About this study

Official title: A Phase I/II Clinical Study to Investigate the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Efficacy of ITU512 in Healthy Participants and Patients With Sickle Cell Disease

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).

Read the 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).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ITU512Drug

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

  • PlaceboDrug

    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.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing ITU512 in people with Sickle Cell Disease, run by Novartis Pharmaceuticals at 14 sites in 3 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 27 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 14 sites in United States, Brazil, Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Novartis Pharmaceuticals (1-888-669-6682, novartis.email@novartis.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Part 1A, Part 1B, Part 1C: Incidence of AEs and SAEs (time frame: Up to approximately 60 days). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Oct 2026.
