Study summary

This phase I trial studies the side effects of nivolumab before and after surgery in treating children and young adults with high grade glioma that has come back (recurrent) or is increasing in scope or severity (progressive). Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

Read the detailed description

PRIMARY OBJECTIVES:

I. To measure the relative changes in cell cycle-related genetic signature of the tumor microenvironment post administration of neoadjuvant nivolumab in children and young adults with recurrent or progressive HGG when compared to a cohort of archived non-treated recurrent pediatric HGG samples.

II. To characterize the safety and tolerability of neoadjuvant nivolumab followed by adjuvant nivolumab in children and young adults with recurrent or progressive HGG.

SECONDARY OBJECTIVES:

I. To determine the 6 month and 12 month overall survival (OS) in children and young adults with recurrent or progressive HGG treated with neoadjuvant nivolumab followed by adjuvant nivolumab.

II. To determine the 6 month and 12 month progression-free survival (PFS) in children and young adults with recurrent or progressive HGG treated with neoadjuvant nivolumab followed by adjuvant nivolumab.

EXPLORATORY OBJECTIVES:

I. To measure relative changes in interferon gamma associated genetic signature within the tumor microenvironment post administration of neoadjuvant nivolumab in children and young adults with recurrent or progressive HGG compared to archived non-treated recurrent pediatric HGG samples.

II. To explore the correlation of interferon-gamma-associated genetic signature, cell cycle-related genetic signature and infiltrating T lymphocyte (TIL) density and clonality with clinical responses.

III. To measure TIL density post administration of neoadjuvant nivolumab in children and young adults with recurrent or progressive HGG.

IV. To estimate the objective response rate (ORR) in children and young adults with recurrent or progressive HGG treated with neoadjuvant nivolumab followed by adjuvant nivolumab.

V. To evaluate the association between advanced MRI parameters (ADC on DWI, rCBV on dynamic susceptibility contrast (DSC) perfusion MRI, pre-contrast T1 shortening on T1-weighed images, and/or MTRasym on pH-Weighted Amine CEST-EPI) and tumor and peripheral blood immune responses.

VI. To measure relative change in peripheral T-cell response and post administration of neo-adjuvant nivolumab in children and young adults with recurrent or progressive HGG.

VII. To measure PD-1 and PDL-1 expression by immunohistochemistry for children and young adults with recurrent or progressive HGG post neoadjuvant nivolumab and evaluate the differences between the treatment cohort and archived non-treated recurrent pediatric HGG samples.

VIII. To explore the correlation of tumor mutational load with clinical response for children and young adults with recurrent or progressive HGG treated with neoadjuvant nivolumab followed by adjuvant nivolumab.

IX. To assess Quality of Life (QOL) and cognitive measures in children and young adults with recurrent or progressive HGG treated with neoadjuvant nivolumab followed by adjuvant nivolumab.

X. To assess patient and/or proxy satisfaction with study participation via patient-reported outcome (PRO) measures in the context of race ethnicity and other health related social risks.

XI. To assess on therapy toxicity in the context of race, ethnicity and other health related social risks.

OUTLINE: Neoadjuvant nivolumab followed by adjuvant nivolumab evaluation.

NEOADJUVANT TREATMENT: Participants will receive a single infusion of nivolumab of 3 mg/kg 14± 5 days prior to surgery. When scheduling, please keep in mind that the two pre-surgical plasma samples (day of neoadjuvant dose and day of surgery) should be drawn greater than 10 days apart.

Tumor samples will be obtained at time of surgery. The tissue from this surgery (fresh, frozen and FFPE) and the archived tissue (FFPE) from the most recent surgery prior to registration revealing HGG will be processed so as to best achieve the primary, secondary and exploratory objectives.

ADJUVANT TREATMENT: Infusion Cycle #1 should begin as soon as participant has recovered from surgery and has been tapered off of steroids. A maximum dexamethasone dose of 0.1 mg/kg/day is allowed, but preferably have been discontinued (inhaled or topical use of steroids is allowed).

Maintenance Cycle 1+ Day 1 \& 15: Participants will receive nivolumab (3mg/kg) IV every 2 weeks until progression or development of unacceptable toxicities or withdrawal. Blood samples will be obtained as pharmacodynamic markers throughout the study (Day 1 of every other cycle). Dose interruptions and symptomatic management will occur based upon preset adverse event determination.

After completion of study treatment, patients are followed up at 30 days and then every 2 months for up to 5 years.

Terms in these criteria, in plain language(26)

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.

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.

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.

Line of therapy

A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.

“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.

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.

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.

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.

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.

PD-1, PD-L1 and checkpoint inhibitors

PD-1, PD-L1 and CTLA-4 are proteins that act as brakes on the immune system. Checkpoint inhibitors, such as pembrolizumab or nivolumab, block them so the immune system can attack a cancer.

PD-L1 can also be measured in a tumour sample. Some scores count stained tumour cells only (TPS); others also count certain immune cells (CPS). The study names the score and the minimum it uses.

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.

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.

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.

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.

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.

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.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

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.

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.

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.

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. Percentage change in cell cycle-related genetic signature

    Will assess the percentage change in cell cycle-related genetic signature post administration of neoadjuvant treatments when compared to archived recurrent pediatric HGG group. The number of participants with high cell cycle gene signature (positive median gene set variation analysis (GSVA) score) will be tabulated. Variables involved in the primary analyses will be examined graphically and summarized by descriptive statistics.

    Time frame: From screening to surgery visit (neoadjuvant treatment groups); at time of recurrent high grade glioma (HGG) tissue collection (for archived non-treated samples)

  2. Proportion of participants with treatment-related adverse events

    Adverse events will be monitored throughout the trial and graded in severity according to the guidelines outlined in the National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0 from initiation of study treatment until 2 years after treatment discontinuation or until study treatment related adverse events resolve or return to baseline, Adverse experiences (specific terms as well as system organ class terms) and predefined limits of change in laboratory, and vital sign parameters that are not pre-specified as events of interest will be summarized with descriptive statistics (counts, percentage, mean, standard deviation, etc.).

    Time frame: Up to 2 years

Secondary outcomes

  1. Overall survival

    Survival will be assessed at 6 months and 12 months from the time of enrollment until the time of death. Kaplan-Meier survival analyses will be performed. Medians together with 2-sided 95% confidence intervals will be computed using a log-log transformation.

    Time frame: Up to 12 months

  2. Progression-free survival (PFS)

    PFS is defined as the time of enrollment until the time of progressive disease or death. Kaplan-Meier survival analyses will be performed. Medians together with 2-sided 95% confidence intervals will be computed using a log-log transformation.

    Time frame: Up to 12 months

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.
