About this study

Official title: A Phase 1b, Open Label, Multi-center, Dose Optimization and Dose Expansion Study to Assess the Safety and Efficacy of DFV890 in Adult Patients With Myeloid Diseases

Study CDFV890G12101 is an open-label, phase 1b, multicenter study with a randomized two-dose optimization part, and a dose expansion part consisting of three groups evaluating DFV890 in patients with myeloid diseases. The purpose of this study is to assess the safety, tolerability, pharmacokinetics, pharmacodynamics, efficacy and recommended dose for single agent DFV890 in patients with lower risk (LR: very low, low or intermediate risk) myelodysplastic syndromes (LR MDS), lower risk chronic myelomonocytic leukemia (LR CMML) and High-Risk Clonal Cytopenia of Undetermined Significance (HR CCUS).

Read the detailed description

This research study is to find out if study treatment DFV890 is safe and tolerable, and can help patients who were diagnosed with a myeloid disease such as: very low, low or intermediate risk myelodysplastic syndromes (MDS), very low, low or intermediate risk chronic myelomonocytic leukemia (CMML) and High-Risk Clonal Cytopenia of Undetermined Significance (HR CCUS). The study seeks to determine the optimal dose of DFV890 that is safe and efficacious in patients with myeloid disease. The effectiveness and safety/tolerability of the study treatment is not yet confirmed in this disease setting.

Eligible patients meeting all study entry requirements will be required to provide a sample from their bone marrow at screening and at select study timepoints. All enrolled patients will be dosed for a minimum of twenty-four weeks (6 cycles of treatment) unless they experience side effects related to the study treatment requiring dose interruption/discontinuation, worsening of the disease, and/or if treatment is discontinued at the discretion of the investigator or the patient.

Secondary outcomes (18)
  1. Reduction in red blood cell (RBC) / platelet transfusions from baseline for transfusion-dependent (TD) patients

    The number of red cell or platelet transfusions a patient receives over the course of study treatment will be compared to the patient's baseline transfusion requirements based on the transfusions received during the 16-weeks period prior to the start of study treatment.

    Measured: Baseline, 36 months

  2. Percentage of patients developing transfusion independence (TI) for ≥8 weeks, ≥12 weeks, ≥16 weeks or ≥24 weeks for TD patients

    The Myeloproliferative Neoplasm Symptom Assessment Form (MPN-SAF) Total Symptom Score (TTS) will be used for the assessment of symptom burden at baseline and monitoring symptom status during the course of treatment. MPN-SAF TSS includes the assessment of 10 symptoms (fatigue, concentration, early satiety, inactivity, night sweats, itching, bone pain, abdominal discomfort, weight loss, and fevers). Severity of each symptom is rated on a 0 (absent/as good as it can be) to 10 (worst-imaginable/as bad as it can be) scale. MPN-SAF TSS has a possible range of scores of 0 to 100 with 100 representing the highest level of symptom severity.

    Measured: Baseline, 12 months

  17. Maximum plasma concentration (Cmax) of DFV890

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 8 inclusion and 12 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: under way, not looking for participants, as of the sponsor's last update on 10 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 25 sites in United States, France, Germany, United Kingdom, Italy and 3 more countries. 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 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.

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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of Dose-limiting Toxicities (DLTs) (time frame: 28 days). The study lists 3 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 10 Sep 2026.
