AEs and SAEsUp to 5 monthsNumber of participants with adverse events (AEs) and serious adverse events (SAEs), including changes in vital signs, electrocardiograms (ECGs) and laboratory values qualifying and reported as AEs.
Part 2A, Part 2B: Dose interruptions and reductionsUp to 4 monthsNumber of participants with dose interruptions or reductions of ITU512
Part 2A, Part 2B: Dose intensityUp to 4 monthsDose intensity of ITU512 is computed as the ratio of actual cumulative dose received and actual duration of exposure
Part 2B: Fetal hemoglobin (HbF)%Month 4Assessment of fetal hemoglobin expression by measuring fetal hemoglobin (HbF)% by high-performance liquid chromatography (HPLC) assay
