Protocol summary 
Title of the Study 
Trabectedin for recurrent grade II or III meningioma: a randomized phase II 
study of the EORTC Brain Tumor Group 
Objective(s) 
The aim of this randomized phase II study is to collect data on activity, 
safety and quality of life of trabectedin therapy in patients with recurrent 
high-grade meningioma.  
Methodology 
Phase II, 2:1 randomization, Korn design 
Number of patients  
Number planed 
(Statistical design) 
Number analyzed 
Total number of patients: 86 eligible patients who started allocated 
treatment (57 in the experimental arm, 29 in the control arm). 
With 2:1 randomization and assuming 6-month progression-free survival 
(PFS-6)=15% in the control and 35% in the trabectedin arm, assuming PFS 
follows an exponential distribution, Hazard Ratio (HR)=0.55, one-sided 
logrank test, at alpha=10% (20% two sided), power=85%, 72 progression 
or death events are needed to assess the targeted effect. 86 eligible patients 
who started allocated treatment will be analyzed (57 trabectedin, 29 
control). Assuming an accrual of 7.17 patients per month (1.99 months 0-4, 
3.55 months 4-8, 5.29 months 8-12 and 7.17 beyond 12 months), about 18 
months of recruitment are needed.  
Diagnosis and 
main criteria for 
inclusion

♦ Histological diagnosis of WHO grade II (chordoid meningioma, clear 
cell meningioma, atypical meningioma) or WHO grade III (papillary 
meningioma, rhabdoid meningioma, anaplastic/malignant meningioma) 
according to WHO 2007 classification. 
♦ Radiologically documented progression of any existing tumor (growth 
> 25% in the last year) or appearance of new lesions (including intra- 
and extracranial manifestations) 
♦ No more option for local therapy (resection or radiotherapy) after 
maximal feasible surgery and radiotherapy

♦ No serious illness or medical conditions, specifically: active infectious 
process; chronic active liver disease, including chronic hepatitis B, C or 
cirrhosis 
♦ No concomitant use of any other investigational agent, phenytoin, or 
vaccination to yellow fever. 
♦ Women of child bearing potential (WOCBP) must have a negative 
serum (or urine) pregnancy test within 72 hours prior to randomization 
(and again within 72 hours prior to the first dose of study treatment). 
Patients of childbearing / reproductive potential should use adequate 
birth control measures, as defined below, during the study treatment 
period and for at least 3 months after the last study treatment. Men who 
are fertile must use effective contraception during treatment with 
trabectedin and for 5 months thereafter.  
Methods that can achieve a failure rate of less than 1% per year when 
used consistently and correctly are considered as highly effective birth 
control methods. Such methods include: 
♦ combined (estrogen and progestogen containing) hormonal 
contraception associated with inhibition of ovulation: 
♦ oral 
♦ intravaginal

of ovulation: 
♦ oral 
♦ injectable 
♦ implantable 
♦ intrauterine device (IUD) 
♦ intrauterine hormone-releasing system ( IUS) 
♦ bilateral tubal occlusion 
♦ vasectomised partner

the ingredients of the trabectedin solution for infusion 
♦ No known MRI or CT, including contrast media, contraindications 
♦ Absence of any psychological, familial, sociological or geographical 
condition potentially hampering compliance with the study protocol and 
follow-up schedule; those conditions should be discussed with the 
patient before registration in the trial 
♦ Before patient randomization, written informed consent must be given 
according to ICH/GCP, and national/local regulations. 
Treatment 
Test product, dose 
and mode of 
administration 
Trabectedin will be delivered as a 24-hour infusion every 3 weeks (day 1 of 
each 21-day cycle) at a starting dose of 1.5 mg/m2 BSA. Administration 
through a central venous line is strongly recommended. Subjects receiving 
trabectedin are required to receive dexamethasone pretreatment at 20 mg 
IV, 30 minutes before starting trabectedin.  
Duration of 
treatment 
Until progression or unacceptable toxicity or patients' refusal.

Primary end-point:  
Progression Free Survival (PFS) 
Secondary end-points: 
♦ Progression Free Survival at 6 months (PFS-6), median PFS (mPFS) 
♦ Best overall response (BOR). Objective response (CR/PR), rate and 
median duration. Complete response (CR), rate and median duration.  
♦ Overall survival (OS), OS probability at 6 (OS6) and 12 months 
(OS12), median OS (mOS) 
♦ Safety (CTCAE v.4.0) 
♦ Health-related Quality of life (HRQol) 
Statistical methods 
The primary endpoint, PFS, will be compared between the trabectedin and 
the control arm when 71 PFS events are observed. A Cox regression model 
adjusted by stratification factors at randomization (except institution) will 
be fit. If Proportional Hazards assumptions (PH) are not respected (as 
assessed by Schoenfeld residuals) for a particular factor, the model will be 
stratified and not adjusted by this factor. The superiority of trabectedin 
against the control arm will be tested at 10% one-sided (20% two-sided) 
significance level. The treatment Hazard Ratio (HR) estimate will be 
presented with 90% one-sided confidence interval (CI). 95% CI will also be 
presented. The PFS-6 and the mPFS will be extracted from the Kaplan-
Meyer PFS curve. 95% confidence intervals will be computed based on the 
Greenwood's formula. For the median the Reflected Method will provide 
95% confidence intervals.

Translational 
research 
Formalin-fixed, paraffin-embedded (FFPE) blocks of tumor samples will be 
collected for retrospective central pathology review. In addition, the 
association of tumor proliferation, microvascular density, and density of 
tumor-associated macrophages with response to treatment will be explored 
using immunohistochemistry. In addition, the full landscape of potential 
diagnostic, prognostic and predictive molecular markers within the tumor 
samples will be profiled by means of next-generation-sequencing and the 
Illumina 850k methylation assay. 
Retrospective review of the images will take place for this study. Although 
treatment decisions are based on objective tumor assessment at the treating 
sites, retrospective central review will reassess all images to confirm the 
initial assessment. 
Retrospective studies have indicated that systemic therapy may decrease 
the growth rate of meningiomas. MRI scans acquired up to 2 years before 
inclusion of patients into the EORTC-1320 trial will be collected to 
investigate whether the growth dynamics of grade II or III meningiomas 
changes with start of study treatment. 
Preliminary response assessment in neuro-oncology (RANO) criteria for 
response assessment in meningioma were presented in the RANO working 
group meeting during the 2014 ASCO annual meeting. Publication is 
expected. 2D and volumetric measurements will be obtained through 
retrospective imaging review, aiming to add information towards validation 
of the RANO response assessment criteria for meningioma. 
Quality of Life 
The main objective of HRQoL assessment within this trial is to determine 
the impact of trabectedin on seven chosen domains being primarily global 
QoL, with role functioning, physical functioning, cognitive functioning, 
fatigue, diarrhea, and nausea and vomiting as secondary key issues, both 
during and after treatment. A secondary objective is to evaluate the effect 
of the treatment on the remaining symptoms and functioning scales as 
treatment-related side effects may have a (temporary) negative influence on 
the health related domains of HRQoL of these patients. HRQoL will be 
measured using the QLQ-C30 (v3) and the BN-20 module.

1 Background and introduction 
1.1 
Meningioma 
Meningiomas account for about 24-30% of primary intracranial tumors and occur at an annual incidence 
rate of up to 13 per 100 000. Most meningiomas are benign (WHO grade I) and curable by resection. 
However, up to 20% of meningiomas show aggressive behavior with tumor recurrences and infiltration of 
the surrounding tissues (bone, brain, or soft tissue). WHO grade II (chordoid, clear cell, atypical) and 
WHO grade III (papillary, rhabdoid, anaplastic/malignant) meningiomas are characterized 
histopathologically by increased numbers of mitotic features, and have increased risk for unfavorable 
clinical course.  
Owing to the rarity of aggressive meningiomas, there is lack of evidence from systematic studies to guide 
treatment. Until now, maximal resection and postoperative radiotherapy have emerged as the most 
commonly used therapy for WHO grade II and III meningiomas. For recurrent disease, there are few 
therapy options. Repeated surgery or radiotherapy may achieve local tumor control in some patients. 
Medical therapy of recurrent high-grade meningioma is challenging, as no standards are defined. Recently, 
the RANO group has summarized and reviewed outcome data for surgery- and radiotherapy-refractory 
WHO II and III meningiomas (Ref. 1). Disease stabilization was reported for a number of agents including 
hydroxyurea, CAV chemotherapy (cyclophosphamide, doxorubicin, and vincristine), interferon-alpha, 
octreotide, Sandostatin LAR, erlotinib, vatalinib, sunitinib and bevacizumab (Ref. 1). However, these data 
come only from small case series and no randomized studies are available. Reported median progression-
free survival times and overall survival times for recurrent WHO grade II and III tumors range from 9 to 
30.4 weeks and from 7 to 13 months, respectively. Novel therapies for this indication are urgently needed.  
1.2 
Trabectedin 
The anticancer compound trabectedin (ET743, trade name: Yondelis) (Ref. 2) is a tetrahydroisoquinoline 
molecule originally isolated from the sea squirt Ecteinascidia turbinate (Ref. 3). The mode of action of 
trabectedin is not completely understood. However, it is known that the drug binds to the minor groove of 
the deoxyribonucleic acid (DNA) double helix forming trabectedin-DNA adducts that bend the DNA 
towards the major groove. Furthermore, trabectedin might affect diverse DNA binding proteins including 
several transcription factors and DNA repair mechanisms. The alterations induced by the drug activate the 
nucleotide excision repair (NER) pathway, which is required for maximum activity of trabectedin, while 
its activity is retained in mismatch repair-deficient cells. In vitro studies elucidated that trabectedin 
selectively inhibits the transcription of several genes, particularly those encoding the multidrug resistance 
protein 1, heat shock protein 70, and the cyclin-dependent kinase inhibitor p21WAF1/Cip1 contributing to 
the induction of programmed cell death. In addition, trabectedin has been shown to deplete tumor-
associated macrophages and act as an anti-angiogenic agent (Ref. 3, Ref. 4, Ref. 5, Ref. 6).  
Trabectedin has been shown to be active against a wide variety of cell lines and xenografts derived from 
several solid tumor types. In early clinical trials, trabectedin was active against several solid tumors 
including breast cancer, prostate cancer, renal cancer, melanoma, and non-small cell lung cancer.  
As of 1 July 2013, approximately 9,015 subjects with advanced malignancies have been treated with 
trabectedin, administered either as a single agent or in combination with other chemotherapeutic agents 
(Ref. 2). Trabectedin is generally well tolerated with manageable and mostly reversible adverse effects like 
transaminase elevations, myelosuppression, nausea, emesis, and fatigue. Creatine phosphokinase/kinase 
elevations (based on laboratory values) and rhabdomyolysis are also observed.  
Trabectedin is an emetogenic drug and prophylactic anti-emetic treatment is recommended.

