Summary
This study is a Phase 1, non-randomized, open-label/Phase 2 randomized, blinded study of ProTmune (ex vivo programmed mobilized peripheral blood cells) versus non-programmed mobilized peripheral blood cells for allogeneic hematopoietic cell transplantation (HCT) in adult subjects aged 18 years and older with hematologic malignancies. A total of 88 study subjects were treated in the trial at approximately 15 centers in the US.
Eligibility Criteria
Key Inclusion Criteria
- Male and female patients aged 18 years and older, inclusive;
- Patients must have a hematologic malignancy for which allogeneic hematopoietic peripheral blood cell transplantation is deemed clinically appropriate.
Eligible diseases and stages include the following:
- Acute myeloid leukemia
- Acute lymphoblastic leukemia, including T lymphoblastic lymphoma with a history of marrow involvement
- Myelodysplastic Syndrome
- Chronic myelogenous leukemia
- Availability of a suitable 8/8 HLA-A, -B, -C, and -DRB1-matched unrelated mPB donor;
- mBP donor collection that meets protocol specifications;
- Adequate performance status, defined as Karnofsky score greater than or equal to 70%;
- For female patients of childbearing potential, all of the following criteria must be met:
- They are not pregnant (i.e., female patients must have a negative serum pregnancy test at screening);
- They are not breastfeeding;
- They do not plan to become pregnant during the study; and
- They are using an effective method of contraception from screening to the end of the study, unless their sexual partner is surgically sterile.
- For male patients, agreement to use condoms with spermicide during sexual intercourse from screening to the end of study; and
- Willingness and ability to sign an IRB/IEC-approved ICF before performance of any study-specific procedures or tests and to comply with protocol visits, and study procedures.
Key Exclusion Criteria
- Phase 1 only: Known bone marrow fibrosis; Phase 2 only: Bone marrow fibrosis grade 3 (severe) or greater;
- Positive serology for human immunodeficiency virus (HIV) or human T-cell lymphotropic virus (HTLV) at any time prior to enrollment;
- Currently uncontrolled bacterial, viral, or fungal infection (progression of clinical symptoms despite therapy);
- Prior autologous or allogeneic HCT;
- Active malignancy, other than the one for which the allogeneic mPB transplant is being performed, within 12 months of enrollment, excluding superficial basal cell and carcinoma in situ cervical cancer;
- Pulmonary disease, renal dysfunction, hepatic disease, cardiac disease, neurologic disease;
- Participation in another clinical trial involving an investigational product within 30 days prior to screening; or
- Any condition or therapy, which, in the opinion of the Investigator, might pose a risk to the patient or make participation in the study not in the best interest of the patient.
