Second STOP After Pioglitazone Priming in CML Patients (PIO2STOP)

July 1, 2026 updated by: Philippe ROUSSELOT, Versailles Hospital

Combination Study of Pioglitazone and Tyrosine Kinase Inhibitors (TKIs) in Chronic Myeloid Leukemia Patients After Failure of a First TKIs Discontinuation Attempt in Order to Prepare a New Stop

Single-center study, prospective, phase II trial.

The study objectives are :

  • To assess safety and pharmacokinetics of the combination of PIO and TKI in CML subjects who experience a loss of MMR following a first TKI discontinuation.
  • To assess survival without loss of MMR over a 12 months period following a second TKI discontinuation in subjects who achieve or maintain < MR4.5 with the combination PIO and TKI administered for at least 6 months.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No
