Testing the Use of an IDH1 Inhibitor, Olutasidenib, in Acute Myeloid Leukemia Added to ASTX727 and Venetoclax; in High-Risk MDS Added to ASTX727; and Alone in Low Risk MDS (A MyeloMATCH Treatment Substudy)

Plain-language summary
This phase II MyeloMATCH treatment substudy tests the addition of olutasidenib to usual treatment in patients with higher-risk myelodysplastic syndrome (MDS) or patients with acute myeloid leukemia (AML) with a mutation in the IDH1 gene. Olutasidenib blocks the protein made by the mutated IDH1 gene. Blocking this protein may help keep cancer cells from growing. For patients with MDS, olutasidenib will be added to decitabine-cedazuridine (also called ASTX727). Decitabine is in a class of medications called hypomethylating agents and is the standard treatment for MDS. It works by helping the bone marrow produce normal blood cells and by killing abnormal cells in the bone marrow. The cedazuridine makes it possible to take the decitabine by mouth. Adding olutasidenib to the usual treatment for MDS (ASTX727) may increase the likelihood of going into remission. For patients with AML, olutasidenib and ASTX727 will be combined with venetoclax, a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. Venetoclax may stop the growth of cancer cells by blocking BCL-2, a protein needed for cancer cell survival. Adding olutasidenib to the usual treatment for AML (ASTX727 and venetoclax) may increase the likelihood of going into remission. For low risk MDS, the substudy tests whether giving olutasidenib alone helps improve blood counts.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Patient must be enrolled on the MYELOMATCH Master Screening and Reassessment Protocol (MSRP), determined to have an IDH1-R132 mutation and assigned to this trial via MATCHBox
* REGISTRATION ELIGIBILITY CRITERIA (STEP 1):
* Documentation of IDH1 mutated MDS or AML
* COHORT A: Age ≥ 60 years or adults ˂ 60 and ≥ 18 who in the opinion of the treating physician are not candidates for intensive, cytarabine-based induction based on clinical status (i.e., performance status), organ dysfunction, or disease biology with a morphologically confirmed diagnosis of AML with ≥ 20% myeloblasts in the bone marrow or peripheral blood
* COHORT B: Age ≥ 18 years with treatment-naïve HR-MDS with an IPSS-R score ≥ 4.0 at time of enrollment
* COHORT C: Age ≥ 18 years with LR-MDS with an IPSS-R score ≤ 3.5 at time of enrollment and either:
* RBC-TD anemia (≥ 2 units/8 weeks in the 16 weeks prior to registration) who have failed or are ineligible to erythropoiesis-stimulating agents (ESA) therapy
* Presence of either neutropenia (\< 1 x 10\^9/L) or thrombocytopenia (\< 100 x 10\^9/L) for use as frontline therapy or after failure of prior therapies, including growth factors. Patient must be hypomethylating agent (HMA)-naïve
* No prior therapy excluding:
* Cohort A: hydroxyurea and all-trans retinoic acid (ATRA) for AML
* Cohort B: ESAs (erythropoiesis-stimulating agents) and/or TGF-β inhibitors for HR-MDS
* Cohort C: ESAs (erythropoiesis-stimulating agents, TGF-β inh…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
