  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • In Cohorts I and II, patients must have R/R AML or MDS (venetoclax naïve or venetoclax exposed)
  • Relapsed AML is defined as the appearance of 5% or greater myeloblasts in the bone marrow or peripheral blood after achieving a complete remission (CR), CR with partial hematologic recovery (CRh), or CR with incomplete hematologic recovery (CRi). Patients with a mutation in FLT3, IDH1 or IDH2 must have failed or been intolerant of a corresponding Food and Drug Administration (FDA) approved FLT3, IDH1 or IDH2 inhibitor before enrolling on study. The initial diagnosis of AML is defined by the ELN 2022 criteria, and therefore patients with either AML (peripheral blood or bone marrow blasts ≥ 20% or blasts ≥ 10% with recurrent genetic abnormalities) or MDS/AML (peripheral blood or bone marrow blasts 10-19%) are eligible
  • Refractory AML is defined as failure to achieve a CR, CRh, or CRi after one of the following regimens: (i) ≥ 2 cycles of intensive induction chemotherapy with a cytarabine containing regimen (e.g., 7+3, mitoxantrone, etoposide, cytarabine [MEC], high-dose cytarabine [HIDAC], reinduction chemotherapy such as 5 + 2, etc.) or, (ii) ≥ 2 cycles of hypomethylating agent (HMA)/venetoclax or low-dose cytarabine (LDAC)/glasdegib or, (iii) ≥ 4 cycles of HMA monotherapy. The initial diagnosis of AML is defined by the ELN 2022 criteria, and therefore patients with either AML (peripheral blood or bone marrow blasts ≥ 20% or blasts ≥ 10% with recurrent genetic abnormalities) or MDS/AML (peripheral blood or bone marrow blasts 10-19%) are eligible
  • Patients with MDS/AML (blasts 10-19%) who progress to AML (blasts ≥ 20%) after treatment will be considered relapsed or refractory MDS/AML, and not as newly-diagnosed AML (i.e. the patients' treatment history for eligibility purposes does not reset)
  • Relapsed MDS is defined as: (i) Intermediate, high, or very high-risk disease by International Prognostic Scoring System-Revised (IPSS-R) and, (ii) Any relapse after achieving any 2023 IWG MDS defined response
  • Refractory MDS is defined as: (i) Intermediate, high, or very high-risk disease by IPSS-R and > 5% blasts in the bone marrow or peripheral blood, (ii) Failure to achieve a response (as per IWG 2006 criteria) after ≥ 4 cycles of HMA monotherapy, or (iii) ≥ 2 cycles of HMA + venetoclax
Show all 24Show fewer
  • In Cohort III, patients must have prior untreated high-risk MDS
  • MDS with > 5% blasts in the bone marrow or peripheral blood AND
  • IPSS-R high or very high-risk disease OR
  • Molecular International Prognostic Scoring System (IPSS-M) high or very high-risk disease
  • No more than one single prior cycle of DNMTi therapy
  • Prior use of erythropoiesis stimulating agents (ESA), thrombopoietin agonists, lenalidomide, and luspatercept are allowed
  • Age ≥ 18 years. Because no dosing or adverse event data are currently available on the use of SM08502 (cirtuvivint) in combination with ASTX727 in patients < 18 years of age, children are excluded from this study
  • Eastern Cooperative Oncology Group (ECOG) performance status ≤ 3
  • Total bilirubin ≤ 2 x institutional upper limit of normal (ULN) (unless bilirubin rise is due to Gilbert's syndrome or of non-hepatic origin; in that case a cut off of ≤ 4 × institutional ULN will be used)
  • Aspartate aminotransferase (AST)(serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT)(serum glutamic pyruvic transaminase [SGPT]) ≤ 3 x institutional ULN (unless considered due to organ involvement by the patient's myeloid malignancy; in that case a cut off of ≤ 5 x institutional ULN will be used)
  • Glomerular filtration rate (GFR) ≥ 45 mL/min/1.73m^2
  • If female, patient must be either:
  • Postmenopausal (surgically sterile or age > 55 years with no menses for 12 or more months without an alternative medical cause or age equal to 55 or less with no menses for 12 or more months without an alternative medical cause and a follicle stimulating hormone [FSH] level > 40 IU/L); or
  • Of children bearing potential. These patients must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Patient must agree to have a negative urine or serum beta-human chorionic gonadotropin (HCG) test result during screening and repeated within 7 days prior to study drug (local labs are allowed) to be eligible
  • The effects of SM08502 (cirtuvivint) and ASTX727 on the developing human fetus are unknown. For this reason, and because these agents are known to be teratogenic, women of child-bearing potential must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and during the treatment therapy. Women of childbearing age should agree to use adequate contraception for 7 months after completion of SM08502 (cirtuvivint) administration. For ASTX727, adequate contraception must continue for at least 6 months after last dose of ASTX727. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study and for the duration of the study and at least 4 months after the last dose of SM08502 (cirtuvivint) and 3 months after last dose of ASTX727. Women who are lactating must refrain from breastfeed during the study and at least for two weeks after last dose of ASTX727
  • Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial
  • HIV-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible for this trial
  • Ability to understand and the willingness to sign a written informed consent document. Legally authorized representatives may sign and give informed consent on behalf of study participants

