|Condition or disease||Intervention/treatment||Phase|
|Anaplastic Astrocytoma Recurrent Anaplastic Astrocytoma||Drug: Eflornithine Drug: Lomustine||Phase 3|
This study will consist of 4 study periods of up to 50 months in total, consisting of:
Screening Period - A maximum screening duration of 4 weeks.
Treatment Period - Treatment Arm A up to 24 months; Treatment Arm B up to 12 months.
End of Treatment Visit - A minimum of 4 weeks post last treatment for both arms.
Follow-Up Period - Up to approximately 36 months, or until patient death.
A total of approximately 340 patients will be randomized in a 1:1 ratio to receive either eflornithine + lomustine or lomustine alone.
|Study Type :||Interventional (Clinical Trial)|

Experimental: Eflornithine + Lomustine
Eflornithine dosed on a 2 weeks on, 1 week off schedule + Lomustine dosed every 6 weeks
Eflornithine 2.8 g/m2 administered orally every 8 hours on a 2 week on, 1 week off schedule
Other Name: DFMO
Lomustine 90 mg/m2 administered orally once every 6 weeks
Active Comparator: Lomustine
Lomustine dosed every 6 weeks
Lomustine 110 mg/m2 administered orally once every 6 weeks
- Overall survival [ Time Frame: 4 years ]
- Progression-free survival (PFS) [ Time Frame: 4 years ]
- Objective response rate (ORR) [ Time Frame: 4 years ]
- Clinical benefit response (CBR) based on magnetic resonance imaging (MRI) criteria [ Time Frame: 4 years ]
- OS rate at 18 months (OS-18) [ Time Frame: 18 months ]
- Relevance of OS, PFS, ORR, and CBR to commonly used molecular/genetic biomarkers obtained from most recent pre-study tumor samples [ Time Frame: 4 years ]
- Pharmacokinetic Analysis - Maximum concentrations (Cmax) of eflornithine in plasma will be determined. [ Time Frame: 1 Month ]
- PK - Area under the curve (AUC) of eflornithine in plasma will be determined. [ Time Frame: 1 Month ]
