Purpose

This is an open-label, single arm, Phase 1 study to assess the safety and tolerability of macitentan in combination with dose-dense temozolomide in adult patients with recurrent glioblastoma or gliosarcoma. The study is composed of three parts. A Phase 1 Dose Escalation Period with a traditional 3+3 design will determine the maximum tolerated dose of macitentan in combination with dose-dense temozolomide. A Phase 1b Period will expand the safety and tolerability data of two doses of macitentan and dose-dense temozolomide selected from the Dose Escalation Period and explore efficacy. An Ancillary Study will further evaluate the effects of macitentan on biomarkers in brain tumor tissue.

The study is planned to have a minimum duration of 12 months. The study will end when all patients (excluding those prematurely withdrawn or lost to follow-up) in each part of the study have completed a visit at month 12 and 30 days of safety follow-up.

Primary Outcome Measures:

To determine the maximum tolerated dose of macitentan in combination with dose-dense temozolomide [ Time Frame: Phase I Dose Escalation period (Dose-Limiting Toxicity from Baseline to 28 days for each dose level) ]

Secondary Outcome Measures:

Number of patients with treatment-emergent adverse events (AEs) and serious AEs [ Time Frame: Participants will be followed up for the duration of combination treatment, an expected average of 9-12 months. ]
for all study periods
Number of patients with AEs leading to premature discontinuation of study treatment [ Time Frame: Participants will be followed up for the duration of combination treatment, an expected average of 9-12 months. ]
for all study periods
Incidence of treatment-emergent* marked laboratory abnormalities [ Time Frame: Participants will be followed up for the duration of combination treatment, an expected average of 9-12 months. ]
for all study periods
Number of patients with treatment-emergent ECG abnormalities [ Time Frame: Up to 30 days after discontinuation of macitentan ]
for all study periods
Change from baseline in vital signs [ Time Frame: Up to 30 days after discontinuation of macitentan ]
for all study periods: systolic and diastolic blood pressure [supine and standing], average of the two measurements and pulse rate.
Occurrence of at least grade 2 ALT and/or AST elevation [ Time Frame: Participants will be followed up for the duration of combination treatment, an expected average of 9-12 months. ]
for all study periods
