High Dose Ruxolitinib and Allogeneic Stem Cell Transplantation in Myelofibrosis Patients With Splenomegaly

Recruiting now · Phase 2

Conditions studied: Splenomegaly, Myelofibrosis

In brief

To learn if giving ruxolitinib and busulfan before a stem cell transplant can help to reduce spleen size and help the transplant to succeed.

Who can join

Age: 18 and older, up to 75. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

Participants 18 years to less than or equal to 75 years.
Able to provide written consent.
Primary or secondary Myelofibrosis (may have received Jak inhibitors including ruxolitinib)
Enlarged spleen by palpation or imaging. For the purpose of this study, splenomegaly is defined as any clinically palpable spleen or spleen larger than 12 cms on imaging.
Has a fully matched (8/8:HLA A, B, C, DRB1) related or matched unrelated donor.
Adequate renal function, including:
a. Serum creatinine </= 1.5 mg/dL or estimated Glomerular Filtration Rate (eGFR using the CKI-EPI equation) >/= 40 ml/min/1.73 m2.
Adequate liver function, including:
ALT/AST </= 3 x ULN
Direct bilirubin </= 1mg/dL
No history of liver cirrhosis. No ascites.
Female participants of childbearing potential must have negative results for a serum pregnancy test. Female participants must agree to not breastfeed during the study and for 3 months post-completion of the study therapy.
Subjects who are of childbearing potential, sexually active, and at risk of pregnancy must agree to use a highly effective method of contraception for the duration of the active treatment and at least 3 months post-completion of the study therapy. Highly effective methods of contraception include the following:
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. Men who are able to have children must use effective birth control while on the study. If the male participant fathers a child or suspects that he has fathered a child while on the study, he must immediately notify his doctor.

You may not qualify if…

Positive beta HCG in females of child-bearing potential defined as not postmenopausal for 24 months or no previous surgical sterilization or lactating females.
Ejection fraction <40%
Corrected DLCO < 50%
Evidence of other clinically significant uncontrolled condition(s) including, but not limited to:
Uncontrolled and/or active systemic infection (viral, bacterial or fungal)
Active hepatitis B virus (HBV), hepatitis C (HCV), HIV or TB infection or requiring treatment for the same.
Thrombosis including MI, Stroke, PE, DVT in the past 6 months
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 positive anti-HBc antibody from intravenous immunoglobulins (IVIG) may participate.
