Summary

Oligodendrogliomas in the novel edition of the Central Nervous System (CNS) World Health Organization (WHO) classification are now molecularly defined by isocitrate dehydrogenase (IDH)1 or IDH2 mutations and 1p/19q co-deletion. The prognosis of these molecularly defined tumors is to be determined in new series since survival data from older histology-based studies and population-based registries are confounded by the inclusion of 20-70% not molecularly matching subsets. Also, the optimal treatment is a matter of ongoing investigations. An extensive, but safe surgery is associated with improved outcome as is the addition of chemotherapy with procarbazine, CCNU (lomustine), and vincristine (PCV) to the partial brain radiotherapy (RT). However, the exact timing of postsurgical therapy especially for tumors of the WHO grade II and acknowledging some variability in grading as well as the choice of chemotherapy, temozolomide instead of PCV (CODEL: NCT00887146 randomizing CNS WHO grade 2 and 3 oligodendrogliomas to chemoradiation(CHRT)therapy with PCV or with temozolomide) or the need for primary radiotherapy RT are subjects of clinical studies (POLCA: NCT02444000 randomizing patients with newly diagnosed CNS WHO grade 3 oligodendrogliomas to standard CHRT with PCV or PCV alone). Given the young age of patients with CNS WHO grade 2 and 3 oligodendrogliomas and the relevant risk of neurocognitive, functional and quality-of-life impairment with the current aggressive standard of care treatment, chemoradiation with PCV, of the tumor located in the brain optimizing care is the major challenge.

NOA-18/IMPROVE CODEL aims at improving qualified overall survival (qOS) for adult patients with CNS WHO grade 2 and 3 oligodendrogliomas by randomizing between standard chemoradiation with up to six six-weekly cycles with PCV and six six-weekly cycles with lomustine and temozolomide (CETEG), thereby delaying radiotherapy (RT) and adding the chemoradiotherapy (CHRT) concept at progression after initial radiation-free chemotherapy, allowing for an effective salvage treatment and delaying potentially deleterious side effects. QOS represents a new concept and is defined as OS without functional and/or cognitive and/or quality of life (QOL) deterioration regardless whether tumor progression or toxicity is the main cause.

Description

The primary objective of the NOA-18/IMPROVE CODEL trail is to show superiority of an initial CETEG treatment followed by partial brain radiotherapy (RT) plus PCV (RT-PCV) at progression over partial brain radiotherapy (RT) followed by procarbazine, lomustine and vincristine (PCV) chemotherapy (RT-PCV) and best investigators choice (BIC) at progression for sustained qOS. An event with respect to a sustained qOS is then defined as a functional and/or cognitive deterioration on two consecutive study visits with an interval of 3 months, tolerating a deviation of at most 1 month. Assessments are done with 3-monthly MRI, assessment of the NANO (Neurologic assessment in neuro-oncology) scale, HRQoL, and KPS (Karnofsky performance status) and annually cognitive testing. Secondary objectives are evaluation and comparison of the two groups regarding secondary endpoints (short-term qOS, PFS, OS, complete and partial response rate). The trial is planned to be conducted at 21 NOA (Neurooncology Working Party of the German Cancer Society) study sites in Germany.

Tumor carries an isocitrate dehydrogenase (IDH) mutation (determined by immunohistochemistry (IHC) and/or deoxyribonucleic acid (DNA) sequencing)
Tumor is co-deleted for 1p/19q (determined by copy number variations, fluorescence in situ hybridization (FISH), multiplex ligation-dependent probe amplification (MLPA) or other appropriate methods)
Open biopsy or resection
Age ≥18 years
Karnofsky Performance Index (KPI) ≥60%
Life expectancy > 6 months
Availability of formalin-fixed paraffin-embedded (FFPE) or fresh-frozen tissue and ethylenediamine tetraacetic acid (EDTA) blood for biomarker research
Standard magnetic resonance imaging (MRI) ≤ 72 post-surgery according to the present national and international guidelines
Craniotomy or intracranial biopsy site must be adequately healed
≥ 2 weeks and ≤ 3 months from surgery without any interim radio- or chemotherapy or experimental intervention
Willing and able to comply with regular neurocognitive and health-related quality of life tests/questionnaires
Indication for postsurgical cytostatic/-toxic therapy
Written Informed consent
Female patients with reproductive potential have a negative pregnancy test (serum or urine) within 6 days prior to start of therapy. Female patients are surgically sterile or agree to use adequate contraception during the period of therapy and 6 months after the end of study treatment, or women have been postmenopausal for at least 2 years
Male patients are willing to use contraception

Exclusion Criteria

Participation in other ongoing interventional clinical trials
Insufficient tumor material for molecular diagnostics
Inability to undergo MRI
Abnormal (≥ Grade 2 CTCAE v5.0) laboratory values for hematology (Hb, WBC (White Blood Cell), neutrophils, or platelets), liver (serum bilirubin, ALT (Alanine Amino Transferase), or AST (Aspartate Amino Transferase)) or renal function (serum creatinine)
Active tuberculosis; known HIV infection or active Hepatitis B (HBV) or Hepatitis C (HCV infection, or active infections requiring oral or intravenous antibiotics or that can cause a severe disease and pose a severe danger to lab personnel working on patients' blood or tissue (e.g. rabies)
Any prior anti-cancer therapy or co-administration of anti-cancer therapies other than those administered/allowed in this study. History of low-grade glioma that did not require prior treatment with chemotherapy or radiotherapy is not an exclusion criterion

Any clinically significant concomitant disease (including hereditary fructose intolerance) or condition that could interfere with, or for which the treatment might interfere with, the conduct of the study or the absorption of oral medications or that would, in the opinion of the Principal Investigator, pose an unacceptable risk to the patient in this study
Any psychological, familial, sociological, or geographical condition potentially hampering compliance with the study protocol requirements and/or follow-up procedures; those conditions should be discussed with the patient before trial entry