Trabectedin for recurrent grade II/III meningioma 
Version 2.0

January 27, 2017 
Trabectedin has been approved and is routinely used in patients with advanced soft-tissue sarcoma (STS) 
who have failed or are not eligible for first line therapy with anthracyclines and ifosfamide and in patients 
with platinum-sensitive recurrent ovarian cancer in combination with pegylated liposomal doxorubicin.  
According to the approved dosing regimen as single agent, trabectedin is delivered as a 24-hour infusion 
every 3 weeks (day 1 of each 21-day cycle) at a starting dose of 1.5 mg/m2.  
Several ongoing clinical trials evaluate the activity of trabectedin in additional cancer types, including 
mesothelioma, pancreatic cancer, uterine leiomyosarcoma, metastatic liposarcoma or leiomyosarcoma. 
Trabectedin is also further investigated in BRCA1 and BRCA2 mutation carrier and BRCAness phenotype 
advanced ovarian cancer.  
1.3 
Study rationale 
In a recent study, strong in vitro activity of trabectedin against grade II and grade III meningioma cell lines 
with induction of distinct cell cycle arrest, down-regulation of multiple cyclins, deregulated expression of 
cell-death regulatory genes and massive apoptosis has been demonstrated (Ref. 7). In addition, high-grade 
meningiomas typically show prominent infiltration with tumor-associated macrophages and angiogenesis, 
which have been shown to be therapeutic targets of trabectedin (Ref. 6). Indeed, favorable disease 
stabilization has been documented in patient with heavily pretreated malignant meningioma (Ref. 7). 
These findings provide a rationale for further studying the potential efficacy of trabectedin in high-grade 
meningioma (Ref. 8, Ref. 9).  
Therefore, we decided to conduct a prospective clinical trial evaluating trabectedin in recurrent-high grade 
meningioma. Due to the lack of reliable historical outcome data and the lack of knowledge on the natural 
course of these tumors, a randomized trial is necessary to generate informative results. The lack of 
evidence-based treatment recommendations and the high variability in clinical practice among different 
centers prevents definition of a standard reference therapy. Therefore, “local standard of care” was chosen 
as control treatment for the current trial. The statistical design of the current trial follows the recent 
recommendations provided by the RANO group, which has summarized and reviewed outcome data for 
surgery- and radiotherapy- refractory WHO II and III meningiomas (Ref. 1). Nevertheless, as no 
randomized clinical trial data were published and patient outcome is not precisely known in this 
population, a randomized design comparing the whole PFS distribution was selected. Sample size was 
computed based on PFS-6 according to reference values provided by the RANO report i.e. a PFS-6 of 15% 
was considered a realistic outcome estimate in the control arm and a PFS-6 rate of >35% was defined as 
indicating interesting activity. Secondary end-points include the radiological benefit rate (CR and PR and 
SD), the overall survival rates at 6 and 12 months, median PFS and OS, tolerability and quality of life. 
2 Objectives of the trial 
2.1 
General objectives 
The objective of the study is to investigate whether trabectedin demonstrates sufficient antitumor activity 
against recurrent grade II or III to justify further investigation in phase III or as adjuvant therapy for newly 
diagnosed disease after resection and radiotherapy.

At the end of study, when all patients have stopped protocol treatment, complete drug reconciliation per 
batch should be available at the site for verification by EORTC in order to allow drug destruction or return 
procedure. 
Both the unused and expired study medication must be destroyed, upon authorization of the sponsor, 
according to local regulations and procedures, and a copy of the destruction form must be returned to the 
EORTC Headquarters.  
The medication provided for this trial is to be used only as indicated in this protocol and only for the 
patients entered in this study. 
5.3 
Initial dose and schedule 
Trabectedin must be administered under the supervision of a physician experienced in the use of 
chemotherapy. Its use should be confined to personnel specialized in the administration of cytotoxic 
agents. 
For this trial, the recommended starting dose is 1.5 mg/m2 BSA, administered as an IV infusion over 24 
hours with a 3-week interval between cycles. Administration through a central venous line is strongly 
recommended. 
All patients must be premedicated with corticosteroids such as dexamethasone 20 mg IV, 30 minutes 
before each trabectedin infusion; not only as anti-emetic prophylaxis, but also because it appears to 
provide hepatoprotective effects. Additional anti-emetics may be administered as needed. 
5.4 
Treatment duration 
Treatment should be administered until one of the withdrawal criteria has been met (see section 5.5). There 
is no pre-defined limit to the number of cycles to be administered. 
5.5 
Withdrawal criteria 
The treatment will always be discontinued in case of any of the events mentioned below, whichever comes 
first: 
♦ disease progression 
♦ excessive toxicity precluding further therapy, according to the responsible physician 
♦ patient refusal 
♦ pregnancy 
♦ investigator decision based on the patient’s best interest, even without documented progression 
♦ administration of concomitant drugs not allowed by the protocol (see chapter 5.7) 
♦ if entire study is terminated for medical or ethical reasons  
Patients discontinuing therapy in the absence of progression should not receive any other anti-cancer 
treatment before their disease progresses, unless this is clearly not in the interest of the patient. 

EORTC-1320-BTG 
Trabectedin for recurrent grade II/III meningioma 
Version 2.0 
21 / 69 
January 27, 2017 
After progression, the treatment will be left to the discretion of the treating physician. Any anti-cancer 
therapy other than the study drug given as single agent before disease progression within the protocol will 
not be considered as part of the protocol treatment and will be considered as protocol violation. 
5.6 
Dose and schedule modifications 
After an adverse event, patients should be under surveillance until the situation has stabilized or 
completely resolved. 
5.6.1 
Trabectedin 
At each visit during the treatment period, patients should first be evaluated for the occurrence of adverse 
events and laboratory abnormalities.  
Specific recommendations for management of these possible adverse events along with guidelines for dose 
delay/modification or discontinuation of study treatment are provided below. 
5.6.1.1 
Dose reductions 
Prior to re-treatment, patients must fulfill the eligibility criteria. If any of the following events occur at any 
time between cycles, the trabectedin dose must be reduced to 1.2 mg/m2 BSA in subsequent cycles. 
♦ Neutropenia < 0.5 x 109/L lasting for more than 5 days or associated with fever or infection. 
♦ Thrombocytopenia < 25 x109/L 
♦ Increase of bilirubin > ULN. 
♦ Alkaline phosphatase > 2.5x ULN and GGT > ULN 
♦ Increase of aminotransferases (AST or ALT) > 2.5x ULN which has not recovered to < 2.5x ULN by 
day 21 not explained otherwise 
♦ Any other Grade 3 or 4 adverse reactions (such as CPK elevation, nausea, vomiting, fatigue). 
In order to adequately assess the duration of these events, it is recommended to perform weekly 
assessments. 
Once a dose has been reduced because of toxicity, dose escalation in the subsequent cycles is not allowed. 
If any of these toxicities reappear in subsequent cycles, the trabectedin dose must be further reduced to 
1 mg/ m2 BSA. In the event that further dose reductions are necessary according to the above criteria, 
treatment should be discontinued. Colony stimulating factors can be administered for hematologic toxicity 
(neutropenia or febrile neutropenia) in subsequent cycles according to local standard practice. 
5.6.1.2 
Re-treatment criteria 
♦ A maximum delay of 3 weeks from the due date for next infusion is allowed for recovery from toxicity 
in the preceding cycle of treatment.  
♦ The following criteria should be met before the next infusion:

5.6.1.3 
Treatment discontinuation 
In the event that more than two dose reductions are required or a delay of more than 3 weeks from the due 
date for next infusion are necessary, patient must go off protocol treatment. 
5.6.1.4 
Nausea and vomiting 
Grade 3 or 4 vomiting and nausea are commonly reported during trabectedin treatment. All patients must 
be premedicated with corticosteroids such as dexamethasone. Additional anti-emetics may be administered 
as needed. 
5.6.1.5 
Injection site reactions 
The use of central venous access is strongly recommended. Patients may develop a potentially severe 
injection site reaction when trabectedin is administered through a peripheral venous line. 
There have been few reported cases of trabectedin extravasation, with subsequent tissue necrosis requiring 
debridement. There is no specific antidote for extravasation of trabectedin. Extravasation should be 
managed by local standard practice. 
5.6.1.6 
Rhabdomyolysis and severe CPK elevations  
Trabectedin must not be used in patients with CPK > 2.5x ULN. Rhabdomyolysis has been uncommonly 
reported, and severe CPK elevations were observed in 4.3% of patients treated with trabectedin 
monotherapy, usually in association with myelotoxicity, severe liver function test abnormalities or renal 
failure. Therefore, CPK should be closely monitored whenever a patient may be experiencing any of these 
toxicities or muscle weakness or muscle pain. If rhabdomyolysis occurs, supportive measures such as 
parenteral hydration, urine alkalinisation and dialysis should be promptly established, as indicated. 
Treatment with trabectedin should be discontinued until the patient fully recovers. 

EORTC-1320-BTG 
Trabectedin for recurrent grade II/III meningioma 
Version 2.0 
23 / 69 
January 27, 2017 
Caution should be taken if medicinal products associated with rhabdomyolysis (eg, statins) are 
administered concomitantly with trabectedin, since it is unknown whether the risk of rhabdomyolysis may 
be increased in these patients. 
5.7 
Concomitant treatments 
All patients must receive 20 mg of dexamethasone or an equivalent 30 minutes before administration of 
trabectedin not only as anti-emetic prophylaxis, but also because it appears to provide hepatoprotective 
effects. Additional anti-emetics may be administered as needed. 
5.7.1 
Potential Impact of other medications on trabectedin and other 
concomitant therapies 
♦ Results from the population pharmacokinetic analyses (n = 831 subjects) indicated that the plasma 
clearance of trabectedin was 19% higher in subjects who received any concomitant dexamethasone 
administration relative to those who did not. 
♦ Since trabectedin is metabolized mainly by CYP3A4, the concentrations of trabectedin in plasma are 
likely to be increased or decreased in patients who are co-administered drugs that potently inhibit (eg, 
oral ketoconazole, fluconazole, ritonavir, clarithromycin, or aprepitant) or induce (eg, rifampin, 
phenobarbital, Saint John’s Wort), respectively, the activity of this isoenzyme. The use of potent CYP 
inhibitors or inducers with trabectedin should be avoided, if possible. If concomitant use of a CYP3A4 
inhibitor is required, patients should be closely observed for toxicities, and dose delays and reductions 
should occur as per the treatment guidelines described in this protocol 
♦ Caution should be taken if medicinal products associated with hepatotoxicity are administered 
concomitantly with trabectedin, since the risk of hepatotoxicity may be increased.  
♦ Concomitant use of trabectedin with phenytoin may reduce phenytoin absorption leading to an 
exacerbation of convulsions. Combination of trabectedin with phenytoin or live attenuated vaccines is 
not recommended and with yellow fever vaccine is specifically contraindicated  
♦ Alcohol consumption must be avoided during treatment with trabectedin due to the hepatotoxicity of 
the medicinal product  
♦ Preclinical data have demonstrated that trabectedin is a substrate to P-gp. Concomitant administration 
of inhibitors of P-gp, e.g. cyclosporine and verapamil, may alter trabectedin distribution and/or 
elimination. The relevance of this interaction e.g. central nervous system toxicity has not been 
established. Caution should be taken in such situations. 
♦ Caution should be taken if medicinal products associated with rhabdomyolysis (e.g. statins), are 
administered concomitantly with trabectedin, since the risk of rhabdomyolysis may be increased. 
5.7.1.1 
Concomitant anti-cancer therapy 
♦ No concomitant anti-cancer therapy including systemic therapy, radiotherapy, or surgery while on 
protocol treatment is allowed. 
♦ No concomitant other investigational agent while on protocol treatment is allowed. 
5.7.1.2 
Permitted medications 
♦ The use of growth factors is permitted

♦ All lesions chosen as target during the initial assessment will be measured by the same method and, 
if possible, by the same person; 
♦ All investigations will be consistent with baseline in order that the development of new lesions in 
previously normal areas can also be determined.