Patients who had prior HCV that has been definitively treated with negative HCV viral load prior to study initiation and no evidence of cirrhosis, are allowed to participate. If there is no known history of HBV infection no HBV studies need to be obtained. If there is no known history of HCV infection, no HCV studies need to be obtained
  • Patients with uncontrolled intercurrent illness or any other significant condition(s) that would make participation in this protocol unreasonably hazardous
  • Pregnant and lactating women are excluded from this study because SM08502 (cirtuvivint) is a small molecule inhibitor of CLK DYRK with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with SM08502 (cirtuvivint), breastfeeding should be discontinued if the mother is treated with SM08502 (cirtuvivint). These potential risks may also apply to other agents used in this study

About this study

Official title: A Phase I Study Evaluating the Safety of Cirtuvivint as Monotherapy and in Combination With ASTX727 in Patients With Myelodysplastic Syndromes (MDS) and Acute Myeloid Leukemia (AML)

This phase I trial tests the safety, side effects, and best dose of SM08502 (cirtuvivint) alone and in combination with ASTX727 in treating patients with acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS). Cirtuvivint may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. ASTX727 is a combination of two drugs, decitabine and cedazuridine. Decitabine is in a class of medications called hypomethylation agents. It works by helping the bone marrow produce normal blood cells and by killing abnormal cells in the bone marrow. Cedazuridine is in a class of medications called cytidine deaminase inhibitors. It prevents the breakdown of decitabine, making it more available in the body so that decitabine will have a greater effect. Giving cirtuvivint alone or in combination with ASTX727 may be safe, tolerable, and/or effective in treating patients with AML and MDS.

Read the detailed description

PRIMARY OBJECTIVE:

  1. To determine the recommended phase 2 dose (RP2D) of SM08502 (cirtuvivint) as monotherapy in relapsed/refractory (R/R) acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS) (Cohort I and II) and in combination with decitabine and cedazuridine (ASTX727) in frontline MDS (Cohort III).

SECONDARY OBJECTIVES:

  1. To assess the safety/tolerability of SM08502 (cirtuvivint) as monotherapy in R/R AML and MDS (Cohort I and II) and in combination with ASTX727 in frontline MDS (Cohort III).

II. To assess the pharmacokinetics (PK), and pharmacodynamics (PD) of SM08502 (cirtuvivint) as monotherapy in R/R AML and MDS (Cohort I and II) and in combination with ASTX727 in frontline MDS (Cohort III).

