A Randomized Study to Compare Post-transplant Cyclophosphamide, Sirolimus, Ruxolitinib and Post-transplant Cyclophosphamide, Sirolimus, Mycophenolate Mofetil to Prevent Graft Versus Host Disease

Recruiting now · Phase 2

Conditions studied: AML

In brief

The goal of this clinical research study is to compare the effects of these drug combinations (cyclophosphamide, sirolimus, and MMF vs cyclophosphamide, sirolimus, and ruxolitinib) on the prevention of GVHD after a stem cell transplant.

Who can join

Age: 65 and older, up to 75. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

Age ≥ 65 and < 75 years are eligible if they have one of the following diseases.
Acute Myeloid Leukemia
Myelodysplastic syndrome
Chronic myelomonocytic leukemia
Available HLA-identical or haploidentical related donor or a 7/8 or 8/8 HLA matched unrelated donor.
Peripheral blood stem cells as a graft source
Subject must voluntarily sign an informed consent.
Adequate organ function per local laboratory reference range as follows: - Aspartate transaminase (AST) and alanine transaminase (ALT) < 3.0X ULN - Total Bilirubin <1.5 x ULN (unless bilirubin rise is due to Gilbert's syndrome or of nonhepatic origin) - Subject must have adequate renal function as demonstrated by a creatinine clearance ≥ 40 mL/min/1.73 m2 (as reported in epic using 2021 CKD-EPI creatinine equation)
DLCO corrected for Hgb, if applicable) ≥ 50% of predicted
Ejection Fraction ≥ 50%
The effects on the developing human fetus are unknown. For this reason and as well as other therapeutic agents used in this trial are known to be teratogenic, women of child-bearing potential and men 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. (Refer to Pregnancy Assessment Policy MD Anderson Institutional Policy # CLN1114). This includes all female patients, between the onset of menses (as early as 8 years of age) and 55 years unless the patient presents with an applicable exclusionary factor which may be one of the following:
Postmenopausal (no menses in greater than or equal to 12 consecutive months).
History of hysterectomy or bilateral salpingo-oophorectomy.
Ovarian failure (Follicle Stimulating Hormone and Estradiol in menopausal range, who have received Whole Pelvic Radiation Therapy).
History of bilateral tubal ligation or another surgical sterilization procedure.
Approved methods of birth control are as follows: Hormonal contraception (i.e. birth control pills, injection, implant, transdermal patch, vaginal ring), Intrauterine device (IUD), Tubal Ligation or hysterectomy, Subject/Partner post vasectomy, Implantable or injectable contraceptives, and condoms plus spermicide. Not engaging in sexual activity for the total duration of the trial and the drug washout period is an acceptable practice; however periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of birth control. 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, for the duration of study participation, and 4 months after completion of study agent administration.

You may not qualify if…

Subject is known to be positive for HIV.
Subject has acute promyelocytic leukemia.
Subject has known active CNS involvement with AML.
Hematopoietic Cell Transplantation Comorbidity Index (HCT-CI) score of >5
Evidence of other clinically significant uncontrolled condition(s) including, but not limited to:
Uncontrolled and/or active systemic infection (viral, bacterial or fungal)
Chronic hepatitis B virus (HBV) or hepatitis C (HCV) requiring treatment. Note: subjects with serologic evidence of prior vaccination to HBV (i.e. hepatitis B surface (HBs) antigen negative-, anti-HBs antibody positive and anti-hepatitis B core (HBc) antibody negative) or subjects with positive anti-HBc antibody but negative Hep B DNA may participate.
Cardiac history of CHF requiring treatment or Ejection Fraction < 50% or unstable angina or MI within 1 year of study entry
Major adverse cardiac events such as MI/stroke and pulmonary embolism (PE)/deep vein thrombosis (DVT) within 6 months. Recent history of Central line-associated DVT may be allowed after discussion with PI.
Current and/or history of active TB
White Blood Cell count > 25 X 109 /L.
Pregnant women are excluded from this study because the study agent has unknown 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, breastfeeding should be discontinued if the mother is treated with the study agent. These potential risks may also apply to other agents used in this study.