7 Criteria of evaluation 
7.1 
Evaluation of efficacy 
Objective tumor response and time to progression will be measured according to the Macdonald response 
criteria (Ref. 11).  
Response criteria are essentially based on a set of measurable lesions identified at baseline as target 
lesions, and – together with other lesions that are denoted as non-target lesions – followed until disease 
progression. 
The following paragraphs are a quick reference to the Macdonald response criteria.  
7.1.1 
Measurability of tumor lesions at baseline 
7.1.1.1 
General method of response assessment  
Objective response to treatment is based on assessment at the treating site, following the provided imaging 
guidelines. 
Response to treatment is assessed on the basis of a set of target lesion(s) chosen before the first treatment 
administration (the complete list of target lesions must be reported on the initial measurement form before 
the start of treatment). These lesions must initially be measured in their two perpendicular dimensions, and 
these measurements must be repeated at each evaluation of the disease by the same method. Response 
evaluation for this protocol is based on neuro-radiological imaging (MRI). 
The contrast enhancing area will be considered as the basis for the tumor size assessment. Tumor size is 
defined as the product of the two largest perpendicular diameters. The initial comparison must be done 
against the baseline scan. In initially responding (≥ 50% reductions in cross-sectional areas) or stabilized 
(<50% reduction and < 25% increase in cross-sectional areas) patients, new scans must be compared to the 
nadir, i.e. the scan showing the maximum response (= minimum tumor size) during or after treatment. In 
assessing response, changes on T1-Gd+ images must be taken into consideration.

7.1.1.2 
Definition 
♦ Measurable disease - the presence of at least one measurable lesion. If the measurable disease is 
restricted to a solitary lesion, its neoplastic nature should be confirmed by cytology/histology.  
♦ Measurable lesions - tumor lesions that can be accurately measured in at least one dimension (longest 
diameter to be recorded) as ≥ 10 mm with MRI scan. Bone lesions are considered measurable only if 
assessed by CT scan and have an identifiable soft tissue component that meets these requirements (soft 
tissue component > 10 mm by CT scan). Malignant lymph nodes must be ≥ 15 mm in the short axis to 
be considered measurable; only the short axis will be measured and followed. All tumor measurements 
must be recorded in millimeters (or decimal fractions of centimeters). Tumor lesions situated in a 
previously irradiated area, or in an area subjected to other loco-regional therapy, are usually not 
considered measurable unless there has been demonstrated progression in the lesion. 
♦ Non-measurable lesions - All other lesions (or sites of disease), including small lesions are considered 
non-measurable disease. Bone lesions without a measurable soft tissue component and leptomeningeal 
disease are non-measurable. Nodes that have a short axis <10 mm at baseline are considered non-
pathological and should not be recorded or followed. 
Target Lesions. Only the following lesions are eligible as target lesions:  
♦ MRI contrast enhancing lesions with two perpendicular diameters of 10 mm or more visible on 2 or 
more axial slices which are 5 mm apart.  
♦ Target lesion(s) must be measurable in two perpendicular diameters.  
In most patients, only one lesion will be present. In case of multifocal disease, a minimum of 2 lesions and 
maximum of 5 largest enlarging lesions will be chosen as target and the sum of the products of the 
perpendicular diameters will be determined. All other lesions than target lesions, if applicable, are assessed 
according to the same schedule. They are only taken into account in two situations:  
♦ If one of them clearly progresses, the overall response to therapy will be evaluated as 
"progression", independent of the response of target lesions  
♦ All lesions must have completely disappeared to report a "complete response".  
Adequate investigations must be carried out at each evaluation of the disease to detect eventual new 
lesions. If any new lesion is found, the response will be evaluated as "progression". 
♦ By definition, non-target lesions are those that do not meet the criteria for target lesion. Measurements 
are not required but these lesions should be noted at baseline and should be followed as “present” or 
“absent”. 
All baseline evaluations should be performed as closely as possible to the beginning of treatment and never 
more than 4 weeks before the beginning of the treatment. 
7.1.2 
Tumor response evaluation 
All patients will have their overall response (OR) from the start of study treatment until the end of 
treatment classified as outlined below: 
Complete Response (CR): disappearance of all target and non-target lesions. Residual lesions (other than 
nodes < 10 mm) thought to be non-malignant should be further investigated (by cytology or PET scans) 
before CR can be accepted. Clinical evaluation must be stable or improving. No steroids should be needed. 
Partial Response (PR): at least a 50% decrease in the sum of the product of perpendicular diameters of the 
target lesions, as compared to baseline. Non target lesions must be non-PD. Clinical evaluation must be 
stable or improving. Steroid dose must be stable or diminishing. 

EORTC-1320-BTG 
Trabectedin for recurrent grade II/III meningioma 
Version 2.0 
30 / 69 
January 27, 2017 
Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD 
taking as reference the smallest tumor measurement recorded during the study. Clinical evaluation must be 
stable or improving. Steroid dose must be stable or diminishing. 
Progressive Disease (PD): at least a 25% increase in the sum of products of perpendicular diameters of the 
measured lesions taking as references the smallest tumor measurement recorded during the study 
(including the baseline scan). Appearance of new lesions (including extracranial) will also constitute PD 
(including lesions in previously unassessed areas). In exceptional circumstances, unequivocal progression 
of non-target disease may be accepted as evidence of disease progression, where the overall tumor burden 
has increased sufficiently to merit discontinuation of treatment, for example where the tumor burden 
appears to have increased by at least 73% in volume (which is the increase in volume when all dimensions 
of a single lesion increase by 20%). Modest increases in the size of one or more non-target lesions are 
NOT considered unequivocal progression. If the evidence of PD is equivocal (target or non-target), 
treatment may continue until the next assessment, but on further documentation, the earlier date must be 
used. Worsening of the clinical evaluation should also be recorded as PD.

Frequency of tumor re-evaluation 
Cranial MRI every 9 weeks from randomization until progression. 
CT thorax/abdomen only if clinically indicated; if tumorous or unclear lesions detected repeat CT every 9 
weeks and as clinically indicated. 
In the present study, tumors will be re-evaluated every 9 weeks during treatment. After discontinuation of 
protocol treatment, patients who have not progressed will still be re-evaluated every 9 weeks for the first 
year from randomization and every 12 weeks thereafter. 
7.1.2.2 
Date of progression 
This is defined as the first day when the Macdonald response criteria for PD are met.

Version 2.0 
31 / 69 
January 27, 2017 
7.1.3 
Progression Free Survival 
Progression Free Survival (PFS) will be measured from the date of randomization until the date of first 
objective progression or the date of patient's death whichever occurs first. Patients without evidence of 
progression will be censored at the last follow-up visit date. If a patient received a second anti-tumoral 
therapy without prior documentation of disease progression, the patient will be censored at the date of 
starting new anti-tumoral therapy. 
7.1.4 
Overall Survival 
Overall Survival (OS) is calculated from the date of randomization up to the date of death (any cause). For 
patients still alive or lost to follow-up at the time of analysis, survival will be censored at last follow-up 
visit date. 
7.1.5 
Overall response 
All patients included in the study must be assessed for response to treatment, even if there is a major 
protocol treatment deviation or if they are ineligible, or not followed/re-evaluated. Each patient will be 
assigned one of the following categories: complete response, partial response, stable disease, progressive 
disease, early death or not evaluable. Early death is defined as any death occurring before the first per 
protocol time point of tumor re-evaluation. 
Patients’ response will be classified as "not evaluable" if insufficient data were collected to allow 
evaluation per these criteria. 
7.1.6 
Best overall response 
Best overall response is the best response designation recorded from the date of randomization until 
disease progression. 
7.1.7 
Response duration 
Objective response duration (CR/PR) and complete response (CR) will be measured similarly to PFS (see 
above) but starting from the time measurement criteria for CR/PR or CR (whichever is first recorded) are 
first met.  
7.2 
Evaluation of safety 
7.2.1 
Adverse events 
All adverse events will be recorded; the investigator will assess whether those events are drug related 
(reasonable possibility, no reasonable possibility) and this assessment will be recorded in the database for 
all adverse events. 
Only the worst grade per CTCAE category will be recorded per cycle. The collection period will start from 
randomization up to 30 days after administration of the last dose of protocol treatment or until the start of a 
new antitumor therapy, whichever occurs first. 
All adverse events must be followed until resolution or stabilization. 
Whenever possible, the Investigator will record the main diagnosis instead of the signs and symptoms 
normally included in the diagnoses. 
Investigators must pursue and obtain information adequate both to determine the outcome and to assess 
whether it meets the criteria for classification as a SAE requiring immediate notification.

Version 2.0 
32 / 69 
January 27, 2017 
7.2.2 
General evaluation of adverse events 
This study will use the International Common Terminology Criteria for Adverse Events (CTCAE), version 
4.0, for adverse event reporting. A copy of the CTCAE can be accessed from the EORTC home page 
www.eortc.org\investigators-area\ctc. 
The highest CTCAE grading per cycle and per patient will be computed at the EORTC HQ for analysis.  
Planned safety analysis and tabulations are described in the statistics section. 
7.2.3 
Serious adverse events 
Serious adverse events are defined by the Good Clinical Practice Guideline. 
SERIOUS ADVERSE EVENTS SHOULD BE IMMEDIATELY REPORTED 
ACCORDING TO THE PROCEDURE DETAILED IN THIS PROTOCOL (see chapter 15 on 
Reporting Serious Adverse Events) 
7.2.4 
Toxic deaths 
Toxic death is defined as death due to toxicity (defined as adverse events at least with reasonable 
possibility related to study treatment). The cause of death must be reported as "toxicity". 
The evaluation of toxic deaths is independent of the evaluation of response (patients can die from toxicity 
after a complete assessment of the response to therapy). 
7.2.5 
Evaluability for safety 
All patients who have started the treatment will be included in overall safety analyses. 
For hematological events, the medical review team may decide that blood counts have not been performed 
and/or reported according to the protocol and are therefore inadequate for the evaluation of one/several 
hematological parameters in some patients. 
Patients who have discontinued treatment because of toxicity will always be included in the safety 
analyses. 
8 Statistical considerations 
8.1 
Statistical design 
8.1.1 
Sample size 
This trial is a phase II with a Korn superiority design comparing PFS between trabectedin and control with 
a treatment allocation ratio equal to 2:1 at randomization. Based on RANO recommendation (Ref. 1), PFS-
6=15% was assumed in the control arm and 35% in the trabectedin arm (i.e. 20% difference). Assuming 
PFS follows an exponential distribution, this corresponds to a treatment Hazard Ratio (HR) equal to 0.55. 
Based on the logrank test, a type I error equal to 10% one-sided (20% two sided), a power equal to 85%, 
72 progressions or deaths are needed to assess the targeted effect. 86 eligible patients who started their 
treatment (per protocol population) should be recruited (57 trabectedin, 29 control). Assuming 7.17 
patients per month (1.99 months 0-4, 3.55 months 4-8, 5.29 months 8-12 and 7.17 beyond 12 months), 
about 18 months of recruitment are needed. Events should be observed shortly (about 3-4 months) after 
end of accrual.

