About this study

Official title: A Feasibility Study of Organ-Sparing Marrow-Targeted Irradiation (OSMI) to Condition Patients With High-Risk Hematologic Malignancies Prior to Allogeneic Hematopoietic Stem Cell Transplantation

This pilot clinical trial aims to assess feasibility and tolerability of using an LINAC based "organ-sparing marrow-targeted irradiation" to condition patients with high-risk hematological malignancies who are otherwise ineligible to undergo myeloablative Total body irradiation (TBI)-based conditioning prior to allogeneic stem cell transplant. The target patient populations are those with ALL, AML, MDS who are either elderly (>50 years of age) but healthy, or younger patients with worse medical comorbidities (HCT-Specific Comorbidity Index Score (HCT-CI) > 4). The goal is to have the patients benefit from potentially more efficacious myeloablative radiation based conditioning approach without the side effects associated with TBI.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To assess feasibility and tolerability of OSMI based hematopoietic stem cell transplant (HSCT) as defined by transplant-related mortality (TRM) at day 30 as well as rate of grade II/III organ toxicity (defined by Bearman Regimen-Related Toxicities Scale) attributable to conditioning occurring within 30 days.

SECONDARY OBJECTIVES:

  1. Day 100 transplant-related mortality (TRM). II. Donor chimerism assessment at day 100 (to assess failure of engraftment rate).

III. Incidence of acute graft-versus-host disease (aGVHD) by day 100. IV. Incidence of chronic GVHD at one year. V. Cumulative incidence of grade II organ toxicity through day 100. VI. Rate and kinetics of hematopoietic recovery. VII. Incidence of graft failure (primary and secondary). VIII. Rate of infectious complications. IX. Cumulative incidence of relapse, overall survival, and progression-free survival at 1 year.

OUTLINE:

CONDITIONING REGIMEN: Patients undergo organ-sparing marrow irradiation twice daily (BID) on days -6 to -4 and receive cyclophosphamide intravenously (IV) over 1-2 hours every 24 hours on days -3 to -2. Patients with an unrelated donor also receive anti-thymocyte globulin every 24 hours on days -4 to -2.

GVHD PROPHYLAXIS: Patients receive tacrolimus IV or orally (PO) beginning on day -1 and continuing for at least 6 months and methotrexate IV on days 1, 3, 6, and 11.

TRANSPLANT: Patients undergo allogeneic peripheral blood progenitor cell or bone marrow transplant on day 0.

After completion of study treatment, patients are followed up weekly for 12 weeks, at day 100, and then at 6 and 12 months.

What is being measured

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

  1. TRM, defined as death occurring in a patient from causes other than disease relapse

    Proportions will be derived for incidence of TRM divided by all evaluable patients along with corresponding 95% binomial confidence intervals.

    Measured: At day 30 post-transplant

  2. Rate of grade II/III organ toxicity, defined by the Bearman Regimen-Related Toxicities Scale

    Toxicities will be tabulated by grade for each cohort, by type of toxicity, as well as the maximum grade overall. Toxicity frequencies will be described for the day +30, day +100, and one year time intervals as well as cumulative over time. Proportions will be derived for incidence of grade II/III organ toxicity divided by all evaluable patients along with corresponding 95% binomial confidence intervals.

    Measured: Up to 30 days

Secondary outcomes (12)

  1. TRM

    Proportions will be derived for incidence of toxicity divided by all evaluable patients along with corresponding 95% binomial confidence intervals.

    Measured: Day 100 post-transplant

  2. Donor chimerism

    Donor chimerism is used to assess failure of engraftment rate.

    Measured: Day 100

  3. Incidence of aGVHD, graded according to Ohio State University Bone Marrow Transplant (OSU BMT) Program policy

    The first day of aGVHD onset at a certain grade will be used to calculate cumulative incidence curves for that GVHD grade.

    Measured: Up to day 100

  4. Incidence of chronic GVHD, scored according to the OSU BMT Program policy

    The first day of chronic GVHD onset will be used to calculate cumulative incidence curves. Rates and severity of chronic GHVD will be calculated.

    Measured: At 1 year

  5. Cumulative incidence of grade II organ toxicity

    Toxicity will be tabulated by grade for each cohort, by type of toxicity as well as the maximum grade overall.

    Measured: Up to day 100

  6. Incidence of hematopoietic recovery

    The rate and kinetics of hematopoietic recovery will be assessed. The kinetics of post-transplant recovery of both neutrophil and platelet engraftment will be assessed.

    Measured: Up to day 100

  7. Incidence of graft failure

    Primary graft failure (defined by the lack of neutrophil engraftment by 28 days) and secondary graft failure (defined by initial neutrophil engraftment followed by subsequent decline in neutrophil counts < 500/uL unresponsive to growth factor therapy) will be assessed on days 30 and 100 and at 1 year post-transplant.

    Measured: Up to 1 year post-transplant

  8. Rate of infectious complications

    The number of infections and the number of patients experiencing infections will be tabulated by type of infection, severity, and time period after transplant. The cumulative incidence of severe, life-threatening, or fatal infections will be tabulated.

    Measured: Up to 12 months

  9. Incidence of relapse

    Measured: Time from start of conditioning to relapse, assessed at 1 year

  10. Overall survival

    Measured: Time from start of conditioning to death, loss to follow up, or end of study, whichever comes first, assessed at 1 year

  11. Progression-free survival

    Patients are considered a failure of this endpoint if they die or suffer from disease relapse or progression.

    Measured: Time from start of conditioning to relapse, progression, death, initiation of non-protocol therapy, loss to follow up or end of study, whichever comes first, assessed at 1 year

  12. Immune reconstitution

    Quantitative assessments of peripheral blood CD3, CD4, CD8, CD19, and CD56 positive lymphocytes will be done throw flow cytometric analysis at baseline, 100 days, and 12 months post transplantation.

    Measured: Up to 12 months post transplant

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing radiation therapy, cyclophosphamide and anti-thymocyte globulin in people with Adult Acute Lymphoblastic Leukemia in Remission and Adult Acute Myeloid Leukemia in Remission, run by Sumithira Vasu 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 15 inclusion and 21 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 21 Sep 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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

TRM, defined as death occurring in a patient from causes other than disease relapse (time frame: At day 30 post-transplant). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02122081.

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 21 Sep 2023.