III. To determine the preliminary efficacy of the combination of SM08502 (cirtuvivint) as monotherapy in R/R AML and MDS (Cohort I and II) and in combination with ASTX727 in frontline MDS (Cohort III) by assessing the response rate as defined by the 2022 European LeukemiaNet (ELN) response criteria for AML (Döhner et al., 2022) and International Working Group (IWG) 2023 response criteria for MDS (Zeidan et al., 2023).

IV. To explore survival outcomes achieved with SM08502 (cirtuvivint) as monotherapy in R/R AML and MDS (Cohort I and II) and in combination with ASTX727 in frontline MDS (Cohort III) by assessing 1 year event free survival (EFS) and overall survival (OS) rate.

  1. To observe and record anti-tumor activity. VI. To evaluate the best schedule to move forward with in Phase 2.

OUTLINE: This is a dose-escalation study of cirtuvivint as monotherapy. Patients are assigned to 1 of 3 cohorts.

COHORT I: Patients receive cirtuvivint orally (PO) once daily (QD) on days 1-5, 8-12, 15-19, and 22-26 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients undergo echocardiography (ECHO) or multigated acquisition scan (MUGA) at screening. In addition, patients undergo blood sample collection and bone marrow aspiration at screening and on study.

COHORT II: Patients receive cirtuvivint PO QD on days 1, 4, 8, 11, 15, 18, 22, and 25 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients undergo ECHO or MUGA at screening. In addition, patients undergo blood sample collection and bone marrow aspiration at screening and on study.

COHORT III: Patients receive cirtuvivint PO QD on days 1, 4, 8, 11, 15, 18, 22, and 25 and ASTX727 PO QD on days 1-5 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients undergo ECHO or MUGA at screening. In addition, patients undergo blood sample collection and bone marrow aspiration at screening and on study.

After completion of study treatment, patients are followed up for 30 days, every 3 months for 2 years then every 6 months for up to 3 years.

What is being measured

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

  1. Maximum tolerated dose (MTD)

    The MTD of cirtuvivint as monotherapy in relapsed/refractory (R/R) acute myeloid leukemia (AML) and R/R myelodysplastic syndrome (MDS) (Cohort I and II) and in combination with ASTX727 in frontline MDS (Cohort III). MTD will be defined as the highest dose level at which 0/6 or 1/6 subjects experience a dose-limiting toxicity.

    Measured: Up to day 28

  2. Recommended phase 2 dose (RP2D)

    The RP2D will be based on the MTD in both Cohort I and II as well as pharmacokinetic, pharmacodynamic and response data from Cohort I and II.

    Measured: Up to 3 years

Secondary outcomes (4)

  1. Incidence of adverse events (AEs)

    AEs will be graded using Common Terminology Criteria for Adverse Events version 5.0 and described by frequency, duration, and severity of treatment-emergent, treatment-related, and serious AEs. All reported toxicities, regardless of attribution, will be summarized by toxicity type and maximum grade, and sorted by number of patients experiencing the toxicity for each dosing cohort and overall.

    Measured: Up to 30 days after last dose of study treatment

  2. Clinical response

    Clinical response will be assessed based on the 2022 European LeukemiaNet criteria for AML and the 2023 International Working Group criteria for MDS. Clinical response will be described using descriptive statistics. Point estimates and exact binomial 95% confidence intervals (CIs) will be provided for binary endpoints such as response rate in participants treated at MTD.

    Measured: Up to 5 years after end of treatment

  3. Event-free survival (EFS)

    The Kaplan-Meier method will be used to estimated EFS with its 95% CI.

    Measured: Up to 1 year

  4. Overall survival (OS)

    The Kaplan-Meier method will be used to estimated OS with its 95% CI.

    Measured: Up to 1 year

The record lists 23 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 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?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Maximum tolerated dose (MTD) (time frame: Up to day 28). The study lists 2 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 NCT06484062, which also lists 1 linked publication.

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 3 Nov 2026.
