Study summary

The purpose of this study is to assess the safety, pharmacokinetic and activity profiles of the ch14.18 antibody produced in cells of hamster origin (ch14.18/CHO).

Read the detailed description

Anti-ganglioside GD2 antibody ch14.18 is a monoclonal antibody specifically recognizing the target antigen GD2, which is expressed on virtually all neuroblastoma tumours. This antibody is a chimeric protein and consists to 30% of mouse variable light and heavy chain and to 70% of human constant heavy and light chain. Ch 14.18 has already been tested in stage 4 neuroblastoma patients in phase I/II clinical trials with encouraging response rates. Therefore, the European SIOP neuroblastoma group designed a Phase III protocol to test the efficacy of ch14.18 immunotherapy in a randomised trial.

However, the ch14.18 antibody for this Phase III trial was recloned and produced in Chinese hamster ovary (CHO) cells in contrast to ch14.18 antibody used for previous clinical trials, which was produced in murine, non-secreting myeloma cells (SP2/0). Although the antibody-gene transfer into CHO and SP2/0 was done with exactly the same plasmid assuring an identical protein sequence, changes in the glycosylation of the final protein product may occur since the glycosylation pattern varies between different production cell lines. Glycosylation is important for the immunological effector function of the antibody and the pharmacokinetics in patients. Therefore, this change is considered to be a major change in production requiring the reassessment of the new product in a Phase I clinical trial.

The primary objective of this trial is the re-evaluation of toxicity of the new ch14.18/CHO antibody. This is ultimately followed by the secondary objectives including the determination of pharmacokinetics and immunostimulation in patients receiving ch14.18/CHO therapy. This involves particularly the determination of activation of immune effector cells and complement during and after application of ch14.18/CHO. Subsequently, we will evaluate the clinical effect of this treatment on the course of the disease.

The nature of this phase I trial is a bridging study for a medicinal product subjected to a major change in production according to the guidelines provided by the "Committee for Proprietary Medicinal Products" (CPMP) of the "European Agency for the Evaluation of Medicinal Products (EMEA) (Document Number CPMP/BWP/3207/00).

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.

Relapsed and refractory

Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.

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.

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.

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.

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.

FEV1

From a breathing test (spirometry): how much air you can blow out in the first second. Often given as a percentage of what is expected for your age, height and sex.

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.

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).

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.

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.

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.

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.

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.

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.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

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.

Study arms

  • Experimental
    dose level finding ch14.18/CHO

    A dose escalation design based on Phase I rules starting at 10 mg/m2/day ch14.18/CHO. This is 50% below the dose of ch14.18/SP2/0 used in a large cohort of patients. Dose escalation will be adapted to a modified Fibonacci series aiming at 10, 20 and 30 mg/m2 of ch14.18/CHO. Since this study is a bridging study aiming at a reassessment of the toxicity and determination of the pharmacokinetics of ch14.18/CHO, only a limited number of dose escalation steps (3) is implemented in the design.

What researchers measure

Primary outcomes

  1. Adverse events as a measure of safety/tolerability

    Reassess the toxicity profile of one treatment cycle with ch14.18 recloned in CHO cells (ch14.18/CHO), when administered as daily eight-hour infusions and accompanied by supportive care measures in particular to prevent pain, fever and allergic reactions according to previously established standards.

    Time frame: 4 weeks (end of cycle 1)

Secondary outcomes

  1. Measure ch14.18/CHO levels

    Determine the pharmacokinetics of the ch14.18/CHO antibody

  2. Systemic immune modulation

    Determine whether systemic immune modulation results from this therapy using ch14.18/CHO antibody by measuring activation of humoral and cellular immune system.

  3. ch14.18/CHO immunogenicity

    Determine the immunogenicity of ch14.18/CHO antibody by measuring human anti-chimeric humoral immune response.

  4. Anti-tumour response

    Evaluate anti-tumour responses resulting from this treatment regimen through clinical assessments in patients with measurable disease
