E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of Phase I is to determine toxicity of meclofenamate sodium therapy in addition to standard temozolomide and, on this base, determine the daily meclofenamate sodium dose to be recommended for phase II. In Phase II, the primary objective is efficacy of meclofenamate sodium therapy in addition to standard therapy. |
|
E.2.2 | Secondary objectives of the trial |
To determine the efficacy of meclofenamate sodium therapy in addition to standard temozolomide throughout the trial. To assess the safety and tolerability of meclofenamate sodium therapy in addition to standard temozolomide throughout the trial. To evaluate the clinical effect of meclofenamate sodium therapy in addition to temozolomide and the development of quality of life throughout the trial. |

E.2.3 | Trial contains a sub-study | No |

Cognitive state to understand rationale and necessity of study therapy and procedures 5. MGMT promotor-methylated (MGMTmeth), IDH wildtype glioblastoma (GBM) or gliosarcoma con-firmed with histology of the primary resection 6. age > 18 years 7. Karnofsky performance score (KPS) ≥60%; 8. Life expectancy > 6 months 9. Adequate bone marrow reserve (WBC >3 G/nl, platelets >100 G/nl) 10. Adequate liver function (bilirubin <1.5 x ULN; ASAT /ALAT <3 x ULN, creatinine < 1.5 x ULN) 11. Patient compliance and geographic proximity that allow adequate follow up 12. Male and female patients with reproductive potential must use an approved contraceptive method during and for 3 months after the trial (Pearl index <1%) 13. Pre-menopausal female patients with childbearing potential: a negative serum pregnancy test (beta-HCG) must be obtained prior to treatment start Additional inclusion criterion ONLY for phase I: 14. Resection at first relapse not yet performed; according to the local treating neurosurgeon and the documented decision of local neurooncological tumor board, reresection of the tumor is clinically indicated and can be safely de-ferred until day 7-10 after initiation of MFA/TMZ therapy.

E.4 | Principal exclusion criteria |
1. Indication for hematotoxicity in first-line therapy not allowing TMZ starting dose 150 mg/m2/d 2. Skin or liver toxicity >CTCAE5 grade 1 in first-line therapy 3. History of gastrointestinal bleeding or gastroduodenal ulcer, active gastritis 4. History of asthma, urticaria or allergic-type skin reactions to NSAID 5. Prior malignancy other than glioma 6. History of confirmed or suspected hypersensitivity (delayed type and immediate type, inclusive of anaphylactic reaction) to any background/ standard TMZ drug product or one of its ingredients of the chosen product, or to cyclooxygenase inhibitors (“NSAIDs”), or to any ingredient of meclofenamate drug product 7. History of disease with poor prognosis 8. Severe coronary heart disease (esp. after coronary artery bypass graft or history of myocardial infarction), severe heart failure 9. Known HIV infection, active hepatitis B or C 10. Breastfeeding or pregnant 11. Unable to undergo contrast-enhanced MRI (i.e. contrast allergy, implants, etc). 12. Treatment in another clinical trial with therapeutic medical intervention or use of any other investiga-tional agent during the trial or within the 30 days before enrollment 13. Medication with a drug that is not allowed in conjunction with MFA intake and cannot be discontin-ued: i.e. lithium, methotrexate, etc. 14. Patients with active bleeding, bleeding diathesis, antiplatelet therapy or anticoagulant therapy except for the following anticoagulants which are permitted for low-dose thrombosis prophylaxis up to the dosage specified here: unfractionated heparin 7,500 IU BID or 5,000 IU TID; low molecular weight heparin e. g. enoxa-parin 40 mg/d; fondaparinux 2.5 mg/d; danaparoid sodium 750 IU BID; argatroban IV route throm-bin time < 70 s; vitamin-K-antagonist INR < 1.8; dabigatran 150 mg BID; rivaroxaban 10 mg/d; edoxaban 30 mg/d; epixaban 2.5 mg BID This restriction is due to a potentially increased risk of GI ulcers with subsequent bleeding under MFA therapy 15. Patients with medically diagnosed hereditary Galactose Intolerance, complete lactase deficiency or confirmed Glucose-Galactose-Malabsortion 16. Medical History of gastrointestinal Resection of any kind that may potentially alter the absorption of the investigational study drug, according to investigators judgement 17. The presence of any other concomitant severe, progressive, or uncontrolled renal, hepatic, hematological, endocrine, pulmonary, cardiac (including coronary artery bypass graft), or psychiatric disease, or signs and symptoms thereof, that may affect the subjects participation in the study, according to investigators judgement |

|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
After 56 days of meclofenamate sodium treatment (DLT incidence) and at diagnosis of progressive disease determined by MRI (RANO criteria) in the local center (PFS). |
|
E.5.2 | Secondary end point(s) |
Phase I: Progression-free survival (PFS); Overall survival (OS); Assessment of safety beyond 8 weeks MFA treatment: Toxicity, i.e. continuous monitoring of AE/SAE/SUSARs; Karnofsky performance score (KPS), Quality of life (QoL) and Mini-Mental-status examination (MMSE). Phase II: PFS according to post hoc central reference neuroradiological assessment; OS; Assessment of safety: Toxicity, i.e. continuous monitoring of AE/SAE/SUSARs; KPS, QoL and MMSE. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Phase I: PFS is measured at diagnosis of progressive disease determined by MRI (RANO criteria) in the local center and according to post hoc central reference neuroradiological assessment; OS is measured from the day of inclusion into the trial; Safety is measured until 3 days after end of therapy; KPS, QoL and MMSE are measured throughout the trial. Phase II: PFS is measured post hoc at the central reference neuroradiological assessment; OS is measured from the day of randomization in phase II; Safety is measured until 3 days after end of therapy; KPS, QoL and MMSE are measured throughout the trial. |
