Study summary

This phase II trial is studying the side effects of giving azacitidine together with gemtuzumab ozogamicin to see how well it works in treating older patients with previously untreated acute myeloid leukemia. Drugs used in chemotherapy, such as azacitidine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Azacitidine may also stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as gemtuzumab ozogamicin, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Giving azacitidine together with gemtuzumab ozogamicin may kill more cancer cells.

Read the detailed description

PRIMARY OBJECTIVES:

I. To test whether outcomes of patients of age 60 or older with previously untreated non-M3 acute myeloid leukemia treated with azacitidine plus gemtuzumab ozogamicin are sufficient to warrant phase III investigation.

II. To estimate the frequency and severity of toxicities of this regimen in the good- and poor-risk groups of patients.

III. To investigate in a preliminary manner the disease-free survival of patients who achieve complete remission and receive post-remission therapy on this study.

IV. To investigate in a preliminary manner the cytogenetic response rates of patients treated with this regimen.

V. To investigate in a preliminary manner the effects of cytogenetic abnormalities, promoter and global methylation changes, and multidrug resistance on overall survival and response to azacitidine plus gemtuzumab ozogamicin therapy.

OUTLINE: Patients are stratified according to risk status (good [60-69 years of age OR Zubrod performance status [PS] 0-1] vs poor [>= 70 years of age AND Zubrod PS 2-3]).

REMISSION INDUCTION THERAPY: Patients receive azacitidine intravenously (IV) over 10-40 minutes or subcutaneously (SC) once daily (QD) on days 1-7 and gemtuzumab ozogamicin IV over 2 hours on day 8. Patients with residual leukemia (blast count >= 5%) receive a second course of induction therapy beginning between days 15-29. Patients achieving complete remission (CR) or morphologic complete remission with incomplete blood count recovery (CRi) go on to receive consolidation therapy.

CONSOLIDATION THERAPY: Patients receive one course of azacitidine and gemtuzumab ozogamicin as in induction therapy (with azacitidine given SC only).

MAINTENANCE THERAPY: Patients receive azacitidine SC on days 1-7. Treatment repeats every 28 days for 4 courses in the absence of disease progression or unacceptable toxicity. Patients undergo bone marrow biopsies for cytogenetic studies at baseline, remission, and relapse or progression (and at completion of treatment if it does not correspond to one of these time points). Marrow and blood samples are submitted to correlatives studies and submitted to Southwest Oncology Group (SWOG) acute lymphoblastic leukemia (ALL)/chronic lymphocytic leukemia (CLL)/chronic myelogenous leukemia (CML) Repository in Seattle, WA.

After completion of study therapy, patients are followed every 2 months for 2 years, every 3 months for 1 year, every 4 months for 1 year, and then every 6 months thereafter.

Terms in these criteria, in plain language(13)

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.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

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.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

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.

Reproductive potential

Able to have children. For women this usually means from the first period until menopause, unless permanently unable to through surgery; for men, unless permanently sterile. Read who the line is about — participants, women, men, or their partners.

Criteria about it usually ask for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

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.

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.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

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.

Absolute neutrophil count (ANC)

The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.

It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Ran from Dec 2008 to primary completion in Jun 2013, 54 months.

Results were first posted in Jan 2014, 7 months after primary completion.

Of 385 non-industry phase 2 interventional studies under Leukemia, Myeloid, Acute, half reached primary completion within 67 months of starting (the median), counting those still running; a quarter within 40 and three quarters within 108. This study's 54 months is below that.

Counting every sponsor, half of 442 studies reached it within 60 months; a quarter within 38 and three quarters within 104.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