8.1.2 
Randomization and stratifications 
All patients entered will be centrally randomized at the EORTC Headquarters (for practical details, see 
chapter on randomization procedure). The minimization technique (Ref. 12) used by the EORTC for 
random treatment allocation is based on the variance method with semi-random assignment dependent on a 
preset threshold, as implemented by Freedman and White (Ref. 13). However, per suggestion of the ICH 
E9 statistical guidelines, the algorithm has been modified to incorporate a random allocation component in 
order to ensure an additional 15% of completely random assignments. In this trial, the threshold is set to 4, 
the total number of stratification factors. Stratification factors are: institution, pathological grade (II, III), 
age (≤, > 60) and performance status (0, >0).  
8.2 
Statistical analysis plan 
8.2.1 
Primary and secondary endpoints 
8.2.2 
Analysis populations 
♦ Intention-to-treat population: all randomized patients will be analyzed in the arm they were allocated 
by randomization 
♦ Per protocol population: all patients who are eligible and have started their allocated treatment (at least 
one dose of Trabectedin or start of local standard of care therapy) 
♦ Safety population: all patients who have started their allocated treatment (at least one dose of 
Trabectedin or start of local standard of care therapy) 
A patient will be considered to be eligible if the patient did not have any deviation from the patient 
selection criteria listed in chapter 3 of the protocol. Potential eligibility problems will be assessed by the 
Clinical Research Physician during medical review. 
8.2.3 
Statistical methods 
8.2.3.1 
Progression Free Survival 
In the per protocol population: 
PFS will be compared between trabectedin and control arm when 71 PFS events are observed. A Cox 
regression model including treatment and stratification factors at randomization (except institution) will be 
fit. If for a factor, Proportional Hazards assumptions (PH) are not respected (assessed by Schoenfeld 
residuals), the model will be stratified (i.e. not adjusted) by this factor. The superiority of trabectedin 
against the control arm will be tested at 10 % one-sided (20% two-sided) significance level. The treatment 
HR estimate will be presented with 90 % one-sided confidence interval (CI). 95% CI will also be 
presented. The PFS probability at 6 months (PFS-6) and the median PFS (mPFS) will be extracted from 
the Kaplan-Meyer PFS curve. 95% confidence intervals will be computed based on the Greenwood's 
formula. For the median the Reflected Method will provide 95% confidence intervals. 
8.2.3.2 
Radiological response 
In the per protocol population: 
The best overall response will be presented in contingency table with numbers and percentages. The 
objective response (CR/PR) and complete response rates will be reported with exact (binomial) 95% 
confidence interval. The medians of objective (PR/CR) and complete (CR) response duration will be 
extracted from their respective Kaplan-Meier curves. The Reflected Method will provide 95% confidence 
interval.

8.2.3.3 
Overall Survival 
In the per protocol population: 
OS will be compared between trabectedin and control arm. A Cox regression model including treatment 
and stratification factors at randomization (except institution) will be fit. If for a factor, Proportional 
Hazards assumptions (PH) are not respected (assessed by Schoenfeld residuals), the model will be 
stratified (i.e. not adjusted) by this factor. The superiority of trabectedin against the control arm will be 
tested at 5% two-sided significance level. The treatment HR estimate will be presented with 95% CI. The 
OS probability at 6 months (OS6), at 1 year (OS12) and the median OS (mOS) will be extracted from the 
Kaplan-Meyer OS curve. 95% confidence intervals will be computed based on the Greenwood's formula. 
For the median the Reflected Method will provide 95% confidence intervals. 
8.2.3.4 
Safety and tolerability 
In the safety population at baseline and during treatment and follow-up: 
The safety and tolerability analyses will be presented at baseline and for the whole study duration. Severe 
grades which did not resolve after treatment discontinuation or emerged during follow-up will be identified 
and listed. All forms up to the last safety assessment before progression or start of further antitumoral 
therapy will be used. Baseline will include all information recorded up to the nearest date prior to or at 
randomization. Exceptionally, assessments performed after randomization but before start of protocol 
treatment can be considered. There will be no formal comparison of safety endpoints. No p-value and 
confidence intervals will be carried out. Baseline laboratory and AE grades will not be accounted for in 
whole study duration safety analyses. Laboratory and AE events occurring in patients who did not start 
their allocated treatment will be reported separately. 
8.2.3.4.1 
Hematological parameters 
The worst value of each hematological category will be identified and graded for each patient. Frequencies 
and percentages of each category will be tabulated per arm. A table with grade 3/4 frequencies and 
percentages will be provided. 
8.2.3.4.2 
Biochemical parameters 
The worst value of each biochemical category will be identified and graded for each patient. Frequencies 
and percentages of each category will be tabulated. A table with grade 3/4 frequencies and percentages 
will be provided. 
8.2.3.4.3 
All AEs 
The worst grade of each AE item will be identified for each patient. Frequencies and percentages of each 
CTCAE term will be tabulated grouped by SOC. Tables with all grades and grade 3/4 frequencies and 
percentages will be provided. 
8.2.3.4.4 
SAEs 
After reconciliation with the SAEs listing extracted from the pharmacovigilance database, the worst grade 
of each serious AE item will be identified for each patient. Frequencies and percentages of each SOC and 
PT will be tabulated. Tables with all grades and grade 3/4 frequencies and percentages will be provided. 
8.2.3.4.5 
Related AEs 
The worst grade of each related AE item will be identified for each patient. Frequencies and percentages of 
each CTCAE term will be tabulated grouped by SOC. Tables with all grades and grade 3/4 frequencies and 
percentages will be provided.

Pre-planned sensitivity or exploratory analyses 
There is no pre-planned sensitivity analysis. Exploratory analyses may be performed on the basis of 
subgroup of patients (e.g. Ki67 expression, microvascular density, and density of tumor-associated 
macrophages), but results of these exploratory analyses may not serve as a basis for drawing conclusions 
concerning protocol treatment efficacy, and the reasons for excluding patients should be clearly reported.

Data of this trial will be included in the EORTC Brain Tumor data warehouse for further pooled data 
analyses of prognostic factors, prognostic models development and subgroup analyses. 
8.2.6 
Data re-coding and display 
Frequency tables will be tabulated (by treatment group or otherwise) for all categorical variables by the 
levels of the variables as they appear on the CRF (with %). Categories with a text field specification will 
be tabulated as categories and then supplemented by a listing with the following information for the 
patients fulfilling the condition for the specification (patient id, institution, treatment group, value of the 
item and text field contents). 
Dates relating to events prior to entry will be presented as the delay in days (or weeks, months, or years) 
between the past event and the date of entry (date of randomization – date of past event + 1) and presented 
using the median and range. For example, on the randomization checklist, the date of last administration of 
prior treatment (or the date of first diagnosis of the cancer) will be presented as the time elapsed (in days, 
weeks, months or years, as appropriate) since the day of the last administration and the date of entry on 
study (date of randomization – last administration/diagnosis +1). 
Other delays (e.g. re-treatment delays) are presented as continuous variables using the median and range. 
Continuous variables for which a coding system exists (such as for laboratory data) will be recoded into 
categories (for adverse events, the grading scale specified in the protocol will be used). Whenever no 
specific scale exists, lab data will be categorized based on the normal range: for example, below the lower 
normal limit (when appropriate), within the normal range, above the upper normal limit (ULN) and the 
degree to which it is above the ULN (for example > 2.5 x ULN, > 5 x ULN, > 10 x ULN). For laboratory 
data, the nadir is generally displayed. The nadir in a given cycle is the lowest laboratory value in that 
cycle; the overall nadir for a patient is the lowest laboratory value among all cycles.

Other continuous variables (for example age, dose …) are presented using the median and range 
(minimum, maximum) and Mean (Standard Deviation). 
If appropriate, continuous data may also be presented in categories (for example, age may also be grouped 
in decades). 
8.3 
Interim analyses 
A futility interim analysis based on boundaries from Rho family (rho=1.625) is planned when half of 
events (36) are observed. This should occur about 14.5 months after start of accrual when 61 patients are 
recruited. In absence of effect i.e. an observed PFS HR>=1, trial would be stopped for futility. With this 
boundary, there is 50% chance to stop the trial for lack of effect if the null hypothesis is true (H0). Safety 
will be reviewed by the EORTC DSMB every 6 months and by the EORTC IDMC at the time of futility 
analysis together with efficacy data. 
8.4 
End of study 
End of study occurs when all of the following criteria have been satisfied: 
1. Thirty days after last treatment administration to the last patient on protocol  
2. The trial is mature for the analysis of the primary endpoint as defined in the protocol 
3. The database has been fully cleaned and frozen for this analysis  
Follow up data might be captured for all patients after the end of study declaration in order to document 
secondary endpoints with more precision i.e. overall survival, outcome of patients according to molecular 
and pathological subgroups (see chapter 8 and 11). 
9 Data Monitoring 
Safety data are reviewed within the EORTC Headquarters on a regular basis as part of the Medical Review 
process. Problems which are identified will be discussed with the Study Coordinators who will take 
appropriate measures. Safety information will also be included in trial status reports which serve as a basis 
of discussion during EORTC Group meetings. These reports will be made available to investigators 
participating in the study. 
The EORTC Independent Data Monitoring Committee (IDMC) will review all safety problems identified 
by the EORTC Headquarters for which an advice is sought. Experts on the IDMC performing this review 
will be selected to have the relevant early trials/drug development expertise and will provide a review 
process independent of that of the Medical Review. In principle, no access to outcome data is necessary for 
safety reviews. However, the IDMC will also provide recommendations as an initial step in phase III trials 
to advise if a full review of all study data and endpoints is needed. 
The EORTC IDMC is charged with the interim review (planned in the protocol or ad hoc) of randomized 
phase II and phase III studies. When interim analyses are carried out, the interim monitoring of efficacy 
and safety data is performed according to the Statistical Considerations chapter in this protocol and 
EORTC Policy 004 on “Independent Data Monitoring Committees and Interim Analyses”. 
The results of the interim analyses are confidential and are discussed by the EORTC IDMC. The IDMC 
will subsequently recommend to the EORTC Group whether any changes should be made to the study.  
No efficacy results will be presented at EORTC Group meetings or elsewhere before the trial is closed to 
recruitment and the data are mature for the analysis of the primary endpoint, unless recommended 
otherwise by the EORTC IDMC.

10 Quality of life assessment 
Relatively little is known about the health-related quality of life (HRQoL) of meningioma patients. This is 
remarkable considering the growing interest in incorporating HRQoL as secondary outcome measure in 
primary brain tumor clinical trials (Ref. 14). Data that do exist mainly concern WHO grade I meningioma 
patients. Patients with suspected WHO grade I meningioma already have limitations in cognitive 
functioning and HRQoL (Ref. 15), while HRQoL slightly improved after surgery in a mixed group of 
WHO I-III patients (Ref. 16). Van Nieuwenhuizen et al did not demonstrate any differences in HRQoL 
between WHO I meningioma patients who had undergone surgery with or without postoperative 
irradiation on the one hand, and age-, gender-, and education-matched healthy controls on the other hand 
(Ref. 17). Another study confirmed that HRQoL long-term outcome of the majority of WHO grade I 
meningioma patients is comparable to that of the general population, except for role limitation caused by 
physical functioning. However, patients with cognitive deficits and those using anti-epileptic drugs 
(AEDs) had a compromised HRQoL (Ref. 18). Altogether, currently the scarce available data suggest that 
HRQoL might initially be compromised in meningioma patients, but is comparable to healthy controls 
when adequate treatment has been installed, apart from a subgroup of patients with severe cognitive 
deficits or on AED. Unfortunately, no specific data on HRQoL of WHO grade II and III patients are 
available. 
Evaluation of HRQoL is important to get a better understanding of the balance between the effects of 
treatment response and treatment-related side-effects from the perspective of the patients. The role of 
chemotherapy in WHO II and III meningioma is far from being established. The major endpoint in the 
current randomized phase II trial is to compare PFS between the experimental (trabectedin) and the control 
arm (local standard of care) for patients with a poor prognosis. Trabectedin has been shown to be well 
tolerated with manageable and mostly reversible adverse effects such as transaminase elevations, 
myelosuppression, nausea, vomiting and fatigue. Only few patients experience severe toxicities like skin 
and soft tissue necrosis due to extravasation or rhabdomyolysis. If treatment-related side effects influence 
the HRQoL of the patients in a negative way, however, possible advantages in terms of PFS will have to 
be balanced against the burden of treatment. It is for this reason that HRQoL is included as a secondary 
endpoint in this study. 
10.1 Objective 
The study hypothesis is that trabectedin chemotherapy will result in a PFS-6 of 35% compared to 15% in 
the control arm. In the present study, HRQoL is an important secondary endpoint. The main objective of 
HRQoL assessment within this trial is to determine the impact of trabectedin on seven chosen domains 
being primarily global QoL, with role functioning, physical functioning, cognitive functioning, 
fatigue, diarrhea, and nausea and vomiting as secondary key issues. It is expected that these were 
likely to be most affected in patients undergoing trabectedin chemotherapy. The Ho hypothesis will be 
tested to show that there is no difference between patients in both arms during and after treatment for the 
selected scales. A secondary objective is to evaluate the effect of the treatment on the remaining symptoms 
and functioning scales as treatment-related side effects may have a (temporary) negative influence on the 
health related domains of HRQoL of these patients.

