About this study

Official title: Phase 1/2 Multicenter, Open-Label Study of CTX-712 in Patients With Relapsed/Refractory Acute Myeloid Leukemia and Higher Risk Myelodysplastic Syndromes

The goal of this phase 1/2 multicenter, open-label, single-arm dose escalation and expansion study is to assess the safety, tolerability, pharmacokinetic and pharmacodynamic profile of CTX-712 in patients with relapsed/refractory (R/R) acute myeloid leukemia (AML) and higher risk myelodysplastic syndromes (HR-MDS), or MDS/MPN (including CMML).

The phase 1 part of the study consists of sequential standard 3 + 3 dose escalation, where patients will receive ascending doses of CTX-712 to determine the recommended phase 2 dose (RP2D) for further clinical development. This is followed by initial expansion cohorts in AML and/or HR-MDS where patients will be treated with CTX-712 at the RP2D to gain further confidence in the selected dose level. Additional expansion cohorts may be initiated if considered necessary. After RP2D is determined, Drug-Drug-Interaction cohorts will be started.

The phase 2 part of the study will commence after the RP2D has been identified and confirmed and will evaluate therapeutic activity in R/R AML or R/R HR-MDS, in addition to confirmation of the safety profile.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Phase 1: Frequency of treatment-emergent adverse events (TEAEs) and serious adverse events (SAEs) related to CTX-712.

    Measured: Adverse events are collected from time of informed consent through 28 days after last dose of CTX-712.

  2. Phase 1: The maximum tolerated dose MTD.

    MTD is the dose producing <33% of dose-limiting toxicities.

    Measured: Dose-limiting toxicities are collected during the first treatment cycle (28 days).

  3. Phase 2: Complete remission rate, defined as the proportion of patients who achieve complete remission.

    Measured: Measured from date of first dose to 28 days after last dose of CTX-712.

Secondary outcomes (12)
  1. Phase 1 and 2: Objective response rate, defined as the proportion of patients achieving a response.

    For AML: CR, CRi, PR, MLFS. For MDS: CR, PR, mCR, HI.

    Measured: Measured from date of first dose to 28 days after last dose of CTX-712.

  2. Phase 1 and 2: Duration of response.

    Measured: Measure from documentation of tumor response to disease progression or death from any cause, whichever occurs first, assessed up to 24 months.

  3. Phase 1 and 2: Progression-free survival.

    Measured: Measured from the date of initiating study treatment to the date of disease progression or death from any cause, whichever occurs first, assessed up to 24 months.

  4. Phase 1 and 2: Overall survival.

    Measured: Measured from the date of initiating study treatment to the date of death from any cause, assessed up to 36 months.

  5. Phase 1 and 2: Proportion of patients who transition to hematopoietic stem cell transplantation (HSCT).

    Measured: Measured from the date of the last administration of CTX-712 until HSCT, or one year from the date of the start of administration of CTX-712.

  6. Phase 1: Maximum observed plasma concentration (Cmax) of CTX-712. Plasma samples for PK analyses will be collected at predetermined time points and analyzed.

    Measured: Pharmacokinetic evaluation performed in treatment Cycle 1 (cycle duration is 28 days).

  7. Phase 1: Concentration before dose at steady state (Ctrough) of CTX-712. Plasma samples for PK analyses will be collected at predetermined time points and analyzed.

    Measured: Pharmacokinetic evaluation performed in treatment Cycles 1, 2 and 4 (cycle duration is 28 days).

  8. Phase 1: Area under the plasma concentration time curve (AUC) of CTX-712. Plasma samples for PK analyses will be collected at predetermined time points and analyzed.

    Measured: Pharmacokinetic evaluation performed in treatment Cycle 1 (cycle duration is 28 days).

  9. Phase 1: Volume of distribution (Vd) of CTX-712. Plasma samples for PK analyses will be collected at predetermined time points and analyzed.

    Measured: Pharmacokinetic evaluation performed in treatment Cycle 1 (cycle duration is 28 days).

  10. Phase 1: Elimination half-life of plasma concentration of CTX-712 at terminal phase (T1/2). Plasma samples for PK analyses will be collected at predetermined time points and analyzed.

    Measured: Pharmacokinetic evaluation performed in treatment Cycle 1 (cycle duration is 28 days).

  11. Phase 1: Clearance (CL) of CTX-712. Plasma samples for PK analyses will be collected at predetermined time points and analyzed.

    Measured: Pharmacokinetic evaluation performed in treatment Cycle 1 (cycle duration is 28 days).

  12. Phase 1: Measurement of the change in RNA splicing by CTX-712 in peripheral blood samples as pharmacodynamic markers. Peripheral blood samples for PD analyses will be collected at predetermined time points and analyzed.

    Measured: Pharmacodynamic evaluation performed in treatment Cycle 1 (cycle duration is 28 days).

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing CTX-712 in people with Acute Myeloid Leukemia and Myelodysplastic Syndromes, run by Chordia Therapeutics, Inc. at 8 sites in United States.

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 12 inclusion and 18 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 13 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in United States. 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 Laurie F Graham, RN, MSN ((609) 608-2152, lgraham@theradex.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Phase 1: Frequency of treatment-emergent adverse events (TEAEs) and serious adverse events (SAEs) related to CTX-712. (time frame: Adverse events are collected from time of informed consent through 28 days after last dose of CTX-712.). 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?

On the ClinicalTrials.gov record for NCT05732103, which also lists 2 linked publications.

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 13 Apr 2026; AzTrials last refreshed its copy on 6 Nov 2026.
