Studien-Informationen

Detailed Description:

The Ependymoma Program is a comprehensive program to improve the accuracy of the primary

diagnosis of ependymoma and explore different therapeutic strategies in children, adolescents

and young adults, accordingly. This program is opened to all patients diagnosed with

ependymoma below the age of 22 years.

It will include a centralised review of pre and post-operative imaging to assess the

completeness of the resection.

It will also include a central review of pathology to confirm the histological diagnosis. The

biological markers 1q and 6q gain, Tenascin C status, NELL2 and LAMA2, RELA-fusion and

molecular subgroup by methylation array will be prospectively assessed for prospective

evaluation of disease subgroups. Further biological evaluations will be coordinated within

the linked BIOMECA study.

After surgery and central review of imaging and pathology, patients will be offered the

opportunity to undergo second look surgery, if possible. Patients will be enrolled in one of

3 different strata according to the outcome of the initial surgical resection (residual

disease vs no residual disease), their age or eligibility / suitability to receive

radiotherapy. These 3 different strata correspond to 3 therapeutic strategies according to

the patient status.

1. Stratum 1 is designed as a randomised phase III study for patients who have had a

complete resection, with no measurable residual disease (as confirmed by centrally

reviewed MRI) and are > 12 months and < 22 years at diagnosis. Those patients will be

randomised to receive conformal radiotherapy followed by either 16 weeks of chemotherapy

with VEC-CDDP, or observation.

2. Stratum 2 is designed as a randomised phase II study for patients who have inoperable

measurable residual disease and who are > 12 months and < 22 years at diagnosis. Those

patients will be randomised to two different treatment schedules of chemotherapy either

with VEC or VEC+ high dose methotrexate (VEC +HD-MTX). After completion of the frontline

chemotherapy, patients will be assessed for response (MRI) and will receive second look

surgery when feasible. For those patients who remain unresectable with residual disease

despite frontline chemotherapy and for whom second line surgery is not feasible, there

will be a study of the safety of a radiotherapy boost of 8 Gy that will be administered

to the residual tumour immediately after the completion of the conformal radiotherapy.

Patients without evidence of residual disease after the chemotherapy and/or a second

look surgery are not eligible for radiotherapy boost. All patients who have not shown

progression under chemotherapy will receive, as maintenance therapy, a 16 week course of

VEC -CDDP following completion of radiotherapy.

3. Stratum 3 is designed as a randomised phase II chemotherapy study in children <12 months

of age or those not eligible to receive radiotherapy. These patients will be randomised

to receive a dose dense chemotherapy alternating myelosuppressive and relatively

non-myelosuppressive drugs at 2 weekly intervals, with or without, the addition of the

histone deacetylase inhibitor, valproate.

Registry: Patients that do not fulfil the inclusion criteria of one of the interventional

strata will be enrolled and followed up via an observational study which will be analysed

descriptively.

Ein-/Ausschlusskriterien

After Initial surgery, patients will be enrolled in one of 3 different interventional

strata where they will be offered a set of therapeutic interventions based on the outcome

of the intervention (no measurable residue vs residual inoperable disease), their age

and/or their eligibility /suitability to receive radiotherapy.

Patients with centrally and histologically confirmed intracranial ependymoma meeting the

following criteria will be enrolled into one of interventional stratum:

- Age < 22 years old at diagnosis

- Newly diagnosed intracranial ependymoma of WHO grade II-III confirmed by central

pathological review

- Post-menarchal female not pregnant or nursing (breast feeding) and with a negative

beta-HCG pregnancy test prior to commencing the trial

- Males and females of reproductive age and childbearing potential with effective

contraception for the duration of their treatment and 6 months after the completion of

their treatment

- No contraindication to the use if one of the study drugs proposed by the protocol

- Patients and/or their parents or legal guardians willing and able to comply with

scheduled visits, treatment plan, laboratory tests and other study procedure

- No co-existent unrelated disease at the time of study entry that would render the

patient unable to receive chemotherapy

- No signs of infection.

Common inclusion criteria for Strata 1 and 2:

- Age > 12 months and < 22 years at time of study entry

- No metastasis on spinal MRI and on CSF cytology assessments

- No previous radiotherapy

- No previous chemotherapy (except steroids)

- No medical contraindication to radiotherapy and chemotherapy

- Adequate bone marrow, liver and renal functions

Specific inclusion criteria for Stratum 1:

• No residual measurable ependymoma based on the central neuroradiological review (R0-1-2)

Specific inclusion criteria for Stratum 2:

• Residual non reoperable measurable ependymoma based on the central neuroradiological

review (R3-4)

Inclusion criteria for Stratum 3:

- Children younger than 12 months at time of entry to study or any children ineligible

to receive radiotherapy due to age at diagnosis, tumour location or clinician / parent

decision and according to national criteria

- Adequate bone marrow, liver and renal functions

- No previous chemotherapy and radiotherapy

- No contraindication to chemotherapy Patients that do not fulfill the inclusion

criteria of one of the interventional strata will be enrolled and followed up into an

observational study and descriptive analysis will be performed.

EXCLUSION CRITERIA for all interventional strata:

- Pre-existing severe hepatic and/or renal damage

- Family history of severe epilepsy

- Presence of previously undiagnosed mitochondrial disorder detected by screening as

part of trial

- Elevated blood ammonium and lactate level ≥ 1.5 x upper limit of the normal