10.2 HRQoL instrument 
Quality of life will be assessed with the EORTC Quality of Life Questionnaire (QLQ-C30) version 3. This 
instrument is composed of multi-item and single-item scales. These include five functional scales 
(physical, role, emotional, social, and cognitive), three symptom scales (fatigue, nausea and vomiting and 
pain), a global health status/QoL scale, and six single items (dyspnea, insomnia, appetite loss, constipation, 
diarrhea and financial difficulties). All scales and single items meet the standards for reliability. The 
reliability and validity of the questionnaire is highly consistent across different language-cultural groups. 
(Ref. 19, Ref. 20, Ref. 21) The average time to complete the questionnaire is approximately 10 minutes. 
The EORTC QLQ-C30 version 3 has been translated in over 50 languages according to a standardized 
translation procedure.  
The domains of interest as specified in the previous paragraph are covered by the Global QoL/health, role 
functioning, physical functioning, cognitive functioning, fatigue, diarrhea, and nausea and vomiting scales. 
In order to address particularities and special dimensions that pertain to the HRQoL issues in brain tumors, 
the QLQ Brain Cancer module (QLQ-BN20) will be added to the HRQoL evaluations in this trial. This 
module has been developed specifically for use in brain tumor patient populations. The QLQ-BN20 has 
shown its validity and utility. (Ref. 20, Ref. 21) The module consists of 20 items, grouped into 4 domains 
(future uncertainty, visual disorder, motor dysfunction and communication deficit) and 7 single items 
(headaches, seizures, drowsiness, hair loss, itchy skin, weakness of legs and bladder control). 
10.3 Study design 
Patients are eligible for the quality of life assessment in this study if they fulfill the eligibility criteria 
(Chapter 3) and, complete the baseline HRQoL questionnaire before randomization. Patients will be 
informed in the written patient informed consent form that they will have to undergo repeated quality of 
life assessments while involved in this trial. HRQoL will be a secondary endpoint and evaluated in a 
longitudinal design in all patients entered in this study. HRQoL is a mandatory requirement.  
10.3.1 
HRQoL schedule - timing and location 
HRQoL questionnaires must be filled out at the hospital when patients come for a scheduled visit 
according to the EORTC “Guidelines for administration of questionnaires” (see Appendix G). The pre-
treatment questionnaires must be filled within 4 weeks prior to randomization. Subsequent questionnaires 
are filled in as described in the time schedule in this paragraph.  
Electronic copies of the HRQoL questionnaires will be sent to the institutions to be printed. Additional 
translations can be provided to any institution upon request via the EORTC contact person. The case report 
forms will include a question whether the HRQoL forms have been filled in, and if not, the reason why. 
The questionnaire will be handed out to the patients by the investigator or a study nurse prior to seeing the 
doctor for clinical evaluations. The patient should complete the questionnaires by her/himself in her/his 
own language prior to seeing the treating physician at the outpatient clinic as completely and accurately as 
possible. It is recommended that a key person (e.g. research nurse) at each center should be responsible for 
questionnaire data collection in order to optimize the compliance of the patient and to ensure the 
completeness of the data. 
During the study, compliance with completing questionnaires will be investigated at each time point. The 
compliance of the HRQoL assessments will also be reviewed twice a year and will be part of the 
descriptive report.

The time windows for eligible HRQoL assessments will be as follows: 
Assessment 
Time window  
Baseline 
Can be completed before or on the day of start of protocol 
treatment but no earlier than 28 days before. 
 
Week 3 (End of cycle 1) 
To be completed during the third week after treatment start 
while on protocol treatment. 
If 3 weekly chemotherapy regimen: can be completed during 
the third week of the first cycle of chemotherapy (D15-D21 
of cycle 1). 
 
Week 6 (End of cycle 2) 
To be completed during the sixth week after treatment start 
while on protocol treatment. 
If 3 weekly chemotherapy regimen: can be completed during 
the third week of the second cycle of chemotherapy (D15-
D21 of cycle 2). 
 
Week 12 (End of cycle 4) 
To be completed during the twelfth week after treatment 
start while on protocol treatment. 
If 3 weekly chemotherapy regimen: can be completed during 
the third week of the fourth cycle of chemotherapy (D15-
D21 of cycle 4). 
 
At 6 months 
Can be completed at any time during the fifth and sixth 
month after date of randomization regardless of treatment or 
progression status. 
10.3.2 
Compliance 
Missing data may hamper assessment of HRQoL in clinical trials. This may be because centers do not 
collect the questionnaires at the appropriate time (unit non-response), and because patients may miss 
questions within the questionnaires (item non-response). The latter problem occurs less than 2% on 
average and should not be a problem. The former problem will be minimized by ensuring that participating 
centers are properly informed and motivated towards HRQoL assessment. During the study, compliance 
with completing HRQoL questionnaires will be investigated at each time point. The compliance of the 
HRQoL assessments will also be reviewed twice a year and will be a part of the descriptive report by Data 
Center for the Group's plenary sessions. The compliance rate between the 2 arms will be compared at each 
time point using a chi-square test. In order to adjust for the multiplicity of the tests, a Bonferroni 
adjustment will be made by which each test will be performed at the 0.01 significance level. Should 
serious volumes of missing questionnaires occur (below 65% at any assessment point) then the protocol 
writing committee would review the HRQoL assessment in the trial. 
Available patient numbers will diminish during the trial due to progression, death, or loss to follow-up. 
Given the low prognosis of the patient population, the HRQoL assessments appear more frequently early 
on (first 3 cycles) and only one later follow-up visit is required.

10.4 Statistical considerations 
The primary HRQoL endpoint that is considered relevant for this study is global QOL. The following 
scales will be considered as secondary HRQoL endpoints: role functioning, physical functioning, 
cognitive functioning, fatigue, diarrhea, and nausea and vomiting. The other available scales will only 
be analyzed on an exploratory basis. 
A difference of 10 points on the 100-point QLQ-C30 scale between the two arms will be considered as 
clinically relevant. The standard deviation of this scale is approximately 20 points. With the 1-sided alpha 
set at 10%, and a target difference of 10 points (effect size of 0.5), a minimum of 89 patients (in a 2:1 
randomization) yields 80% power and 76 patients would yield 75% power. Therefore, this study is 
sufficiently powered to detect differences in HRQoL. 
Data will be scored according to the algorithm described in the EORTC scoring manual. All scales and 
single items are scored on categorical scales and linearly converted to 0-100 scales. 
Changes in HRQoL scores over time will be evaluated with summary statistics. The following two 
summary statistics will be used: 
♦ During treatment: the change from baseline score to the worst score (ie minimum for functioning and 
global health scale; maximum for symptom scales) reported during treatment per patient will be 
compared. 
♦ After treatment: the change from baseline score to the score at month 6. 
Both summary statistics will be displayed via mean, median and standard deviation per treatment arm. 
Treatment differences will be displayed via mean differences and corresponding 90% confidence intervals. 
Treatment comparisons will be done via non-parametric logrank tests for the selected primary and 
secondary scales. Both statistical and clinical significance will be assessed. 
Supportive analyses will be done by calculating the proportion of patients who experience a clinical 
significant deterioration (i.e. 10 point or more worsening) for both summary statistics. 
10.4.1 
Missing data 
Missing data is a potential major source of bias in HRQoL assessment. 
In order to check the potential impact in the study, the compliance mechanism will be investigated prior to 
initiating the HRQoL analysis. Characteristics of patients with and without valid HRQoL data will be 
compared and trends over time per dropout pattern will be investigated. Model building will be used in 
order to investigate whether the compliance mechanism is linked to selected prognostic variables. 
Once the main analysis is completed, sensitivity analyses will be undertaken to verify the robustness of the 
results vis-à-vis the missing data by imputation of plausible values. In case overall compliance is deemed 
too low (<50%), only an exploratory analysis will be performed in lieu of the main analysis. 
11 Translational research 
11.1 HBM-based translational research 
Tumor FFPE blocks will be collected in real-time for retrospective central pathology review. In addition, 
the association of tumor cell proliferation, microvascular density, and density of tumor-associated 
macrophages with response to treatment will be explored using immunohistochemistry.  
Furthermore, the full landscape of potential diagnostic, prognostic, and predictive molecular markers 
within the tumor samples of the study cohort will be comprehensively profiled along an established 
pipeline dedicated to meningioma in the Dept. of Neuropathology Heidelberg (Ref. 23, Ref. 24, Ref. 25).  

EORTC-1320-BTG 
Trabectedin for recurrent grade II/III meningioma 
Version 2.0 
41 / 69 
January 27, 2017 
This analytical pipeline includes: 
♦ Next-generation-sequencing (NGS) for a custom panel of 40 genes known to be involved in 
meningioma development and progression. 
♦ Epigenetic profiling applying the Illumina 850k EPIC array for genome-wide evaluation of CpG-
island methylation status. A reference dataset of methylation patterns in meningioma of distinct 
clinical outcomes has already been generated based on 650 meningioma cases across two 
independent cohorts. This data serves as basis to allot the novel meningioma samples to 
epigenetically defined malignancy classes. Based on the array data obtained with this technology, 
also a high-resolution copy-number profile can be calculated which is of particular interest given 
the association of chromosomal alterations and progression in meningioma.  
All data will be generated and primarily stored at the Dept. of Neuropathology Heidelberg. Within the 
Dept. of Neuropathology, the data is protected from unauthorized access by the University Hospital 
Heidelberg firewall system. From there, it will be provided to the EORTC data management for correlation 
with clinical data including primary and secondary outcomes and imaging data.  
All other, not yet-defined translational research performed will be described in appropriate documents and 
all applicable regulatory and legal requirements will be met. 
11.1.1 
Biological material required for correlative molecular analysis 
To achieve the above mentioned objectives at least one paraffin block from the initial operation (diagnosis) 
or any operation performed at recurrence will be collected. If a representative FFPE block is not available, 
the collection of optimally 30, minimally 20 x 5 µm, unstained slides is required (for additional details 
please also see the HBM guidelines). FFPE tumor material has to be sent to: 
Central laboratory  
Christian Mawrin 
Otto Von Guericke Universitaet Magdeburg - Universitaetsklinik - Department of Neuropathology 
Leipziger Str. 44 
39120 Magdeburg 
Germany (Deutschland) 
In order to assess the diagnostic, prognostic, and predictive molecular markers within the tumor samples, 
the central laboratory will ship FFPE unstained slides to the Dept. of Neuropathology Heidelberg. The 
leftover material will be stored in the central laboratory in Magdeburg. 
Felix Sahm 
University of Heidelberg - Institute of Pathology 
Department of Neuropathology  
Im Neuenheimer Feld 224 
D-69120 Heidelberg 
Germany 
The informed consent for trial participation will explain the need of this material of the initial resection, 
and eventually subsequent resections for translational research. 
11.1.2 
Data storage, transfer and development of technical appendices 
The translational projects will be the result of the work of collaborating institutions and EORTC HQ. 
Bioinformatics and statistical analysis plan will be jointly developed for each project. These documents 
will be developed and approved before starting any analysis. They will specify the analytical and 
methodological details. Clinical and patient-reported outcome data will be stored in the EORTC clinical

