Brief Summary:

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 The study will end when all patients (excluding those prematurely withdrawn or lost to follow-up) in each part of the study have completed a visit at month 12 and 30 days of safety follow-up.

Arm Intervention/treatment
Experimental: Macitentan
Macitentan in combination with dose-dense temozolomide
 Drug: Phase 1 Dose Escalation
Macitentan 30, 60, 90 mg or higher in 30 mg dose increments, given orally, up to 150 mg, then 225 mg, 300 mg and 375 mg, unless otherwise decided by the Safety Monitoring Committee. Dose-dense temozolomide 150 mg/m2 body surface area alternating 1 week on 1 week off.
Other Names:

  • Macitentan

Drug: Phase 1b
Macitentan given orally and daily at doses/schedule determined from the dose escalation period. Dose-dense temozolomide 150mg/m2 body surface area alternating 1 week on 1 week off.
Other Names:
  • Macitentan
  • dose-dense temozolomide

Drug: Ancillary Study
Macitentan dosed initially for 8-14 days prior to craniotomy, then treatment interrupted from time of craniotomy until 7 days before start of dose dense temozolomide therapy. dose-dense temozolomide 150 mg/m2 body surface area alternating 1 week on 1 week off.
Other Names:
  • dose-dense temozolomide
  • Macitentan


Outcome Measures

Primary Outcome Measures :
  1. 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 :
  1. 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

  2. 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

  3. 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

  4. Number of patients with treatment-emergent ECG abnormalities [ Time Frame: Up to 30 days after discontinuation of macitentan ]
    for all study periods

  5. 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.

  6. 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
