Study summary

This phase II trial studies how well donor umbilical cord blood transplant with ex-vivo expanded cord blood progenitor cells (dilanubicel) works in treating patients with blood cancer. Before the transplant, patients will receive chemotherapy (fludarabine, cyclophosphamide and in some cases thiotepa) and radiation therapy. Giving chemotherapy and total-body irradiation before a donor umbilical cord blood transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. The donated stem cells may also replace the patient's immune cells and help destroy any remaining cancer cells.

Read the detailed description

OUTLINE:

Patients receive either regimen A or regimen B.

REGIMEN A: Patients (10 through 45 years old) receive fludarabine intravenously (IV) over 30 minutes on days -8 to -6 and cyclophosphamide IV on days -7 and -6. Patients undergo total body irradiation (TBI) twice daily (BID) on days -4 to -1. Patients receive unmanipulated cord blood unit IV followed by dilanubicel IV within the next 24 hours on day 0.

REGIMEN B: Patients (10 through 65 years old) receive fludarabine IV over 30-60 minutes on days -6 to -3 and IV over 30 minutes on day -2, cyclophosphamide IV on day -6, and thiotepa IV over 2-4 hours on days -5 and -4. Patients undergo TBI once daily (QD) on days -2 and -1. Patients receive unmanipulated cord blood unit IV followed by dilanubicel IV within the next 24 hours on day 0.

All patients undergo bone marrow aspirate and biopsy as clinically indicated during screening and on study. Patients undergo multigated acquisition scan (MUGA) or echocardiography (ECHO), and computed tomography (CT) during screening. Patients also undergo blood sample collection on study.

After completion of study treatment, patients are followed up at 180 days, 1 year, and 2 years.

Terms in these criteria, in plain language(11)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Relapsed and refractory

Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.

Karnofsky performance status (KPS)

A 0–100 scale of how well someone can carry out everyday activities. 100 is no complaints and no signs of illness; 70 is able to look after yourself but not to work or keep up normal activity; 50 is needing considerable help and frequent medical care.

Studies often ask for 60 or 70 and above. Your doctor gives the score.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Creatinine clearance (CrCl)

How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

LVEF (left ventricular ejection fraction)

The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Allogeneic and autologous transplant

Stem cell (bone marrow) transplants. Allogeneic uses cells from a donor; autologous uses your own cells, collected earlier and given back.

What researchers measure

Primary outcomes

  1. Number of Participants With Graft Failure

    Primary graft failure/rejection as defined by no neutrophil recovery (regardless of donor chimerism) or autologous recovery (neutrophil recovery but \< 10% donor chimerism in blood and bone marrow \[BM\]).

    Time frame: Up to day 45 post-transplant

Secondary outcomes

  1. Number of Participants Who Experienced Grade ≥3 Adverse Events Related to Study Product

    Adverse events (AEs) were graded using the CTCAE v5.0. This outcome measured the number of participants who experienced at least one grade ≥ 3 adverse event considered related to the study product during the period of start of infusion of the study product (Day 0) until 100 days following transplant. An AE is considered related to the study product based on investigator assessment if it was assessed as definitely, probably, or possibly related; unrelated if it is assessed as unlikely related or unrelated. AE severity grade, seriousness, and relatedness were evaluated independently; therefore, grade ≥3 events were not necessarily serious adverse events (SAEs). Reporting of grade ≥3 AEs and all-grade SAEs is provided in the Adverse Events module. Dose-limiting toxicities (DLTs) were predefined.

    Time frame: From study product infusion start through day 100 post-transplant

  2. Time to Neutrophil Engraftment

    The day of neutrophil recovery will be the 1st day of 2 consecutive days of absolute neutrophil count at or above 500 after the 1st post-cord blood transplant nadir.

    Time frame: Up to day 45 post-transplant

  3. Time to Platelet Engraftment

    Measured by the number of participants with a platelet count \> 20,000/ul without subsequent transfusions for 7 days. Participants who did not reach platelet engraftment by day 100 post-transplant were censored at day 100.

    Time frame: Up to day 100 post-transplant

  4. Number of Participants With Acute Graft Versus Host Disease (aGVHD), by Grade

    The presence of aGVHD was assessed using the Acute GVHD Grading Scale and represented as overall grade I-IV, with higher grade indicating worse outcomes. Grade I aGVHD is defined as skin stage 1-2 and stage 0 for both GI and liver. Grade II is stage 3 skin, stage 1 GI, or stage 1 liver. Grade III is stage 4 skin or stage 2-4 GI or stage 2-4 liver, without GVHD as a major contributing cause of death. Grade IV is stage 4 skin or stage 2-4 GI or stage 2-4 liver, with GVHD as a major contributing cause of death.

    Time frame: At day 100 post-transplant

  5. Number of Participants With Chronic Graft Versus Host Disease (cGVHD), by Severity

    The presence of cGVHD was assessed using the Chronic GVHD Grading Scale, with higher severity indicating worse outcomes. Incidence of moderate or severe cGVHD were considered clinically significant. Mild cGVHD is defined as limited organ involvement with minimal functional impairment, typically affecting 1-2 organs/sites with no major impact on daily activities. Moderate cGVHD is indicated by more extensive organ involvement and/or clinically significant functional impairment, but without major disability. Severe cGVHD is defined as major organ involvement with substantial functional impairment or disability, often requiring intensive systemic therapy. Abnormalities that could indicate cGVHD are reviewed for the following organ systems: skin, nails, hair, mouth, eyes, vagina/vulva (for female patients), liver, lung, GI, fasciitis, serositis, muscle, skeletal.

    Time frame: 1 year post-transplant

  6. Number of Participants With Chronic Graft Versus Host Disease (cGVHD), by Severity

    The presence of cGVHD was assessed using the Chronic GVHD Grading Scale, with higher severity indicating worse outcomes. Incidence of moderate or severe cGVHD were considered clinically significant. Mild cGVHD is defined as limited organ involvement with minimal functional impairment, typically affecting 1-2 organs/sites with no major impact on daily activities. Moderate cGVHD is indicated by more extensive organ involvement and/or clinically significant functional impairment, but without major disability. Severe cGVHD is defined as major organ involvement with substantial functional impairment or disability, often requiring intensive systemic therapy. Abnormalities that could indicate cGVHD are reviewed for the following organ systems: skin, nails, hair, mouth, eyes, vagina/vulva (for female patients), liver, lung, GI, fasciitis, serositis, muscle, skeletal.

    Time frame: Up to 2 years post-transplant

  7. Number of Participants Who Experienced Non-relapse Mortality

    Non-relapse mortality (NRM) is defined as death without a prior relapse.

    Time frame: At day 100 post-transplant

  8. Number of Participants Who Experienced Non-relapse Mortality

    Non-relapse mortality (NRM) is defined as death without a prior relapse.

    Time frame: At day 180 post-transplant