Version 2.0 
42 / 69 
January 27, 2017 
database and biological investigational data will be stored in respective collaborating institutions. Transfer 
of data will be performed according to applicable policies in each organization (e.g. EORTC POL008) or 
according to jointly approved data transfer charters. 
11.1.3 
General principles for human biological material (HBM) collection 
Human biological material (HBM) collection involves the collection and storage of biological material, 
residual biological material or derivatives in compliance with ethical and technical requirements.  
Biobanking refers to the chain of procedures that encompass the life cycle of the biological material, e.g. 
from collection, shipping to long term storage and use, and may also be subject to local regulation and/or 
national/international legislation. 
From here, the biological material will be used or distributed to the other research laboratories involved in 
the translational research (TR) projects specified in this protocol or defined in the future.  
The following principles apply to storage of HBM: 
♦ The collected HBM should be documented, i.e. the amount remaining and its location. 
The Study coordinator and the EORTC Brain Tumor Group steering committee will be responsible for TR 
project review and prioritization, including the consideration of newly proposed TR projects not specified 
in the protocol. In case of absence or inability of the above mentioned steering committee, responsibilities 
are transferred to the Group and/or EORTC HQ as applicable. 
Final decisions on the use of HBM will be determined by a majority vote of the Brain Tumor Group 
steering committee. Additional expertise may be sought through advisory non-Group steering committee 
members. 
Access to HBM (see EORTC Biobanking Policy POL020): HBM may be used for another purpose for 
which it was originally collected, subject to meeting ethical principles/and is covered by informed 
consent/ethics approval. In the case of secondary use of HBM, (i.e. for new TR projects that are not 
specified in the clinical study protocol and that were not foreseen at the time of protocol writing) interested 
parties may apply for the use of HBM and will follow the next steps:  
♦ A short description of the new TR projects will be written and submitted to EORTC HQ for 
coordination with the appropriate Group committee. 
♦ The Group steering committee will prioritize the TR projects. Access procedures defined by the Group 
steering committee will build on the following key points:  
♦ Project prioritization  
♦ should be strongly based on scientific merit,  
♦ should consider the contribution of the different investigators to the trial and TR project,  
♦ will take into consideration if the applicant is an EORTC member or not (whilst maintaining 
the principle of access to the wider scientific community and commitments owed to study 
participants and ethical committees). 
♦ Protection of confidentiality must be respected. 
♦ An EORTC HQ feasibility check, including recommendations for regulatory and ethical matters and 
other restrictions on the use of the HBM, will take place. If in the event the HBM collections are still 
retained at individual clinical sites, the TR project leader and the involved EORTC Group are 
responsible for collecting and providing information on availability of HBM for the feasibility 
assessment. 

EORTC-1320-BTG

Version 2.0 
43 / 69 
January 27, 2017 
♦ Prioritized TR projects will then be reviewed by the Translational Research Advisory Committee 
(TRAC). 
♦ Once Group steering committee prioritization, the EORTC HQ feasibility assessment, and TRAC 
review are complete and when all applicable competent Ethics Committees approvals are in place and 
ethical principles are met, the TR project can be activated and HBM release and analysis can 
commence. 
♦ The EORTC Board will mediate any disagreements of opinion between TRAC, the EORTC HQ 
feasibility assessment, the Group steering committee and the TR project leader(s), as needed. 
11.2 Imaging-based translational research 
Retrospective review of the images will take place for this study. Although treatment decisions are based 
on objective tumor assessment at the treating sites, retrospective central review will reassess all images to 
confirm the initial assessment. 
Preliminary RANO criteria for response assessment in meningioma were presented in the RANO working 
group meeting during the 2014 ASCO annual meeting. Publication is expected. In line with the RANO 
response criteria for high-grade gliomas (Ref. 22), the RANO criteria for response assessment in 
meningioma take into account two-dimensional tumor measurements on Gd-enhanced MRI, as well as 
changes in corticosteroid dose and changes in clinical evaluation. In addition, they introduce the concept of 
minor response (MR), defined as decrease in the sum of lesion diameters between 25% and 50%. The 
criteria are summarized in table 11.1. The RANO meningioma criteria will be validated in the patients 
enrolled in the EORTC-1320 trial. 
Retrospective studies have indicated that systemic therapy may decrease the growth rate of meningiomas 
(Ref. 26). MRI scans acquired up to 2 years before inclusion of patients into the EORTC-1320 trial will be 
collected to investigate whether the growth dynamics of grade II or III meningiomas changes with start of 
study treatment.

Tables comparing best overall response to treatment between RANO and MacDonald's Criteria will be 
presented with frequencies and percentages. Discrepancies will be documented. The difference in PFS 
(definition above, same for both criteria) will be analyzed by visual comparison of the Kaplan-Meier 
curves and by tabulating PFS6, PFS9, PFS12 with 95% confidence intervals. 
12 Investigator authorization procedure 
Investigators will be authorized to randomize patients in this trial only once they have returned the 
following documents to the EORTC Headquarters:

SERIOUS ADVERSE EVENTS AND PREGNANCY NOTIFICATION FORMS SHOULD BE 
IMMEDIATELY REPORTED ACCORDING TO THE PROCEDURE DETAILED IN THIS 
PROTOCOL (see chapter 15 on Reporting Serious Adverse Events). 
A. Before the treatment starts: 
♦ The patient must be randomized in the trial by INTERNET or in case of problems by phone. 
The electronic CRFs to be completed for a patient are available on the VISTA/RDC website one hour after 
the randomization on http://rdc.eortc.be/ or on http://www.eortc.org in the investigator area. 
The paper CRFs will be made available to the institution at the time the institution is authorized. 
B. During/after treatment 
The list of forms to be completed for this study and their submission schedule are available on the 
VISTA/RDC website and are also described in the "guidelines for completion of case report forms" that 
are provided to each participating investigator.  
ALL Forms must be electronically approved and sent by the responsible investigator or one of 
his/her authorized staff members with the exception of the paper quality of life form (no signature 
needed). 
14.2 Data flow 
The forms must be completed electronically, with the exception of the paper forms (the Quality of Life 
form, SAE form and Pregnancy Notification form) according to the schedule defined in the guidelines for 
completion of Case Report Forms. 
The list of staff members authorized to enter data (with a sample of their signature) must be identified on 
the signature log and sent to the EORTC Headquarters by the responsible investigator before the start of 
the study. To enter the RDC system, the investigator or authorized staff member needs to use the same 
username and password that are used to access the interactive randomization program (ORTA). 

EORTC-1320-BTG 
Trabectedin for recurrent grade II/III meningioma 
Version 2.0 
47 / 69 
January 27, 2017 
In all cases, it remains the responsibility of the principal investigator to check that data are entered in the 
database as soon as possible and that the electronic forms are filled out completely and correctly.  
The EORTC Headquarters will perform extensive consistency checks on the received data and will issue 
queries in case of inconsistent data. The queries for the electronic forms will appear in the VISTA/RDC 
system and must be answered there directly. 
For trials with paper quality of life forms: a copy of the questionnaires should be sent to EORTC 
Headquarters as soon as possible, while the original source document should be kept on site. If there are 
queries on the quality of life form, they will be raised electronically on a patient level in the VISTA/RDC 
system and they must be answered there directly. 
The EORTC data manager will subsequently apply the corrections into the database. 
When satellite institutions are involved, all contact is made exclusively with the primary institution, for 
purposes of data collection and all other study related issues. 
If an investigator (or an authorized staff member) needs to modify a CRF after the form has been 
electronically sent to the EORTC Headquarters, he/she should create a request for data correction in the 
VISTA/RDC system. 
For trials with paper quality of life forms: if an investigator (or an authorized staff member) needs to 
modify the paper quality of life form after the copy has been sent to the EORTC Headquarters, he/she 
should create a request for data correction on a patient level in the VISTA/RDC system. 
15 Reporting of Serious Adverse Events 
ICH GCP and the EU Directive 2001/20/EC require that both investigators and sponsors follow specific 
procedures when notifying and reporting adverse events/reactions in clinical trials. These procedures are 
described in this section of the protocol.  
15.1 Definitions 
These definitions reflect the minimal regulatory obligations; specific protocol requirements might apply in 
addition. 
AE: An Adverse Event is defined as “any untoward medical occurrence in a patient or clinical 
investigation subject administered a pharmaceutical product and which does not necessarily have to have a 
causal relationship with this treatment”. An adverse event can therefore be any unfavorable and unintended 
signs (such as rash or enlarged liver), symptoms (such as nausea or chest pain), an abnormal laboratory 
finding (including results of blood tests, x-rays or scans) or a disease temporarily associated with the use of 
the protocol treatment, whether or not considered related to the investigational medicinal product. 
The following special situations should also be considered AEs, but only when they lead to an adverse 
reaction: 
♦ Drug overdose; 
♦ Drug abuse; 
♦ Drug misuse; 
♦ Drug interactions; 
♦ Drug dependency; 
♦ Off-label use; 
♦ Occupational exposure 

EORTC-1320-BTG 
Trabectedin for recurrent grade II/III meningioma 
Version 2.0 
48 / 69 
January 27, 2017 
♦ Exposure in uterus. 
Any event involving adverse drug reactions, illnesses with onset during the study or exacerbations of pre-
existing illnesses should be recorded including but not limited to clinically significant changes in physical 
examination findings and abnormal objective test findings (e.g., X-Ray, ECG). The criteria for determining 
whether an abnormal objective test finding should be reported as an AE are as follows: 
♦ The test result is associated with clinically significant symptoms, and/or 
♦ The test result leads to a change in the study dosing or discontinuation from the clinical trial, 
significant additional concomitant drug treatment or other therapy, and/or 
♦ The test result leads to any of the outcomes included in the definition of a SAE, and/or 
♦ The test result is considered to be an AE by the investigator. 
AR: An Adverse reaction of an investigational medicinal product is defined as “any noxious and 
unintended response to a medicinal product related to any dose administered”. 
All adverse events judged by either the reporting investigator or the sponsor as having a reasonable causal 
relationship to a medicinal product qualify as adverse reactions. The expression reasonable causal 
relationship means to convey in general that there is evidence or argument to suggest a causal relationship. 
UAR: An Unexpected Adverse Reaction is “any adverse reaction, the nature, or severity of which is not 
consistent with the applicable product information" (e.g. investigator's brochure for an unapproved 
investigational product or summary of product characteristics (SmPC) for a marketed product). 
When the outcome of the adverse reaction is not consistent with the applicable product information this 
adverse reaction should be considered as unexpected. 
Severity: The term “severe” is often used to describe the intensity (severity) of a specific event (as in mild, 
moderate or severe, or as described in CTC grades); the event itself, however, may be of relative minor 
medical significance (such as severe headache). This is not the same as “serious,” which is based on 
patient/event outcome or action criteria usually associated with events that pose a threat to patient’s life or 
functioning. Seriousness (not severity) serves as a guide for defining regulatory reporting obligations.  
SAE: A Serious Adverse Event is defined as any untoward medical occurrence or effect in a patient, 
whether or not considered related to the protocol treatment, that at any dose: 
♦ results in death 
♦ is life-threatening (i.e. an event in which the subject was at risk of death at the time of event; it does not 
refer to an event which hypothetically might have caused death if it was more severe) 
♦ requires inpatient hospitalization or prolongation of existing patient hospitalization (unless exempted 
from SAE reporting (see section 15.2)). 
♦ results in persistent or significant disability or incapacity 
♦ is a congenital anomaly or birth defect 
♦ is a medically important event or reaction. 
Medical and scientific judgment should be exercised in deciding whether other situations should be 
considered serious such as important medical events that might not be immediately life-threatening or 
result in death or hospitalization but might jeopardize the patient or might require intervention to prevent 
one of the other outcomes listed in the definition above. Examples of such events are intensive treatment in 
an emergency room or at home for allergic bronchospasm, blood dyscrasias or convulsions that do not 
result in hospitalization, or development of drug dependency or drug abuse. 

