Trial summary

The purpose of this protocol is to provide access to the CliniMACS® System to hematopoietic cell transplant (HSCT) patients who do not have a matched related donor. The CliniMACS system is currently approved for use in patients who have AML, and a genetically matched sibling donor. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages Up to 35 years
  • All sexes
  • No healthy volunteers
  • Child, Adult

Who may be able to join

  • Participant age is 0 (newborn) to 35 years-old.
  • Participant has a disorder affecting the hematopoietic system that are inherited, acquired, or a result from the myeloablative treatment that can benefit from alternative stem cell transplantation according to standard practice guidelines for including patients for transplant.
  • Participant's medical screening clears s/he for allogeneic transplantation as per current institutional SOP based on standards of foundation for accreditation of cellular therapy and stem cell transplantation (FACT);
  • Participant must lack a healthy, HLA-identical related or unrelated donor unless s/he has a borderline organ function that will preclude the recipient from receiving a curative therapy due to the need of post-HSCT immunosuppressive therapy.
  • Participant must have a matched or mismatched-related donor who is:
  • Able to receive granulocyte colony-stimulating factor (G-CSF) and undergo apheresis either through placement of catheters in antecubital veins or a temporary central venous catheter OR agrees on a bone marrow harvest;
Show all 9Show fewer
  • Healthy as per donor selection screening (following current SOP based on standards of foundation for accreditation of cellular therapy and stem cell transplantation - FACT);
  • Willing to participate and sign consent.
  • Participant or Legal Authorized Representative is able to sign informed consent (and signed assent, if applicable) for transplant.

Who cannot join

  • Participant does not qualify for an allogeneic transplant due to medical screening, underlying disease, or lack of alternative donors.
  • Any condition that compromises compliance with the procedures of this protocol, as judged by the principal investigator.

About this study

Official title: An Expanded Access Study Using the CliniMACS System to Offer Therapeutic Manipulated Grafts That Are CD34 Cell Enriched and T Cell Depleted for Allogeneic Stem Cell Recipients With Mismatched Related Donors or Borderline Organ Function

The purpose of this protocol is to provide access to the CliniMACS® System to hematopoietic cell transplant (HSCT) patients who do not have a matched related donor. The CliniMACS system is currently approved for use in patients who have AML, and a genetically matched sibling donor. Through this protocol, the investigators will be able to offer potentially life-saving transplants to patients who have genetically mis-matched donor, who have no other options for treatment.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Patients With Severe (Grade III/IV) Acute Graft vs Host Disease (GVHD)

    GVHD is a condition that occurs when donor bone marrow or stem cells attack the recipient.

    Measured: Day +100

Secondary outcomes (10)
  1. Number of Participants With Graft Failure

    Failure of donor stem cells to make neutrophils

    Measured: Up to Day +42 after stem cell transplant

  2. Length of Time to Engraftment

    Absolute neutrophil count (ANC) >500 for 3 consecutive days and >80% donor cells in blood.

    Measured: up to +1 year post-transplant

  3. Chimerism of Donor Cells

    The percentage of donor cells for all evaluable (without disease progression) patients

    Measured: Day +100 post-transplant

  4. Immune Recovery (CD4)

    The time to CD4 count >100

    Measured: up to +1 year post-transplant

  5. Number of Participants With Immune Recovery (CD4 >200) by Year 1

    Measured: up to +1 year post-transplant

  6. Immune Recovery Shown as Phytohemagglutin (PHA)

    Immune recovery defined as achieving normal levels of PHA (53,000-200,000 CPM)

    Measured: 6 months and 1 year post-transplant

  7. Number of Patients With Post-transplant Lymphoproliferative Disease (PTLD)

    Post-transplant lymphoproliferative disorder (PTLD) is a well-known, life-threatening complication of organ transplantation, predominantly occurring after solid organ transplantation (SOT) and hematopoietic stem cell transplantation (HSCT).

    Measured: up to +1 year post-transplant

  8. Number of Patients With Severe Toxicities

    Incidence of transplant-related toxicities

    Measured: up to +1 year post-transplant

  9. Number of Participants Experiencing Post-transplant Infections

    Post-transplant infections will be described by incidence and type. Participants may have had more than one type of infection.

    Measured: up to +1 year post-transplant

  10. Transplant-related Mortality (TRM)

    Death related to transplant

    Measured: at Day +100 and +1 year post-transplant

Questions about this trial

What is this clinical trial studying?

A study testing CliniMACS CD34+ cell enrichment and T-cell depletion in people with Malignant Diseases and Non-malignant Diseases, run by Rajni Agarwal at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 Jun 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 26 Jun 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Patients With Severe (Grade III/IV) Acute Graft vs Host Disease (GVHD) (time frame: Day +100). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Jun 2023.
