Study summary

This phase I trial studies the side effects and best dose of lenalidomide when given together with usual combination chemotherapy (etoposide, prednisone, vincristine sulfate [Oncovin], cyclophosphamide, and doxorubicin hydrochloride [hydroxydaunorubicin hydrochloride], or "EPOCH") in treating adult T-cell leukemia-lymphoma. Lenalidomide may help shrink or slow the growth of adult T-cell leukemia-lymphoma. Drugs used in chemotherapy, such as etoposide, vincristine, cyclophosphamide, and doxorubicin, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Anti-inflammatory drugs such as prednisone lower the body's immune response and are used with other drugs in the treatment of some types of cancer. Giving lenalidomide and the usual combination chemotherapy may work better in treating adult T-cell leukemia-lymphoma compared to the usual combination chemotherapy alone.

Read the detailed description

PRIMARY OBJECTIVE:

I. To determine the safest and most tolerable dose and schedule of lenalidomide to combine with etoposide, prednisone, vincristine sulfate (Oncovin), cyclophosphamide, and doxorubicin hydrochloride (hydroxydaunorubicin hydrochloride) (EPOCH) chemotherapy in adult T-cell leukemia-lymphoma (ATL/ATLL).

SECONDARY OBJECTIVES:

I. To observe and record anti-tumor activity. II. To determine if lenalidomide and EPOCH activity results in significant improvement in remission rates, duration of remissions, and overall survival (OS) as compared to historical controls.

III. To determine if lenalidomide and EPOCH activity correlates with T-cell receptor (TCR) pathway gene mutational spectrum.

IV. To determine effects of lenalidomide and EPOCH on human T-cell leukemia virus type 1 (HTLV-1) proviral deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) loads.

V. To determine effects of lenalidomide and EPOCH on HTLV-1 clonality.

OUTLINE: This is a dose-escalation study of lenalidomide followed by a dose-expansion study.

INDUCTION THERAPY: Patients receive lenalidomide orally (PO) once daily (QD) on days 1-14 of 21 day cycles or days 1-21 or 1-28 of 28 day cycles. Patients receive doxorubicin hydrochloride intravenously (IV) continuously on days 1-4, vincristine sulfate IV continuously on days 1-4, etoposide IV continuously on days 1-4, prednisone PO on days 1-5, and cyclophosphamide IV over 1-4 hours on day 5. Treatment repeats every 21 or 28 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity.

MAINTENANCE THERAPY: Patients with complete response (CR), partial response (PR), or stable disease (SD) may receive up to 2 additional cycles of lenalidomide, doxorubicin hydrochloride, vincristine sulfate, etoposide, prednisone, and cyclophosphamide at the discretion of the investigator and/or up to an additional 2 years of lenalidomide in the absence of disease progression or unacceptable toxicity.

Patients undergo bone marrow biopsy at baseline and as clinically indicated. Patients undergo positron emission tomography/computed tomography (PET/CT) or CT, tissue and blood sample collection throughout the trial and multigated acquistion scan (MUGA) and echocardiogram (ECHO) at screening.

After completion of study treatment, patients are followed up for 2 years from end of induction. Patients who do not continue on lenalidomide maintenance are followed every 3 months for up to 2 years from the end of induction, progression, withdrawal, or until death, whichever occurs first.

Exclusion criteria

Exclusion Criteria:

  • Patients that have received prior IMiDs for treatment of ATLL
  • Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study
  • Patients who have not recovered to grade 1 or better from AEs due to prior anti-cancer therapy (not including cycle 1 of EPOCH, CHOP, or CHOPE if received off protocol) within 14 days prior to enrollment, with the exception of alopecia
  • Patients who are receiving any other agents or have received them within 14 days prior to enrollment
  • History of allergic reactions attributed to compounds of similar chemical or biologic composition to lenalidomide or other agents used in study. Anaphylactic reactions including death have been reported with cyclophosphamide. Possible cross-sensitivity with other alkylating agents can occur
  • Patients unable to take aspirin or prophylactic doses of low molecular weight heparin or direct oral anticoagulants
  • Patients with urinary outflow obstruction ( for cyclophosphamide)
  • Patients with any form of demyelinating disease should not be given vincristine sulfate injection
  • Patients with uncontrolled intercurrent illness
  • Patients with psychiatric illness/social situations that would limit compliance with study requirements
  • Pregnant women are excluded from this study because lenalidomide is an IMiD agent with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with lenalidomide, breastfeeding should be discontinued if the mother is treated with lenalidomide. These potential risks may also apply to other agents used in this study
Terms in these criteria, in plain language(22)

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.

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.

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.

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.

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.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

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.

Brain metastases

Cancer deposits in the brain from a cancer that started elsewhere in the body (CNS metastases include the spinal cord).

Studies differ: some leave out any brain metastases, some accept ones treated and stable for some weeks. Check what this study allows.

Leptomeningeal disease

Cancer that has spread to the leptomeninges, the thin layers covering the brain and spinal cord, and the fluid between them. It is not the same as brain metastases.

Criteria often treat it separately, and many studies leave it out even where treated brain metastases are allowed.

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.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

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.

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.

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.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

What researchers measure

Primary outcomes

  1. Maximum tolerated dose (MTD)

    Will determine the MTD for lenalidomide in combination with etoposide, prednisone, vincristine sulfate (Oncovin), cyclophosphamide, and doxorubicin hydrochloride (hydroxydaunorubicin hydrochloride) (EPOCH) chemotherapy.

    Time frame: Up to the end of induction therapy

Secondary outcomes

  1. Overall response rate

    Will be summarized using descriptive statistics. Binomial proportions and their 95% confidence intervals will be used to estimate the response rates of therapy.

    Time frame: Up to 2 years after completion of study treatment

  2. Duration of response

    Will be summarized using descriptive statistics. The Kaplan-Meier method will be used to evaluate the response duration.

    Time frame: From the time measurement criteria are met for complete response or partial response until the first date that recurrent or progressive disease is objectively documented, assessed up to 2 years after completion of study treatment

  3. Progression-free survival

    Profession-free survival will be determined by the number of weeks from the time of initiation of therapy until there is evidence of tumor progression by acute T-cell leukemia (ATL) response criteria of Tuskasaki, 2009.

    Time frame: Up to 2 years after completion of study treatment

  4. Overall survival

    Over survival will be determined by the number of week of weeks from the time of initiation of therapy until death.

    Time frame: Up to 2 years after completion of study treatment

  5. T-cell receptor pathway gene mutational spectrum

    T-cell receptor pathway gene mutation will be determined by targeted next-generation sequence after hybridization to specific oligonucleotide capture probes corresponding to the sequence most commonly mutation in ATL as defined by Kataoka et al, 2015.

    Time frame: Up to 2 years after completion of study treatment

  6. Human T-cell leukemia virus type 1 (HTLV-1) proviral deoxyribonucleic acid and ribonucleic acid loads

    Analysis of variance methods will be used to evaluate the effects of treatment and time on the viral load measurements, as well as measurements of viral transcripts.

    Time frame: Up to 2 years after completion of study treatment

  7. HTLV-1 clonality

    HTLV-1 clonality will be determined by next generation sequence analysis of viral integration sites resulting in a distribution of the number of reads for each integration site plotted per integration site, as described by Gillet et al. 2011.

    Time frame: Up to 2 years after completion of study treatment

  8. Incidence of toxicities

    The incidence of toxicities will be estimated using the binomial proportion and its 95% confidence interval.

    Time frame: Up to the end of induction therapy