EORTC-1320-BTG 
Trabectedin for recurrent grade II/III meningioma 
Version 2.0 
49 / 69 
January 27, 2017 
A suspected transmission via medicinal product of an infectious agent is also considered a serious adverse 
reaction. 
Death, as such, is the outcome of a SAE and should not be reported as the SAE term itself. Instead the 
cause of death should be recorded as the SAE term. When available, the autopsy report or its main 
conclusions in English will be provided to the Sponsor. 
SAR: A Serious Adverse Reaction is defined as any SAE which is considered related to the protocol 
treatment.  
SUSAR: Suspected Unexpected Serious Adverse Reaction.  
SUSARs occurring in clinical investigations qualify for expedited reporting to the appropriate Regulatory 
Authorities within the following timeframes: 
♦ Fatal or life-threatening SUSARs within 7 calendar days 
♦ Non-fatal or non-life-threatening SUSARs within 15 calendar days 
Inpatient hospitalization: a hospital stay equal to, or greater than, 24 hours. 
Prolongation of hospitalization is defined as any extension of an inpatient hospitalization beyond the stay 
anticipated/required for the initial admission, as determined by the Investigator or the treating physician. 
Second primary malignancy is one unrelated to the treatment of a previous malignancy (and is NOT a 
metastasis from the previous malignancy). 
Secondary malignancy is a cancer caused by treatment for a previous malignancy (e.g., treatment with 
investigational agent/intervention, radiation or chemotherapy). A secondary malignancy is not considered 
a metastasis of the previous malignancy. 
15.2 Exceptions 
The following situations shall not be reported as SAEs:  
♦ Elective hospitalization for pre-existing conditions that have not been exacerbated by trial treatment. 
♦ A hospitalization which was planned before the patient consented for study participation and where 
admission did not take longer than anticipated. 
♦ A hospitalization planned for protocol related treatment or protocol related procedure as per 
institutional standard timelines. However, events requiring hospitalizations or prolongation of 
hospitalization as a result of a complication of therapy administration or clinical trial procedures will 
be reported as SAEs. 
♦ Social, technical, administrative and/or convenience admission to a hospital, in absence of a SAE 
♦ Medical or surgical procedure (e.g. endoscopy, appendectomy); the condition that leads to the 
procedure should be reported if meets the definition of an (S)AE. For example, an acute appendicitis 
that begins during the adverse event reporting period should be reported as the (S)AE, and the resulting 
appendectomy should be recorded as treatment of the AE. Situations where an untoward medical 
occurrence did not occur (palliative care, rehabilitation, overdose without occurrence of an adverse 
event). 
♦ Anticipated day-to-day fluctuations of pre-existing disease(s) or condition(s) present or detected at the 
start of the study that do not worsen. 
♦ An emergency visit due to an accident where the patient is treated and discharged. 
♦ When the patient is held 24 hours for observation and finally is not admitted. 

EORTC-1320-BTG 
Trabectedin for recurrent grade II/III meningioma 
Version 2.0 
50 / 69 
January 27, 2017 
♦ Planned treatments at sites not associated to a hospital and generally considered as minor surgical 
procedures (i.e., laser eye surgery, arthroscopy, etc). 
By EORTC convention, clinical events related to the primary cancer being studied or to the primary cancer 
progression are not to be reported as SAEs, even if they meet any of the seriousness criteria from the 
standard SAE definition (i.e. fatal, hospitalization, etc.),.),.), unless the event is more severe than expected 
and therefore the investigator considers that their clinical significance deserves reporting.  
15.3 Severity assessment 
The severity of all AEs (serious and non-serious) in this trial should be graded using CTCAE v4.0 
www.eortc.org\investigators-area\ctc 
15.4 Causality assessment 
The investigator is obligated to assess the relationship between protocol treatment and the occurrence of 
each SAE following the definitions in this table: 
Relationship to the 
protocol treatment  
Description 
Reasonable possibility 
There is a reasonable possibility that the protocol treatment caused 
the event 
No reasonable 
possibility 
There is no reasonable possibility that the protocol treatment caused 
the event 
 
The investigator will use clinical judgment to determine the relationship. Alternative causes, such as 
natural history of the underlying diseases, medical history, concurrent conditions, concomitant therapy, 
other risk factors, and the temporal relationship of the event to the protocol treatment will be considered 
and investigated. 
The decision will be recorded on the SAE form and if necessary the reason for the decision will also be 
recorded. 
15.5 Expectedness assessment 
The expectedness assessment is the responsibility of the sponsor of the study. The expectedness 
assessment will be performed against the following reference documents: 
♦ Trabectedin: most updated Investigator's Brochure. 
♦ Local standard of care treatment: Summary of Product Characteristics (SmPC). 
If information on expectedness has been made available by the reporting investigator, this should be taken 
into consideration by the sponsor. 
15.6 Reporting procedure for investigators 
This procedure applies to all Serious Adverse Events (SAEs) occurring from the time a subject is 
randomized until 30 days after last protocol treatment administration, or until the start of a new antitumor 
therapy, whichever occurs first; and to any SAE that occurs outside of the SAE detection period (after the 
30-days period), if it is considered to have a reasonable possibility to be related to the protocol treatment or 
study participation.

Randomization till 30 days after last protocol treatment 
administration, or until the start of a new antitumor therapy, 
whichever occurs first:  
All SAEs 
From day 31 after last protocol treatment administration (or 
after start the start of a new antitumor therapy): 
Only related SAEs 
 
Any secondary malignancy should also be reported in expedited way on a SAE form with the 
appropriate seriousness criteria! 
All reporting must be done by the principal investigator or authorized staff member (i.e. on the signature 
list) to confirm the accuracy of the report. 
All SAE data must be collected on the study-specific SAE form. 
All SAEs must be reported immediately and no later than 24 hours from the time the investigator or staff 
became aware of the event. 
All SAE-related information needs to be provided in English. 
All additional documents in local language must be accompanied by a translation in English, or the 
relevant information must be summarized in a follow-up SAE report form. 
All SAE-related information must be send to the EORTC Pharmacovigilance Unit: 
 
EORTC Pharmacovigilance Unit: 
 
Fax No. +32 2 772 8027 
 
pharmacovigilance@eortc.be  
To enable the Sponsor to comply with regulatory reporting requirements, all initial SAE reports should 
always include the following minimal information: an identifiable patient (SeqID), a suspect medicinal 
product if applicable, an identifiable reporting source, the description of the medical event and seriousness 
criteria, as well as the causality assessment by the investigator. Complete information requested on the 
SAE form of any reported serious adverse event must be returned within 7 calendar days of the initial 
report. If the completed form is not received within this deadline, the Pharmacovigilance Unit will make a 
written request to the investigator. 
Queries sent out by the EORTC Pharmacovigilance Unit need to be answered within 7 calendar days. 
The investigator must provide any relevant information as requested by the Sponsor in addition to that on 
the CRF. 
All forms need to be dated and signed by the principal investigator or any authorized staff member (i.e. on 
the signature list). 
15.7 Reporting responsibilities for EORTC 
The EORTC Pharmacovigilance Unit will forward all SAE reports to the appropriate persons within the 
EORTC Headquarters and to the pharmacovigilance contact at the pharmaceutical company. 
The EORTC Pharmacovigilance Unit will provide a six-monthly summary which will be added in the Trial 
Status Report and which will be accessible to all participating investigators.  
The EORTC Pharmacovigilance Unit will take in charge the reporting of SUSARs/unexpected events to 
the Competent Authorities, Ethics committees, EudraVigilance Clinical Trial Module (EVCTM) and all 
participating investigators whenever applicable, following the local and international regulatory 
requirements.

January 27, 2017 
15.8 Pregnancy reporting 
Pregnancy occurring during a patient’s participation in this trial, although not considered an SAE, must be 
notified to the EORTC Pharmacovigilance Unit within the same timelines as an SAE (within 24 hours) on 
a Pregnancy Notification Form. The outcome of a pregnancy should be followed up carefully and any 
adverse outcome to the mother or the child should be reported. This also applies to pregnancies in female 
partners of a male patient participating in this trial. 
♦ Any pregnancy in a female patient diagnosed during the treatment period or within 3 months thereafter 
or in a female partner of a male patient diagnosed during the treatment period or within 5 months 
thereafter, must be reported to the EORTC Pharmacovigilance Unit 
♦ This must be reported within 24 hours of first becoming aware of the event by fax, to the 
Pharmacovigilance Unit on a Pregnancy Notification Form  
♦ If a SAE occurs in conjunction with the pregnancy, please also complete an SAE form as explained in 
the SAE reporting chapter 
♦ All neonatal deaths that occur within 30 days of birth should be reported, regardless to the causality, as 
SAEs. In addition, any infant death at any time thereafter that the Investigator suspects to be related to 
the exposure to the study drug/IMP should also be reported to the Pharmacovigilance Unit by facsimile 
within 24 hours of the Investigator´s knowledge of the event. 
16 Quality assurance 
16.1 Control of data consistency 
Data forms will be entered in the EORTC Headquarters database by using the VISTA/RDC (Remote Data 
Capture) system. Computerized and manual consistency checks will be performed on newly entered forms; 
queries will be issued in case of inconsistencies. Consistent forms will be validated by the Data Manager. 
Inconsistent forms will be kept "pending" until resolution of the inconsistencies. 
16.2 On-site quality control 
The EORTC Headquarters will perform on-site quality control visits. 
The first visit in a participating site will be performed within 6 months after the first patient's 
randomization at this site. Frequency and number of subsequent visits will depend on site's accrual and 
quality observed during the first visit.  
Overall, the frequency of site visits will be around one visit a year per recruiting site. 
The aim of these site visits will be: 
♦ to verify that the site facilities remain adequate for performing the trial 
♦ to verify that the principal investigator and site staff involved in the trial are working in compliance 
with GCP and protocol requirements  
♦ to assess the consistency of data reported on the case report forms with the source data 
♦ to check that Serious Adverse Events have been properly reported and that follow-up information or 
queries are correctly fulfilled 
♦ to assist the site in resolving any outstanding queries 
♦ to control the drug accountability process

