E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the efficacy of 2-OHOA in combination with the standard of care (SoC) treatment of radiotherapy (RT) and TMZ, as assessed by: • Progression Free Survival (PFS) using the Response Assessment in Neuro-Oncology (RANO) criteria for conditional marketing authorization (CMA) application • Overall Survival (OS), for full marketing authorization (FMA) application. The selection of the most appropriate dose, the detection of a large range of treatment effect (through sample size re-estimation) and the characterisation of an optional sub-group of responders (signature detection feature), are primary objectives integrated in the adaptive design of the study.
|
|
E.2.2 | Secondary objectives of the trial |
• To evaluate clinical response: o Changes in neurological function, based on Neurologic Assessment in Neuro-Oncology (NANO) criteria • To evaluate additional measures of efficacy including: o Time to Progression (TTP) (as assessed using RANO criteria) • To evaluate Health-related Quality of Life (HRQoL) • To characterize the safety and tolerability of 2-OHOA in combination with RT and TMZ. • To characterize the pharmacokinetics (PK) and pharmacodynamics (PD) of 2-OHOA in combination with RT and TMZ. • To explore further the mechanism of action (MoA) of 2-OHOA.

Adequate hepatic function defined by a total bilirubin level ≤ 1.5 × the upper limit of normal range (ULN), an aspartate aminotransferase (AST), level ≤ 2.5 × ULN, and an alanine aminotransferase (ALT) level ≤ 2.5 × ULN or, for subjects with documented metastatic disease to the liver, AST and ALT levels ≤ 5 × ULN. Subjects with documented Gilbert disease are allowed if total bilirubin ≤ 3 x ULN 13. Adequate renal function defined by an estimated creatinine clearance ≥ 30 mL/min according to the Cockcroft-Gault formula

E.5 End points |
E.5.1 | Primary end point(s) |
• PFS according to RANO criteria evaluated after 150 PFS events occur. Occurrence of disease progression to calculate PFS will be determined first by the investigator based on local evaluation of images and other clinical information. Progression will be confirmed by an adjudication/imaging committee. • Overall Survival evaluated after 133 OS events are observed.
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Assessed respectively after observing at least 150 Progression-Free Survival events and 133 Overall Survival events, respectively. It is expected that the analysis for Progression-Free Survival can be performed about 2 years earlier than the analysis for Overall Survival. |
|
E.5.2 | Secondary end point(s) |
• Changes in neurological function, based on Neurologic Assessment in Neuro-Oncology (NANO) criteria • To evaluate additional measures of efficacy including: o Time to Progression (TTP) (as assessed using RANO criteria) • HRQoL assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, EORTC-QLQ C30, version 3.0 and brain cancer specific QLQ-BN20. • The incidence of adverse events (AEs) related to the 2-OHOA combination with RT and TMZ and according to NCI CTCAE, version 5.0. • Population pharmacokinetics will be evaluated in plasma samples collected according to a sparse sampling scheme. • Proteomic, genomic, lipidomic and transcriptomic biomarkers in blood and tumour tissue
|
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Each secondary endpoint will be tested in the order listed only after the superiority of dose selected (Arm B or C) compared to placebo (Arm A) with respect to the primary efficacy endpoints (PFS and OS) is established and all preceding secondary efficacy endpoints show statistically significant results |
