Plain English Summary
Background and study aims
Gliomas are the most common type of primary brain tumour, with about 6000 new cases each year in the UK. 1 in 5 patients (20%) with a suspected glioma will present with an epileptic seizure and be treated with an anti-epileptic drug (AED). 4 in 5 patients (80%) do not present with seizures. Up to half of these patients will develop epilepsy requiring AED over their lifetime. Seizures can cause anxiety, loss of independence, affect quality of life & sometimes threaten life. AEDs prevent seizures in 50% of patients with epilepsy and reduce the frequency and severity of seizures in a further 20-30%. Currently, some doctors prescribe AEDs to patients before neurosurgery for tumours, whilst others do not. Researchers need to find out whether AEDs are effective and worthwhile to give the best advice to surgeons and patients in future. Previous studies of AEDs to prevent seizures in patients with a brain tumour have not shown clear results. However, these studies have included tumour types where the risk of seizures is low and they used older AEDs that may interfere with chemotherapy used in brain tumours and have a high risk of side effects. The newer AED, levetiracetam, has fewer side effects and does not interfere with chemotherapy drugs. There is a balance of potential advantages and disadvantages for prescribing levetiracetam. The aim of this study is to find out whether giving patients with a suspected primary brain tumour (cerebral glioma), who have never had a seizure, levetiracetam before surgery to see if it will help prevent them from developing seizures. This will help to give neurosurgeons in the UK the best advice about how to treat patients with a cerebral glioma.
Who can participate?
Patients due to have surgery who have recently been diagnosed with a possible brain tumour, and who have never had an epileptic seizure
What does the study involve?
Participants have a series of tests and examinations to confirm that they are eligible. They are then randomly allocated into two groups. The first group receive levetiracetam daily for 1 year. The second group receive no anti-epileptic drug; this is currently normal practice. Participants are contacted by the trials research nurse monthly by phone to check about any seizures or side effects. If there is a seizure, participants are asked to contact their usual treating team. A neurologist reviews the participant to confirm whether a seizure has occurred. Participants who have a seizure are asked to complete a seizure diary card and questionnaire about the severity of their seizure. All participants are asked to complete questionnaires about their symptoms and possible side effects at entry into the study and every 3 months for a minimum of 1 year. There is no need for any additional blood tests or additional hospital visits. Participants are able to continue on levetiracetam at the end of the study or come off it if they wish.
What are the possible benefits and risks of participating?
It is not known whether there will be a direct benefit to the participants. The researchers hope to be able to find out if taking levetiracetam before surgery will have any effect on delaying, stopping or altering the severity of any seizure that happens after the surgery. Participants taking levetiracetam might expect a lower risk of developing seizures, although the size of this effect is as yet unknown. The results of the trial will hopefully allow the researchers to provide the best advice on preventing seizures in patients with suspected cerebral glioma. A disadvantage of taking part in the study is that participants could experience side effects of levetiracetam. The levetiracetam is given at a lower dose for the first two weeks before increasing to the required dose to help reduce the side effects.
Where is the study run from?
Scottish Clinical Trials Unit, Edinburgh (SCTRU) (UK)
When is the study starting and how long is it expected to run for?
July 2019 and recruitment over 3 years. All patients will be followed up for one year. The information gathered from the trial will be analysed once all patients have been followed up for one year. Where possible patients, who have been in the study for 18 months before the time of analysis, will have a follow up visit at 18 months.
Who is funding the study?
The study is funded by the National Institute for Health Research (NIHR). UCB Pharma, the manufacturer of levetiracetam, have provided this drug free of charge for patients taking part in this study that are allocated to the levetiracetam group

Seizure PRophylaxis IN Glioma (SPRING): a Phase III randomised trial comparing prophylactic Levetiracetam versus no prophylactic antiepileptic drug in patients with newly diagnosed presumed supratentorial glioma
There is no consensus regarding the need for prophylactic AEDs in newly-diagnosed suspected glioma patients who have not experienced seizures. Unfortunately, data regarding prophylactic AED use is scant and inconclusive. Most of the available evidence comes from older, small studies that enrolled patients with brain metastases and benign tumours in addition to gliomas. Furthermore, these studies universally evaluated prophylaxis with first-generation AEDs such as phenytoin, phenobarbital, carbamazepine, and valproic acid. These drugs have higher rates of early adverse effects (such as rash, haematological or liver upset) compared to levetiracetam, and they have important interactions with other drugs including corticosteroids and chemotherapeutics. Levetiracetam is an effective, safe, and well-tolerated medication. It has no known drug interactions and does not require serum level monitoring. It is however frequently associated with fatigue (15%), behavioural problems (13-38%) and problems with aggression. A definitive clinical trial is needed to determine whether the policy of prophylactic levetiracetam therapy reduces the risk of first seizures in this patient population. In addition, evaluation of the impact of levetiracetam on fatigue, behaviour and aggression is needed in this vulnerable population with already high rates of fatigue, cognitive and behavioural problems. There is some evidence that levetiracetam may worsen these symptoms. There is a need to study this area in a well-designed randomised controlled trial.

Patient information sheet
Not available in web format, please use contract details to request a participant information sheet.
After a patient has consented to participate in the study and after ensuring that the patient meets all eligibility criteria, sites will randomise the patient using a web-based randomisation system. This will not be a blinded study and will not have placebo control and as such will be a "real world" study of prophylactic anti-epileptic drug (AED) vs no AED. Patients will be randomised into one of two arms:
Group 1: Levetiracetam 500 mg twice daily for 2 weeks then increasing to 750 mg twice daily thereafter for 1 year. Patients should have a minimum of 2 doses of 500 mg prior to surgery. (In those with moderate chronic kidney disease stage 3 (estimated Glomerular Filtration Rate eGFR 30-59 mL/min/1.73m2) a starting dose of 250 mg twice a day for 2 weeks, then increasing to 500 mg twice a day thereafter).
Group 2: no AED treatment (standard care)
Primary outcome measure
Number of patients developing seizures measured using two-sided type I error level of 5% at 1 year
Secondary outcome measures
1. Time to first seizure measured using accelerated failure time model at 1 year
2. Time to first tonic clonic seizure measured using accelerated failure time model at 1 year
3. Mood, personality, fatigue and memory measured using Mann-Whitney U test (exact method) at 1 year
4. Severity of first seizure should it occur, measured using the LAEP questionnaire at pre surgery (baseline) and 3 monthly to coincide with clinic visits
5. Quality of life, measured using the relative changes in health-related quality of life (HRQoL) resulting from the physical and psychological benefit together with any harms associated with each treatment strategy . This will be administered at pre-surgery (baseline), 3 months, 6 months, 9 months and 12 months post randomisation
6. Progression-free survival determined clinically based upon interpretation of MRI scans, clinical state of the patient and steroid dose at 1 year of randomisation
7. Overall survival measured by using by the median overall survival time for each study arm, tabulated together with the corresponding 80% confidence interval. This will be measured at 1 year of randomisation
8. Costs to the NHS and personal social services (PSS) measured using a within-trial economic analysis which will estimate the incremental cost per quality-adjusted life year (QALY) gained over a 12-month time horizon. The perspective of the analysis (i.e. whose costs and benefits are considered) will be the NHS and personal social services, but the researchers will also take a wider perspective by including costs borne by trial participants, for example out of pocket expenses on health care and the time and travel costs of accessing care. This will be measured over the 12 months trial follow-up
9. Cost-effectiveness of prophylactic levetiracetam measured as incremental cost per QALY at 12 months and modelled over estimated survival

Publication and dissemination plan
The research output of the study will be to inform patients and funders what the benefits and risks are to taking prophylactic AED (levetiracetam) over a one- year period and whether this significantly reduces the chance of having a seizure. It is also likely to give information on the short-term benefits and harms in the first post-operative week (“early seizures”). It will inform the research community what the additional side effects of Levetiracetam are over and above symptoms associated with surgery and radiotherapy. Lastly, although not specifically designed to look at any anti-tumoural effect of levetiracetam, it will give information about whether Levetiracetam improves time to progression or overall survival. As this is the first ever prophylactic AED study in a group of patients at high risk of developing seizures, the result will inform the international research community and may lead to a change in national and international neurosurgical or neuro-oncological guidelines. Exploratory analyses may identify particularly high-risk groups, e.g. cortex or temporal lobe based gliomas, or large mass lesions. The study will be able to determine the cost and cost-effectiveness of prophylactic AED.
Study clinicians will be involved in developing recommendations for practice and policy, based on the results of the SPRING trial. Health service provision/requirements may change. The results will impact on how future clinical trials are designed to ensure acceptability to patients and clinicians. If conclusive the research will change activity by resulting in the routine use, or discontinuation of use of prophylactic AEDs prior to tumour surgery in future, in neurosurgical centres in the UK and possibly beyond. The results may change the attitudes, awareness and behaviour of neurosurgeons in prescribing prophylactic AEDs and increase awareness of potential benefit in less high-risk preoperative patients or potential futility where there has been no benefit in this high-risk group, thereby clarifying the decision making process and standardising practice throughout the NHS. The study is important even if negative, as it will influence practice and provide guidance NOT to give prophylactic levetiracetam.
Beneficiaries will be patients, neurosurgeons, neurologists and oncologists. They will benefit when the study is analysed and ready for presentation at scientific conferences, ideally as late-breaking platform presentations at relevant international meetings. The results will be fully available after the publication of full articles in a journal.
Research will be reported via publication in the NIHR HTA Journal to ensure the research is published fully, with the abstract/full report freely available via the NIHR Journals Library website via Europe PubMed Central. The researchers will prepare for a research Open Access publication in a peer-reviewed journal e.g. Lancet or New England Journal of Medicine.
The research will be disseminated to the wider public as well as research participants by actively involving patients, participating centres, their staff and via presentation at professional UK/international bodies involved in management of patients with brain tumours (Society of British Neuro-Surgery (SBNS); Association of British Neurologists (ABN); Royal College of Radiologists; British Neuro-Onc Society (BNOS). The researchers will use networks of relevant UK charities through regular research updates and annual publications, including the IBTA magazine (13,000 copies sent to recipients in 113 countries and widely distributed at international neuro-onc and cancer conferences).
The PPI panel will develop a dissemination plan so that patients/caregivers understand the findings and can engage confidently with clinicians about the prophylactic use of AEDs. They will write lay summary of findings, create materials for media forms e.g. press releases, blogs, be a voice for the researcher/consumer community, and contribute to the final paper. Presentations with key patient messages will be planned with professional organisations, local health systems. Dissemination methods include podcasts, available through journals (NEJM) and through the SPRING website, linked to NOCTURN (Neuro-Onc Clinical Trials UK Research Network) and SBNS, ABN, BNOS sites.
