Study summary

The purpose of this research study is to determine whether taking either of two low dose drugs that would prevent new blood vessels from growing after stem cell transplant is feasible, and what the side effects of taking each of these drugs after autologous transplant might be. The reason the investigators are looking at these drugs is because one of the things that allows tumors to grow quickly is their ability to stimulate the growth of new blood vessels. By suppressing the growth of new blood vessels after stem cell transplant, the investigators hope to prevent the tumors from coming back or continuing to grow.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Patient must have an original diagnosis, benefited by transplantation, confirmed by * of high-grade glial tumor, low-grade glial tumor, ependymoma, medulloblastoma, primitive neuro-ectodermal tumor (PNET), Wilms' tumor, rhabdomyosarcoma, Ewing's sarcoma, retinoblastoma, or miscellaneous poor-prognosis solid tumors. Lymphomas and other lymphoid will not be studied in this protocol.

    * Brain stem glioma patients who have progressed after radiation therapy do not require histologic confirmation. Brain stem gliomas are defined as intrinsic tumors of the pons causing diffuse enlargement. These patients are diagnosed on clinical and radiographic appearance of the lesion and the biopsy requirement will be waived for this group.

  • Patient must be ≥ 6 months of age and ≤ 21 years of age at the time of study entry.
  • Patient must have a performance status or Lansky* play status ≥ 50

    * For purpose of determining performance scores, wheelchair-bound patients will be considered ambulatory.

  • Patient must have an adequate supply of stem cells for transplant harvested prior to study enrollment, with adequate supply defined as 3 x 10\^6 CD34+ cells/kg for peripheral blood stem cells (PBSC). Cell mobilization method will be left up to the treating physician's discretion and may include mobilization growth factor alone or mobilization after chemotherapy. If patient is unable to mobilize the proper amount of peripheral stem cells, bone marrow may be harvested as the source of hematopoietic stem cells. In this instance, 3 x 10\^8 mononuclear cells/kg will be considered adequate. If necessary, a combination of peripheral stem cells and bone marrow can be used.
  • Prior radiation therapy and/or chemotherapy, including cyclophosphamide, are permitted.
  • Prior anti-angiogenic therapy, including thalidomide and oral cyclophosphamide, is permitted.
  • If on for mass effect and/or edema related to the tumor, patient must be on a stable or decreasing dose for at least 2 weeks prior to study entry.
  • Patient must have a > 3 months.
  • Patient must have an adequate bone marrow reserve as defined by:

    • ≥ 8.0 g/dl and
    • Peripheral (ANC) ≥ 750/mm3
  • Patient must have adequate cardiac function tested within 4 weeks of study enrollment as defined by:

    • Shortening fraction of ≥ 27% by echocardiogram or
    • of ≥ 50% by radionuclide angiogram
  • Patient must have adequate pulmonary function tested within 4 weeks of study enrollment as defined by:

    • Pulse oximetry > 94% on room air or O2 by nasal cannula and
    • No evidence of dyspnea at rest.
  • Patient must have adequate hepatic function as defined by:

    • Total ≤ 1.5x (ULN) for age and
    • (AST) or SGPT (ALT) ≤ 2.5 x ULN (SGOT ≤ 4x ULN if on Zantac)
  • Patient must have adequate renal function as defined by:

    • Serum creatinine \< 1.5 mg/dl
    • (GFR), calculated via I-125 iothalamate clearance, 24-hour , or Schwartz formula*, ≥ 70 mL/min and ≥ 50 mL/min/1.73 m2 done within 4 weeks of study entry
    • The Schwartz formula is an estimated glomerular filtration rate in children based upon serum creatinine and height. Height (Ht) should be measured in cm and serum creatinine (Cr) in mg/dL. Proportionality constant (k) is 0.55 for children and adolescent girls and 0.7 for adolescent boys aged 13-21. This constant is based upon a series of evaluations performed by Schwartz. Formula: GFR= (k x Ht)/Cr
  • Enrollment in the Celgene THALOMID REMSTM Program:

    1. If enrolled in Arm III of this study, patient must be registered at the Celgene THALOMID REMSTM Program prior to day +30 post-ASCR.
    2. If enrolled in Arm III of this study, patient must be willing to practice as outlined in the THALOMID REMSTM Program from the beginning of the thalidomide treatment until at least 4 weeks following discontinuation of thalidomide therapy. Two reliable forms of contraception must be used simultaneously unless continuous abstinence from heterosexual sexual contact is chosen. Contraceptive methods must include at least one highly effective method (e.g. oral contraceptive pills, injections, hormonal patches, IUD, or implants), AND one additional effective barrier method (e.g. latex condom, diaphragm, cervical cap).

      If hormonal or IUD contraception is medically , another highly effective method or two barrier methods must be used at the same time.

    3. Pregnancy surveillance:

    i. Patient must have a negative in office pregnancy test sensitive to within 50 mIU/mL (serum or urine) within 24 hours prior to beginning thalidomide even if continuous abstinence is the preferred method of birth control. ii. A pregnancy test must be performed weekly during the first 4 weeks of therapy and repeated monthly for patients with regular menses or every 2 weeks for patients with irregular menses iii. Negative pregnancy tests are valid for only 7 days. iv. If irregular bleeding or skipped menses, pregnancy test should be performed and pregnancy counseling given. v. If pregnancy occurs during treatment, thalidomide must be immediately discontinued. Any suspected lethal exposure must be reported immediately to Celgene Customer Care Center at 1-888-423-5346, and the patient referred to an OB/GYN experienced in reproductive toxicity for further evaluation and counseling.

  • Patient (or legally authorized representative) must be able to understand and willing to sign a written document.

Exclusion criteria

Exclusion Criteria:

  • Patient must not have any active, uncontrolled cardiac, hepatic, renal, or psychiatric disease defined as ≥ grade 3 based on NCI v4.0 (CTCAE).
  • Patient must not be receiving any other agents.
  • Patient must not have any active infection or concurrent illness obscuring toxicity or dangerously altering drug metabolism.
  • Patient must not have any thromboembolic event (deep vein thrombosis or pulmonary embolism) less than 3 weeks prior to enrollment.
  • Patient must not have a history of allergic reactions attributed to compounds of similar chemical or biologic composition to any of the agents used in the study.
  • Patient must not be pregnant or breastfeeding.
Terms in these criteria, in plain language(19)

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.

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.

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.

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.

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.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

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.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

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.

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.

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.

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.

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.

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.

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.

CTCAE grade

The US National Cancer Institute’s scale of how severe an adverse event is — any unwanted medical event during a study, such as a symptom, an illness or an abnormal test result, whether or not a treatment caused it. Whether it did is judged separately.

1
Mild.
2
Moderate.
3
Severe.
4
Life-threatening.
5
Death due to the event.

“Side effects of earlier treatment resolved to grade 1 or less” means they have settled to mild or gone.

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.

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Oct 2012 to primary completion in Dec 2023, 134 months.

Of 166 non-industry phase 1 interventional studies under Glioma, half reached primary completion within 59 months of starting (the median), counting those still running; a quarter within 36 and three quarters within 87. This study's 134 months is above that.

Counting every sponsor, half of 213 studies reached it within 59 months; a quarter within 36 and three quarters within 88.

How these figures are worked out, and which studies are left out of them.

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.
