Inclusion criteria
. Patients with any of the following hematologic malignancies:
. AML in first remission (CR1) if they have intermediate- or high-risk cytogenetic and/or molecular features, or patients in second or subsequent complete remission (CR2, CR3, etc.). Complete remission is defined as presence of \<5% blasts in the bone marrow with no morphological evidence of leukemia. Patients in CR with incomplete count recovery may be included.
. ALL with any of the following in CR1 or subsequent complete remission (CR2, CR3, etc.). Complete remission is defined as presence of \<5% blasts in the bone marrow with no morphological evidence of leukemia. Patients in CR with incomplete count recovery may be included.
. MDS with a revised International Prognostic System Score (IPSS-R) of greater than 3 at diagnosis. Patients must have \<10% blasts in the bone marrow documented within 30 days of transplant.\*
. Therapy-related myelodysplastic disorder (t-MDS). Patients must have \<10% blasts in the bone marrow documented within 30 days of transplant.\*
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.
. CMML type 1 or 2. Patients must have \<10% blasts in the bone marrow documented within 30 days of transplant.\* \*Patients with MDS, t-MDS, and CMML will be included only in the phase I portion of the study.
. Patient age ≥ 18 years
. KPS ≥70%
Exclusion criteria
. Pregnant or nursing females or women of reproductive capability who are unwilling to completely abstain from heterosexual sex or practice effective methods of contraception from start of conditioning through a minimum of 90 days after the last dose of study drug. A woman of reproductive capability is one who has not undergone a hysterectomy (removal of the womb), has not had both ovaries removed, or has not been post-menopausal (stopped menstrual periods) for more than 24 consecutive months.

Male subjects who refuse to practice effective barrier contraception from the start of conditioning through a minimum of 90 days after the last dose of study drug, or completely abstain from heterosexual intercourse. This must be done even if they are surgically sterilized (i.e., post- vasectomy).
. Inability to provide informed consent.
. Patient had myocardial infarction within 6 months prior to enrollment or has NYHA Class III or IV heart failure, uncontrolled angina, severe uncontrolled ventricular arrhythmias, or electrocardiographic evidence of acute ischemia or active conduction system abnormalities. Prior to study entry, any ECG abnormality at screening must be documented by the investigator as not medically relevant.
. Patients with active central nervous system leukemia
. Prior allogeneic HSCT or an autologous HSCT in past 12 months
. Patients with diabetes mellitus requiring insulin secretagogues and/or insulin at time of enrollment
