Study summary

This phase III trial compares the effect of high dose chemotherapy and the patients' own (autologous) stem cells to observation only in patients with peripheral T-cell lymphoma who achieved a complete response after initial chemotherapy. Usual treatment after a complete response may include observation or high dose chemotherapy followed by an autologous stem cell transplant, however, it is not known if a transplant if beneficial. Giving chemotherapy before a stem cell transplant helps kill cancer cells in the body and helps make room in the patient's bone marrow for new blood-forming cells (stem cells) to grow. Stem cells removed prior to treatment are then returned to the patient to replace the blood forming cells that were destroyed by the chemotherapy. Giving high dose chemotherapy followed by an autologous stem cell transplant may be more effective compared to observation only in treating patients with peripheral T-cell lymphoma who have achieved a complete response after initial chemotherapy.

Read the detailed description

PRIMARY OBJECTIVE:

I. To demonstrate improvement in progression free survival (PFS) in the autologous stem cell transplant (ASCT) arm compared to the observation arm.

SECONDARY OBJECTIVES:

I. To assess difference in overall survival (OS) between the observation and autologous stem cell transplant (ASCT) arm.

II. To evaluate the differences in study intervention benefit for PFS and OS by the randomization stratification factors (histology and choice of induction chemotherapy).

III. To evaluate the cumulative incidence of relapse and mortality between the observational and autologous stem cell transplant (ASCT) arm.

EXPLORATORY OBJECTIVE:

I. To determine the impact of minimal residual disease (MRD) on the benefit of autologous stem cell transplant (ASCT).

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive standard of care observation on study. Patients also undergo blood sample collection and optional bone marrow aspiration and biopsy on study, and computed tomography (CT) or positron emission tomography (PET)/CT throughout the study.

ARM II: Patients receive stem cell mobilization and then undergo leukapheresis per standard of care. Patients also receive high dose chemotherapy followed by ASCT per standard of care. Additionally, patients undergo blood sample collection and optional bone marrow aspiration and biopsy on study, and CT or PET/CT throughout the study.

After completion of study treatment, patients are followed up every 3 months for 2 years, every 6 months for 3 years, and then yearly for up to 7 years for a total of 12 years from the date of randomization.

  • Patients with a prior or concurrent whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the regimen are eligible for this trial
  • Patient must not be pregnant or breast-feeding due to the potential harm to an unborn fetus and possible risk for adverse events in nursing infants with the treatment regimens being used. All patients of must have a blood test or urine study within 14 days prior to randomization to rule out pregnancy. A patient of childbearing potential is defined as anyone, regardless of sexual orientation or whether they have undergone tubal ligation, who meets the following criteria: 1) has achieved menarche at some point, 2) has not undergone a hysterectomy or bilateral oophorectomy; or 3) has not been naturally (amenorrhea following cancer therapy does not rule out childbearing potential) for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months)
  • Patient must not expect to conceive or father children by using accepted and effective method(s) of or by abstaining from sexual intercourse during the treatment phase of the study and thereafter according to institutional guidelines

Terms in these criteria, in plain language(17)

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.

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.

Histologically or cytologically confirmed

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Your pathology report is the document that shows this.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

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.

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.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

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.

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.

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.

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.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