January 27, 2017 
16.3 Audits 
The EORTC Quality Assurance and Control Unit (QA&C) regularly conducts audits of institutions 
participating in EORTC protocols. These audits are performed to provide assurance that the rights, safety 
and wellbeing of subjects are properly protected, to assess compliance with the protocol, processes and 
agreements, ICH GCP standards and applicable regulatory requirements, and to assess the quality of data. 
The investigator, by accepting to participate in this protocol, agrees that EORTC, any third party (e.g. a 
CRO) acting on behalf of the EORTC, or any domestic or foreign regulatory agency, may come at any 
time to audit or inspect their site and all subsites, if applicable.  
This audit consists of interviews with the principal investigator and study team, review of documentation 
and practices, review of facilities, equipment and source data verification. 
The investigator will grant direct access to paper and/or electronic documentation pertaining to the clinical 
study (e.g. CRFs, source documents such as hospital patient charts and investigator study files) to these 
authorized individuals. All site facilities related to the study conduct could be visited during an audit (e.g. 
pharmacy, laboratory, archives …). The investigator agrees to co-operate and provide assistance at 
reasonable times and places with respect to any auditing activity. 
If applicable, the company(ies) supplying the study drug(s) may have access to anonymized data but will 
not have access to source documents. 
If a regulatory authority inspection is announced, the investigator must inform the EORTC Headquarters 
QA&C Unit immediately (contact at: QualityAssuranceandControlUnit@eortc.be). 
In this way EORTC can provide support in preparing and/or facilitating the inspection. EORTC 
representatives/delegates may also attend the inspection. 
16.4 External review of histology 
Retrospective central histopathology review is planned to be undertaken as a downstream translational 
research project, as described in the appropriate section. 
16.5 External review of responses 
In accordance with the recommendations of the Macdonald criteria, all responses will be reviewed by an 
expert or experts independent of the study. 
16.6 Scan submission Quality Assurance and Quality Control in 
imaging 
All imaging data for this trial will be centrally collected and stored, using the EORTC Imaging Platform. 
Sites are requested to submit the imaging data in a timely fashion manner to allow prospective QA/QC to 
be performed. MRI scans acquired during the trial and up to 2 years before inclusion of patients into this 
trial will be collected to investigate whether the growth dynamics of grade II or III meningiomas changes 
with start of study treatment. 
In case sites are not able to transfer the imaging data electronically, the data will be sent to EORTC HQ in 
a CD/DVD via courier and the EORTC Imaging Team will be in charge of uploading the data on the 
EORTC imaging platform. Further details about the imaging data transfer can be found in the Imaging 
Guidelines. 
The EORTC HQ will track all scans of all patients received from the sites and will request/query 
missing/incomplete scans. Furthermore, if the scans arrive in unacceptable quality or in a non-acceptable 
format, the site will be informed to provide substitute scans.

16.6.1 
Imaging QA/QC level description 
All documents pertaining to the Imaging QA/QC procedures will be sent to centers after receipt of the 
signed commitment form at the EORTC Headquarters.  
The QA procedure consists of completing the following, which must be performed: 
♦ Prior to site authorization: 
♦ Imaging Guidelines “read and understood” acknowledgment signature page.  
♦ Dummy run (DR) 
♦ During the trial, the following imaging procedures will be performed: 
♦  Prospective scans QA/QC 
♦  Retrospective Central Review 
16.6.1.1 
Imaging guidelines “read and understood” acknowledgment signature page  
This is the first page of the imaging guidelines. Every site participating in an EORTC study with imaging, 
must comply with the minimum requirements established as specified in the imaging guidelines. The first 
page of the imaging guidelines must be signed and returned to the EORTC HQ for every new version of 
the imaging guidelines. The page must be signed by the department head nuclear medicine physician and 
radiologist. This is mandatory from all institutions in this study before activation to participate in it.  
16.6.1.2 
Dummy run  
Prior to enrolling patients to participate in this trial, centers are required to submit a test scan of the 
imaging modalities required per protocol, called dummy run (DR) scan to be reviewed by the EORTC 
Imaging team or its back-up, who will verify image quality, consistency of acquisition/reconstruction 
parameters and imaging guidelines compliance with the protocol requirements. The DR scan will not be 
analyzed further. For more details on DR acquisition, reconstruction and submission please refer to the 
Imaging Guidelines.  
16.6.1.3 
Prospective scan quality control  
QA/QC will be performed prospectively, on an on-going basis for all imaging data collected for the trial.  
The EORTC Imaging team or its back-up will be reviewing all scans for all patients to check for artifacts 
and to ensure compliance with the imaging guidelines and study protocol requirements. All acquisition and 
reconstruction parameters will be checked and recorded through the study.  
Every subsequent scan on the same patient must be done with the same scanner across all visits. In case of 
scanner breakdown or change of scanners in the department, you need to notify the EORTC HQ.  
16.6.1.4 
Central review 
A Blinded Independent Central Review (BICR) will be organized retrospectively to review all collected 
scans in this study.  
The BICR will remain blinded regarding the treatment group of the patients. Furthermore, the reviewers 
will be blinded regarding the site’s assessment which will only be unblinded to the study coordinator. 
BICR ensures an independent evaluation of patient scans in a specific study by experts in the specific 
imaging modality. For further details about the Independent Central Review, please refer to the Central 
Review Charter.

17 Ethical considerations 
17.1 Patient protection 
The responsible investigator will ensure that this study is conducted in agreement with either the 
Declaration of Helsinki (available on the World Medical Association web site (http://www.wma.net)) 
and/or the laws and regulations of the country, whichever provides the greatest protection of the patient. 
The protocol has been written, and the study will be conducted according to the ICH Harmonized 
Tripartite Guideline on Good Clinical Practice (ICH-GCP, available online at 
http://www.ema.europa.eu/docs/en_GB/document_library/Scientific_guideline/2009/09/WC500002874.pd
f). 
The protocol must be approved by the competent ethics committee(s) as required by the applicable 
national legislation. 
17.2 Subject identification 
The name of the patient will neither be asked for nor recorded at the EORTC Headquarters. A sequential 
identification number will be automatically allocated to each patient registered in the trial. This number 
will identify the patient and will be included on all case report forms. In order to avoid identification 
errors, the patient’s code (maximum of 4 alphanumerics) and date of birth or year of birth (as allowed per 
applicable legislation) will also be reported on the case report forms. 
17.3 Informed consent 
All patients will be informed about 
♦ the aims of the study 
♦ the possible adverse events 
♦ the procedures and possible hazards to which the patient will be exposed 
♦ the mechanism of treatment allocation 
♦ strict confidentiality of any patient data 
♦ medical records possibly being reviewed for trial purposes by authorized individuals other than their 
treating physician 
The template of the patient’s informed consent statement is given as a separate document dated and 
version controlled to this protocol. 
An adapted translation of the PIS/PIC will be provided by EORTC Headquarters and it is the responsibility 
of the Coordinating investigators for this trial (sometimes called National Coordinators) to adapt it to 
national/local requirements where necessary. 
The translated informed consent documents are to be submitted to ethics committees for approval. The 
competent ethics committee for each institution must approve the informed consent documents before the 
center can join the study. It is the responsibility of the competent ethics committee to ensure that the 
translated informed documents comply with ICH-GCP guidelines and all applicable national legislation. 
It is emphasized in the patient information sheet that participation is voluntary and that the patient is free to 
refuse further participation in the protocol whenever he/she wants to. This will not have any impact on the 
patient’s subsequent care. Documented informed consent must be obtained for all patients included in the 
study before they are registered and/or randomized at the EORTC Headquarters. The written informed 

EORTC-1320-BTG

Version 2.0 
56 / 69 
January 27, 2017 
consent form must be signed and personally dated by the patient or by the patient’s legally acceptable 
representative. 
All of the above must be done in accordance with the applicable national legislation and local regulatory 
requirements. 
18 Administrative responsibilities 
18.1 The study coordinator 
The Study Coordinator works closely with the study team to develop the outline and full protocol and

EORTC Quality of Life evaluation: guidelines for administration of questionnaires 
The instructions given below are intended to provide some general guidelines for collecting quality of life 
(QOL) data in EORTC studies. These instructions apply for all types of questionnaires. 
1. Who is the responsible person (RP) for QOL data collection? 
In each institution, the principal investigator is the responsible for the local organization of QoL data 
collection. This can be delegated to a physician, data manager, (research) nurse or a psychologist. Such a 
person should have the full protocol at his/her disposal as well as the questionnaire(s). This person would 
also be the intermediate contact point in case of any necessary clarification asked by the EORTC 
Headquarters. 
2. Who should fill out the questionnaire? 
In principle it is the patient who has to complete the QOL forms and preferably without help from others. 
In the case where a patient is too sick to fill out the questionnaire by him/herself or if the patient is not able 
to complete the questionnaire for such reasons as forgetting his/her glasses, another person could read the 
questions without making any suggestions and report the answers on the forms. It is not allowed for 
another person to fill in the questionnaire as if (s)he was the patient (proxy assessment) unless specifically 
allowed by the protocol. 
3. What instructions should be given to the patient? 
At entry in a study, the RP should give the patient an explanation of the objective of the study and 
instructions for completing the questionnaires. 
The patient should be informed that participation in the QOL protocol is voluntary and that the information 
provided is confidential (identification is only for administrative purposes and includes date of birth and 
today’s date (completion date)). 
The following issues should be explained to the patient: 
♦ The schedule of assessments. 
♦ The questionnaire is a self administered questionnaire that should be completed by the patient 
him(her)self. The patient can ask for aid in reading or writing but should not let another person provide 
the answers. 
♦ The patient should   circle   the choice that best corresponds to his/her situation. 
♦ There is no right or wrong answer to any of these questions. The answers will not influence any 
 
medical decision making. 
♦ All questions should be answered.  
♦ The patient will be given a questionnaire in the default language(s) of the hospital. If desired, the 
 
patient may request another language. The RP will then contact the EORTC Headquarters for the 
 
appropriate translation. 
The RP should make sure that the patient understands the instructions.

67 / 69 
January 27, 2017 
At each subsequent assessment as defined by the protocol, the patient should receive the questionnaire 
from the RP or from other appropriate staff if the RP is unavailable. 
4. Where should the patient complete the questionnaire? 
The patient should complete the questionnaire at the clinic, and, ideally in a quiet, private room. If this is 
not possible, the waiting room is an acceptable alternative. In general it does not take long to complete the 
questionnaire, but patients should be given the time they need to answer all questions. 
5. When should they complete the questionnaire? 
The timing of the planned QoL assessments is detailed in the protocol. When a QOL assessment is 
planned, the questionnaire should be given to the patient preferably before the meeting with the physician, 
ensuring that the patient has enough time to complete the questionnaire. If the patient is to receive a 
therapy, the questionnaire should be filled out before administration of the treatment (unless indicated 
otherwise in the protocol). The questionnaire should not be taken home and/or mailed (unless indicated 
otherwise in the protocol). 
6. Review of the completed questionnaire 
After the patient has completed the questionnaire, the person handling the questionnaire should: 
♦ Complete the “Hospital Staff” specific data box. 
♦ Check that the completion date is correctly filled in by the patient. 
♦ Screen the questionnaire for omissions. 
If this is the case: 
♦ Please ask the patient the reason for omissions. It may be that patient forgot to flip a page or did not 
understand a question. The patient should not be forced to provide an answer if (s)he does not wish to 
do so. 
♦ Additional explanation may be provided, but the questions should not be rephrased. 
7. Missing forms 
If for some reason the patient is unable or does not wish to complete a quality of life questionnaire the 
reason and the date of visit should be documented on the corresponding CRF (case report form).  
8. Mailing to EORTC Headquarters 
A copy of the questionnaires should be sent to EORTC Headquarters as soon as possible, while the 
original source document should be kept on site. As it is impossible to retrospectively collect missing 
quality of life data, please make sure the patient completes the questionnaire at the time-point when he/she 
is supposed to complete it. 
Thank you very much for your cooperation. If you have any remarks about this leaflet or if you need 
further information, please contact:
